Multifunctional high-voltage cable hoisting and laying guide arm and laying method thereof

Abstract

A multifunctional high-voltage cable hoisting and laying guide arm comprises a revolving body assembly providing a revolving effect, a stand column assembly providing a supporting effect, a folding arm assembly, a multi-stage telescopic arm assembly, an auxiliary lengthening arm, a hanging basket assembly for an operator to work high above the ground and a control device. The lower part of the revolving body assembly is fixed on an external movable vehicle body, the upper end of the revolving body assembly is fixed at the lower end of the stand column assembly; the two ends of the folding armassembly are hinged to the fixed stand column assembly and the multi-stage telescopic arm assembly correspondingly. A folding control oil cylinder is arranged between the folding arm assembly and therevolving body assembly or the stand column assembly, a folding arm oil cylinder is fixedly installed at one side of the folding arm assembly, the telescopic end of the folding arm oil cylinder is fixed to a multi-stage telescopic arm oil cylinder lug, a multi-stage telescopic arm built-in oil cylinder drives the telescopic arm to stretch out and draw back, and the front end of the auxiliary lengthening arm is fixedly connected with the tail end of the multi-stage telescopic arm assembly. Barrier-free cable laying is achieved, the aerial work requirement is met, auxiliary personnel are reduced, and mechanical work is achieved.

Description

technical field [0001] The present invention relates to railway high-voltage cables, urban rail transit stray cables, and the construction of professional high-voltage cables in the fields of electric power, substation, and contact network in the field of national grid construction. It is a guide arm for lifting and laying high-voltage cables. Background technique [0002] Railway high-voltage cables, urban rail transit stray cables, and national power grid construction fields are specialized in electric power, substation, and catenary. Manually lay high-voltage cables. In the ditch, the laying of high voltage cables is completed. In particular, the length of a single high-voltage cable reel for high-speed railway trunk lines is more than 3,000 meters, and the weight is about 5,000Kg. Due to the constraints of the construction environment and terrain, 3 safety protection personnel are required to protect and 10 workers to rotate the cable reel. According to the erection pos...
