Description

Technical Field

[0001] The present invention relates to the field of ships, and particularly to a ship anchoring device based on intelligent hydraulic drive. Background Art

[0002] Traditional ship anchoring devices driven by hydraulic pressure have achieved efficient retraction and deployment of ship anchors. However, during the retraction and deployment of the ship anchor, the anchor chain may not be retracted and deployed smoothly enough, affecting the anchoring effect. In addition, in the navigation state, if the ship anchor is not properly fixed, it may collide with the hull due to the shaking of the ship. Over time, this may not only cause damage to the ship anchor and the hull, but also affect the navigation safety.

[0003] The currently publicly disclosed ship anchor fixing device and ship with Chinese authorization announcement number CN116902138B include a fixing box. A connecting hole is provided at the top end of the fixing box, and the anchor chain passes through the connecting hole and is connected to a winding device on the hull. A receiving hole for allowing the anchor body to enter the fixing box is provided at the bottom end of the fixing box. A push-out clamping member is provided inside the fixing box, and the anchor body can be clamped and fixed inside the fixing box by the clamping member. A guide wheel is rotatably provided at the top end inside the fixing box. The clamping member includes a first spring and a clamping plate provided at the end of the first spring. The first spring is used to push the clamping plate to clamp the anchor body. A driving assembly is also provided inside the fixing box, and the driving assembly can drive the clamping plate to compress or release the first spring. There are two clamping plates opposed to each other inside the fixing box.

[0004] According to the above patent, the patent can clamp the anchor body through the clamping member inside the fixing box, so that the ship anchor will not collide with the hull, and the random shaking of the anchor body can also be prevented by the clamping member. At the same time, the guide wheel can guide the winding of the anchor chain, making the winding operation of the anchor chain smoother and more reliable. However, in long-term use, the first spring in the clamping member may lose its original elasticity due to fatigue, resulting in the clamping plate being unable to effectively fix the anchor body, thereby affecting the reliability. And during the process of lowering the anchor body, if the lowering speed is too fast, it is also easy to cause the anchor chain to break or physical damage to the anchor itself. Therefore, there is currently a need for a ship anchoring device based on intelligent hydraulic drive that can achieve smooth lowering and recovery of the anchor chain, ensure the stability of the anchor body in the non-use state, and prevent it from colliding with the hull and random shaking. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, a ship anchoring device based on intelligent hydraulic drive is provided. Through the cooperation of the guide wheel and the clamping plate, the speed control and stable locking during the lowering and recovery of the ship anchor are realized, reducing the risk of sudden impact during the lowering of the ship anchor and ensuring that the position of the ship anchor remains fixed during the retraction, preventing accidental collision.

[0006] To solve the problems of the existing technology, the present invention provides a ship anchoring device based on intelligent hydraulic drive, including a frame. A hydraulic drive mechanism for driving the anchor chain to retract and release the ship anchor is provided on the frame. A stabilizing mechanism for keeping the ship anchor retracted and released stably is also provided on the frame. The stabilizing mechanism includes guide wheels symmetrically arranged on both sides of the anchor chain and a locking structure that can cooperate with the two guide wheels to fix the ship anchor. Each guide wheel can move on the frame towards the direction of the anchor chain. A rubber ring is sleeved on each guide wheel. When the two guide wheels approach each other and squeeze the anchor chain, the lowering of the ship anchor is in a decelerated state, and at the same time, the locking structure remains in an unlocked state. When the two guide wheels move away from each other and do not squeeze the anchor chain, the retraction of the ship anchor is in a uniform speed state, and at the same time, the locking structure remains in a state of waiting for self-locking.

[0007] Preferably, the locking structure has clamping plates symmetrically arranged on both sides of the anchor chain and located below the guide wheels. Each clamping plate can move on the frame towards the direction of the ship anchor. When the ship anchor is clamped between the two clamping plates, the ship anchor is in a locked state, so that the ship anchor remains stable relative to the ship.

[0008] Preferably, the locking structure further has anchor rods arranged on the ship anchor and extending towards the direction of each clamping plate at both ends. A clamping groove capable of clamping the corresponding end of the anchor rod therein is formed on each clamping plate.

