Manned traveling locomotive for high-voltage transmission line

Abstract

The invention relates to a manned traveling locomotive for a high-voltage transmission line, which mainly utilizes a double-joint eight-arm hanging basket structure. The manned traveling locomotive mainly comprises a frame, a main traveling arm, an auxiliary arm, a power source, a driving mechanism, a control mechanism, a lifting mechanism, and a braking and protecting mechanism. The main traveling arm consists of a joint arm, a traveling wheel, a drive motor and a switching push rod. The auxiliary arm consists of a joint arm, a roller wheel and a pressing rod bar. The driving mechanism consists of a deceleration motor, a change gear and a drive chain. The lifting mechanism consists of a drive sprocket, a takeup and paying-off wheel, an insulating stringer and a manned hanging basket. The braking and protecting mechanism consists of a brake handle with a locking device, a location safety rope with a fixture and a guard bar. The manned traveling locomotive for the high-voltage transmission line, disclosed by the invention, can carry persons to stably and flexibly travel on power-off or power-on high-voltage transmission lines with various spans and sags, can be taken as a movable overhauling work platform of the high-voltage transmission line, and can also be applied to checking and deicing the high-voltage transmission line; in addition, the invention has the advantages of high work efficiency, good work quality and capability of guaranteeing the safety of maintainers.

Description

technical field [0001] The invention relates to a high-voltage transmission line inspection, maintenance, deicing and other maintenance, in particular, a walking locomotive for manned and obstacle-crossing motorized traveling of high-voltage split wires. Background technique [0002] With the rapid development of my country's economy, ultra-high voltage and even ultra-high-voltage large-capacity transmission lines are showing a leapfrog growth trend, and the requirements for the stability of high-voltage power grids are also getting higher and higher. Timely and rapid maintenance and repair of ultra-high voltage lines is the key to ensuring the safety of the power grid. inevitable requirement.

Problems solved by technology

[0003] my country's ultra-high-voltage transmission lines have a long mileage, and most lines pass through mountainous areas, river valleys, forests and other areas. The height difference between line towers is large and the distance is long. The traditional operation method relies on manual climbing and moving or using a wire pulley to manually enter the wire working position. Not only is the work difficult, high-intensity, and low-efficiency, but there are also hidden dangers to the personal safety of the operators.

Although the foreign operation method of using helicopters for ultra-high voltage line maintenance greatly reduces the work intensity and high work efficiency, but in view of my country's current actual national conditions, the helicopter operation method is complicated in the early stage and the overall cost is high. The repair and maintenance of operating equipment There are big problems, and it is difficult to be widely used in China in a short time
