Description
Technical Field
[0001] This utility model relates to the field of anchor winch technology, and in particular to an electric anchor winch. Background Technology
[0002] A winch is a small, lightweight lifting device that uses a drum to wind a steel wire rope or chain to lift or pull heavy objects. Also known as a hoist, a winch can be used independently or as a component in machinery such as lifting, road construction, and mine hoisting. It is widely used because of its simple operation, large rope capacity, and convenient relocation.
[0003] Winches are frequently used on ships to raise or lower anchors to the seabed for anchoring and dropping operations, and are therefore also known as electric anchor winches. An electric anchor winch includes a winch drum that can rotate around its axis of rotation and can be used to wind a coilable intermediate object to raise or lower the anchor attached to the end of the coilable intermediate object. During the anchoring process, due to the extreme weight of the chain and anchor, the anchor chain can easily cause the drum to back up, which can not only prevent the anchoring operation from being completed smoothly, but may also damage the power unit of the electric anchor winch.
[0004] To solve the above problems, there is an urgent need for an electric anchor winch. Utility Model Content
[0005] The purpose of this utility model is to provide an electric anchor winch to solve the problem mentioned in the background art that the existing electric anchor winch is prone to the phenomenon of the winch drum reversing during the anchoring process due to the extremely heavy weight of the anchor chain. This not only causes the anchoring work to be unable to be completed smoothly, but may also damage the power unit of the electric anchor winch.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric anchor winch, comprising a base plate, a cavity being provided at the top of the base plate, two vertical plates being fixedly connected to the top of the base plate, and a drum being rotatably connected between the two vertical plates via a first rotating shaft, the drum comprising two circular plates symmetrically distributed on the left and right, a reduction gearbox and a drive motor being fixedly connected to the top of the base plate, the output end of the drive motor and the left end of the first rotating shaft being fixedly connected to the input end and the output end of the reduction gearbox, respectively, and a second braking assembly for braking the drum being connected to the top of the base plate;
[0007] The second braking assembly includes two pairs of hydraulic cylinders fixedly connected to the top of the base plate in a rectangular shape. Two clamping plates are symmetrically fixedly connected between the output ends of the two pairs of hydraulic cylinders. The two clamping plates are located directly above the two circular plates. Two concave arc grooves are symmetrically opened at the bottom of the two clamping plates. The two concave arc grooves can respectively abut and fit against the top surface of the two circular plates.
[0008] Preferably, the top plate of the base plate is provided with a first braking assembly for braking the circular plates. The first braking assembly is located directly below the two circular plates. The advantage of this arrangement is that by braking the circular plates at the bottom of the circular plates with the first braking assembly, and then cooperating with the second braking assembly to brake the circular plates at the top of the circular plates, the braking effect on the drum can be significantly improved. This effectively prevents the drum from being pulled by the anchor chain and causing a large overturning when anchoring, and avoids damage to the internal parts of the reduction gearbox and the drive motor.
[0009] Preferably, the first braking assembly includes two symmetrical first rotating arms, each located directly below two circular plates. Two first mounting cavities are symmetrically formed at the bottom ends of the two first rotating arms. The front inner wall of each first mounting cavity penetrates the front wall of the first rotating arm. Two connecting blocks are symmetrically rotatably connected between the left and right inner walls of the two first mounting cavities via a first rotating rod and a first torsion spring. The bottoms of the two connecting blocks are connected to the top of the base plate. Two second mounting cavities are symmetrically formed at the top ends of the two first rotating arms. The rear inner walls of the two second mounting cavities penetrate the rear walls of the two first rotating arms. Two second rotating arms are symmetrically rotatably connected between the left and right inner walls of the two second mounting cavities via a second rotating rod and a second torsion spring. Two first rollers are symmetrically rotatably connected to the top ends of the two second rotating arms. The first braking assembly also includes two sets of slots symmetrically formed on the outer circumferential surfaces of the two circular plates. Each set of multiple slots is annularly and equidistantly formed on the outer circumferential surface of the circular plate. The two first rollers can be symmetrically inserted into adjacent slots. The included angle between the first and second rotating arms is less than 180 degrees. The first braking assembly also includes two sets of first support rods and two sets of second support rods symmetrically fixedly connected to the top of the base plate. The two sets of second support rods are located directly behind the two sets of first support rods, and directly in front of the two first rotating arms. The advantage of this arrangement is that, by inserting the first roller into the adjacent slot, the first rotating arm can swing normally when the drum is raising the anchor, thus not hindering the anchoring operation. When the drum reverses under the pull of the anchor chain, the second rotating arm is forced to rotate in the opposite direction. At this time, the second mounting cavity will prevent the second rotating arm from rotating. When the first arm rotates in the opposite direction, it will cause the second arm to swing forward. This avoids a rigid impact between the second arm and the slot, preventing damage to the second arm. Then, the first and second support rods will prevent the first arm from swinging forward too much, thus effectively blocking the rotation of the circular plate. This brakes the circular plate to prevent it from continuing to reverse, ensuring the braking effect and reliability of the drum. When releasing the anchor, the second arm can be rotated to the bottom and fixed, thus preventing the second arm from contacting the circular plate and hindering the normal operation of the anchor release.
