Hydraulic over-obstacle ground wire traveling gear

Abstract

The invention discloses a hydraulic over-obstacle ground wire traveling gear. Main wheel carriers are in an n shape, a main wheel shaft is arranged in the middle of each main wheel carrier, the two ends of each main wheel shaft are connected with the middles of carrier bodies on the two sides of the corresponding main wheel carrier respectively, and a main wheel is connected with each main wheel shaft through a bearing; the two main wheel carriers are arranged in parallel, the upper portions of the main wheel carriers are connected through a top beam, the middles of the main wheel carriers are connected through a main wheel connecting rod, and a brake valve is arranged on the main wheel connecting rod; the top beam is fixedly connected with the upper end of a hydraulic jacking mechanism, the lower end of the hydraulic jacking mechanism is fixedly connected with an auxiliary wheel carrier, auxiliary wheels are installed at the two ends of the auxiliary wheel carrier, and the distance between the auxiliary wheels is larger than that between the main wheels; a stop pin connected with the carrier bodies on the two sides of each main wheel carrier is arranged at the position, located below the corresponding main wheel, of each main wheel carrier and provided with an opening and closing locking mechanism; a seat frame is hinged to the lower end of each main wheel carrier body and provided with a seat, and a pedaling rod is arranged at the lower end of each seat frame. The hydraulic over-obstacle ground wire traveling gear is simple in structure, convenient to operate, light in weight and superior in safety performance, and therefore the work efficiency of overhauling ground wires of an electric transmission line is improved.

Description

Technical field [0001] The invention relates to a hydraulic type obstacle ground wire walking device, which is used for super / ultra-high voltage ground wire inspection and repair, and can smoothly pass obstacles such as anti-vibration hammers and anti-vibration whips on the ground wire. Background technique [0002] When the transmission line, especially the ground wire of the ultra-high voltage transmission line is overhauled, it is necessary to reach the working position along the ground wire. Because the ground line is a single line, people cannot walk directly to reach it. The traditional operation method uses the ground flying car to slide along the line. However, the ground flying car cannot meet the obstacles such as anti-vibration hammer and anti-vibration whip installed on the ground line. If you continue to move forward, you need to dismantle the online facilities and install them when you return. The operation is complicated. Due to the high technical requirements for...

Problems solved by technology

Since the ground wire is a single wire, personnel cannot walk directly to reach it. The traditional operation method uses the ground wire speeder to slide along the line, but when the ground wire speeder encounters obstacles such as anti-vibration hammers and anti-vibration whips installed on the ground wire, it cannot To move forward, the online facilities need to be dismantled and reinstalled when returning from the work, which is a cumbersome operation

Due to the high technical requirements for the installation of anti-vibration facilities, frequent disassembly and assembly may cause adverse effects such as damage, deformation, change of position, and change of anti-vibration characteristics of the anti-vibration facilities; Increased labor intensity of operators and low maintenance efficiency
