Description

Technical Field

[0001] This utility model relates to the field of power maintenance technology, and in particular to a power operation and maintenance device. Background Technology

[0002] Power operation and maintenance refers to the maintenance of power lines, power operation, and power emergency repairs by professional teams. Substation operation and maintenance personnel will undertake more operation and maintenance tasks, including daily inspections, switching operations, equipment acceptance, and handling of abnormalities and accidents. Currently, the existing maintenance equipment generally refers to ladders, which are used to repair lines or switches that need to be repaired. However, power maintenance requires manual climbing of ladders, and tools must be carried while climbing the ladders, which is time-consuming and laborious. It is also inconvenient to protect maintenance personnel, resulting in certain safety hazards for maintenance personnel and reducing the effectiveness of use.

[0003] Publication (Announcement) No. CN217676713U discloses a power operation and maintenance device, including a receiving shell. A limiting support plate is fixedly connected to the bottom of the receiving shell. Two movable slots are formed in the bottom of the receiving shell, and movable blocks are slidably connected inside the movable slots. An adjusting sleeve block is fixedly connected to the top of the movable support block, and a first adjusting block is fixedly connected to the top of the adjusting sleeve block. A scissor bracket is rotatably connected between the two first adjusting blocks. This utility model utilizes a limiting component to allow the limiting hollow plate, limiting sliding plate, adjusting spring, L-shaped insert, and limiting hole to cooperate. This facilitates the L-shaped insert passing through one of the limiting holes to limit the connecting rotating block, preventing the two mounting arc plates from detaching from the waist of the maintenance personnel. This eliminates the need for manual climbing, protects maintenance personnel, reduces safety hazards, and improves the effectiveness of use.

[0004] While the above solutions can protect maintenance personnel and reduce safety hazards, equipment braking requires multi-point operation and ground support is laborious, and the operation of adjusting and wearing protective equipment for maintenance personnel is troublesome and complicated. Therefore, we propose a power operation and maintenance device. Utility Model Content