[0010] Preferably, the second braking assembly further includes two sets of clamping blocks symmetrically fixedly connected to the top walls of two concave arc grooves at the bottom of the two clamping plates. Two sets of second rollers are symmetrically rotatably connected to the two sets of clamping blocks. The bottom ends of the second rollers and clamping blocks can be inserted into adjacent slots. Each set of multiple clamping blocks is arranged in a ring, and their corresponding axis coincides with the axis of the concave arc groove. The advantage of this arrangement is that by inserting the two sets of clamping blocks and the two sets of second rollers into adjacent slots, the circular plate can be braked more reliably, improving the braking effect and reliability of the drum. Furthermore, the second rollers can achieve rolling friction with the outer circumferential surface of the circular plate when not inserted into the slot, thus avoiding severe friction between the bottom of the clamping blocks and the outer circumferential surface of the circular plate, protecting the circular plate, and improving the reliability and practicality of the winch.
[0011] Preferably, the first braking assembly further includes two first fixing blocks symmetrically fixedly connected to the top of the base plate, two second fixing blocks symmetrically fixedly connected to the top of the base plate, two guide rods symmetrically fixedly connected between the adjacent sides of the two first fixing blocks and the two second fixing blocks, two moving blocks symmetrically and movably sleeved between the outer peripheral surfaces of the two pairs of guide rods, and the bottoms of the two connecting blocks symmetrically and fixedly connected to the top surfaces of the two guide rods. The advantage of this arrangement is that when the first and second rotating arms swing forward in the reverse direction of the circular plate, the moving blocks can drive the first and second rotating arms to move forward a small distance. This can further improve the buffering effect between the second rotating arm and the slot, and further reduce the impact force on the second rotating arm while effectively braking the circular plate, thus protecting the safety of the second rotating arm.
[0012] Preferably, the first braking assembly further includes collision sensors symmetrically fixedly connected within two second fixed blocks. The two collision sensors can respectively sense the impact on the back of the two first fixed blocks. The advantage of this arrangement is that when the drum flips and, driven by the second and first rotating arms, moves the moving block forward and impacts the back of the first fixed block, the collision sensors can receive the collision signal and activate the hydraulic cylinder to drive the clamping plate, clamping block, and second roller downward until they are inserted into the adjacent slot. This allows the first braking assembly and the second braking assembly to work closely together to reliably brake the drum's reversal, protecting the safety of the winch.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] 1. In this utility model, by setting a second braking component, during the anchoring process, once the drum reverses under the pull of the anchor chain, the hydraulic cylinder can be activated to drive the two clamping plates to move downward until the inner top walls of the two concave arc grooves are tightly pressed against the top surfaces of the two circular plates. In this way, the circular plates can be clamped to prevent them from continuing to reverse, protecting the safety of the reduction gearbox and the drive motor, and effectively improving the safety and reliability of the winch.
[0015] 2. In this utility model, by setting a first braking component, the first braking component brakes the circular plate at the bottom of the circular plate, and then cooperates with the second braking component to brake the circular plate at the top of the circular plate, which can significantly improve the braking effect on the drum, effectively prevent the drum from being pulled by the anchor chain during anchoring and causing a large-scale overturning, and avoid damage to the internal parts of the reduction gearbox and the drive motor.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please refer to Figures 1-5 An electric anchor winch is shown, including a base plate 1. A cavity 11 is provided on the top of the base plate 1 to allow the anchor chain to pass smoothly through the base plate 1 to ensure that the anchoring and anchoring operations can be carried out smoothly. Two vertical plates 2 are fixedly connected to the top of the base plate 1. A drum 3 is rotatably connected between the two vertical plates 2 through a first rotating shaft. The drum 3 includes two circular plates 31 symmetrically distributed on the left and right. A reduction gearbox 12 and a drive motor 13 are fixedly connected to the top of the base plate 1. The output end of the drive motor 13 and the left end of the first rotating shaft are fixedly connected to the input end and the output end of the reduction gearbox 12, respectively. A second braking assembly 5 for braking the drum 3 is connected to the top of the base plate 1.
