Ship hydraulic anchor winch

Abstract

This utility model discloses a hydraulic anchor winch for ships, including a base and a guide assembly. The guide assembly includes a guide tube, a rotating seat is provided in front of the base, a rotating column is provided at the bottom front of the guide tube, a support column is provided at the bottom rear of the guide tube, and a caster wheel is provided at the bottom of the support column. Before anchoring, the guide tube guides the rope. A motor drives a drive gear to rotate, and through gear transmission, the guide tube moves along the outer arc-shaped teeth. When it reaches the outermost edge, the pre-adjusted distance is reached. At this point, the motor reverses, and the guide tube moves to the other side. This reciprocating motion causes the guide tube to swing left and right, achieving uniform guidance of the rope. This ensures the rope is evenly wound around different positions on the hydraulic anchor winch's winding roller, thus avoiding local accumulation, tangling, and knotting of the rope during winding, ensuring smooth anchoring operations.

Description

Technical Field

[0001] This utility model relates to the field of hydraulic anchor lifting technology, specifically to a ship hydraulic anchor lifting machine. Background Technology

[0002] A hydraulic anchor winch is a key piece of equipment powered by a hydraulic system, primarily used on ships, offshore platforms, and other surface or near-shore equipment. Its core function is to use a hydraulic motor to drive a drum to rotate, thereby raising and lowering the anchor chain or cable, thus completing the anchoring and unanchoring operations. Leveraging the high torque, smooth speed regulation, and strong resistance to load impacts inherent in hydraulic transmission, it can adapt to operational needs under various sea conditions. It is also typically equipped with auxiliary devices such as brakes, clutches, and overload protection to ensure operational safety and stable equipment operation, making it an indispensable component of modern ship mooring and berthing systems.

[0003] The existing Chinese patent announcement number CN222179769U, entitled "A Hydraulic Sprocket Anchor Winch for Ships," explicitly states in its abstract that "This utility model discloses a hydraulic sprocket anchor winch for ships, relating to the field of hydraulic anchor winch technology. It includes an anchor winch body composed of a base, support, anchor sprocket, brake, sprocket, gearbox, and electrical control system. A cleaning assembly is provided on the surface of the anchor winch body. The cleaning assembly includes a vertical plate at the top of the anchor winch body, a first fixing plate at the top of the vertical plate, a second fixing plate at the top of the first fixing plate, and a first cleaning block inside the first fixing plate. A first spring is provided at the bottom of the second fixing plate, and a moving plate is connected to the bottom of the first spring. A second cleaning block is provided at the bottom of the moving plate. In this utility model, the cleaning assembly allows for the wiping and drying of seawater or foreign matter on the surface of the anchor chain during winding, preventing residual seawater from corroding the surface and shortening its service life."

[0004] However, in existing technologies, traditional ship hydraulic anchor winches, due to the lack of a dynamic guidance and adjustment mechanism, will naturally form localized concentrated accumulation of ropes during the drum winding process. This accumulation will cause the rope layers to squeeze and bite each other. If anchoring and cable release are required later, the accumulated ropes are prone to jamming between layers and cannot be released smoothly. In some cases, the ropes may even get stuck on the drum or break. This not only seriously affects the timeliness and stability of anchoring operations, but also shortens the service life of the ropes, increases equipment maintenance costs, and poses operational safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic anchor winch for ships to solve the problem mentioned in the background art that the piled-up ropes are difficult to release smoothly due to jamming between layers, and may even cause the ropes to get stuck on the drum or break.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ship's hydraulic anchor winch, including a base and guide components;

[0008] The guiding assembly includes a guide tube, a rotating seat is provided at the front of the base, a rotating column is provided at the bottom front of the guide tube, a support column is provided at the bottom rear of the guide tube, and a caster wheel is provided at the bottom of the support column.

[0009] In a preferred embodiment of this utility model, a hydraulic anchor lifting machine body is provided behind the base.

[0010] In a preferred embodiment of this utility model, the rotating column is rotatably mounted in the rotating seat.

[0011] In a preferred embodiment of this utility model, mounting brackets are provided on the front and rear sides of the guide tube, and guide wheels are rotatably provided on both sides of the mounting brackets.

[0012] In a preferred embodiment of this utility model, an arc-shaped seat is provided behind the rotating seat, and an outer arc-shaped tooth is provided behind the arc-shaped seat.

[0013] In a preferred embodiment of this utility model, a motor is provided in front of the support column, a drive gear is provided on the bottom output end of the motor, the drive gear meshes with an outer arc-shaped tooth, and a PLC controller is provided on one side of the motor.

