Description

An aerial work platform

technical field

The invention relates to a high-altitude operation platform, which belongs to the technical field of high-altitude operation safety tools used for line construction in the electric power industry.

Background technique

During the repair and maintenance of transmission lines in the power industry, due to the high installation height of the equipment, the staff often need to work on the pole tower.

At present, when working on poles and towers, construction workers wear foot buckles to climb the poles. After climbing to the working position, people stand on the foot buckles, and then use the safety belt to connect the pole body to fix the body. In order to ensure that the foot buckles do not fall off, one foot One foot is high, one foot is low, or two foot buckles are buckled at the same height to form a three-point support working state. In these methods, both feet must be kept at the same time. If there is a slight carelessness, there is a danger that the dusty foot buckle will fall off. At this time, the construction personnel The body and the rod body are at a certain angle, and the two feet are always pedaling on the foot buckles and cannot be moved. Not only is the construction operation extremely difficult, the labor intensity is high, and the stability is poor, and there are potential safety hazards, which have caused psychological impact on the construction workers and increased construction difficulty.

In addition, some materials, tools, equipment, etc. that are sometimes needed during pole operations have no place to be placed, and usually need to be carried up and down the pole tower by the staff. After the personnel have bundled up the required items, the construction workers on the pole tower will pull them up one by one, and several staff members will cooperate to hoist them to the construction site to fix them, which wastes construction time, low work efficiency, and increases the workload of the construction staff.
