[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-5 As shown, this utility model provides a omnidirectional horizontal adjustment structure for a dump semi-trailer, including a vehicle body 1, which is a dump semi-trailer. An adjustment device 2 is installed at the bottom rear of the vehicle body 1. The adjustment device 2 includes a universal joint 22, which is fixedly installed on the vehicle body 1. A hydraulic rod 21 is hinged to the universal joint 22. A winch 3 is rotatably installed at the bottom rear of the vehicle body 1, with a steel cable 4 wound around it. A hook 12 is fixedly installed at one end of the steel cable 4. A second fixing ring 26 and a first fixing ring 25, distributed vertically, are fixedly installed on one side of the hydraulic rod 21, and the hook 12 can be hung on the first fixing ring 25. A large gear 13 is rotatably installed at one end of the winch 3, and the large gear 13 is fixedly connected to one end of the winch 3's shaft. A small gear 14 is rotatably installed at one end of the winch 3, and the small gear 14 meshes with the large gear 13. A crank handle 5 is rotatably installed at the bottom rear of the vehicle body 1, and one end of the crank handle 5 is fixedly connected to the small gear 14. When the cargo box of a dump semi-trailer cannot turn normally on sharp bends and narrow roads, the rear of the dump semi-trailer can be lifted by the hydraulic rod 21 and offset by the universal joint 22, thereby assisting the cargo box to move in all directions. After the adjustment device 2 is used, the hook 12 on the steel cable 4 is first hung on the first fixing ring 25 on the hydraulic rod 21. Then, the crank handle 5 drives the small gear 14 to rotate, the small gear 14 drives the large gear 13 to rotate, and the large gear 13 drives the winch 3 to rotate. The winch 3 winds up the steel cable 4. According to the mechanical structure, it is easier for the small gear 14 to drive the large gear 13 to rotate. The steel cable 4 drives the adjustment device 2 to flip through the hook 12, thereby realizing the purpose of storing the adjustment device 2 at the rear of the vehicle body 1. This prevents the bottom of the horizontal adjustment device 2 from contacting the ground during vehicle operation and causing damage to the device. It replaces the traditional method of manually storing the adjustment device 2, saving time and effort and increasing efficiency.

[0021] The bottom end of the hydraulic rod 21 is hingedly installed with a support plate 23, and the lower surface of the support plate 23 is fixedly installed with a plurality of bevel gears 24 arranged in an array.

[0022] By adopting the above technical scheme, the bevel gears 24 on the support plate 23 are inserted into the ground by the hydraulic rod 21 driving the support plate 23 to contact the ground, so that the stability is increased.

[0023] The bottom end of the vehicle body 1 is fixedly installed with a fixed frame 6, and the second fixing ring 26 can be inserted into the fixed frame 6. The fixed frame 6 is movably inserted with a bolt 7, and the bolt 7 can be inserted into the second fixing ring 26. One end of the bolt 7 is threadedly sleeved with a locking nut 8.

[0024] By adopting the above technical scheme, the second fixing ring 26 on the hydraulic rod 21 is inserted into the fixed frame 6 and the bolt 7 by the steel cable 4 driving the adjusting device 2 to overturn through the hook 12, and the locking nut 8 is tightened to limit and fix the adjusting device 2, so that the adjusting device 2 is prevented from falling off during vehicle driving.

[0025] The ratchet wheel 9 is fixedly installed on the handle 5, the car body 1 is hingedly installed with the pin 10, and the pin 10 can be engaged with the tooth groove of the ratchet wheel 9. The spring 11 is hung on the car body 1, and one end of the spring 11 is hung on the pin 10.

[0026] By adopting the above technical scheme, the ratchet wheel 9 cooperates with the pin 10 to prevent the winch 3 from being reversed during winding, so that the adjusting device 2 is prevented from falling off. When it is needed to unwind, the pin 10 can be manually pushed to disengage the pin 10 from the ratchet wheel 9, so that the winch 3 can be unwound. The spring 11 can always engage the pin 10 with the ratchet wheel 9.

[0027] Working principle: when the self-unloading semitrailer cannot normally turn in the case of sharp curve narrow road condition, the hydraulic rod 21 can be used to lift the tail part of the self-unloading semitrailer, and the universal head 22 is used to offset it, so as to assist the container to move universally, when the adjusting device 2 is used, first, the hook 12 on the steel cable 4 is hung on the first fixed ring 25 on the hydraulic rod 21, then the ratchet handle 5 is used to drive the pinion 14 to rotate, the pinion 14 drives the gear wheel 13 to rotate, the gear wheel 13 drives the winch 3 to rotate, the winch 3 winds the steel cable 4, the ratchet wheel 9 cooperates with the snap pin 10 to prevent the winch 3 from reversing during winding, so that the adjusting device 2 falls off, the steel cable 4 is used to drive the adjusting device 2 to overturn through the hook 12, the second fixed ring 26 on the hydraulic rod 21 is inserted into the fixed frame 6 and the bolt 7, and the lock nut 8 is tightened, so that the adjusting device 2 is limited and fixed, and the adjusting device 2 is prevented from falling off during vehicle driving, so that the adjusting device 2 is stored in the tail part of the vehicle body 1, the bottom of the horizontal adjusting device 2 is prevented from contacting the ground during vehicle driving, and the device is damaged, the traditional manual storage mode of the adjusting device 2 is replaced, time and labor are saved, and the efficiency is high.

[0028] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model belong to the scope of the utility model claims and equivalent technologies, the utility model also intends to include these modifications and variations.
