Description

Technical Field

[0001] The invention relates to a large-scale anchor winch for ships, belonging to the field of anchor winches. Background Art

[0002] The anchor winch is a device installed on the ship, mainly used for the retraction and release of anchor chains or ropes. It is generally equipped with brakes, which provide additional braking force to assist in controlling the slow retraction and release of anchor chains or ropes, especially under heavy load conditions, to ensure the safety of operation. When the ship needs to anchor, the anchor winch lowers the anchor chain or rope to fix the anchor to the bottom of the water, thereby stabilizing the hull; when the ship is ready to set sail, the anchor winch will retract the anchor chain or rope and pull up the anchor so that the ship can continue to sail.

[0003] The Chinese utility model patent with the announcement number CN221214469U discloses a marine safety anchor winch, which relates to the technical field of anchor winches. The utility model includes an anchor winch mechanism, which includes a fixing frame. The utility model realizes that the electric telescopic rod is driven to extend and retract by an external power supply through the thrust of the electric telescopic rod and the positioning frame, the support plate and the airbag and other components, so that the electric telescopic rod squeezes the airbag below it, and the airbag is stressed, and the internal gas is discharged through the one-way valve on the oil outlet pipe, and then the electric telescopic rod is moved away from the airbag. The airbag is tensioned by the internal spring, and then the airbag absorbs the oil inside the oil tank into the airbag through the oil inlet pipe, so that the oil inside the airbag drips onto the anchor chain wrapped on the reel through the oil outlet pipe by squeezing the airbag again, thereby achieving the effect of lubricating and maintaining the anchor chain, preventing it from rusting and breaking, and increasing the service life of the device. However, in the prior art, the oil outlet position is fixed, which affects the uniformity of oiling the anchor chain, thereby affecting the anti-rust effect. Moreover, during the anchoring process, although some water will be discharged due to centrifugal force when the anchor chain is wound on the drum, some water will still remain on the anchor chain. The water will not only accelerate the rusting of the anchor chain, but also, when the oil acts on the anchor chain, the residual water will also affect the adhesion of the oil, thereby affecting the protective effect of the anchor chain.

[0004] Therefore, it is necessary to have a large-scale marine anchor winch to improve the anchor chain protection effect. Summary of the invention