[0025] The second braking assembly 5 includes two pairs of hydraulic cylinders 51 fixedly connected to the top of the base plate 1 in a rectangular shape. Two clamping plates 52 are symmetrically fixedly connected between the output ends of the two pairs of hydraulic cylinders 51. The two clamping plates 52 are located directly above the two circular plates 31. Two concave arc grooves are symmetrically opened at the bottom of the two clamping plates 52. The two concave arc grooves can respectively abut and fit against the top surface of the two circular plates 31.
[0026] refer to Figures 1-4 The top plate of the base plate 1 is provided with a first braking assembly 4 for braking the circular plates 31. The first braking assembly 4 is located directly below the two circular plates 31.
[0027] Specifically, by braking the circular plate 31 at the bottom of the first braking component 4 and braking the circular plate 31 at the top of the second braking component 5, the braking effect on the drum 3 can be significantly improved, effectively preventing the drum 3 from being pulled by the anchor chain and causing a large overturning when anchoring, thus avoiding damage to the internal parts of the reduction gearbox 12 and the drive motor 13.
[0028] refer to Figures 1-4The first braking assembly 4 includes two symmetrical first rotating arms 41, located directly below two circular plates 31. Two first mounting cavities 42 are symmetrically formed at the bottom ends of the two first rotating arms 41. The front inner wall of each first mounting cavity 42 penetrates the front wall of the first rotating arm 41. Two connecting blocks 43 are symmetrically rotatably connected between the left and right inner walls of the two first mounting cavities 42 via a first rotating rod and a first torsion spring. The bottoms of the two connecting blocks 43 are connected to the top of the base plate 1. Two second mounting cavities 44 are symmetrically formed at the top ends of the two first rotating arms 41. The rear inner walls of the two second mounting cavities 44 penetrate the rear walls of the two first rotating arms 41. The left and right inner walls of the two second mounting cavities 44 are connected via a second rotating rod and a second torsion spring. The spring is symmetrically rotatably connected to two second rotating arms 45. The top ends of the two second rotating arms 45 are symmetrically rotatably connected to two first rollers 46. The first braking assembly 4 also includes two sets of slots 47 symmetrically opened on the outer peripheral surfaces of the two circular plates 31. Each set of multiple slots 47 is opened in a ring at equal angles on the outer peripheral surface of the circular plate 31. The two first rollers 46 can be symmetrically inserted into the adjacent slots 47. The included angle between the first rotating arms 41 and the second rotating arms 45 is less than 180 degrees. The first braking assembly 4 also includes two sets of first support rods 48 and two sets of second support rods 49 symmetrically fixedly connected to the top of the base plate 1. The two sets of second support rods 49 are located directly behind the two sets of first support rods 48 and directly in front of the two first rotating arms 41.
[0029] Specifically, by inserting the first roller 46 into the adjacent slot 47, the first rotating arm 41 can swing normally when the drum 3 is anchoring, thus not hindering the anchoring operation. When the drum 3 reverses under the pull of the anchor chain, the second rotating arm 45 is forced to rotate in the opposite direction. At this time, the second mounting cavity 44 will prevent the second rotating arm 45 from rotating in the opposite direction. The first rotating arm 41 will then drive the second rotating arm 45 to swing forward, thus avoiding rigid impact between the second rotating arm 45 and the slot 47 and preventing damage to the second rotating arm 45. Then, the first support rod 48 and the second support rod 49 will prevent the first rotating arm 41 from swinging forward significantly, thus effectively blocking the rotation of the circular plate 31. This brakes the circular plate 31 to prevent it from continuing to reverse, ensuring the braking effect and reliability of the drum 3. When anchoring, the second rotating arm 45 can be rotated to the bottom and fixed, thus preventing the second rotating arm 45 from contacting the circular plate 31 and hindering the normal anchoring operation.
[0030] refer to Figure 1 , Figure 2 and Figure 5The second braking assembly 5 also includes two sets of clamping blocks 53 symmetrically fixedly connected to the top walls of two concave arc grooves at the bottom of the two clamping plates 52. The two sets of clamping blocks 53 are symmetrically rotatably connected to two sets of second rollers 54. The bottom ends of the second rollers 54 and the clamping blocks 53 can be inserted into the adjacent slots 47. Each set of multiple clamping blocks 53 is arranged in a ring and the corresponding axis coincides with the axis of the concave arc groove.
