The geological coring winch comprises a driving machine, a roller, a hydraulic control system and a manual clutch, the manual clutch is axially pushed towards the direction of the roller, so that a shaft of the driving machine is separated from a shaft sleeve of the clutch, at the moment, the roller can drive a hydraulic bidirectional gear pump to freely rotate, and the hydraulic bidirectional gear pump is driven to rotate freely; the steel wire rope is freely lowered, loads are balanced through a hydraulic control system, gravitational potential energy is recycled, and the recycled gravitational potential energy is used for providing power for other mechanisms; the pump speed of a hydraulic two-way gear pump in the hydraulic control system is constant, and the load is lowered at a constant speed.
本发明公开一种可回收重力的液压无动力控制放绳的地质取心绞车,包括驱动机、滚筒、液压控制系统和手动离合器,将手动离合器轴向往滚筒方向推动,使驱动机的轴和离合器的轴套分离,此时滚筒可以带动液压双向齿轮泵自由转动,钢丝绳自由下放,通过液压控制系统平衡负载并回收重力势能,将回收的重力势能用于为其他机构提供动力;液压控制系统中液压双向齿轮泵的泵速恒定,实现负载匀速下降。