The oil tank 51 is fixedly arranged on the base 1. The oil pump 52 is located above the reel 2. The oil pump 52 is connected to the moving assembly 53. The moving assembly 53 is used to drive the oil pump 52 to reciprocate along the length direction of the reel 2. The outlet end of the oil pump 52 is connected to a nozzle 54. The inlet end of the oil pump 52 is connected to the oil tank 51 through an oil pipe 55. A through hole 56 is provided at one end of the reel 2. The other end of the reel 2 is sealed. A collecting hole 57 is provided on the reel 2. The end of the reel 2 provided with the through hole 56 is inserted into the oil tank 51. The reel 2 is rotatably and sealedly connected to the oil tank 51. A wind force component 58 is disposed in the through hole 56, and the wind force component 58 is connected to the reel 2. The wind force component 58 transports the air in the collection hole 57 to the through hole 56 through the rotation of the reel 2. The wind power assembly 58 includes a connecting shaft 581 and a fan blade 582. The connecting shaft 581 is coaxially arranged with the reel 2, the connecting shaft 581 is fixedly connected to the reel 2, and the fan blade 582 is installed at one end of the connecting shaft 581. The reel 2 comprises a rotating shaft 21 and two baffles 22, the two baffles 22 are coaxially fixedly arranged on the rotating shaft 21 along the length direction of the rotating shaft 21, a gap is arranged between the two baffles 22, the through hole 56 and the collecting hole 57 are both arranged on the rotating shaft 21, the collecting hole 57 is located between the two baffles 22, when the anchor chain is wound, the anchor chain is located between the two baffles 22, and the end of the rotating shaft 21 away from the through hole 56 is connected to the driving mechanism 4; The collecting holes 57 are provided in multiple groups, and the multiple groups of collecting holes 57 are distributed along the length direction of the rotating shaft 21. Each group of collecting holes 57 is provided with multiple collecting holes, and the multiple collecting holes 57 in the same group are evenly distributed in the circumferential direction with the rotating shaft 21 as the center; During the winding of the anchor chain, one end of the anchor chain is fixed on the drum 2, and the other end of the anchor chain is located in the water. The drum 2 is rotated under the support of the support frame 3 by the driving mechanism 4, so that the drum 2 winds the anchor chain. At the same time, the oil pump 52 is started, so that the oil in the oil tank 51 is transported from the oil pipe 55 to the oil pump 52, and the oil in the oil pump 52 is then discharged from the nozzle 54 and acts on the anchor chain wound on the drum 2. In fact, when the anchor chain is wound on the drum 2, the winding position changes back and forth along the winding length direction, thereby improving the uniformity of anchor collection on the drum 2. In addition, the oil pump 52 is moved back and forth along the length direction of the drum 2 by the moving component 53, that is, the position of the nozzle 54 is always opposite to the anchor chain being wound, so that the oil sprayed from the nozzle 54 acts on the anchor chain in time, thereby improving the uniformity of oiling the anchor chain; During the rotation of the rotating shaft 21, the connecting shaft 581 is driven to rotate synchronously. The rotation of the connecting shaft 581 drives the fan blade 582 to rotate, so that the air in the through hole 56 is transported to the oil tank 51, and the air outside the reel 2 passes through the gap between the anchor chains and then is transported to the through hole 56 from the collecting hole 57. Under the action of the airflow, the excess oil on the anchor chain is transported to the oil tank 51 along with the airflow, so that the oil is recycled and reused. Here, through calculation, when the anchor chain rotates, the centrifugal force received by the excess oil on the anchor chain is less than the force of the airflow on the oil, so as to ensure that the excess oil can enter the oil tank 51 along with the airflow. The moving assembly 53 includes a lead screw 531, which is parallel to the reel 2. Both ends of the lead screw 531 are rotatably connected to the two support frames 3 respectively. The lead screw 531 is driven by a first motor 532. A slider 533 is threadedly connected to the lead screw 531. The oil pump 52 is fixedly arranged on the slider 533. During the winding of the anchor chain, the first motor 532 drives the lead screw 531 to reciprocate, so that the slider 533 reciprocates on the lead screw 531. The reciprocating movement of the slider 533 drives the oil pump 52 to reciprocate synchronously. The drying mechanism 6 includes a rotating tube 61, which is perpendicular to the reel 2 and located below the reel 2. A rotating assembly 62 is connected to the rotating tube 61, and a bearing 63 is installed on the rotating tube 61. The outer ring of the bearing 63 is fixedly connected to the oil pump 52. In fact, the outer ring of the bearing 63 is fixedly arranged on the slider 533 through a bracket 64. The moving assembly 53 drives the oil pump 52 to reciprocate while also driving the bearing 63 and the rotating tube 61 to reciprocate synchronously. At the same time, the rotating assembly 62 makes the rotating tube 61 reciprocate on the bearing 63 during the reciprocating movement. The inner circumferential wall of the rotating tube 61 is provided with a water absorbing layer 65, which is a sponge. A sleeve 66 is sleeved on one end of the rotating tube 61, and the sleeve 66 rotates and is sealed with the rotating tube 61. The sleeve 66 is fixedly connected to the oil pump 52. In fact, the sleeve 66 is fixedly arranged on the slider 533 through the bracket 64, that is, the sleeve 66 and the bearing 63 are both connected to the moving component 53. The moving component 53 also drives the sleeve 66 and the bearing 63 to reciprocate synchronously during the process of driving the oil pump 52 to reciprocate. The sleeve 66 is connected to the oil tank 51 through the air pipe 67. During the process of winding the anchor chain, the anchor chain passes through the sleeve 66 and the rotating tube 61 in sequence, and the air in the oil tank 51 is transported from the air pipe 67 to the sleeve 66. A part of the air in the sleeve 66 is discharged from one end of the sleeve 66, and the other part is transported from the other end of the sleeve 66 to the rotating tube 61. Under the action of the airflow, the moisture on the anchor chain is blown away, which is convenient for drying the anchor chain. At the same time, the water on the anchor chain can also be absorbed by the water absorption layer 65, so as to improve the dehydration effect of the anchor chain, that is, to improve the drying efficiency of the anchor chain. In addition, as the rotating tube 61 reciprocates, the water absorbed in the water absorption layer 65 is separated from the water absorption layer 65 under the action of centrifugal force, so as to ensure that the water absorption layer 65 continues to absorb water. The rotating tube 61 is provided with a through groove 68, and the water absorbed in the water absorbing layer 65 passes through the through groove 68 under the action of centrifugal force, thereby facilitating the separation of the water in the water absorbing layer 65; The rotating assembly 62 includes a rack 621 and a rotating gear 622. The rack 621 is parallel to the reel 2. The rack 621 is fixedly arranged on the base 1. The rotating gear 622 is meshed with the rack 621. The rotating gear 622 is installed on the rotating tube 61. During the reciprocating movement of the rotating tube, the rotating gear 622 is driven to reciprocate on the rack 621, so that the rotating gear 622 drives the rotating tube to reciprocate and rotate. By removing the residual moisture on the anchor chain and then applying oil, the protective effect of the anchor chain can be improved; The driving mechanism 4 includes a second motor 41, a driving gear 42, a driven gear 43, a support seat 44, a clutch 45 and a transmission shaft 46. The driven gear 43 is mounted on the end of the reel 2 away from the through hole 56, specifically the end of the rotating shaft 21 away from the through hole 56. The transmission shaft 46 is parallel to the reel 2. The support seat 44 is fixedly arranged on the base 1. The transmission shaft 46 is rotatably connected with the support seat 44. The support seat 44 is used to realize rotation support for the transmission shaft 46. The driving gear 42 is mounted on one end of the transmission shaft 46. The other end of the transmission shaft 46 is connected to the second motor 41 through the clutch 45. The driving gear 42 is meshed with the driven gear 43. When the second motor 41 is started, the transmission shaft 46 is driven to rotate on the support seat 44 through the clutch 45. The rotation of the transmission shaft 46 drives the driving gear 42 to rotate. The rotation of the driving gear 42 drives the driven gear 43 to rotate, thereby realizing the rotation of the reel 2. In summary, by moving the oil pump 52, the nozzle 54 is always facing the anchor chain being wound, that is, the oil sprayed by the nozzle 54 acts on the anchor chain in time, that is, the position of the nozzle 54 is always facing the anchor chain being wound, so as to improve the uniformity of oiling the anchor chain; in addition, the water remaining on the anchor chain is absorbed by the water absorption layer 65, so as to achieve the drying of the anchor chain, and avoid the residual water from affecting the adhesion of the oil, so as to improve the protective effect of the anchor chain; and, by rotating the water absorption layer 65, the water absorbed in the water absorption layer 65 is discharged under the action of centrifugal force, so as to ensure that the water absorption layer 65 continues to absorb water; secondly, the excess oil acting on the anchor chain is transported to the oil tank 51 through the air flow, so as to achieve the recovery and reuse of the oil, and the air transported to the oil tank 51 is transported to the sleeve 66 and acts on the anchor chain, so that the air blows away the residual water on the anchor chain, so as to improve the drying efficiency of the anchor chain; In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
