Description

Technical Field

[0001] This utility model relates to the field of cargo ship technology, and in particular to an anti-jump device, a cargo hold structure, and a ship. Background Technology

[0002] Cargo ships typically have cargo holds and hatch covers that are relatively large compared to the hull. There are various types of hatch covers, among which the lift-off hatch cover is the most widely used due to its simple structure and low cost. Lift-off hatch covers are sealed to the hatch opening using rubber strips to ensure cargo safety. Since there are no fixed connections between the hatch cover and the cargo hold structure, the hatch cover can shift and bounce during operation due to the ship's movement and its own weight. To prevent damage to the seal between the hatch cover and the hatch opening, an effective anti-bouncing device is needed to control the hatch cover's displacement.

[0003] Traditional lift-off cargo hatch covers typically involve installing eyeplates on both the hatch cover and the hatch side panel of the cargo hold structure. These eyeplates are then locked in place using a pin-locking method to prevent the hatch cover from bouncing off. However, this method is cumbersome and requires welding the eyeplates and other structures onto both the hatch cover and the hatch side panel. If adjustments are needed later, the eyeplates must be removed, which can easily damage both the hatch cover and the cargo hold structure.

[0004] Therefore, there is an urgent need for an anti-jump device, cargo hold structure, and ship to solve the above problems. Utility Model Content

[0045] Figure 1This diagram shows a partial structural schematic of the cargo hold structure provided in an embodiment of the present invention; Figure 2 This diagram illustrates the anti-jump device provided in an embodiment of the present invention in the unlocked and locked positions. (Refer to...) Figure 1 and Figure 2 This embodiment provides an anti-jump device, a cargo hold structure, and a ship.

[0046] The cargo hold structure provided in this embodiment includes a cargo hold space, a hatch side panel 10, a column 20, and a hatch cover 30. It also includes an anti-jump device provided in this embodiment. The hatch side panel 10 is formed at the opening of the cargo hold space, the column 20 is disposed on the hatch side panel 10, and the hatch cover 30 can cover the opening of the cargo hold space and abut against the top of the hatch side panel 10.

[0047] The ship provided in this embodiment is equipped with the aforementioned cargo hold structure to facilitate cargo storage.

[0048] Figure 3 This diagram shows the installation of the anti-jump device provided in this embodiment of the invention on a column; Figure 4 An exploded view of the anti-jump device provided in an embodiment of this utility model is shown. (Refer to...) Figures 1-4 The anti-jump device provided in this embodiment includes a mounting base 100, an anti-jump mechanism 200, and a locking mechanism 300.

[0049] Specifically, the mounting base 100 is disposed on the column 20 of the cargo hold structure, which is located outside the cargo hold space of the cargo hold structure. The mounting base 100 provides a mounting position for the anti-jump mechanism 200. The anti-jump mechanism 200 is rotatably connected to the mounting base 100 and can rotate between an unlocked position and a locked position. When the anti-jump mechanism 200 is in the locked position, it presses against the hatch cover 30 of the cargo hold structure, pressing the hatch cover 30 against the hatch side enclosure 10 of the cargo hold structure and sealing the opening of the cargo hold space. By rotating the anti-jump mechanism 200, the locking and unlocking of the hatch cover 30 can be switched, thereby simplifying the locking operation of the hatch cover 30. The locking mechanism 300 is detachably disposed on the mounting base 100 and can lock the anti-jump mechanism 200 in the locked position. The locking mechanism 300 ensures the reliability of the anti-jump mechanism 200 in resisting the hatch cover 30, thereby strengthening the anti-jump strength of the anti-jump device on the hatch cover 30.

[0050] Continue to refer to Figure 3 and Figure 4The mounting base 100 includes a frame body 110, which is fixedly disposed on the side of the column 20. The anti-jump device also includes a rotating shaft 400, which is mounted in the frame body 110 and parallel to the extending direction of the column 20. The anti-jump mechanism 200 is connected to the rotating shaft 400 and can rotate about the axis of the rotating shaft 400 to switch between an unlocked position and a locked position.

