[0001] The invention relates to the technical field of power transmission line detection auxiliary equipment, in particular to a light multifunctional hanging chair for helicopter online operations. Background Art

[0002] Once the UHV power grid is put into operation, it is difficult to shut down for maintenance. Therefore, live maintenance work, as an important technical means for the operation and maintenance of the UHV power grid, is of great significance to ensure the safe, stable and reliable operation of the UHV power grid.

[0003] Live-line maintenance by helicopter uses helicopters to deliver maintenance personnel directly to the defective part of the line, and performs maintenance work without shutting down the transmission line, which not only improves work efficiency but also ensures the safety of maintenance personnel. In the emergency state of the power grid, live-line maintenance on lines in remote and complex terrains has obvious advantages. Compared with traditional manual live-line maintenance, it is fast, efficient and high-tech, and represents the highest level of current international live-line maintenance technology for transmission lines.

[0004] According to the operation method, the live maintenance technology of helicopters can be divided into three types: platform method, sling method and hanging basket method. Among them, the sling method has high on-site operation efficiency, fast speed of equipotential entering and exiting the strong electric field, and is not restricted by the arrangement of the ground wire. However, during the operation of the sling method, due to the limitation of the suspension point of the single hanging chair, the staff can only carry some simple and lightweight maintenance tools with them. In addition, the riding comfort of the operators is not good, and sometimes there are safety hazards, which increases the difficulty of the operators' work. In addition, the sling is made of high-density steel, and the overall weight is large, which is not conducive to its preparation, deployment, inspection and relocation. Summary of the invention
