A support reinforcement device for independent cargo compartments

Abstract

This invention discloses a support and reinforcement device for independent cargo holds, relating to the field of ship cargo hold technology. It includes a mounting base plate fixedly connected to the ship, two sliding brackets each with a cargo cover plate fixed to them, and a downward braking assembly for vertically locking a vertical sleeve fixed to a support column. A reinforcing arc plate is slidably mounted on the side of each cargo cover plate facing the mounting base plate. This invention uses two cargo cover plates and a support sleeve to form a cargo storage space. In extreme situations such as deck collapse, the protective top frame, supported by the support column and vertical sleeve, effectively protects the cargo cover plates. The drive slider in the retraction transmission assembly pushes against the tilting frame, causing the two tilting frames to slide towards each other and pull the two cargo cover plates together. This space contraction reduces the internal volume, significantly improving the pressure resistance of the cargo cover plates and ensuring effective protection of the cargo.

Description

Technical Field

[0001] This invention relates to the field of ship cargo hold technology, specifically a support and reinforcement device for independent cargo hold compartments. Background Technology

[0002] Cargo holds are the internal spaces below deck, primarily used for storing and transporting goods. Their loading capacity is limited by weight, volume, door size, and floor load-bearing capacity. Cargo holds are classified into types such as container holds, refrigerated cargo holds, liquid cargo holds, and dry cargo holds. Among these, dry cargo holds are the most common cargo storage areas, typically located below the main deck, and are used to load various dry goods, such as grains, textiles, and machinery. Depending on the ship type, they can be divided into multiple independent compartments.

[0003] Existing independent cargo holds on ships have relatively fixed structures. In extreme situations, such as significant deformation or collapse of the ship's deck above the independent cargo hold, the volume of the independent cargo hold cannot be forced to contract under external pressure. This results in low overall compressive strength and difficulty in ensuring stability, ultimately leading to severe damage to the cargo inside. To address these technical shortcomings, a support and reinforcement device for independent cargo holds is provided to solve these problems. Summary of the Invention

A vertical frame is fixed to the side wall of each hatch cover. An inclined frame is fixed on the vertical frame. A retraction transmission assembly for driving the inclined frame to slide horizontally is installed on the mounting base plate. A reinforcing arc plate is slidably installed on the side of each hatch cover facing the mounting base plate. A docking transmission assembly for driving the two reinforcing arc plates to slide relative to the hatch cover and dock is installed on the hatch cover plate.

[0009] As an improvement of the present invention: the docking transmission assembly further includes a fixing frame fixed to the cover plate, a rack that meshes with the transmission gear is vertically slidably mounted on the fixing frame, an extension rod extending vertically downward is fixed to the bottom of the fixing frame, a sliding sleeve fixed to the rack is slidably sleeved on the extension rod, and a vertical spring is fixedly connected between the sliding sleeve and the fixing frame.

[0010] As an improvement of the present invention: a horizontally extending transmission push plate is fixed to the side wall of the extension plate, and a guide wheel corresponding vertically to the transmission push plate is rotatably mounted on the top of the straight rack.

[0011] As an improvement of the present invention: the locking assembly includes a receiving sleeve plate fixed to the side wall of the cabin cover plate, a check wedge plate is slidably installed on the receiving sleeve plate, a push spring is fixed between the check wedge plate and the receiving sleeve plate, and a plurality of wedge-shaped slots are opened on the side of the reinforcing arc plate away from the arc-shaped rack, and the check wedge plate is engaged and adapted with the wedge-shaped slots.

[0012] As an improvement of the present invention: a centrally located I-shaped docking block is fixed at the bottom of the support sleeve, and two right-angle grooves are provided on the I-shaped docking block for the two reinforcing arc plates to engage respectively.

[0013] As an improvement of the present invention: the downward braking assembly includes two receiving grooves formed in the support column, a rotating plate is rotatably installed in the receiving groove, the rotating plate abuts against the inner wall of the vertical sleeve, and a lateral slot is formed on the side wall of the vertical sleeve for the rotating plate to extend, the lateral slot being located above the rotating plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention constructs a cargo storage space using two hatch covers and a support sleeve. In extreme situations such as a ship's deck collapse, the protective top frame can effectively protect the hatch covers under the support of the support columns and vertical sleeves. When the protective top frame is compressed and moves vertically downward, the drive slider in the retraction transmission assembly can push the tilting frame, causing the two tilting frames to slide towards each other and pull the two hatch covers together in the middle. By shrinking the space, the internal volume is reduced, significantly improving the compressive strength of the hatch covers and ensuring effective protection of the cargo.

[0018] 2. In this invention, when the protective top frame moves vertically downward, the straight rack in the docking transmission assembly moves downward and drives the transmission gear to rotate. This causes the transmission gear to drive the arc rack to slide the reinforcing arc plate relative to the cabin cover plate. At this time, during the sliding process of the two cabin cover plates towards each other, the two reinforcing arc plates approach each other and are engaged with the I-shaped docking block. This achieves effective internal reinforcement support after the space formed by the two cabin cover plates and the support sleeve plate shrinks, realizing automatic reinforcement during the pressure process of the cabin cover plate, and greatly improving the support strength of the ship's independent cabin.

