Hydraulic lift-type maintenance car

Abstract

The invention belongs to equipment used for maintenance in power industry, in particular to a hydraulic lift-type maintenance car, wherein, a fluid cylinder (7) is vertically arranged at the middle part of a main frame (2); a sprocket shaft bracket (3) is arranged at the upper part of a piston rod of the fluid cylinder (7); a sprocket shaft (5) is arranged on the sprocket shaft bracket (3); a chain wheel (4) is arranged on the sprocket shaft (5); an intermediate cross beam (8) is arranged at the middle part of the main frame (2); a chain guiding wheel (20) is arranged on the intermediate cross beam (8); a guiding frame (18) is arranged on an upper supporting plate cross rack (9) and a lower supporting plate cross rack (11); two pairs of guiding wheels (19) are symmetrically arranged on the guiding frame (18); the guiding wheels (19) slide up and down in guiding grooves formed on the main frame (2); an adjusting screw rod (10) is arranged on the lower supporting plate cross rack (11); a crank (15) is arranged at one end socket of the adjusting screw rod (10); and the chain wheel (4) is connected with the lower supporting plate cross rack (11) by a chain (22) through the chain guiding wheel (20). The hydraulic lift-type maintenance car can move and be locked at will, is safe and reliable to use, reduces the labor intensity of overhaul and maintenance staff, and achieves time conservation and labor conservation.

Description

technical field [0001] The invention belongs to equipment for maintenance in the electric power industry, in particular to a hydraulic lifting maintenance vehicle. Background technique [0002] At present, in the substations currently operating in the power system, there is a metal-clad withdrawable switchgear. During maintenance, the circuit breaker needs to be withdrawn from the cabinet to the ground. Since the original maintenance platform is non-liftable, the circuit breaker is It must be moved to the ground artificially, because the circuit breaker itself is heavy, which is extremely inconvenient for maintenance personnel, laborious and unsafe. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a hydraulic lifting maintenance vehicle that can move freely and save manpower and material resources according to the needs of the site. [0004] The technical scheme adopted by the pr...
