Description

The utility model relates to railway transport and is intended to monitor the condition of the railway track; it can be used to measure rail gauge, mutual elevation (level of one rail relative to another), as well as the distance between the working faces of the core and counter rail, the ordinates of the translated curves and the width of the gutter.

Known devices for monitoring the condition of the railway track, made on the basis of portable travel measuring templates of the type TsUP-1D, TsUP-2D, TsUP-3D, which are mechanical devices with scale devices for measuring linear dimensions and with air-bubble levels for angular measurements and for measurement of turnouts.

The closest in technical essence and the achieved result is a device for monitoring the rail track, made in the form of a measuring trolley type PT-7MK, developed by LLC "TVEMA". (Operation manual 2822.00.000RE. Device for monitoring the rail track (track measuring trolley PT-7MK) www.tvema.ru, 2000

The well-known PT-7MK measuring trolley includes an autonomous power supply unit, a rail gauge, a rail level sensor, a microprocessor recorder for storing, analyzing and displaying sensor readings, which has a non-volatile memory and an interface for transmitting measurement data through a communication adapter to a track computer or to the Department of Way database. The rail level sensor is made according to the principle of a pendulum tracking the direction of the gravitational vertical in the cross section of the path.

The output signal of the rail level sensor is proportional to the transverse roll angle of the measuring trolley frame relative to the horizon line.

An optical linear displacement sensor, which is a comb with slots, is used as a rail gauge, and the microprocessor recorder calculates the rail gauge by the number of pulses from the optical element of the linear displacement sensor.

With all the advantages of the well-known PT-7MK measuring trolley, it is worth noting the insufficient accuracy of the measurement of the required parameters and the practical impossibility of its use for measurement in the loaded mode, which is fundamentally important for modern computerized track cars, which have high demands on the accuracy of measuring the gauge and level of relative position surfaces of rail heads.

The technical result, the achievement of which the creation of this utility model is aimed at, is to simplify the design of the device, increase the accuracy of measuring the track gauge and the level of the relative position of the surfaces of the rail heads, as well as providing the possibility of placing the device in the vicinity of the measuring rollers of the track gauge and providing the possibility of the mode, "on- line »with an on-board automated system (BAS) for a computerized track-measuring laboratory car.

The technical result is achieved by the fact that in the device for measuring the gauge and the level of the relative position of the surfaces of the rail heads, comprising a metal case with an autonomous power supply unit installed inside it, a linear displacement sensor, a sensor for tilting the rail threads and a microcontroller, a temperature sensor and a pocket personal computer are introduced, moreover, the output of the temperature sensor is connected to one of the inputs of the pre-processing unit

signals, an information channel connected to the microcontroller, the output of which is connected to the input of a personal digital assistant, the output of the latter is connected to the input of the on-board automated system of a computerized track measuring laboratory car, while the metal casing installed between the rail heads is box-shaped and fixed on one side of the casing emphasis interacting with the lateral inner surface of the head of one rail, and a folding handle to which is attached a holder with a handheld personal computer installed on it, and on the other side of the box-shaped case a movable bracket is installed, on the right and left shoulders of which one tip is fixed, the ends of which are abutted against the lateral inner surface of the other rail, and oriented orthogonally mounted in the central part of the movable bracket two permanent magnets relative to each other, while in the cavity of the box-shaped body there is a linear displacement sensor associated with a movable bracket with by moving it along a flat bearing in the guides under the action of a spacer spring located in the guides of the casing and ensuring that the movable bracket is pressed against the side inner surface of the rail head, and an inclinometer and a temperature sensor are fixed in the middle part of the box-shaped housing cavity.

A device for determining the track width and the level of the relative position of the surfaces of the rail heads comprises a stand-alone unit

power supply 1 of Fig. 1 linear displacement sensor 2, inclinometer 3 and temperature sensor 4. Unit 1 and elements 2, 3 and 4 are structurally located inside the box-shaped body 9 of Fig. 2. Block 1 provides power to all the main elements and blocks of the device. The inputs of the elements 2, 3 and 4 are connected to the block 5 of the preliminary data processing. The microcontroller 6 controls the processes of conversion and measurement, and also provides the ability to transfer data to a personal digital assistant (PDA) 7 of FIG. 1, from which the measurement results are automatically or by an additional command transferred to the database of the on-board automated system (BAS) 8 of FIG. 1 radio channel or via the PDA communication port.

