[0040] The present application will be described below with reference to the accompanying drawings:

[0041] Figure 1 A schematic diagram of a roller replacement hanger in use in some embodiments or certain embodiments of the present application is shown, with reference to Figure 1 It can be seen that the embodiment of the present application provides a roller replacement hanger, which is used to connect the roller 10, including:

[0042] The U-shaped body 1 is provided with a hanging point 11 .

[0043] The two connecting members 2 are respectively fixed on both sides of the U-shaped body 1 and are spaced apart from the hanging point 11. The side of the two connecting members 2 opposite to each other is a connecting side 21. Each connecting member 2 is provided with at least two spaced cavities 22, and the cavity 22 is adjacent to the corresponding connecting side 21.

[0044] The locking mechanism 3 is embedded in the cavity 22 in a one-to-one correspondence, and is provided with a locking block 31 that is reciprocally telescopic and can extend between the cavity 22 and the connecting side 21 .

[0045] The mounting member 4 corresponds one-to-one to the connecting member 2 , and both sides of the mounting member 4 are respectively provided with locking grooves 41 that match one-to-one with at least two locking blocks 31 , and an insertion groove 42 for sleeve-mounting one end of the roller 10 .

[0046] When it is necessary to replace the roller 10 of the belt or other types, the lifting point 11 of the U-shaped body 1 in the roller replacement sling can be used to connect with the lifting equipment, etc., and two connecting parts 2 are fixedly connected on both sides of the U-shaped body 1, both of which are spaced apart from the lifting point 11. The side of the connecting parts 2 opposite to each other is the connecting side 21, and each connecting part 2 is provided with at least two spaced cavities 22, and the cavity 22 is adjacent to the corresponding connecting side 21. At least two locking mechanisms 3 are arranged in the corresponding cavity 22, and the locking block 31 of the locking mechanism 3 can be reciprocated and extended between the cavity 22 and the connecting side 21, and can extend out of the connecting side 21 of the connecting part 2 to cooperate with the locking groove 41 provided with the corresponding mounting part 4, and inserted into the locking groove 41 to fix the connecting part 2 and the mounting part 4. The two mounting members 4 correspond to the two connecting members 2 one by one, and the two mounting members 4 are connected to the connecting sides 21 of the two connecting members 2 opposite to each other. The other side of each mounting member 4 is used to sleeve one end of the roller 10. The two mounting members 4 can be inserted into the two ends of the same roller 10 through the insertion groove 42, and the other side of each mounting member 4 is sleeved to the locking block 31 one by one through at least two locking grooves 41. The two ends of the roller 10 are fixed between the two mounting members 4. Each mounting member 4 is supported between the two connecting members 2 by the cooperation of multiple locking grooves 41 and the locking block 31. The whole is then lifted by the lifting equipment together with the U-shaped body 1 fixedly connected to the connecting member 2. Both ends of the roller 10 can be fixed, and the mounting member 4 and the connecting member 2 are matched through multiple locking blocks 31 and locking grooves 41, and the positioning effect is good. The old roller 10 can be lifted and transferred by the lifting equipment, and the locking block 31 of the locking mechanism 3 of the connecting member 2 is retracted to lower the old roller 10 and the mounting member 4, and then the two ends of the new roller 10 are respectively inserted into the insertion grooves 42 of the two mounting members 4, and the whole is connected by the locking block 31 and the locking groove 41, and the new roller 10 is lifted, transferred and installed, which reduces the possibility of the roller 10 shaking and falling during the lifting and transfer process, and to a certain extent solves the technical problem of unsatisfactory safety during the replacement of the roller 10.

[0047] In addition, by adopting the above structure, during the transfer and lifting process, the roller 10 is located between the two mounting parts 4, and the U-shaped main body and the two connecting parts 2 can also play a certain protective role for the roller 10, and can also reduce the possibility of collision accidents of the roller 10, which is beneficial to improving the safety of the roller 10 during the lifting and transfer process.

