A device for fast threading of cable elbow sleeves

Abstract

A device for fast threading of cable elbow sleeves. The plastic universal flexible shaft can be bent and deformed in any direction, so that two sliding sleeves can be inserted into the elbow cable sleeve from the left and right ends respectively. The sliding sleeve head The end is beveled, so the two sliding sleeves can be in contact with each other at the corner of the elbow cable sleeve. Since the inner end of the sliding sleeve is open, the cable is inserted from the opening. Since the sliding sleeve is rotated and installed with steel balls, the steel The outer end of the ball rotates to realize rolling friction contact when the sliding sleeve is inserted into the elbow cable sleeve, which facilitates the insertion of the sliding sleeve, and the inner end of the steel ball rotates, which can facilitate the change of sliding friction of the cable into contact with the steel ball at the corner The sliding sleeve realizes the physical isolation between the cable and the cable sleeve of the elbow, reduces the friction resistance of the cable passing through the corner, and reduces the wear and tear when the cable passes through the cable sleeve of the elbow , improved threading efficiency.

Description

technical field [0001] The invention relates to the technical field of cable pipe penetration, in particular to a device for fast threading of cable elbow sleeves. Background technique [0002] At present, when electromechanical equipment manufacturers thread cable casings, they mostly thread them manually. Because there is no bending and large-area contact friction, this method is more practical for straight pipes. However, for bent pipes, because the cables are deformed after bending and rubbed against the pipe wall of the pipe, the resistance of the cables to travel increases, and it takes time and effort for the workers to construct. Abrasion of the protective layer will cause wear and tear of the cable sleeve of the elbow after the cable with a long size is passed through the pipe, which will affect the mechanical strength, airtightness and service life of the sleeve. Contents of the invention [0003] In order to overcome the shortcomings of the above technologies,...

AI Technical Summary

Problems solved by technology

However, for the bent pipe, the deformation of the cable after bending and the friction with the pipe wall of the pipe lead to the increase of the resistance of the cable to pass through, and the construction is time-consuming and laborious for the workers. Causes wear and tear on the protective layer. After the cable with a long size is passed through the pipe, it will even cause wear or even wear through the elbow cable sleeve, which will affect the mechanical strength, airtightness and service life of the sleeve.
