Problems solved by technology

[0004] 1) The required materials are all on-site materials. It is difficult to fix the corner block firmly, and the block cannot be adjusted in height, so that the bending radius of the cable at the corner cannot be guaranteed, and the cable will be damaged when the pulling force of the traction cable increases.
[0005] 2) If the cable well already has a running cable line, there is a risk of cable damage during operation if the existing cable laying method is used, causing a safety accident
[0006] 3) The construction is not standardized and the process is difficult to control

Abstract

The invention discloses a cable laying guide device for a corner well, which includes a guide skeleton provided with an inner ring and an outer ring, at least three rollers and at least four support feet; Each roller is transversely arranged between an inner ring and an outer ring of the guide frame, each roller is uniformly spaced, each support foot is fixed at the bottom of the inner ring of theguide frame, and the longitudinal axis thereof is staggered with the longitudinal axis of each roller, and the outer ring of the guide frame abuts against an external object. The invention controls the cable radius and stress within the required range in the cable laying operation process, standardizes the cable laying construction process, improves the construction standardization, reduces the cable laying damage risk, and improves the cable safety and prolong the service life.

Description

technical field [0001] The invention relates to the field of cable auxiliary equipment, in particular to a cable laying guide device for corner wells. Background technique [0002] Due to the needs of urban development, the degree of cableization of medium and low voltage distribution network projects in Shunde is increasing day by day. During the cable laying construction process of distribution network construction and renovation projects, the main body of the cable at the corner well position will face corner stretching and bending processes. At this time Horizontal or vertical deflections are subject to bending along the cable delivery path. In general, the structure and material of the cable are allowed to bend within a certain radius range. When the bending radius meets the requirements, the impact on the performance of the cable is within an acceptable range, but when the bending radius is less than a certain value, the insulation of the cable will be damaged. layer ...
