Cable traction device for threading pipe and method for laying cable through pipe

Abstract

The invention relates to a cable traction device used for conduits. The cable traction device comprises a traction seat (1) and a clamping pipe (6) fixed at one end of the traction seat (1); the excircle of the clamping pipe (6) is connected with a clamp nut (9) through a taper thread, and the outer diameter of the clamping pipe (6) is gradually decreased outwards from the end face of the traction seat (1); two to four openings running through the diameter of the clamping pipe (6) and extending towards the large diameter end of the clamping pipe are formed in the small diameter end of the clamping pipe (6); the other end of the traction seat (1) is connected with a traction head (10) through a traction rope (5); and at least three supporting rollers (2) are uniformly arranged in the circumference direction of the traction seat (1). According to the cable traction device, cables can be paved by workers in the conduits conveniently in a labor-saving manner, the cost of spare parts can also be saved, the cables are protected from being out of order, and the efficiency is increased for enterprises.

Description

technical field [0001] The invention relates to the technical field of installation and laying of electrical cables, in particular to a cable traction device for a threading pipe and a method for laying a cable through the pipe. Background technique [0002] The cable conduit is mainly used to protect the cable. It is often used for the concealed laying of electrical cables. In heavy industrial work sites with harsh environments, the cable conduit also has functions such as dustproof and waterproof. [0003] Currently used threading pipe, when laying the electrical cable in the pipe, the traction rope is first passed through the threading pipe, the other end of the traction rope is connected to the stripped head of the cable to make a joint, and then the joint is waterproofed, and the traction rope is dragged. Bring out the new cable to complete the replacement. There will be many problems in the whole process. The width of the joint is smaller than the diameter of the thre...

AI Technical Summary

Problems solved by technology

There will be many problems in the whole process. The width of the joint is smaller than the diameter of the threading pipe, which requires more time and effort for the operator; if the joint is not well made, it is easy to loosen during the dragging process, and a second rework is required; because there will be water vapor in the threading pipe , dust, burrs, etc., will inevitably cause damage to the cable, resulting in potential safety hazards during the use of the cable