Detailed Implementation

[0030] The technical solution of the present invention will be further described in detail below with reference to specific embodiments:

[0031] First Embodiment

[0032] Please see the appendix Figure 1 -Appendix Figure 10A support reinforcement device for an independent cargo hold includes a mounting base 1 fixedly connected to a ship. A pair of sliding brackets 26 are slidably mounted on the mounting base 1, and a cargo hold cover 5 is fixed to each of the two sliding brackets 26. The two cargo hold covers 5 are arranged opposite each other. Four vertically extending rectangular support columns 4 are fixedly mounted on the mounting base 1. A vertical sleeve 3 is slidably fitted onto each support column 4. A support spring 30 is fixed between the vertical sleeve 3 and the support column 4. A downward braking assembly for vertically locking the vertical sleeve 3 is fixed to the support column 4. A protective top frame 2, fixedly connected to the vertical sleeve 3, is installed above the cargo hold cover 5 to prevent... Below the top cover 2, a support sleeve 37 fixed to the ship is installed. The ends of the two hatch covers 5 away from the translation bracket 26 are slidably extended into the support sleeve 37. A vertical frame 12 is fixed to the side wall of each hatch cover 5. An inclined frame 11 is fixed on the vertical frame 12. A retraction transmission assembly for driving the inclined frame 11 to slide horizontally is installed on the mounting base plate 1. A reinforcing arc plate 6 is slidably installed on the side of each hatch cover 5 facing the mounting base plate 1. A docking transmission assembly for driving the two reinforcing arc plates 6 to slide relative to the hatch cover 5 and dock is installed on the hatch cover 5. A reinforcing rib plate 8 is fixed on the side of the hatch cover 5 facing the mounting base plate 1.

[0033] The two hatch covers 5, support sleeves 37, and mounting base 1 constitute the internal storage space of the ship's independent cargo hold compartment. The protective top frame 2 provides protection for the top of the hatch covers 5. When the ship's deck deforms or even collapses, the protective top frame 2 can withstand external vertical pressure to strengthen the support. The vertical sleeves 3, support columns 4, and the support springs 30 between them provide excellent elastic support and significantly buffer external pressure. When the protective top frame 2 moves vertically downward, the two tilting frames 11 can be driven to slide horizontally towards each other through the set retraction transmission assembly, so that the two hatch covers 5 move closer to each other and compress the storage space to obtain more stable pressure resistance.

[0034] In addition, the retraction transmission assembly includes an extension plate 13 fixed to the bottom of the protective top frame 2, an inclined rod 38 fixed on the inclined frame 11, a drive slider 29 slidably sleeved on the inclined rod 38 fixed to the bottom of the extension plate 13, and a connecting spring 39 fixed between the drive slider 29 and the inclined frame 11. With the above arrangement, when the protective top frame 2 is subjected to greater pressure, the protective top frame 2 drives the extension plate 13 fixed on it to move vertically downward. At this time, the extension plate 13 drives the drive slider 29 to slide along the inclined frame 11. The inclined frame 11 slides under the pushing action of the drive slider 29, and the two inclined frames 11 move closer to each other. This achieves the effect of the two cabin cover plates 5 moving closer to each other under the action of the translation bracket 26 and realizing the space retraction effect, which effectively strengthens the strength and greatly improves the pressure resistance of the cabin cover plate 5 and the support sleeve plate 37.

[0035] The docking transmission assembly includes a transmission gear 17 rotatably mounted on the hatch cover plate 5. Several guide frames 9 are fixed on the hatch cover plate 5. A reinforcing arc plate 6 is slidably mounted between the guide frames 9 and the hatch cover plate 5. An arc-shaped rack 20, meshing with the transmission gear 17, is embedded and fixed on the reinforcing arc plate 6. A locking assembly for locking the reinforcing arc plate 6 is installed on the hatch cover plate 5. A horizontally extending transmission push plate 16 is fixed to the side wall of the extension plate 13. A guide wheel 21, vertically corresponding to the transmission push plate 16, is rotatably mounted on the top of the rack 14. A centrally located I-shaped docking block 10 is fixed to the bottom of the support sleeve plate 37. The I-shaped docking block 10 has two right-angle slots 7 for engaging two reinforcing arc plates 6 respectively.

[0036] In addition, the docking transmission assembly also includes a fixing frame 22 fixed on the cover plate 5. A rack 14 that meshes with the transmission gear 17 is vertically slidably mounted on the fixing frame 22. An extension rod 25 extending vertically downward is fixed to the bottom of the fixing frame 22. A sliding sleeve 23 fixed on the rack 14 is slidably sleeved on the extension rod 25. A vertical spring 24 is fixedly connected between the sliding sleeve 23 and the fixing frame 22.

