Description

Technical Field

[0001] This invention relates to the field of ship structure technology, and in particular to an embedded ship structure base. Background Technology

[0002] An A-frame lifting system is a large lifting device resembling the letter "A" in shape. It is typically installed on the deck of a ship and is primarily used to safely lower or retrieve heavy, large instruments and equipment into or from the water during navigation or operation. Currently, there are two installation methods for A-frames: fixed installation and modular installation. Figure 1 As shown, the base of the A-frame is directly welded and installed onto the deck 4' of hull 1', making disassembly inconvenient; as Figure 2 As shown, the base of the A-frame can be detachably installed onto the deck 4' of the hull 1' via the common base 2'. Specifically, the A-frame and the common base 2' are connected by bolts, and the modular installation and disassembly are convenient.

[0003] While the modular installation method described above is convenient for disassembly, it also has drawbacks such as... Figure 3 As shown, a wooden floor 3' is typically laid on deck 4', with a thickness T1 of approximately 80mm. A clearance is provided at the location where the common base 2' is installed on deck 4'. Since the height T2 of the common base 2' is usually no less than 200mm, the common base 2' will protrude from the wooden floor 3'. However, after the A-frame is no longer needed and is dismantled, the protrusion of the common base 2' will affect other operations. Figure 4 As shown, to prevent the common base 2' from protruding from the wooden floor 3', the maximum height T2 of the common base can only be 80mm. Considering that the thickness T3 of the panel of the common base 2' is usually 30mm-40mm, the height T4 of the web plate is only about 40mm-50mm. According to the stress characteristics and load size, the welding requirements of the common base 2' of the A-frame usually require the web plate and the panel plate to be fully penetrated, and the web plate and the panel plate should be at least deep penetration welded. The net space of 40mm-50mm is difficult to meet the above welding requirements. The welding space is too small, and the welding quality is difficult to control. Therefore, the method of reducing the height of the common base 2' is not feasible.

[0004] Therefore, there is an urgent need to propose an embedded hull structure base to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an embedded hull structure base, which allows for the detachable installation of an A-frame via a base plate; the base plate is concealed, does not affect other operations on the hull, and has high structural stability; it also has good structural strength and is easy to manufacture.

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

[0007] An embedded hull structure base, including:

[0008] Deckboard, the deckboard is installed on the hull of the ship, the deckboard has a thickness of t1, and wooden planks can be laid on the deckboard;

[0009] A base plate, which is embedded in the deck plate, has a thickness of t3 and its upper surface does not extend beyond the wooden board. An A-frame can be detachably installed on the base plate.

[0010] A transition plate, the inner side of which is connected to the outer periphery of the base plate, and the outer side of which is connected to the deck plate, the thickness of which is t2, and t1≤t2≤t3, and the upper surface of which does not extend beyond the wooden board;

[0011] The reinforced structure is provided at the bottom of the deck plate, the bottom of the transition plate, and the bottom of the base plate to ensure watertightness inside the compartment.

[0012] As an optional technical solution for embedded hull structure base, the upper surfaces of the deck plate, the transition plate and the base plate are flush.

[0013] As an optional technical solution for embedded hull structure base, the lower surfaces of the base plate, the transition plate and the deck plate are flush.

[0014] As an optional technical solution for an embedded hull structure base, the embedded hull structure base further includes two base longitudinal girder, which are spaced apart at the bottom of the base plate along the width direction of the hull body and extend along the length direction of the hull body.

[0015] As an optional technical solution for an embedded hull structure base, the embedded hull structure base also includes two reinforcing longitudinal girder, which correspond one-to-one with the base longitudinal girder. One end of the reinforcing longitudinal girder abuts against the base longitudinal girder, and the other end extends along the length of the ship body in a direction away from the base longitudinal girder, and is connected in sequence to the bottom of the base plate, the bottom of the transition plate, and the bottom of the deck plate.

[0016] As an optional technical solution for embedded hull structure base, multiple support partitions are provided on the opposite sides of the two base longitudinal girder along the width direction of the ship body. The support partitions can abut against the bottom of the base longitudinal girder, the base plate and the transition plate. The multiple support partitions on one side of each base longitudinal girder are spaced apart along the length direction of the ship body.

[0017] As an optional technical solution for embedded hull structure base, a support elbow plate is provided between two adjacent support partitions on the same side, and the support elbow plate abuts against the outer side of the base longitudinal girder and the bottom of the base plate.

[0018] As an optional technical solution for an embedded hull structure base, the transition plate has multiple first construction holes spaced apart along its circumferential edge, and the support partition between two adjacent first construction holes has through holes.

