Description

Technical Field

[0001] The utility model relates to the technical field of pipeline traction equipment, in particular to an automatic traction device for producing PVC power cable protection pipes. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas.

[0003] At present, polyvinyl chloride, abbreviated as PVC in English, is the third largest synthetic polymer plastic in the world (after polyethylene and polypropylene), with an annual production of about 40 million tons of PVC. PVC is a polymer formed by the polymerization of vinyl chloride monomer (VCM) in the presence of initiators such as peroxides and azo compounds or under the action of light and heat according to the free radical polymerization mechanism. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. During the installation of power cables, protective tubes are required for protection. The material of the protective tubes is often PVC tubes. During the production process of the PVC tubes, a traction device is required to pull the protective tubes out of the molding equipment.

[0004] However, when the current automatic traction device for the production of PVC power cable protection tubes is in use, the cable is often inserted into one end of the protection tube for traction and movement. After use, the worker needs to repeatedly insert the cable, which is rather cumbersome. It is necessary to insert and connect one end of the protection tube, which causes damage to one end of the protection tube. Therefore, the traction end of the protection tube needs to be cut before it can be used, which causes a certain amount of material waste, and the operation is rather troublesome, which increases the workload.