On one side of the box-shaped body 9 of Fig. 2, a folding handle 10 and a fixed stop 11 are installed, which is made interacting with the side inner surface of the head of one rail. A holder is attached to the folding handle 10 with a pocket personal computer 12 of FIG. 2 mounted thereon (for example, of the type HPIPAQ h × 4700). On the other side of the box-shaped body 9, a movable bracket 13 is installed, on the right and left shoulders of which one tip is fixed 14. The ends of these tips 14 are made abutting against the side inner surface of another rail. In the central part of the movable bracket 13, two permanent magnets 15, 16 are installed, oriented orthogonally relative to each other and designed to more securely fix the movable bracket 13 on the rail. In this case, one of these magnets is pressed against the upper surface of the rail, and the other magnet is on the side surface of the same rail, thereby ensuring fixation of the movable bracket on the rail head in mutually orthogonal planes.

Placed in the cavity of the box-shaped housing 9 (figure 2), the linear displacement sensor 2 (figure 1) is connected with a movable bracket 13 (figure 2, 3, 4) with the possibility of its movement on a flat bearing (figure 2, 3, 4 not

shown) in the guides of the casing (not shown in FIGS. 2, 3, 4) under the action of a spacer spring 17 located in the guides and ensuring that the movable bracket 13 is pressed against the side inner surface of the rail head.

Figure 2, 3, 4 shows the basic design of the device for determining the gauge and the level of the relative position of the surfaces of the heads of the rails, corresponding to a variant of the device for its use in the track gauge, i.e. for measuring the gauge and determining the elevation of one of the rails relative to the other. In this case, the handle 10 is shown in the folded (transport) position. If it is necessary to measure the width of the groove, the ordinates of the translated curves, as well as the distance between the working faces of the core and the counter rail, additional devices are used that are attached to the base elements shown in Figs. 2, 3, 4.

A device for determining the gauge and the level of the relative position of the surfaces of the heads of the rails works as follows.

The housing 9 of the device is shocklessly installed between the inner side surfaces of the track rails in the gap between the measuring trolley and the wheel and possibly closer to the place of lowering of the measuring rollers. In this case, first install the end of the housing with a fixed stop 11 (figure 2), and then, acting on the thrust spring 17, install the other end with the movable bracket 13 located on it. Since the movable bracket 13 is connected to the linear displacement sensor and pressed against the inner surface of another rail, the distance between the tips of the fixed stop 11 with the tips of the movable bracket 13 in contact with the inner surface of the other rail corresponds to the width of the rail track. The elevation of the rolling surface of one rail over the corresponding surface of the other rail is automatically calculated by the angle of inclination between the indicated surfaces, which is measured using an inclinometer 3.

In order to significantly reduce the measurement error due to changes in ambient temperature, a temperature sensor 4 (Fig. 1) is introduced into the measurement circuit, the data of which is used to compensate for the specified error.

To install the application software, it is necessary to write the line.prp file from the installation disk included in the delivery package using standard KPK7 tools. After that, the KPC7 work program is ready for use. The device operates automatically under the control of KPK7, the operation buttons of which are located on the basis of KPK7. So when you press the "Measure" button, the operator will receive the current values of the measured parameters in the "Template" and "Level" fields. A view of the screen when operating in this mode is shown in FIG. 5. In the middle of the screen is the status bar of the Bluetooth port. Here a message is received, received from BAS8 of a computerized laboratory car via the Bluetooth port, if the connection is established. The “Do not record” softkey serves to cancel the measurement results and proceed to re-measurement.

Setting up the program consists in setting four correction factors and a data exchange port with the device. The screen view of the CPC7 in the setting mode is shown in Fig.6. The setting of the coefficients is carried out during the adjustment and adjustment work. If the values of the coefficients were accidentally lost, they can be restored by pressing the button "Update constants" Fig.6.

Checking the correctness of the configuration work is performed as follows:

1. install the device housing on the rails;

2. turn on KPK7;

3. make measurements of the template and level, noting the position of the body on both rails;

4. Turn the device case 180 ° and set its ends to the marked places;

5. Re-measure the pattern and level.

The measured values of the gauge (“template”) and the level of the relative position of the surfaces of the rail heads (“level”) should not differ from the corresponding parameters obtained for the two measurement cases discussed above by an amount greater than the permissible error. Otherwise, additional correction is necessary. It should be noted that a correctly configured device does not require additional correction over a long period of time.