[0014] In a preferred embodiment of this utility model, an arc-shaped groove is provided at the bottom rear of the arc-shaped seat, and the universal wheel contacts the bottom of the arc-shaped groove.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] Beneficial effects: Before anchoring, the guide tube guides the rope. The rotation of guide wheels on both sides reduces friction between the rope and the guide tube when it enters and exits. The motor drives the drive gear to rotate, and through gear transmission, the guide tube moves along the outer arc teeth. When it moves to the far side, it reaches the pre-adjusted distance. At this point, the motor reverses, and the guide tube moves to the other side. This reciprocating motion causes the guide tube to swing left and right, achieving uniform guidance of the rope. This ensures that the rope is evenly wound around different positions of the hydraulic anchoring machine's winding roller, thus avoiding problems such as local accumulation, tangling, and knotting of the rope during winding, ensuring smooth anchoring operations.

[0017] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please refer to Figures 1-4 This utility model relates to a hydraulic anchor winch for ships, comprising a base 1, which serves as the bottom structure for mounting the overall structure. A hydraulic anchor winch body 11 is located behind the base 1; the hydraulic anchor winch body 11 is the main body of the hydraulic anchor winch and is used for anchoring. Specifically, a YQ30-2 type hydraulic anchor winch can be used. The body is fixed to the base 1 by welding or bolts, a conventional technique used by those skilled in the art. A guide component guides the rope before anchoring, ensuring the rope is evenly wound around different positions on the hydraulic anchor winch's winding rollers. This avoids localized accumulation, tangling, and knotting of the rope during winding, ensuring smooth anchoring operations.

[0026] The guiding assembly includes a guide tube 12, a rotating seat 13 is provided in front of the base 1, and a rotating column 14 is provided at the bottom front of the guide tube 12. The rotating column 14 is locked in the rotating seat 13 and rotates. The guide tube 12 is located directly in front of the hydraulic anchor hoist, that is, the guide tube 12 guides the rope. The front and rear sides of the guide tube 12 are provided with mounting brackets 2, and the mounting brackets 2 are rotatably provided on both sides of the mounting brackets 2. That is, when the rope enters and exits the guide tube 12, it is rotated by the guide wheels 21 on both sides, thereby reducing the friction of the rope and the guide tube 12 when the rope enters and exits the guide tube 12.

[0027] A support column 22 is installed at the bottom rear of the guide tube 12. The support column 22 is used to support the rear of the guide tube 12 and to install other structures. An arc-shaped seat 32 is installed behind the rotating seat 13. An outer arc-shaped tooth 33 is installed behind the arc-shaped seat 32. The outer arc-shaped tooth 33 is coaxial with the rotating column 14. A motor 3 is installed in front of the support column 22. The motor 3 is a servo motor, model SGMAH-08AAA41, and has a built-in electromagnetic brake structure. This brake structure can quickly lock the output shaft when the motor 3 stops running, preventing the guide tube 12 from shifting due to ship swaying or cable tension, thus improving the safety of equipment use. A drive gear 31 is installed on the bottom output end of the motor 3. The drive gear 31 meshes with the outer arc-shaped tooth 33. A PLC controller, model S7-200 SMART CPU, is installed on one side of the motor 3. The SR40 PLC controller is used to control motor 3, which is pre-tested to ensure continuous forward and reverse rotation. Motor 3 drives the drive gear 31 to rotate, and through gear transmission, the guide tube 12 moves along the outer arc-shaped teeth 33. When it reaches the outermost edge, the pre-tested distance is reached, and then motor 3 reverses, causing the guide tube 12 to move to the other side. This reciprocating motion causes the guide tube 12 to swing left and right, achieving uniform guidance of the rope and ensuring that the rope is neatly arranged on the take-up roller. The bottom of the support column 22 is equipped with casters 23, and the bottom of the arc-shaped seat 32 is equipped with an arc-shaped groove 24. The casters 23 contact the bottom of the arc-shaped groove 24, thus supporting the rear of the guide tube 12 and making it more stable during back-and-forth movement. The arc-shaped groove 24 and the outer arc-shaped teeth 33 have the same axis.

[0028] The working principle of this utility model is as follows: Anchoring is carried out by a hydraulic anchor lifting machine. Before anchoring, the guide tube 12 guides the rope and cable. The guide wheels 21 on both sides rotate to reduce the friction between the rope and the guide tube 12 when the rope enters and exits the guide tube 12. The motor 3 drives the drive gear 31 to rotate. Through gear transmission, the guide tube 12 moves along the outer arc tooth 33. When it moves to the sidemost side, it reaches the pre-adjusted distance. At this time, the motor 3 reverses, that is, the guide tube 12 moves to the other side. This reciprocating motion drives the guide tube 12 to swing left and right, so as to achieve uniform guidance of the rope and cable. This allows the rope and cable to be evenly wound around different positions of the hydraulic anchor lifting machine's winding roller, thereby avoiding the problems of local accumulation, tangling and knotting of the rope and cable during the winding process, ensuring the smoothness of the anchoring operation. The universal wheel 23 supports the rear of the guide tube 12, making it more stable when moving back and forth.
