Description

Technical Field

[0001] This invention relates to the field of ship transfer technology, and more particularly to a ship transfer device. Background Technology

[0002] Currently, the main methods for ship transfer operations include the following three: 1) Wire rope launching method: Personnel first board the transfer vessel (usually a small boat), and then a winch is used to lift the transfer vessel off the water or lower it back to the water. 2) Stern ramp method: The transfer vessel uses its own power to ascend the ramp and return to the mother ship, and similarly uses its own power to reverse away from the mother ship. 3) Stern tank method: A large, submerged compartment is opened at the stern of the ship. The transfer vessel drives directly into the compartment, and personnel board the boat from the compartment or board the mother ship from the transfer vessel.

[0003] The aforementioned ship transfer equipment operations require multiple operators with high levels of experience. The deployment and retrieval of the transfer vessel involve numerous, cumbersome, and inefficient processes. Furthermore, during transfer operations, methods such as winch-based deployment or ramp-based deployment can easily cause strong impacts from seawater and waves on the transfer vessel, posing potential safety hazards to the transfer vessel and its crew. Additionally, the hoisting method carries a risk of injury due to the transfer vessel's swaying during the release of wire rope shackles or when connecting to the mother ship. Summary of the Invention

[0004] The purpose of this invention is to provide a ship transfer device to solve the technical problems of low efficiency and safety risks in the operation of existing transfer devices, thereby improving the operational efficiency and safety of ship transfer devices.

[0005] To achieve this objective, the technical solution adopted by the present invention is as follows:

[0006] The vessel's transshipment equipment includes:

[0007] A transfer assembly includes a transfer drive and a transfer frame. The transfer drive drives the transfer frame to reciprocate between a storage position within the equipment compartment and an extreme position extending out of the watertight door of the equipment compartment. The transfer frame includes a lifting guide rail extending along the height direction.

[0008] The transfer guide rail is installed on the side of the ship along the height direction; when the transfer frame moves to the limit position, the bottom end of the lifting guide rail is connected to the top end of the transfer guide rail.

[0009] The lifting assembly includes a lifting drive and a lifting frame for launching and retrieving the docking boat. The lifting drive drives the lifting frame to move up and down along the opposing lifting guide rail and the docking guide rail. The lifting frame has a docking position for docking personnel and a launching and retrieving position for launching and retrieving the docking boat on the docking guide rail. The water level is below the docking position and above the launching and retrieving position.

[0010] As an optional solution for ship transfer devices, the transfer frame also includes a base frame and diagonal braces. The lifting guide rail is mounted on the base frame, and the diagonal braces are inclined between the lifting guide rail and the base frame so that the transfer frame forms a triangular frame.

[0011] As an optional transshipment device for ships, the bottom of the frame is equipped with a set of wheels, the equipment compartment is provided with a slide rail, and the transfer drive unit drives the set of wheels to move along the slide rail between the storage position and the extreme position.

[0012] As an optional device for transshipment of ships, the bottom end of the frame is also equipped with a locking element, which cooperates with the slide rail to lock the transfer frame in the extreme position or unlock the transfer frame.

[0013] As an optional solution for the ship transfer device, the lifting frame includes a main frame body, and at least two roller assemblies are spaced apart along the width direction of the main frame body. The roller assembly includes a plurality of roller modules spaced apart along the length direction of the main frame body. The roller modules are inclined so that at least two of the roller assemblies form a V-shaped frame that is adapted to the bottom profile of the transfer vessel.

[0014] As an optional solution for ship transfer devices, the roller module includes a roller frame, a roller shaft, and rollers. The roller frame is mounted on the main frame, and the rollers are rotatably mounted at both ends of the roller shaft. The roller shaft is tilted and movably mounted on the roller frame so that the V-angle of the V-shaped frame is adjustable.

[0015] As an optional solution for the ship transfer device, a guardrail is provided on the side of the main frame away from the lifting guide rail, and the main frame and the guardrail form a U-shaped channel to accommodate the transfer vessel.

[0016] As an optional device for ship transfer, the inner wall of the guardrail is equipped with a cushioning pad.

