Description

Technical Field

[0001] The present invention relates to a limiting device for an independent cabin of a ship, and particularly to a combined vertical limiting device for an independent cabin of a ship, belonging to the technical field of independent cabins of ships. Background Art

[0002] An independent cabin of a ship is a cargo hold of a ship specifically used for transporting liquid cargo. This cargo hold is separated from the main structure of the ship, so that the cargo can be stored, transported, and unloaded in an independent cabin.

[0003] Generally, an independent cabin is provided with a set of complex support systems. During operation, various loads such as the weight of the liquid cargo hold and the cargo, the additional load of movement, and the load of the temperature during loading and unloading are transmitted to the main hull structure through the liquid cargo hold support system. According to different functions, the liquid cargo hold support system is provided with 4 types of supports: vertical supports provide vertical support for the liquid cargo hold, anti-roll supports and longitudinal limiting supports are used to limit the relative displacement between the liquid cargo hold and the hull, and anti-floating supports prevent the independent cabin from floating up and colliding with the main hull when the hull is damaged and flooded, causing damage.

[0004] A variety of supports should be reasonably arranged and sufficient in number, and meet the requirements of support and limiting functions. Currently, the supports are usually composed of a support structure, laminated wood, epoxy resin, and stainless steel sheets, with complex structures and construction processes.

[0005] The anti-floating support is to prevent the liquid cargo hold from floating up and colliding with the main hull when the hull is damaged and flooded, and only functions under specific accident conditions. During the life cycle of the vast majority of ships, the anti-floating support will not play a role, but the anti-floating support, laminated wood, and strengthening of the structure are all necessary.

[0006] The prior art generally sets an anti-floating support at the upper part of the independent liquid cargo hold. When the hull is damaged and flooded, the buoyancy received by the independent cabin is greater than its own gravity, and the liquid cargo hold floats up until the anti-floating support contacts the hull structure, thereby limiting the displacement of the independent cabin. As Figure 1 and Figure 3 shown. Summary of the Invention

[0007] Based on this, the purpose of the present invention is to provide a simpler and more economical anti-floating support (combined vertical limiting device for an independent cabin of a ship), which can effectively prevent the liquid cargo hold from floating up when the hull is damaged and flooded, and ensure the safety of the independent liquid cargo hold and the hull structure.

[0008] The present invention adopts the following technical solutions:

[0009] A combined vertical limit device for an independent cabin of a ship, comprising a combined vertical support 7, the combined vertical support 7 including a structure 701 above the support, a structure 702 below the support, laminated wood 704, and an anti-floating limit structure; the structure 702 below the support is in abutment with the structure 701 above the support through the laminated wood 704 and is connected by the anti-floating limit structure in a tie connection; the combined vertical support 7 is arranged in the gap between the bottom of the independent cabin and the hull structure 6; the upper end of the structure 701 above the support is fixedly connected to the independent cabin structure 5, and the structure 702 below the support is fixedly connected to the hull structure 6.

[0010] The present invention cancels the anti-floating loading at the top of the independent cabin, integrates the anti-floating device at the bottom of the independent cabin, simplifies the design of the independent cabin support, and makes the design and construction simpler, more economical and efficient.

[0011] Preferably, the anti-floating limit structure is a tie-type limit bolt 703.

[0012] Preferably, there are a plurality of the limit bolts 703, which are arranged around the laminated wood 704.

[0013] Preferably, the anti-floating limit structure is a clamping plate 705.

[0014] Furthermore, the upper and lower structures 701 and the lower limit structure 702 each have a flat plate, the clamping plate 705 is U-shaped, and its two inner sides are respectively clamped to one of the flat plates to form a state that can be clamped.

[0015] Preferably, no anti-floating support is provided in the gap between the top of the independent cabin and the hull structure.

[0016] Furthermore, an anti-rolling upper support 1 is provided in the gap between the top of the independent cabin and the hull structure, and an anti-rolling lower support 3 is provided in the gap between the bottom of the independent cabin and the hull structure.

[0017] Preferably, the anti-floating limit structure is not stressed under normal conditions, and only plays a vertical anti-floating limit function when the ship is in a broken-cabin still water state and the independent cabin floats up.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1) In the prior art, the anti-floating device is arranged at the top of the liquid cargo cabin, and a large number of strengthening structures are required both inside the independent cabin and the hull structure to meet the strength requirements of the anti-floating device. In the present invention, a tie-type upper and lower connecting bolt or a clamping plate is added to the vertical support at the bottom of the independent cabin to realize the function of restricting the floating up of the independent cabin. The structural strength of the original vertical support is utilized without additional structural strengthening, and a large amount of steel cost is saved.

[0020] 2) The pull - type bolts or clamping plates are added to replace the top anti - floating supports, which greatly reduces the costs of the support steel, laminated wood, and epoxy resin.

