Description

Technical Field

[0001] The utility model relates to the technical field of disassembly tools, in particular to a tool for disassembling a special-shaped tube bearing. Background Art

[0002] When routine maintenance personnel replace special-shaped tube bearings, they usually use a special puller tool to first clamp the outside of the special-shaped tube bearing, and then turn the wrench of the puller tool to release the connection between it and the special-shaped tube, thereby completing the disassembly work.

[0003] At present, when using a puller tool to disassemble a special-shaped tube bearing, if the special-shaped tube and the bearing are clamped too tightly, the puller may not be able to fix the special-shaped tube bearing. When the operator pulls the handle, the part where the puller and the special-shaped tube bearing are clamped needs to be pinched from the outside by the operator's other hand, otherwise the part where the puller and the special-shaped tube bearing are clamped is easy to separate from the special-shaped tube bearing. This is not only difficult to operate, but also makes it difficult to disassemble the special-shaped tube bearing. Therefore, a solution is urgently needed.

[0027] Example

[0028] See also Figure 1-5 As shown:

[0029] The utility model provides a tool for disassembling a special-shaped pipe bearing, comprising a connecting block 11, a clamping part, a locking part and a handle 13.

[0030] The clamping part is set as an opening and closing structure that is symmetrical in the vertical direction. The top end of the clamping part is connected to the connecting block 11, and the bottom end is clamped with both sides of the bearing B at the end of the special-shaped tube A; the locking part is sleeved on the outside of the clamping part; one end of the handle 13 is threadedly connected to the connecting block 11, and after passing through the connecting block 11 in the vertical direction, it abuts against the end of the special-shaped tube A.

[0031] The connecting block 11 is a cylinder, and a vertical through hole is provided at the center of the cylinder in the vertical direction, and an internal thread is provided on the inner wall of the through hole. The handle 13 is an L-shaped rod, and an external thread is provided on the short rod of the L-shaped rod, and the short rod is threadedly connected with the vertical through hole.

[0032] With such a configuration, in actual use, when the bearing B at the end of the special-shaped tube A needs to be disassembled, the operator only needs to open the clamping part, clamp the clamping part to the outer side of the bearing B, and then put the locking part on the outside of the clamping part, so that the clamping part and the outer side of the bearing B are more tightly clamped. Then, by rotating the handle 13 so that its end abuts against the end of the special-shaped tube A, and then continuously rotating the handle 13 so that the end of the handle 13 applies a squeezing force to the end of the special-shaped tube A, the clamping part can pull out the bearing B, thereby completing the disassembly work between the special-shaped tube A and the bearing B, which is easy to operate, easy and convenient, and has high disassembly efficiency.

[0033] U-shaped notches are provided on both sides of the connecting block 11 ; the clamping portion is mainly composed of a clamping block 12 and a hinge block 14 .

[0034] In actual use, the clamping block 12 is set as a hollow semi-cylinder or a hollow semi-cylinder, and there are two clamping blocks 12, one on the left and one on the right, which are symmetrically distributed.

[0035] The top of the clamping block 12 is connected to the bottom of the hinge block 14. The top of the hinge block 14 is inserted into the U-shaped notch and is hinged with the connecting block 11 through the pin 15. A groove is provided on the inner wall of the clamping block 12, and the groove is clamped with the side wall of the bearing B.

[0036] Through such an arrangement, the clamping portion forms a clamping claw that can clamp the side wall of the bearing B, thereby facilitating the operator to clamp the side wall of the bearing B.

[0037] The locking part includes a ring 20 and a manual adjustment bolt 21. The ring 20 is sleeved on the outer wall of the clamping block 12 clamped on both sides of the bearing B; there are two manual adjustment bolts 21, which are symmetrically arranged on both sides of the ring 20, and the manual adjustment bolts 21 are threadedly connected with the bolt holes arranged on both sides of the ring 20.

[0038] In actual use, the diameter of the ring 20 is larger than the diameter of the clamping block 12. When it is mounted on the outside of the clamping block 12, the ends of the two manual adjusting bolts 21 are respectively abutted against the outer sides of the two clamping blocks 12 by rotating the manual adjusting bolts 21, thereby making the clamping between the clamping block 12 and the side wall of the bearing B tighter.

[0039] The locking part is provided by two semicircular rings 30 and connecting bolts 32 of the same structure.

[0040] A movable bolt connection block 31 is provided at one end of the semicircular ring 30, and a fixed bolt connection block is provided at the other end. The movable bolt connection block 31 is hinged with the end of the semicircular ring 30 through a hinge shaft 33, and bolt connection holes are provided on the movable bolt connection block 31 and the fixed bolt connection block, and the connection bolts 32 are threadedly connected with the bolt connection holes.

[0041] In actual use, a connecting bolt 32 is first passed through the movable bolt connecting block 31 of the semicircular ring 30 and then connected to the fixed bolt connecting block of the other semicircular ring 30 to form a clamping ring structure, and then the clamping ring structure is clamped on the outer wall of the clamping block 12, and then another connecting bolt 32 is used to respectively connect the movable bolt connecting block 31 and the fixed bolt connecting block on the two semicircular rings 30, so that the clamping ring structure can be tightened on the outer side of the clamping block 12, so that the clamping block 12 and the side wall of the bearing B are clamped more tightly.

[0042] When the diameter of the clamping ring structure enclosed by the two semicircular rings 30 is smaller than the diameter of the clamping block 12, since the movable bolt connecting block 31 is hinged with the end of the semicircular ring 30 through the hinge shaft 33, when the connecting bolt 32 connects the movable bolt connecting block 31 and the fixed bolt connecting block on the two semicircular rings 30, even if the movable bolt connecting block 31 and the fixed bolt connecting block are in a non-parallel state, the operator can adjust the movable bolt connecting block 31 to make it parallel to the fixed bolt connecting block, so that the connecting bolt 32 can smoothly connect the movable bolt connecting block 31 and the fixed bolt connecting block on the two semicircular rings 30.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
