Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a bending guide device for cable laying. Background Art

[0002] Laying long-distance cables in cable trenches or tunnels is a critical step in power engineering. The route must be planned and the trench must be cleared before the cable is unrolled from the reel and laid along the predetermined path using a traction machine or manual transport. During the process, tension must be controlled to avoid damage, and tools such as pulleys must be used to reduce friction. Finally, the cables must be fixed, labeled, and quality inspected to ensure safe and stable operation.

[0003] When laying cables, if there is a drop in the laying area, the cables need to be bent. However, the friction between the cables and the trench walls and brackets increases at the bends of the cables, and long-term operation may wear the cable surface. Therefore, a bending guide device for cable laying is proposed to solve the above problem. Utility Model Content
