AI Technical Summary
Existing power cable laying equipment has limited traction speed and is not practical enough.
A self-detachable synchronous pressure wheel rotation gear structure was designed. By adjusting the meshing of the driven gear and the driving gear, the traction speed can be changed while the motor speed is constant.
It improves the practicality of power cable laying, and can adjust the traction speed according to needs to meet different laying requirements.
