[0040] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0041] like Figure 1 As shown, according to an embodiment of the present disclosure, a locking sleeve disassembly device is proposed, including: a bracket assembly 100, which is used to be detachably arranged on the locking outer sleeve 900, and the bracket assembly 100 is provided with a sliding hole; a pull rod 200, which is passed through the sliding hole and slidably cooperates with the sliding hole, and the pull rod 200 has a first rod end and a second rod end, and the first rod end is used to be connected to the locking inner sleeve 800, and the sliding hole is located between the first rod end and the second rod end; an adjustment assembly 300, which is transmission-connected to the pull rod 200, and the adjustment assembly 300 is used to drive the pull rod 200 to slide along the conducting direction of the sliding hole.

[0042] The locking sleeve disassembly device proposed in the embodiment of the present disclosure includes a bracket assembly 100, a pull rod 200 and an adjustment assembly 300, wherein a sliding hole is opened on the bracket assembly 100, and the pull rod 200 is inserted into the sliding hole so that the sliding hole is located between the first rod end and the second rod end of the pull rod 200. The pull rod 200 and the sliding hole are in sliding fit, and the pull rod 200 can slide relative to the sliding hole to increase or decrease the distance between the first rod end and the sliding hole. The adjustment assembly 300 is connected to the pull rod 200 in a transmission manner. The component 300 can drive the pull rod 200 to slide in the sliding hole. In actual application, the bracket component 100 is set on the locking outer sleeve 900, and the first rod end of the pull rod 200 is connected to the locking inner sleeve 800, so that the pull rod 200 is adjusted to slide along the sliding hole by adjusting the component 300, so that the first rod end of the pull rod 200 is close to the sliding hole. The pull rod can drive the locking inner sleeve 800 to move along the extension direction of the sliding hole, so that the locking inner sleeve 800 moves to a position extending from the locking outer sleeve 900, thereby realizing the disassembly of the locking inner sleeve 800.

[0043] It can be understood that when the bracket assembly 100 is set on the locking sleeve 900, the conducting direction of the sliding hole can be the same as the axial direction of the axial hole on the locking sleeve 900 for installing the locking inner sleeve 800, so that as the pull rod 200 slides, the locking inner sleeve 800 can be extended along the axial hole of the locking sleeve 900, thereby realizing the disassembly of the locking inner sleeve 800.

[0044] It should be noted that the locking inner sleeve 800 is arranged in the axial hole of the locking outer sleeve 900, and the fitting clearance between the locking inner sleeve 800 and the locking outer sleeve 900 is small. When foreign matter such as steel chips enters the gap between the locking inner sleeve 800 and the locking outer sleeve 900, it is very easy to cause the locking inner sleeve 800 to get stuck relative to the locking outer sleeve 900, causing the rolling mill coiler to stop and the production to be forced to stop. When in use, the locking inner sleeve 800 is located in the axial hole of the locking outer sleeve 900 and moves along the axial direction of the locking outer sleeve 900. Therefore, when the locking inner sleeve 800 gets stuck, foreign matter such as steel chips will often cause the outer surface of the locking inner sleeve 800 to get stuck. The locking inner sleeve 800 is scratched and needs to be disassembled for processing and repair. The traditional method of removing the locking inner sleeve 800 is to move the locking inner sleeve 800 by hammering. However, it is difficult to control the direction of the force applied to the locking inner sleeve 800 by hammering, which can easily cause the locking inner sleeve 800 to be eccentric. It is necessary to frequently adjust the position of the locking inner sleeve 800 by crowbar until the locking inner sleeve 800 is separated from the locking outer sleeve 900. This method has high labor intensity for the staff and extremely low disassembly efficiency. It is also easy to aggravate the scratches on the surface of the locking inner sleeve 800, causing the locking inner sleeve 800 and the locking outer sleeve 900 to be unusable for a long time, seriously affecting the production cycle. Compared with the traditional technology, the locking sleeve disassembly device proposed in the embodiment of the present disclosure is based on the above-mentioned setting. The direction of force applied by the locking sleeve disassembly device to the locking inner sleeve 800 is always along the axial direction of the locking outer sleeve 900, so that the locking inner sleeve 800 can be removed along the hole axis of the locking outer sleeve 900. During the disassembly process, the probability of eccentric jamming of the locking inner sleeve 800 can be reduced, which is more conducive to quickly removing the locking inner sleeve 800, which is conducive to reducing the labor cost of the staff, and is conducive to improving the disassembly efficiency of the locking inner sleeve 800, reducing the time cost of disassembling the locking inner sleeve 800, and at the same time reducing the secondary damage to the locking inner sleeve 800 caused by steel chips, etc., which is conducive to reducing the impact of the jamming of the rolling mill coiler on the production cycle.

