Description

The invention relates to the field of diagnostics of the state of the rail track of the railway and tram tracks.

The “Device for the technical inspection of the rail track” is known, which contains running rollers, a U-shaped frame, in the lower part of which there are viewing mirrors, over which reflecting mirrors are symmetrically located on opposite sides of the U-shaped frame in the diagonal plane, and on the central longitudinal axis U-shaped frames in the plane of the horizontal shelf are sequentially shielding mirrors, while the device has a drive handle (AS USSR No. 861157, 61 K 9/10, 1979).

Despite the fact that the device is compact, it has a number of significant disadvantages:

- low accuracy and unreliability of the results in identifying defects in the track rail track;

- large errors associated with the numerous operations of this technological chain for making measurements;

- selective control;

- the impossibility of measuring the deviation of the track gauge of the rail track, as the main parameter in diagnosing the state of the track track;

- the inability to control the position of the rail gauge on the level.

Parts are measured on a disassembled engine, which increases the complexity of the process.

Another technical solution is known “Method and device for monitoring the state of the rail gauge”, containing an inertial measuring module connected to the on-board computer, which is designed to calculate the position of the rail gauge according to the level of subsidence and the arrow of the bend of the rail gauge according to certain coordinates using the inertial navigation algorithm points of contact of the left and right wheels of the wheelset, associated with the gauge of the rail gauge (p. RU No. 2123445, 61 K 9/08, E 01 35/00, 1998).

The disadvantages of this device are the following factors: its low reliability and high cost of the equipment included in the device, such as a computer, and the unreliability of the computer lies in its complexity and frequent failures during operation, which leads to additional labor costs for its repair, in addition , the computer does not register the measurement result, but only provides digital data that must be calculated to obtain the final result.

The objective of the invention is to increase the reliability of the device, reduce its cost, the exclusion of the calculation of the measurement results, that is, the ability to read the measurement results without calculation directly on the recorder.

The technical result of the invention is to increase the operational safety of the rolling stock.

This is achieved by the fact that in the proposed device for the technical control of the rail gauge when the vehicle is moving, comprising recorders designed to measure deviations of the rail gauge, the position of the rail gauge by the level of its subsidence, “humps” and depressions associated with the contact elements, according to the invention introduced vertical parallel inner and outer racks, rollers made with the possibility of interaction with the lateral working inner surfaces of the side track, rollers, execution capable of interacting with the upper working surfaces of the rail track, slopes, some ends of which are connected to the clips of the rollers, and others to the respective posts, one of the recorders is made in the form of a dial indicator, placed at the end of one of the internal posts and connected with contact elements in the form of rollers made with the possibility of interaction with the lateral working surfaces of the rail gauge, the shaft of this recorder has contact with the upper end of another inner rack, while between In the uprights, in the upper and lower parts, there are springs installed on the upper surface of two pairs of bosses placed on the same axis, holes are made in the inner racks, in which there is an axis with a sleeve to which the bracket is attached at one end, the other end serves for fastening to the floor of the laboratory car, the second recorder is made in the form of a metric ruler attached to the inner pillar, and two arrows mounted on the upper ends of the outer pillars, two pairs of grooves are made on the outer pillars, located dix one axle placed in these grooves fingers movably therein, wherein the fingers have guides disposed both outside and from inside the racks.

The technical result is provided by the implementation of contact elements.

The proposed device for the technical control of the rail track when the vehicle is shown in the drawings.

Figure 1 presents a General view of the device;

figure 2 - fragments of the device.

The proposed device for the technical control of the rail gauge when the vehicle is moving comprises recorders 1, 13, designed to measure deviations of the rail gauge and the position of the rail gauge by the level of its subsidence, “humps” and depressions associated with contact elements 2, 3, 4, 5 , 6, 16, 17, 18, 19, 20, vertical parallel internal 6 and external racks 16, slopes 5, 20.

Contact elements in the form of rollers 2 are made with the possibility of interaction with the lateral working inner surfaces of the side track, and contact elements in the form of rollers 17 are made with the possibility of interaction with the upper working surfaces of the rail gauge.

One of the registrars 1, made in the form of a dial gauge and designed to measure deviations of the rail gauge, is connected to the rollers 2 through their axles 3 and clips 4 of slopes 5, one ends of which are connected to clips 4, and the other to internal and parallel between themselves struts 6, on one end of which the recorder 1 is placed in the form of an indicator of a watch type, while the rod 7 of the recorder 1 is in contact with the upper end of the other inner rack 6, between the inner racks 6, in the upper and lower parts, springs 9 mounted on the upper surface of two pairs of bosses 8 located on the same axis, holes are made in the inner posts 6, in which the axis 10 is placed with a sleeve 11, to which the bracket 12 is attached at one end, its other end is used for fastening to the floor of the car laboratories, the second recorder 13 is made in the form of a metric ruler attached to the inner rack 6 of a metal strip 14, and two arrows 15, mounted on the upper ends of the outer racks 16, on the outer racks 16 there are two pairs of grooves 21 located on one si, in the grooves 21 are placed fingers 22 with the possibility of movement in them, and the fingers 22 have stops 23 located both on the outer and on the inside of the uprights 16, while the contact elements in the form of rollers 17 are in interaction with the upper working surfaces of the rail ruts.

The device operates as follows.

The device is attached due to the axis 10, the sleeve 11 and the bracket 12 to the floor of the laboratory car, and due to the tension of the spring 9 with the bosses 8 acting on the vertical posts 6 and rollers 2, together with their axles 3, clips 4 and slopes 5, they are forced the rollers 2 fit snugly against the working inner side surfaces of the rail gauge, and the rollers 17 with axles 18 and clips 19 to the working upper surfaces of the rail gauge, due to their weight and the weight of the groove 21 of the fingers 22 and their stops 23, while the racks 16 move freely strictly vertically due to its grooves 21 fingers 22 and stops 23 up and down.

Then the laboratory car is moved along the rail track, and at this time the rollers 2 and 17, rolling around the track, react to all its defects and transmit signals to their faults, through intermediate parts to registers 1 and 13, which are pre-set to the nominal value of the rail gauge “0” - marks, and deviations in one direction or another from “0” - marks of arrows 15 of register 13 and arrows of register 1 above the permissible values indicate that the rail track is faulty and therefore needs to be restored or replaced.

Thus, the proposed technical solution increases its reliability and reduces the complexity of the measuring process.

This device will allow during the operation of rolling stock to exclude accidents and thereby increase the safety of railway traffic.
