Description

Technical Field

[0001] This application belongs to the field of transport ship deck technology, and particularly relates to an extended deck for a deck transport ship. Background Technology

[0002] A transport ship deck is a horizontal structural platform on a ship used to carry cargo, equipment, and personnel. It is an important component of a ship and is usually made of materials such as steel plates. It has a certain strength and rigidity and can withstand the weight of the cargo and various forces that the ship experiences during navigation. Generally, extended decks are used to increase the cargo area of ​​a transport ship or to optimize the ship's berthing stability.

[0003] The existing utility model with authorization announcement number CN222611357U discloses a docking support for a deck transport ship. Through the arrangement of an installation plate, a movable plate, a support plate, and a buffer component, the hull contacts the support plate. Simultaneously, the support plate pushes the movable plate, which is located within the installation plate, to descend. The movable plate also compresses the buffer component within the installation plate, preventing the hull from directly contacting the shore. This reduces damage to the hull's sidewalls, minimizes hull wear, and improves navigation safety. Through the arrangement of an installation shaft, gears, and shock-absorbing components, the hull contacts the support plate on one side and moves towards the shore. As the hull moves towards the shore, it pushes the movable plate and installation plate to one side, causing them to rotate. The installation shaft rotates synchronously with the installation plate, and the gears mesh with the shock-absorbing components, enhancing the absorption of buffer pressure when the hull docks and reducing contact between the hull and the shore.

[0004] While the above technical solutions can reduce damage to the hull sidewalls, reduce hull wear, and improve navigation safety, they also have too many shafts and gear structures. These structures are prone to damage to the transmission structure when subjected to large compressive or collision forces. The lack of a high-safety buffer structure means that the extension structure will suffer damage to the transmission structure when subjected to large compressive or collision forces, which will greatly reduce the safety and service life of the extension structure.

[0005] To address this issue, we propose an extended deck for deck transport ships. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that the lack of a high-safety buffer structure leads to damage to the transmission structure when the extension structure encounters large compressive or collision forces, which greatly reduces the safety and service life of the extension structure. Therefore, this invention proposes an extension deck for deck transport ships.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An extended deck for a deck transport vessel includes a storage shell, an extension plate slidably connected inside the storage shell, a bracket fixedly connected to the upper surface of the storage shell, a hydraulic rod fixedly connected to the inner wall of the bracket, a button controller fixedly connected to the upper surface of the bracket, a servo motor fixedly connected to the inner wall of the storage shell, a threaded rod fixedly connected to the output end of the servo motor, a connecting plate fixedly connected to the telescopic end of the hydraulic rod, two limiting blocks fixedly connected to the bottom surface of the connecting plate, two limiting grooves formed in the inner bottom wall of the storage shell, two guide rods slidably connected inside the extension plate, a buffer plate provided on the outer side of the extension plate, and two dampers fixedly connected to the inner wall of the extension plate, each damper having a return spring sleeved on its outer surface.

[0009] Preferably, the outer surface of the threaded rod is threadedly connected to the inner wall of the extension plate, the bottom surface of the connecting plate is in contact with the upper surface of the housing, the outer surface of each limiting block is slidably connected to the inside of the housing and the inside of the extension plate, the inner wall of each limiting groove is in contact with the outer surface of the limiting block, the end of each guide rod away from the extension plate is fixedly connected to the back of the buffer plate, the telescopic end of each damper is fixedly connected to the end of the guide rod near the extension plate, the two ends of each return spring are in contact with the inner wall of the extension plate and the end of the guide rod near the extension plate, and mounting plates are fixedly connected to both sides of the housing, with several identical mounting holes opened on the upper surface of each mounting plate.

[0010] Preferably, the upper surface of the storage shell is fixedly connected to two connecting posts, and each connecting post is fixedly connected to a hook at its top.

[0011] Preferably, both sides of the extension plate are fixedly connected to limit sliders, and the outer surface of each limit slider is slidably connected to the inside of the storage shell.

[0012] Preferably, a coupling is fixedly connected to the outer surface of the output end of the servo motor, and the inner wall of the coupling is fixedly connected to the outer surface of the threaded rod.

[0013] Preferably, a buffer pad is fixedly connected to the front side of the buffer plate, and a plurality of identical buffer protrusions are fixedly connected to the front side of the buffer pad.

[0014] In summary, the technical effects and advantages of this application are as follows:

[0015] Through the coordinated operation of the housing, extension plate, bracket, hydraulic rod, button controller, connecting plate, limit block, servo motor, threaded rod, limit groove, guide rod, damper, return spring, and buffer plate, the button controller can control the servo motor to drive the threaded rod to rotate, thereby allowing the extension plate, which is threadedly connected to the threaded rod, to slide back and forth within the housing. This enables the extension plate to extend or retract relative to the housing. After the extension plate extends out of the housing, the button controller automatically controls the hydraulic rod to extend, allowing the limit block under the connecting plate to pass through the housing and extension plate and insert into the limit groove, thus fixing the position of the extension plate relative to the housing. The extension plate is not easily damaged by external forces. The damper and return spring provide good buffering between the extension plate and the guide rod, greatly improving the safety of the overall buffer structure. This avoids the problem of reduced safety and service life of the extension structure due to damage to the transmission structure when the extension structure encounters large compressive or impact forces, which is caused by the lack of a high-safety buffer structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4An extended deck for a deck transport ship includes a housing 1, an extension plate 2 slidably connected inside the housing 1, a bracket 3 fixedly connected to the upper surface of the housing 1, a hydraulic rod 4 fixedly connected to the inner wall of the bracket 3, and mounting plates 15 fixedly connected to both sides of the housing 1. Each mounting plate 15 has several identical mounting holes 16 on its upper surface. By setting the mounting holes 16, the mounting plates 15 can be fixedly installed on the edge of the fixed deck of the transport ship or inside the side of the transport ship with the help of external bolts, thereby facilitating the fixation of the entire extended deck structure.