[0048] In some or certain embodiments, the side of the mounting member 4 having the locking groove 41 is the abutting side, which is in close contact with the connecting side 21. This can increase the contact area between the mounting member 4 and the connecting member 2, thereby improving the safety of the roller 10 during lifting and transfer.

[0049] In some or certain embodiments, the mounting member 4 comprises:

[0050] The supporting portion 43 is in the shape of a rectangular parallelepiped and has a locking groove 41 on one side in the width direction.

[0051] The columnar connecting portion 44 is fixedly connected to the supporting portion 43 and axially arranged along the width direction of the supporting portion 43 . An insertion groove 42 is provided at one end thereof away from the locking groove 41 .

[0052] The rectangular support portion 43 of the mounting member 4 can cooperate with the support portion 43 of another mounting member 4 when installing the roller 10 to support the roller 10. The columnar connecting portion 44 is fixedly connected to the support portion 43, providing space for the insertion slot 42 and controlling the structure of the mounting member 4 to be relatively compact. A locking slot 41 is provided on one side of the width direction of the support portion 43. The connecting portion 44 is axially arranged along the width direction of the support portion 43, and an insertion slot 42 is provided on the end away from the locking slot 41, which can reduce the overall width of the roller 10 replacement tool.

[0053] In addition, the mounting member 4 and the roller 10 are matched with an insertion groove 42, and one end of the roller 10 can be extended into the insertion groove 42. This structure also makes the two mounting members 4 applicable to different rollers 10 with a certain fluctuation in roller head size and length range, thereby improving the versatility of the roller 10 replacement tool.

[0054] It should be noted that Figure 1 The middle mounting member 4 is only a feasible structure of the mounting member 4 and is not used to limit the matching mode between the mounting member 4 and the roller 10 .

[0055] In some or certain embodiments, both ends of the connecting portion 44 may be flush with the two side surfaces in the width direction of the supporting portion 43, so as to facilitate the movement of the mounting member 4 and reduce the overall volume.

[0056] Figure 2 Schematic diagram showing the matching state of a roller and a mounting member in some embodiments or certain embodiments of the present application, with reference to Figure 2 It can be seen that in some or certain embodiments, the insertion hole on the mounting member 4 can be a circular groove, and one end of the roller 10 can be inserted into the circular groove.

[0057] In some or certain embodiments, the mounting member 4 can also be configured as a block or prism shape according to needs, and the insertion groove 42 can also be configured as a U-shaped groove according to needs. It can also be used for disassembly, assembly, and replacement of most rollers 10.

[0058] In some or certain embodiments, the inner wall of the U-shaped body 1 forms a U-shaped through groove 12, and the at least two cavities 22 of each connecting member 2 are spaced apart along the extension direction of the U-shaped through groove 12. With this arrangement, when the roller 10 is connected to the connecting block via the mounting member 4, the force direction between the locking block 31 of the locking mechanism 3 and the locking groove 41 of the mounting member 4 in the at least two cavities 22 is likely to have a certain angle with the axial direction of the roller 10, which can play a certain role in tightening and preventing the roller 10 from falling off, and improve the stability of the roller 10 during lifting and transfer.

[0059] Figure 3 A schematic diagram of the structure of a connector in some embodiments or certain embodiments of the present application is shown, combined with Figure 1 and Figure 3 In some or certain embodiments, the connector 2 is rectangular and extends in the longitudinal direction of the U-shaped through-slot 12. Both ends of the connector 2 protrude from the U-shaped body 1, and two cavities 22 are respectively provided at the ends of the corresponding connector 2. This structure can improve the center of gravity stability of the roller replacement spreader during transportation, which is conducive to the stable lifting and replacement of the roller 10.

[0060] In some or certain embodiments, the cavity 22 is a rectangular parallelepiped cavity, and the extension direction of the locking block 31 is arranged along the length direction of the cavity 22. The processing is easier, and the four side walls of the cavity 22 can also play a role in facilitating positioning during installation.

