[0031] In specific use, the initial position of the guide device 3 is at the highest position in the liftable range, and at this time, the guide device 3 has no contact with the steel rail 5. When the rail gauge inspection device runs to the turnout area, the straight track or the curved track is selected according to the need, and the positions of the guide devices 3 on the left and right sides of the rail gauge inspection device are determined according to the selected track. If the straight track is selected, the position of the outermost steel rail in the straight track in the turnout area relative to the running direction is determined to be on the left side or the right side.

The pull rod oil cylinder 16 is connected with the pull rod oil cylinder fixing frame 14 through screws. Thus, the downward movement of the lifting plate 19 realizes the downward movement of the pull rod oil cylinder fixing frame 14, and the pull rod oil cylinder 16 works until the target position (i.e., the guide wheel 18 is opposite to the outer side of the rail head of the steel rail 5) is reached. Then, the pull rod oil cylinder 16 works, and the piston rod 15 drives the auxiliary plate 17 and the guide wheel 18 to perform the extension and retraction movement in the horizontal direction. The piston rod 15 indirectly pushes the guide wheel 18 to contact the outer side of the steel rail 5, so as to change the running direction of the rail gauge inspection device.

[0036] Further, the driving device 1 comprises three spur gears 9, the three spur gears 9 are directly meshed with each other, belong to three-stage transmission, drive the rear wheel 12 to rotate, and then drive the whole gauge inspection device to move.

In specific use, only the measuring device 4 at the front is matched with the displacement sensor, and the measuring device at the rear mainly functions to guide the rail gauge inspection device to pass through the harmful space of the frog, so as to enhance the stability of the vehicle body during movement.

[0039] Further, the measuring wheel 23 is at least three, and the three measuring wheels 23 are arranged at intervals based on the direction of movement.

[0040] Further, the turnout area rail gauge inspection device further comprises a camera 34 and a solar panel 35, the camera 34 is three in total, and is installed at two sides and a middle position of the mounting bracket 33, can monitor the four around of the working area, and can master the dynamic path of the rail gauge inspection device in real time.

[0041] According to the above technical scheme of the utility model, the optional working process is as follows:

[0042] The track gauge inspection device reaches the starting position where the track gauge needs to be detected. The measuring device 4 starts to prepare. The horizontal lead screw 38 is driven by the horizontal lead screw motor 39 to rotate, further driving the measuring wheel 23 to reach the standard track gauge position. The guide device 3 is driven by the vertical lead screw motor 37 to rotate the vertical lead screw 20, further making the guide wheel 18 opposite to the outer side of the steel rail. Then, the piston rod 15 is controlled to extend or retract by the pull rod oil cylinder 16, further making the guide wheel 18 reach the limit position of the standard track gauge allowable deviation. Then, according to the weather conditions at that time, the solar panel 35 or the storage battery 7 is reasonably used to provide power for the reduction motor 8, further driving the rear wheel 12 to rotate. After the above preparations, the track gauge inspection device starts from the main line.

[0043] When the track gauge is smaller during the driving process, the measuring device 4 on both sides of the vehicle body 36 contacts and is pressed against the inner side of the steel rail 5. The limiting plate 24 cooperates with the sliding groove 27 to guide. The support frame 22 cooperates with the spring 26 in the moving plate 21 through the spring connecting column 25. Then, the spring 26 is deformed under the pressing action. The displacement sensor monitors the deformation displacement of the spring 26 to determine the track gauge deviation. When the track gauge deviation exceeds the reasonable range, the calibration device 2 uses the water pump 31 to extract the dye in the dye tank 29, and sprays the dye on both sides of the abnormal track gauge area through the two water pipes 30, which is convenient for maintenance personnel to repair. When the track gauge is within the reasonable range of the railway standard, the track gauge inspection device continues to detect the track gauge of other track areas.

[0044] When the track gauge is larger during the driving process, the measuring wheel 23 cannot measure the track gauge deviation when it is in the standard track gauge state. At this time, the measuring wheel 23 is in contact with the steel rail 5 and is pressed by the rotating motion of the horizontal lead screw 38. The spring 26 is controlled to move within the preset range by the displacement sensor. At the same time, the distance that the moving plate 21 moves from the standard track gauge state to the contact between the measuring wheel 23 and the steel rail 5 is monitored. Whether the track gauge of this area meets the standard requirements is determined according to the monitored distance that the moving plate 21 moves. If it does not meet the requirements, the area is marked.

[0045] When the track gauge inspection device reaches the turnout area, the straight line or curved line of the detected section is selected according to the need. Then, it is determined which guide device 3 on the left and right sides of the track gauge inspection device works, and the other one needs to be reset to the initial position by the rotating motion of the vertical lead screw 20 driven by the vertical lead screw motor 37. For the guide device in the working position, the guide wheel 18 is opposite to the outer side of the rail head of the steel rail 5. The piston rod 15 indirectly pushes the guide wheel 18 to contact the outer side of the steel rail 5, thereby changing the driving direction of the track gauge inspection device.

[0046] When the rail gauge inspection device reaches the frog part harmful space, the measuring wheel 23 in the measuring device 4 plays an important role, which has three rollers, and the measuring device 4 is provided with a spring 26, which can make the rollers flexibly adjust the direction during movement, the first roller is in a suspended state when passing through the frog part harmful space, the second roller and the third roller are in contact with the side of the steel rail 5, at this time the rail gauge inspection device operates normally; then the first roller is in contact with the side of the steel rail through the frog heart harmful space, the second roller is in a suspended state, and the third roller is in contact with the side of the steel rail, which can still ensure the normal operation of the rail gauge inspection device; finally, the first roller and the second roller pass through the frog part harmful space, and the third roller is suspended until the measuring wheel 23 completely passes through the frog part harmful space. It should be noted that the measuring wheel 23 closest to the front end in the direction of travel is the first roller, then the first roller along the direction away from the direction of travel is the second roller and the third roller respectively.

[0047] Further, three cameras 34 are installed on both sides and the middle position of the mounting frame 33, which can monitor the environment around the working area, and master the dynamic path of the rail gauge inspection device in real time. The completion of the above work marks that the rail gauge inspection device successfully completes the passing and rail gauge detection of the main line and turnout area.