[0045] It is understandable that the rolling mill coiler also needs regular maintenance. During the maintenance process, the locking sleeve disassembly device can also be used to disassemble the locking inner sleeve 800, which is beneficial to improving the maintenance efficiency of the rolling mill coiler.

[0046] In some examples, such as Figure 1 As shown, it also includes: a connecting flange 400, connected to the first rod end, the connecting flange 400 is provided with a first through hole, the first through hole is used to correspond to the mounting hole arrangement of the locking inner sleeve 800; a first connecting bolt, used to be detachably passed through the first through hole and the mounting hole of the locking outer sleeve 900.

[0047] In the above technical solution, the locking sleeve disassembly device also includes a connecting flange 400 and a first connecting screw. One side of the connecting flange 400 is connected to the first rod end, and the other side of the connecting flange 400 is used to abut the locking inner sleeve 800. In actual application, the first through hole on the connecting flange 400 corresponds to the mounting hole arrangement of the locking inner sleeve 800, and the first connecting bolt is passed through the first through hole and the mounting hole of the locking outer sleeve 900 to connect the connecting flange 400 to the locking inner sleeve 800, which is conducive to improving the convenience of operation.

[0048] It can be understood that by connecting the pull rod 200 and the locking inner sleeve 800 through the connecting flange 400, the mounting holes on the locking inner sleeve 800 can be directly utilized without the need for additional holes, thereby achieving the connection between the locking inner sleeve 800 and the connecting flange 400, which is conducive to reducing the workload and at the same time can reduce the damage to the locking inner sleeve 800, which is conducive to ensuring the structural strength of the locking inner sleeve 800 and also can ensure the connection strength between the locking inner sleeve 800 and the connecting flange 400.

[0049] It can be understood that the contact surfaces of the locking inner sleeve 800 and the connecting flange 400 can be completely matched. In the case that the locking inner sleeve 800 is stuck, if the axial direction of the locking inner sleeve 800 deviates from the axial direction of the locking outer sleeve 900, the locking inner sleeve 800 and the connecting flange 400 are connected by the first connecting bolt. As the clamping force provided by the first connecting bolt gradually increases, the position of the locking inner sleeve 800 can also be corrected, so that the axial direction of the locking inner sleeve 800 is the same as the axial direction of the locking outer sleeve 900, which is more conducive to the removal of the locking inner sleeve 800.

[0050] In some examples, such as Figure 1 As shown, the adjustment assembly 300 includes: a first adjustment nut 310, the pull rod 200 is formed with an external thread, and the first adjustment nut 310 is threadedly connected to the pull rod 200; wherein, the first adjustment nut 310 is located between the sliding hole and the second rod end.

[0051] In the above technical solution, the adjustment component 300 includes a first adjustment nut 310, which is sleeved on the external thread of the pull rod 200. The first adjustment nut 310 is threadedly connected to the pull rod 200. At the same time, the first adjustment nut 310 is located between the sliding hole and the second rod end. The first adjustment nut 310 can be adjusted to move toward the first rod end. The first adjustment nut 310 will abut the bracket component 100. In this case, the first adjustment lock nut continues to be rotated. Since the first adjustment nut 310 cannot continue to move along the extension direction of the pull rod 200, the pull rod 200 is pulled. The rod 200 will move along the conducting direction of the sliding hole as the first adjusting nut 310 rotates, that is, the first rod end moves in the direction close to the first adjusting nut 310, and then the pull rod 200 will drive the locking inner sleeve 800 to move in the direction of extending out of the locking outer sleeve 900; the first adjusting nut 310 and the pull rod 200 are used in a threaded transmission mode, which has a simple structure, small space occupation, low cost, and is also more convenient for staff to operate. At the same time, the transmission is stable and has a strong axial bearing capacity, which is conducive to the removal of the large-volume and large-mass locking inner sleeve 800.

