Abstract
Description
Technical Field
[0001] This utility model relates to the field of maintenance rack technology, specifically a power distribution network operation and maintenance maintenance rack. Background Technology
[0002] A power distribution network maintenance and repair scaffold is a specialized support tool used for the inspection and maintenance of power distribution network equipment. It primarily supports workers in performing high-altitude operations, inspections, maintenance, repairs, and replacements of equipment. Typically, a power distribution network includes substations, distribution transformers, circuit breakers, and power lines. The work and maintenance of this equipment often require working at heights, making maintenance and repair scaffolds particularly important.
[0003] For example, a power distribution network operation and maintenance frame, disclosed in CN221682862U, includes a ladder frame. A hinged seat is fixedly installed on one side of the lower end of the ladder frame, and a limit plate is rotatably installed on one side of the hinged seat. A servo motor is fixedly installed at the lower end of the ladder frame, and a transmission rod is installed at the output end of the servo motor. Through the ladder frame, hinged seat, servo motor, second pull rope, and toolbox, during use, the first and second spools on the transmission rod can respectively wind up the first and second pull ropes. The second pull rope pulls the limit plate downwards, simultaneously stretching the return spring, causing the limit plate to abut against the lower right side of the ladder frame, thus forming a stable triangular structure and further improving the stability of the ladder frame. Simultaneously, the first pull rope can pull the toolbox upwards, allowing tools placed inside the toolbox to be lifted, eliminating the need for workers to climb and carry tools.
[0004] The aforementioned patent proposes that the limiting plate abuts against the lower right side of the ladder frame, thereby forming a stable triangular structure and further improving the stability of the ladder frame. At the same time, the first pull rope pulls the toolbox upward, which can lift the tools placed in the toolbox. However, in actual use, the operator needs to bend over to pick up the maintenance tools. The tools are placed at a low position, and frequent bending over will put extra pressure on the waist and back, making it inconvenient to use. Utility Model Content
