[0002] In underground mining, tunneling, and other tunneling operations, the tunnel boring machine (TBM), as the core rock-breaking and loading equipment, relies heavily on a stable power supply for normal operation. The cables connecting the TBM to the power supply system not only bear the critical task of transmitting electrical energy but also face the severe challenges of complex operating environments. Tunneling, frequent equipment movement, uneven ground, and potential mechanical collision risks all threaten the safety and lifespan of the cables. Cable guide frames, as specialized equipment for supporting and guiding cables, directly affect the safety, continuity, and economy of tunneling operations.

[0003] However, existing foldable and retractable tunneling machine cable carriers have the following disadvantages:

[0004] (1) Fixed towing frames have a fixed volume and lack folding function. When equipment needs to be moved or underground space is limited, the huge towing frames not only occupy a lot of transportation space, but also require a lot of manpower and resources to disassemble and move.

[0005] (2) The installation of traditional towing frames requires specialized tools and complex processes. The components are not standardized and are difficult to disassemble and replace quickly once damaged, which leads to prolonged equipment downtime and affects the continuity of tunneling operations.

[0006] Therefore, this utility model provides a foldable and retractable cable transfer rack for tunneling machines. Utility Model Content