[0061] In some or certain embodiments, the distances between the lifting points 11 of the U-shaped body 1 and the two sides of the U-shaped body 1 can be equal, and the lifting points 11 can be set as lifting ears, etc., which can cooperate with a hook or a lifting rope to achieve stable lifting and transfer of the entire roller replacement spreader.

[0062] In some or certain embodiments, the U-shaped body 1 can be configured as a solid or hollow structure according to requirements. The U-shaped body 1 can also have two or more lifting points 11, etc., to achieve flexible coordination with lifting equipment.

[0063] Figure 4 A schematic structural diagram of a U-shaped body in some embodiments or certain embodiments of the present application is shown. Figure 5 Shows this application Figure 4 The enlarged view of point A in the figure, combined with Figure 4 and Figure 5 In some or certain embodiments, the connector 2 is provided with a strip groove 23 communicating with the cavity 22 and extending in the longitudinal direction along the telescopic direction of the locking block 31. The locking mechanism 3 further includes:

[0064] The guide member 32 is disposed in the cavity 22 and fixedly connected to the locking block 31 . The guide member 32 is movably extended into the strip groove 23 along the length direction of the strip groove 23 .

[0065] The tension spring 33 has two ends connected to the guide member 32 and the cavity wall of the cavity 22 respectively, and its extension direction extends along the extension direction of the locking block 31 .

[0066] The guide member 32 in the locking mechanism 3 is fixedly connected to the locking block 31 and movably extends into the strip groove 23 along the length of the strip groove 23. The length of the strip groove 23 extends along the direction of expansion and contraction of the locking block 31. Therefore, when the locking block 31 is extending or retracting, the guide member 32 can move along the length of the strip groove 23, guiding the locking block 31 and facilitating rapid positioning and engagement between the locking block 31 and the locking groove 41. A tension spring 33, whose ends are respectively connected to the guide member 32 and the wall of the cavity 22 and extends in the direction of expansion and contraction of the locking block 31, can apply a force to the locking block 31 through the guide member 32, thereby maintaining a relatively stable position. When the power for expanding and contracting the locking block 31 is not mechanical, the tension spring 33 can also reset the locking block 31. The overall structure is simple and has a long service life.

[0067] In some or certain embodiments, when the locking block 31 extends beyond the cavity 22 and the connecting side 21 of the connector 2, the tension spring 33 can be in a natural state. The locking block 31 extending beyond the connecting side 21 can directly engage with the locking groove 41, facilitating a long-term engagement and locking of the locking block 31 and the locking groove 41.

[0068] In some or certain embodiments, one end of the guide member 32 that is inserted into the strip groove 23 is a limiting end 321. The cross-section of the strip groove 23 is L-shaped, and the cross-section of the limiting end 321 matches the cross-section of the strip groove 23. The guide member 32 and the strip groove 23 are matched in this manner, which facilitates the insertion of the guide member 32 into the strip groove 23. The matching of the strip groove 23 and the limiting end 321 can also limit the distance between the guide member 32 and the locking block 31, so that the guide member 32 can simultaneously guide and limit the locking block 31, thereby improving the stability of the tool for replacing the roller 10.

[0069] In some or certain embodiments, the connector 2 is provided with a strip-shaped operating hole 24 on a side facing away from the connecting side 21 and connected to the cavity 22. The connector 2 is provided with a through hole 25 for the locking block 31 to pass through. The locking mechanism 3 further includes:

[0070] The movable rod 34 is movably inserted into the operating hole 24 along the length direction of the operating hole 24 , with two ends thereof respectively located inside and outside the cavity 22 . The movable rod 34 is spaced apart from the locking block 31 .

[0071] The movable rod 35 is located in the cavity 22 and has two ends rotatably connected to the locking block 31 and the moving rod 34 . The rotation plane of the movable rod 35 is parallel to the length direction of the operating hole 24 .

