Description

Rotary shaft type elevator system

Technical Field

The utility model relates to the technical field of wind driven generator accessory hoisting, in particular to a rotating shaft type hoisting machine system.

Background

The wind power generation in China is developed at a high speed for 10 years, because the wind power generation is limited by production and design at the moment, the replacement of large-size spare parts on a fan is not considered, the reservation of a cabin hoisting opening is too small, and a good solution is not available for hoisting the large-size spare parts.

For example, many gearbox lubrication systems of fans today have very severe oil leakage from the cooling fan cooling plates, requiring timely replacement. The leakage oil has the following hazards: first, oil leaks, causing an increase in oil usage. After oil leaks, the gear box oil level is low, and oil needs to be timely filled, so that the lubricating oil cost is greatly increased. Secondly, the leaked oil liquid and grease scatter on the bottom surface of the engine room, even on the inner side of the tower barrel and the ladder stand, so that the sliding down and falling risks of the maintenance personnel of the unit are greatly increased, and the personal safety is endangered. Thirdly, the cleaning oil leakage work load is large, the working environment is poor, and labor cost is increased. Fourth, excessive oil leaks, can flow to and be stained with whole tower outside upper portion from the cabin bottom, not only influence pleasing to the eye, and these oil can cause adverse effect to tower life-span in the past to wash tower maintenance cost relatively increases as well. Fifthly, leaked oil is attached to equipment, so that potential safety hazards of electric leakage and false alarm of a sensor are increased. The coverage of leaked oil liquid and oil dirt on equipment is not beneficial to heat dissipation, so that the local temperature of the equipment is easily caused to be too high, even the fire of a cabin is possibly caused, and finally, the fan burnout event is caused.

But existing cooling fan plate sizes are: 920mm is multiplied by 920mm, and the hoist and mount mouth size is: 600mm by 600mm, the replacement of spare parts at the hoisting hole position can not be carried out by using a crane, so that improvement exists.
