A controller is installed on the front of the vehicle body 1, and a speed sensor is installed at the bottom of the front of the vehicle body 1. The controller enables the dual-axis motor 41 and the speed sensor to work together. If the speed sensor provides feedback to the controller, the controller adjusts the speed of the dual-axis motor 41. A battery is installed on the inner wall of the vehicle body 1 to power the electrical equipment. A drive assembly 4 is installed inside the vehicle body 1, and the drive assembly 4 includes a dual-axis motor. 41. There are two dual-axis motors 41, which are respectively installed at the bottom of the inner wall of the vehicle body 1. The dual-axis motors 41 provide traction power for the device. The two motors output synchronously to ensure the stable operation of the vehicle body 1. A rotating shaft 42 is installed on the output shaft of the dual-axis motor 41. A guide block 43 is installed at the bottom of the inner wall of the vehicle body 1 at the position corresponding to the rotating shaft 42. A bearing that is rotatably connected to the rotating shaft 42 is installed on the inner wall of the guide block 43 and on the surface of the rotating shaft 42. The bearing supports the rotating shaft 42 and limits its radial runout. The end of the rotating shaft 42 away from the dual-axis motor 41 passes through the guide block 43 and the vehicle body 1 in sequence and extends to the outside of the vehicle body 1. A traveling wheel 44 is installed thereon. The traveling wheel 44 contacts the top surface of the urban rail track and drives the device to move.

[0023] An adjustable-height traction connection assembly 2 is provided on the right side of the fixed housing 100. The traction connection assembly 2 includes a slide rod 21. The upper and lower ends of the slide rod 21 are respectively fixedly connected to the top and bottom of the inner wall of the fixed housing 100. The slide rod 21 is fixedly connected to the inner wall of the fixed housing 100 by welding. A slider 22 is slidably connected to the surface of the slide rod 21. The surface of the slider 22 slides in contact with the inner wall of the fixed housing 100, which guides the slider 22. The slider 22 moves up and down with the adjusting rod 27, driving components such as the concave plate 23 and the connecting arm 24. The concave plate 23 is installed on the right side of the slider 22 and is fixedly connected to the slider 22 by welding. The left side of the concave plate 23 slides in contact with the right side of the fixed housing 100. A rotating shaft is rotatably connected to the inner wall of the concave plate 23 through a bearing. A connecting arm 24 is installed on the surface of the rotating shaft. The connecting arm 24 transmits traction force and simultaneously... The angular deviation between the test vehicle and the tractor should be checked. A recess 25 is installed on the right side of the connecting arm 24. The recess 25 is fixedly connected to the connecting arm 24 by welding. A pin 26 is provided on the recess 25. The tractor ear of the test vehicle is inserted into the recess 25, so that the pin 26 passes through the recess 25 and the tractor ear, realizing a quick connection between the two. An adjusting rod 27 is installed on the front of the slider 22. The front end of the adjusting rod 27 passes through the fixed shell 100 and extends to its outside. A locking nut 28 is threaded on the surface of the adjusting rod 27. A fixing washer 29 is sleeved on the surface of the adjusting rod 27 and on the back of the locking nut 28. The front and back of the fixing washer 29 are in close contact with the locking nut 28 and the fixed shell 100, respectively. The locking nut 28 and the fixing washer 29 cooperate to lock the height of the adjusting rod 27 after adjustment. The fixing washer 29 improves the friction during locking, thereby improving stability.

