A marine anchor chain jump stop device

The invention discloses a marine anchor chain jump stop device, which comprises a base, a support member and a chain stopper assembly. The chain stopper assembly comprises an arc plate and a flat plate; the arcuate plate is fixedly connected with the plate, and the first surface of the arcuate plate is convex and tangent to the first surface of the plate, and the second surface of the arcuate plate is concave and tangent to the second surface of the plate. The support is connected to the base and is adapted to support the chain stop assembly such that a first face of the arcuate plate is disposed opposite the wheel face of the drive roller. The invention can reduce the phenomenon that the anchor chain jumps out of the driving roller during the circumferential rotation of the driving roller. 本发明公开了种船用锚链止跳装置，包括基座、支撑件、以及挡链组件；挡链组件包括弧形板、以及平板；弧形板与平板固定连接，且弧形板的第面为凸面且与平板的第面相切，弧形板的第二面为凹面且与平板的第二面相切；支撑件与基座连接且适于支撑挡链组件，以使弧形板的第面与驱动滚轮的轮面相对设置。本发明的船用锚链止跳装置，能减少锚链在驱动滚轮上进行圆周转动的过程中跳离驱动滚轮之外的现象。
