For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] It should be noted that the directional words such as "up, down, left, right" etc. mentioned below are defined based on the drawings in the specification.

[0053] The core of the utility model is to provide a roller replacement trolley for a squeeze roller and a brush roller, which can replace the squeeze roller and the brush roller faster, easier and more labor-saving, and has simple operation and short time consumption.

[0054] Please refer to Figure 1 A roller changing trolley for squeezing rollers and brush rollers comprises a moving body 1, a counterweight device 2, a clamping head 3, a clamping head adjusting device 4 and an electrical remote control device.

[0055] Specifically, the mobile body 1 and the first mobile component are connected to the electrical remote control device, and the operating state of the mobile body 1 is controlled by the electrical remote control device. The counterweight device 2 is detachably arranged in the fixed frame 11 of the mobile body 1. The counterweight devices 2 of different weights can be replaced according to the weight of different rollers to balance the center of gravity of the roller-changing trolley when carrying rollers, so as to make the weight distribution more balanced.

[0056] The clamping head 3 is arranged on the mobile body 1 through the clamping head adjusting device 4. The clamping head adjusting device 4 includes a first movable component and a second movable component. The first movable component is arranged on the mobile body 1 and is used to adjust the up and down movement of the clamping head 3. The second movable component is connected to the first movable component. The second movable component is used to adjust the left and right swing of the clamping head 3. Through the cooperation of the first movable component and the second movable component, the up and down, left and right adjustment of the clamping head 3 can be realized so that the clamping head 3 is aligned and clamped with the roller to be replaced.

[0057] When the roller of the equipment needs to be replaced, the mobile body 1 is controlled by the electrical remote control device to travel until the clamping head 3 is about to contact the roller to be replaced and stops. The clamping head 3 is adjusted up, down, left and right through the cooperation of the first moving component and the second moving component until the clamping head 3 firmly clamps the shaft head of the roller to be replaced. The mobile body 1 is controlled to retreat and transfer the disassembled roller to the storage place. With the cooperation of the roller changing trolley, the roller can be replaced quickly and conveniently.

[0058] Among them, a counterweight device 2 is provided at the rear of the mobile car body 1. Each counterweight weighs 35Kg and is composed of 24 pieces to balance the center of gravity of the mobile car. The weight of the counterweight device 2 is obtained through repeated verification and simulation analysis to make the weight distribution of the mobile car more balanced when carrying a 0.7T roller.

[0059] The roller changing trolley for the squeeze roller and the brush roller arranged in the above manner is driven and remotely controlled by an electrical remote control device to move the roller changing trolley forward and backward, and the chuck adjustment device 4 is used to adjust the chuck 3 so that its upper, lower, left and right positions are clamped with the shaft heads of the squeeze roller and the brush roller to be replaced, and then the rollers are pushed in and pulled out to complete the replacement. The entire roller changing process is quick and simple.

[0060] In the above embodiment, the first moving component includes a column 41, a moving frame 42 and a first worm gear lift 43. The column 41 is vertically arranged on the moving body 1 and extends along the height direction of the moving body 1. The moving frame 42 is sleeved on the outer periphery of the column 41 and is movable along the height direction of the column 41. The first worm gear lift 43 is a vertical structure and is arranged on the moving body 1. The output end of the first worm gear lift 43 is lifted and moved along the height direction of the column 41. The output end of the first worm gear lift 43 is provided with a top block abutting against the moving frame 42.

[0061] It should be noted that, when the chuck 3 needs to be adjusted upward, the first worm gear lift 43 is controlled to operate by a hand wheel to make the first worm gear lift 43 rise, and at the same time drive the top block to rise, so that the top block abuts against the movable frame 42, and the movable frame 42 is raised along the column 41 to the position where the chuck 3 is flush with the roller. When the chuck 3 needs to be adjusted downward, the first worm gear lift 43 is controlled to operate by a hand wheel to make the first worm gear lift 43 descend, and at the same time drive the top block to descend. The movable frame 42 is originally supported by the top block. When the top block moves downward, the movable frame 42 loses support and moves downward with the top block until the chuck 3 on the movable frame 42 is flush with the roller.

