Description

Technical Field

[0001] This invention relates to the field of research vessel technology, and in particular to a cable deployment and retrieval system and a vessel. Background Technology

[0002] A research vessel, also known as a scientific research vessel, is an engineering vessel specifically designed to perform multidisciplinary surveys in marine hydrology, geology, meteorology, biology, and other fields. During scientific research operations, the deployment and retrieval of research equipment (such as sample containers and hydrographic instruments) is a crucial step. Most existing research vessels are equipped with winches, cables, and rigging systems to facilitate the deployment and retrieval of research equipment in seawater, thereby completing the research operation.

[0003] To meet the requirements for surveying different locations around the hull, the hull is generally equipped with multiple deployment and recovery positions, each with its own independent deployment and recovery device. This results in redundant configuration of devices such as winches and cables, leading to equipment redundancy, occupation of deck space, and increased ship load. This not only increases the initial investment cost but also raises the subsequent maintenance costs.

[0004] Therefore, there is an urgent need to design a take-up and release system to solve the above-mentioned problems in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a cable release and take-up system and a vessel, which has a simple structure, flexible operation, and can effectively reduce equipment redundancy and space occupation of the hull.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A cable retrieval system, used for lowering or retrieving heavy objects from the hull, including:

[0008] A winch is installed on the hull.

[0009] Cable;

[0010] Multiple support brackets are installed at different locations on the hull deck, and each support bracket is equipped with a first pulley;

[0011] A reversing pulley mechanism, comprising a second pulley and a pulley frame, wherein the pulley frame is rotatably connected to the deck, and the second pulley is rotatably disposed on the pulley frame;

[0012] One end of the cable is mounted on the winch, and the other end of the cable is wound around the first pulley via the second pulley. The cable is used to connect to the heavy object, and the rotation of the pulley frame can drive the cable to face the support frame.

[0013] Preferably, the rotation axis of the first pulley and the rotation axis of the second pulley are both perpendicular to the height direction of the support, and the rotation axis of the pulley frame is parallel to the height direction of the support.

[0014] Preferably, the reversing pulley mechanism further includes a mounting frame, which is fixedly mounted on the deck of the hull. A central shaft is provided on the top of the mounting frame. The pulley frame includes a sleeve and a frame plate fixedly connected to the sleeve. The second pulley is rotatably connected to the frame plate via a pin. The sleeve is sleeved on the central shaft and is rotatable relative to the central shaft.

[0015] Preferably, the mounting bracket includes an adjustable-length upright, which is fixedly mounted on the deck, and the central axis is located at the top of the upright.

[0016] Preferably, the reversing pulley mechanism further includes a locking member disposed on the upright. When the pulley frame rotates to the position where the cable is directly opposite the support frame, the locking member can be limited and abut against the pulley frame in the rotation direction of the pulley frame.

[0017] Preferably, the pulley frame further includes a limiting hole plate, which is connected to the sleeve. The limiting hole plate has multiple slots along the circumference of the sleeve, and the locking member can be inserted into the slots for limiting.

[0018] Preferably, the reversing pulley mechanism further includes a driving member, a first gear is coaxially arranged on the sleeve, and a second gear that meshes with the first gear is arranged on the output end of the driving member, and the driving member can drive the second gear to rotate.

[0019] The vessel includes a hull and the aforementioned cable winding and unwinding system, wherein the winch is installed on the hull and multiple supports are fixedly installed at different locations on the deck.

[0020] Preferably, the height of the support bracket is adjustable.

[0021] Preferably, the hull is provided with a height-adjustable mounting bracket, and the pulley bracket is rotatably mounted on the mounting bracket.

