[0017] As a further improvement of the above solution, both sides of the lower surface of the positioning block are fixedly connected with extension plates, and the surface of the extension plate is plugged with a strong screw seat.

[0018] Through the above technical solution, the positioning block can be fixed by a strong screw seat. After the positioning block is fixed, the connection between the device and the towed object is improved, and it is fixed by the strong screw seat, which is convenient for subsequent personnel to disassemble and assemble it.

[0019] As a further improvement of the above solution, a placement groove is opened in the middle of the upper surface of the supporting platform, and the inner bottom wall of the placement groove is fixedly connected with a protective spring, and the number of the protective springs is four.

[0020] Through the above technical solution, the protective spring can provide shock-absorbing protection for the traction cross frame. When the traction cross frame is impacted by external force, the protective spring is used to unload the force, thereby reducing part of the impact force, improving the protection of the traction cross frame during traction, and extending the service life of parts.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

The gap left between the floating block and the stop block can allow the traction cross frame to have a certain activity space during the traction process. The preset gap of the stop block is the maximum rotation angle of the floating block, which can prevent the traction cross frame from breaking due to excessive floating angle after being impacted when the traction device walks on a road with potholes. The provided rubber protection pad can protect the traction cross frame, reduce the collision impact between the traction cross frame and the stop block, and reduce the risk of surface damage and depression.

[0033] The limiting assembly 2 includes a limiting base plate 201, which is fixedly connected to both sides of the upper surface of the bearing platform 1. One side of the upper surface of the limiting base plate 201 is fixedly connected with a stop block 202, and the outer surface of the stop block 202 is fixedly connected with a rubber protection pad 203. The traction cross frame 7 can rotate inside the auxiliary bearing 4 through the floating blocks 6 connected on both sides. The gap left between the floating block 6 and the stop block 202 can allow the traction cross frame 7 to have a certain activity space during the traction process. The preset gap of the stop block 202 is the maximum rotation angle of the floating block 6, so as to limit it and prevent the traction cross frame 7 from breaking due to excessive floating angle when the traction device is walking on a road with potholes and is impacted. The rubber protection pad 203 can protect the traction cross frame 7, reduce the collision impact between the traction cross frame 7 and the stop block 202, and reduce the risk of surface damage and depression.

[0034] A bearing rod 5 is fixedly connected inside the auxiliary bearing 4, and a floating block 6 is fixedly connected to one end of the bearing rod 5. The floating block 6 can rotate inside the auxiliary bearing 4 through the bearing rods 5 on both sides, providing a floating angle for the traction device when it is subjected to external force.

[0035] A traction cross frame 7 is fixedly connected to one side of the surface of the floating block 6. The traction cross frame 7 is rotatably connected to the inside of the auxiliary bearing 4 through the floating block 6. When subjected to external force, the traction cross frame 7 can have a certain rotation angle inside the auxiliary bearing 4, so that the traction device can move forward stably.

[0036] A support plate 8 is fixedly connected to one side of the surface of the limiting base plate 201, and semicircular blocks 9 are fixedly connected to both sides of the upper surface of the support plate 8. The support plate 8 can support and fix the semicircular block 9, thereby improving the stability of the semicircular block 9 when pulling an object, preventing the semicircular block 9 from loosening and falling, and improving the safety protection of the equipment.

[0037] A coupling shaft 10 is clamped inside the semicircular clamping block 9, and a positioning block 11 is provided in the middle of the surface of the coupling shaft 10. The coupling shaft 10 is clamped inside the semicircular clamping block 9, so that the towed object can be connected to the device.

There are four protective springs 15. The protective spring 15 can provide shock-absorbing protection for the traction cross frame 7.

After the positioning block 11 fixes the connecting shaft 10, the connection between the device and the towed object is improved, and it is fixed by the strong screw seat 13, which is convenient for subsequent personnel to disassemble and assemble it. The positioning block 11 strengthens the stability of the device when towing the object to prevent the towed object from sliding off. The traction cross frame 7 can rotate inside the auxiliary bearing 4 through the floating blocks 6 connected on both sides, and the floating blocks 6 and the stop blocks 202 The gap left between them can allow the traction cross frame 7 to have a certain amount of room for movement during the traction process. The preset gap of the stop block 202 is the maximum rotation angle of the floating block 6, thereby limiting the protection thereof to prevent the traction cross frame 7 from breaking due to excessive floating angle after being impacted when the traction device is walking on a road with potholes. The rubber protection pad 203 provided can protect the traction cross frame 7, reduce the collision impact between the traction cross frame 7 and the stop block 202, and reduce the risk of surface damage and depression. When the traction cross frame 7 is impacted by external force, the protective spring 15 is used to unload the force, thereby reducing part of the impact force, improving the protection of the traction cross frame 7 during traction, and extending the service life of parts.
