The invention relates to the field of rail transport, and is intended to control the track.
Known potenzmitteln cart containing the frame and resting on the measuring wheel traverses. On the frame are mounted position sensor path level, the position sensor path across the width of the track associated with measuring wheels through the yoke, the Registrar, the stock.
The method of controlling the position of the track is implemented by a device, where the wheel performs two functions: moving the cart along the rails and the measurement template. Is the clamp beam with wheels to the rails. When changing the gauge rod together with the screw do reciprocating motion, with the possibility of coverage of the helical grooves of the screw and rotate the axis of the sensor. The signal from the sensor is amplified and fed to the Registrar (USSR, A.S. No. 1041613, IPC EV 35/00,04).
The disadvantage of this method of controlling the position of the track and devices, it implements, is the lack of accuracy of the measurement. Not reliable contact of the measuring wheel with the rail. The occurrence of buoyancy force when the focus of the measuring disk radius on the surface of the rail leads to outright trolley with rails, and it reduces accuracy when processing results.
A device for measuring the parameters of the track containing the its acceleration sensor, working the axis of which is parallel to the axis of the pair of wheels mounted on buochs wheels. Dont forget the wheels are contactless sensors of the rails in the plan, as well as the sensor of the traversed path, connected with the Registrar. In addition, the device contains a template (USSR, A.S. No. 1555405, IPC EV 35/00).
This method of measuring the parameters of the track is characterized by the fact that as a template can be used lowered truck or removable mechanism of the measuring gauge. Before driving device template is used to define the initial values of the gauge. Changing gauge determined in accordance with the position of the rails in the plan.
The disadvantage of this method of measurement of parameters of the track and devices, it implements, is the lack of measurement accuracy due to the fact that at the initial alignment device of a touch point of the template to the inner edges of the rails does not correspond to the actual touch points of the ribs, especially when defects heads. Disk flange of the wheels cause the setting error and reduce the accuracy of the measurement, as they can not provide unequivocal contact at the measurement points. The use of sensors horizontal accelerations, as well as proximity sensors makes the same error, but it does not promote the achievement of the structure required accuracy.
You know the measurement device of railway track containing the reference wheel pair bezraboticej wheels, rigidly connected to the axle. On the supporting wheel pair installed all the working elements of design: measuring disks connected by a thrust through the spring to pull the drives. Discs made with a rubber tire for the passage of harmful space switch.
The method of measurement of railway track is implemented by a device that clamps the measuring disks from the inside to the side edges of the rails by means of a spring and rod, the role of the plungers for compressing the measuring disks relative to the wheel.
The disadvantage of this method of measurement of railway track and devices, it implements, is the lack of precision measuring gauge track. The measurement error of the track path will occur due to the shape of the measuring wheel (conical disk), a manual check of all parameters. The device measurements of railway track is rather complicated and cumbersome, requires precise alignment and stability of the springs.
The most famous is potenzmitteln cart containing a frame supported on wheels, installed on the sensor gauge. Frame potenzmitteln truck with abgene rod. On the hub of the wheel sensor is installed path. The frame is based on rigidly associated wheel. Wheels are made of two disks of different diameters, are rigidly connected with each other.
The method of measurement of railway track is implemented potenzmitteln truck which install wheels on the rails, the sliding frame rod to lock the wheels in the lateral surface of the rails. When changing the gauge rod makes a reciprocating motion and rotates the axis of the sensor. The signals from the sensors are received in the Registrar (Technical conditions 2822.00.000 THE Device for control of a rail track, M, April, 2002).
The disadvantage of this method of controlling the position of the track and devices, it implements, is the lack of measurement accuracy due to the lack of reliable contact of the measuring wheel with the rail and the occurrence of buoyancy force when the focus of the measuring disk radius on the surface of the rail that leads to outright trolley with rails, and it reduces accuracy when processing results. When the geometry of the wheels and the lack of fixation of the stem there is no possibility to measure turnouts.
The technical result of the invention is to improve the measurement accuracy by eliminating the possibility of gatherings trolley with rails, which leads to disruption of the continuity of measurements, sat the pits of the algorithm and the difficulties occur when decoding the recording, increase the convenience of operation by eliminating the need for constant monitoring by the operator for the position of the trolley, expand the functionality of the truck due to the measurement of a rail track turnouts and increase measurement accuracy by matching points of contact of the measuring rollers of the device to the contact points of the measuring probes standard (exemplary) template when measuring gauge, and also due to the exclusion of the influence of defects in the rail head on the dimension of the template.
This result is achieved by a method of controlling the position of the track, consisting in the installation of the device on the rail gauge, measure distance traveled, over the rails, gauge, check the data and adding the value of the distance between the measuring elements, includes the installation of wheel pairs on the frame of the device with one hand tightly and with the other hand with the ability to swing relative to the transverse axis, the dimension of the gauge by setting the measuring elements on the lateral surface of the rail to measure the distance to the inner surface of the rails relative to the frame and the fixing of the measuring elements in an arbitrary position, and the device controlling the position of elsuwege way, containing the frame with the attached wheels, gauge distance traveled mounted on the wheel, the sensor is exceeded, rail lines, gauge gauge, the Registrar, drove has a suspension device, where the applied pair of wheels, one of which is rigidly mounted on the frame of the device, and the other with the ability to swing relative to the transverse axis fixed to the frame of the device; the locking elements and the additional sensor is a linear displacement sensor measuring gauge, with sensors measuring gauge located on the frame on the inner side of each rail and provided with spring-loaded measuring elements with the possibility of fixing them locking elements associated with sensors measuring gauge.
