Description

Technical Field

[0001] This utility model relates to the field of hydraulic winches, and in particular to a marine anchor-raising hydraulic winch. Background Technology

[0002] Marine anchor winches are key equipment on ship decks, primarily used for anchoring, mooring, towing, and cargo hoisting. Their core function is to smoothly lift and haul heavy loads via a hydraulic system. Structurally, they use a hydraulic motor as the core power unit, employing either a low-speed, high-torque motor or a high-speed motor with a reducer to directly drive the drum's rotation. A normally closed hydraulic brake ensures automatic locking in case of power failure, preventing the load from slipping. A planetary gearbox is integrated inside the drum, optimizing space layout and improving transmission efficiency. The drum surface undergoes special treatment to enhance the wear resistance and anti-slip properties of the wire rope winding. Technically, their rated load ranges from 10 tons to 5000 tons, supporting high-intensity operational needs. The hydraulic system achieves stepless speed regulation via proportional valves, allowing precise control of anchoring / hauling speeds, with a minimum stable speed of 0.1 rpm. The hydraulic circuit integrates a balance valve and overload protection device, eliminating secondary slippage and hook vibration issues, thus improving operational safety. In terms of performance advantages, hydraulic drive provides constant torque output, avoiding the power attenuation caused by voltage fluctuations in electric winches, making it particularly suitable for the complex electrical environments of ocean-going vessels. Its low-speed stability is superior to mechanically driven winches, allowing for precise control of vessel displacement during mooring operations. The compact modular design reduces the overall size by 30% compared to electric winches of the same specifications, facilitating deck layout optimization.

[0003] During operation, marine hydraulic winches often encounter a problem: when the winch drives the chain, marine debris, including seaweed, shell fragments, and small marine organisms, often adheres to the chain. Additionally, due to the marine environment, the chain inevitably becomes contaminated with seawater. The salt and other chemicals in seawater are highly corrosive to metals. Prolonged exposure of the chain, contaminated with debris and seawater, to the winch will cause corrosion on its surface. This not only affects the chain's appearance but, more importantly, reduces its strength and durability, increasing the risk of breakage. Corrosion can also extend to other metal components of the winch, such as the winch disc and bearings, ultimately affecting the normal operation and safety of the entire hydraulic winch system.

The cleaning operation of the anchor head chain 8 is realized through the cleaning brush 13, ensuring that the chain remains clean during use and prolonging its service life.

[0015] The support frame 2 is firmly mounted on the mounting base 1 by bolts, and the winch drum 3 is directly opposite the opening on the end face of the mounting base 1, which allows the anchor head chain 8 to pass through and realizes a drainage function, preventing water accumulation from affecting the normal operation of the winch. The winch drum 3 is mounted on the support frame 2 through a rotating shaft and a bearing system, ensuring smooth operation and reducing friction and wear. The number of the fixing seats 5 is consistent with the number of the winch drums 3, the fixing sleeve 6 and the fixing seat 5 are connected by bolts, and the fixing seat 5 and the mounting base 1 are also mounted on the hull by bolts, ensuring the stability of the entire device. The cross section of the fixing sleeve 6 is designed in a "Y" shape, the fixing chain 4 passes through the cavity between the fixing sleeve 6 and the fixing seat 5, and the fixing inserted rod 7 is inserted into the side wall of the fixing sleeve 6 and passes through the opening on the fixing chain 4, further strengthening the fixing effect of the chain.

[0016] The fixed chain 4 and the anchor head chain 8 jointly form a complete winch chain, and the tail of the anchor head chain 8 is connected with an anchor for anchor raising and anchor lowering operations. Both the fixed chain 4 and the anchor head chain 8 are designed in an "∞" shape to enhance the use efficiency and flexibility, making the storage and release process smoother. The connecting plate 9 and the bending piece 10 are fixed together by welding, and the bending piece 10 is made of bendable metal material, which increases the flexibility and adaptability of the connecting plate 9.

As the anchor chain 8 passes through the mounting base 1 under the guidance of the winch 3, the cleaning brush 13 automatically cleans the chain, removing attached dirt and moisture. After the anchor is lifted, the winch 3 continues to rotate, neatly storing the anchor chain 8 and the fixed chain 4 to prevent the chain from becoming loose.

[0021] Start the marine anchor-lifting hydraulic winch to prepare for cleaning operations. Ensure the anchor chain 8 passes through the opening in the mounting base 1. Rotate the winch 3 to bring the anchor chain 8 into contact with the cleaning brush 13. The roller 12 drives the cleaning brush 13 to rotate, cleaning the anchor chain 8 and removing dirt and moisture. After cleaning, continue operating the winch to neatly store the anchor chain 8 and the fixing chain 4. Regularly check the wear of the cleaning brush 13 and replace it as needed to ensure effective cleaning. These steps ensure the normal operation of the marine anchor-lifting hydraulic winch and the cleaning and maintenance of the chain.
