DETAILED DESCRIPTION

[0026] 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.

[0027] Example

[0028] Reference Figure 1-6 As shown, a coal mine car cargo box connection mechanism includes a car cargo box body 1, two groups of moving plates 212, moving wheels 213 rotatably connected to the inner wall of the moving plate 212, and four groups of horizontal plates 211 installed on the top of the moving plate 212.

[0029] A plug rod 311 is fixed to the bottom of the main body 1 of the mine car cargo box, and a plug hole 312 corresponding to the plug rod 311 is provided inside the cross plate 211. A limit mechanism for limiting the disengagement of the plug rod 311 from the plug hole 312 is provided at the bottom of the main body 1 of the mine car cargo box. After the plug rod 311 is inserted into the plug hole 312, a good positioning effect can be achieved, and a stable locking effect can be achieved. A guide rod 315 is fixed to the outer wall of the cross plate 211, and a rack plate 313 is sleeved on the outer wall of the guide rod 315. A slot 314 corresponding to the rack plate 313 is provided inside the cross plate 211 and the plug rod 311. The rack plate 313 can slide along the outer wall of the guide rod 315, and the rack plate 313 can be inserted into the slot 314 to lock the main body 1 of the mine car cargo box and the cross plate 211. A telescopic spring 316 is wound around the outer wall of the guide rod 315 , one end of the telescopic spring 316 is connected to the rack plate 313 , and the other end is connected to the cross plate 211 . The elasticity of the telescopic spring 316 drives the rack plate 313 to rebound, and the rack plate 313 is stably inserted into the slot 314 .

[0030] Two sets of rotating rods 317 are rotatably connected at the bottom end of the mine car cargo box body 1, and handles 319 are fixed to the bottom ends of the two sets of rotating rods 317. The outer wall of the rotating rod 317 is fixed with a rotating gear 318 meshing with the rack plate 313. The two sets of rotating rods 317 are connected through a transmission mechanism. By rotating any set of handles 319, the two sets of rotating rods 317 and the two sets of rotating gears 318 can be rotated under the transmission mechanism. The rotating gear 318 drives the rack plate 313 to enter and exit the slot 314. This operation method is more efficient and saves time and effort.

[0031] The transmission mechanism includes a belt 321 and two sets of pulleys 320. The two sets of pulleys 320 are fixed to the outer wall of the rotating rod 317 and are connected through the belt 321. When the pulley 320 rotates, the belt 321 is transmitted and drives the other set of pulleys 320 to rotate, achieving a good transmission effect.

[0032] Both ends of the four groups of horizontal plates 211 and the top of the mobile plate 212 are provided with positioning screw holes 214, and the inner wall of the positioning screw hole 214 is threadedly connected with a positioning screw 215. The positioning screw 215 is threadedly connected with the positioning screw holes 214 at different positions, so that the position between the mobile plate 212 and the mine car cargo box body 1 can be adjusted, which is convenient for ensuring that the mine car cargo box body 1 will not be blocked during transportation, and has a good protective effect, avoiding the mine car cargo box body 1 from being damaged by contact. The outer wall of the positioning screw 215 is provided with a plurality of groups of anti-skid grooves 216, and the cross section of the anti-skid groove 216 is rectangular. The provision of the anti-skid groove 216 can achieve a good anti-skid effect, which is convenient for the staff to manually rotate the positioning screw 215, and ensures that the staff can operate more comfortably.

[0033] Working principle: When the cross plate 211 needs to be connected to the mine car cargo box body 1, first rotate any one set of handles 319 to drive the rotating rod 317 and the rotating gear 318 to rotate, and drive the other set of rotating rods 317 and the rotating gear 318 to rotate under the action of the transmission mechanism. The rotating gear 318 drives the two sets of rack plates 313 to move toward each other and drives the telescopic spring 316 to compress. Then, the insertion rod 311 at the bottom end of the mine car cargo box body 1 is inserted into the socket 312 inside the cross plate 211. After releasing the handle 319, the rack plate 313 is driven to be inserted into the slot 314 under the elasticity of the telescopic spring 316, thereby locking the mine car cargo box body 1 and the cross plate 211.

[0034] When the position of the mine car cargo box body 1 needs to be adjusted, the positioning screw 215 is rotated to disengage it from the inside of the positioning screw hole 214. After the movable plate 212 is moved to adjust to a different position, the positioning screw 215 is rotated again to lock the positioning screw hole 214 again, thereby achieving a good adjustment effect and facilitating the tilting unloading of the mine car cargo box body 1.

[0035] 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.