[0009] Preferably, a rubber layer capable of buffering the extrusion force of the clamping plate on the end of the anchor rod and increasing the friction force is provided in the clamping groove formed on each clamping plate.

[0010] Preferably, sliders for each clamping plate to be rotatably connected thereto are slidably arranged on the frame. An elastic member capable of pressing the clamping plate inward is provided on the slider. A slope is further provided on the inner side of the lower end of each clamping plate. When the end of the anchor rod passes through the clamping plate along the slope, the clamping plate is pushed to rotate outward, and at this time, the elastic member is in a compressed state.

[0011] Preferably, both ends of the anchor rod are spherical structures. The rubber layer on each clamping plate has a notch capable of embedding the end of the anchor rod therein. When the clamping plate is pressed and reset, the end of the anchor rod falls into the notch on the rubber layer and is in a wrapped state.

[0012] Preferably, a stop block for blocking the slider from moving inward continuously is provided on the frame. When the two sliders are respectively in contact with the corresponding stop blocks, the two clamping plates are in a state of waiting for self-locking, forming a self-locking area.

[0013] Preferably, an elastic clamp capable of adaptively clamping the anchor rod is provided on the frame. The elastic clamp has a guiding edge for guiding the anchor rod into it. The elastic clamp and the clamping plate jointly form the self-locking area for laterally and vertically limiting the ship anchor.

[0014] Preferably, a hydraulic cylinder is provided on the frame and cooperates with the hydraulic drive mechanism to synchronously drive the relative movement of the two guide wheels. A first linkage is provided between the working end of the hydraulic cylinder and each guide wheel.

[0015] Preferably, a second linkage is provided between the working end of the hydraulic cylinder and the slider. When the guide wheel is driven to approach or move away from the anchor chain, the slider moves synchronously outward or inward under the drive of the second linkage, so that the clamping plate moves away from or approaches the anchor.

[0016] The beneficial effects of this application compared with the prior art are: 1. By arranging the guide wheels on both sides of the anchor chain, the present invention can accurately move towards the direction of the anchor chain, realizing the speed control and stability improvement during the lowering and recovery of the anchor.

[0017] When it is necessary to slow down the lowering of the anchor, the two guide wheels approach each other and gradually squeeze the anchor chain in the middle. As the distance between the guide wheels decreases, the pressure applied to the anchor chain increases, reducing the moving speed of the anchor chain, thereby realizing the smooth deceleration of the lowering of the anchor.

[0018] On the contrary, when recovering the anchor, the guide wheels move away from each other and no longer squeeze the anchor chain, enabling the anchor chain to be quickly and evenly pulled back onto the ship under a state of smaller resistance. This not only ensures the smooth operation of the anchor chain but also effectively reduces the risks brought by sudden impacts or overly fast lowering, greatly improving the safety and reliability of ship mooring.

[0019] 2. By means of the clamping plates on both sides of the anchor chain, the present invention can move inward on the frame and accurately clamp the anchor chain, realizing the effective locking and stable fixation of the anchor.

[0020] When the clamping plates gradually approach and finally clamp the anchor chain, the two ends of the anchor rod just align and enter the card slots on the clamping plates. As the clamping plates close, the end of the anchor rod is firmly stuck in the card slot with a rubber layer, ensuring the stable locking of the anchor. The rubber layer increases the friction between the anchor rod and the clamping plates, preventing the anchor rod from loosening or slipping due to vibration or other external forces.

[0021] In addition, the clamping plates slide on the frame to a predetermined position through the sliders and automatically complete the locking process of the anchor rod with the help of the elastic members. This not only enhances the stability of the locking structure, effectively preventing the accidental loosening or sliding of the anchor, but also improves the safety and reliability of the ship in various sea conditions, ensuring that the position of the anchor relative to the ship remains fixed even under harsh conditions, preventing the anchor from colliding with the ship, thereby guaranteeing the safety and reliability of the entire anchoring device.

[0022] 3. By clamping the upper anchor rod of the ship anchor with an elastic clamp, the ship anchor is further stabilized. As the ship anchor is retrieved and the anchor rod approaches the clamping plate, the elastic clamp can first guide the anchor rod into it, ensuring effective clamping regardless of the position and angle of the anchor rod, thereby ensuring that the anchor rod is firmly fixed within the self-locking area.

