The invention relates to a built-in type compact hydraulic winch which comprises a winding drum. The rack comprises a first rack and a second rack which are arranged at an interval; a hydraulic motor; the supporting seat is rotationally arranged on the second rack, and the supporting seat extends into the winding drum from the second mounting port of the winding drum and is fixedly connected with the inner wall of the winding drum; the two-stage planetary reduction mechanism comprises a first-stage planetary reduction gear set and a second-stage planetary reduction gear set which are sequentially arranged in the axial direction. The inner end of the hydraulic motor is rotationally connected with the inner wall of the first mounting port of the winding drum through a first rolling bearing, a first circular bead is constructed on the peripheral wall of the inner end of the hydraulic motor, and the first rolling bearing is arranged at the inner end of the hydraulic motor in a sleeving mode and abuts against the first circular bead through a spacer bush arranged at the inner end of the hydraulic motor in a sleeving mode; the spacer bush is limited in the axial direction through a first check ring clamped at the inner end of the hydraulic motor or a secondary planet carrier fixed to the inner end of the hydraulic motor. The hydraulic winch is more compact in structure and convenient to assemble.

    本发明涉及一种内藏式紧凑型液压绞车,包括:卷筒;机架,包括间隔设置的第一机架和第二机架;液压马达;支撑座,转动设于第二机架上,该支撑座自卷筒的第二安装端口伸入到卷筒内,并与该卷筒的内壁固定连接;两级行星减速机构,包括沿轴向依次设置的一级行星减速齿轮组和二级行星减速齿轮组;液压马达的内端与卷筒的第一安装端口的内壁之间通过第一滚动轴承转动连接,液压马达的内端的外周壁构造出第一台肩,第一滚动轴承套设在液压马达的内端,并通过套设在液压马达内端的隔套抵压在第一台肩上,隔套通过卡设在液压马达内端上的第一挡圈或者固定在液压马达内端上的二级行星轮架在轴向上进行限位。该液压绞车结构更加紧凑,且能方便进行装配。