[0022] The beneficial effects of this invention are as follows:

[0023] The cable lowering and lowering system provided by this invention is used for lowering or retrieving heavy objects from or from a ship. The system includes a winch, a cable, multiple support frames, and a reversing pulley mechanism. Since multiple support frames are installed on the deck at different locations, the cable is wound around a first pulley via a second pulley, and the winch is connected to the heavy object via the cable. Therefore, the winch is used to lower and retrieve the heavy object from the ship, enabling normal scientific research operations on the research vessel. The second pulley is rotatably mounted on a pulley frame, and the cable is wound around the first pulley via the second pulley. The system features a pulley system. Because the pulley frame can rotate, and when the pulley frame rotates, it can drive the cable on the second pulley to align with the support frame. Therefore, by rotating the pulley frame, the cable can be aligned with the support frames at different locations on the deck, thereby enabling the lowering and retrieval of heavy objects at different locations around the hull. Furthermore, this cable lowering and retrieval system only requires one winch and one cable. By using a reversing pulley mechanism, it can flexibly lower and retrieve heavy objects at multiple locations. The system is simple in structure, flexible in operation, and significantly improves the deployment efficiency of the ship while reducing equipment redundancy and space occupation.

[0024] The vessel provided by this invention includes a hull and the aforementioned cable release and retrieval system. The winch is installed on the hull, and multiple support brackets are fixedly installed on the deck. This vessel can lower and retrieve heavy objects at different locations on the hull. It has a simple structure and flexible operation, which can effectively reduce equipment redundancy and hull space occupation, thereby greatly reducing system costs and maintenance difficulty, and has broad application prospects.

[0037] like Figure 1As shown, the present invention provides a cable retrieval system for lowering or retrieving heavy objects from a ship hull 100. The cable retrieval system includes a winch 1, a cable 2, multiple support frames 3, and a reversing pulley mechanism 4. The winch 1 is located on the ship hull 100, and the multiple support frames 3 are located at different positions on the deck of the ship hull 100. A first pulley 31 is provided on each support frame 3. The reversing pulley mechanism 4 includes a second pulley 42 and a pulley frame 41. The pulley frame 41 is rotatably connected to the deck, and the second pulley 42 is rotatably mounted on the pulley frame 41. One end of the cable 2 is located on the winch 1, and the other end of the cable 2 is wound around the first pulley 31 via the second pulley 42. The cable 2 is used to connect to the heavy object. The rotation of the pulley frame 41 can drive the cable 2 to face the support frame 3.

[0038] In this embodiment, since multiple support brackets 3 are installed on the deck of the hull 100 at different locations on the deck, the cable 2 is wound around the first pulley 31 via the second pulley 42, and the winch 1 is connected to the heavy object via the cable 2. Therefore, the heavy object is lowered and retrieved from the hull 100 by the winch 1 to realize the normal scientific research operation of the research vessel; the second pulley 42 is rotatably mounted on the pulley frame 41, and the cable 2 is wound around the first pulley 31 via the second pulley 42. Since the pulley frame 41 can rotate, and the pulley frame... When 41 rotates, it can drive the cable 2 on the second pulley 42 to be aligned with the support 3. Therefore, by rotating the pulley frame 41, the cable 2 can be aligned with the support 3 at different positions on the deck, thereby realizing the lowering and retrieval of heavy objects at different positions around the hull 100. Moreover, this cable retrieval system only has one winch 1 and one cable 2. The reversing pulley mechanism 4 can realize the flexible retrieval of heavy objects at multiple positions. The structure is simple and the operation is flexible, which significantly improves the deployment efficiency of the ship and reduces equipment redundancy and space occupation.

[0039] Specifically, the vessel is a research vessel, and the heavy object is the research equipment on the vessel (such as sampling boxes, hydrological instruments, etc.). The support frame 3 is used to lower the research equipment from the hull 100 into the surrounding seawater, and also to pull the research equipment in the seawater onto the hull 100. The heavy object can also be cargo transported by the vessel. The support frame 3 is used to lower the cargo from the hull 100 onto the dock, and also to pull the cargo from the dock onto the hull 100. The specific form and structure of the support frame 3 can be set according to the actual situation, as long as it can provide a fixed point for the first pulley 31 to ensure that the cable 2 can be smoothly loaded and unloaded.

