The invention discloses a hydraulic winch which comprises a winding drum assembly, a power mechanism and a piston sleeve assembly, and a separated transmission part is connected into the winding drum assembly; the power mechanism is in transmission connection with the separated transmission part, and a piston rod of the piston sleeve assembly is rotationally connected with the separated transmission part; and the other end of the piston rod extends out of the piston sleeve assembly and forms an axial limiting mechanism, the piston sleeve assembly is further provided with a movable clamping mechanism, and the movable clamping mechanism can be clamped with the axial limiting mechanism so that the separated transmission part and the winding drum assembly can keep transmission connection or transmission separation. The piston rod is used for driving the separated transmission part to achieve transmission connection or transmission separation with the winding drum assembly, so that free switching of a hydraulic transmission mode or a free rotation mode of the winding drum assembly is achieved, the use requirements of different working conditions are met through two different working modes, the working modes are diversified, the applicability is wider, and the piston rod is clamped through the movable clamping mechanism, so that the stability of a transmission working mode is ensured.
本发明公开了一种液压绞车,包括卷筒组件、动力机构和活塞套组件,卷筒组件内连接有分离式传动件;动力机构与分离式传动件传动连接,活塞套组件的活塞杆与分离式传动件转动连接;活塞杆另一端伸出活塞套组件并形成有轴向限位机构,活塞套组件还设置有活动卡紧机构,活动卡紧机构可与轴向限位机构卡合以使分离式传动件与卷筒组件保持传动连接或传动分离。本发明利用活塞杆带动分离式传动件实现与卷筒组件的传动连接或传动分离,从而实现卷筒组件液压传动或自由转动模式的自由切换,利用两种不同的工作方式满足不同工况的使用需求,工作方式多样化,适用性更广,且活塞杆通过活动卡紧机构实现卡紧,确保传动工作方式的稳定性。
