By setting the auxiliary structure 4, personnel can easily replace the worn rubber pad 302, thereby avoiding the worn rubber pad 302 from affecting the normal use of the locking structure 3, and improving the service life of the locking device. The side of the adjusting ring 45 close to the partition 41 is fixedly connected with a pad The gasket 46 is specifically made of rubber material.

[0037] The working principle of a transfer vehicle locking device provided by the utility model is as follows: when the transfer vehicle is needed to transfer the steel coil, the steel coil is first placed on the support arm 2, and then the motor 5 is started to drive the driving gear 6 to rotate, the driving gear 6 drives the chain 7 to rotate, and at the same time the chain 7 drives the driven gear 9 to rotate, and the driven gear 9 drives the rotating shaft 8 and the wheel 10 to rotate, so that the device transfers the steel coil during the rotation of the wheel 10. When the transfer vehicle drives the steel coil to the designated position, the operation of the motor 5 can be stopped. However, at this time, the wheel 10 will continue to rotate due to inertia, which will cause the transfer destination of the steel coil to shift. Therefore, it is necessary to use the locking structure 3 to lock and limit the wheel 10. The specific steps are: start the cylinder 308 to drive the connecting plate 309 to move, the connecting plate 309 drives the connecting plate 306, the connecting plate 306 drives the turntable 305 to rotate, and the turntable 305 drives the limiting plate 304 to make the limiting plate 304 rotate along the inner wall of the fixed seat 303. When one side of the limiting plate 304 is in contact with the rubber on the locking plate 301 After the pad 302 abuts, the locking plate 301 can be locked and limited, and then the rotating disk 305 and the wheel 10 can be locked and limited. When the wheel 10 is needed to drive the frame 1 to move, it is only necessary to start the cylinder 308 to drive the connecting plate 309 to move in the opposite direction. At this time, the limiting plate 304 will rotate in the opposite direction. When the limiting plate 304 is separated from the rubber pad 302 on the locking plate 301, the limit of the wheel 10 can be released. In the process of the locking plate 301 rotating, the sliding plate 312 will move along the locking plate The inner wall of the annular hole 313 on 301 slides, thereby achieving the effect of improving the stability of the locking disk 301 during rotation. In addition, by providing a plurality of anti-slip grooves 314 on one side of the rubber pad 302, the friction between the rubber pad 302 and the limit plate 304 can be further increased. Finally, when the cylinder 308 drives the connecting plate 309 to move, the positioning plate 310 fixed on the connecting plate 309 will move along the arc surface of the positioning rod 311, thereby achieving the effect of improving the stability of the connecting plate 309 during movement.

[0038] The rubber pad 302 will wear out after being used for a period of time. When the worn rubber pad 302 needs to be replaced, the adjusting ring 45 is first rotated to move along the arc surface of the slide rod 44. After the adjusting ring 45 drives the gasket 46 to separate from the slide rod 44, the rubber pad 302 is moved to drive the partition 41, and the partition 41 drives the sliding hole 42 to separate the sliding hole 42 from the slide rod 44. At the same time, the positioning block 47 on one side of the rubber pad 302 is separated from the positioning hole 48. At this time, the removal of the rubber pad 302 is completed. When the rubber pad 302 needs to be installed, the rubber pad 302 is first moved to drive the partition 41, and the slide rod 44 is inserted into the sliding hole 42 on the partition 41. Insert the positioning block 47 fixed on the rubber pad 302 into the positioning hole 48, then put the adjusting ring 45 on the arc surface of the slide rod 44, and then rotate the adjusting ring 45 to drive the gasket 46 to abut against the partition 41, and the installation of the rubber pad 302 can be completed. Among them, the gasket 46 can increase the friction force of the adjusting ring 45 close to the side of the partition 41, so that the adjusting ring 45 can be firmly abutted against the partition 41 with the help of the gasket 46. In addition, when installing the rubber pad 302, the positioning block 47 fixed on the rubber pad 302 is inserted into the positioning hole 48 on the locking disk 301, so that the rubber pad 302 can be fixed more firmly.
