The invention concerns a trip meter to detect the real status of galleanist frame chassis, with the plane of the frame, parallel to the reference plane formed by the base points of the wheels, and transported her and independently floating auxiliary carriage.

Track gauge of this type is well known from the prospectus "EAT SAT Geometer Wagen" company Plasser Theurer. Above the plane of the machine frame is large sled cabin and the powerful drive chassis.

The second trip meter, called satellite carriage, is connected to the laser emitter to create a reference chord and can connect to the machine frame for General moving under the plane of the frame.

From U.S. patent N 4691565 already known machine for measurement or, respectively, reception and/or even adjusting the position of the path ahead of the moving carriage as it moves on unadjusted way. This travelling carriage, equipped with a laser emitter and a traction drive, for a total move over end, made in the form of a ramp end region of the machine, can it move. This machine, designed as a carriage measuring path has a laser receiver, located in its front end portion, as well as various devices for detecting and nakapikit, what podwojnym work on obtaining ratings for the geometry of the path precede costly measurement and assessment of the true state path. Through measuring machine EAT-SAT, attempts were made mechanization of these operations. Between the auxiliary carriage mounted in a fixed point, and continuously nathusii on her path meter as the reference chord is used a laser beam. When this is measured boom lift to the laser reference chord, digitized and stored in computer. By means of additional measurements basic distances to fixed points you can identify the difference with a preset position and to calculate the necessary offset and downs, which can serve as input for computer control machine tamping sleepers. Through geometric truck SM, device 17 m in length and weighing 30 tons, separating on the site for receiving and transmitting part, these works must be performed quickly, economically and safely before the movement of trains on the adjacent working path.

The present invention is the creation of a track gauge of the specified first type, which, while reducing Constantinian this task is solved by that trip meter designed to identify the true state path with respect to a given state of a path that contains a frame, based on the driving mechanisms, the plane of which is parallel to the reference plane formed by the anchor points of the wheels, a laser receiver mounted on the measuring carriage connected to the frame with the possibility of vertical and lateral movement relative to this truck, an auxiliary carriage, Rethimno mounted on the frame, a laser emitter mounted on the carriage with the possibility of vertical and lateral movement relative to it, the height is limited conditional inclined plane, forming with the base plane in the front in the direction of potenzmitel part of the angle is equal to 5-10aboutwhile the imaginary line of intersection of the conditional inclined plane and the plane of the frame parallel to the reference plane and perpendicular to the longitudinal direction of movement of the trip meter.

Track gauge of this type with a low overall height and with auxiliary carriage which is particularly useful way can be combined with track laying machine, in particular, with calopodinae machine, with the aim of comprehensive beneath is controlled from the driving cab of calopodinae machine. This combined movement provides a very simple execution path meter with auxiliary motor, necessary only for work use, relatively low power, but with an appropriate angular range of the bounding plane becomes possible rather large overall length of the frame of the chassis to achieve the most satisfactory result drive during movement. In addition, this type of trip meter with auxiliary carriage can without constructive cost and accordingly perevalochnij work to dovetail with the already in operation sporopollenin machines. Movement of this type in the General system of machines with calopodinae machine provides a dimension and hit the road in one road stop, even logical costs can be significantly reduced in comparison with the formerly divided into stages progress.

A preferred improvement of the trip meter when using the above-mentioned advantages provides unlimited functional use at comfortable driving cab. The improvement provides a fast function is on measuring trolley.

Remote solution such traction hook provides for the exclusion associated with security breaches leaving the machine very fast separation directly after reaching the place of work.

On the grounds of the frame of the meter with geometric circuit may be connected to the panel Jack, eliminating the impact of the amortization engine on the measurement results.

Shows signs provide improved measurement results, and working the steps required for measurements, for the most part be carried out remotely.

Reasonable improvement in combination with detection of the difference between the true and the specified state route provides precise binding of the laser oscillator to a fixed point on the path.

These features lead expedient way to the smaller arrows lifting while achieving more accurate results.

Another improvement trip meter enables easy and quick fastening of the auxiliary carriage serving under the frame of the meter, so the meter freely articulated with the rule of law the meter, when using ramps guaranteed fast translation auxiliary carriage from the transfer position into the working position.

By installing, composed of the preferred and proposed measures, the work performed previously in two separate working step, namely survey and Polivka the way, can be carried out in one working step in achieving a particularly economical and structural benefits. All work with the special economic feasibility requires only a single lock, and due to the universal adjusting movement, and low overall height track gauge its constructive simplification lies in the auxiliary motor is required only at low operating speeds, and simple working the cabin. Logical cost precise time coordination of the different stages also significantly reduced compared with the known solutions. Finally, the advantage is the elimination of conflicts of interest when measuring and podboinye work is performed by the same entrepreneur.

In Fig. 1 presents a side view of the limit of the meter, coupled with a partially shown podbiel machine, with the pragmatic view of another example of execution of the trip meter.

