[0031] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0033] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0034] Please see Figures 1 to 9This utility model provides a pipe joint broken wire and sleeve removal device, including a first opening and closing part 3 and a second opening and closing part 2. The second opening and closing part 2 is arranged corresponding to the first opening and closing part 3. An adjustment component is provided between the first opening and closing part 3 and the second opening and closing part 2. The adjustment component is used to adjust the opening and closing distance between the first opening and closing part 3 and the second opening and closing part 2 so that the first opening and closing part 3 and the second opening and closing part 2 cooperate to tighten the inner wall of the pipe joint broken wire or sleeve 8. When the opening and closing distance between the first opening and closing part 3 and the second opening and closing part 2 is zero, the first opening and closing part 3 and the second opening and closing part 2 are combined into a cylinder. The first opening and closing part 3 and the second opening and closing part 2 are both semi-cylindrical. The cylinder has an acting end for clamping the inner wall of the pipe joint broken wire or sleeve 8 and a force-applying end away from the acting end. The acting end of the cylinder has a first acting segment and a second acting segment arranged sequentially along the direction from the force-applying end to the acting end. The radius of the second acting segment is larger than the radius of the first acting segment. By setting a first action section and a second action section on the cylindrical first opening and closing part 3 and the second opening and closing part 2, and the radius of the second action section is larger than the radius of the first action section, it can adapt to different types of pipe joint broken wires or sleeves 8. At the same time, by adjusting the opening and closing distance between the first opening and closing part 3 and the second opening and closing part 2 with the adjustment component, it can adapt to pipe joint broken wires or sleeves 8 with different inner diameters. This improves the adaptability of the pipe joint broken wire and sleeve 8 extractor to different pipe joint broken wires or sleeves 8, and has good practicality and is easy to use.

[0035] The cylindrical working end also has a limiting protrusion 7 that protrudes radially along the cylinder, and the limiting protrusion 7 is located between the first working section and the second working section. By setting the limiting protrusion 7, the sleeve 8 can be supported at the bottom edge of the sleeve 8 when the pipe joint broken wire and sleeve 8 extractor removes the sleeve 8, thereby enhancing the pulling force when the pipe joint broken wire and sleeve 8 extractor pulls the sleeve 8 upward. At the same time, the limiting protrusion 7 increases the mechanical strength of the pipe joint broken wire and sleeve 8 extractor and improves the stability of the pipe joint broken wire and sleeve 8 extractor during use.

[0036] The pipe joint broken wire and sleeve remover also includes a grip handle 1, which is fixedly connected to the first opening and closing member 3. The grip handle 1 facilitates gripping by the operator. In this embodiment, the grip handle 1 is rod-shaped, with its axis perpendicular to the axis of the cylinder. The grip handle 1 is located at the force-applying end of the cylinder, and the force-applying end is positioned at the midpoint of the grip handle 1. Thus, when removing the sleeve 8, a jack is provided at each end of the grip handle 1 to assist in the removal of the sleeve 8. In this embodiment, the grip handle 1 and the first opening and closing member 3 are integrally formed, thereby increasing their stress-bearing capacity. In some embodiments, the grip handle 1 and the first opening and closing member 3 are connected by welding. The fixed connection method between the grip handle 1 and the first opening and closing member 3 can be adjusted according to actual usage needs.

[0037] Specifically, the handle 1 is fixedly connected to the first opening and closing part 3, and the handle 1 is detachably connected to the second opening and closing part 2 through an adjustable connection structure. This ensures that the force on the first opening and closing part 3 and the second opening and closing part 2 near the handle 1 is balanced during the removal of the broken pipe joint and the sleeve 8. This avoids the first opening and closing part 3 or the second opening and closing part 2 being subjected to force alone near the handle 1, which could lead to the first opening and closing part 3 or the second opening and closing part 2 breaking and affecting the stability of the pipe joint broken pipe joint and sleeve 8 remover during use.

[0038] In detail, the adjusting connection structure includes a fastener and an adjusting slot 9 formed on the grip handle 1. The adjusting slot 9 extends along a first direction, which is the same as the opening and closing direction between the first opening / closing member 3 and the second opening / closing member 2. The above structure is simple and easy to operate. In this embodiment, the fastener is a fixing bolt 4, which passes through the adjusting slot 9 and is threadedly connected to the first opening / closing member 3 or the second opening / closing member 2. The grip handle 1 is also provided with a guide groove for guiding the movement direction of the second opening / closing member 2. At least one end of the second opening / closing member 2 is at least partially accommodated in the guide groove. By providing the guide groove, when the opening and closing distance between the first opening / closing member 3 and the second opening / closing member 2 is adjusted by the adjusting component, the guide groove can guide the movement trajectory of the second opening / closing member 2, thereby improving the stability of the pipe joint wire breakage and sleeve extractor during use.