[0023] At the same time, the elastic clamp and the clamping plate work together to jointly form a self-locking area that can limit the position both horizontally and vertically, ensuring that the anchor rod does not move unnecessarily in any direction. This not only makes the locking and releasing processes of the ship anchor more efficient and reliable, but also significantly improves the safety and stability of the ship in various sea conditions, effectively preventing the ship anchor from loosening or slipping due to external forces and ensuring the safety of the ship.

[0024] 4. The present invention realizes the synchronous movement of the guide wheel by using the first linkage between the piston rod and the sliding seat, thereby precisely controlling the speed of the anchor chain retraction and release. At the same time, the second linkage between the piston rod and the slider is used to realize the synchronous movement of the clamping plate, and then the unlocking and self-locking operations of the clamping plate on the anchor rod are realized. It not only effectively regulates the speed of the anchor chain retraction and release, but also ensures that the ship anchor can be firmly locked after being retrieved, improving the operation efficiency and safety of the entire anchoring device.

Detailed implementation manners

[0036] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0037] See Figures 1 - 6 As shown, a ship anchoring device based on intelligent hydraulic drive includes a frame 1. A hydraulic drive mechanism for driving the retraction and release of the anchor chain 21 to anchor the ship 2 is provided on the frame 1. A stabilizing mechanism for keeping the ship anchor 2 retracted and released stably is also provided on the frame 1. The stabilizing mechanism includes guide wheels 3 symmetrically arranged on both sides of the anchor chain 21 and a locking structure 4 that can cooperate with the two guide wheels 3 to fix the ship anchor 2. Each guide wheel 3 can move on the frame 1 towards the direction of the anchor chain 21. A rubber ring 31 is sleeved on each guide wheel 3. When the two guide wheels 3 approach each other and squeeze the anchor chain 21, the lowering of the ship anchor 2 is in a decelerated state, and at the same time, the locking structure 4 remains in an unlocked state. When the two guide wheels 3 move away from each other and do not squeeze the anchor chain 21, the retraction of the ship anchor 2 is in a uniform speed state, and at the same time, the locking structure 4 remains in a state of waiting for self-locking.

[0038] The hydraulic drive mechanism is not shown in the figure.

[0039] When the ship needs to lower the anchor chain 21 to achieve berthing, the hydraulic drive mechanism on the rack 1 starts to work. By controlling the pressure change in the internal oil circuit, it drives the sprocket that winds the anchor chain 21 to rotate, thereby realizing the release of the anchor chain 21. When it is necessary to perform a decelerated lowering operation on the ship anchor 2, the guide wheels 3 arranged on both sides of the anchor chain 21 move towards the direction of the anchor chain 21. The two guide wheels 3 approach each other and gradually squeeze the anchor chain 21 in the middle. As the distance between the guide wheels 3 decreases, the pressure they exert on the anchor chain 21 increases, resulting in a decrease in the moving speed of the anchor chain 21, thus realizing the smooth decelerated lowering of the ship anchor 2.

[0040] Meanwhile, during the lowering process of the ship anchor 2, the locking structure 4 remains unlocked, allowing the anchor chain 21 to freely pass through the guide wheels 3 and the locking structure 4, ensuring the smoothness of the entire lowering process. This enables the precise lowering of the ship anchor 2 even under harsh sea conditions, reducing the risks that may be brought about by sudden impacts or overly fast lowering.

[0041] On the contrary, when it is necessary to recover the ship anchor 2, the hydraulic drive mechanism works in reverse, driving the sprocket to reverse and pulling back the anchor chain 21. At this time, the two guide wheels 3 move away from each other and no longer squeeze the anchor chain 21, enabling the anchor chain 21 to be quickly and evenly pulled back onto the ship under a state of less resistance.

[0042] Meanwhile, the locking structure 4 is in a state of waiting for self-locking, ready to immediately fix the position of the ship anchor 2 after the anchor chain 21 is completely retracted, preventing the ship anchor 2 from colliding with the ship and improving the stability of the ship anchor 2 after recovery.