[0024] The fixed housing 100 is connected to the vehicle body 1 via a limiting and disassembly assembly 3. The limiting and disassembly assembly 3 includes two insert blocks 31 and two movable plates 32. The insert blocks 31 are installed on the left side of the fixed housing 100 respectively. The insert blocks 31 are fixedly connected to the fixed housing 100 by welding. A slot 33 is provided on the right side of the front of the vehicle body 1, corresponding to the position of the insert blocks 31. The left side of the insert block 31 passes through the slot 33 and extends into it, contacting the inner wall of the slot 33. The insertion of the insert block 31 into the slot 33 achieves the initial positioning of the fixed housing 100 and the vehicle body 1. The shapes of the insert block 31 and the slot 33 are... The trapezoidal shape ensures that the insert 31 will not move left or right or up or down when inserted into the slot 33. It also works with the locking block 34 and the slot 35 to prevent the insert 31 from moving back and forth when inserted into the slot 33. The movable plate 32 is located inside the vehicle body 1, and its surface slides in contact with the inner wall of the vehicle body 1. A locking block 34 is installed on the right side of the movable plate 32, corresponding to the position of the insert 31. A slot 35 is provided on the left side of the insert 31, corresponding to the position of the locking block 34. The right side of the locking block 34 extends from left to right through the slot 33 and the slot 35. The inside of the slot 35 contacts the inner wall of the slot 35, and the locking block 34 is inserted into the slot 35 to achieve a secondary locking between the fixed shell 100 and the vehicle body 1. A reinforcing plate 36 is installed on the right side of the top of the inner wall of the vehicle body 1, and a positioning rod is installed on the top of the left side of the movable plate 32. The left end of the positioning rod passes through the reinforcing plate 36 and extends to its outside. By setting the positioning rod, the stability of the movable plate 32 when moving left and right is improved, and the phenomenon of the movable plate 32 shifting is avoided. A threaded rod 37 that is threadedly connected to the movable plate 32 is rotatably connected to the groove on the right side of the inner wall of the vehicle body 1 through a bearing. The threaded rod 37 uses a triangular thread with a thread angle of 60° and a thread helix angle less than the friction angle, which enables mechanical self-locking. The left end of the threaded rod 37 passes through the movable plate 32 and the reinforcing plate 36 from right to left and extends to the outside of the reinforcing plate 36 where a rotating block 38 is installed. The right side of the rotating block 38 is in rotatable contact with the left side of the reinforcing plate 36. A bearing that is rotatably connected to the threaded rod 37 is installed in the groove of the inner wall of the reinforcing plate 36 and on the surface of the threaded rod 37. By setting the reinforcing plate 36 and the bearing, the threaded rod 37 is supported and stabilized, preventing the threaded rod 37 from shifting during rotation.

[0025] When the traction connection assembly 2 needs to be disassembled, first open the fixed door, then rotate the rotating block 38. The rotating block 38 drives the threaded rod 37 to rotate, the threaded rod 37 drives the movable plate 32 to move to the left, and the movable plate 32 drives the locking block 34 to move to the left and separate from the locking groove 35. At this time, the fixed shell 100 can be pulled forward, and the fixed shell 100 drives the insertion block 31 to move forward and separate from the slot 33, thus completing the disassembly.

[0026] In use, adjust the height of the connecting arm 24 and the concave block 25 according to the height of the traction ear of the testing vehicle. When adjusting, first loosen the locking nut 28 to release the limit on the adjusting rod 27, and then make the connecting arm 24 drive the concave plate 23, the slider 22, the connecting arm 24, the concave block 25 and the adjusting rod 27 to move up and down. When the connecting arm 24 and the concave block 25 are adjusted to the appropriate position, tighten the locking nut 28 to lock the position of the adjusting rod 27 again.

[0027] Push the vehicle body 1 so that the recess 25 on the right side of the fixed shell 100 is aligned with the traction ear at the rear of the test vehicle. Insert the traction ear completely into the groove of the recess 25, take out the pin 26, and pass it through the hole on one side of the recess 25 to the other side, ensuring that the pin 26 is completely passed through the hole of the traction ear.

[0028] The controller on the front of the vehicle body 1 sets the operating speed according to the detection requirements. Low-speed precision detection: set 0.5-2km / h to ensure that the detection equipment has enough time to collect data; rapid transfer: set 3-5km / h to balance efficiency and safety. The controller starts the dual-axis motor 41, and the two dual-axis motors 41 start synchronously, driving the traveling wheels 44 to roll along the urban rail track through the rotating shaft 42.
