Description

Cable threading equipment Technical Field The utility model relates to the technical field of cable threading, in particular to cable threading equipment. Background In power engineering and infrastructure construction, cabling often needs to traverse long and narrow spaces such as pre-buried pipelines, trenches, and the like. Due to the narrow size of the channel, construction staff cannot directly enter the internal operation, and a cable penetrating mode of continuously pushing the cable from one end or pulling the cable from the other end is generally adopted. Due to the fact that the traditional cable penetrating mode lacks buffering, the cable directly generates rigid friction with the inner wall of the channel in the penetrating process, abrasion of the outer surface of the cable wire is increased, the cable wire is clamped and wound in the channel, and accordingly construction efficiency is reduced. Disclosure of utility model Aiming at the technical defects, the utility model aims to provide cable threading equipment which is used for solving the problems that in the prior art, a cable is in direct contact with the inner wall of a channel to generate rigid friction, so that abrasion and clamping winding are increased, and the construction efficiency is finally reduced. The cable threading equipment comprises a fixed ring with a first through hole, wherein the cable is clamped in the first through hole, a rotating ring is rotatably arranged on the periphery of the fixed ring, a plurality of rotating mechanisms for driving the rotating ring to rotate around the fixed ring are arranged on the rotating ring, and the rotating mechanism comprises a plurality of first rollers which are attached to the inner wall of a threading channel.