[0043] See Figures 1 - 4 and Figures 6 - 10 As shown, the locking structure 4 has clamping plates 41 symmetrically arranged on both sides of the anchor chain 21 and located below the guide wheels 3. Each of the clamping plates 41 can move on the rack 1 towards the direction of the ship anchor 2. When the ship anchor 2 is clamped between the two clamping plates 41, the ship anchor 2 is in a locked state, making the ship anchor 2 remain stable relative to the ship.

[0044] When it is necessary to lock the ship anchor 2, the clamping plates 41 located on both sides of the anchor chain 21 and below the guide wheels 3 move inward on the rack 1 and can accurately approach the middle anchor chain 21.

[0045] As the two clamping plates 41 gradually approach and finally clamp the anchor chain 21, the ship anchor 2 is firmly fixed between them. At this time, the ship anchor 2 enters the locked state. This ensures that the ship anchor 2 remains stable relative to the ship, prevents it from making unnecessary movements due to external forces, and guarantees the safety and stability of the ship during berthing.

[0046] See Figures 1 - 6As shown, the locking structure 4 further has an anchor rod 22 provided on the ship anchor 2 and extending towards each clamping plate 41 at both ends, and each clamping plate 41 is provided with a clamping groove capable of clamping the corresponding end of the anchor rod 22 therein.

[0047] When the clamping plate 41 moves towards the ship anchor 2 and clamps the anchor chain 21, the two ends of the anchor rod 22 are exactly aligned and enter the corresponding clamping grooves. With the final closing of the clamping plate 41, the ends of the anchor rod 22 are firmly clamped in the clamping grooves, thus ensuring that the ship anchor 2 is stably locked.

[0048] This not only enhances the stability of the locking structure 4, but also effectively prevents the accidental loosening or sliding of the ship anchor 2 caused by external forces, greatly improving the safety and reliability during the ship's voyage. Even in harsh sea conditions, it can ensure that the position of the ship anchor 2 relative to the ship remains fixed, ensuring the safety and stability of the ship.

[0049] See Figures 2 - 4 and Figures 6 - 10 As shown, a rubber layer 411 capable of buffering the extrusion force of the clamping plate 41 on the end of the anchor rod 22 and increasing the friction force is provided in each clamping groove opened on the clamping plate 41.

[0050] When the clamping plate 41 moves towards the ship anchor 2 and clamps the end of the anchor rod 22 into the clamping groove opened therein, the rubber layer 411 in the clamping groove can provide a buffering effect while the clamping plate 41 exerts an extrusion force on the end of the anchor rod 22, reducing the direct impact force and protecting the anchor rod 22 and the clamping plate 41 from damage.

[0051] In addition, the material properties of the rubber layer 411 can significantly increase the friction force, ensuring that the anchor rod 22 is firmly held in the clamping groove and preventing loosening or slipping caused by vibration or other external forces. This not only extends the service life of the clamping plate 41, but also greatly enhances the reliability of the locking structure 4, enabling the ship to sail safely and stably in various sea conditions and reducing the risk of the ship anchor 2 accidentally hitting the ship.

[0052] See Figures 2 - 4 and Figures 6 - 10 As shown, sliders 42 for each clamping plate 41 to be rotatably connected thereto are slidably provided on the frame 1, an elastic member 421 capable of pressing the clamping plate 41 inward is provided on the slider 42, and slopes are provided on the inner sides of the lower ends of each clamping plate 41. When the end of the anchor rod 22 passes through the clamping plate 41 along the slope, the clamping plate 41 is pushed to rotate outward, and at this time the elastic member 421 is in a compressed state.

[0053] During the rising process of the ship anchor 2, the two clamping plates 41 slide on the frame 1 through the sliders 42 to a predetermined position and remain in a self-locking state. As the ship anchor 2 rises, the end of the anchor rod 22 first contacts the slope at the lower end of the clamping plate 41, prompting the clamping plate 41 to rotate around its rotation connection point with the slider 42, and at the same time compressing the elastic member 421 on the slider 42.

[0054] When the end of the anchor rod 22 passes along the slope through the clamping plate 41, the clamping plate 41 is gradually rotated and opened under the guidance of the slope, allowing the anchor rod 22 to pass through smoothly. Once the anchor rod 22 completely crosses the slope and enters the card slot on the clamping plate 41, the elastic member 421 returns to its original state and pushes the clamping plate 41 to close, and the end of the anchor rod 22 is caught in the card slot with the rubber layer 411.

