Usage: at the point of inspection and repair of rolling stock for monitoring the status of wheelsets of rail transport. The essence of the invention: method based wheelset is that supports the clamping fixture set crests of the wheel pair, the latter is additionally fixed in the transverse and longitudinal positions and keep it locked state of the wheel pair to the end of the measurement cycle, and as the locking elements are using supports the clamping devices, which are in the form of rollers, the contact surface which return the contact surface of the flange of the wheel pair. The invention also includes a clamping device for a pair of wheels, a device for positioning a pair of wheels, containing a table, made from the clamping device and the support platform, and complex to measure normed linear dimensions of wheel pairs, containing a base, track, coordinate measuring machine. The technical result is an increase measurement accuracy by reducing the influence of various effects on the mechanical part of the system as a whole and devices egley technique for monitoring the status of wheelsets of rail transport and can be used in the inspection points, repair of rolling stock, for example, when the input control after turning on a lathe.

Measurements are determined by the values of the linear dimensions from valid, i.e. those that are regulated by industry standards. These variations determine the wear - metering characteristic elements and sections of the pair of wheels and serve as a further basis on which to address the issue of allowing further exploitation, restoration or culling wheelset.

The results of these measurements are affected by not only the errors from the measurement systems and methodical measurement errors, but also errors from mechanical parts from environmental influences.

The error from the mechanical part depends on the accuracy of the manufacture of rails from the mounting precision, friction in the guides, the presence of backlash, deflection under its own weight of moving parts, the inertia of the moving mass and some other reasons. Error this is a systematic and a random character.

The error from the influence of the environment arises from the deformation of the elements of the measuring system and the measured wheel pair under the action of temperature, humidity and vibration IU the major difficulties not only in the measurement process, but when applying it to the measurement position and the output from it, so methods based wheelset should stipulate the need to compensate the impact of these factors negatively affecting the measurement accuracy.

The known method of basing the wheel, which consists in the fact that the wheel is placed on the lifting table and serves on the position measurement [USSR Author's certificate No. 1415045, CL G 01 7/12, 1988].

This method can only be used in rolling mills and machinery in the production of diameter measurements of solid-rolled wheels and tires rolling circle without their communication with each other in the form of a pair of wheels.

A known method of measuring the profiles of riding wheelset consists in the fact that the wheel pair is installed in the clamping device, is put into rotation and produce measurement, bearing the clamping fixtures install bearing wheelsets [Patent USSR No. 847945, CL G 01 5/08; G 01 B 5/20, 1981].

Moving the pair of wheels in the position measurement is carried out using the reference table, made with possibility of vertical rise, but at the same time functions table finish, except that upon completion of the measurements is as a device for the axial forces in the struts portal increases the load on them and causes additional difficulties associated with providing vibration isolation, rotation, stop, and so on,

The known method based wheelset, taken as a prototype, which consists in the fact that the wheel pair are placed on the supports of the clamping device, is moved to the measurement position is set to the device for axial base for rotation in the measurement process, provide the clamping device [Application NDP No. 262425, CL G 01, 61, 1988].

This method in its implementation involves the use of clamping devices as additional support in the event of axial base pair of wheels and a motor for rotation in the measurement process, but the device is rotated around the vertical axis.

But it does not necessarily fixed position relative to the selected coordinate system and decreases the accuracy of the measurements because of the impossibility of excluding the beating of the pair of wheels, rotating the clamping device.

Since the pair of wheels is symmetric about the horizontal axis, it is important to use this fact in the design of such device, which would perform the functions of Neary.

A device for measuring diameters and the difference between the diameters of the wheels, containing two pairs of driven road wheels, four friction disk mounted on rotating shafts and connected with the sensor information-measuring system, and the friction wheels are the second point of support for the wheels of the first and second wheel pairs [USSR Author's certificate No. 953446, CL G 01 7/12, 1982].

In the system consisting of only one pair of wheels, it is impossible to apply this device due to the lack of tools to accurately basing this wheelset.

A device for measuring profiles of riding wheelset when re-profiling containing the clamping device, the axial node-based wheel pair and a measuring system in which the clamping device is made in the form bearings for bearing units wheelset [Patent USSR No. 847945, CL G 01 B 5/08; G 01 B 5/20, 1981].

