The invention relates to the technical field of elevator equipment, and discloses a friction type elevator special for a coal mine. The friction type elevator special for the coal mine comprises a friction roller and two lifting containers, wherein the two lifting containers are fixedly connected through a lifting steel wire, and the lifting steel wire is wound around the surface of the friction roller. According to the friction type elevator special for the coal mine, when the rope is loosened, broken and slipped, the moving speed difference of the lifting containers and a movable pulley is used for triggering a rope braking device to brake the lifting steel wire, a stopping process is more gentle, a safety measure is added on a buffer device, on the other hand, the pressure between a movable roller and a guide roller is determined by load, it is guaranteed that the pressure of the lifting steel wire is kept in a proper range, the damage to lifting steel wire is decreased, secondly, when a hydraulic braking device of the friction roller fails, the rope braking device can be triggered to start to brake the lifting steel wire and further stop the movement of the lifting containers by dragging any position of a speed measuring rope.
本发明涉及提升机设备技术领域,且公开了一种煤矿专用摩擦式提升机,包括摩擦滚筒和两个提升容器,两个所述提升容器通过提升钢丝固定连接,所述提升钢丝缠绕在摩擦滚筒的表面。该煤矿专用摩擦式提升机,在松绳、断绳和打滑时,利用提升容器和动滑轮移动的速度差触动绳索制动装置对提升钢丝进行制动,停止过程中较为平缓,在缓冲装置之上增加了一道安全措施,另一方面,移动辊和导向辊之间的压力由负载决定,保证对提升钢丝的压力保持在适当范围内,减少对提升钢丝的损坏,其次,当摩擦滚筒的液压制动装置失灵的时候,拖动测速绳的任意位置即可触动绳索制动装置启动对提升钢丝进行制动并进一步停止提升容器的移动。