[0055] The rubber layer 411 can not only buffer the extrusion force of the clamping plate 41 on the anchor rod 22, but also increase the friction force to ensure firm locking. In this way, after the anchor 2 rises to an appropriate position, the clamping plate 41 automatically completes the locking of the anchor rod 22, keeping the anchor 2 stable relative to the ship. It ensures that the anchor 2 can smoothly transition to the safe locking state during the rising process, preventing the anchor 2 from colliding with the ship.

[0056] See Figures 2 - 4 and Figures 6 - 10 As shown, both ends of the anchor rod 22 are spherical structures, and the rubber layer 411 on each clamping plate 41 has a notch capable of embedding the end of the anchor rod 22. When the clamping plate 41 is pressed and reset, the end of the anchor rod 22 sinks into the notch on the rubber layer 411 and is in a wrapped state.

[0057] The two ends of the anchor rod 22 being spherical structures helps to reduce the friction with the clamping plate 41 and enables the anchor rod 22 to pass more smoothly through the space between the clamping plates 41.

[0058] When the anchor 2 is rising, as the end of the anchor rod 22 passes along the slope at the lower end of the clamping plate 41, the clamping plate 41 is pressed and rotated open, allowing the anchor rod 22 to pass through smoothly. Once the end of the anchor rod 22 crosses the slope and reaches the position, the clamping plate 41 is reset under the action of the elastic member 421, and the end of the anchor rod 22 just sinks into the notch of the rubber layer 411, and at this time the sphere is completely wrapped by the rubber layer 411.

[0059] With the pressure of the clamping plate 41, not only the buffering characteristics of the rubber layer 411 are utilized to absorb the pressure of the clamping plate 41 on the anchor rod 22, but also the stability in the locked state is ensured by increasing the friction force. It avoids damage caused by hard contact, protects the anchor rod 22 and the clamping plate 41 from wear, and extends the service life. It improves the limiting and stabilizing effect on the anchor 2.

[0060] See Figures 2 - 4 and Figures 7 - 9 As shown, a stop block 43 for blocking the slider 42 from moving further inward is provided on the frame 1. When the two sliders 42 are in contact with the corresponding stop blocks 43 respectively, the two clamping plates 41 are in a state of waiting for self-locking, forming a self-locking area.

[0061] The stopper 43 limits the movement range of the slider 42, enabling the clamping plate 41 to accurately stop at a position suitable for capturing the end of the anchor rod 22, ensuring the accuracy of the subsequent locking action. In this state, the clamping plate 41 has been adjusted to the optimal position waiting for the entry of the anchor rod 22. Once the end of the anchor rod 22 arrives, the clamping plate 41 can quickly close and lock the anchor rod 22 under the action of the elastic member 421, achieving effective fixation of the ship anchor 2.

[0062] By presetting the position of the clamping plate 41, the locking structure 4 can work reliably even in rough sea conditions, preventing the ship anchor 2 from failing to be correctly locked due to unexpected situations. Specifically, when the two sliders 42 respectively contact the corresponding stoppers 43, a preset locking preparation state is formed between the two clamping plates 41, ensuring that the clamping plate 41 can greet the end of the anchor rod 22 at the optimal position and angle and quickly complete the locking process, thereby ensuring the stability of the ship anchor 2 relative to the ship and improving the safety and reliability of the entire anchoring device.

[0063] See Figures 2 - 4 As shown, an elastic fixture 44 capable of adaptively clamping the anchor rod 22 is provided on the frame 1. The elastic fixture 44 has a guiding edge for guiding the anchor rod 22 into it. The elastic fixture 44 and the clamping plate 41 jointly form the self-locking area for laterally and vertically limiting the ship anchor 2.

[0064] When the anchor rod 22 approaches the elastic fixture 44 as the ship anchor 2 is retrieved, the guiding edge on the elastic fixture 44 guides the anchor rod 22 to smoothly enter the self-locking area. Since the elastic fixture 44 can adaptively clamp the anchor rod 22, it ensures that the anchor rod 22 can be effectively clamped regardless of its position and angle.