[0031] Specifically, by inserting two sets of clamping blocks 53 and two sets of second rollers 54 into adjacent slots 47, the circular plate 31 can be braked more reliably, improving the braking effect and reliability of the drum 3. Furthermore, the second rollers 54 can roll against the outer circumference of the circular plate 31 when not inserted into the slots 47, thus avoiding severe friction between the bottom of the clamping blocks 53 and the outer circumference of the circular plate 31, protecting the safety of the circular plate 31, and improving the reliability and practicality of the winch.
[0032] refer to Figure 4 The first braking assembly 4 also includes two first fixing blocks 410 symmetrically fixedly connected to the top of the base plate 1, two second fixing blocks 411 symmetrically fixedly connected to the top of the base plate 1, two guide rods 412 symmetrically fixedly connected between the sides of the two first fixing blocks 410 and the two second fixing blocks 411 that are close to each other, two moving blocks 413 symmetrically and movably sleeved between the outer peripheral surfaces of the two pairs of guide rods 412, and the bottom of the two connecting blocks 43 symmetrically fixedly connected to the top surface of the two guide rods 412.
[0033] Specifically, when the circular plate 31 reverses and swings forward, the moving block 413 can drive the first rotating arm 41 and the second rotating arm 45 to move forward a small distance. This can further improve the buffering effect between the second rotating arm 45 and the slot 47, and further reduce the impact force on the second rotating arm 45 while effectively braking the circular plate 31, thus protecting the safety of the second rotating arm 45.
[0034] refer to Figure 4 The first braking assembly 4 also includes collision sensors symmetrically fixedly connected in two second fixing blocks 411. The two collision sensors can respectively sense the impact on the back of the two first fixing blocks 410. The collision sensors are connected to the control computer, and the control computer is connected to the hydraulic cylinder 51.
[0035] Specifically, when the drum 3 flips and is pushed forward by the second rotating arm 45 and the first rotating arm 41, causing the moving block 413 to move forward and collide with the back of the first fixed block 410, the collision sensor can receive the collision signal and activate the hydraulic cylinder 51 to drive the clamping plate 52, the clamping block 53 and the second roller 54 to move downward until they are inserted into the adjacent slot 47. This allows the first braking assembly 4 and the second braking assembly 5 to work closely together to reliably brake the reversal of the drum 3, thus protecting the safety of the winch.
[0036] Working principle: When the drum 3 is anchoring, if the drum 3 reverses due to the tension of the anchor point, the circular plate 31 will reverse, and the second rotating arm 45 inserted into the slot 47 will be pushed and swing forward. At this time, the second mounting cavity 44 will prevent the second rotating arm 45 from rotating in the opposite direction. The first rotating arm 41 will drive the second rotating arm 45 to swing forward. This can avoid rigid impact between the second rotating arm 45 and the slot 47, and prevent damage to the second rotating arm 45. Then, the first support rod 48 and the second support rod 49 will prevent the first rotating arm 41 from swinging forward significantly, thereby effectively blocking the rotation of the circular plate 31. This can brake the circular plate 31 to prevent it from continuing to reverse, ensuring the braking effect and reliability of the drum 3.
[0037] Furthermore, when the circular plate 31 reverses and swings forward, the moving block 413 can drive the first rotating arm 41 and the second rotating arm 45 to move forward a small distance. This can further improve the buffering effect between the second rotating arm 45 and the slot 47. Under the premise of effectively braking the circular plate 31, the impact force on the second rotating arm 45 is further reduced, thus protecting the safety of the second rotating arm 45.
[0038] At the same time, when the moving block 413 hits the back of the first fixed block 410, the collision sensor can receive the collision signal and activate the hydraulic cylinder 51 to drive the clamping plate 52, the clamping block 53 and the second roller 54 to move downward until they are inserted into the adjacent slot 47. This allows the first braking assembly 4 and the second braking assembly 5 to work closely together to reliably brake the reverse rotation of the drum 3 and protect the safety of the winch.
[0039] During the anchoring operation, the second rotating arm 45 can be rotated to the bottom and fixed. For example, the second rotating arm 45 rotated to the bottom and the first rotating arm 41 can be fixedly connected together by steel wire. This can prevent the second rotating arm 45 from contacting the circular plate 31 and thus avoid hindering the normal progress of the anchoring operation.
[0040] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