[0052] In some examples, such as Figure 1 As shown, the adjustment assembly 300 further includes: a second adjustment nut 320 , which is threadedly connected to the pull rod 200 ; wherein the second adjustment nut 320 is located between the sliding hole and the first rod end.

[0053] In the above technical solution, the adjustment component 300 also includes a second adjustment nut 320, which is also threadedly connected to the pull rod 200. The second adjustment nut 320 is located between the sliding hole and the first rod end, that is, the first adjusting nut 310 and the second adjusting nut 320 are respectively located on both sides of the sliding hole. The second adjusting nut 320 can be adjusted to move in a direction closer to and away from the first rod end, and the second adjusting nut 320 will abut the bracket component 100. In this case, the second adjusting nut 320 continues to be rotated, because the second adjusting nut 320 cannot continue to extend along the pull rod 200. The second adjusting nut 320 and the pull rod 200 are used to rotate in the direction of the guide hole, so that the pull rod 200 will move along the conducting direction of the sliding hole as the second adjusting nut 320 rotates, that is, the first rod end moves in the direction away from the second adjusting nut 320, and then the pull rod 200 will drive the locking inner sleeve 800 to move in the direction of extending into the locking outer sleeve 900; the second adjusting nut 320 and the pull rod 200 are used in a threaded transmission mode, which has a simple structure, small space occupation and low cost, and is also more convenient for staff to operate. At the same time, the transmission is stable and has a strong axial bearing capacity, which is conducive to the removal of the large-volume and large-mass locking inner sleeve 800.

[0054] It can be understood that the first adjusting nut 310 and the second adjusting nut 320 are respectively used to adjust the locking inner sleeve 800 to move in the direction of extending out and extending into the locking outer sleeve 900. In actual application, the cooperation of the first adjusting nut 310 and the second adjusting nut 320 makes it easier to remove the locking inner sleeve 800.

[0055] In some examples, such as Figure 1 As shown, the bracket assembly 100 includes: a load-bearing beam 110, one end of which is used to be detachably connected to the locking sleeve 900; a mounting column 120, the number of which is two, and the other ends of the two load-bearing beams 110 are both connected to the mounting column 120, and a sliding hole is opened in the mounting column 120, and the sliding hole is located between the two load-bearing beams 110.

[0056] In the above technical solution, the bracket assembly 100 includes a load-bearing beam 110 and a mounting column 120, wherein a sliding hole is opened on the mounting column 120, one end of the load-bearing beam 110 is set on the mounting column 120, and the number of the load-bearing beams 110 is two, and the sliding hole is located between the two load-bearing beams 110. In actual application, the other end of the load-bearing beam 110 is used to connect the locking sleeve 900, so that the locking sleeve 900, the load-bearing beam 110 and the mounting column 120 can form a frame structure, which is conducive to ensuring structural strength. By setting two load-bearing beams 110 on both sides of the sliding hole, when the adjustment assembly 300 adjusts the pull rod 200 to slide, the two load-bearing beams 110 can provide stable bearing force for the mounting column 120, which is conducive to avoiding changes in the position of the mounting column 120, so as to ensure that the conduction direction of the sliding hole is a direction that is conducive to the disassembly of the locking inner sleeve 800.

[0057] It can be understood that the locking sleeve 900 has two mounting holes, which are located at diagonal positions of the locking sleeve 900. The load-bearing beam 110 can be detachably connected to the mounting holes of the locking sleeve 900, so that the mounting column 120 can pass through the axis of the locking sleeve 900, so that the sliding hole can be opened on the axis of the locking sleeve 900, which makes it easier for the locking inner sleeve 800 to slide relative to the locking sleeve 900 under the drive of the pull rod 200.