[0065] At the same time, the elastic fixture 44 and the clamping plate 41 act together to form a self-locking area that can limit both laterally and vertically. Within this area, the anchor rod 22 is firmly fixed, preventing the ship anchor 2 from moving unnecessarily in any direction. This makes the locking and releasing of the ship anchor 2 more efficient and reliable, ensuring the safety of the ship.

[0066] See Figures 2 - 4 and Figures 7 - 10 As shown, a hydraulic cylinder 5 is provided on the frame 1 and is used in cooperation with a hydraulic driving mechanism to synchronously drive the relative movement of the two guide wheels 3. A first linkage member 6 is provided between the working end of the hydraulic cylinder 5 and each guide wheel 3.

[0067] A hydraulic cylinder 5 is provided between every two sliding seats 32 on the same side.

[0068] The hydraulic cylinder 5 is composed of a cylinder barrel 51 and a piston rod 52 inserted therein. A piston sleeve 521 is provided at the upper end of the piston rod 52. An upper interface 511 and a lower interface 512 are respectively formed on the cylinder barrel 51 and can be connected to a hydraulic driving mechanism for part of the hydraulic oil to flow in and out.

[0069] Sliding seats 32 for each guiding wheel 3 to be rotatably connected are provided on the frame 1. A sliding groove for the sliding seat 32 to slide is formed on the frame 1. A first linkage 6 is hinged between each sliding seat 32 and the lower end of the piston rod 52. The first linkage 6 is of a plate structure.

[0070] When the piston rod 52 moves upward, the two sliding seats 32 approach each other driven by the first linkage 6. On the contrary, when the piston rod 52 moves downward, the two sliding seats 32 move away from each other driven by the first linkage 6. The speed control of the anchoring chain 21 being retracted and released by the two guiding wheels 3 is realized. That is, when lowering, the anchoring chain 21 is squeezed to slow down the falling speed of the anchor 2. When retracting, the anchoring chain 21 resumes the normal upward pulling speed, reducing the resistance during the upward pulling process and maintaining a stable upward speed of the anchor 2.

[0071] See Figures 2 - 4 and Figures 7 - 10 As shown, a second linkage 7 is provided between the working end of the hydraulic cylinder 5 and the slider 42. When the guiding wheel 3 is driven to approach or move away from the anchoring chain 21, the slider 42 moves outward or inward synchronously driven by the second linkage 7, so that the clamping plate 41 moves away from or approaches the anchor 2.

[0072] A second linkage 7 is hinged between each slider 42 and the lower end of the corresponding piston rod 52. The second linkage 7 is of a plate structure.

[0073] A guiding rod 422 for guiding the movement of the slider 42 is fixedly provided on the frame 1. A guiding opening for slidably sleeving on the guiding rod 422 is formed on the slider 42.

[0074] When the piston rod 52 moves upward, the slider 42 slides outward driven by the second linkage 7. On the contrary, when the piston rod 52 moves downward, the slider 42 slides inward driven by the second linkage 7. The unlocking and self-locking of the two clamping plates 41 in cooperation with the anchor rod 22 on the anchor 2 are realized, so that the anchor 2 remains stable after being retracted.

[0075] Through the guiding wheels 3 and the clamping plates 41 arranged on both sides of the anchoring chain 21, the present invention realizes the speed control and stable locking during the lowering and recovery processes of the anchor 2.

[0076] The guide wheel 3 can move precisely to squeeze or release the anchor chain 21, enabling the ship anchor 2 to be lowered smoothly with deceleration or retrieved quickly, reducing the risk of sudden impact and enhancing safety. The clamping plate 41 can automatically lock the anchor rod 22 under the action of the slider 42 and the elastic member 421, ensuring that the position of the ship anchor 2 remains fixed and preventing accidental collisions.

[0077] In addition, the elastic fixture 44 guides the anchor rod 22 into the self-locking area and cooperates with the clamping plate 41 to form lateral and vertical limits, ensuring that the anchor rod 22 is stable and immovable. This not only improves the operation efficiency and reliability of the anchoring device but also significantly enhances the safety and stability of the ship in various sea conditions, guaranteeing the safety of the ship.

[0078] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed. However, it should not be construed as a limitation on the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
