The invention discloses a safety protection device for mine hoist and a protection method, and belongs to the field of passenger protection devices for mine hoists. The top end of a sleeve I is fixedly connected to the lower end of a top plate; a screw I is in threaded connection with the sleeve I; a safety vest is fixedly connected to the side surfaces of the screw I and the sleeve II through bonding; the lower end of a sleeve II is in threaded connection with a screw II; safety pants are fixedly connected to the screw rod II through bonding; and a warning device comprises a warning lamp, a wire, two conductive blocks I, a conductive block II and a power supply. When a box body falls accidentally, the falling speed of the box body is reduced slowly through double speed reduction until thebox body stops falling, passengers in the box body are prevented from being hurt by sudden stop of the box body, and the passengers can be lifted up through the protection device to be separated froma bottom plate; and meanwhile, a spring I and a spring II provide shock absorption for the passengers, harm to the passengers due to huge impact force generated when the box body falls and makes contact with the bottom face of a hoistway is reduced.
一种矿井提升机用安全保护装置及保护方法,属于矿井提升机乘客保护装置领域。所述套筒Ⅰ的顶端固定连接在顶板下端;所述螺杆Ⅰ的与套筒Ⅰ螺纹连接;所述安全背心通过粘合固定连接在螺杆Ⅰ和套筒Ⅱ的侧面;所述套筒Ⅱ的下端通过螺纹连接有螺杆Ⅱ;所述安全裤通过粘合固定连接在螺杆Ⅱ上;所述警示装置包括警示灯、导线、两个导电块Ⅰ、导电块Ⅱ、电源。在箱体意外下坠时,通过双重减速缓慢降低箱体的下坠速度直至停止,防止箱体突然停止对箱体内的乘客造成伤害,并且本装置还能通过保护装置将乘客提起,使乘客脱离底板,同时弹簧Ⅰ、弹簧Ⅱ为乘客提供减震,减少箱体下坠与井道底面接触造成的巨大冲击力对乘客造成伤害。