[0072] The connector 2 has a strip-shaped operating hole 24 on the side facing away from the connecting side 21, which communicates with the cavity 22. A movable rod 34 is inserted into the operating hole 24, with its ends positioned inside and outside the cavity 22, respectively. The end of the movable rod 34 outside the cavity 22 provides operating space, allowing the movable rod 34 to move along the length of the operating hole 24. The movable rod 34 is spaced apart from the locking block 31 and connected thereto by a movable rod 35. The rotation plane of the movable rod 35 is parallel to the length of the operating hole 24. Pushing one end of the movable rod 34 along the length of the operating hole 24 changes the distance between the movable rod 34 and the locking block 31. The movement of the movable rod 34 is transmitted to one end of the movable rod 35, causing the movable rod 35 and the locking block 31, to which the other end of the movable rod 35 is rotatably connected, to move. The locking block 31 is constrained by the through-hole 25 to allow only telescopic movement. Therefore, the movement of the movable rod 34 along the length of the operating hole 24 is ultimately converted into rotation of the movable rod 35 along the rotation plane and telescopic movement of the locking block 31. The structure is simple and compact, and easy to operate. The resetting of the locking block 31 and the moving rod 34 can be adjusted by the tension spring 33 and manpower.

[0073] In some or certain embodiments, the movable rod 34 and the movable rod 35 may be replaced by a movable plate and an movable plate of a certain length, respectively, to achieve corresponding movements.

[0074] In some or certain embodiments, the locking mechanism 3 further comprises:

[0075] The guide rod 36 is fixedly connected to the cavity 22 and movably passes through the movable rod 34 . The length direction of the guide rod 36 extends along the length direction of the operating hole 24 .

[0076] The guide rod 36 can limit the movable rod 34 and facilitate pushing the movable rod 34 .

[0077] In some or certain embodiments, the locking mechanism 3 further comprises:

[0078] The return spring 37 is connected to the cavity wall of the cavity 22 and the moving rod 34 at both ends, and the return spring 37 is extended and retracted along the length direction of the operating hole 24. The return spring 37 cooperates with the tension spring 33 to achieve rapid positioning of the locking block 31 and the moving rod 34.

[0079] In some or certain embodiments, the cavity 22 of the connector 2 may be rectangular, the through hole 25 and the operating hole 24 may communicate with two opposite walls of the cavity 22, the strip hole may be provided on the side wall of the cavity 22 between the operating hole 24 and the through hole 25, and the tension spring 33 and the return spring 37 may be connected and provided accordingly based on the space available. This improves space utilization and helps reduce the space and weight required by the connector 2.

[0080] In some or certain embodiments, the U-shaped body 1, connector 2, mounting member 4, and the locking block 31, guide member 32, guide rod 36, movable rod 35, and movable rod 34 of the locking mechanism 3 can all be made of corresponding aluminum alloy materials. This lightweight structure reduces the burden on the lifting equipment, which can be an overhead crane or a crane as needed.

[0081] In some or certain embodiments, the locking mechanism 3 may include a driving member such as a motor or a telescopic cylinder disposed within the cavity 22. The locking block 31 may be fixedly connected to the output shaft of the motor or the telescopic rod of the telescopic cylinder. The motor and telescopic cylinder may be extended or retracted to allow the locking block 31 to be inserted into the locking groove 41 for engagement, or the locking block 31 may be withdrawn from the locking groove 41, allowing the mounting member 4 to be separated from the connecting member 2. When the locking mechanism 3 includes a motor and a telescopic cylinder to provide the locking block 31 with telescopic power, a guide structure, such as a guide rail or the guide member 32 described above, may also be disposed within the cavity 22 for guiding the locking block 31.

The descriptions mentioned in this application are all one of the states after the roller replacement tool is assembled, and are not intended to limit the roller replacement tool to the state of being incomplete.
