Description

The device relates to the technique of railway transport and is intended to measure the parameters of the rail track of the railway track.

Known devices for measuring the parameters of the rail track of the railway track. These include, for example, a wearable device for measuring the parameters of the rail track of a railway track, which provides measurement, recording and digital indication of the distance traveled, the width of the rail track (template) and the mutual excess of one rail thread relative to another (level) during the repair and restoration work and operation of the railway track. Subsequent processing on a personal computer of information obtained using the device is provided. (Track machines. Proceedings of the 1st scientific and practical conference of the Ministry of Railways of the Russian Federation, Department of Railways and Structures, State Unitary Enterprise Kaluga Plant "Remputmash". - Kaluga: Izd. AKF Politop, 2002, p. 181).

With all the advantages of this device, it should be noted its drawback - limited functionality, in particular, it does not provide a measurement of the longitudinal track profile, track profile in plan, bending arrows of the rails of the railway track, etc., requires additional processing of the information received.

The closest in technical essence and the achieved results is a device for measuring rail track parameters of a railway track, comprising a running trolley including a support wheel and first and second measuring wheels and a measuring wheel located on the same axis above one of the rail threads, the supporting wheel being connected to measuring wheels mounted at an angle of 90˚ relative to the direction of movement of the bar, on which the gauge is mounted, on the measuring wheel mounted track sensor, on the axis, with knitting the measuring wheels, a heading indicator is installed, and the outputs of the track and track gauges and heading sensors are connected through a controller to a computer. This is a known device (RF Patent for the invention No. 2261302 dated 04/17/2003, 7MKI ЕВВ 35/00) is taken as a prototype.

Further, in the above prototype formula, equivalent signs are used: instead of the signs “support wheel” and the first and second measuring wheels and measuring wheel located on the same axis above one of the rail threads, the signs are “first and second rail trolleys equipped with wheels”, in in particular, to exclude the possibility of jamming of the "support wheel", which, in fact, performs the function of a rail car; instead of the sign "installed at an angle of 900 relative to the direction of movement of the bar - the sign of" telescopic yoke ", because the absence of the sign of" telescopic "excludes the possibility of functioning of the gauge of the gauge"; instead of the sign of "gauge of the gauge" - the sign of "gauge of the rail gauge "; instead of the heading indicator, there are signs of roll and pitch sensors.

With all the advantages of this device, it should be noted its disadvantages - low operational characteristics of the heading indicator (large weight, size and power consumption, time spent on accelerating and stopping gyroscopes, setting the initial values of the measured parameters, the need to correct errors during operation, very high cost, etc. .), reduced accuracy of indirect measurements of a number of parameters of the rail track of the railway track.

The technical result, the achievement of which the creation of the proposed device is directed, is the elimination of these disadvantages of the prototype, i.e., simplification, reduction of manufacturing costs and improving the accuracy of the device.

The technical result is achieved by the fact that in the device for measuring the parameters of the rail track of the railway track, containing the first and second rail trolleys, equipped with wheels and connected by a telescopic beam, on which the gauge of the track gauge is mounted, one of the wheels is connected to the track sensor on the first rail car roll and pitch sensors are installed, and the outputs of the sensors are connected through controllers to a computer - distance sensors to the rail, a second pitch sensor, an angular velocity sensor are introduced into the device and course and transceiver, the telescopic traverse is equipped with quick-disconnect electrical and mechanical connectors, one of which has three degrees of freedom, three distance sensors to the rail are installed on each rail trolley along the rail surface, and one distance sensor to the rail is installed relative to the side working surface of the rail, a second pitch sensor and an angular rate sensor are mounted on the second rail carriage, moreover, the computer is made wearable and connected to the controllers via a transceiver.

The figure shows a structural diagram of the device.

In order to simplify the perception of figure graphics (top view), a number of structural elements of the device that do not have fundamental importance for it (attachment points, operator’s handle, wheel suspensions, cable network, batteries, etc.) are simplified or not shown conditionally.

