Cable reels, as the main equipment for cable storage and transportation, have a direct impact on construction efficiency and cable quality due to their reasonable design and stable laying. Traditional cable reel laying technology is mostly manual operation, relying on the experience and technical level of the operator, and has problems such as difficulty in operation, low efficiency, and difficulty in ensuring safety.

[0003] The existing power line construction laying device is cumbersome to disassemble and replace the wire reel. The existing one is usually fixed with bolts on the rotating shaft, which is easy to be damaged by vibration. Or there is a U-shaped slot clamping wire reel without other fixing methods. The road is tilted or bumpy, which can easily cause the wire reel to fall off as a whole, damaging the wires on the reel, and making it difficult to ensure safety. On the other hand, after stopping the laying of the wire, due to inertia, the wire reel will continue to lay out the wire for a certain distance, causing the wire to rotate out of the vehicle body, making the wires messy, and it is necessary to turn the crank to reel in the wires. If the wires are not combed, it is easy for the wires to become tangled or touch sharp solids to damage the wires, resulting in reduced construction efficiency.