[0039] The adjustment assembly includes a positioning bolt 6 and an adjusting bolt 5. The first opening and closing member 3 has a first through hole and a first threaded hole, and the second opening and closing member 2 has a second threaded hole, which corresponds to the first through hole. The positioning bolt 6 passes through the first through hole and is threadedly connected to the second opening and closing member 2 through the second threaded hole. The adjusting bolt 5 is threadedly connected to the first opening and closing member 3 through the first threaded hole. The threaded end of the adjusting bolt 5 abuts against the second opening and closing member 2 and cooperates with the positioning bolt 6 to adjust the distance between the first opening and closing member 3 and the second opening and closing member 2. The positioning bolt 6 can position the relative position of the first opening and closing part 3 and the second opening and closing part 2 along the cylindrical axis, and can limit the maximum opening and closing distance between the first opening and closing part 3 and the second opening and closing part 2. When the first opening and closing part 3 and the second opening and closing part 2 enter the inner hole of the pipe joint broken wire or sleeve 8, the opening and closing distance between the first opening and closing part 3 and the second opening and closing part 2 can be increased by adjusting the bolt 5 until the first opening and closing part 3 and the second opening and closing part 2 tighten the inner hole of the pipe joint broken wire or sleeve 8, thereby completing the disassembly of the pipe joint broken wire or sleeve 8.

[0040] In this embodiment, the adjustment assembly includes a positioning bolt 6 and two adjusting bolts 5. The positioning bolt 6 and the two adjusting bolts 5 are arranged at intervals along the axial direction of the cylinder, and the positioning bolt 6 is located between the two adjusting bolts 5. This makes it easy to adjust the opening and closing distance between the first opening and closing member 3 and the second opening and closing member 2 by adjusting the adjusting bolts 5.

[0041] In this embodiment, a positioning blind hole is provided on the second opening and closing member 2, which corresponds to the first threaded hole. The threaded end of the adjusting bolt 5 is at least partially accommodated in the positioning blind hole. The positioning blind hole is used to limit the position of the bolt end of the adjusting bolt 5 on the second opening and closing member 2, so as to prevent the position of the bolt end of the adjusting bolt 5 on the second opening and closing member 2 from changing during the tightening of the adjusting bolt 5, which would affect the thread alignment between the adjusting bolt 5 and the first threaded hole, and thus cause jamming when tightening the adjusting bolt 5.

[0042] In this embodiment, multiple anti-slip grooves extending axially along a cylindrical shape are provided on the outer wall of the first working section, and these grooves are spaced apart circumferentially along the first working section. Since the broken pipe joint wire needs to be rotated before removal during disassembly, the axially extending anti-slip grooves increase the friction between the grooves and the inner hole of the broken pipe joint wire, preventing slippage during rotation.

[0043] In this embodiment, multiple second anti-slip annular grooves extending circumferentially along the cylinder are provided on the outer wall of the first working section. These multiple second anti-slip annular grooves are arranged sequentially at intervals along the circumferential direction of the cylinder. The second anti-slip annular grooves can increase the friction between the broken pipe joint wire and the sleeve extractor and the inner cylinder of the sleeve, making it easier to remove the sleeve 8 from inside the equipment.

[0044] When using a pipe fitting breakage extractor and sleeve extractor to remove a broken pipe fitting thread from a pipe or equipment, first loosen the adjusting bolt 5 and the positioning bolt 6, then tighten the fixing bolt 4. Next, insert the functional ends of the first opening / closing member 3 and the second opening / closing member 2 into the broken thread hole of the pipe fitting. Then loosen the fixing bolt 4 and tighten the adjusting bolt 5. At this time, the functional ends of the first opening / closing member 3 and the second opening / closing member 2 will open and close until they tighten the broken pipe fitting thread. Then tighten the fixing bolt 6. After completing the above actions, the operator can disassemble the pipe fitting by firmly gripping the handle 1 and twisting the broken pipe fitting thread in the opposite direction.

[0045] When using a pipe fitting broken thread and sleeve extractor to remove and disassemble the sleeve 8 embedded in equipment or pipe, the steps are basically the same as those for removing a pipe fitting broken thread. First, loosen the adjusting bolt 5 and the positioning bolt 6, then tighten the fixing bolt 4. Next, insert the functional ends of the first opening / closing member 3 and the second opening / closing member 2 into the sleeve 8 to be disassembled, with the limiting protrusion 7 abutting against the lower edge of the sleeve 8. Then, loosen the fixing bolt 4 and tighten the adjusting bolt 5 to open and close the functional ends of the first opening / closing member 3 and the second opening / closing member 2 until they tighten the inner wall of the sleeve 8. Finally, tighten the fixing bolt 6. After completing the above steps, the operator can hold the handle 1 and pull upwards to disassemble the sleeve 8. If the resistance to pulling the sleeve 8 is too great, two jacks can be used, one at each end of the handle 1, to slowly lift the first opening / closing member 3 and the second opening / closing member 2 to pull the sleeve 8 out.

[0046] In summary, by setting a first action section and a second action section on the cylindrical first opening and closing part 3 and the second opening and closing part 2, and with the radius of the second action section being larger than the radius of the first action section, it can accommodate broken pipe fittings or sleeves 8 of different models. At the same time, by adjusting the opening and closing distance between the first opening and closing part 3 and the second opening and closing part 2 with the adjustment component, it can accommodate broken pipe fittings or sleeves 8 of different inner diameters. This improves the adaptability of the pipe fitting broken thread and sleeve extractor to different pipe fitting broken threads or sleeves, and has good practicality and is easy to use.

[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
