Problems solved by technology

[0004] But this application clamps the anchor chain through two symmetrically arranged chain stop blocks. Although this kind of structure can fix the anchor chain stably, when the anchor chain is put down and fixed by the chain stop block, if When the anchor chain needs to be released urgently, the anchor chain needs to be lifted again by the windlass to disengage the anchor chain stopper. If the anchor chain cannot be lifted, the anchor chain stopper cannot disengage the anchor chain at this time

Abstract

The invention provides an emergency release method of a chain stopper, which comprises the following specific release steps: (1) a release oil cylinder retracts a piston rod to drive a release pin shaft to move; (2) the release main chain and the release auxiliary chain move along with the release pin shaft, and the distance between the hinge point of the release main chain and the main knife switch and the hinge point of the release auxiliary chain and the auxiliary knife switch changes; (3) the anchor chain descends under the action of gravity; (4) the main switch blade swings along with descending of the anchor chain with the second rotating shaft as a fulcrum; and (5) the anchor chain is separated when the main switch blade swings to a certain angle, so that the anchor chain is separated from the switch blade device.

Description

technical field [0001] The invention relates to the technical field of anchor chain fixing, in particular to an emergency release method for a chain stopper. Background technique [0002] Chain stoppers are used on ships or offshore platforms. The anchor chain stopper is a mechanism that cooperates with the windlass (chain jack) to brake the anchor chain after the anchor chain of the ship is retracted. The existing anchor system All chain stoppers are composed of a chain stopper body and a roller counterweight assembly assembled on the body. The installation of the anchor chain stopper must be adjusted when the anchor chain is to be installed, and the installation and adjustment are more complicated, and only the chain stop function after the windlass breaks down, the entire body occupies a large area, and the operation is not very convenient . [0003] In the patent literature with the Chinese patent application number 201920763626.6 and the announcement date of 2020.01.0...