[0017] As an optional solution for ship transfer equipment, the top of the lifting frame is provided with a fixed pulley, and a hoisting rope is wound on the fixed pulley. The lifting drive unit drives the lifting frame to move up and down along the opposite lifting guide rail and the transfer guide rail by winding and unwinding the hoisting rope.

[0018] As an optional solution for ship transfer devices, both the lifting guide rail and the transfer guide rail have track plates;

[0019] The lifting frame is provided with a first guide wheel and a second guide wheel. The first guide wheel is slidably engaged with both sides of the track plate in the width direction, and the second guide wheel is slidably engaged with both sides of the track plate in the thickness direction.

[0020] The beneficial effects of this invention are as follows:

[0021] The ship transfer device proposed in this invention includes a transfer assembly, a transfer guide rail, and a lifting assembly. When the transfer frame moves to its limit position, the bottom end of the lifting guide rail aligns with the top end of the transfer guide rail. A lifting drive unit drives the lifting frame to move up and down along the lifting and transfer guide rails. When the lifting frame moves to a connection position above the water surface, personnel can safely board and disembark. When the lifting frame moves to a deployment / retrieval position below the water surface, the transfer vessel can be deployed and retrieved. The ship transfer device proposed in this invention achieves automatic deployment and retrieval of transfer vessels, reducing manual intervention and improving the operational efficiency of the ship transfer device. Simultaneously, the aligned lifting and transfer guide rails guide and limit the movement of the lifting frame and transfer vessel, preventing them from swaying due to wind and waves, improving the stability of the lifting frame and transfer vessel's movement, ensuring safe boarding and disembarking of personnel, and enhancing the safety of the ship transfer device.

[0031] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, it should be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, not all of them.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Existing ship-to-ship transshipment systems require multiple operators with high levels of experience. The deployment and retrieval processes for the transshipment vessel are complex, cumbersome, and inefficient. Furthermore, during transshipment operations, methods such as winch-based deployment or ramp-based deployment can easily cause strong impacts from seawater and waves on the transshipment vessel, posing potential safety hazards to the transshipment vessel and its crew. Additionally, the hoisting method carries a risk of injury due to the transshipment vessel's swaying during the release of wire rope shackles or when connecting to the mother ship.

[0037] To solve the above problems, such as Figure 1 and Figure 2 As shown, this embodiment proposes a ship transfer device, which includes a transfer assembly 1, a transfer guide rail 2, and a lifting assembly 3. The transfer assembly 1 includes a transfer drive 11 and a transfer frame 12. The transfer drive 11 drives the transfer frame 12 to reciprocate between a stored position within the equipment compartment 10 and an extreme position extending out of the watertight door 101 of the equipment compartment 10. The transfer frame 12 includes a lifting guide rail 121 extending along the height direction (the height direction of the ship). The transfer guide rail 2 is installed along the height direction on the ship's side 100. When the transfer frame 12 moves to its extreme position, the bottom end of the lifting guide rail 121 is aligned with the top end of the transfer guide rail 2. The lifting assembly 3 includes a lifting drive and a lifting frame 31 for launching and retrieving the docking boat 20. The lifting drive drives the lifting frame 31 to move up and down along the opposing lifting guide rail 121 and the docking guide rail 2. The lifting frame 31 has a docking position for docking personnel and a launching and retrieving position for launching and retrieving the docking boat 20 on the docking guide rail 2. The water level is lower than the docking position and higher than the launching and retrieving position.

[0038] When the transfer frame 12 moves to its limit position, the bottom end of the lifting guide rail 121 aligns with the top end of the transfer guide rail 2. The lifting drive unit drives the lifting frame 31 to move up and down along the lifting guide rail 121 and the transfer guide rail 2. When the lifting frame 31 moves to the docking position above the water surface, personnel can safely board and disembark. When the lifting frame 31 moves to the deployment and retrieval position below the water surface, the docking vessel 20 can be deployed and retrieved. The ship transfer device in this embodiment realizes the automatic deployment and retrieval of the docking vessel 20, reduces manual intervention, and improves the operational efficiency of the ship transfer device. At the same time, the aligned lifting guide rail 121 and transfer guide rail 2 can guide and limit the lifting movement of the lifting frame 31 and the docking vessel 20, preventing the lifting frame 31 and the docking vessel 20 from swaying due to wind and waves, improving the stability of the lifting frame 31 and the docking vessel 20 during the lifting movement process, ensuring the safe boarding of personnel onto or off the docking vessel 20, and improving the safety of the ship transfer device.