This device for lifting and moving the pair of wheels in the position measurement contains the baseplate, but the additional fastening wheelset produce other device in the clamping fixture.

Performing the same clamping device in the form bearings for bearing units wheel poleznoe pair, taken as a prototype, containing a table, provided with supports for placing a pair of wheels, a mechanism for vertically moving it to the measurement position and the drive mechanism of rotation of the wheel pair in the measurement process [Application NDP No. 262425, CL G 01, 61, 1988].

The application of the clamping device with a table, made in the form of a circular plate (disc) that can rotate around its own vertical axis, leads to the appearance of beating during the rotation due to the presence of deviations of different geometric dimensions of the elements of the pair of wheels and a base plate, which affects the measurement accuracy. A large diameter round table contributes to the manifestation of its properties as a kind of flywheel and difficult in the measurement process stop wheelset due to the large inertia of the table.

Because in itself the clamping device which is used in the form of a turntable should have a chance to rise to the height of the measuring position, it is quite logical is on the other table, having this opportunity.

A device for automatic measurement of the diameter of the solid-rolled wheels and tires rolling circle containing the rise of the 1415045, CL G 01 7/12, 1988].

This device is aimed at improving the measurement accuracy due to compensation of errors from inaccurate installation plane measurements.

The controlled placement of the wheels on the lifting table is produced in the supine position (flat), and verification is not a pair of wheels in General, but only the wheel, so that the device can only be applied in the manufacturing process, such as rolling mill, which limits the scope.

A device for positioning a pair of wheels, containing a support table provided with supports for the removal of the pair of wheels with the track and placing it on them, mechanism for vertical movement in her position measurement [Patent USSR No. 847945, CL G 01 5/08; 01 5/20, 1981].

In this device the clamping device and the support table is used as a lift, structurally separated. This leads to the necessity of transmission of the pair of wheels from the support table in the clamping device, which complicates the process of positioning.

A device for positioning a pair of wheels, taken as a prototype containing the support table is provided with supports for placing a pair of wheels, mechanism vertical p. 01, 61, 1988].

In this device, unlike the previous example, the clamping device and the support table (lift) combined. But this is a simplification of the structure adversely affects the accuracy of the measurements, as it does not include protection against knocks when placing the wheel pair on the table and vibration when turning (rotation) of the pair of wheels in the position measurement.

Using the way home, the clamping devices and device for positioning a pair of wheels and assumes a corresponding constructive displayed as part of the measuring stand and complex, designed to measure normed linear dimensions wheelset rolling stock of railway transport.

Known complex to measure normed linear dimensions wheelsets of rail transport, containing a device for measuring the profile, radial runout and diameter, and each of the devices contains the clamping element, illuminators, measuring devices, sensors, image processor and is connected to the common for all these devices to the remote control [the Prospectus of the company "Hegenscheidt" system diagnosis "Hemah linear dimensions wheelset needs to be consistent movement of the pair of wheels from one module to another.

This complex is preferred for diagnostic systems wheelset rolling stock in motion, that is, during operation, but when carrying out this type of work at the point of inspection and repair its use is difficult because of the large size of the complex (especially length), the impossibility of measuring all parameters of the pair of wheels, safety reasons and depending on the environmental conditions (ambient temperature, light, darkness, and so on).

A known system for measuring profiles of riding wheelset when re-profiling, containing a base, track, coordinate measuring machine, comprising a frame, a portal with a fixed racks, which are placed in the device for axial base pair of wheels, and with a traverse, which holds the elements of the measuring system, and a device for positioning a pair of wheels placed in the connector rail, mounted on the frame, and provided with mechanisms for vertical movement of the wheelset and its rotation [Patent USSR No. 847945, CL G 01 5/08; G 01 5/20; 1981].

This complex, in essence, is a measuring stand and equipped with advanced lathe lighting the third with a pair of wheels, and from exposure to environmental factors, which negatively affects the accuracy of the measurement of geometrical parameters of wheel pairs.

