Wire body connecting structure of threading machine

Abstract

The utility model belongs to the field of wire body connecting structures of steel belt threading machines, and particularly relates to a wire body connecting structure of a threading machine. A wire body in the threading machine is divided into two sections, namely a first wire body and a second wire body, and the first wire body is detachably connected with the second wire body. The first wire body or the second wire body located in the threading machine is short, if the first wire body is located in the threading machine, one end of the first wire body is fixedly connected with the wire coil, and the other end of the first wire body is connected with one end of the second wire body; and if the second wire body is arranged in the threading machine, one end of the second wire body is fixedly connected with the wire coil, and the other end is connected with one end of the first wire body. When the wire is replaced, the wire coil only needs to send the wire outwards until the joint of the first wire body and the second wire body is exposed outside, and then the wire body can be replaced. After replacement, the wire coil takes up the wire by means of external force, and the replaced wire body can be stored in the threading machine for standby application.

Description

Technical Field

[0001] This application belongs to the field of steel strip threading machine line connection structure, specifically relating to a threading machine line connection structure. Background Technology

[0002] Threading machines, especially steel strip threading machines, are excellent auxiliary tools for pulling guide ropes in pipelines on construction sites. The wear-resistant surface of the steel strip wire body can extend the service life of the threading machine. For example, a wire puller described in US2556484A provides a method to feed a tightly coiled wire body out of a spool by applying driving force to the inner end of the wire body. The wire core gradually expands, and the outer ring continuously engages with the limiting arm in the housing, thereby preventing bending.

[0003] However, in actual use, a section of the thread is always inside the threading machine's housing, while the rest frequently works outside. Because the thread is pulled during operation, it rubs against the inner wall of the conduit. After a period of time, the worn thread loses its tensile strength and needs replacement. Currently, the main method is to remove the outer casing, insert a new thread spool, and tighten the casing. This thread replacement method is relatively complex. Summary of the Invention

[0004] The purpose of this application is to provide a threading machine thread connection structure that enables thread replacement without removing the threading machine housing.

[0005] This application provides a threading machine thread connection structure, including:

[0006] The thread inside the threading machine is divided into two sections: a first thread and a second thread, which are detachably connected. The first thread has a first end face, a first opening, a first protruding edge, a first connecting portion, and a first top surface; the second thread has a second top surface, a second connecting portion, a second concave edge, and a second end face; the first connecting portion is connected to the second connecting portion. The shapes of the first and second connecting portions are matched, and the first connecting portion has space to accommodate the second connecting portion. When replacing the thread, only one of the two sections needs to be replaced; it is not necessary to replace all the threads or the entire thread and spool.

[0007] Furthermore, the first connecting part is rectangular in shape, and the second connecting part is cuboid in shape. The first end face is parallel to the second end face. The first top face is parallel to the second top face. The first opening matches the second concave edge, and the first opening can accommodate the second concave edge; the receiving cavity can accommodate the first convex edge. The regular shape facilitates manufacturing, saves costs, and ensures reliable connection.

[0008] Further, the first line body and the second line body are made of steel. The first line body and / or the second line body are located in the threading machine. The first line body or the second line body located in the threading machine is shorter. If the first line body is located in the threading machine, one end of the first line body is fixedly connected with the reel, and the other end is connected with one end of the second line body. If the second line body is located in the threading machine, one end of the second line body is fixedly connected with the reel, and the other end is connected with one end of the first line body. When changing the line body, only the reel needs to send the line outwards until the connection part of the first line body and the second line body is exposed outside, and then the line body can be changed. After the change, the reel is reeled in by external force, and the changed line body is retracted into the threading machine for standby use. BRIEF DESCRIPTION OF DRAWINGS
