Description

[0002] With the development of economic society and the growth of power users, the contradiction between infrastructure construction excavation and cable safe operation is increasingly intense, and the number and length of power outages caused by cable external damage are increasingly concerned by more people, enterprises, and even governments. Therefore, it is urgent to solve the problem of reducing fault power outages. In order to reduce the fault power outages caused by cable external damage, it is required to reduce the manufacturing time of cable terminal heads and intermediate joints, and the quality requirements are becoming higher and higher. In the manufacturing process of cable terminal heads and intermediate joints, cable main insulation chamfering is crucial.

[0003] At present, the manufacturing personnel often manually chamfer, and the smoothness of chamfering is limited by the temperature on site and the technology of the construction personnel, so it is easy to appear unsmooth, burr, and even serious consequences such as damage to the main insulation layer and scrap of the cable head. In the manufacturing process of the cable head, a large number of problems caused by cable main insulation chamfering not meeting the requirements are found, which poses hidden dangers to the later operation and maintenance of the cable. Therefore, how to effectively solve the problems of low cable chamfering compliance rate and low efficiency has become an important topic.

[0004] In addition, the climate change in Kuitun area of Xinjiang is obvious, which leads to a significant problem, that is, the quality control of manual chamfering is unstable. The climate conditions in Kuitun area are variable, with severe cold in winter and scorching heat in summer. Such temperature changes have a significant impact on the thermal expansion and contraction characteristics of cable materials, making manual chamfering operations face greater challenges. Changes in on-site temperature not only affect the operation feeling of construction personnel, but also directly affect the smoothness and accuracy of chamfering, often leading to unsmooth chamfering, burr, and even serious damage to the main insulation layer of the cable, resulting in scrap of the cable head due to quality problems, increasing material costs and construction time.

[0005] In addition, the technical level of cable construction teams in Kuitun area is uneven, and the opportunities for professional training and skill improvement are limited, which makes it difficult to unify the technical standards of manual chamfering operations. Construction personnel with different technical proficiency levels may not be able to ensure that each cable head chamfering meets the specified standards, thereby causing a series of quality problems. These quality problems not only reduce the efficiency of cable head manufacturing, but also seriously affect the safety and stability of cable lines, causing many inconveniences and safety hazards for later operation and maintenance.

[0006] Therefore, it is urgent to design a cable main insulation chamfering device to solve the problems of unsmooth, burr, and even damage to the main insulation layer and scrap of the cable head caused by manual chamfering of the cable. SUMMARY
