[0028] See Figure 1 , an embodiment of the present invention provides a multi-piece type roll skin disassembly device for a pair of rolls, including a roll shaft support member 1, a swinging jib 2, a connecting component, and a driving component. The roll shaft support member 1 is used to support the outer peripheral surface of the roll shaft of the pair of rolls, thereby establishing a load support system for disassembling the roll skin 3 of the pair of rolls. Among them, the roll shaft support member 1 extends a certain height along the radial direction of the roll shaft of the pair of rolls, and the height of the roll shaft support member 1 needs to be higher than the radial height of the roll skin 3 to be disassembled, so as to ensure that the swinging jib 2 can straddle the roll skin 3 to be disassembled and extend to the end of the roll skin 3 to be disassembled.

[0029] The swinging jib 2 extends from the first end 21 to the second end 22 along the length direction. A rotating shaft is provided at the first end 21. The swinging jib 2 is installed on the roll shaft support member 1 through the rotating shaft 23. The swinging jib 2 defines a rotation axis parallel to the tangential direction of the roll shaft of the pair of rolls through the rotating shaft 23. The rotation axis is perpendicular to the extending direction of the roll shaft key of the pair of rolls. The swinging jib 2 is arranged to swing around the rotation axis. The swinging jib 2 swings when disassembling the roll skin 3 of the pair of rolls. The second end 22 of the swinging jib 2 drives the connecting component to gradually move away from the roll shaft of the pair of rolls with the rotating shaft 23 as the fulcrum, and finally separates the roll skin 3 of the pair of rolls from the roll shaft key.

[0030] The connecting component serves as the connecting structure and force transmission structure between the swinging jib 2 and the roll skin 3 of the pair of rolls. The connecting component includes a movable connecting member 41. The movable connecting member 41 is installed at the second end 22 of the swinging jib 2 and can adjust its position along the length direction of the swinging jib 2. The movable connecting member 41 extends from the swinging jib 2 towards the roll shaft of the pair of rolls. The movable connecting member 41 is provided with a lifting and pulling member 42 that can be inserted into the hole 31 at the end of the roll skin 3 of the pair of rolls.

[0031] The driving component serves as the power source of the counter-roller shell disassembly device, and is used to drive the swing jib 2 to swing around the rotation axis, and move the second end 22 of the rotation jib away from the counter-roller shaft.

[0032] Combined with Figure 1 , when using the disassembly device in the above technical solution to disassemble the counter-roller shell 3, place the roller shaft support component 1 on the counter-roller shaft, the swing jib 2 straddles the counter-roller shell 3 to be disassembled along the axial direction of the counter-roller shaft, adjust the distance between the connecting component and the counter-roller shell 3 so that the connecting component is close to the end face of the counter-roller shell 3, insert the lifting component 42 into the hole at the end of the counter-roller shell 3, start the driving component, and under the action of the driving component, the counter-roller shell 3 will be slowly lifted away from the counter-roller shaft key, and thus the roller shell 3 can be easily disassembled.

[0033] The present invention effectively overcomes the friction resistance that increases sharply due to the improvement of the assembly accuracy between the counter-roller shell 3 and the counter-roller shaft key, the shear deformation of the shaft key, and the rust adhesion during the use process. By using the hole at the end of the counter-roller shell 3 as the force application point and combining with the driving of the swing jib 2 by the driving component, the roller shell 3 can be stably, reliably and easily disassembled. The device has the characteristics of small size, low cost, stable performance, reliable work and maintenance-free.

[0034] In some embodiments, referring to Figure 1 , in order to ensure the stability of the load support system established by the roller shaft support component 1 and reduce the local pressure on the counter-roller shaft, one end of the roller shaft support component 1 forms a base 11, and the base 11 has an arc surface 12 matching the outer peripheral surface of the counter-roller shaft. The roller shaft support component 1 can be supported on the outer peripheral surface of the counter-roller shaft through the arc surface 12. When disassembling the counter-roller shell 3, the base 11 can be quickly positioned and installed on the outer peripheral surface of the counter-roller shaft through the arc surface 12 of the base 11.

