Lifting device for power transmission line strain clamp detection equipment

Abstract

The invention discloses a lifting device for power transmission line strain clamp detection equipment. The lifting device comprises a base, a lower disc connected to the base, an upper disc capable of rotating relative to the lower disc, a telescopic rod with one end hinged to the upper disc, a tackle arranged at the other end of the telescopic rod, a hand rope connected to the tackle, a supporting outer pipe and a supporting inner pipe in threaded connection in the supporting outer pipe. The free end of the inner supporting pipe is hinged to the telescopic rod, the free end of the outer supporting pipe is provided with a suction cup, and the suction cup is adsorbed to the upper disc. According to the lifting device for the power transmission line strain clamp detection equipment, by adjusting the orientation, angle and height of the telescopic rod, operation is convenient, fast and efficient, the structural stability is high, multi-direction lifting can be achieved, convenience is brought to operators, the labor intensity of the operators is greatly relieved, the working time of the operators is greatly shortened, and the safety of working equipment is improved.

Description

technical field [0001] The invention relates to the technical field of hoisting devices, in particular to a hoisting device for testing equipment for tension clamps of power transmission lines. Background technique [0002] The crimping quality of the tension clamp of the transmission line directly affects the safe operation of the transmission line. Since crimping is a hidden project, there are few methods to identify the quality of crimping during acceptance and operation. At present, the newly developed X-ray inspection technology can find internal defects of crimping tubes. The specific detection method is that the operator enters the wire side along the tension insulator, and lifts the X-ray detection equipment to a place 0.5 meters below the tension clamp by using a tackle and a hand rope. The weight of the equipment is about 20 kg, and due to the special structure , worth hundreds of thousands, the operators are very careful when working, it is difficult to lift the ...
