Abstract

The invention relates to a tower bolt loosening device which comprises a body, a handle, a bolt sleeve, a guide pipe, a connecting rod and a lock hook cable clamp. One end of the body is connected with the bolt sleeve, and the other end of the body is connected with the handle. The body is connected with the guide pipe. The connecting rod is sleeved with the guide pipe. One end of the connecting rod stretches out of the guide pipe, and the other end of the connecting rod is fixed to the lock hook cable clamp. By means of the tower bolt loosening device, the problem that a rusted bolt cannot be demounted easily during construction of working personnel on a tower is solved, the old-fashioned technology that a wrench is held by hands and a steel saw is used for cutting is changed, the working efficiency of field operation is improved, and the labor intensity of the working personnel is lowered.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission and distribution, and particularly relates to a tower bolt loosener for dismantling the tower bolts used on transmission and distribution line towers. Background technique [0002] Because the coastal areas are in areas with high salinity and alkalinity, the bolts on the tower equipment are usually designed with iron and galvanized, which are easy to rust and difficult to disassemble during the operation and maintenance process. It is usually disassembled by sawing and crushing. The method of sawing is time-consuming and labor-intensive. Instruments for breaking bolts are expensive and easily damaged. SUMMARY OF THE INVENTION [0003] Aiming at the above-mentioned problems in the prior art, the present invention develops a new type of tower bolt loosener, which solves the problems of the prior art that the bolts are easy to corrode and difficult to disassemble. [0004] Th...
