Abstract

An underwater chain stopper comprises a chain stopper support, a roller and a switch blade frame, the switch blade frame is arranged in the middle of the chain stopper support, the roller is arranged on the rear side of the switch blade frame, and two switch blades are arranged on the front side of the switch blade frame. The roller is positioned in the middle of the chain stopper bracket, and is rotationally matched with the chain stopper bracket through a roller shaft; an anchor chain channel is arranged in the middle of the knife switch frame. The left side and the right side of the knife switch frame are each provided with a tensioning oil cylinder, cylinder bodies of the tensioning oil cylinders are fixedly connected with the chain stopper support, and piston rods of the tensioning oil cylinders are in transmission fit with the knife switch frame through knife switch frame connecting blocks. Two knife switch overturning oil cylinders are symmetrically arranged at the top of the knife switch frame, cylinder bodies of the knife switch overturning oil cylinders are fixedly connected with the knife switch frame, and piston rods of the knife switch overturning oil cylinders are in transmission fit with the knife switches on the corresponding sides of the knife switch overturning oil cylinders. According to the underwater chain stopper, the turnover oil cylinder automatically controls the switch blade to be opened and closed, operation is safer and more convenient, and underwater work can be well adapted.

Description

technical field [0001] The invention relates to an anchor chain clamping device, in particular to an underwater chain catcher, which is particularly suitable for clamping the anchor chain after the ship sails or anchors. Background technique [0002] The chain catcher is mainly used to clamp the anchor chain after the ship sails or breaks down. After the anchor breaks down, the chain catcher on the brake can transmit the pulling force of the anchor chain to the hull so that the windlass is not under stress; when sailing, the chain catcher Bear the weight of the anchor and part of the anchor chain to ensure that the anchor is always fixed at the anchor hole and avoid collision between the anchor and the anchor hole. Therefore, the rationality of its structure is directly related to the safety performance of the ship. At present, most of the commonly used chain stops need to be manually opened and closed, which is inconvenient to use; The ship's water and underwater chain sto...