[0019] As an optional technical solution for an embedded hull structure base, the longitudinal girder of the base is watertight. The embedded hull structure base also includes a watertight partition assembly and a watertight bottom plate. The watertight bottom plate is located at the bottom of the transition plate and is arranged opposite to the transition plate. The watertight partition assembly and the longitudinal girder of the base are connected and enclosed, and their bottoms abut against the watertight bottom plate to form a U-shaped watertight groove. The first construction hole is located between the inner and outer rings of the U-shaped watertight groove.

[0020] As an optional technical solution for an embedded hull structure base, a third construction hole is provided on the watertight base plate, and the third construction hole is located between the two longitudinal girder of the base.

[0021] The beneficial effects of this invention are:

[0022] The embedded hull structure base provided by this invention includes a deck plate, a base plate, a transition plate, and a reinforcing structure. Wooden planks can be laid on the deck plate. The base plate is embedded in the deck plate, and its upper surface does not protrude beyond the wooden planks. This embedding and installation of the base plate ensures the connection strength between the base plate and the deck plate, improving the structural stability of the base plate, while also meeting the requirement that the base plate does not protrude from the wooden planks (it is hidden within the wooden planks). An A-frame can be detachably installed on the base plate, making its disassembly and installation convenient. Furthermore, after the A-frame is removed from the base plate, since the base plate does not protrude from the wooden planks, it does not affect other operations on the hull or compromise the aesthetics.

[0023] Secondly, the inner side of the transition plate is connected to the outer periphery of the base plate, and the outer side is connected to the deck plate. The upper surface of the transition plate does not extend beyond the wooden board. The thickness of the deck plate is t1, the thickness of the transition plate is t2, and the thickness of the base plate is t3, and t1≤t2≤t3. That is to say, the transition plate is set between the deck plate and the base plate. Therefore, the transition plate plays a transition role, improves the connection strength between the base plate and the deck plate, thereby improving the stability of the base plate and reducing the manufacturing difficulty.

[0024] Furthermore, reinforcing structures are provided at the bottom of the deck plate, the bottom of the transition plate, and the bottom of the base plate to ensure the structural strength of the embedded hull structure base; the reinforcing structures ensure watertightness inside the compartment and have good drainage function.

[0042] Example 1

[0043] This embodiment provides an embedded hull structure base, which allows for the detachable installation of an A-frame via a base plate; the base plate is concealed, does not affect other operations on the hull, and exhibits high structural stability; it also boasts good structural strength and is easy to manufacture.

[0044] Specifically, such as Figure 5As shown, the embedded hull structure base includes a deck plate 1, a base plate 3, a transition plate 2, and a reinforcing structure. The deck plate 1 has a thickness of t1, and wooden planks can be laid on it. The base plate 3 is embedded in the deck plate 1, has a thickness of t3, and its upper surface does not extend beyond the wooden planks. An A-frame can be detachably installed on the base plate 3. The inner side of the transition plate 2 is connected to the outer periphery of the base plate 3, and the outer side of the transition plate 2 is connected to the deck plate 1. The thickness of the transition plate 2 is t2, and t1≤t2≤t3. The upper surface of the transition plate 2 does not extend beyond the wooden planks. Reinforcing structures are provided at the bottom of the deck plate 1, the bottom of the transition plate 2, and the bottom of the base plate 3 to ensure watertightness within the hull.

[0045] Based on the above design, the hull includes a deck plate 1 on which wooden planks can be laid; a base plate 3 is embedded in the deck plate 1, and the upper surface of the base plate 3 does not protrude beyond the wooden planks. The embedding and installation of the base plate 3 ensures the connection strength between the base plate 3 and the deck plate 1, improves the structural stability of the base plate 3, and also meets the requirement that the base plate 3 does not protrude from the wooden planks (it is hidden within the wooden planks). An A-frame can be detachably installed on the base plate 3, making the disassembly and installation of the A-frame convenient; and after the A-frame is removed from the base plate 3, since the base plate 3 does not protrude from the wooden planks, it does not affect other operations on the hull, nor does it affect the aesthetics.

[0046] Secondly, the inner side of the transition plate 2 is connected to the outer periphery of the base plate 3, and the outer side of the transition plate 2 is connected to the deck plate 1. The upper surface of the transition plate 2 does not extend beyond the wooden board. The thickness of the deck plate 1 is t1, the thickness of the transition plate 2 is t2, and the thickness of the base plate 3 is t3, and t1≤t2≤t3. That is to say, the transition plate 2 is set between the deck plate 1 and the base plate 3. Therefore, the transition plate 2 plays a transition role, improves the connection strength between the base plate 3 and the deck plate 1, thereby improving the stability of the base plate 3 and reducing the manufacturing difficulty.

[0047] Furthermore, the bottom of the deck plate 1, the bottom of the transition plate 2, and the bottom of the base plate 3 are reinforced to ensure the structural strength of the embedded hull structure base; the reinforced structure ensures watertightness inside the compartment and has good drainage function.

