The multi-rope friction type mine hoist comprises a friction wheel and a head sheave, a steel wire rope surrounds the friction wheel and the head sheave, hoisting containers are arranged at the two ends of the steel wire rope respectively, tail ropes are arranged at the bottoms of the hoisting containers, the two ends of the tail ropes are connected to the hoisting containers respectively, and an anti-slip device is arranged on the front side of the friction wheel. And the steel wire rope penetrates through the anti-slip device. The invention belongs to the technical field of mine hoists. The friction wheel hub is attached to the steel wire rope, when the slipping steel wire rope slides rapidly, the rotating speed of the friction wheel hub is increased, the centrifugal force of the speed measuring sliding block on the friction wheel hub is increased, the connecting rod is driven to move outwards, the connecting rod drives the poke rod to move, and the poke rod pushes friction wedge blocks on the two sides of the rope clamping plate to get close to the limiting block; the rope clamping plate is extruded by the limiting block to be clamped on the steel wire rope, and gradually-increased friction force between the rope clamping plate and the steel wire rope prevents the steel wire rope from further slipping to cause equipment damage or accidents.

    本发明公开了一种多绳摩擦式矿井提升机,包括摩擦轮和天轮,钢丝绳围绕在摩擦轮和天轮上,钢丝绳两端分别设有提升容器,提升容器底部设有尾绳,尾绳两端分别连接在提升容器上,所述摩擦轮前侧设有防打滑装置,所述钢丝绳穿过防打滑装置。本发明属于矿井提升机技术领域;本发明通过将摩擦轮毂贴合在钢丝绳上,当出现打滑钢丝绳快速滑动时,摩擦轮毂转速增加,摩擦轮毂上的测速滑块离心力增加,并带动连接杆向外侧移动,连接杆带动拨动杆移动,拨动杆推动绳索夹板两侧的摩擦楔块靠近限位块,绳索夹板受到限位块的挤压夹持在钢丝绳上,绳索夹板与钢丝绳之间逐渐增大的摩擦力,防止钢丝绳进一步打滑,导致设备损坏或事故发生。
