Description

Technical Field

[0001] This invention relates to the field of ship anchor chain winches, specifically to a ship anchor chain winch. Background Technology

[0002] Anchor chains are specialized chains that connect anchors to the hull and transmit anchor holding force. They typically consist of anchor end links, intermediate links, and end links. Based on the structure of the chain links, they can be divided into two types: studded anchor chains and studless anchor chains. The former is stronger than the latter. Based on the manufacturing method, anchor chains can be divided into cast steel anchor chains and welded anchor chains. The length of an anchor chain is measured in sections, with each section having a standard length of 27.5 meters. Sections are connected by connecting links or shackles. Typically, the main anchor on each side of a 10,000-ton ship has about 12 sections of chain. Anchor chain winches are machines used on ships to raise and lower anchors and anchor chains. They can be driven by various power sources such as human power, steam engines, electric motors, and hydraulic motors.

[0003] Anchor chain winches are typically installed on the deck at the stern of a ship for easy operation and control. They are used in conjunction with an anchor winch and a jack to facilitate operations such as raising and dropping anchors and mooring lines. However, when the anchor chain winch winds up the anchor chain, it is easy for the chain to become tangled and piled up. Excessive pile-up can cause jamming and affect the operation of the anchor chain winch. In addition, the space at the stern is relatively small, which can easily obstruct the position and make it inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a ship anchor chain winch to solve the problems mentioned in the background art, such as the easy entanglement and stacking of anchor chains when the anchor chain is wound up, excessive stacking causing jamming and affecting the operation of the anchor chain winch, and the small space at the stern of the ship easily causing positional obstruction and inconvenience in use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ship anchor chain winch, comprising: A lifting base is used to provide auxiliary support for lifting the device. A winch mechanism is located on the top side of the lifting base. The winch mechanism includes a fixed bracket, and a winch roller is rotatably arranged between the two fixed brackets. An anchor chain body is movably wound around the outside of the winch roller. A connecting shaft is provided at one end of the winch roller, and a drive gear is provided on the outside of the connecting shaft. Four reduction gears are meshed with the outer periphery of the drive gear. An auxiliary winding mechanism is located on the other side of the top of the lifting base. The auxiliary winding mechanism includes a fixed bottom shell, an anchor chain sleeve is provided above the fixed bottom shell, connecting brackets are symmetrically provided on one outer wall of the fixed bottom shell, a rotating support shaft is provided between the connecting brackets, and an auxiliary roller adapted to the anchor chain body is rotatably provided on the outside of the rotating support shaft. A lifting mechanism is located at the bottom of the lifting base. The lifting mechanism includes a fixed base plate. Lifting cylinders are provided at the four corners of the top of the fixed base plate. Screw locking holes are symmetrically provided on the side wall of the lifting base. A second screw is rotatably provided on the inner wall of the screw locking hole. One end of the second screw is connected and fixed to the drive end of a second servo motor. Telescopic brackets are symmetrically provided at the bottom of the fixed base. A limit slide is provided at one end of the telescopic bracket. A limit slide hole adapted to the limit slide is provided on the top of the lifting base. A telescopic locking hole adapted to the telescopic bracket is provided on one side of the lifting base.

[0006] Preferably, one side of the fixed bracket is provided with an AC motor, the drive end of the AC motor is connected and fixed to the other end of the winch roller, and the other side of the fixed bracket is provided with a protective shell, the inner wall of the protective shell is rotatably provided with a connecting shaft adapted to the reduction gear.

[0007] Preferably, the fixed base shell is provided with a mounting hole, the inner wall of the mounting hole is rotatably provided with a first lead screw, and a first servo motor is provided on one side of the fixed base shell, the drive end of the first servo motor is connected and fixed to one end of the first lead screw.

[0008] Preferably, a lead screw nut is slidably provided on the outside of the first lead screw, and a movable slider is provided on the top of the lead screw nut. The movable slider is adapted to a movable sliding hole, which is located on the top of the fixed base.

[0009] Preferably, a limiting baffle is provided on one side of the top of the fixed bracket, and the limiting baffle is provided with a rotating locking hole adapted to the winch roller.

[0010] Preferably, the top of the movable slider is provided with a connecting base plate, the top of the connecting base plate is symmetrically provided with clamping support plates, and the inner wall of the clamping support plates is provided with a rotating shaft.

