[0002] At present, there are various working rollers in the plate pickling line and degreasing line, which have different roles and functions in the system. The working surface of the roller is made of rubber. The design of the rubber material is to ensure that the surface of the plate is not scratched, to ensure product quality, and to realize the function of the working roller. This has caused many problems. The surface of the rubber roller will wear after long-term contact with the metal plate. The performance of the rubber material will change when the roller is in contact with the liquid for a long time. The roller needs to be replaced regularly or according to the actual situation, which requires a roller replacement tool.

The connecting block 408 drives the guide rod 407 to move upward in the guide ring 406. Since the transverse walking wheel 5 is in contact with the transverse track 701 at this time, the frame 1 moves downward at this time, and the frame 1 drives the longitudinal walking wheel 2 to move downward until the longitudinal walking wheel 2 is in contact with the longitudinal track 702. At this time, as the first hydraulic cylinder 405 continues to work, the guide rod 407 drives the transverse walking wheel 5 to move upward, and finally the transverse walking wheel 5 is out of contact with the transverse track 701. At this time, turn off the hydraulic pump 302. Then, the frame 1 is pushed, and the frame 1 moves on the longitudinal track 702 through the longitudinal running wheel 2 until the frame 1 moves to the position of the roller to be replaced, and the transverse running wheel 5 is facing the corresponding transverse track 701. At this time, the first turntable 610 is rotated, and the first turntable 610 drives the rotating shaft 609 to move, the rotating shaft 609 drives the internal threaded cylinder 608 to move, and the internal threaded cylinder 608 drives the clamping plate 606 to move, so that the two clamping plates 606 are close to each other, until the longitudinal track 702 is in close contact with the inner walls of the two limiting grooves 607, and the fixing work of the frame 1 is completed at this time; At this time, the first motor 905 is started, and the first motor 905 drives the double sprocket 907 to rotate through the reducer 906. Since the double sprocket 907 is meshed with the double-row roller chain 10, the double sprocket 907 moves on the double-row roller chain 10, thereby driving the roller-changing moving frame 9 to move on the two slides 8; When the mounting frame 12 approaches the roller that needs to be replaced, first turn off the first motor 905, and then determine whether the stick can be normally inserted into the guide hole 1402. If it can be normally inserted into the guide hole 1402, just continue to start the first motor 905 to make the mounting frame 12 continue to approach the roller that needs to be replaced until the roller is successfully inserted into the guide hole 1402 and contacts the mounting frame 12. At this time, turn off the first motor 905, and then inject fluid into the second hydraulic cylinder 1403 through the manual hydraulic pump 1503. At this time, the output shaft of the second hydraulic cylinder 1403 pushes the clamping block 1408 to move downward until the clamping block 1408 and the guide block 1401 clamp the roller. At this time, the clamping work of the roller that needs to be replaced is completed; If the roller to be replaced cannot be normally inserted into the guide hole 1402, it is only necessary to rotate the second rotary disk 1304, and the second rotary disk 1304 drives the first fine-tuning screw 1301 to rotate in the fine-tuning threaded tube 1302, and the first fine-tuning screw 1301 drives the mounting frame 12 to move, and the mounting frame 12 drives the guide hole 1402 to move until the guide hole 1402 is facing the roller to be replaced. At this time, the stick to be replaced can be clamped according to the above operation; Then start the second motor 1104, the second motor 1104 pushes the lifting frame 1107 to move up on the outside of the guide column 1103 through the worm lifting mechanism 1105, the lifting frame 1107 drives the mounting frame 12 to move upward, the mounting frame 12 drives the clamping mechanism 14 to move, the clamping mechanism 14 drives the clamped roller to move upward, so that the roller to be replaced can be moved to the top of the production line, the second motor 1104 is started in reverse to reset the roller changing moving frame 9, at this time the disassembled roller is removed from the top of the production line, at this time the first turntable 610 is rotated in reverse to make the two clamping plates 606 disengage from the longitudinal track 702, at this time the frame 1 can be pushed to make the frame 1 move the disassembled roller to one end of the production line on the two longitudinal walking wheels 2, and then after the disassembled roller is removed, a new roller is clamped again, and the new roller is replaced again according to the above operation to complete the roller replacement work; When, after the roller is lifted, the height deviation of the two ends of the roller is large, making it difficult to install the roller, the manual hydraulic pump 1503 is used to inject liquid into the third hydraulic cylinder 1601. At this time, the third hydraulic cylinder 1601 can push the installation frame 1201 to rotate around the connecting rod 1202, thereby adjusting the height of the two ends of the roller, so that the roller is relatively level until the roller can be installed on the production line.

In conjunction with the walking beam 7 composed of the transverse track 701 and the longitudinal track 702, the roller changing vehicle can be moved transversely and longitudinally in a small space without turning.

In addition, through the setting of the slide plate 8, a stronger support can be provided for the roller changing mobile frame 9, so that the working intensity of the double-row roller chain 10 and the double sprocket 907 can be reduced, so that the roller changing mobile frame 9 can move more smoothly; through the mounting plate 1101, the fixing frame 1102, the guide column 1103, the second motor 1104, the worm lifting mechanism 1105, the second articulated seat 1106, and the lifting frame 1107 The lifting mechanism 11 composed of the guide roller 1108 can utilize the working mechanism of the worm gear and the worm to more stably lift the lifting frame 1107; the lateral fine-tuning mechanism 13 composed of the first fine-tuning screw 1301, the fine-tuning threaded tube 1302, the rotating sleeve 1303 and the second turntable 1304 can be installed on the mounting frame 12 to perform horizontal fine-tuning through the clamping mechanism 14, so as to facilitate the clamping of the roller; the angle fine-tuning mechanism 16 composed of the third hydraulic cylinder 1601, the second articulated shaft 1602 and the rotating seat 1603 can adjust the height of the two ends of the roller, so as to facilitate the replacement of the roller.