To consider the principle of operation of the device, we introduce the left coordinate system in which the 0X axis is the roll axis and the direction of movement of the device, the 0Y axis is the pitch axis and the 0Z axis is the course axis. Axes 0X and 0Y lie parallel to the horizon plane. Accordingly, the rotation of the device around the 0X axis will be called roll, around the 0Y axis - pitch, around the 0Z axis - course. The device during normal operation is moved using the handle of the operator (not shown conditionally).

A "device for measuring rail track parameters" (hereinafter the term "device" may be used) consists (see figure) of the first rail carriage 1 (PT1) and the second rail carriage 2 (PT2), which are connected using a telescopic beam (TT) ) 3 by means of quick disconnect rigid connections (conventionally not shown). The telescopic traverse of the TT 3 has degrees of freedom around the Y, Z axes and along the Y axis, for example, in the area of articulation with PT1 (in section AA in the figure). To ensure the required stiffness of the quick disconnect rigid connection from the PT2 side in a real design, it is possible to use a strut 4 on the TT 3.

The device also includes a wearable computer 5 (for example, a “laptop” type), which is equipped with a transceiver (a transceiver of a radio link with electrical components of the device, which is standard on a laptop).

On PT1 and PT2, the main components of the design and the electrical circuit of the device are installed (some of them are not shown conditionally). At the ends of PT1 and PT2 according to the “bicycle” scheme, wheels 6, 7 (on PT1) and 8.9 (on PT2) are installed. Rail threads are conventionally shown by dash-dotted lines. The contact surfaces of the wheels PT1 and PT2 with the rail (taking into account its cradle) correspond to the contact surfaces of the wheels of the rolling stock. A sensor 10 is connected to the wheel 9, which is mounted on a PT2.

The distance sensors to the rail (DRR) 11, 12, 13 (mounted on PT1) and DRR 14, 15, 16 (installed on PT2) are located along the rolling surface of the rail. These sensors are dotted in the figure, because mounted on the side of the rails.

DDR 17 (mounted on PT1) and DDR 18 (mounted on PT2) are located relative to the lateral working surface of the rail. DDR 17, DDR 18 are located below TT3 and therefore are indicated by a dotted line in the figure.

The pitch angle sensor ДУТ 19 is installed on РТ1, and ДУТ 20 - on РТ2. A roll angle sensor (ДУК) 21 and a course angular velocity sensor (ДУСК) 22, the sensitivity axis of which is parallel to the Z axis (if the conditional plane lying on the contact points of the wheels 6, 7, 8, 9 with the rails, is parallel to the X0Y plane, are also installed on РТ2 ) FLS 19, 20 and FLK 21 are made, for example, based on accelerometers. A first controller 23 is installed on PT2. A second controller 24 and a transceiver 25 with an antenna are installed on PT1. The antenna of the transceiver 25 and the batteries designed to power the device are not conventionally shown in the figure.

TT 3 and PT 1 are mechanically conjugated by mutual linear displacement using, for example, a spring-loaded telescopic connection (degree of freedom along the Y axis). Their position relative to each other can be determined using the sensor of the track gauge (LH) 26 (in the figure this mechanical pairing is shown in bold dotted line).

Electrical cables (not shown conditionally in the figure) between PT1, PT2 and TT 3 are equipped with quick-disconnect electrical connectors.

"Device for measuring the parameters of the rail track of the railway" works as follows.

The operator and his assistant install the device on the rails of the railway track and bring it into working position, turn on the power to the device and wearable computer 5, check the initial condition of the equipment, enter the required initial (initial) data into the wearable computer 5, and get to work. In the process, the device is pushed along the rails of the track using the handle of the operator (conditionally not shown in the figure).

"A device for measuring the parameters of the rail track of the railway track" allows you to measure and document the following regulatory parameters of the railway track in relation to the track:

- distance according to the sensor of the path 10;

- speed according to the information of the path sensor 10;

The path sensor 10 generates signals proportional to the speed of the device and the path traveled by it. The wearable computer 5 through the transceiver 25 synchronizes the operation of the equipment RT 1, RT 2 and TT 3, the final processing of information received from the first controller 23 and the second controller 24, its indication, storage and delivery, if necessary, and in real time.
