Description
Technical Field
[0001] This invention relates to the field of ship anchor deployment and take-up technology, specifically to a ship anchor take-up and take-up machine. Background Technology
[0002] An anchor, generally referring to a ship's anchor, is a key component of anchoring equipment. It's an iron vessel used to moor ships, connected to the vessel by an iron chain. By dropping the anchor into the water, the ship can be brought to a stable stop. Its working principle is as follows: when a ship is affected by wind and currents, causing horizontal displacement, the anchor claws will cut into the seabed due to the direction of the force, thus achieving anchoring. When the anchor is raised, the vertical upward pull causes the anchor claws to turn obliquely upward, thereby detaching them from the ground.
[0003] Anchors are to a ship what handbrakes are to a car—an indispensable piece of equipment ensuring ship safety. Currently, most anchoring equipment uses chains to raise and lower the anchor. However, this method has the following problems: When lowering the anchor, the chain constantly rubs against the hull, causing the anti-corrosion coating on the chain's surface to wear down over time, leading to oxidation and rust. This can easily cause the chain to break, posing a danger and causing damage. Furthermore, when retrieving the anchor, it is often secured by a self-locking mechanism between the worm and worm wheel. When this engagement fails, the anchor can easily fall, affecting its normal use and potentially causing danger. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a ship anchor winding machine that has advantages such as increasing the service life of the iron chain and providing self-locking control of the auxiliary worm and worm wheel to ensure the normal use of the ship anchor. It solves the problems of friction reducing the service life of the iron chain and self-locking failure causing the ship anchor to be unusable.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a ship anchor winding machine, comprising a hull and an anchor hole, wherein the anchor hole is formed on the side wall of the hull; The hull is equipped with a chain winding structure, a power structure, a three-stage reduction structure, and an auxiliary protection structure. The anchor hole is located on one side of the chain winding structure, and the middle part of the chain winding structure is opposite to the anchor hole. The chain winding structure is used to wind and unwind the iron chain connecting the anchor. The power structure is located on the other side of the chain winding structure and is used to provide power to the chain winding structure. The three-stage reduction structure is located at one end of the chain winding structure and is used to reduce the output speed of the power structure. The auxiliary protection structure is located between the chain winding structure and the anchor hole and is used to reduce the friction between the iron chain and the hull, while also assisting in fixing the iron chain.
[0006] Preferably, the chain winding structure includes a main support, which is bolted to the hull. Grooves are provided on both sides of the top surface of the main support, and shaft stabilizing blocks are fixedly installed in each groove. Each shaft stabilizing block has a convex shape, and a main shaft is movably mounted on the shaft stabilizing block, passing through it. The main shaft drives the chain winding structure to rotate to wind and unwind the chain. A roller is fixedly mounted on the main shaft for winding and unwinding the chain. Baffles are fixedly mounted at both ends of the roller for limiting the movement of the chain wound on it.
[0007] Preferably, one end of the main shaft is provided with a cable winding drum, which is a frustum-shaped body and is used for winding and unwinding ship cables. The other end of the main shaft is provided with a self-locking device, which includes a self-locking device housing fixedly mounted on the hull, a worm gear rotatably mounted in the self-locking device housing, and a worm fixedly mounted on the main shaft. The worm is located in the self-locking device housing and meshes with the worm gear. When the worm stops rotating, the worm gear cannot drive the worm in the reverse direction, thereby realizing the self-locking of the main shaft.
[0008] Preferably, the power structure includes a motor, which is bolted to the hull and is used to provide power. A shaft connector is fixedly mounted on the shaft of the motor for connection. A primary reduction shaft is fixedly mounted on the shaft connector, and the motor drives the primary reduction shaft to rotate.
[0009] Preferably, the three-stage reduction structure includes a three-stage reduction gearbox, which is bolted to the hull. A cover is bolted to the three-stage reduction gearbox for opening and closing its interior. A second-stage reduction shaft is movably installed inside the three-stage reduction gearbox, penetrating the gearbox. A first-stage reduction gear is fixedly installed on the first-stage reduction shaft, located inside the three-stage reduction gearbox. A second-stage reduction gear is fixedly installed on the second-stage reduction shaft, also located inside the three-stage reduction gearbox, meshing with each other.
[0010] Preferably, the main shaft passes through the three-stage reduction gearbox, a first three-stage reduction gear is fixedly mounted on the third-stage reduction shaft, the first three-stage reduction gear is located inside the three-stage reduction gearbox, a second three-stage reduction gear is fixedly mounted on the main shaft, the second three-stage reduction gear is located inside the three-stage reduction gearbox, the first three-stage reduction gear meshes with the second three-stage reduction gear, and shaft fixing plates are provided at both ends of the second-stage reduction shaft and the third-stage reduction shaft, the shaft fixing plates are used to limit the movement of the second-stage reduction shaft and the third-stage reduction shaft.
