Description

Technical Field

[0001] The utility model relates to a mining cage, in particular to an automatic cage curtain device for the mining cage. Background Art

[0002] In mine production, cages are key lifting equipment, mainly used for the lifting of auxiliary shafts, carrying personnel, ores, equipment and materials. For medium or small mines, cages can even undertake the lifting tasks of the main shaft. As for cage access switch devices, most of the existing technologies use manual operation. Although the cost is low, it is inconvenient to operate and there are safety risks, such as hand pinching and other injury accidents. The currently common cage automatic rolling shutter doors, although they have improved the degree of automation, often rely on hydraulic power devices, which not only makes the equipment larger and occupies more space, but also relatively expensive, but also has many inconveniences in maintenance.
