A hexagonal hole matching the hexagonal shaft 15 is opened inside the fixed sleeve 18, and a screw rod 13 is rotatably installed between the inner walls at the opposite ends of the trapezoidal slide groove 11, and one end of the screw rod 13 penetrates the outer surface of the base 1 and is fixedly installed with a knob 14, the screw rod 13 penetrates the outer surface of the trapezoidal slider 12 and is threadedly connected thereto, and the fixed sleeve 18 and the mounting plate are rotatably installed through a bearing.

[0026] The screw rod 13 is driven to rotate by the knob 14, so that the screw rod 13 drives the trapezoidal slider 12 to slide in the direction close to the knob 14, and the trapezoidal slider 12 drives the mounting plate to slide, so that the mounting plate drives the rotating plate 2 to move away from the pinch roller 7 through the fixed sleeve 18, and the rotating sleeve 8 moves away from the pinch roller 7. At this time, the pinch roller 7 is released from the limit, and the operator can remove the two pinch rollers 7, replace them with new pinch rollers 7, and then rotate the knob 14 in the opposite direction to re-position the pinch roller 7. When the device is used to disassemble and assemble the pinch roller 7, there is no need to use lifting equipment for assistance, which avoids the problem of small space in the factory or obstruction by other equipment, and reduces the difficulty of disassembling and assembling the pinch roller 7.

[0027] In this embodiment, two positioning rods 19 are symmetrically inserted into the upper surface of the trapezoidal slider 12, and a retaining ring 20 is fixedly installed on the top of the two positioning rods 19. A spring 21 is sleeved on the outer surface of the positioning rod 19 near the top, and the two ends of the spring 21 are respectively fixedly installed on the retaining ring 20 and the outer surface of the trapezoidal slider 12. The positioning rod 19 passes through the lower surface of the trapezoidal slider 12 and is slidably installed therewith. A positioning hole matching the positioning rod 19 is opened on the bottom wall of the trapezoidal slide groove 11, and two protrusions 16 are fixedly installed on the lower surface of the rotating plate 2 near the retaining ring 20, and the protrusions 16 are against the upper surface of the retaining ring 20.

[0028] The rotating plate 2 drives the two clamping rollers 7 to move to the upper surface of the moving vehicle below. Through the movement of the rotating plate 2, the two protrusions 16 leave the retaining ring 20, and the positioning rod 19 leaves the positioning hole due to the force of the spring 21. At this time, the trapezoidal slider 12 is released from the limit. This device is used to limit the position of the trapezoidal slider 12 to avoid its position displacement during use.

[0029] In this embodiment, a support 5 is fixedly installed on the side of the base 1 away from one end of the trapezoidal slider 12, and a hydraulic telescopic rod 6 is rotatably installed on the inner wall of the support 5. The telescopic end of the hydraulic telescopic rod 6 is rotatably installed on the outer surface of the adjacent rotating plate 2. The outer surfaces of the two rotating plates 2 are aligned up and down and two rotating sleeves 8 are rotatably installed. A hexagonal through hole is opened inside the rotating sleeve 8, and a clamping roller 7 is arranged between the two rotating sleeves 8. Hexagonal columns are fixedly installed on both ends of the clamping roller 7, and the hexagonal columns are slidably installed on the inner walls of the hexagonal through holes.

[0030] When it is necessary to disassemble and assemble the pinch roller 7, the retracting movement of the hydraulic telescopic rod 6 drives the rotating plate 2 to rotate downward, and the rotating plate 2 drives the rotating shaft 17 to rotate, so that the rotating shaft 17 drives the hexagonal shaft 15 to rotate, and the hexagonal shaft 15 drives the other rotating plate 2 to rotate downward through the hexagonal hole inside the fixed sleeve 18. When the rotating plate 2 is completely rotated to the bottom, at this time, the rotating plate 2 drives the two pinch rollers 7 to move to the upper surface of the moving vehicle below.

[0031] In this embodiment, one end of the two rotating sleeves 8 away from the trapezoidal slider 12 passes through the outer surface of the rotating plate 2 and is fixedly installed with a gear 9, and the two gears 9 are meshed with each other. A driving motor 4 is fixedly installed on the upper surface of the base 1, and a driving gear 10 is fixedly installed on the output end of the driving motor 4. The driving gear 10 is meshed with one of the gears 9, and the driving gear 10 and the rotating shaft 17 are arranged on the same axis. The same axis arrangement facilitates the driving gear 10 to rotate around the outer ring of the gear 9.

[0032] When in use, the driving motor 4 drives the driving gear 10 to rotate, so that the driving gear 10 drives one of the gears 9 to rotate, and the gear 9 drives the other gear 9 to rotate. The two gears 9 drive the two rotating sleeves 8 to rotate through the hexagonal columns and the hexagonal through holes, so that the two rotating sleeves 8 drive the two pinch rollers 7 to rotate in the opposite direction. The steel plate in the middle can be rolled through the rotation of the two pinch rollers 7.

[0033] It should be noted that when the utility model is in use, the driving motor 4 drives the driving gear 10 to rotate, so that the driving gear 10 drives one of the gears 9 to rotate, and the gear 9 drives the other gear 9 to rotate, and the two gears 9 drive the two rotating sleeves 8 to rotate through the hexagonal prism and the hexagonal through hole, so that the two rotating sleeves 8 drive the two pinch rollers 7 to rotate in the opposite direction, and the steel plate in the middle can be rolled through the rotation of the two pinch rollers 7; when it is necessary to disassemble the pinch rollers 7, the retraction movement of the hydraulic telescopic rod 6 drives the rotating plate 2 to rotate downward, and the rotating plate 2 drives the rotating shaft 17 to rotate, so that the rotating shaft 17 drives the hexagonal shaft 15 to rotate, and the hexagonal shaft 15 drives the other rotating plate 2 to rotate downward through the hexagonal hole inside the fixed sleeve 18. When the rotating plate 2 is completely rotated to the bottom, at this time, the rotating plate 2 drives the two pinch rollers 7 to move to the upper surface of the moving vehicle below, and through the rotating plate 2 Movement causes the two protrusions 16 to leave the retaining ring 20, and the positioning rod 19 leaves the positioning hole due to the force of the spring 21. At this time, the trapezoidal slider 12 is released from the limit, and the user manually turns the knob 14, and the knob 14 drives the screw rod 13 to rotate, so that the screw rod 13 drives the trapezoidal slider 12 to slide in the direction close to the knob 14, and the trapezoidal slider 12 drives the mounting plate to slide, so that the mounting plate drives the rotating plate 2 to move away from the pinch roller 7 through the fixed sleeve 18, and the rotating sleeve 8 moves away from the pinch roller 7. At this time, the pinch roller 7 is released from the limit, and the operator can remove the two pinch rollers 7, replace the new pinch roller 7, and then reversely rotate the knob 14 to re-position the pinch roller 7. When the pinch roller 7 is disassembled and assembled by using this device, there is no need to use lifting equipment for assistance, which avoids the problem of small space in the factory or obstruction by other equipment, and reduces the difficulty of disassembling and assembling the pinch roller 7.