[0040] In this embodiment, the vessel is a research vessel equipped with a moon pool, such as... Figure 1As shown, four support frames 3 are provided, located on the port side, starboard side, stern, and above the moon pool of the hull 100. The support frames 3 on the port side, starboard side, and stern of the hull 100 are gantry structures commonly used in this field, with the first pulley 31 rotatably mounted on the top of the gantry. The support frame 3 above the moon pool is a small support structure fixed to the top of the cabin, with the first pulley 31 rotatably mounted on the bottom of the support structure. When it is necessary to lower scientific research equipment to the sea area on the port side, the staff rotates the pulley frame 41 to align the length direction of the cable 2 with the support frame 3 on the port side, and then pulls the cable 2 to... The equipment can be connected to the first pulley 31 of the port side support 3 after passing over the first pulley 31. If the scientific research equipment needs to be deployed in the sea area on the starboard side, the pulley frame 41 needs to be rotated so that the length direction of the cable 2 on the second pulley 42 is aligned with the support 3 on the starboard side, and then the cable 2 is pulled to the first pulley 31 of the support 3 on the starboard side. If the scientific research equipment needs to be deployed in the sea area of ​​the moon pool, the pulley frame 41 needs to be rotated so that the length direction of the cable 2 on the second pulley 42 is aligned with the first pulley 31 above the moon pool, and then the cable 2 is pulled to the first pulley 31 above the moon pool.

[0041] Specifically, the rotation axis of the first pulley 31 and the rotation axis of the second pulley 42 are both perpendicular to the height direction of the support 3, and the rotation axis of the pulley frame 41 is parallel to the height direction of the support 3, so as to ensure that the cable 2 can smoothly load and unload heavy objects vertically, and at the same time ensure that the pulley frame 41 can rotate smoothly to align with different supports 3.

[0042] In this embodiment, the reversing pulley mechanism 4 also includes a mounting frame, which is fixedly mounted on the deck of the hull 100. A central shaft is provided on the top of the mounting frame. The pulley frame 41 includes a sleeve and a frame plate fixedly connected to the sleeve. The second pulley 42 is rotatably connected to the frame plate via a pin. The sleeve is fitted onto the central shaft and can rotate relative to the central shaft. Specifically, the central shaft is a smooth cylindrical structure. The sleeve is fitted onto the central shaft and can therefore rotate relative to the central shaft under the action of external force. The second pulley 42 is rotatably connected to the frame plates on both sides via pins. The frame plates are welded to the sleeve. When the sleeve rotates relative to the central shaft, it can drive the second pulley 42 to rotate, thereby switching the guiding direction of the cable 2. Specifically, the mounting frame includes an adjustable-length upright, which is fixedly mounted on the deck, with a central axis located at the top of the upright. Because the length of the upright is adjustable, the height of the reversing pulley mechanism 4 at the top of the upright can be adjusted, making the cable retrieval system suitable for more scenarios and improving its applicability.

[0043] To improve the stability of the cable winding and unwinding system during use, the reversing pulley mechanism 4 also includes a locking element. The locking element is installed on the upright. When the pulley frame 41 rotates to the point where the cable 2 is directly opposite the support 3, the locking element can be limited and abutted against the pulley frame 41 in the direction of rotation of the pulley frame 41. In this embodiment, the pulley frame 41 also includes a limiting hole plate connected to the sleeve. The limiting hole plate has multiple slots along the circumference of the sleeve, and the locking member can be inserted into the slot to fix the pulley frame 41. Specifically, the locking member is a pin, and the upright has a through hole. The limiting hole plate is a ring structure, which is sleeved on the sleeve and welded to the sleeve. The limiting hole plate is located below the frame plate and the second pulley 42. When the sleeve rotates relative to the central axis, the limiting hole plate also rotates. The limiting hole plate has slots corresponding to the directions of each support 3. Multiple slots are arranged along the circumference of the sleeve. When the pulley frame 41 rotates to the designated direction, the worker passes the locking member vertically through the slot and the through hole in sequence. The head of the pin is blocked on the limiting hole plate, thereby fixing the pulley frame 41 and preventing the pulley frame 41 from continuing to rotate, so as to ensure the stability and reliability of the cable 2 when loading and unloading heavy objects.

