AI Technical Summary

Technical Problem

The existing power line tensioning devices lack a self-locking mechanism, which requires workers to constantly hold the strand to prevent it from rotating in the opposite direction, increasing the intensity of their labor.

Method used

A limiting mechanism is adopted, including a clearance groove, adjusting rod, stop block, ratchet and pull block. The limiting mechanism realizes the self-locking of the rotating shaft, so that the rotating shaft can only rotate in one direction, reducing labor intensity.

Benefits of technology

This technology enables unidirectional rotation of the stranding reel, reducing the workload of workers and improving the convenience and safety of operation.
