Technical Field

The invention discloses a spiral lifting cage, belongs to the field of mine transportation, and particularly relates to a cage.

Background

A cage is a lift in a mine for transporting personnel, ore, materials etc., which can generally carry several tons and is used similarly to an elevator.

But compare ordinary elevator, the applied environment of cage is abominable, and the work requirement is higher, so the operation mode of cage and elevator have very big difference, and this kind of difference mainly reflects on the cage lifting means.

Cage lifting requires a lifting derrick to be arranged on a shaft, a lifting motor for providing power and a bottom pit arranged at the lowest end of the shaft. The above-mentioned part area is big, and the cost investment is high, has certain potential safety hazard simultaneously, for example promotes motor operator and does not pay attention to often causing dun jar, overwinding scheduling problem, seriously threatens cage and equipment safety.