[0051] More specifically, the anti-jump mechanism 200 includes an anti-jump main body 210 and a pressure-resistant anti-jump part 220. The anti-jump main body 210 is rotatably connected to the mounting base 100. The pressure-resistant anti-jump part 220 is disposed on the side of the anti-jump main body 210 facing the hatch cover 30, and the side of the pressure-resistant anti-jump part 220 opposite to the anti-jump main body 210 forms a pressure-resistant surface that can press against the hatch cover 30. The area of ​​the pressure-resistant surface is larger than the area of ​​the bottom of the anti-jump main body 210, which increases the contact area between the anti-jump mechanism 200 and the hatch cover 30, thereby ensuring the pressure-resistant effect.

[0052] More specifically, the anti-jump mechanism 200 further includes a first rotating connection portion 230, which is a hollow cylindrical structure and is disposed on one side of the anti-jump main body portion 210. The first rotating connection portion 230 is rotatably sleeved on the outside of the rotating shaft 400 around the axis of the rotating shaft 400.

[0053] Preferably, the anti-jump mechanism 200 further includes a second rotating connection portion 240, which is a hollow cylindrical structure and fixed to one side of the anti-jump part 220. It is spaced apart from the first rotating connection portion 230. The mounting base 100 also includes a limiting plate 120, which is disposed in the frame body 110, and the rotating shaft 400 passes through the limiting plate 120. The second rotating connection portion 240 is located between the bottom of the frame body 110 and the limiting plate 120, and is rotatably sleeved around the axis of the rotating shaft 400. Through the aforementioned second rotating connection portion 240, the reliability of the rotating connection between the anti-jump mechanism 200 and the rotating shaft 400 can be further improved based on the first rotating connection portion 230. By means of the limiting plate 120, the second rotating connection part 240 can be positioned at the bottom of the frame body 110, preventing the anti-jump mechanism 200 from moving in the extension direction of the rotating shaft 400, thereby improving the stability of the anti-jump mechanism 200 relative to the frame body 110.

[0054] Preferably, the anti-jump mechanism 200 further includes an operating handle 250, which is fixedly connected to one side of the anti-jump main body 210 and is disposed opposite to the first rotating connection part 230. The operating handle 250 provides a convenient gripping position for the operator, and the user can rotate the anti-jump main body 210 by means of the operating handle 250.

[0055] Continue to refer to Figures 1-4 The mounting base 100 also includes a positioning part 130, which has a plate-like structure and is fixed to the top of the frame body 110. The positioning part 130 can abut against the column 20 to improve the installation stability and reliability of the frame body 110 on the column 20.

[0056] Specifically, the locking mechanism 300 includes a locking main body 310 and a locking action part 320. The locking main body 310 is detachably connected to the positioning part 130, and the locking action part 320 is connected to one side of the locking main body 310 and can abut against the anti-jump main body 210 to position the anti-jump mechanism 200 in the locked position. The locking action part 320 ensures the stability of the anti-jump mechanism 200 in the locked position.

[0057] More specifically, the locking mechanism 300 also includes a positioning pin (not shown). The locking body 310 has a first insertion hole 311, and the positioning part 130 has a second connection hole 131. The positioning pin can be inserted into the first insertion hole 311 and the second connection hole 131. Through the above arrangement, the locking mechanism 300 can be detachably connected to the mounting base 100.

[0058] More specifically, the locking mechanism 300 also includes a latching part 330. The latching part 330 is disposed on the locking main body 310, and is located on opposite sides of the locking main body 310, respectively, as is the locking action part 320. A latching groove 331 can be formed between the latching part 330 and the locking main body 310. The positioning part 130 can be latched into the latching groove 331. Through the latching part 330, the latching part 330 can be first latched onto the positioning part 130 for initial positioning, and then the locking main body 310 and the positioning part 130 can be connected using a positioning pin, thereby simplifying the installation of the locking mechanism 300.

[0059] Preferably, the locking mechanism 300 further includes a gripping portion 340. The gripping portion 340 is disposed at one end of the locking body 310, facilitating the operator's grip and thus enabling the operator to install the locking mechanism 300 on the mounting base 100. In this embodiment, the gripping portion 340 may specifically be a cylindrical rod-shaped structure. In other embodiments, the gripping portion 340 may have other structures, as long as it is convenient for the operator to grip; its specific structure is not limited in this embodiment.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. 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 this utility model should be included within the protection scope of the claims of this utility model.