A known system for measuring the geometrical condition of the wheel pair and wear work profiles of the pair, taken as a prototype, containing a base, track, coordinate measuring machine, comprising a frame, a portal with a fixed racks, which are placed in the device for axial base pair of wheels, and with a traverse, which holds the elements of the measuring system, and a device for positioning a pair of wheels placed in the connector rail, mounted on the frame, and provided with mechanisms for vertical movement of the wheelset and its rotation, and drives these mechanisms are placed in the pit Foundation [Application NDP No. 262425, CL G 01, 61, 1988]. This complex also does not provide additional protection from bumps, jolts and vibrations generated by the manipulation of a pair of wheels, and from exposure to environmental factors.

The task, which directed the group claimed invention is the development of such technical solutions that would allow the measurement of the normalized l in order to improve the efficiency and quality of these measurements.

A single technical result achieved in the implementation of the claimed group of inventions is to improve the measurement accuracy by reducing the influence of the environment and by reducing shock and vibration impacts during manipulation with a pair of wheels.

This task is solved in that in the method based wheelset, namely, that wheel a couple of sets on the support of the clamping device, is moved to the measurement position is set to the device for axial base, and the clamping device is used to rotate the pair of wheels, to support the clamping fixture set crests of the wheel pair, the latter is additionally fixed in the transverse and longitudinal positions and keep this locked position of the pair of wheels before the end of the measurement cycle, and as the locking elements are using supports the clamping devices, which are in the form of rollers, the contact surface which return the contact surface of the flange of the wheel pair.

Install bearing on the clamping fixture flange of the wheel pairs simplifies the process of removing it from relsovogo aparecem and longitudinal positions likens this operation the installation of the pair of wheels in the bed of the special design, which ensures the rigidity of the fastening pair of wheels relative to the selected coordinate system.

Maintaining the same fixed position of the pair of wheels before the end of the measuring cycle allows measurements with simultaneous fixation, that is, with minimal displacement of the pair of wheels in one direction or another, and these shifts are caused by the geometrical parameters of the wheels.

Use as locking elements supports the clamping device allows you to extend their functionality.

The implementation supports the clamping device in the form of rollers makes it possible to use them simultaneously for transmitting rotation to the wheel, that is, to use them as friction elements.

The execution of the contact surface of the rollers response of the contact surface of wheel flanges provides good friction properties during transmission of rotation, and also eliminates the offset of the wheel pair in the longitudinal direction in one direction or another.

This task is solved in that the clamping device for a wheel pair, containing a table, provided with supports for receiving and placing on them a pair of wheels and enabled LAN in the form of a rectangular flat frame, placed on the base plate, which is connected kinematically to the last, and made with the possibility of rotation about its long axis from a horizontal position into an inclined back and forth, commit in a horizontal position and out of this position, and a support for placing a pair of wheels mounted on each of the short sides of the frame and is made in the form of videos, posted with the possibility of contact with the flange of the wheel pairs in the two lower points symmetrical about a vertical plane passing through the centerline of the wheel pair, and having a contact surface, second contact surface of the flange of the wheel pair, while the clips posted on one of the short sides of the frame, made with the possibility of self-talk to them of wheel flanges and rollers, placed on the opposite short sides of the frame opposite each other, form two pairs of rollers, each of which is mounted on the shaft, one of these pairs is leading, the other is driven, and the drive leading pair inside of the contour of the frame.

The frame can be fitted with a contact lever, made in the form of sticks, a bent part which is placed with the possibility of contact with the nab is the barites mezhrelsovyh space and need to fit within the frame of various elements of assemblies and mechanisms.

Placing the frame on the base plate attaches to the frame with the required stability and creates the conditions for changing the position of the upper plane in space.

Connection kinematically frame with base plate allows for changing the position of the plane of the frame relative the support plate.

The execution of the frame can be rotated relative to the long axis of the frame from horizontal to inclined and back provides conditions for the movement of the pair of wheels with the rails on the frame by crowding as if on a slide during the removal of a pair of the rails and through the escape from this slide when you install a pair of wheels back on the rails.

Performing a frame with a chance of fixing it in a horizontal position provides a consolidation of the pair of wheels on the supports of the frame without danger of spontaneous gathering it from the frame.

Execution frame can be output from the horizontal position (released) provides for tilting of the frame when receiving a pair of wheels or gathering with the last frame at the end of the measurement cycle.

Install supports for placing the pair of wheels on each of the short sides is determined by the nature of their functions, involving the use of them on the first stage for removal of Coles the symmetrical installation of the wheelset relative to the long axis of the frame, and the short axis of the frame.

