Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and more specifically to a cable laying auxiliary device. Background Technology

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. There are four common methods for cable laying: direct burial, conduit laying, cable trench laying, and cable tunnel laying. Direct burial involves burying the cable directly underground, requiring adherence to certain depth and technical standards. Conduit laying involves placing the cable within a conduit, suitable for cable routing needs in complex environments. Cable trench laying places the cable in a dedicated trench and covers it with protective materials, facilitating maintenance and inspection. Cable tunnels are large cable channels used for the centralized management of large numbers of cables. In addition, indoor cable laying typically uses conduit laying or cable tray laying. When using cable trench laying, to adapt to terrain or building layout requirements, cable trenches often incorporate corners to address changes in cable path direction. These corners can be designed as right angles or bends at specific angles.

[0003] Current technology has shortcomings: at corners, cables are prone to wear and tear on the outer sheath or deformation of the internal conductor due to excessive bending or uneven transitions at corners. This has a detrimental effect on the electrical performance of the cable, reduces its service life, and creates certain safety hazards. Utility Model Content
