A cable conveying device

Abstract

The invention relates to the technical field of cable installation and transportation, and provides a cable passing through pipe conveying device, which includes a pulling mechanism; a driving mechanism, which is used to drive the pulling mechanism to move in the pipe body; Roller assemblies are provided at the ends; permanent magnets are set between the two roller assemblies on the outside of the pipe string; the roller assembly includes a wheel strut with a uniform ring set on the outside of the string; the end of the wheel strut is provided with a universal wheel . In this way, the present invention provides a wire-drawing mechanism that can move in the tube body, and a driving mechanism outside the tube to drive the wire-drawing mechanism to move; one end of the wire-drawing mechanism is bolted to a pull cord to enter from one port of the tube body and lead out from the other port. Thereby the stay cord is threaded in the pipe body. The other end of the drawstring is bolted to the cable. When the drawstring is passed through the tube body, the drawstring will be pulled out continuously from one end of the tube body, so that the cable will be passed into the tube body, and the cable is in the tube body. threading. The threading efficiency of the cable is improved.

Description

technical field [0001] The invention belongs to the technical field of cable installation and transportation, and in particular relates to a cable transmission device through pipes. Background technique [0002] Usually based on the consideration of electrical safety, the wire needs to be sleeved in the protective tube during installation. The two sockets need to insert the cable into the protective tube. [0003] Generally speaking, in order to save costs, the diameter of the protection tube is usually slightly larger than the outer diameter of the cable, and the cable will inevitably contact the inner wall of the protection tube during socketing. Since both the cable sheath and the protective tube are made of non-metallic materials, the frictional force between the two is relatively large, which increases the difficulty of threading and increases the man-hours for threading. [0004] If the wiring distance is long (especially if the straight line distance is long), multi...

Problems solved by technology

However, in this way, the cables between the protection pipe joints are exposed, which poses a safety hazard, and additional labor is required to repair the connection position, which reduces the work efficiency

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
