AI Technical Summary
The current method of laying rail transit cables is labor-intensive and inefficient, making it difficult to achieve the standard triangular arrangement of three cables, and easily resulting in problems such as twisting, knotting and uneven wiring.
A cable laying device for rail transit was designed. It uses a drive wheel to drive a rotating wheel and a transmission assembly to achieve synchronous rotation of the cable reel. The guide groove and guide bar ensure that the cable is arranged in a triangular shape, reducing manual operation.
It improves cable laying efficiency, ensures neat cable arrangement, reduces manpower requirements and on-site coordination difficulties, and enhances the stability and safety of cable laying.