The placement of these rollers with the possibility of contact with the ridge of the wheel in its two lower points symmetrically relative to a vertical plane passing through the centerline of the wheel pair, provides the conditions for balancing the mass of the wheelset, which facilitates positioning and locating.

The implementation of the rollers with the contact surface, second contact surface of the flange of the wheel pair, provides optimal conditions for fixing ridges in them, and manifestations of frictional properties required for the implementation of rotation of the wheel pair.

Implementation of the clips posted on one of the short sides of the frame, with the possibility of self-talk to them of wheel flanges will give the possibility to automatically maintain the balance wheel pair in the measurement process.

The formation of two pairs of rollers, placed on the opposite short sides of the frame opposite each other, and their connection shafts allows for simultaneous actuation of all of the rollers in the measurement process, which ensures the absence of distortions in the rotation of the wheel pair.

One of the pairs of rollers leading, and the other knows the>the accommodation of the drive leading pair inside the contour of the frame allows the efficient use of this space.

Supply frame contact lever allows without the help of special sensors to make direct contact with the moving (rolling) a pair of wheels.

The execution of the contact lever in the form of sticks, a contact part which is placed with the possibility of contact with the rolling frame wheel wheel pair, provides the condition for the crowding of the pair of wheels on this lever, slide the lever on the wheel and turn it down, as well as the contact arm is rigidly connected to the frame, and it together with the lever rotated on their axes relative to the long axis of the frame.

This task is solved by the fact that in the device for positioning a pair of wheels, containing a table for placing thereon a pair of wheels made with the possibility of renting a pair of wheels with the rails, posting on its supports, vertical movement along the guides in the measurement position and its rotation in the measurement process, the table is made from the clamping device and the support platform, and the clamping device is placed on a support platform connected to the last shock-absorbing elements and PV measurement process, at the same time as means for preload use shock-absorbing elements, the frame of the clamping device in the initial position is located above the level of placement of the rails and the supporting platform in the same position below the level of the placement of the rails.

Implementation of the table of the clamping device and the support platform provides, on the one hand, some independence in the implementation of individual operations of a measurement cycle, and on the other hand consistency of actions in the process of lifting a wheel pair, her home dimension and lowering.

Placing the clamping device on the supporting platform is derived from the condition of some independence of their joint work.

The connection of the clamping device with a support platform damping elements provides the reduction of impact loads exerted a pair of wheels at the moment of transition from the track to the supports of the base frame, and in the process of measuring the preload reference frame to the wheel pair, and most importantly, prevents the transfer of vibrations from the vibration source (in this case, the pair of wheels) on jobs, equipment and devices.

Performing the clamping fixture on p. 2 provides optymalnymi with the possibility of raising the frame clamping device to the wheel pair creates conditions to decrease the displacement of the axis of the wheelset vertically and reduces measurement error, associated with the use of sensors (error contact).

Use as a means to preload damping elements can simplify the design.

The location of the frame clamping device in the initial position above the level of occupancy of the rails provides a condition for lifting the pair of wheels at a certain height without the use of additional mechanisms.

The location of the anchor platform in the initial position below the level of accommodation rails provides the conditions for rational allocation of units and mechanisms.

This problem is solved, finally, and the fact that in complex dimension normed linear dimensions of wheel pairs, containing a base, track, coordinate measuring machine, comprising a frame, a portal with a fixed rack and crossmember, a device for axial-based wheel pair and a device for positioning a pair of wheels and rails are mounted on a statin, a device for axial base pair of wheels placed in racks portal on traverse of the portal measuring system, and a device for positioning a pair of wheels placed in the connector of railway track provided with mechanisms Yong below the level of the bed in the pit of the Foundation, a device for positioning a pair of wheels made under item 3, contains the clamping fixture on p. 2 and provided with a space for accommodating the lamps included in the measuring system, and the platform mounted on the clamping device and connected with the latest cushioning elements, rails placed on the frame with a stop for supporting the platform, and the complex includes a protective case. The device for positioning a pair of wheels according to the point 3 provides improved measurement accuracy by reducing the influence of environmental factors and the dynamic interaction of components and mechanisms during manipulation with a pair of wheels.

The presence of the clamping devices made according to the point 2, in the device for positioning a pair of wheels allows regardless of this device to make a recording of the pair of wheels during the entire measurement cycle.

