The invention relates to a chain type hydraulic hoist special for a coal mine monorail crane, which comprises a power brake assembly, a spline housing of the power brake assembly is connected with a power input shaft of a power speed-reducing torque-increasing assembly, and a power output hoisting traction assembly is arranged on a third planet carrier of the power speed-reducing torque-increasing assembly. And the power braking assembly is connected with the power input assembly. Through hydraulic control and driving, the selected materials meet the coal mine underground operation conditions, the anti-explosion potential safety hazard is avoided, and the lifting device is suitable for lifting of the coal mine underground monorail crane. Meanwhile, safety braking is carried out at the high-speed end of the hydraulic motor, and is superior to low-speed end torque limiting braking commonly adopted in the existing market, and safety and reliability are higher.

    本发明涉及一种煤矿单轨吊专用链式液压葫芦,包括动力制动组件,所述动力制动组件的花键套与动力减速增扭组件的动力输入轴相连接,所述动力减速增扭组件的第三行星架上设置动力输出起吊牵引组件,所述动力制动组件与动力输入组件相连接。本发明通过液压控制和驱动,所选用的材料符合煤矿井下作业条件使用,无防爆安全隐患,适合煤矿井下单轨吊起重使用。同时,在液压马达的高速端进行安全制动,优于现有市场普遍采用的低速端限制扭矩制动,更加安全可靠。
