Description

Technical field:

[0001] The invention relates to a hoist multi-rope control system and method, in particular to an ultra-deep mine hoist multi-rope cooperative control system and method. Background technique:

[0002] At present, as my country regards the development of deep resources as an important development strategy, large-scale hoisting equipment for ultra-deep mines has become the key equipment to realize the development of deep resources. Traditional single-rope winding hoists and multi-rope friction hoists Increased effective load rate, lifting efficiency, safety, etc. decline rapidly and cannot be used for ultra-deep well lifting. The multi-rope winding hoist has the characteristics of the first two hoists and has been applied in the field of ultra-deep well hoisting. During the operation of the equipment, there will inevitably be a tilting phenomenon of the container caused by the asynchronous movement between the steel wire ropes; in addition, due to the vibratio...
