The invention discloses a protective device for mine wellhead manned lifting, and particularly relates to the technical field of mine lifting. The protective device comprises a device base, a verticalwellhead is fixedly formed in the middle of the device base, device supports are fixedly arranged at the two sides of the top of the device base, and a support top plate is fixedly arranged between the tops of the device supports. A driving box body is fixedly arranged at the top of a device top plate, four support mounting plates are fixedly arranged in the driving box body, and a lifting driving shaft is fixedly arranged in the middles of the support mounting plates. A driving oil cylinder pushes a driving rotary disc to drive a rotary shaft to rotate, so that a limiting locking wheel is driven to rotate, passing of a lifting cable is limited, a pressing air cylinder pushes a locking clamping block to press the lifting cable, the state of the lifting cable is fixed, the stability of a manned compartment is improved, and the protection effect of the manned compartment is improved.
本发明公开了一种用于矿井井口升降载人用防护装置,具体涉及矿井升降技术领域,包括装置底座,所述装置底座中部固定设置有竖井口,所述装置底座顶部两侧均固定设置有装置支架,所述装置支架顶部之间固定设置有支架顶板,所述装置顶板顶部固定设置有驱动箱体,所述驱动箱体内部固定设置有支架安装板,所述支架安装板数量设置为四个,所述支架安装板中部固定设置有升降驱动轴。本发明通过驱动油缸推动驱动转盘,带动转动轴进行转动,实现带动限位锁紧轮进行转动,对升降索的通过进行限制,压紧气缸电动锁紧夹块对升降索的压紧,实现对升降索的状态固定,提高载人厢体的稳定性,提高载人厢体的防护效果。
