Detailed implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , the present invention provides a technical solution: a trailer frame convenient for positioning and installation, including a trailer platform 1, a tire 4 is installed through the outer surface of the trailer platform 1, a groove 2 is arranged on the outer surface of the trailer platform 1, and a stopper 3 is fixedly installed at one end of the trailer platform 1 close to the groove 2. A first motor 8 is fixedly installed at one end of the trailer platform 1 close to the stopper 3, and the output end of the first motor 8 penetrates the side surface of the trailer platform 1. A cable reel 9 is rotatably installed at one end of the trailer platform 1 close to the first motor 8. One end of the cable reel 9 is connected to the output end of the first motor 8, and a steel cable is arranged inside the cable reel 9. Tie hooks 21 are evenly arranged on the outer surfaces on both sides of the trailer platform 1.

[0030] When the faulty vehicle has no power and cannot be driven, the steel cable in the cable reel 9 can be connected to the faulty vehicle, and then the cable reel 9 is rotated by the rotation of the first motor 8 to pull the faulty vehicle onto the trailer platform 1. The front wheels of the vehicle are limited by the groove 2 and the stopper 3, and at the same time, the vehicle can be secondarily fixed by passing a rope through the tie hook 21.

[0031] One end of the trailer platform 1 close to the stop 3 is provided with a rotating mechanism, which facilitates the installation of the trailer frame through the rotating mechanism. The rotating mechanism includes: a bogie 5, which is rotatably installed at one end of the trailer platform 1 close to the first motor 8, and tires 4 are rotatably installed on both sides of the bogie 5. One end of the bogie 5 away from the groove 2 is rotatably installed with a towing frame 6, and the towing frame 6 is inclined. A cross bar is arranged between the towing frames 6. One end of the towing frame 6 away from the bogie 5 is fixedly installed with a clamping ring 7. One side of the trailer platform 1 is provided with a mounting base 17, and the mounting base 17 is fixedly installed on the frame of the rescue vehicle. The outer surface of the mounting base 17 is penetrated by a pin 19. One end of the pin 19 located inside the mounting base 17 is fixedly installed with a transverse retaining ring 18, and a spring 20 is arranged between the transverse retaining ring 18 and the mounting base 17.

[0032] When it is necessary to use the trailer platform 1 for towing, the trailer can be driven to one side of the trailer platform 1 to make the towing frame 6 close to the mounting base 17 at the tail of the trailer. Then, the towing frame 6 is lifted and rotated. The rotation of the towing frame 6 drives the bogie 5 to rotate, so that the tires 4 rotate together, which is convenient for adjusting the angle and height of the towing frame 6. Then, the clamping ring 7 at the top of the towing frame 6 is lifted to the same height as the mounting base 17. Then, the pin 19 is pulled to place the clamping ring 7. After releasing the pin 19, the spring 20 will push the transverse retaining ring 18 to drive the pin 19 downward to fix the clamping ring 7, which is convenient for the docking and positioning adjustment of the towing frame 6 and the trailer, without the need to adjust the position of the trailer.

[0033] A sliding mechanism is arranged inside the vehicle platform 1, through which the vehicle can enter the trailer platform 1. The sliding mechanism includes: a second motor 10, which is fixedly installed inside one end of the trailer platform 1 away from the mounting base 17. A lead screw 11 is rotatably installed inside the trailer platform 1, and one end of the lead screw 11 is connected to the output end of the second motor 10. A transverse sliding frame 12 is slidably installed at one end of the trailer platform 1 close to the second motor 10. The outer surface of the transverse sliding frame 12 is penetrated by the lead screw 11, and the lead screw 11 is in threaded connection with the transverse sliding frame 12. One end of the transverse sliding frame 12 away from the second motor 10 is rotatably installed with a support bridge 13, and the outer surface of the support bridge 13 is attached to the inner surface of the trailer platform 1.

[0034] When the second motor 10 rotates, it will drive the lead screw 11 to rotate. The rotation of the lead screw 11 drives the transverse sliding frame 12 to move, pushing the support bridge 13 out of the inside of the trailer platform 1, so that the support bridge 13 rotates and falls to contact the ground, which is convenient for the vehicle to enter the trailer platform 1. At the same time, it saves the use space of the trailer platform 1 and facilitates the storage of the support bridge 13.

[0035] The inside of the trailer platform 1 is provided with a linkage mechanism. By raising the linkage mechanism, the vehicle is blocked. The linkage mechanism includes: a slider 14. The outer surface of the slider 14 is penetrated by a lead screw 11, and the two ends of the lead screw 11 have opposite threads. The lead screw 11 is threadedly connected to the slider 14, and connecting rods 16 are rotatably installed on both sides of the slider 14. A shielding flat plate 15 is rotatably installed on one side of the trailer platform 1 close to the second motor 10, and the outer surface of the shielding flat plate 15 is connected to one end of the connecting rod 16, and the connecting rod 16 is rotatably connected to the shielding flat plate 15.

[0036] When the second motor 10 rotates to drive the rotation of the lead screw 11, the slider 14 will be driven to move, causing the slider 14 to move in the opposite direction to the transverse sliding frame 12. When the support bridge 13 is pushed out, the slider 14 will move towards the first motor 8, pulling the connecting rod 16 to lower the shielding flat plate 15 to facilitate the vehicle to get on and off. When the second motor 10 rotates in the reverse direction, the transverse sliding frame 12 will pull the support bridge 13 back. At the same time, the slider 14 moves away from the moving mounting base 17, pushing the connecting rod 16 to lift the shielding flat plate 15 to prevent the vehicle from sliding off the trailer platform 1 due to inertia and other factors. When the support bridge 13 is lowered, the shielding flat plate 15 descends, and when the support bridge 13 is retracted, the shielding flat plate 15 rises.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
