Description

Technical Field

[0001] The utility model relates to the technical field of wire threading equipment, in particular to an electrical wire threader for building pipelines. Background Art

[0002] In modern construction projects, electrical conduits are generally buried in walls and floors in a concealed manner. When the main structure is completed, the electrical conduit threading operation begins. When laying electrical lines, in order to protect the wires and increase their service life, the wires are usually installed in protective pipes. During operation, the protective pipes are first installed, and then the wire bundles formed by multiple wires are passed through the protective pipes. This operation is called threading. Since wires and cables are relatively soft, it is difficult to pass through the wire pipes, so auxiliary methods are required. The traditional threading method is that a worker first passes the steel wire through the pipe, and another worker ties the wire to the end of the steel wire. One worker pulls the steel wire while the other worker passes the wire into the pipe.

[0003] In order to improve the efficiency and quality of threading, relevant technicians have further developed threading equipment that can improve the threading effect and convenience of threading. The existing threading machine connects one end of the electrical installation cable to the traction wire, and uses the traction wire to thread the building electrical installation cable. When the existing building electrical installation threading machine is threading the building electrical installation cable, the threading machine is placed inside the building, and then the traction wire is inserted into the wire tube, and then the electrical installation cable is threaded by pulling it back.

[0004] However, the existing threading device cannot effectively deal with building pipes with corners. It is difficult to continue the threading operation at the bend, resulting in the cable being unable to pass through the pipe with a corner. It takes a lot of extra time to adjust the direction of the thread head of the threader, which is less practical and requires a lot of manpower to adjust the operation, increasing the labor intensity of the staff, making the threading work time-consuming, labor-intensive and inefficient. In addition, the existing threading equipment is usually unable to transfer multiple cables, and multiple repeated threading operations are required to complete the threading of multiple groups of cables. Moreover, due to the poor connection stability of the cables, problems such as disconnection are prone to occur. Utility Model Content