[0011] Preferably, the anchor chain sleeve is provided with fixed support blocks symmetrically arranged on both sides, and the fixed support blocks are provided with rotation grooves adapted to the rotation shaft.

[0012] Preferably, the protective shell is connected and fixed to the fixing bracket by a first bolt.

[0013] Preferably, the connecting base plate is connected and fixed to the movable slider by a second bolt.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The limiting baffle of this invention facilitates the limiting of the hoisting of the anchor chain body, preventing the anchor chain body from falling off the hoisting roller and reducing the situation of the anchor chain body getting tangled. The AC motor drives the hoisting roller to rotate, which facilitates the hoisting operation of the anchor chain body. While the AC motor drives the hoisting roller, the speed needs to be slowed down, which helps the auxiliary winding mechanism to perform auxiliary winding. The drive gear is fixed to the hoisting roller by the connecting clip shaft. The rotation of the hoisting roller drives the drive gear to rotate. The drive gear meshes with the reduction gear, which helps to improve the stability of the hoisting roller's uniform rotation. One end of the anchor chain body passes through the anchor chain sleeve, which facilitates the limiting and fixing of the anchor chain body. The moving slider drives the anchor chain sleeve to reciprocate, which facilitates the uniform winding of the auxiliary winch roller. As the anchor chain sleeve moves, it drives the anchor chain body to wind layer by layer, which helps to reduce the winding and overlapping of the anchor chain body and improves the stability of the winch. The rotation of the auxiliary roller facilitates the sliding of the anchor chain body, which can reduce the obstruction of the anchor chain sleeve on the winch limiting of the anchor chain body, improve the smoothness of the winch, and make it convenient and fast. The fixed base plate is easily fixed to the stern deck with fastening bolts. The stern deck space is small, and when not in use, the fixed base shell remains in a retracted state to save installation space. When the anchor chain needs to be winched, the lifting cylinder drives the lifting base to rise, and the second screw rotates to extend the fixed base shell outward for winching, which reduces obstruction to other equipment.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figures 1-8As shown, this application provides a ship anchor chain winch, including a lifting base 1 for providing auxiliary support for lifting the device. A winch mechanism 2 is located on the top side of the lifting base 1. The winch mechanism 2 includes fixed supports 201, with a winch roller 204 rotatably arranged between the two fixed supports 201. Anchor chain body 3 is movably wound around the outside of the winch roller 204. A connecting shaft 206 is provided at one end of the winch roller 204, and a drive gear 207 is provided outside the connecting shaft 206. Four reduction gears 208 are meshed with the outer periphery of the drive gear 207. An AC motor 205 is provided on one side of the frame 201. The drive end of the AC motor 205 is connected and fixed to the other end of the winch roller 204. A protective shell 209 is provided on one side of another fixed bracket 201. A connecting shaft 210 adapted to the reduction gear 208 is rotatably provided on the inner wall of the protective shell 209. A limit baffle 202 is provided on the top side of the fixed bracket 201. A rotation hole 203 adapted to the winch roller 204 is provided on the limit baffle 202. The protective shell 209 is connected and fixed to the fixed bracket 201 by a first bolt 211.

[0021] In this embodiment: the fixed bracket 201 facilitates the support of the winch roller 204, and the limiting baffle 202 facilitates the limiting of the winch of the anchor chain body 3, preventing the anchor chain body 3 from coming off the winch roller 204 and reducing the possibility of the anchor chain body 3 getting tangled. The AC motor 205 drives the winch roller 204 to rotate, facilitating the winch operation of the anchor chain body 3. While the AC motor 205 drives the winch roller 204, the speed needs to be slowed down to help the auxiliary winding mechanism 4 to perform auxiliary winding. The connecting clip 206 fixes the drive gear 207 to the winch roller 204. The rotation of the winch roller 204 drives the drive gear 207 to rotate, thus facilitating the winding operation. Gear 207 meshes with reduction gear 208, which facilitates the improvement of the stability of the winch roller 204 rotating at a constant speed. The protective housing 209 can easily drive the reduction gear 208 to rotate through the connecting shaft 210. The protective housing 209 can protect the drive gear 207 and reduction gear 208, preventing dust from entering and reducing the impact on the smoothness of the rotation of the drive gear 207 and reduction gear 208. Lubricating oil needs to be applied between the drive gear 207 and reduction gear 208 to ensure better smoothness. The protective housing 209 can be easily and flexibly disassembled and assembled through the first bolt 211, and it is convenient to add lubricating oil at regular intervals, which is convenient and quick.

