The positioning plate 10 is mutually extruded with the rollers 18 in a V-shaped guide way, so that the vehicle body 3 moves back and forth to be aligned in the tunnel. Then the first oil cylinder 15 is started, and the first oil cylinder 15 drives the supporting plate 17 to tightly prop against the backing plate 12, so that the driving wheel 4, the first driven wheel 5 and the second impulse wheel are suspended, and the situation that the vehicle body 3 is pushed by external force to slide in the track is reduced.

The implementation principle of the connection device for the RGV trolley track provided by the embodiment of the application is as follows: when there is an RGV trolley to move from one side of the tunnel to the other, the drive mechanism 7 drives the drive wheel 4 to roll, thereby bringing the vehicle body 3 into the docking area 11.

During the entry of the vehicle body 3 into the docking area 11, the second driven wheel 6 presses against the first guide bar 13 and the second guide bar 14, thereby aligning the vehicle body 3 after moving left and right. Then, the second oil cylinder 16 is started, and the second oil cylinder 16 drives the roller 18 to abut against the positioning plate 10, so that the vehicle body 3 moves forwards and backwards and is aligned. And then the first oil cylinder 15 is started, and the first oil cylinder 15 drives the vehicle body 3 to move upwards, so that the connection track 19 is butted with RGV trolley tracks on two sides of the tunnel, and the RGV trolley can conveniently move from one side of the tunnel to the other side.

When the gantry crane moves along the tunnel, the vehicle body 3 moves inside the tunnel to avoid the gantry crane. Meanwhile, when the vehicle body 3 moves in the tunnel, the rail of the RGV trolley does not obstruct the movement of the vehicle body 3, so that the vehicle body 3 can conveniently move the connection rail 19 to RGV rails on two sides of the tunnel, and the RGV trolley can conveniently move from one side of the tunnel to the other side.

Referring to fig. 10, 11 and 15, there are a plurality of push plates 242, and one push plate 242 is located between two adjacent slide bars 241 of different sub-rails 191. The push plate 242 is provided with two second sliding openings 27 for sliding the sliding rod 241. The two second sliding openings 27 positioned on the same push plate 242 are gradually arranged in an inclined way from one end to the other end. Pushing the push plate 242 to move in a direction perpendicular to the length of the docking track 19, thereby sliding the slide bar 241 inside the second slide port 27. The second sliding opening 27 is inclined to guide, so that the distance between two adjacent sub-rails 191 is adjusted, and the length of the connecting rail 19 is adjusted.

Referring to fig. 14, the stopper 28 abuts against the bottom surface of the push plate 242, and the top surface of the push plate 242 abuts against the inner top wall of the accommodating chamber 25, thereby reducing the occurrence of the upward and downward movement of the vibration belt mover rail 191 of the vehicle body 3.

Referring to fig. 10, the moving assembly 243 includes a stiffener 2431, a telescopic cylinder 2432, and a slot 2433. The groove 2433 is located inside the accommodating chamber 25, and the push plates 242 located inside the same accommodating chamber 25 are all located inside the groove 2433. Both inner side walls of the groove 2433 are abutted against the side walls of the push plate 242.

The reinforcing rods 2431 are multiple, and the reinforcing rods 2431 are uniformly distributed on two outer side walls of the groove 2433. One end of the reinforcing rod 2431 is fixedly connected with the outer side wall of the groove 2433, and the other end of the reinforcing rod 2431 is telescopically inserted into the inner side wall of the accommodating cavity 25. The cylinder body of the telescopic cylinder 2432 is fixedly embedded in the inner side wall of the accommodating cavity 25, and a piston rod of the telescopic cylinder 2432 is fixedly connected with the outer side wall of the groove 2433. The telescopic cylinder 2432 is telescopic in a direction perpendicular to the length direction of the docking rail 19. The telescopic cylinder 2432 drives the groove 2433 to move, and then the groove 2433 pushes the push plate 242 to move, so that the distance between adjacent sub-tracks 191 can be conveniently adjusted.

The implementation principle of the connection device for the RGV trolley track provided by the embodiment of the application is as follows: after the vehicle body 3 is stopped at the docking area 11, the vehicle body 3 is lifted up by the first cylinder 15 and the support plate 17. The telescopic cylinder 2432 is started, and the telescopic cylinder 2432 drives the groove 2433 to push each push plate 242 to move, so that the slide rod 241 slides in the second slide opening 27, and the distance between two adjacent sub-tracks 191 is increased. By increasing the spacing between adjacent two sub-tracks 191, the length of the docking track 19 is increased. The docking rail 19 would then interface with the RGV trolley rails on both sides of the tunnel.

After the docking rail 19 is docked with the RGV trolley rails on both sides of the tunnel, the RGV trolley moves on the docking rail 19, thereby increasing the weight of the vehicle body 3. The gravity of the vehicle body 3 increases to squeeze the first oil cylinder 15, so that the vehicle body 3 descends, and the two ends of the connecting track 19 are driven to press on the ground on the two sides of the tunnel. The two ends of the refuting track are pressed on the ground at two sides of the tunnel to carry out component force, so that the situation that the RGV trolley crushes the vehicle body 3 and the first oil cylinder 15 is reduced. By dividing the docking rail 19 into a plurality of sub-rails 191, the spacing between two adjacent sub-rails 191 after being separated from each other is small, thereby facilitating movement of the RGV trolley on the docking rail 19.

After the RGV trolley moves from one side of the tunnel to the other side, the telescopic cylinder 2432 drives the groove 2433 to return, so that each sub-rail 191 is close to each other, the length of the connecting rail 19 is reduced, and the length of the connecting rail 19 is smaller than the width of the tunnel. And then the oil cylinder descends to enable the driving wheel 4 and the first driven wheel 5 to be abutted against the track again, and the top side of the second guide rail 2 enters the inside of the annular groove 9. The driving mechanism 7 starts the driving wheel 4 to drive the vehicle body 3 to drive away from the connection area 11.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
