The invention discloses a coal mine vertical shaft mixed lifting system and relates to the technical field of coal mine transportation, the coal mine vertical shaft mixed lifting system comprises a shaft sinking derrick, a lifting head sheave, platform supporting ribs, reinforcing supporting ribs and a conveying belt, a guide frame is fixedly connected to the inner wall of the shaft sinking derrick, a skip bucket is arranged on the inner wall of the guide frame, and a bent rail is fixedly connected to the inner wall of the shaft sinking derrick; a cage is arranged on the inner wall of the guide frame and located on one side of the skip, and a base is fixedly connected to the lower surface of the guide frame. The acceleration sensor and the cage are started at the same time, when the acceleration of the cage is abnormal, the hydraulic cylinder is started, then the brake pad is attached to the inner wall of the guide frame, friction deceleration is conducted, the cage is stopped, safety is improved, then the pressure of the brake pad is slowly reduced, the cage slowly moves downwards, then the brake pad is locked, and the safety of the cage is improved. The cage falls into the bottom of the coal mine vertical shaft, workers are not prone to being trapped in the air, and safety is achieved.
发明公开了一种煤矿立井混合提升系统,发明涉及煤矿运输技术领域,包括凿井井架、提升天轮、平台支筋、加固支筋和传送带,凿井井架的内壁固定连接有导架,导架的内壁设置有箕斗,凿井井架的内壁固定连接有曲轨,导架的内壁且位于箕斗一侧设置有罐笼,导架的下表面固定连接有底座。本发明,加速度传感器与罐笼同时启动,当罐笼加速度发生异常时,液压缸启动,进而使得刹车片与导架的内壁贴合,进行摩擦减速,进而使得罐笼停止,提升安全性,然后缓缓降低刹车片的压力,使得罐笼缓慢下移,然后锁定刹车片,使得罐笼落入煤矿立井底部,工作人员不易被困在空中,更为安全。
