[0003] During the operation of smart urban rail, real-time monitoring and fault diagnosis of key components of the urban rail system can promptly identify potential safety hazards, avoid accidents, and ensure the safety of passengers and staff. The fault detection system can quickly locate the source of the fault, reduce troubleshooting time, and speed up maintenance response, thereby reducing operational interruption time caused by faults and improving the operating efficiency of the entire urban rail system.

[0004] The track inspection vehicle plays an important role in railway track inspection. It can detect the internal and external geometric states of the track. However, under extreme weather conditions, such as snow accumulation, the operation and detection accuracy of the track inspection vehicle will be affected. Snow accumulation on the track not only affects the normal movement of the track inspection vehicle, but also reduces the accuracy of detection. When snow accumulates on the track, manual snow removal is generally used, which is time-consuming and labor-intensive, seriously affecting the efficiency of fault detection. Summary of the invention

[0005] The present invention aims to provide an urban rail fault detection device, which can remove snow on the track while a track inspection vehicle is inspecting the track, without the need for manual cleaning, thereby increasing work efficiency.

[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-6 As shown, a city rail fault detection device includes a track inspection vehicle 1 arranged on a track, a snow removal component and an installation component for installing the snow removal component are arranged on the front side of the track inspection vehicle 1, the snow removal component includes two push frames 9 arranged symmetrically on the left and right, a shovel head 11 is arranged at the front end of the push frame 9, a connecting piece 12 is arranged on the push frame 9, and a connecting frame 14 for adjusting the angle of the connecting piece 12 is arranged at the rear end of the connecting piece 12, the installation component includes a first installation structure for installing the connecting frame 14 arranged on the side wall of the track inspection vehicle 1 and a second installation structure for installing the push frame 9 arranged at the bottom of the track inspection vehicle 1.

[0021] The first mounting structure includes a fixed block 3 arranged on the side wall of the track inspection vehicle 1, a limit block 4 is arranged on the outer side of the fixed block 3, and a stop block 6 is rotatably connected to the outer side of the limit block 4 through a rotating shaft 5. The second mounting structure includes a limit frame 2 arranged at the front end of the bottom of the track inspection vehicle 1 and matching with the corresponding push frame 9, and also includes a limit groove arranged at the bottom of the track inspection vehicle 1, and the push frame 9 passes through the limit frame 2 and is inserted into the limit groove.

[0022] The connecting frame 14 is a strip-shaped structure. A "J"-shaped buckle 15 connected to the limit block 4 is arranged at intervals on one side of the connecting frame 14. The width of the curved part of the buckle 15 gradually decreases, and the front end is close together. The side of the buckle 15 is hollowed out to form a lightweight groove 10. The connecting piece 12 is a curved surface and tilted outward. The rear end of the connecting piece 12 is provided with a protruding portion 13 protruding upward, and the rear end of the protruding portion 13 is connected to the connecting frame 14. A plurality of buckles 15 are arranged on the connecting frame 14 for connecting with the limit block 4. The buckles 15 at different positions are connected with the limit block 4, and the position of the connecting frame 14 is changed, thereby adjusting the inclination angle of the connecting piece 12, while ensuring the cleaning effect, reducing the resistance of the track inspection vehicle 1. By arranging the protruding portion 13 on the upper part of the connecting piece 12, the snow will no longer approach the track inspection vehicle 1 upward when it reaches the protruding portion 13, so that the snow can slide along the connecting piece 12 tilted outward to both sides of the track, thereby ensuring that the track inspection vehicle 1 can perform normal inspection.

[0023] The push frame 9 is made of elastic material, the push frame 9 is arc-shaped, and the side and top of the push frame 9 are hollowed out to form a lightweight groove 10. Prevent snow from accumulating on the surface of the push frame 9 during snow clearing, increasing the weight of the push frame, reducing the efficiency of snow clearing, and affecting snow clearing.

[0024] The push frame 9 includes a curved section for connecting with the limiting groove, the front end of the curved section is connected with a straight section, the front end of the straight section is connected with an inclined section inclined outward, the front end of the inclined section is connected with the shovel head 11, and the lightweight groove 10 is arranged between the straight section and the inclined section.

[0025] The limiting grooves include a first limiting groove 7 arranged at the front side of the track inspection vehicle 1 and a second limiting groove 8 arranged at the rear side of the track inspection vehicle 1. Two limiting grooves are provided, which are used for installation and fixation of the snow removal assembly in the working state and the non-working state respectively.

[0026] While clearing the snow, the track is inspected through a laser detector installed on top of the track inspection vehicle 1, and the track information is collected to generate images and transmitted back to the control center. The track is fully inspected and fault problems are analyzed (this is existing technology and will not be repeated here).

[0027] When there is no snow to be cleared, remove the "J"-shaped buckle 15 from the limit block 4 and fit it together with the push frame 9, take the push frame 9 out of the first limit groove 7, move it to the rear side and insert it into the second limit groove 8, so that the snow clearing assembly is stored at the bottom of the track inspection vehicle 1 to save space.

[0028] A snow-clearing component is provided, so that the snow on the track can be cleared while the track inspection vehicle 1 is inspecting the track, without the need for manual cleaning, thereby increasing work efficiency; a mounting structure is provided to fix the snow-clearing component, and the angle of the connecting piece 12 can be adjusted according to the thickness of the snow when clearing the snow, thereby reducing the resistance of the track inspection vehicle 1 while ensuring the snow clearing effect. The device has a simple structure, is quick and easy to use, and has a low production cost, making it easy to produce and use.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
