A clutch device for an anchor capstan is completed by operating a hand wheel at the top end of a capstan head to rotate a trapezoidal screw rod to enable a clutch body to move up and down. The hand wheel is rotated clockwise, and the screw is driven to rotate clockwise through the flat key. The screw rod and the trapezoidal nut are both left-handed trapezoidal nuts, transmission is achieved through the sliding screw pair, and the nuts drive the clutch plate, the connecting rod and the clutch body to move downwards till the clutch is completely closed. On the contrary, the clutch can be moved upwards by rotating the hand wheel anticlockwise, so that the windlass is separated from the clutch. And the topmost end of the clutch device is provided with an indicating sign for indicating the rotation direction and the action of the corresponding clutch device. And the clutch device is fixed in a sliding bearing of an end cover of the winch through a clutch screw rod. According to the invention, the rotary motion of the hand wheel is converted into the linear motion of the clutch through the transmission of the screw-nut sliding screw pair. The clutch body is arranged in the cable twisting cylinder, the internal space is fully utilized, the structure is compact and reasonable, a hand wheel is convenient to operate, and the requirement of an anchor capstan arranged in a narrow space is met.

    一种锚绞盘用离合装置,通过操纵绞盘头顶端的手轮转动梯形螺杆,使离合器体上下移动来完成的。顺时针转动手轮,通过平键带动螺杆顺时针转动。螺杆和梯形螺母均为左旋梯形螺母,通过滑动螺旋副传动,螺母带动离合器板、连杆和离合器体向下移动,直到完全合上离合器。相反的,逆时针转动手轮即可向上移动离合器,使锚机与离合器脱开。离合装置最顶端有指示标牌,指示旋转方向和对应离合装置动作。离合装置通过离合螺杆固定于绞盘端盖滑动轴承内。本发明通过螺杆螺母滑动螺旋副传动,实现手轮旋转运动转换为离合器的直线运动。离合器体内置于绞缆筒内,充分利用内部空间,结构紧凑合理,手轮操作方便,满足布置在狭小空间内锚绞盘的要求。