[0039] like Figure 1 As shown, the vessel has an equipment compartment 10 that houses the transfer assembly 1, the lifting assembly 3, and the shuttle boat 20, as well as a passenger compartment 30 located below the equipment compartment 10. The equipment compartment 10 has a watertight door 101 that can be opened and closed, and the passenger compartment 30 has a cabin door 301 that can be opened and closed. During normal navigation, the watertight door 101 and the cabin door 301 remain closed. Two transfer rails 2 are installed along the height direction on the outer plating of the ship's side 100, and the passenger compartment 30 is located between the two transfer rails 2.

[0040] When the docking vessel 20 needs to be deployed, the watertight door 101 is opened, and the transfer drive 11 drives the transfer frame 12 from the storage position to the limit position. At this time, the bottom end of the lifting guide rail 121 is aligned with the top end of the transfer guide rail 2. The lifting drive drives the lifting frame 31 to slide from the lifting guide rail 121 onto the transfer guide rail 2. At the same time, the lifting frame 31 stops at the docking position, the passenger cabin door 301 of the passenger cabin 30 opens, and the personnel on board board the docking vessel 20 on the lifting frame 31 from the passenger cabin 30. Then the lifting frame 31 continues to descend. After the docking vessel 20 touches the water surface, the lifting frame 31 continues to descend rapidly. Under the combined effect of the buoyancy of the water and the rapid descent of the lifting frame 31, the docking vessel 20 and the lifting frame 31 achieve rapid separation, thus preventing the docking vessel 20 from being impacted or collided by the waves, ensuring the safety of the deployment process. The recovery process of the docking vessel 20 is simply the reverse operation of the deployment process, and will not be described in detail here.

[0041] like Figure 1As shown, the transfer frame 12 also includes a base frame 122 and diagonal braces 123. Lifting guide rails 121 are mounted on the base frame 122, and diagonal braces 123 are inclined between the lifting guide rails 121 and the base frame 122, so that the transfer frame 12 forms a triangular frame. Specifically, the base frame 122 is a rectangular frame, and lifting guide rails 121 are vertically installed on both sides of the base frame 122 along its length (the same as the length of the ship). Diagonal braces 123 are inclinedly installed between each lifting guide rail 121 and the base frame 122, so that the two sides of the transfer frame 12 along its length form a triangular structure, improving the structural strength and load-bearing capacity of the transfer frame 12.

[0042] Specifically, a set of traveling wheels 13 is installed at the bottom of the frame 122, and a slide rail 102 is provided inside the equipment compartment 10. The transfer drive component 11 drives the set of traveling wheels 13 to move along the slide rail 102 between the storage position and the limit position. Through the sliding engagement between the set of traveling wheels 13 and the slide rail 102, a guiding and limiting function is provided for the movement of the transfer frame 12 between the storage position and the limit position, thereby improving the movement accuracy and stability of the transfer frame 12.

[0043] like Figure 1 As shown, two sets of wheels 13 are spaced apart along the length of the bottom end of the frame 122. Two corresponding slide rails 102 are laid inside the equipment compartment 10. The wheels 13 on the same side of the bottom end of the frame 122 along the length of the frame roll into contact with the corresponding slide rail 102, further improving the movement accuracy and stability of the transfer frame 12. In other embodiments, three or more sets of wheels 13 may be spaced apart along the length of the bottom end of the frame 122. The number of slide rails 102 can be adjusted adaptively, and no specific limitation is made here.

[0044] Specifically, each traveling wheel assembly 13 includes a traveling wheel frame and multiple traveling wheels installed within the traveling wheel frame. The transfer drive component 11 is a rotary motor, which is small in size and easy to install and maintain. Each traveling wheel frame is equipped with a rotary motor, and the output end of the rotary motor is connected to one of the traveling wheels to drive the traveling wheel to roll along the slide rail 102.