[0021] 3) Only bolts need to be installed at the bottom of the independent tank, and there is no need to install laminated wood at high altitudes, in inclined and narrow spaces, which greatly reduces the construction difficulty and cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0028] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0029] Embodiment 1 (comparative embodiment of the prior art):

[0030] Figure 1 is a cross - sectional view (elevation) showing a ship, in which there are certain gaps between the independent liquid cargo tank and the hull structure, and anti - rolling upper supports 1, anti - floating supports 2, anti - rolling lower supports 3, vertical supports 4, etc. are arranged in these gaps.

[0031] Among them, the structure of the vertical support 4 is as Figure 2 shown, Figure 2 the small figure on the left is Figure 1 the partial enlarged view in Figure 2 and the small figure on the right is the cross - sectional view of the small figure on the left. This vertical support 4 plays a role in vertical support.

[0032] Combined withFigure 1 and Figure 3 , a buoyancy restraint support 2 is provided at the upper part of the independent liquid cargo tank. When the hull is damaged and flooded, the buoyancy force received by the independent tank is greater than its own gravity, and the liquid cargo tank floats up until the buoyancy restraint support contacts the hull structure, thereby restricting the displacement of the independent tank. As shown in Figure 3 .

[0033] It can be seen from this that the buoyancy restraint support 2 has a complex composition and needs to be composed of a support structure, laminated wood, epoxy resin, etc.; both the independent tank and the hull structure near the buoyancy restraint support 2 need to be strengthened; the installation process of the buoyancy restraint support 2 is complex and the installation accuracy requirements are relatively high; at a very low probability of use (the probability that the buoyancy restraint support needs to bear force is extremely low), the cost of the additionally provided buoyancy restraint support at the top is too high.

[0034] Embodiment 2:

[0035] Based on the above contradictions, this embodiment provides a more economical buoyancy restraint device for the independent tank. The main design scheme of the method of the present invention is: integrating the buoyancy restraint support with the bottom vertical support, so that the vertical support can not only play a vertical support role, but also play a buoyancy restraint and limit role.

[0036] Specifically, referring to Figure 4-5 , a combined vertical limiting device for a ship's independent tank, comprising a combined vertical support 7, and the combined vertical support 7 includes a structure 701 above the support, a structure 702 below the support, laminated wood 704, and a buoyancy restraint and limit structure; the structure 702 below the support is in abutment with the structure 701 above the support through the laminated wood 704 and is connected by the buoyancy restraint and limit structure in a tension connection; the combined vertical support 7 is arranged in the gap between the bottom of the independent tank and the hull structure 6; the upper end of the structure 701 above the support is fixedly connected to the independent tank structure 5, and the structure 702 below the support is fixedly connected to the hull structure 6. No buoyancy restraint support is provided in the gap between the top of the independent tank and the hull structure.

[0037] This solution cancels the buoyancy restraint at the top of the independent tank and integrates the buoyancy restraint device at the bottom of the independent tank, simplifying the design of the independent tank support, and making the design and construction simpler, more economical and efficient.

[0038] As an alternative embodiment, as shown in Figure 4 , the buoyancy restraint and limit structure is a tension-type limit bolt 703.

[0039] In this embodiment, a plurality of the limit bolts 703 are provided and arranged around the laminated wood 704.

[0040] As another alternative embodiment, as shown in Figure 5 , the buoyancy restraint and limit structure is a clamping plate 705.

[0041] In this embodiment, continue to refer to Figure 5, the upper and lower structure 701 and the lower limiting structure 702 each have a flat plate. The clamping plate 705 is U-shaped, and its two inner sides are respectively clamped with one of the flat plates to form a state that can be clamped.

[0042] In this embodiment, an anti-rolling upper support 1 is arranged in the gap between the top of the independent cabin and the hull structure, and an anti-rolling lower support 3 is arranged in the gap between the bottom of the independent cabin and the hull structure.

[0043] The anti-floating limiting structure is not stressed under normal conditions, and only plays a vertical anti-floating limiting function when the ship is damaged and the independent cabin floats up.

[0044] In the prior art, the anti-floating device is arranged on the top of the liquid cargo tank. A large number of strengthening structures are required inside the independent cabin and the hull structure to meet the strength requirements of the anti-floating device. In the present invention, a pull-type upper and lower connecting bolt or a clamping plate is added to the vertical support at the bottom of the independent cabin to realize the function of restricting the floating of the independent cabin. The structural strength of the original vertical support is utilized without additional structural strengthening, thus saving a large amount of steel cost. The addition of the pull-type bolt or clamping plate replaces the top anti-floating support, greatly reducing the cost of the support steel, laminated wood and epoxy. Only bolts need to be installed at the bottom of the independent cabin, and there is no need to install laminated wood at high altitude, on slopes and in narrow spaces, greatly reducing the construction difficulty and cost.

[0045] The above are the preferred embodiments of the present invention. Those of ordinary skill in the art can also make various transformations or improvements on this basis. Without departing from the general concept of the present invention, these transformations or improvements should fall within the scope of protection required by the present invention.