[0022] Specifically, such as Figures 1-8As shown, the auxiliary winding mechanism 4 is located on the other side of the top of the lifting base 1. The auxiliary winding mechanism 4 includes a fixed base shell 401, an anchor chain sleeve 412 is provided above the fixed base shell 401, connecting brackets 415 are symmetrically arranged on one outer wall of the fixed base shell 401, a rotating support shaft 416 is arranged between the connecting brackets 415, an auxiliary roller 417 adapted to the anchor chain body 3 is rotatably arranged outside the rotating support shaft 416, an installation hole 402 is provided on the fixed base shell 401, a first lead screw 403 is rotatably arranged on the inner wall of the installation hole 402, a first servo motor 404 is provided on one side of the fixed base shell 401, and the drive end of the first servo motor 404 is connected to one end of the first lead screw 403. The first lead screw 403 is fixed, and a lead screw nut 405 is slidably provided on its outside. A movable slider 406 is provided on the top of the lead screw nut 405. The movable slider 406 is adapted to the movable sliding hole 407, which is located on the top of the fixed base shell 401. A connecting base plate 408 is provided on the top of the movable slider 406. A clamping support plate 410 is symmetrically provided on the top of the connecting base plate 408. A rotating shaft 411 is provided on the inner wall of the clamping support plate 410. Fixed support blocks 413 are symmetrically provided on both sides of the anchor chain sleeve 412. A rotating groove 414 adapted to the rotating shaft 411 is opened on the fixed support block 413. The connecting base plate 408 is connected and fixed to the movable slider 406 by a second bolt 409.

[0023] In this embodiment: the auxiliary winding mechanism 4 facilitates the limiting control of the winding of the anchor chain body 3, preventing excessive winding speed from causing uneven stacking of the anchor chain bodies 3 and resulting in entanglement, which in turn affects the winching effect of the ship's anchor chain winch. The anchor chain body 3 is unwound by passing one end through the anchor chain sleeve 412. The anchor chain sleeve 412 facilitates the limiting and fixing of the anchor chain body 3. The anchor chain sleeve 412 is movably fixed to the rotating shaft 411 on the clamping support plate 410 via a fixed support block 413 and a rotating groove 414, facilitating the adjustment of the angle of the anchor chain sleeve 412 as the anchor chain body 3 is wound. The clamping support plate 410 is connected and fixed to the movable slider 406 via a connecting base plate 408 and a second bolt 409. The bottom opening of the fixed base shell 401 facilitates the installation of the first lead screw 403 and the lead screw nut 405. The lead screw nut 405 is fixed to the movable slider 406 via a first servo motor. The machine 404 drives the first lead screw 403 to rotate. The rotation of the first lead screw 403 drives the lead screw nut 405 to move linearly, which in turn drives the moving slider 406 to reciprocate inside the moving sliding hole 407. The moving slider 406 drives the anchor chain sleeve 412 to reciprocate, which facilitates the uniform winding of the auxiliary winch roller 204. As the anchor chain sleeve 412 moves, it drives the anchor chain body 3 to wind layer by layer, which helps to reduce the winding and overlapping of the anchor chain body 3 and improves the stability of the winch. The connecting bracket 415 fixes the rotating support shaft 416 on one side of the fixed base shell 401. The rotating support shaft 416 drives the auxiliary roller 417 to rotate. The auxiliary roller 417 is placed below the anchor chain body 3 and in contact with the anchor chain body 3. The rotation of the auxiliary roller 417 facilitates the sliding of the anchor chain body 3, which can reduce the obstruction of the anchor chain sleeve 412 to the winch limit of the anchor chain body 3 and improve the smoothness of the winch.

