Description

An assembled hydropower maintenance platform

technical field

The utility model designs an assembled hydroelectric overhaul platform, specifically an easy-to-disassemble, easy-to-operate and safer overhaul platform suitable for use in narrow and complex spaces in deep well operations and specially used in the field of hydropower.

Background technique

At present, hydropower stations mostly use self-made hanging cages and door cranes for deep well maintenance operations. Operators cannot independently control the lifting of the hanging cages, and often need to communicate with ground control personnel for a long time to reach the best working position, seriously affecting work efficiency; more importantly Unfortunately, most of the self-made hanging cages are simple cage bars, which are connected to the hooks of the door crane through ropes. Without proper safety protection measures, the personal safety of maintenance workers cannot be guaranteed; the only safety measure is to put the hanging cage The six sides are fully enclosed to prevent the staff from accidentally falling from the cage. While avoiding the above-mentioned dangers, this design also limits the operating space of the staff, which brings great inconvenience to the maintenance work; due to the narrow working environment , There are also strict requirements on the size of the hanging basket. In addition, according to the crane safety operating regulations, the door crane cannot be used as a lifting device for people; because the door crane has a large load capacity, the corresponding structure is very thick and firm, which makes loading, unloading and transportation very difficult; moreover, Although the weight of the cage carrying the maintenance personnel is much smaller than the carrying capacity of the door crane, the energy required for the single door crane to work is not reduced, so the cooperation between the cage and the door crane has virtually caused a great waste of energy .

Therefore, it can be said that this field is in urgent need of a maintenance platform with high safety, easy manipulation, disassembly and assembly, and suitable for narrow working conditions to fill the market gap and meet the work needs of the hydropower field, especially to meet the application of deep well operations or similar deep wells in the hydropower field. The operational requirements of the job.

The problem to be solved by this utility model is to provide a kind of hydropower maintenance platform that can make the lifting and receiving devices centrally installed on the upper part of the platform and can be controlled by wireless transmission signals, and is suitable for narrow and complicated spaces, replacing the existing self-made hanging cage The combination of common power or ordinary power on the maintenance platform of the hanging basket has achieved the effect of safe use, easy operation, simple and compact structure, convenient disassembly and transportation.