[0058] In some examples, such as Figure 1 As shown, the bracket assembly 100 also includes: a connecting plate 130, each load-bearing beam 110 is provided with a connecting plate 130 at one end away from the mounting column 120, and a second through hole is opened on the connecting plate 130, and the second through hole is used to correspond to the mounting hole arrangement of the locking sleeve 900; a second connecting bolt is used to be detachably passed through the second through hole and the mounting hole of the locking sleeve 900.

[0059] In the above technical solution, the bracket assembly 100 also includes a connecting plate 130 and a second connecting bolt. Each load-bearing beam 110 is provided with a connecting plate 130. The connecting plate 130 is located at one end of the load-bearing beam 110 away from the connecting plate 130. A second through hole is provided on the connecting plate 130. In actual application, the second through hole corresponds to the mounting hole arrangement of the locking sleeve 900. The second connecting bolt is passed through the second through hole and the mounting hole of the locking sleeve 900, so that the second connecting bolt connects the locking sleeve 900 and the connecting plate 130, which is conducive to improving the convenience of operation.

[0060] It can be understood that the load-bearing beam 110 and the locking sleeve 900 are connected through the connecting plate 130, and the mounting holes on the locking sleeve 900 can be directly utilized without the need for additional holes, so that the connection between the locking sleeve 900 and the connecting plate 130 can be achieved, which is conducive to reducing the workload and at the same time can reduce the damage to the locking sleeve 900, which is conducive to ensuring the structural strength of the locking sleeve 900 and the connection strength between the locking sleeve 900 and the connecting plate 130.

[0061] In some examples, the support assembly 100 further includes a protective member disposed on the load-bearing beam 110 , wherein the protective member is made of a flexible material.

[0062] In the above technical solution, the bracket assembly 100 includes a protective member, which is arranged on the load-bearing beam 110. The protective member can be made of flexible material. The arrangement of the protective member can, on the one hand, reduce the damage to the staff when the staff collides with the load-bearing beam 110. On the other hand, when the locking inner sleeve 800 is extended from the locking outer sleeve 900, improper operation may cause the locking inner sleeve 800 to completely extend from the locking outer sleeve 900 and fall under the action of gravity. The protective member can reduce the damage when the locking inner sleeve 800 collides with the load-bearing beam 110.

[0063] In some examples, a groove is formed in the pull rod 200 along the axial direction of the pull rod 200 , a protrusion structure is provided in the sliding hole, and the protrusion structure is slidably disposed in the groove.

[0064] In the above technical solution, the pull rod 200 is provided with a groove along the axial direction, and a protrusion structure is provided inside the sliding hole. The protrusion structure and the groove are slidably matched, so that when the adjustment component 300 adjusts the pull rod 200 to slide, the pull rod 200 can be prevented from rotating.

[0065] It can be understood that the locking inner sleeve 800 and the locking outer sleeve 900 are connected by a connecting key to prevent the locking inner sleeve 800 from rotating in the locking outer sleeve 900. If the pull rod 200 rotates, the connecting key is easily damaged. The setting of the protruding structure and the groove can prevent the connecting key from being damaged during the disassembly process of the locking inner sleeve 800.

[0066] In some examples, the invention further includes a handle, which is disposed at the second rod end of the pull rod 200 .

[0067] In the above technical solution, a handle is provided at the second rod end of the pull rod 200, and a pulling force can be applied by the handle to assist the adjustment component 300 to adjust the pull rod 200, which is more conducive to improving the convenience of adjusting the pull rod 200 and making it easier to disassemble the locking inner sleeve 800.

[0068] In some examples, it further includes: a hanging component, which is disposed on the bracket assembly 100 .

[0069] In the above technical solution, a lifting part is also provided on the bracket assembly 100, which can be used to connect to a lifting device so as to facilitate the movement of the locking sleeve removal device through the lifting device. In actual application, the locking sleeve removal device can be moved to a position close to the locking sleeve 900 by the lifting device, thereby making it easier to install the bracket assembly 100 on the locking sleeve 900.
