A multi-working-condition switching device for a marine winch comprises a main shaft, a left first spline housing, a left second spline housing, a friction plate, a right first spline housing, a right second spline housing, a hydraulic piston cylinder and a double-channel rotating connector. The left first spline housing, the left second spline housing, the right first spline housing and the right second spline housing are sequentially connected and then sleeved on the spindle, the friction plate is mounted in the spline housing, the right first spline housing and the right second spline housing are connected and sleeved on the spindle in an empty manner, one end is connected with the friction plate, and the other end is connected with the speed reducer through an external spline. The hydraulic piston cylinder is installed in the second right spline housing and the second left spline housing, and the double-channel rotating connector is installed at one end of the main shaft and fixed to the base or the support through the brake device. The device can meet the design requirements of complex working conditions of a single winch; an emergency release function when the steel wire rope is loaded can be realized; and the axial size of the winch is shortened.
一种船用绞车用多工况切换装置,包括主轴、左第一套花键壳、左第二花键壳、摩擦片、右第一花键套、右第二花键套、液压活塞缸和双通道旋转接头,主轴安装于绞车底座或支架上,左第一套花键壳、左第二花键壳、右第一花键套和右第二花键套依次连接后套接于主轴上,摩擦片安装于花键壳内,右第一花键套和右第二花键套相连空套在主轴上,一端与摩擦片连接,其另一端通过外花键与减速装置连接,液压活塞缸安装于右第二花键套和左第二花键壳内,双通道旋转接头安装在主轴的一端,通过制动装置固定在底座或支架上。该装置可以满足单台绞车复杂工况的设计要求;可以实现钢丝绳带载时的应急释放功能;缩短了绞车的轴向尺寸。