[0044] The reversing pulley mechanism 4 can also be hoisted inside the cabin; specifically, a central shaft is installed on the top of the cabin, and the pulley frame 41 is sleeved on the central shaft through a sleeve, so it can rotate relative to the central shaft under the action of external force; the second pulley 42 is rotatably connected to the frame plates on both sides through a pin, and the frame plates are welded to the sleeve, so when the sleeve rotates relative to the central shaft, it can drive the second pulley 42 to rotate, thereby switching the guiding direction of the cable 2; the reversing pulley mechanism 4 also includes a locking element, and the pulley frame 41 also includes a limiting hole plate, which is a ring structure and is sleeved on the sleeve and welded to the sleeve, and the limiting hole... The plate is positioned above the frame plate and the second pulley 42. When the sleeve rotates relative to the central axis, the limiting hole plate also rotates accordingly. The limiting hole plate has slots corresponding to the directions of each support frame 3, and multiple slots are arranged along the circumference of the sleeve. A fixing plate is provided on the top of the compartment, and a through hole is provided on the fixing plate. When the pulley frame 41 rotates to the designated direction, the operator will pass the locking piece vertically through the through hole and the slot in sequence. The head of the pin will be stuck on the fixing plate, thereby fixing the pulley frame 41 and preventing the pulley frame 41 from continuing to rotate, so as to ensure the stability and reliability of the cable 2 when loading and unloading heavy objects.

[0045] To improve the automation and ease of use of the cable winding and unwinding system, the reversing pulley mechanism 4 also includes a drive component 43. A first gear is coaxially mounted on the sleeve, and a second gear meshing with the first gear is mounted on the output end of the drive component 43. The drive component 43 can drive the second gear to rotate. Specifically, the drive component 43 is a motor, and the output shaft of the drive component 43 is connected to the sleeve through the meshing of the first and second gears. Therefore, the operator can control the rotation of the pulley frame 41 through the drive component 43, achieving the switching of the cable 2's guiding direction without manual rotation. In another embodiment, as... Figure 2 As shown, the top of the mounting frame is provided with a top sleeve and a bottom sleeve. The pulley frame 41 includes a vertically arranged rotating shaft and a frame plate fixedly connected to the rotating shaft. The top and bottom ends of the rotating shaft are respectively inserted into the top sleeve and the bottom sleeve. The frame plate is connected to the part between the top and bottom ends of the rotating shaft, so it will not interfere with the top sleeve and the bottom sleeve. The drive unit 43 is set on the mounting frame and located above the pulley frame 41. The output shaft of the drive unit 43 is directly connected to the rotating shaft of the pulley frame 41. Therefore, the operator can drive the rotating shaft to rotate relative to the top sleeve and the bottom sleeve through the drive unit 43, thereby realizing the rotation of the pulley frame 41 to switch the guiding direction of the cable 2.

[0046] This application also provides a vessel, such as Figure 1 As shown, the vessel includes a hull 100 and the aforementioned cable deployment and retrieval system. A winch 1 is installed on the hull 100, and multiple support brackets 3 are fixedly installed at different locations on the deck. In this embodiment, the vessel can lower and retrieve heavy objects at different locations on the hull 100. It features a simple structure, flexible operation, and effectively reduces equipment redundancy and space occupation on the hull 100, thereby significantly reducing system costs and maintenance difficulty, and has broad application prospects.

[0047] In this embodiment, the vessel is a research vessel, the heavy object is the research equipment on the research vessel (such as a sampling box, hydrological measuring instrument, etc.), and the support frame 3 is used to lower the research equipment from the hull 100 into the surrounding seawater, and also to pull the research equipment in the seawater onto the hull 100.

[0048] Specifically, such as Figure 1 As shown, a height-adjustable mounting frame is provided on the hull 100, and the pulley frame 41 is rotatably mounted on the mounting frame. Since the height of the mounting frame is adjustable, the staff can adjust the height of the reversing pulley mechanism 4 at the top of the pole, so that the cable winding and unwinding system can be applied to more scenarios, thus improving the applicability of the cable winding and unwinding system. In order to further improve the practicality of the cable winding and unwinding system, the support frame 3 is a height-adjustable gantry structure.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
