The invention relates to a novel hydraulic hoist for a coal mine, which comprises a first-stage deceleration brake part, one end of the first-stage deceleration brake part is connected with a hydraulic drive control part, and the other end of the first-stage deceleration brake part is connected with a planetary reducer through a power input shaft. And a planet carrier of the planetary reducer is inserted into a chain wheel of the power output part. 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用新型液压葫芦,包括一级减速制动部分,所述一级减速制动部分一端与液压驱动控制部分相连接,所述一级减速制动部分的另一端通过动力输入轴与行星减速器相连接,所述行星减速器的行星架插入动力输出部分的链轮中。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。
