Four-bundle conductor traveling apparatus of 500kV transmission line

Abstract

The invention relates to a four-bundle conductor traveling apparatus of a 500kV transmission line, which consists of main wheel traveling mechanisms, swing-bar elevation mechanisms, auxiliary wheel traveling mechanisms, brake mechanisms, boom side-swing mechanisms, a suspension basket and the like, wherein the main wheel traveling mechanisms, the swing-bar elevation mechanism, the auxiliary wheeltraveling mechanisms, the brake mechanisms and the boom side-swing mechanisms are respectively divided into two groups which are symmetrically distributed according to the traveling direction of the mechanisms with the left side and the right side being provided with one group respectively, and the main wheel traveling mechanisms, the swing-bar elevation mechanism, the auxiliary wheel traveling mechanisms, the brake mechanisms and the boom side-swing mechanisms are integrated into a whole by hinging two booms and a suspension basket bottom beam on the bottom parts of the main wheel traveling mechanisms. The four-bundle conductor traveling apparatus of the 500kV transmission line has high strength and a light weight, and the weight of the entire apparatus is greatly reduced; high-energy lithium battery is adopted as an electric power source, so the four-bundle conductor traveling apparatus can run continuously for more than one hour after being charged at one time; a direct-current low-speed brushless motor is adopted as a power mechanism, so the electrodeless variable-speed can be realized, and the four-bundle conductor traveling apparatus can be free and smooth to go forward and backward; the conductor traveling apparatus can successfully step across the barriers such as conductor spacers, stockbridge dampers, splicing sleeves, linear suspension strings and the like; and due to the adoption of the brake mechanisms, not only can the brake be realized, but also the safety effect can be realized.

Description

technical field [0001] The invention relates to a 500kV transmission line four-split conductor walking device, which is a transportation tool used for inspection of the 500kV transmission line network frame. Background technique [0002] At present, the inspection of 500kV transmission line grid structure is mainly based on manual routing, and human foot-operated wire flying cars are used on some lines, but these methods have some problems and shortcomings. One is that the wire suspension of the 500kV line is relatively high and the gear span is large. The operation adopts the method of routing or pedal-type wire speeding, which consumes a lot of physical strength of the operators, especially when climbing slopes. During the inspection and operation process of the entire transmission grid, the labor intensity of the operators increases and the work efficiency is low; secondly, the operators cannot stand on the flying car to repair the defects of the wires, and there is a lar...

Problems solved by technology

One is that the wire suspension of the 500kV line is relatively high, and the gear distance is relatively large. The operation adopts wire routing or pedal-type wire speeding, etc., which consumes a lot of physical strength for the operators, especially when climbing slopes.

During the inspection and operation process of the entire transmission grid, the labor intensity of the operators increases and the work efficiency is low; secondly, the operators cannot stand on the flying car to repair the defects of the wires, and there is a large space limitation for the elimination of defects Problems; the third is that the inspection and operation on the transmission line are all dependent on manpower, and the types and quantities of tools carried by the operators are limited, which cannot be solved in time when some special situations are encountered; the fourth is that the operators Walking wires or pedaling wire speeding, the stability of the operation process is poor, and the difficulty and risk are relatively high