The placement device for positioning a pair of wheels vibroisolating site with lamps included in a measuring system, expanding the technological capabilities of the device, since it does not need to produce to regulate the>/p>The vibration of this site ensures the absence of any displacement of the lamps so as to provide uniform illumination.

Placing rails on the frame with a stop for supporting the platform allows you to use rails as a constraint upper course of this platform when it moves up vertically.

Performance of a complex with a protective case ensures the reduction of influence of factors of external environment (temperature, air, noise, vibration, and so on) on the measurement process and the protection of the operator and equipment from this influence.

The way home wheelset is as follows.

Wheel pair 1 (Fig.1-4) on the rails 2 is fed to the position where the contact of this pair with the supports 3 devices for positioning (not shown). Installing a pair of wheels on the supports 3 is performed by fixing it in the supports (Fig.1) as in vertical planes I and II, perpendicular to the axis of the wheelset and vertical planes III and IV, parallel to the axis of the wheelset. You get in the planes I and II of the fixation pair of wheels similar to the placement in the prism, and in the planes III and IV is similar to the placement in the guide. This forms a support system wheelset necessary for its rigid attachment relative to selected who is on high, which will be calibrated necessary linear dimensions of the pair of wheels, and there is installed in the device for axial base (Fig.4 shows element 4), fix it relative to the axis of the wheelset 1. After this wheelset is ready for measurements.

Support 3 made with the possibility of rotation and/or stop wheel pair 1 in the measurement process, for a given algorithm, which determines the process at the right time or turn the wheel at a given angle, or stop the wheel at the right place and at the right time.

The clamping device of the pair of wheels includes a table, made in the form of a rectangular flat metal frame 5, is provided with supports for placing a pair of wheels, made in the form of rollers 3 each with the possibility of contact with the wheel wheelset in its two lower points symmetrical about a vertical plane passing through the centerline of the wheel pair.

The rollers 3, placed on the opposite short sides of the frame 5 opposite each other, form two pairs, each of which are connected by shafts 7 and 8. One of the shafts, for example 8, is connected by a transmission 9 drive 10 speed and/or stop wheel pair, therefore, is a leading. The rollers 3 on another shaft 7, are driven from the wheel and transmit the rotation of its shaft, which is the slave.

The frame also includes two axis I, relative to which it can be rotated about the long axis of the frame from horizontal to inclined and back.

These axis II is placed at the center of the short sides of the frame and installed in the support-rotating nodes, supports 12 which smonte is the missing node (Fig.6 shows its location - item 14), which can be performed using well-known so-called locking position.

For output frames from the committed state (in horizontal position), it is provided with exhaust clamps.

To ensure rotation raspikirovki frame in a position in which the pair of wheels is freely rolled with rollers of the frame back on the rails, it is equipped with a mechanism (not shown) of the rotating frame, triggered by the completion of a measurement cycle.

At some distance from the frame may be equipped with a position sensor of the wheel relative to the frame, which is triggered by the approach of the wheel and the signal is sent to the Executive body of the tilt mechanism of the frame.

Frame when it is returned to the horizontal position and fixed itself, at this concluding stage of the removal of the pair of wheels with the rails and place it on supports of the frame. When enabling mechanism for vertical movement in the frame work 5 the clamping device rises to a height at which wheel pair are summed elements of the mechanism of the axial base and clamping in the axial centers. Next, the wheel pair of the drive mechanism of rotation and/or shutdown, as elements which use rollers 3, lead to a defined position by rotation by a specific angle and measure the required linear dimensions of the pair of wheels.

Upon completion of the measurement process a frame 5 with a pair of wheels 12 is lowered to the initial position, incline towards the unloading mechanism, while the pair of wheels is slipping from the frame 5 on the rails 2 and goes depending on the results of measurements on a lathe, or in operation, or to the stock of defective products.

In the case when, instead of the position sensor use the contact lever, the clamping device operates as follows.

A pair of wheels filed on position (Fig. 7-8), moves along the track, runs onto the contact arm 15, podbiraetsya between them.

Frame 5 when this takes place in a horizontal position and locked into position with the locking elements.

In the future, all going the same way as in the case of the example of the clamping device with a contact sensor.