[0011] Preferably, the auxiliary protection structure includes an auxiliary support, which is bolted to the hull. An extension rod is fixedly installed on the upper end of one side wall of the auxiliary support, and a rotating disk is movably installed on the upper end of the extension rod. The rotating disk is used to support the iron chain, so that the iron chain forms rolling friction on the rotating disk when it moves. The rotating disk is opposite to the anchor hole, so that the contact between the iron chain and the inside of the anchor hole is reduced when the iron chain passes over the rotating disk and is guided to the anchor hole.
[0012] Preferably, a support block is fixedly installed on the upper end of the other side wall of the auxiliary support. The support block has a groove with a circular structure. A fixing rod is fixedly installed in the groove for fixed support. A limiting rod is movably installed on the fixing rod and is slidably and rotatably fitted onto the fixing rod.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This type of anchor winding machine provides rotational power through a power structure, which then reduces the rotational speed through a three-stage reduction structure. The chain winding structure controls the winding and unwinding of the iron chain on the anchor. At the same time, through an auxiliary protection structure, the sliding friction between the iron chain and the hull is converted into rolling friction between the iron chain and the auxiliary protection structure, thereby reducing friction damage to the iron chain, preventing the iron chain from breaking, and increasing the service life of the iron chain. Meanwhile, the auxiliary protection structure can assist the self-locking device in fixing the iron chain, thereby reducing the locking load of the self-locking device itself and ensuring the normal operation of the device. 2. This type of anchor winding machine, through the setting of the cable winding drum, allows the cable to be wound and unwound simultaneously when the anchor is wound and unwound, which increases the functionality of the device, increases the efficiency of the device, and improves the work efficiency.

[0024] Furthermore, the auxiliary protection structure includes an auxiliary support 24, which is bolted to the hull 1. An extension rod 25 is fixedly installed on the upper end of one side wall of the auxiliary support 24. A rotating disk 26 is movably installed on the upper end of the extension rod 25. The rotating disk 26 is used to support the iron chain, so that the iron chain forms rolling friction on the rotating disk 26 when it moves. The rotating disk 26 is opposite to the anchor hole 2, so that the contact between the iron chain and the inside of the anchor hole 2 is reduced when the iron chain passes over the rotating disk 26 and is guided to the anchor hole 2.
[0025] Furthermore, a support block 27 is fixedly installed on the upper end of the other side wall of the auxiliary bracket 24. The support block 27 has a groove with a circular structure.

The limiting rod 29 can slide or rotate on the fixing rod 28, that is, the limiting rod 29 is slidably and rotatably fitted on the fixing rod 28.
[0026] The limiting rod 29 is used to insert into the chain link of the chain located between the roller and the anchor hole after the chain has been retrieved, thereby providing an additional mechanical safety in addition to the self-locking device 9 to prevent the anchor from falling due to accidental failure of the self-locking device 9.
[0027] Preferably, a support block 27 is fixedly installed on the upper end of the other side wall of the auxiliary bracket 24. The support block 27 has a groove, and a fixing rod 28 is fixedly installed in the groove. A limiting rod 29 is sleeved on the fixing rod 28. The limiting rod 29 can slide along the axial direction of the fixing rod 28 and rotate around its axis. The limiting rod 29 and the fixing rod 28 are damped together so that they can slide or rotate relative to the fixing rod 28 under the action of external force, and maintain their position by friction after the external force is removed. The limiting rod 29 is used to insert into the chain link of the iron chain to help fix the iron chain.
[0028] Working principle of this invention: In use, the motor 12 is started, which drives the shaft connector 13 to rotate. The shaft connector 13 drives the first-stage reduction shaft 14 to rotate, which in turn drives the first-stage reduction gear 16 to rotate. The first-stage reduction gear 16 drives the first-stage reduction gear 17 to rotate, which in turn drives the second-stage reduction shaft 15 to rotate. The second-stage reduction shaft 15 drives the second-stage reduction gear 19 to rotate, which in turn drives the second-stage reduction gear 20 to rotate. The second-stage reduction gear 20 drives the third-stage reduction shaft 18 to rotate, which in turn drives the third-stage reduction gear 21 to rotate. The third-stage reduction gear 21 drives the third-stage reduction gear 22 to rotate, thereby reducing the output speed of the motor 12. Then, the third-stage reduction gear 22 drives the main shaft 5 to rotate, which in turn drives the roller 6 to rotate, thereby winding up or releasing the iron chain fixed on the roller 6, realizing the raising and lowering of the anchor.
[0029] Meanwhile, when the chain is released, it moves from the rotating disk 26 and extends out of the anchor hole 2. The rolling friction between the chain and the rotating disk 26 replaces the sliding friction caused by the chain directly contacting the edge of the hull 1 or the anchor hole 2, thereby reducing the wear of the chain. After the chain is retracted, the chain is initially fixed by the worm gear and worm wheel in the self-locking device 9. Then, the limiting rod 29 is slid or rotated so that the end of the limiting rod 29 extends into the chain to lock the chain, assisting the self-locking device 9 in fixing the chain and ensuring the normal operation of the device.
[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