[0024] Specifically, such as Figures 1-8 As shown, the lifting mechanism 5 is located at the bottom of the lifting base 1. The lifting mechanism 5 includes a fixed base plate 501. Lifting cylinders 502 are provided at the four corners of the top of the fixed base plate 501. Screw locking holes 509 are symmetrically provided on the side wall of the lifting base 1. A second screw 503 is rotatably provided on the inner wall of the screw locking hole 509. One end of the second screw 503 is connected and fixed to the drive end of the second servo motor 504. Telescopic brackets 505 are symmetrically provided at the bottom of the fixed base shell 401. A limiting slide 506 is provided at one end of the telescopic bracket 505. A limiting slide hole 507 adapted to the limiting slide 506 is provided at the top of the lifting base 1. A telescopic locking hole 508 adapted to the telescopic bracket 505 is provided on one side of the lifting base 1. The fixed base plate 501 is connected and fixed to the stern deck by fastening bolts 510.

[0025] In this embodiment: the fixed base plate 501 is easily fixed to the stern deck by fastening bolts 510. The stern deck space is small, so the second servo motor 504 drives the second lead screw 503 to rotate. The second lead screw 503 is connected to the limiting slide 506, and the limiting slide 506 is connected to the telescopic bracket 505, which facilitates the telescopic bracket 505 to move telescopically, thereby driving the fixed base shell 401 to move telescopically. When idle, the fixed base shell 401 remains in a retracted state to save installation space. When the anchor chain needs to be winched, the lifting cylinder 502 drives the lifting base 1 to rise, and the second lead screw 503 rotates to extend the fixed base shell 401 outward for winching, which reduces obstruction to other equipment.

[0026] Specifically, the limiting baffle 202 facilitates the limiting of the hoisting of the anchor chain body 3, preventing the anchor chain body 3 from detaching from the hoisting roller 204 and reducing the possibility of the anchor chain body 3 becoming entangled. An AC motor 205 drives the hoisting roller 204 to rotate, facilitating the hoisting operation of the anchor chain body 3. While the AC motor 205 drives the hoisting roller 204, the speed needs to be slowed down to aid the auxiliary winding mechanism 4 in winding. A connecting clip 206 fixes the drive gear 207 to the hoisting roller 204. The rotation of the hoisting roller 204 drives the drive gear 207 to rotate. The drive gear 207 meshes with the reduction gear 208, improving the stability of the uniform rotation of the hoisting roller 204 and aiding in winding. The winding mechanism 4 facilitates the limiting control of the winding of the anchor chain body 3, preventing excessive winding speed from causing uneven stacking and entanglement of the anchor chain bodies 3, which would affect the winching effect of the ship's anchor chain winch. The anchor chain body 3 is unwound by passing one end through the anchor chain sleeve 412. The anchor chain sleeve 412 facilitates the limiting and fixing of the anchor chain body 3. The anchor chain sleeve 412 is movably fixed to the rotating shaft 411 on the clamping support plate 410 via a fixed support block 413 and a rotating groove 414, allowing for easy adjustment of the angle of the anchor chain sleeve 412 as the anchor chain body 3 is wound. The first servo motor 404 drives the first lead screw 403 to rotate, and the rotation of the first lead screw 403 drives the lead screw nut 405 to rotate. The movement of the sliding block 406 causes the sliding slider 406 to reciprocate within the sliding hole 407. The sliding block 406 then causes the anchor chain sleeve 412 to reciprocate, facilitating uniform winding of the auxiliary winch roller 204. As the anchor chain sleeve 412 moves, the anchor chain body 3 winds around layer by layer, reducing the risk of tangling and improving winch stability. The auxiliary roller 417 is placed below and in contact with the anchor chain body 3. The rotation of the auxiliary roller 417 facilitates sliding of the anchor chain body 3, reducing the obstruction of the anchor chain sleeve 412 to the winch's winding limit, thus improving the smoothness and speed of winch operation. The fixed base plate 501... The anchor chain is easily fixed to the stern deck by fastening bolts 510. Since the stern deck space is small, the second servo motor 504 drives the second lead screw 503 to rotate. The second lead screw 503 is connected to the limiting slide 506, which is connected to the telescopic bracket 505. This facilitates the telescopic bracket 505 to move telescopically, which in turn drives the fixed base 401 to move telescopically. When not in use, the fixed base 401 remains in a retracted state to save installation space. When the anchor chain needs to be winched, the lifting cylinder 502 drives the lifting base 1 to rise, and the second lead screw 503 rotates to extend the fixed base 401 outward for the winching operation, which reduces obstruction to other equipment.
