Description

Technical Field

[0001] The utility model relates to the technical field of cable tube threading auxiliary equipment, in particular to a cable protection tube threading device. Background Art

[0002] Cable protection tube is a pipe or casing used to protect cables from external damage. Its main function is to protect cables from mechanical pressure, chemicals, moisture, corrosion, electromagnetic interference and other factors to extend the service life of the cables. According to different materials, cable protection tubes can be divided into plastic cable protection tubes, fiber reinforced composite cable protection tubes and polyurethane cable protection tubes. In addition, according to different installation methods, cable protection tubes can also be divided into buried type, ground type and overhead type; in power systems, cable protection tubes are widely used. For example, in areas where communication cables and power lines intersect, in order to prevent power lines from being broken and causing short circuit accidents, causing communication cables and wire ropes to be electrified, cable protection tubes are usually used to protect cables, switches, movement boards, and even the entire machine from being burned. In addition, the cable protection tube can also play a certain role in isolating the magnetic field interference of the power line. When threading the long-distance cable protection tube, whether using a threader or manual threading, there will be problems with threading jams and blockages at bends. Even at the branch position, it is difficult for the threader to guide the threading of one of the lines in a targeted manner. Therefore, this case hopes to propose a device that can be quickly disassembled and assembled and can guide the direction of insertion to solve the above problems. For the above problems, there may already be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution. Utility Model Content
