Technical Field
[0001] The invention relates to the technical field of ship equipment, in particular to a retractable anchor bracket. Background Art
[0002] The anchor bracket is a tool used when the anchor is dropped and raised. When the anchor is not working, it mainly plays the role of placing and fixing the anchor. When the anchor is working, it plays the role of limiting the movement path of the anchor when dropping or raising the anchor.
[0003] When sailing or mooring at a port, the hull will shake and cause the anchor to swing, causing bumps against the hull and clinking noises. Existing anchor brackets, whether they are cast or welded products, have the same weakness: all anchor brackets will shake if they are not under the action of the windlass, which will not only bump against the hull but also cause abnormal noises. Although the anchor chain can be locked by a chain stopper in the prior art to prevent the contact between the anchor and the hull, there will be a loose gap in the anchor chain after the windlass is turned off. In this way, the anchor will touch the hull due to the shaking of the hull, causing damage to the hull.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a retractable anchor bracket, which has the following beneficial effects: 1. The retractable anchor bracket drives the driving gear to rotate through the driving source, and the driving gear meshes with the synchronous gear, and then drives the winding roller to rotate through the transmission shaft, and the anchor chain wound on the winding roller is retracted or released. The limit arm controls the rotation speed of the driving gear, so as to accurately control the retraction and release process of the anchor chain. At the same time, the anchor chain is collected in order in the anchor bracket shell through the guide component to ensure smooth operation. The limit component is used to limit the position of the anchor body when it is fully retracted to prevent the anchor body from shaking due to the shaking of the hull, thereby causing damage to the hull, ensuring the smooth retraction and release of the anchor chain, and at the same time ensuring that the anchor body will not continue to move after being collected in place, thereby extending the service life of the equipment and improving safety.
[0016] 2. The retractable anchor bracket passes through the anchor bracket shell through the anchor chain, and the anchor chain contacts the guide pulley on the sliding plate, and the anchor chain is guided by the guide pulley. At the same time, when the winding roller is in the process of the anchor chain, the hydraulic gas support contracts synchronously, thereby driving the sliding plate to slide in the anchor bracket shell, thereby reducing the distance between the anchor chain and the anchor bracket shell, so that one end of the anchor body can enter the anchor bracket shell, thereby completing the fixation of the anchor body, avoiding the gap between the anchor chain and the anchor bracket shell when the collection process stops, which will cause the anchor body and the anchor bracket shell to contact and collide due to the shaking of the hull, thereby effectively improving the service life.
[0017] 3. The retractable anchor bracket, when collecting the anchor chain, the anchor chain enters the anchor bracket housing through the guidance of the guide pulley. When entering the installation box through the anchor chain, the anchor chain preferentially contacts the contact arc plate on one side of the installation plate. The contact arc plate is an arc-shaped structure and is provided with a rubber surface, which can smoothly contact the anchor chain, thereby reducing the friction between the anchor chain and the guide component, protecting the anchor chain, and improving the durability of the overall system. The multiple groups of contact grooves on the contact arc plate further help the precise positioning and guiding of the anchor chain, ensuring the smooth operation of the anchor chain during the retraction and release process, thereby realizing the precise guidance of the anchor chain, avoiding the chain from being offset or stuck during the retraction and release process, improving the smoothness of the operation, and making the overall device more efficient and reliable.
[0018] 4. When the retractable anchor bracket contacts multiple groups of contact plates on the contact frame through the anchor chain, it can drive the flip plate to flip, thereby driving the synchronization rod to rotate. When the synchronization rod rotates, the deflection block can rotate synchronously. When the deflection block rotates, it can contact the through slot and control its rotation. When the anchor chain stops being retracted, the limit plate can contact the anchor body, and the anchor body can be accurately positioned by the limit plate to ensure that the anchor body is in the correct position, and fixed support for the anchor body is achieved, thereby ensuring the stability of the anchor body after collection is completed, reducing equipment wear, and at the same time extending the service life of the entire anchor bracket system, thereby enhancing the overall reliability and operation efficiency of the device.
[0019] 5. The retractable anchor bracket moves to one side along the axis of the mounting plate driven by the anchor chain through the mounting plate, that is, during the winding process of the anchor chain, the pushing rod is driven to move synchronously. When the pushing rod is moving, it can drive the limit block to move to one side synchronously. When the limit block moves, it can push the driving plate to move to one side, thereby rotating the driving gear ring engaged with it, and then realizing the rotation of the rotating rod. When the rotating rod rotates, it can synchronously drive the synchronous teeth to move through the driving gear ring, and then the synchronous teeth drive the lifting plate to rise and fall, so that the lifting plate contacts the bottom of the contact frame, thereby assisting the limit assembly to achieve the fixing effect of the anchor chain, further improving the working efficiency and reliability of the device, and ensuring the operational safety of the anchor.

At the same time, the anchor chain 11 is collected in an orderly manner in the anchor bracket housing 10 through the guide assembly to ensure smooth operation. The limit assembly is used to limit the position of the anchor body 12 when it is fully retracted to prevent the anchor body 12 from shaking due to the shaking of the hull, thereby causing damage to the hull, ensuring the smooth retraction and release of the anchor chain 11, and at the same time ensuring that the anchor body 12 will not continue to move after being collected in place, thereby extending the service life of the equipment and improving safety.

The contact arc plate 26 is an arc-shaped structure and is provided with a rubber surface, which can smoothly contact the anchor chain 11, thereby reducing the friction between the anchor chain 11 and the guide component, protecting the anchor chain 11, and improving the durability of the overall system. The multiple groups of contact grooves 27 on the contact arc plate 26 further help the precise positioning and guiding of the anchor chain, ensuring the smooth operation of the anchor chain 11 during the retraction and release process, thereby achieving precise guidance of the anchor chain 11, avoiding the chain from offsetting or jamming during the retraction and release process, improving the smoothness of operation, and making the overall device more efficient and reliable.
