Aloft traveling device for ascending height during hot-line work

Abstract

The invention relates to an aloft traveling device for ascending a height during hot-line work. The aloft traveling device comprises a rack body, traveling wheels and connecting holes, wherein the traveling wheels are symmetrically arranged at the upper end of the rack body, and are used for supporting the rack body; and the connecting holes are formed at the two ends of the rack body. The aloft traveling device is characterized by also comprising a seat, a pair of limiting devices, a lifting device, a speed regulation brake device and an anti-falling device, wherein the limiting devices are symmetrically arranged at the lower ends of the traveling wheels; the lifting device is matched with the limiting devices; and the speed regulation brake device is used for controlling the traveling wheels. Instable factors of manual speed control are avoided, the safety and autonomy of an operator are ensured, and the emergency operation of the operator encountering a special condition is facilitated; and when a rope ladder head slides downwards from a high altitude on a conductive ground wire with a great slope, speed can hardly be controlled if only the aloft operator grasps the wire with hands, and particularly in rough topographies such as mountains and canyons, the speed cannot be controlled by utilizing a rope on the ground.

technical field [0001] The invention relates to a high-altitude walking device for liveline work. Background technique [0002] At present, live work is an important indicator to reduce the cost of electric power maintenance. However, the function and structure of commonly used live climbing equipment are relatively simple, which cannot meet the safety requirements and standards of live work, or are inconvenient to use, which makes it easy for staff to work with live work for a long time. Fatigue, which leads to various safety problems. When climbing a height, the head of the climbing soft ladder only uses gravity to limit the position. If the position of the person is tilted or missed, it will cause the person to fall, resulting in personal injury or death.

[0002] At present, live work is an important indicator to reduce the cost of electric power maintenance. However, the function and structure of commonly used live climbing equipment are relatively simple, which cannot meet the safety requirements and standards of live work, or are inconvenient to use, which makes it easy for staff to work with live work for a long time. Fatigue, which leads to various safety problems. When climbing a height, the head of the climbing soft ladder only uses gravity to limit the position. If the position of the person is tilted or missed, it will cause the person to fall, resulting in personal injury or death

The existing high-altitude walking device for live-line work is not equipped with a high-altitude self-locking device. The operator can only lock the sealed door after reaching the air, and open the sealed door before getting off the soft ladder, otherwise the soft ladder head cannot be removed. When going up and down the ladder, there is a danger of falling off the head of the ladder, and there is a danger of falling from the ladder. In addition, the live working ladder is directly hung on the ground wire through two pulleys. Pulling and moving by ropes, when operators work on wires and ground wires, on the one hand, it is difficult to fix them at fixed points, and on the other hand, when they need to move or stop, especially when the wires and ground wires have large sags, they may encounter problems caused by When sliding down from a high place, the soft ladder slides faster and there is a certain degree of danger
