Description

Paying-off device for electric power installation Technical Field The utility model relates to the technical field of electric power installation, in particular to a paying-off device for electric power installation. Background In the electric power installation engineering, the pay-off device is used as key equipment, and the performance of the pay-off device directly influences the construction efficiency and quality. At present, the traditional paying-off device adopts a single-station fixed clamping structure, and only can pay-off operation on a single bundle of cables, so that the requirement of multi-wire-bundle synchronous laying in large-scale power construction is difficult to meet. In addition, the clamping mechanism of the existing device often lacks self-adaptive adjustment capability, and when facing coils with different specifications, the clamping mechanism needs to be frequently replaced or manually adjusted, so that the existing device is complex in operation, unstable in clamping and affects paying-off precision and efficiency.
