Description

Technical Field

[0001] The present application relates to the technical field of maintenance equipment for power transmission lines, and more specifically, to an anti-slip device for pole climbing operations in winter. Background Art

[0002] In the operation and management of transmission lines, when encountering severe weather such as rain and snow, due to the slippery surface of concrete poles, emergency repair work can usually only be carried out using lifting plates. Although this can solve the problem of the slippery surface of concrete poles, the lifting plates are inconvenient to carry, which affects work efficiency.

[0003] The document with prior art publication number CN102294109A provides a new type of pole climbing foot buckle. The device adds an anti-slip cover and an anti-slip cover on the basis of the traditional pole climbing foot buckle, thereby improving the safety of using the pole climbing foot buckle in bad weather and solving the problem of inconvenient carrying of the lifting plate. The device has the advantages of simple structure, strong practicality, good anti-slip performance and high reliability.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: since the device cannot be switched according to the state of the concrete pole surface, the anti-slip cover and anti-slip cover set in the device, although they meet the anti-slip requirements, will cause damage to the surface of the concrete pole if used multiple times on wet or ice-covered concrete poles.

[0005] In view of this, we propose an anti-slip device for pole climbing operations in winter. Utility Model Content