[0035] The components of the roller shell disassembly device can be assembled into a whole, and the integrity of the structure is maintained during the disassembly process of the counter-roller shell 3. The components of the roller shell disassembly device can also be decomposed into multiple independent parts. For example, in some embodiments, referring to Figure 1, a through groove 13 is provided at the other end of the roller support member 1. The through groove 13 extends along the axial direction of the counter-roller shaft and penetrates through the roller support member 1. The through groove 13 sinks from the end surface of the roller support member 1 towards the base 11. Oppositely distributed rotating shaft mounting grooves 14 are provided on both side walls of the through groove 13. The rotating shaft mounting grooves 14 sink from the end surface of the roller support member 1 towards the base 11. The swing jib 2 is detachably mounted in the through groove 13, and the rotating shaft 23 is detachably mounted in the rotating shaft mounting groove 14. When disassembling the roller skin 3, place the roller support member 1 on the counter-roller shaft, insert the rotating shaft 23 into the shaft hole of the swing jib 2, and place the combination of the rotating shaft 23 and the swing jib 2 at the end of the roller support member 1. Among them, the swing jib 2 is embedded in the through groove 13, and the rotating shaft 23 is embedded in the rotating shaft mounting grooves 14 on both side walls of the through groove 13 to form a rotation fulcrum for the swing of the swing jib 2. In this embodiment, an assembly structure in which the swing jib 2 and the roller support member 1 can be quickly disassembled and assembled is formed through the through groove 13 and the rotating shaft mounting grooves 14, which can quickly assemble each group of accessories on site, improve the flexibility of on-site operation, and reduce the impacts such as heavy weight and inconvenience in adjustment caused by assembling each component into a whole.

[0036] In some embodiments, referring to Figure 1 , the movable connection member 41 extends from the first surface to the second surface in the thickness direction. The movable connection member 41 is provided with a guiding through hole 43 that penetrates from the first surface to the second surface. The second end 22 of the swing jib 2 is inserted into the guiding through hole 43. The movable connection member 41 is sleeved on the second end 22 of the swing jib 2. The movable connection member 41 adjusts its position along the length direction of the swing jib 2 through the sliding fit of the guiding through hole 43 and the swing jib 2, so as to adjust the distance between the movable connection member 41 and multiple roller skins 3 to make the movable connection member 41 closely adhere to the multiple roller skins 3.

[0037] It can be understood that the movable connection member 41 can also adopt other structural forms to adjust its position along the length direction of the swing jib 2. For example, it is installed on the second end 22 of the swing jib 2 by setting a guide rail slider or the like, so as to be able to adjust its position along the length direction of the swing jib 2.

[0038] In some embodiments, referring to Figure 1 , the swing jib 2 has a non-circular cross-section, and the guiding through hole 43 is a profiling hole matching the cross-sectional shape of the swing jib 2. On the one hand, the matching relationship of the non-circular cross-section can better realize the force transmission between the swing jib 2 and the movable connection member 41. On the other hand, the matching relationship of the non-circular cross-section can prevent the movable connection member 41 from rotating relative to the swing jib 2, and can better maintain a stable connection with the counter-roller skin 3.

[0039] In some embodiments, referring to Figure 1The movable connection component 41 is provided with a lifting component installation hole 44 that passes from the first surface to the second surface. One or more lifting component installation holes 44 are provided. The lifting component 42 is installed in the lifting component installation hole 44. The lifting component 42 can be extended and retracted along the lifting component installation hole 44 to adjust the length of the lifting component 42 extending in the direction of the hole at the end of the roller skin 3. When disassembling the roller skin 3, adjust the distance between the connecting component and the roller skin 3 so that the connecting component is close to the end surface of the roller skin 3, insert the lifting component 42 into the hole at the end of the roller skin 3, and ensure that the lifting component 42 is inserted into the bottom of the hole in the roller skin 3 to avoid damage due to local force on the hole.

[0040] Furthermore, the lifting and pulling component 42 includes a lifting and pulling pin, which is made of 40cr and subjected to a quenching and tempering heat treatment to ensure its structural strength.

[0041] It is understandable that the lifting and pulling component 42 can also be a boss directly set on the movable connecting component 41, and inserted into the hole at the end of the roller skin 3 by adjusting the position of the movable connecting component 41 along the swing arm 2.

[0042] In some embodiments, the driving component includes a jack, which is used to support between the second end 22 of the connecting assembly and the roller shaft. The jack is arranged on the side of the connecting assembly away from the roller shaft supporting component 1. When removing the roller skin 3 of the roller, the jack is started, and under the action of the lifting force, the distance between the second end 22 of the swing arm 2 and the roller shaft gradually increases, and the multiple roller skins 3 will be slowly lifted and separated from the roller shaft key, so that the roller skin 3 can be easily removed.

[0043] Among them, see Figure 1 The second end 22 of the swing arm 2 is provided with a flat bottom surface cooperating with the jack.

[0044] It is understandable that the driving component can also adopt a manual hoist or an electric hoist, and when in use, it is directly hung on the overhead crane in the workshop.
