Technical Field

[0001] This utility model relates to the field of mechanical tool technology, and in particular to a device for quickly removing broken wires. Background Technology

[0002] Whether in pipe repair or equipment maintenance, due to prolonged use and material creep, the strength of the threads at the connection decreases, and they may break when force is applied. Part of the thread may break off inside. To remove the broken thread, multiple trades need to work together, and a sufficiently large space is required for the operation. This is even more difficult when replacing bearings in spaces with special requirements. In order to solve the problem of difficult thread removal in actual work, it is necessary to set up a device for quick removal of broken threads. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example

[0019] refer to Figure 1 This embodiment proposes a device for quickly removing broken wires, including a driving component 1. The lower end of the driving component 1 is connected to an expansion part 2. A support part 3 is provided on one side of the expansion part 2. The support part 3 can adjust the expansion degree of the expansion part 2. When removing the broken wire, the part of the expansion part 2 below the support part 3 is inserted into the broken wire. At this time, the support part 3 is located outside the broken wire. The support part 3 is adjusted so that the expansion part 2 expands to make close contact with the inner surface of the broken wire. The upper end of the driving component 1 is rotated, and the driving component 1 drives the broken wire to rotate through the expansion part 2, so that the broken wire can be removed quickly and effortlessly.

[0020] refer to Figure 1 and Figure 2The expansion part 2 includes a first friction plate 201 and a second friction plate 202. One end of the first friction plate 201 and one end of the second friction plate 202 are respectively connected to the lower end of the driving member 1, and the first friction plate 201 and the second friction plate 202 are arranged opposite to each other. The support member 3 passes through the first friction plate 201 and is threadedly connected to the first friction plate 201. The expansion degree of the expansion part 2 can be controlled by rotating the support member 3. Before the expansion part 2 is inserted into the broken wire, the support member 3 is rotated outward to reset the expansion part 2. After the expansion part 2 is inserted into the broken wire, the support member 3 is rotated inward so that one end of the support member 3 located between the first friction plate 201 and the second friction plate 202 abuts against the second friction plate 202. At the same time, force is applied to the second friction plate 202 to open the first friction plate 201 and the second friction plate 202 until the outer surfaces of the first friction plate 201 and the second friction plate 202 are in close contact with the inner surface of the broken wire.

[0021] In this embodiment, the outer surfaces of the first friction plate 201 and the second friction plate 202 are both arc-shaped. Since the broken wire is generally circular, the arc-shaped surface can better fit with the inner surface of the broken wire, ensuring the stability of the broken wire during rotation. In order to increase the friction between the expansion part 2 and the broken wire, the outer surfaces of the first friction plate 201 and the second friction plate 202 of this utility model are provided with threads.

[0022] In this embodiment, the first friction plate 201 and the second friction plate 202 can be integrally connected with the driving component 1, or they can be connected by bolts.

[0023] In the above embodiments, the driving component 1 is preferably a live bolt, which is readily available and easy to process. The expansion part 2 can be obtained by slotting the lower end of the live bolt. The support component 3 is preferably a bolt, which is widely available and does not require processing. It can be directly assembled onto the expansion part 2.

[0024] The specific embodiments of this utility model are provided to enable those skilled in the art to understand or implement this utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.

[0025] It should be understood that this utility model is not limited to the content already described above, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