[0023] A button controller 5 is fixedly connected to the upper surface of the bracket 3. The button controller 5 can be an MCU or an Arduino series, which is small in size, low in cost and low in power consumption, and suitable for miniaturization and embedded applications. It can control multiple components through programming. It can be connected to the control terminal of each electrical component through digital output pins and control the power of each component through analog output pins. Specific control logic and timing can be implemented by writing code. A servo motor 8 is fixedly connected to the inner wall of the storage shell 1. The servo motor 8 has a built-in angle encoder, so the button controller 5 can accurately control the number of rotations and rotation angle of the servo motor 8. A threaded rod 9 is fixedly connected to the output end of the servo motor 8. The outer surface of the threaded rod 9 is threadedly connected to the inner wall of the extension plate 2. Two connecting posts 17 are fixedly connected to the upper surface of the storage shell 1. A hook 18 is fixedly connected to the top of each connecting post 17. By setting the connecting posts 17, the storage shell 1 and the hook 18 can be connected. By setting the hook 18, the entire structure can be lifted and transported flexibly.

[0024] A connecting plate 6 is fixedly connected to the telescopic end of the hydraulic rod 4. The bottom surface of the connecting plate 6 is in contact with the upper surface of the storage shell 1. Two limiting blocks 7 are fixedly connected to the bottom surface of the connecting plate 6. The outer surface of each limiting block 7 is slidably connected to the interior of the storage shell 1 and the interior of the extension plate 2, respectively. Two limiting grooves 10 are opened in the inner bottom wall of the storage shell 1. The inner wall of each limiting groove 10 is in contact with the outer surface of the limiting block 7. Limiting sliders 22 are fixedly connected to both sides of the extension plate 2. The outer surface of each limiting slider 22 is slidably connected to the interior of the storage shell 1. By setting the limiting sliders 22, the extension plate 2 can slide back and forth inside the storage shell 1, thereby increasing the orientation and stability of the reciprocating sliding of the extension plate 2 inside the storage shell 1.

[0025] The extension plate 2 has two guide rods 11 slidingly connected inside. A buffer plate 14 is provided on the outer side of the extension plate 2. The end of each guide rod 11 away from the extension plate 2 is fixedly connected to the back of the buffer plate 14. A coupling 21 is fixedly connected to the outer surface of the output end of the servo motor 8. The inner wall of the coupling 21 is fixedly connected to the outer surface of the threaded rod 9. By setting the coupling 21, the connection between the output end of the servo motor 8 and the threaded rod 9 can be strengthened, thereby increasing the rotational stability of the threaded rod 9.

[0026] Two dampers 12 are fixedly connected to the inner wall of the extension plate 2. The telescopic end of each damper 12 is fixedly connected to the end of the guide rod 11 near the extension plate 2. A return spring 13 is sleeved on the outer surface of each damper 12. The two ends of each return spring 13 are in contact with the inner wall of the extension plate 2 and the end of the guide rod 11 near the extension plate 2, respectively. A buffer pad 19 is fixedly connected to the front of the buffer plate 14. Several identical buffer cams 20 are fixedly connected to the front of the buffer pad 19. By setting the buffer cams 20, the buffering effect of the front of the buffer pad 19 can be increased. By setting the buffer pad 19 and the buffer cams 20, the buffering effect of the front of the buffer plate 14 can be increased together.

[0027] The working principle of this utility model is as follows: In use, the mounting plate 15 is fixed to the edge of the fixed deck of the transport ship or fixedly loaded inside the side of the transport ship using external bolts and other positioning column structures in conjunction with the mounting holes 16. Then, the working state of the servo motor 8 and hydraulic rod 4 can be controlled directly by touching the button controller 5 or using the remote button controller 5. When the extension plate 2 and buffer plate 14 structure are not needed, the button controller 5 controls the hydraulic rod 4 to fully retract, and the limit block 7 does not limit the extension plate 2. Then, the button controller 5 automatically controls the servo motor 8 to drive the threaded rod 9 to rotate, and the extension plate 2 is then completely stored in the housing 1. When the extension plate 2 and buffer plate 14 structure are needed to assist the docking of the entire hull, the operation causes the button controller 5 to control the servo motor 8 to drive the threaded rod 9 to rotate, and the extension plate 2, which is threadedly connected to the threaded rod 9, is then stored in the housing 1. The extension plate 2 slides within the housing 1, allowing it to extend or retract relative to the housing 1. After the extension plate 2 extends out of the housing 1, the button controller 5 automatically controls the hydraulic rod 4 to extend, causing the limiting block 7 under the connecting plate 6 to pass through the housing 1 and the extension plate 2 and insert into the limiting groove 10, thereby fixing the position of the extension plate 2 relative to the housing 1. The extension plate 2 is not easily damaged by external forces. When the buffer plate 14 encounters external pressure or collision, the damper 12 and the return spring 13 form a good buffer between the extension plate 2 and the guide rod 11, thereby greatly improving the safety of the overall buffer structure. The design of the entire extension deck for deck transport ships effectively solves the problem that the lack of a high-safety buffer structure leads to damage to the transmission structure when the extension structure encounters large compressive or collision forces, resulting in a significant reduction in the safety and service life of the extension structure.
