Turning roller set

Abstract

A wheeling roller group includes a strip bracket and a plurality of rollers. The radial section of the strip bracket is concave; the rollers are arranged on the bottom surface and the side walls of the bracket; the axes of the rollers on the bottom surface of the bracket are vertical to the side walls of the bracket; and the axes of the rollers on the side walls of the bracket are vertical to thebottom surface of the bracket. The invention has the advantages that various combination manners are adopted to manufacture the combined bracket and the rollers; different arrangement methods are used in different environments; the use space of the rollers can be ensured; the structural rigidity of the rocket bracket can be met; and the bracket is installed and fixed according to the technical requirements of cable laying. The side draw of the pull can be reduced, the mechanical strength can be reduced, and the safety of cables can be ensured. The roller group is suitable for environments with complicated geographical positions for perpendicular throw laying and horizontal transformation laying.

Description

technical field [0001] The invention belongs to the technical field of power circuits, in particular to a turning roller set used for laying power cables with enlarged cross-sections. Background technique [0002] In the prior art, the continuous use of large cross-section power cables in the development of electric power, how to deal with the cables during the laying process without mechanical damage is the basic guarantee for the long-term safe operation of the cables. For example, when laying the drop, it can be solved by combining manual and mechanical methods in the past, but now the cable is heavy (generally up to 36kg / m) and artificial construction cannot be realized at all, and mechanical tools will also cause great damage to the cable; another example , When laying in a horizontal light bend, the pulling force on the whole line itself is very large, and the pulling force and side pulling force on the turning cable are unimaginable. The method of supporting it with w...
