The invention relates to the technical field of ship equipment, and discloses a ship berthing chain stopper which comprises a base, the upper end of the base is movably sleeved with a threaded rod, one end of the threaded rod is fixedly connected with an adjusting nut, and the two sides of the middle of the adjusting nut are in threaded connection with a first nut and a second nut correspondingly. the bottoms of the first nut and the second nut are fixedly connected with speed limiting plates. Through the arrangement of the speed limiting plates and the friction blocks, when anchoring is needed, the speed limiting plates on the two sides move towards the middle by rotating the adjusting nuts, at the moment, the cable lifter can freely rotate for anchoring, the anchor chain can drive the cable lifter to synchronously rotate due to the fact that the protruding blocks clamp the chain links of the anchor chain in the intervals of the protruding blocks, and in the rotating process of the cable lifter, the chain links of the anchor chain are clamped by the friction blocks. The friction blocks stretch out under the action of centrifugal force, once the downslide speed of the anchor chain is too high, the centrifugal force borne by the friction blocks is larger, the friction blocks stretch out more till the friction blocks make contact with and rub against the inner sides of the speed limiting plates, the cable lifter can be decelerated, the rotating speed of the cable lifter is prevented from being too high, and an anchor gear is protected.
本发明涉及船舶设备技术领域,且公开了一种船舶停泊用制链器,包括底座,底座的上端活动套接有螺纹杆,螺纹杆的一端固定连接有调节螺母,调节螺母中部的两侧分别螺纹连接有第一螺母、第二螺母,第一螺母、第二螺母的底部均固定连接有限速板。通过限速板、摩擦块的设置,在需要泊锚时,通过旋转调节螺母使得两侧的限速板向中间移动,此时锚链轮能够自由转动,进行抛锚,由于凸块将锚链链节卡在其间隔中,使得锚链能够带动锚链轮同步转动,在锚链轮旋转过程中,摩擦块在离心力作用下伸出,一旦锚链下滑速度过快,摩擦块所受离心力越大,摩擦块将伸出更多直至与限速板内侧接触并摩擦,能够对锚链轮进行减速,防止锚链轮转速过高,保护锚机。