[0062] The rise and fall of the first worm gear elevator 43 is adjusted by the forward and reverse rotation of the hand wheel.

[0063] Please refer to Figure 5The mobile frame 42 is a rectangular cylindrical structure. Two groups of rolling devices extending along the height direction of the column 41 are arranged in the mobile frame 42. Any group of rolling devices includes two first rollers 44. The first rollers 44 are rotatably connected to the mobile frame 42 through rollers. The column 41 is provided with a slide rail that cooperates with the first rollers 44.

[0064] It can be understood that when the mobile frame 42 moves up and down along the column 41 driven by the first worm gear elevator 43, the first roller 44 provided on the mobile frame 42 moves along the slide rail on the column 41 to reduce the sliding friction between the mobile frame 42 and the column 41.

[0065] Among them, in this embodiment, the movement of the mobile frame 42 is achieved by setting a first roller 44 on the mobile frame 42 and setting a slide rail on the column 41. However, in actual applications, other methods can also be used to achieve the movement of the mobile frame 42. There is no limitation to this as long as the above-mentioned technical effects can be achieved.

[0066] Furthermore, the second moving component includes a swing frame 45 and a second worm gear elevator 48. The swing frame 45 is a U-shaped structure. The swing frame 45 is sleeved on one side of the moving frame 42, and a sufficient swing distance is left between the swing frame 45 and the moving frame 42. The upper end of the swing frame 45 is swingably connected to the moving frame 42 through a swing shaft 46. Both ends of the swing shaft 46 are provided with retaining rings 47. The lower end of the swing frame 45 is fixed to the moving frame 42 through an adjusting block 5 and an adjusting bolt 6. The second worm gear elevator 48 is a horizontal structure. The second worm gear elevator 48 is arranged on the swing frame 45. The output end of the second worm gear elevator 48 passes through the swing frame 45 and the moving frame 42. The output end of the second worm gear elevator 48 is fixed to the moving frame 42 through a positioning retaining ring and a locking nut.

[0067] It should be noted that when the chuck 3 needs to be adjusted to swing left and right, the second worm gear lift 48 is driven by the forward rotation of the hand wheel, so that the output end of the second worm gear lift 48 extends to the right until it abuts against the swing frame 45, and the swing frame 45 swings to the left along the swing shaft 46, and the second worm gear lift 48 is driven by the reverse rotation of the hand wheel, so that the output end of the second worm gear lift 48 is retracted to the left to remove the force of the second worm gear lift 48 on the swing frame 45 to push to the right, so that the swing frame 45 swings to the right, and the chuck 3 on the swing frame 45 is adjusted to complete the left and right swing adjustment, so that the chuck 3 is aligned with the roller.

[0068] Among them, the extension and retraction of the second worm gear lift 48 are adjusted by the forward and reverse rotation of the handwheel. Specifically, the output end of the second worm gear lift 48 can be retracted by the forward rotation of the handwheel, and the output end of the second worm gear lift 48 can be extended by the reverse rotation of the handwheel. There is no limitation to this as long as the above-mentioned technical effect can be achieved.

[0069] That is to say, the clamping head 3 is located in front of the swing frame 45, and the clamping head 3 is swung left and right with a swing frame 45. The left and right movements are completed by a horizontally arranged second worm gear lift 48, and then the angle of the clamping head 3 is fine-tuned by the adjusting bolt 6 and the adjusting block 5 arranged below the clamping head 3, so that it is easier to connect the squeeze roller and brush roller shaft head to be replaced. The clamping head 3 is moved up and down with a moving frame 42, and four first rollers 44 are distributed in the moving frame 42. The moving frame 42 completes the up and down movement along the column 41 through the vertically arranged first worm gear lift 43.

[0070] Among them, the up, down, left and right adjustments of the clamping head 3 are all completed by the worm gear elevator, which has strong reliability, large bearing capacity, convenient installation, no noise and long service life.
