Description

Cable threading tool convenient for operation in narrow space Technical Field The invention belongs to the technical field of pipeline cable installation tools, and particularly relates to a cable pipe penetrating tool convenient for operation in a narrow space. Background Cabling is a key element in power, communications and construction installation, and in the threading of cable ducts, pre-buried pipes and the interiors of buildings, pipe threading tools such as pipe threading devices, wire threading devices or wire ropes are widely used for guiding cables through preset pipes. At present, most of traditional pipe penetrating tools on the market are of an integrated long rod structure, the whole length of the traditional pipe penetrating tools is long, the rigidity of the traditional pipe penetrating tools is high, when the traditional pipe penetrating tools are required to work in space-limited environments such as cable wells, corners or existing equipment seams, the traditional pipe penetrating tools are difficult to bend, especially in a pipeline turning position or a complex pipeline with a plurality of sections of elbows, the long rod-shaped pipe penetrating tools are extremely easy to be blocked due to too small bending radius, the traditional pipe penetrating tools cannot continue to advance, even the pipeline or the wall is required to be broken and detached, the tools can be taken out, and the construction efficiency is seriously reduced. Secondly, in the poling process, the outer sheath of the cable can be directly contacted with the inner wall of the pipeline, along with the increase of the poling distance, the contact area and positive pressure between the cable and the pipe wall are increased, so that the friction resistance is increased sharply, the poling difficulty is increased, the outer sheath of the cable is easy to wear and scratch due to long-time friction, and even the insulating layer is damaged, so that hidden danger is buried for safe operation of the cable. The invention patent of 202511671345.4 discloses a cable poling instrument convenient to narrow and small space operation, including cable installation section of thick bamboo, encapsulation section of thick bamboo and guide cylinder, the cable installation section of thick bamboo sets up the one end at encapsulation section of thick bamboo, and the guide cylinder is installed at the other end of encapsulation section of thick bamboo, and the cable installation section of thick bamboo is used for centre gripping cable end, and the guide cylinder is used for direction and ground breaking. The clamping-guiding-breaking integrated structure is suitable for short-distance operation in narrow operation spaces such as underground pipe network wells, wall embedded pipelines, equipment dense areas and the like, and solves the problems of blocked operation, unstable clamping and foreign object blocking, advancing and blocking of the traditional tool. However, the integrated long rod structure is not suitable for operation in a bent pipeline, and the problem of friction between a cable and a pipe wall in the long-distance pipe penetrating process cannot be solved. Disclosure of Invention The invention aims to overcome the defects of the prior art, and provides a cable pipe penetrating tool convenient for operation in a narrow space, which can flexibly pass through a narrow space and a bent pipeline, protect and guide a cable in the pipe penetrating process and effectively reduce friction damage between the cable and the pipe wall. The cable pipe penetrating tool convenient for operation in a narrow space comprises a traction driving part, an end connecting part and a plurality of support protecting parts, wherein the traction driving part is connected with the end connecting part through a traction rope; The traction driving part is provided with a driving roller assembly and a stabilizing roller assembly, the driving roller assembly is used for driving the traction driving part to move in the pipeline, and the stabilizing roller assembly is used for limiting, guiding and stabilizing the traction driving part by pressing a stabilizing roller arranged on the stabilizing roller assembly against the inner wall of the pipeline; The end connecting part is used for carrying out locking and fixing connection on the end part of the cable to be penetrated through by a locking and fixing assembly arranged on the end connecting part; the support protection part is used for winding on the cable to be penetrated and supporting and protecting the cable to be penetrated through a plurality of universal balls arranged on the support protection part, so that the cable to be penetrated is prevented from being in long-distance friction contact with a pipeline. Further, the traction driving part further comprises a supporting main board, the driving roller assembly comprises supporting side boards arranged at the bottom of the supporting main board, a fi
