The invention relates to the field of ship equipment, and discloses a chain stopper for a marine ship, which comprises a bearing shaft, two ends of the bearing shaft are respectively and movably sleeved on two supporting plates, the bearing shaft is fixedly sleeved with a chain wheel positioned between the two supporting plates, the supporting plates are provided with longitudinal sliding grooves positioned above the chain wheel, and the longitudinal sliding grooves are communicated with the bearing shaft. A braking gate plate capable of moving longitudinally is arranged in the longitudinal sliding groove, the two sides of the braking gate plate are in friction connection with the two sides of the inner wall of the longitudinal sliding groove respectively, and the middle of the braking gate plate is movably sleeved with a limiting shaft. Through the structural design that the linkage plate is in linkage with the brake flashboard and the pre-brake device, the pre-brake device brakes rotation of the chain wheel before the brake flashboard makes contact with the anchor chain, so that the chain wheel is used for pre-braking the anchor chain, and after the brake flashboard makes contact with the anchor chain, the brake flashboard is matched with the brake flashboard to brake the anchor chain; the problem that the service life of the anchor chain and the chain stopper is affected due to the fact that friction loss caused by releasing or withdrawing of the anchor chain is large is solved.

    本发明涉及船舶设备领域,且公开了一种用于海上船舶的制链器,包括承载轴,承载轴的两端分别活动套装在两个支载板上,承载轴上固定套装有位于两个支载板之间的链轮,所述支载板上开设有位于链轮上方的纵向滑槽,且纵向滑槽内设有可纵向移动的制动闸板,所述制动闸板的两侧分别与纵向滑槽内壁的两侧摩擦连接,且制动闸板的中部活动套装有限定轴。通过联动板联动制动闸板和预制动装置的结构设计,使得预制动装置在制动闸板接触锚链前,就对链轮的旋转进行制动,从而利用链轮对锚链进行预制动,至制动闸板接触锚链后,配合制动闸板一起对锚链进行制动,避免锚链与释放或收回造成的摩擦损耗较大,影响锚链和制链器的使用寿命问题。
