AI Technical Summary
After prolonged use, existing mechanical chain catchers cause anchor chain deformation, resulting in unsuitable guillotine positions and difficulty in effectively securing the anchor chain. Furthermore, manual operation is cumbersome and cannot meet the needs of large vessels.
It adopts a manually adjustable hydraulic chain stopper, which achieves automatic adjustment and fixation of the chain stopper through the combination design of hydraulic cylinder and chain stopper. Combined with detachable adjustment pad and fixed baffle, it ensures that the position of the chain stopper adapts to the deformation of the anchor chain. The hydraulic pump is easy and efficient to operate.
It enables automatic adjustment of the gate position after the anchor chain deforms, improving the reliability of fixing and the convenience of operation, and is suitable for the safety requirements of large ships.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of marine vessel design and construction, and specifically relates to a marine manual hydraulic adjustable chain catcher. Background Technology
[0002] A marine chain catcher is an auxiliary device for anchor pulling located in front of the anchor chain spool at the bow of a ship. After the anchor chain emerges from the spool, it passes through the chain catcher into the chain canister, lowering the anchor and connecting chain into the sea to secure the ship's position. The retrieval of the anchor and chain is the reverse operation. The chain catcher guides the lowering and retrieval of the anchor chain. Once the anchor chain is retrieved, its own guillotine secures and locks the chain, bearing the tension of the anchor chain and its own weight at the end of the chain.
[0003] As an emerging auxiliary equipment for anchoring in recent years, new adjustable chain catchers and manual hydraulic chain catchers have emerged based on the original mechanical chain catcher, as well as the new combined adjustable manual hydraulic chain catcher type mentioned in this invention that simultaneously possesses the above two types. Summary of the Invention
[0004] To solve the above problems, the present invention provides a marine manually operated hydraulic adjustable chain stop, the technical solution of which is as follows:
[0005] A marine manual hydraulic adjustable chain stopper is disclosed, comprising a guide roller fixed to the chain stopper body via a main shaft, a 150mm raised base at the bottom of the chain stopper body, a brake blade on one side of the guide roller, fixed baffles on both sides of the brake blade, the fixed baffles being fixed to the chain stopper body, a vertically mounted hydraulic cylinder fixed below the brake blade and on the chain stopper body, the top of the hydraulic rod of the hydraulic cylinder being connected to one end of the brake blade, the surface of the brake blade having a groove; an adjusting shim is provided between the fixed baffles and the brake blade, the adjusting shim being fixed by a detachable shaft pin.
[0006] The front end of the chain stopper body is fixed with a chain anchor fixing shaft. The chain anchor passes around the chain anchor fixing shaft and the anchor chain passes around the guide roller. When the anchor chain is locked by the guillotine, it passes through the anchor chain ring and tightens the chain anchor.
[0007] Furthermore, the aforementioned marine manual hydraulic adjustable chain catcher has an anchor chain cylinder located diagonally below the main body of the chain catcher. One end of the anchor chain passes around the guide roller and enters the anchor chain cylinder, then passes through the anchor chain cylinder and enters the seabed for fixation; the other end of the anchor chain is wrapped around the anchor winch.
[0008] Furthermore, in the aforementioned marine manual hydraulic adjustable chain catcher, the hydraulic cylinder is connected to the hydraulic pump via a hydraulic pipeline. The top of the hydraulic pump has an operating lever. After pressing the operating lever, the hydraulic lever lifts the gate blade and secures the anchor chain.
[0009] Furthermore, the aforementioned marine manual hydraulic adjustable chain stop has a maximum opening angle of 65°.
[0010] Furthermore, the aforementioned marine manual hydraulic adjustable chain catcher is equipped with a pressure gauge at the connection between the operating lever and the hydraulic pipe.
[0011] Furthermore, the aforementioned marine manual hydraulic adjustable chain stop has an adjustment margin of 30mm on both sides of the guillotine.
[0012] Furthermore, the aforementioned marine manual hydraulic adjustable chain puller has an anchor chain storage compartment located below the anchor winch, from which the anchor winch pulls the anchor chain.
[0013] When using this invention, the combined manual hydraulic adjustable chain stopper is easy to install, safe and reliable to use, and meets the relevant specifications.
[0014] The adjustable chain stopper has a number of adjustable baffles at the front and rear positions of the fixed blade. The baffles can be adjusted in front of and behind the blade, thereby adjusting the position of the fixed blade. This solves the problem that when the anchor chain is deformed after a period of use, the original blade position is no longer suitable and the blade cannot lock the anchor chain.
[0015] This system replaces the original, cumbersome anchor chain-mounted gate, which was manually opened and closed by manpower, by raising and lowering the hydraulic pump and cylinder. This hydraulic system is popular with foreign shipowners, especially in large vessels such as container ships. Attached Figure Description

Detailed Implementation
[0021] The invention will be further described with reference to the accompanying drawings.
[0022] like Figure 1 , 2 As shown, a marine manually adjustable hydraulic chain catcher includes a guide roller fixed to the chain catcher body via a main shaft. The chain catcher body has a 150mm raised base at its bottom. A brake blade is installed on one side of the guide roller, and fixed baffles are installed on both sides of the brake blade. The fixed baffles are fixed to the chain catcher body. A vertically mounted hydraulic cylinder is fixed below the brake blade and on the chain catcher body. The top of the hydraulic rod of the hydraulic cylinder is connected to one end of the brake blade. The hydraulic cylinder is connected to a hydraulic pump via hydraulic lines (e.g., ...). Figure 3 As shown), the hydraulic pump has an operating lever on top, and a pressure gauge is installed at the connection between the operating lever and the hydraulic pipeline. After pressing the operating lever, the hydraulic rod lifts the gate. The gate has a groove on its surface, and the anchor chain ring is vertically fixed in the groove. The maximum opening angle of the gate is 65°.
[0023] An adjusting shim is provided between the fixed baffle and the switch. The adjusting shim is fixed by a detachable shaft pin. The adjustment allowance on both sides of the switch is 30mm.
[0024] The front end of the chain stopper body is fixed with a chain anchor fixing shaft. The chain anchor passes around the chain anchor fixing shaft and the anchor chain passes around the guide roller. When the anchor chain is locked by the guillotine, it passes through the anchor chain ring and tightens the chain anchor.
[0025] like Figure 4 As shown, an anchor chain canister is located diagonally below the main body of the chain catcher. One end of the anchor chain passes over a guide roller, enters the anchor chain canister, and then passes through the canister to the seabed for fixation. The other end of the anchor chain is wound around the anchor winch. An anchor chain storage compartment is located below the anchor winch, and the anchor winch pulls the anchor chain from the storage compartment.