Track 1 meter (Fig.1) has a frame 2 of the chassis with the plane of the frame 3 parallel to the reference plane formed by the base points 4 wheel driving mechanism 5. This parallelism occurs in the normal case, when the springs both running gears 5 are loaded equally. On the plane of the frame 3 in the rear part 6 of the machine are the internal combustion engine 7. Before him (marked by arrow 8) in the direction of travel 1 meter is located sled cabin 9 with the control device 10. Sled cabin 9 is placed in the recess 11 of the frame 2 meter. The top line 12 of the contours formed by the engine 7 and the driving cabin 9, are located below the bounding plane 13, which is to the reference plane formed by the base points 4 wheel driving mechanism 5 or, respectively, to the plane of the frame 3 at an angle of from 5 to 10about. While the bounding plane 13 with the plane of the frame 3 forms at the end of the trip meter 1, the front in the direction of the line of intersection 14 perpendicular to the longitudinal direction of the machine and parallel to the plane of the frame or base plane. Trip meter 1 can be independently moved with your own the m 5 is having a banding wheel 15 of the measuring trolley 16, vertically moved with the actuator and connected to the frame 2 of the meter. It's equipped with laser receiver 17 with CC-matrix camera, the meter 18 slope, and two opposite transverse relative to the machine direction of the video camera 19 for video sensing, located in the area of each of the retaining wheel 15 section of the route. Laser receiver 17 is installed on the measuring carriage 16 can be moved vertically and in the transverse direction by means of the actuator 20. Here, in addition, applies the probe 21 of the path of the probing roller, rolling on the rail head.

Frame length 2 meter, advocating for a front suspension mechanism 5, larger than the total length of the auxiliary carriage 22. It is equipped with a drive device 23 can be lifted out of the way and can connect with the front end of the frame 2 meter. As shown in phantom lines, during the movement of the auxiliary carriage 22 is protruding over the front driving mechanism 5, the frame 2 of the meter, so it can easily connect to another machine.

Before operation of the traction hook 30 stanesti meters from podbiel machine 32 along the path 24. Once achieved subject to measurement part of the way, the extension limit of the meter 1, the auxiliary carriage 22 down device 23 and, respectively, of the frame 2 and falls on the path 24. Then the auxiliary carriage 22 is shifted to the nearest fixed point of the path and is positioned on the color markings on the rails. Then measured the true distance and height 24 relative to a fixed point of the path. Registered data wirelessly transmitted to travel 1 meter. After such a measurement at a fixed point in the path of the auxiliary carriage 22 are nominated for another 5-10 m and stops there. Laser emitter 27 is configured by a laser receiver 17, which meanwhile together with the measuring carriage 16 has been lowered on the path 24. Using a suitable mechanical stop auxiliary carriage 22 is fixed on the rails way so that the exhaust from passing trains is excluded. During the measurement through the respective mobile radio device is a radio communication between the personnel servicing the auxiliary carriage 22 track 12 meter and crew podbiel machine 32.

After adjustment of the laser emitter 27 and the receiver 17 track Ismay 22. Using SDS-matrix camera, located in the laser receiver 17, simultaneously measured height and direction. When exceeding track the position of the laser receiver 17 and the adjusting paths, as well as distance traveled, measured by the device 21 measurement path at a given distance is calculated corresponding to the true boom lift. The calculation begins only when the trip meter 1 is directly in front of a fixed point on the path, which is the auxiliary carriage 22, and stops strictly in relation to this point. Only then any position of the chord formed by the laser emitter 27 may computer by re-estimated on a theoretical chord, put in a basis set of arrows lifting.

During this calculation, the auxiliary carriage 22 can again using your own auxiliary motor 25 to move to the nearest fixed point on the path. After calculating the true arrows lifting they are compared with in-memory specified by arrows lifting and identifies the respective correction values of the displacements and slopes. These correction data using radio devices 36 are transmitted to the Central control device is processing for the respective drive control photopolymer or straightening units.

The laser beam generated in the oscillator 27, does not split, but in the form of a round cross section of the beam is directed to the receiver 17. When you receive this gives the advantage of high intensity, which ensures reliable reception. The possibility of displacement of the laser oscillator 27 through the device 28 of the transverse motion gives the advantage to the receiver 17 this leads to fewer arrows lifting. With the help of other oblique position of the laser chord should be regulated in a great area.

Under the CCD-matrix camera laser receiver 17 is understood YZ-adjusting device (transverse configuration Y, vertical configuration Z). As an active receiving surface of the camera for the desired reception area is too small, an appropriate adjustment. It is continuously carried out by the computer and an appropriate tuner. When this area of regulation Z is 500 mm, the area adjustment Y-1000 mm camera Position adjustment unit is measured by the absolute encoder. Laser point through frosted glass and optics is projected on a CCD camera and its position is calculated by the computer on the appropriate program and transmitted to the host computer 36 trip meter. Blagodatnoe in driving the cab 9 monitor image, the accurate positioning of the limit probe 1 relative to the corresponding fixed point of the path. This is done by positioning the middle of the measuring wheel truck 16 on the color mark on the head and neck rail. Educated banding wheels 15 of the measuring axis at the same time designed as a telescopic axis in order to measure rut.

After three installation 31 is connected in the engine system due to the fact that the auxiliary carriage 22 unit 23 to the front of the machine part of the trip meter 1, and the trip meter 1 towing hook 30 is connected to podbiel machine 32. Thanks to the free review over path 1 meter maintenance personnel can easily guide the placement of the driving cab 34 in the direction of the arrow 8.

Another option trip meter (Fig.3) 39 is supported on the driving mechanisms 40 frame 42 with the plane 41, parallel to the plane of the path. Rear in the direction of the end of the frame 42 of the meter is the Central control unit 43 with the seat 44. Immediately in front of him is the storage location independently floating auxiliary carriage 45. She can navigate along the machine and connected with the frame rails 42 ri movement and the work of the ramp 47 by means of the actuator can be returned to its original position, in which it is located almost parallel to the plane 41 of the frame directly above the frame 42 of the meter. Trip meter 39 may be moved by electric motor 49 and the drive 50.

The bounding plane 51 makes with the plane 41 of the frame angle 8about. Located on the frame 42 of the meter auxiliary carriage 45, the control device 43 and the seat 44 are under this restrictive plane 51 so that podbiel machine attached to the rear end region, with the General movement has an unobstructed view of the road.