[0045] Furthermore, such as Figure 1 and Figure 3As shown, a locking element 14 is also installed at the bottom of the base 122. The locking element 14 cooperates with the slide rail 102 to lock the transfer frame 12 in the extreme position or unlock the transfer frame 12. When the transfer frame 12 moves to the extreme position of the watertight door 101 extending out of the equipment compartment 10, the locking element 14 locks the transfer frame 12 in the extreme position, so that the lifting guide rail 121 and the transfer guide rail 2 are precisely connected, which improves the connection accuracy and stability of the lifting guide rail 121 and the transfer guide rail 2, so as to ensure that the lifting frame 31 moves smoothly between the lifting guide rail 121 and the transfer guide rail 2. In this embodiment, the locking element 14 is composed of a conical concave-convex component and a hydraulic cylinder pin. The locking element 14 reliably locks the transfer frame 12 in the extreme position through the hydraulic cylinder pin, completing the rapid connection between the lifting guide rail 121 and the transfer guide rail 2. The locking element 14 mentioned above is a mature product and can be obtained by purchasing. The specific structure and working principle of the locking element 14 will not be described in detail.

[0046] like Figure 2 and Figure 4 As shown, a fixed pulley 32 is provided at the top of the lifting frame 31, and a lifting rope 33 is wound around the fixed pulley 32. The lifting drive unit drives the lifting frame 31 to move up and down along the corresponding lifting guide rail 121 and the transfer guide rail 2 by winding and unwinding the lifting rope 33. The lifting rope 33 is suitable for long-distance power transmission, simplifies the structure of the lifting assembly 3, and facilitates the installation and maintenance of the lifting assembly 3. In this embodiment, the lifting rope 33 is a steel cable to ensure the lifting capacity of the lifting rope 33 and improve the safety of the lifting assembly 3. The lifting drive unit is a rotary motor, which is small in size and easy to install and maintain. The lifting drive unit realizes the rapid lifting and moving of the lifting frame 31 by winding and unwinding the lifting rope 33, which improves the lifting efficiency of the lifting frame 31, that is, the deployment and retrieval efficiency of the transfer vessel 20, thereby improving the operating efficiency of the vessel's transfer device.

[0047] like Figure 5 As shown, both the lifting guide rail 121 and the transfer guide rail 2 have track plates 21. The lifting frame 31 is equipped with a first guide wheel 34 and a second guide wheel 35. The first guide wheel 34 slides in cooperation with both sides of the track plate 21 in the width direction, and the second guide wheel 35 slides in cooperation with both sides of the track plate 21 in the thickness direction. Specifically, both the lifting guide rail 121 and the transfer guide rail 2 are I-beam rails, with one of the flanges of the I-beam rail serving as the track plate 21. The first guide wheel 34 slides on both sides of the track plate 21 in the width direction, and the second guide wheel 35 slides on both sides of the track plate 21 in the thickness direction, so that the track plate 21 provides guidance and limitation for the lifting frame 31 in two directions (i.e., the width direction and the thickness direction of the track plate 21), ensuring reliable rolling contact between the lifting frame 31 and the track plate 21, making the lifting frame 31 smoother and more stable during lifting.

[0048] Specifically, multiple first guide wheels 34 and second guide wheels 35 are spaced apart on both sides of the lifting frame 31 along the height direction, and the first guide wheels 34 and second guide wheels 35 are staggered, which further improves the stability of the rolling contact between the lifting frame 31 and the track plate 21.

[0049] like Figure 1 and Figure 2 As shown, the lifting frame 31 includes a main frame 311. At least two roller assemblies are spaced apart along the width of the main frame 311. Each roller assembly includes multiple roller modules 312 spaced apart along the length of the main frame 311. The roller modules 312 are inclined so that the at least two roller assemblies form a V-shaped frame that conforms to the bottom profile of the docking vessel 20. By configuring the at least two roller assemblies into a V-shaped frame that conforms to the bottom profile of the docking vessel 20, the roller assemblies better support the docking vessel 20, achieving stable support for the docking vessel 20 and preventing swaying of the docking vessel 20 during lifting and lowering with the lifting frame 31, thus improving the stability and safety of the docking vessel 20.

