Description

Technical Field

[0001] The invention belongs to the field of electric devices, and in particular relates to a hook mechanism for an electric working vehicle. Background Art

[0002] At present, in order to complete the equipment hoisting task safely and efficiently, the substation tubular busbar cannot be shut down.

[0003] In the prior art, when the substation busbar cannot be shut down, the traditional method for lifting equipment is: 1. Manual scaffolding. Because there is no large machinery available, the equipment must be disassembled into small parts with light weight. The personnel then stand on the scaffolding and rely on manpower to transfer and lift the pre-disassembled equipment parts one by one to a high place for installation; the first disadvantage is that it is unsafe. Although the equipment has been disassembled in advance, the conductive part of the knife switch is very heavy, up to 100 kilograms. It is also very laborious for two people to stand opposite to each other to lift and install it. In addition, the upper tube is energized and cannot be used. No protective measures are taken. Once the equipment is dropped from the hands of personnel during lifting, the consequences will be disastrous. Secondly, it is very time-consuming. The erection of scaffolding, dismantling of equipment, and gradual transfer of personnel all affect efficiency. In addition, if the scaffolding is erected over two layers, its stability will be affected. Measures must be taken to prevent tipping and collapse before construction can be carried out. 2: Use an ordinary crane. Since the hook of an ordinary crane is located below the telescopic arm and the hook is large due to counterweight and other reasons, in order to lift the equipment to the predetermined position, the safety distance between the crane telescopic arm and the upper tubular busbar is not enough, and operations cannot be carried out.
