The rim is made with the ribs.

Figure 1 shows a General view, side view; figure 2 is a front view; figure 3 is a top view; figure 4 - gear and figure 5 - block diagram of control.

Device for remote detection of objects hidden on the railway, contains mounted on self-propelled trolley 1 source of penetrating radiation 2 and the detector 3 connected via a cable 4 power supply 5 and the microprocessor 6. To the last connected unit 7 controls the actuators move 8 self-propelled truck 1, block 9 information processing and signaling and blocks 10 and 11 control the detector 3 and the camera 12.

The device consists of three detectors 3 with the corresponding control units 10 and is provided fixed on the frame of the self-propelled truck 1 rod 13 with a drive of rotation 14 and block 15 of its management. Moreover, two detector 3 is placed at the free end of rod 13 with the possibility of coverage of their work areas respectively on both sides of the railroad tracks, including the outer sides of the rails 16. The third detector 3 located in the middle part of the frame of the self-propelled truck 1 with coverage of the working area of the internal space between the rails 16, including the inner side of the output of two additional detectors 3 are connected to respective inputs of the microprocessor 6, to which is additionally connected to the respective blocks 10 of their control and the unit 15 for controlling the drive of rotation 14 of the rod 13.

Wheel 17 self-propelled truck 1 mounted in bearings 18 on each side of the frame and made egg-shaped with a longitudinal axis of rotation 19.

On the wheel rim 17 are made of the flanges 20.

The axis of rotation 19 of the wheel 17 is located above the level of the rail head 16 of the railway track.

To improve the permeability in the spring and autumn period, the wheel 17 may be provided with a closed cover. These tires can swap pneumatic pump as the passage of the trolley 1 in one or the other side.

A wheel rim 17 may be made in the form of a metal cylinder, on the outer surface of which is made of the flanges 20.

The power source 5 in the form of batteries placed on the trolley 1 for Autonomous power supply drives the television camera 12, the actuators 8, 14, and equipment detectors 3.

Drive rotation 14 of the rod 13, which consists of two separate handles, made in the form of the gear 21 with the motor 22. The gear 21 is composed of the drive wheel 23 fixed on the shaft of the electric motor 22, and the two gears 24 and 25, mounted on the shafts 26 and 27 parallel to the shaft of the motor 22. The latter is installed in the gear housing 21 on both sides of the drive wheel 23.

The device core is placed by the remote control 28.

The device operates as follows.

The self-propelled carriage 1 moves to the railway track in the space between the rails 16. The actuators move 8 provide both its longitudinal and transverse movement in all four directions. Straight blunt and sharp ends of the ovoid wheels 17 are located in different directions. It concerns the movement "back and forth" and "left-right". In the first case, there are the major wheel 17, and the side of the wheel 17 is turned off and slide on the surface. In the second case, on the contrary. Wheels 17 aureobrunneus forms with wheels 20 roll through one rail 16 on the stretch or in a few rails on the station. Because the carriage 1 has a rotary device, its passage through the rails 16 is carried out with the inclusion of the transverse actuator 8. The actuator 8 is switched on by the operator remotely via infrared radiation from the console 28. Then they can also switch actuator 14, which expands the handle bars 13 and sets them across the railroad tracks at a 90°angle. Moreover, the handle rod 13 in advance were located in different directions along the trolley 1. In the working position of the handle represent together with gear 21 a whole.

They can be console mounted on the gears 24 and 25 or made integral with them. Sprockets at their ends allow you to carry out the limited rotation in a horizontal plane at an angle of 90°. Gears 24 and 25 simultaneously rotate sprocket wheel 23 in different directions, one clockwise, the other counterclockwise, and Vice versa, when you reverse the motor 22.

Two detector 3, placed at the ends of the handles, cover their work areas respectively on both side of the railway track, including the outer sides of the rails 16. The third detector 3, located in the middle part of the bogie frame 1, covers his work area of the internal space between the rails 16, including their inner side. This is needed to avoid interference from the rails 16. When the movement of the trolley 1 between the rails 16 detectors 2 are included in the operation panel 28.

The size of the truck 1 is significantly less than the width of the railway track, so to cover the side areas for rails 16 required two folding handles. Their drives can be microelectrophoresis, because the device is small in size and requires little power.

Truck 1 remotely moved by the actuator 8 forwards and backwards and so is the inspection of railway tracks by the camera 12 and three detectors 3.

Two main (front and rear) wheels 17 mounted in bearings 18 on the axes 19, simultaneously rotate in one selected by the employee towards one drive motor 8, which on the shaft and eeda next two established stars, United two chains with sprockets on the respective axes of rotation 19. The carriage 1 is carried out by commands from the control console 28 via the control block 7 connected to the microprocessor 6. The design of the actuator 8 for transverse movement of the trolley 1 is similar to the drive.

On the curves of the track sections required correction of the direction of movement of the truck 1 by the simultaneous operation of the longitudinal and transverse drives 8. Truck 1, moving forward, as it slides one way or the other lateral side and remains on the longitudinal axis of the railway track.

Camera 12 operates according to commands from the remote control 28 and control block 11 and passes through the microprocessor 6 signals to the display panel 28 to the employee in the vicinity. The signals from the source of penetrating radiation 2 through the detectors 3 are on a railroad track, which comes in blocks of 10 control and the microprocessor 6 and the console 28. In case of presence of foreign objects on the railway hear a beep and the indicator light on the remote control 28 control light. When the blocks 10 control converts the signals into digital codes that are passed to the inputs of the microprocessor 6. From the output of the microprocessor 6, the signals in the block 9 data processing and alarm system that is remotely connected to the remote control 28. Robot is to stop the device, camera 12 again examines this place.

In the case of visual detection by the camera 12 hidden objects, a decision on their removal or neutralization.

The power source 5 can be placed on the trolley 1. Equipment detectors 3, gears 8 and 14 is connected via a cable 4, for example, the AC voltage of 220 C.

For the best terrain camera wheels 17 can alternately descend and zakachivatsja pumps from self-drive, remotely activated by the remote control 28.

The device can be used to detect hidden objects and obstacles on the railway track.

Depending on the detector 3, for example, are equipped with generators neutron rays, x-rays or ionizing radiation, as well as frequency synthesizers NQR (nuclear quadropoly resonance), the device can detect explosives and drugs on the railway track.

The efficiency of the device for remote detection of objects hidden on the railway, is reliable in operation due to the maximum approaching him detectors and interference.
