AI Technical Summary
Existing wind turbine maintenance tools require frequent changes of different torque wrenches when dealing with bolts of various sizes and types, resulting in cumbersome operation, increased tooling costs and carrying burden, and reduced work efficiency.
A bolt removal torque relief device was designed, comprising a torque wrench, a rotating plate, a ratchet, a pawl, a drive assembly, a quick-release assembly, and a gripping assembly. The quick-release assembly enables rapid replacement of the torque output head, and the combination of carbon fiber reinforced composite material and a high-elasticity memory foam buffer layer improves ease of operation and safety.
It enables quick replacement of bolts of different specifications, reduces the frequency of tool replacement, improves the efficiency of wind turbine maintenance, and reduces operator fatigue and tooling costs.
