Description

Technical Field

[0001] The utility model relates to the field of extractors, in particular to a mechanical tension type broken wire extractor. Background Art

[0002] Traditional broken wire extractors are usually manually operated tools. Manual broken wire extractors require users to apply greater force and precise operation to extract the broken bolts, which is not only laborious in operation but also prone to fatigue for long-term work, so there is room for improvement. Content of the Utility Model

[0003] The purpose of the utility model is to provide a mechanical tension type broken wire extractor to solve the problems put forward in the above background art, which has the advantage of conveniently extracting the water pipe and the broken head of the joint from the pipeline.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A mechanical tension type broken wire extractor, including a housing, a through groove penetrating the housing is arranged in the middle of the housing, corresponding pressing plates are arranged in the through groove, an extruding member for driving the pressing plates to move outwards is arranged between the two pressing plates, and limiting plates that are always inside the housing are integrally connected to both ends of the pressing plates.

[0005] By adopting the above technical solution, place the housing on the pipeline to be extracted, then start the extruding member to make the two pressing plates move away from each other until the two pressing plates press against the inner wall of the pipeline broken wire. When the extruding member stops moving, the extruding member will be stuck with the pressing plates and the housing to form a whole, and then rotate the extruding member to drive the pressing plates to rotate and then drive the pipeline broken wire fixed by the pressing plates to rotate. The rotation direction is the reverse thread direction, so as to drive the pipeline broken wire to rotate out in the reverse thread direction, thereby extracting the pipeline broken wire.

[0006] As a further scheme of the utility model: The extruding member includes a cone between the pressing plates. One end of the cone is integrally connected with a threaded block, the threaded block is in threaded engagement with the inner part of the housing, and a connecting shaft is integrally connected to the middle of the threaded block.

[0007] By adopting the above technical solution, connect an external electric gun to the connecting shaft, so as to drive the connecting shaft to rotate by the electric gun and then drive the threaded block to rotate. The rotation of the threaded block can make it move inside the housing and then drive the cone to move. The movement of the cone can squeeze the pressing plates on both sides to move away from each other, so that the pressing plates are pressed and fixed with the inner wall of the pipeline broken wire.

[0008] As a further scheme of the utility model: The thread on the outer side of the threaded block is set as a reverse thread.

[0009] By adopting the above technical solution, in this process, the threads of the thread block and the shell are set as reverse threads, so that the pipeline can be rotated in the reverse thread when the broken wire of the pipeline is driven to rotate, thereby facilitating the removal of the broken wire of the pipeline.

[0010] As a further solution of the utility model: the side of the extrusion plates facing each other is arranged as an inclined surface.

[0011] By adopting the above technical solution, the setting of the inclined surface allows the extrusion plate to fit more closely with the cone.

[0012] As a further solution of the utility model: the side surface of the shell is threadedly connected to a limiting block.

[0013] By adopting the above technical solution, when not in use, the threaded block in the shell is easy to fall out of the shell, and a part of the limiting block can be placed in the shell to limit the separation of the threaded block from the shell.

[0014] As a further solution of the utility model: a circular hole penetrating the shell is arranged at one end of the shell.

[0015] By adopting the above technical solution, the setting of the circular hole allows a part of one end of the cone to extend out of the shell, thereby increasing the moving distance of the cone.

[0016] As a further solution of the present invention: the side surface of the shell is set to be a plane.

[0017] By adopting the above technical solution, the flat setting can use a wrench to rotate the shell when the external electric gun is inconvenient to rotate.

[0018] As a further solution of the utility model: the sides of the extrusion plates facing away from each other are arranged in a step shape.

[0019] By adopting the above technical solution, the stepped arrangement enables the extrusion plate to be suitable for pipe wire breakage with different apertures.

[0020] As a further solution of the utility model: a multi-stage frustum is arranged on the upper part of the shell.

[0021] By adopting the above technical solution, the arrangement of multi-stage truncated cones can adapt to wire breakage in pipelines with different apertures.

[0022] As a further solution of the utility model: the through groove penetrates multiple frustums at the same time.

[0023] As a further solution of the utility model: a through hole is provided on the side of the shell.

[0024] By adopting the above technical solution, the external rod-shaped object can be inserted into the through hole, thereby facilitating the rotation of the outer shell.

[0025] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0026] Place the frustum part of the outer shell into the pipeline where the broken wire is to be taken out. Then start the extrusion part to move the extrusion plates away from each other until the extrusion plates extrude the inner wall of the broken wire in the pipeline. When the extrusion part stops moving, the extrusion part will be stuck with the extrusion plates and the outer shell to form an integral body. Then rotate the extrusion part to drive the extrusion plates to rotate, and further drive the broken wire in the pipeline fixed by the extrusion plates to rotate. The rotation direction is the reverse thread direction, so as to drive the broken wire in the pipeline to rotate out in the reverse thread direction and be taken out from the pipeline. The extrusion plates are designed to be applicable to pipeline breakheads of different calibers; the force is evenly distributed when contacting with the extrusion part and the pipeline breakhead.