[0050] Specifically, multiple V-shaped beams are installed along the length of the bottom of the main frame 311. Two roller assemblies are symmetrically installed on each V-shaped beam, so that two roller assemblies are spaced apart along the width of the main frame 311, and the two roller assemblies form a V-shaped frame that matches the bottom profile of the docking vessel 20. Of course, four, six, or other numbers of roller assemblies can also be symmetrically installed on each V-shaped beam, as long as they can form a V-shaped frame that matches the bottom profile of the docking vessel 20.

[0051] Furthermore, such as Figure 6 As shown, the roller module 312 includes a roller frame 3121, a roller shaft 3122, and rollers 3123. The roller frame 3121 is mounted on the main frame 311. Rollers 3123 are rotatably mounted at both ends of the roller shaft 3122. The roller shaft 3122 is inclined and movably mounted on the roller frame 3121 so that the V-angle of the V-shaped frame is adjustable. The roller frame 3121 extends along the length of the main frame 311, and the roller shaft 3122 is V-shaped and extends along the width of the main frame 311. The middle position of the roller shaft 3122 is movably mounted on the roller frame 3121 via a pivot, so that the roller shaft 3122 can rotate within a certain angle range relative to the roller frame 3121. When the docking boat 20 is located on the main frame 311, the roller shaft 3122 rotates and changes its tilt angle under the pressure of the docking boat 20, so that the V-angle of the V-shaped frame can be adaptively adjusted according to the different bottom contours of the docking boat 20, so as to stably support the docking boat 20 and improve the versatility of the lifting frame 31.

[0052] Specifically, the docking vessel 20 can move into or out of the lifting frame 31 along the length of the main frame 311, and the docking vessel 20 makes rolling contact with the rollers 3123, reducing the friction between the docking vessel 20 and the lifting frame 31 and improving the deployment and retrieval efficiency of the docking vessel 20. The rollers 3123 are rubber wheels, which have good elasticity and can prevent hard contact between the rollers 3123 and the docking vessel 20, thus improving the protection of the docking vessel 20. In this embodiment, the roller frame 3121 is equipped with multiple roller shafts 3122 at intervals along the length of the main frame 311, and each roller shaft 3122 has rollers 3123 rotatably mounted at both ends, thereby increasing the number of rollers 3123 in each roller module 312, thereby increasing the contact area between the roller module 312 and the docking vessel 20, and improving the support strength and stability of the roller module 312 for the docking vessel 20.

[0053] like Figure 2 As shown, a guardrail 313 is provided on the side of the main frame 311 away from the lifting guide rail 121. The main frame 311 and the guardrail 313 form a U-shaped channel to accommodate the barge 20. The guardrail 313 protects the barge 20, preventing it from tilting excessively or tipping over, thus improving the stability of the lifting frame 31 and the barge 20 during lifting and moving, and ensuring the safety of the vessel transfer device.

[0054] It should be noted that the guardrail 313 is a grating, and each grating can be fitted with a wave deflector with evenly distributed permeable holes to prevent the impact and collision of wind and waves on the barge 20 supported on the lifting frame 31. This prevents the barge 20 from swaying significantly during deployment and recovery, further improving the safety of the vessel's transfer device. Simultaneously, the guardrail 313 is inclined outwards at both ends along the length of the main frame 311, so that the U-shaped channel formed by the main frame 311 and the guardrail 313 has a guide opening for the barge 20 to enter and exit, ensuring that the barge 20 quickly enters the lifting frame 31 under the guidance of the guide opening.

[0055] Furthermore, such as Figure 1 and Figure 2 As shown, a buffer pad 314 is installed on the inner wall of the guardrail 313. By setting the buffer pad 314, a hard collision between the barge 20 and the guardrail 313 is avoided, improving the protection of the barge 20 and the safety of the ship's transfer device. In this embodiment, the buffer pad 314 can be a buffer airbag or a rubber tire commonly used in ports and docks, etc., and is not specifically limited here.

[0056] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