[0037] Based on the above structural configuration, when the extension plate 13 moves vertically downward, the extension plate 13 drives the transmission push plate 16 to move vertically downward and pushes against the guide wheel 21. At this time, the guide wheel 21 drives the rack 14 to move vertically downward. The sliding sleeve 23 fixed on the rack 14 moves vertically downward relative to the extension rod 25, which plays a stabilizing guiding role. The rack 14 drives the transmission gear 17 to rotate. The transmission gear 17 meshes with the arc rack 20 and drives the reinforcing arc plate 6 to slide relative to the cabin cover plate 5. At this time, the reinforcing arc plate 6 slides linearly with the cabin cover plate 5. The ends of the two reinforcing arc plates 6 away from the translation bracket 26 move closer and are finally locked in the right angle groove 7 of the I-shaped docking block 10. The I-shaped docking block 10 realizes the stable docking of the two reinforcing arc plates 6. After the storage space formed by the cabin cover plate 5 shrinks, the two reinforcing arc plates 6 provide internal reinforcement support, which greatly improves the compressive strength of the storage space.

[0038] In addition, the locking assembly includes a receiving sleeve 18 fixed to the side wall of the cabin cover 5, a check wedge 19 slidably installed on the receiving sleeve 18, a push spring 27 fixed between the check wedge 19 and the receiving sleeve 18, and a plurality of wedge-shaped slots 28 are provided on the side of the reinforcing arc plate 6 away from the arc-shaped rack 20, and the check wedge 19 is engaged with the wedge-shaped slots 28.

[0039] During the sliding process of the reinforcing arc plate 6 relative to the cabin cover plate 5, the anti-return wedge plate 19 slides relative to the cabin cover plate 5. When the two reinforcing arc plates 6 are connected, under the elastic pushing action of the push spring 27, the anti-return wedge plate 19 is inserted into the corresponding wedge-shaped slot 28, which plays a locking role in the position of the reinforcing arc plate 6, ensuring that the two reinforcing arc plates 6 and the I-shaped connecting block 10 are firmly connected and locked, further improving the structural stability and support strength.

[0040] Second Embodiment

[0041] Please see the appendix Figure 1 -Appendix Figure 10 Based on the first embodiment, the downward braking assembly of this device includes two receiving grooves 40 formed within the support column 4. A rotating plate 31 is rotatably mounted within each receiving groove 40, and the rotating plate 31 abuts against the inner wall of the vertical sleeve 3. A lateral slot 15 for the rotating plate 31 to extend is formed on the side wall of the vertical sleeve 3, and the lateral slot 15 is located above the rotating plate 31. When the protective top frame 2 is subjected to vertical downward pressure, the protective top frame 2 drives the vertical sleeve 3 to move vertically downward relative to the support column 4. The support spring 30 provides excellent elastic support and buffering shock absorption, reducing the impact and effectively improving the protection effect on the cabin cover 5.

[0042] The downward braking assembly also includes a locking part 32 fixed to the upper end of the rotating plate 31. A pushing part 35 is fixed to the end of the rotating plate 31 away from the locking part 32. A stop block 36 corresponding to the rotation of the pushing part 35 is fixed on the support column 4. A rotating shaft 33 located in the receiving groove 40 is rotatably mounted on the support column 4. The rotating plate 31 is fixed on the rotating shaft 33. A torsion spring 34 is fixed between the rotating plate 31 and the support column 4.

[0043] When the vertical sleeve 3 moves down to the lateral slot 15 on it and aligns with the snap-fit ​​part 32 on the rotating plate 31, under the torsional force of the torsion spring 34, the rotating plate 31 drives the snap-fit ​​part 32 to rotate toward the lateral slot 15. Finally, the snap-fit ​​part 32 snaps into the lateral slot 15, effectively braking the vertical sleeve 3 during its downward movement. This prevents the vertical sleeve 3 from being pushed upward after the support spring 30 is compressed and rebounds. At this time, the positions of the extension plate 13 and the drive slider 29 are stable, meaning that the positions of the two cover plates 5 after they come together are effectively locked, greatly improving the robustness of the support structure.

[0044] In summary, the present invention constructs a cargo storage space using two hatch covers 5 and a support sleeve 37. In extreme cases such as a ship deck collapse, the protective top frame 2 can effectively protect the hatch covers 5 under the support of the support column 4 and the vertical sleeve 3. When the protective top frame 2 is pressed and moves vertically downward, the drive slider 29 in the shrinkage transmission assembly can push against the tilting frame 11, causing the two tilting frames 11 to slide towards each other and drive the two hatch covers 5 to converge towards the middle. By shrinking the space, the internal volume is reduced, significantly improving the pressure resistance of the hatch covers 5 and ensuring effective protection of the cargo. This invention utilizes the protective top frame 2, which, when moving vertically downwards, drives the transmission gear 17 to rotate via the downward movement of the straight rack 14 in the docking transmission assembly. This causes the transmission gear 17 to drive the arc rack 20, which in turn drives the reinforcing arc plate 6 to slide relative to the cabin cover plate 5. During this sliding process of the two cabin cover plates 5 towards each other, the two reinforcing arc plates 6 move closer together and engage with the I-shaped docking block 10. This achieves effective internal reinforcement support after the space formed by the two cabin cover plates 5 and the support sleeve plate 37 contracts, and realizes automatic reinforcement during the pressure process of the cabin cover plate 5, greatly improving the support strength of the ship's independent cabin.
