An integrated hydraulic anchor winch

Abstract

This utility model relates to the field of marine component technology and discloses an integrated hydraulic anchor winch, including a base, a gearbox fixed on the base, an input shaft of the gearbox connected to an external power source, a reel connected to the output shaft of the gearbox, the reel being rotatably mounted on the base, a buffer device installed on the base, a rope wound around the reel, and the output end of the rope wound around the buffer device and extending away from the reel.

Description

Technical Field

[0001] This utility model relates to the field of ship parts technology, and more specifically, it relates to an integrated hydraulic anchor winch. Background Technology

[0002] In ship operations, anchor winches are crucial equipment for ensuring the safe berthing of vessels. The tension on the anchor chain acts directly on the winch spool. As the ship rocks constantly in the wind and waves at sea, the tension on the anchor chain changes continuously, making the spool highly susceptible to damage from excessive instantaneous torque. Frequent torque impacts accelerate the wear and tear on critical components of the equipment.

[0003] Currently, common anchor winches lack effective structures to mitigate the impact of wind and waves on the anchor chain, which shortens the overall service life of the anchor winch and increases ship maintenance costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated hydraulic anchor winch with a longer service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An integrated hydraulic anchor winch includes a base, a gearbox fixed on the base, an input shaft of the gearbox connected to an external power source, a reel connected to the output shaft of the gearbox, the reel being rotatably mounted on the base, a buffer device installed on the base, a rope wound around the reel, and the output end of the rope being wound around the buffer device and extending away from the reel.

[0007] The present invention is further configured such that: the buffer device includes two supports, the two supports are fixed on the base, an mounting cylinder is fixed on the support, a crossbar is rotatably connected to the two mounting cylinders, the rope is wound around the crossbar, and a buffer element is provided on the crossbar, the buffer element can be engaged with the mounting cylinder.

[0008] The present invention is further configured such that: the mounting cylinder has a cylindrical structure, the bottom of the mounting cylinder is fixed on a corresponding bracket, an inner ratchet is provided on the inner side of the mounting cylinder, the direction of rotation of the crossbar is positive when the rope is unwound, the direction of the ratchet teeth of the inner ratchet is opposite to the positive direction, the two ends of the crossbar are provided with end heads, the end heads are rotatably mounted on the inner wall of the mounting cylinder, the buffer is mounted on the end heads, and the buffer can be engaged with the inner ratchet.

[0009] The present invention is further configured such that: the buffer component includes a connecting post, the connecting post is fixed to the end, a spring is connected to the connecting post, and a pawl is connected to the free end of the spring, the pawl being able to engage with the inner ratchet.

[0010] The present invention is further configured such that: a sliding groove is provided on the end, the sliding groove extends in an inclined direction, and a sliding post is provided on the pawl, the sliding post being slidably connected to the sliding groove.

[0011] The advantages of this utility model are:

[0012] Equipped with a buffer device, the rope extends from the reel and first wraps around the crossbar of the buffer device before extending outward. Buffer components are installed at both ends of the crossbar, which are rotatably mounted on the mounting cylinder. During normal operation, the rope moves at a constant speed, synchronously driving the crossbar to rotate at a constant speed. When the tension on the rope changes suddenly due to wind and waves, it will cause the rope to accelerate. The pawl overcomes the spring tension under inertia and engages with the inner ratchet, thus forming a buffer and preventing the tension from acting directly on the reel, extending the service life of the anchor winch.

[0023] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0024] Please see Figure 1-7 The present invention provides the following technical solution:

[0025] An integrated hydraulic anchor winch includes a base 1, a gearbox 2 fixed on the base 1, an input shaft of the gearbox 2 connected to an external power source, a reel 3 connected to the output shaft of the gearbox 2, the reel 3 being rotatably mounted on the base 1, a buffer device 5 installed on the base 1, a rope 4 wound around the reel 3, the output end of the rope 4 being wound around the buffer device 5 and extending away from the reel 3 for output.

[0026] The buffer device 5 includes two supports 51, which are fixed on the base 1. A mounting cylinder 52 is fixed on the support 51. A crossbar 53 is rotatably connected to the two mounting cylinders 52. A rope 4 is wound around the crossbar 53. A buffer element 54 is provided on the crossbar 53. The buffer element 54 can be engaged with the mounting cylinder 52.

[0027] The mounting cylinder 52 has a cylindrical structure. The bottom of the mounting cylinder 52 is fixed on the corresponding bracket 51. An inner ratchet 521 is provided on the inner side of the mounting cylinder 52. When the rope 4 is unwound, the rotation direction of the crossbar 53 is positive. The direction of the ratchet teeth of the inner ratchet 521 is opposite to the positive direction. The two ends of the crossbar 53 are provided with end heads 531. The end heads 531 are rotatably installed on the inner wall of the mounting cylinder 52. The buffer 54 is installed on the end heads 531. The buffer 54 can be engaged with the inner ratchet 521.

[0028] The buffer 54 includes a connecting post 541, which is fixed on the end 531. A spring 542 is connected to the connecting post 541, and a pawl 543 is connected to the free end of the spring 542. The pawl 543 can engage with the inner ratchet 521.

[0029] When the anchor winch is running normally, the spring 542 is stretched to a certain degree, and the pawl 543 is not engaged with the inner ratchet 521. When the end of the rope 4 is pulled by wind and waves, it will suddenly drive the crossbar 53 to accelerate and rotate in the positive direction. At this time, the pawl 543 will overcome the tension of the spring 542 under the action of inertia and extend outward and engage with the inner ratchet 521 to lock, thereby avoiding the tension from acting directly on the reel 3.

[0030] A groove 532 is provided on the end 531. The groove 532 extends in an inclined direction. A sliding post 544 is provided on the pawl 543. The sliding post 544 is slidably connected to the groove 532. The movement direction of the pawl 543 can be planned through the groove 532 to ensure that the pawl 543 can be engaged with the inner ratchet 521.

[0031] Specifically, a buffer device 5 is provided. The rope 4 extends from the reel 3 and first wraps around the crossbar 53 of the buffer device 5, and then extends outward. Buffer components 54 are provided at both ends of the crossbar 53. The two ends of the crossbar 53 are rotatably mounted on the mounting cylinder 52. During normal operation, the rope 4, which moves at a uniform speed, synchronously drives the crossbar 53 to rotate at a uniform speed. When the tension on the rope 4 changes suddenly under the action of wind and waves, it will drive the rope 4 to move faster. The pawl 543 overcomes the tension of the spring 542 under the action of inertia and engages with the inner ratchet 521, thereby forming a buffer and preventing the tension from acting directly on the reel 3, thus extending the service life of the anchor winch.
