Description

Technical Field

[0001] The utility model relates to the technical field of automatic unhooking devices, in particular to an automatic hooking and unhooking device for a cargo box of a mine car. Background Art

[0002] Mine cars are special vehicles for transporting minerals. In order to adapt to the narrow conditions of underground tunnels, they are compact in size and include trucks, man-carrying cars, material cars, etc. Mine cars are transport vehicles for transporting bulk materials such as ore, waste rock and coal in mines, and are generally towed by locomotives or winches. In addition to mine cars for transporting bulk materials, mining vehicles also include flatbed cars and material cars specially designed for transporting materials; inclined shaft man-carrying cars and horizontal tunnel man-carrying cars for passengers; and other special vehicles, such as explosives cars, water supply cars, fire trucks, and sanitary cars. The cargo box of a mine car is a box-shaped container for loading materials on a mine car.

[0003] During the connection process of the mine car cargo box, a hook is usually required for locking connection. During the connection process, the hook corresponds to the hole of the cargo box. When the mine car cargo box moves, it is easy to cause the hook and the hole to fall off, resulting in the problem that the connection between the mine car cargo box is not stable enough, resulting in the hook and the hole being loose and unhooked, and it is more laborious to manually support the hook.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example

[0027] Reference Figure 1-5 As shown, an automatic hooking and unhooking device for a mine car cargo box includes a mine car cargo box body 1 and a connecting plate 2 fixed to the outer wall of the mine car cargo box body 1, a hole 312 is opened inside the connecting plate 2, and a hook 311 is inserted into the hole 312.

[0028] Two groups of second fixing plates 320 are fixed on the top of the connecting plate 2, and the two groups of second fixing plates 320 are connected with a screw rod 322 for rotation relative to one side. A sliding groove 321 is installed on the outer wall of the second fixing plate 320 away from the hook 311, and the output end of the sliding groove 321 is connected to the screw rod 322. The outer wall of the screw rod 322 is threadedly connected with a threaded sleeve 318, and the outer wall of the threaded sleeve 318 is movably connected with a block 314 that slides with the top of the connecting plate 2. A slot 313 corresponding to the block 314 is provided on the outer wall of the hook 311. The screw rod 322 is driven to rotate by opening the sliding groove 321. Under the action of the thread, the threaded sleeve 318 can be driven to move horizontally, and the block 314 can be driven to enter and exit the slot 313, thereby realizing an automatic hanging and detaching effect. The outer wall of the threaded sleeve 318 is hinged with one end of an articulated rod 319, and the other end of the articulated rod 319 is hinged to the top of the block 314. The articulated rod 319 can achieve a good rotation effect. When the threaded sleeve 318 is used horizontally, it will drive the articulated rod 319 to rotate and push the block 314 in and out of the slot 313, so as to achieve the purpose of stable hooking and unhooking of the hook 311. The top of the connecting plate 2 is provided with a sliding groove 321, and the bottom of the threaded sleeve 318 is slidably connected with the sliding groove 321. The provision of the sliding groove 321 can ensure that the movement of the threaded sleeve 318 is sufficiently stable. The top of the connecting plate 2 is fixed with a first fixed plate 315, and the outer wall of the first fixed plate 315 is fixed with a guide rod 316. The side wall of the block 314 is provided with a guide hole 317 corresponding to the guide rod 316. The provision of the guide rod 316 and the guide hole 317 can ensure the stable movement effect of the block 314, and ensure that the block 314 can be inserted or detached corresponding to the slot 313.

[0029] A third fixing plate 413 is fixed to the top of the connecting plate 2, and a protective plate 411 is connected to the outer wall of the third fixing plate 413 through a telescopic mechanism. When the connecting plate 2 collides, the protective plate 411 can protect the automatic hooking and unhooking structure. A protective layer 412 is fixed to the side of the protective plate 411 away from the hook 311. The protective layer 412 is made of silicone and has good wear resistance and pressure resistance, ensuring that the protective plate 411 will not be damaged by contact.

[0030] The telescopic mechanism includes a fixed cylinder 414, a spring 415 and a movable rod 416. The fixed cylinder 414 is fixed to the outer wall of the third fixed plate 413. One end of the movable rod 416 is fixed to the protective plate 411 and the other end is inserted into the fixed cylinder 414. The movable rod 416 is connected to the inner wall of the fixed cylinder 414 through the spring 415. When the protective plate 411 is pressurized, the movable rod 416 is inserted into the fixed cylinder 414 and drives the spring 415 to compress. The spring 415 can achieve a better buffering effect, reduce the kinetic energy of the impact, and provide comprehensive protection for the above-mentioned automatic hooking and unhooking structure.

[0031] Working principle: When self-locking is required, the hook 311 is inserted into the hole 312, and the slot 313 is made to correspond to the block 314. The sliding slot 321 is opened to drive the screw rod 322 to rotate. Under the action of the thread, the threaded sleeve 318 is driven to slide horizontally on the sliding slot 321. The threaded sleeve 318 drives the hinge rod 319 to rotate and pushes the block 314 to be inserted into the slot 313. The block 314 moves stably under the action of the guide rod 316 and the guide hole 317 to achieve the effect of automatic locking.

[0032] When the protective layer 412 collides, it will move toward the third fixed plate 413 and drive the protective plate 411 to move. At this time, the movable rod 416 is inserted into the fixed tube 414, so that the spring 415 is squeezed and compressed, and the kinetic energy is converted into elastic potential energy, which has a buffering effect.

[0033] Although 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 appended claims and their equivalents.
