Abstract
Description
Technical Field
[0001] This invention relates to the field of marine technology, and in particular to an anchor winch with double locking. Background Technology
[0002] As a key piece of equipment in a ship's anchoring system, the locking reliability of anchor winches directly affects the safety and operational stability of the vessel. They are widely used in anchoring, dropping, and mooring line operations on various types of ships. Currently, most existing marine anchor winches employ a single brake or single locking tooth structure, resulting in a relatively simplistic locking method. Under adverse sea conditions, heavy loads, or sudden shutdowns, this can easily lead to locking failures, slippage, and even safety accidents such as anchor chain slippage and damage to winch components, failing to meet the demands for efficient and safe ship operations. Furthermore, existing anchor winches lack effective buffering structures during braking and locking, easily generating rigid impacts during braking. This not only accelerates wear on winch gears and drive shafts, shortening equipment lifespan, but can also cause sudden changes in cable stress, leading to breakage. In addition, some anchor winches suffer from poor coordination between their drive and locking mechanisms, resulting in delayed locking response. They also have complex structures, are inconvenient to install and maintain, and suffer from high production costs and insufficient adaptability. Although existing technologies have made some improvements to the locking structure of anchor winches, they have not effectively solved the core problems such as insufficient reliability of single locking, lack of buffer protection, and rapid component wear. Therefore, developing an anchor winch with dual locking function, buffer energy absorption effect, and reasonable structure has become an urgent technical problem to be solved in the field of ship deck machinery.

[0031] The oil pipe 541 is a flexible oil pipe.
[0032] The invention is used in the following manner: It has a reasonable and simple structure, low production cost, convenient installation, and complete functions. During operation, the motor 31 in the synchronous drive mechanism 3 starts, and after being reduced in speed by the reduction gearbox 32, it drives the transmission shaft 2 to rotate. Simultaneously, the transmission shaft 2 drives the left small gear 33 and the right small gear 38 to rotate synchronously. The small gear 33 drives the large gear 35 through the connecting gear 34, and the small gear 38 drives the large gear 36 through the connecting gear 37. The two gears synchronously drive the cable drum 6 to rotate, realizing cable winding, cable unwinding, or anchor raising and dropping operations. At this time, the buffer locking mechanism... Both the 4-axis and the dual braking mechanism 5 are in the released state. In the bidirectional locking gear structure 42, the locking end face gear 1 423 and the locking end face gear 2 424 are separated from the locking teeth 422 on the bidirectional gear 421, thus not restricting the rotation of the transmission shaft 2. In the dual braking mechanism 5, the outer brake block 56 is disengaged from the annular body 53, and the inner brake block 546 in the inner brake structure 54 is released from the rotating body 55. When deceleration or pre-locking is required, the inner brake structure 54 of the dual braking mechanism 5 is activated, and oil is supplied to the annular hole 543 through the oil pipe 541 and the connecting pipe 542, pushing the inner oil cylinder 544 to extend, thus activating the inner brake. Block 546 radially hugs the rotating body 55 along the slide groove 545. The rotating body 55 and the cable drum 6 reduce their rotation speed and drive the annular body 53 to rotate accordingly. The pull rope slot 52 on the annular body 53 pulls the pull rope 46 or pull rope 49. The pulling force is transmitted through the guide wheel 45 or guide wheel 411, which pulls the slider 412 or slider 44 to move in the guide groove cavity 43, compressing the buffer spring 47 or buffer spring 410 to achieve buffering and energy absorption. When the machine is completely stopped and locked, after buffering, slider 412 drives the locking end face gear 424, and slider 44 drives the locking end face gear 423 to the middle. The movement engages with the locking teeth 422 on both sides of the bidirectional gear 421, forming the first layer of locking. That is, the bidirectional gear 421 and the transmission shaft 2 are locked by the locking end face gear 1 423 and locking end face gear 2 424, restricting rotation from the power input end. At the same time, the pull rope 1 46 and pull rope 2 49 are tightened and limited, and the annular body 53 and the rotating body 55 are held by the inner brake block 546, thereby realizing the second layer of locking of the cable drum 6, which also achieves double locking. Finally, the outer cylinder 57 extends and pushes the outer brake block 56 to press the outer side of the annular body 53, further enhancing the reliability and safety of long-term locking.
