Abstract

The invention discloses a cable bending radius controller and a cable bending method. The cable bending radius controller comprises a support rod, a bendable rod, pull ropes and regulating rods, wherein one end part of the support rod is provided with a through hole with an axial line vertical to the axial line of the support rod, scale values are distributed on the support rod along the axial line of the support rod, two sides of the support rod on the scale value are provided with connecting devices, two end parts of the bendable rod are provided with connecting devices for hanging and tensioning, one end of the pull ropes or regulating rods is respectively connected to two ends of the bendable rod, the other ends of the two pull ropes are respectively connected to the connecting device on the scale value of the support rod, and the length of the pull ropes of the regulating rods between the bendable rod and the support rod is equal to the length of the support rod between the corresponding scale value and the bendable rod of the support rod. According to the controller and the cable bending method provided by the invention, the bending radius of the cable can be controlled accurately, and the problem of laying installing quality control of the cable can be effectively solved.

Description

[0001] technical field [0002] The invention relates to a cable bending device, in particular to a cable bending radius controller and a cable bending method. [0003] Background technique [0004] With the continuous deepening of urban cableization, the number of power grid cables in various regions is increasing day by day, and the cable occupies a dominant position in the power grid. The safety of its operation will directly affect the safe and stable operation of the power grid. Therefore, it is urgent to improve the quality of cable engineering. The focus of future project construction. The cable bending radius is an important index to ensure the insulation performance of the cable laying construction and operation. If the bending radius of the cable is less than the specified value during the laying construction or operation, it will directly lead to the destruction of its structure, directly affect its life, and eventually lead to insulation breakdown...

AI Technical Summary

Problems solved by technology

The cable bending radius is an important index to ensure the insulation performance of the cable laying construction and operation. If the bending radius of the cable is less than the specified value during the laying construction or operation, it will directly lead to the destruction of its structure, directly affect its life, and eventually lead to insulation breakdown. , leading to safety and quality accidents, affecting the safe and stable operation of the power grid

[0005] 1. Due to urban planning and historical reasons, the size of cable wells in many places is generally small. How to reasonably arrange the position of cables and control the minimum bending radius of cables is a major problem in engineering construction.

[0006] 2. Due to various factors, the construction of cable projects is now undertaken by the cooperative team. Due to the low professional quality of the cooperative team members and driven by economic interests, etc., the construction of the project is often only about the progress, not about the quality, which leads to Many potential safety and quality hazards, such as: random placement of cables, hard extrusion of cables into the work well, resulting in the bending radius of the cables reserved for the work well cannot meet the requirements, etc.

Cable bending radius is an important indicator to ensure its insulation performance. Too small bending radius will damage its internal structure and directly affect its life. In severe cases, it will directly lead to insulation breakdown and lead to safety and quality accidents.

[0008] 4. The traditional method of measuring the minimum bending radius of cables is to use visual inspection or a tape measure, etc. This method brings large errors, which is easy to cause misjudgment and misjudgment, is not scientific, and is not practical in the process of engineering construction