[0048] It should be noted that the thickness of the deck plate 1 is usually relatively thin; the thickness t3 of the base plate 3 ranges from 30mm to 50mm; and the thickness t2 of the transition plate 2 should be determined based on strength calculations.

[0049] Optionally, the ship body also includes a bottom plate, a hull side, and a stern plate 14, etc. The bottom plate is arranged opposite to the deck plate 1, and the hull side and stern plate 14 surround the outer perimeter of the bottom plate and the deck plate 1. The bottom of the deck plate 1 is provided with multiple parallel deck ribs 9, which are spaced apart along the width direction of the ship body and extend along the length direction of the ship body.

[0050] Of course, in this embodiment, the two sets of deck longitudinals 9 are respectively arranged on both sides of the transition plate 2 along the width direction of the ship body.

[0051] Optionally, the base plate 3 is provided with a plurality of bolt holes 4, which are spaced apart along the circumferential edge of the base plate 3, and the A-frame is installed on the base plate 3 by bolts.

[0052] like Figure 6 , Figure 7 and Figure 8 As shown, the lower surfaces of the base plate 3, transition plate 2, and deck plate 1 are flush, and the deck plate 1, transition plate 2, and base plate 3 form a stepped structure with high structural strength; and avoid the base plate 3 from excessively occupying the space of the ship body at the bottom of the deck plate 1.

[0053] At this time, the upper surfaces of the base plate 3 and the transition plate 2 both extend beyond the upper surface of the deck plate 1, that is, the top protrudes from the deck plate 1. However, the top of the base plate 3 and the transition plate 2 does not extend beyond the wooden board. After the A-frame is disassembled, a depression will be formed at the base plate 3 and the transition plate 2. For safety reasons, a safety cover plate can be installed at the depression so that the safety cover plate is flush with the upper surface of the wooden board.

[0054] Safety covers can be laid wire mesh or other coverings to prevent people from falling.

[0055] Optionally, the embedded hull structure base also includes two base longitudinal girder 5, which are spaced apart at the bottom of the base plate 3 along the width direction of the hull and extend along the length direction of the hull, increasing the structural strength of the bottom of the base plate 3. Compared with the traditional common base, the base plate 3 in this structure is similar to the panel of the common base, and the base longitudinal girder 5 is similar to the web of the common base.

[0056] Furthermore, the embedded hull structure base also includes two reinforcing longitudinal girder 8, which correspond one-to-one with the base longitudinal girder 5. One end of the reinforcing longitudinal girder 8 abuts against the base longitudinal girder 5, and the other end extends along the length of the ship body in a direction away from the base longitudinal girder 5, and is connected in sequence to the bottom of the base plate 3, the bottom of the transition plate 2 and the bottom of the deck plate 1, thereby strengthening the bottom structural strength of the base plate 3, the transition plate 2 and the deck plate 1.

[0057] The above design increases the strength of the base plate 3 along the length of the ship body (hereinafter referred to as longitudinal). In order to further improve the structural strength of the base plate 3, it is also necessary to increase it along the width of the ship body (hereinafter referred to as transverse). Therefore, along the width of the ship body, multiple support partitions 6 are provided on the opposite sides of the two base longitudinal girder 5. The support partitions 6 can abut against the bottom of the base longitudinal girder 5, the base plate 3 and the bottom of the transition plate 2. Multiple support partitions 6 on one side of each base longitudinal girder 5 are spaced apart along the length of the ship body, which can increase the side wall strength of the base longitudinal girder and also increase the transverse strength of the bottom of the base plate 3.

[0058] Furthermore, a support elbow plate 7 is provided between two adjacent support partitions 6 on the same side. The support elbow plate 7 abuts against the outer side of the base longitudinal girder 5 and the bottom of the base plate 3, further increasing the side wall strength of the base longitudinal girder 5 and the transverse strength of the bottom of the base plate 3.

[0059] For ease of construction, the transition plate 2 is provided with multiple first construction holes 10 at intervals along its circumferential edge; the support partition 6 located between two adjacent first construction holes 10 is provided with through holes, so that construction personnel can pass through the through holes to carry out construction on various parts.

[0060] Typically, the first construction hole 10 is an oval hole of not less than 200mm × 300mm.

[0061] Furthermore, since the openings on the transition plate 2 compromise the watertightness of the hull, to ensure the watertightness of the hull, firstly, the base longitudinal girder 5 must be watertight. The embedded hull structure base also needs to include a watertight bulkhead assembly and a watertight bottom plate 18. The watertight bottom plate 18 is located at the bottom of the transition plate 2 and is positioned opposite to the transition plate 2. The watertight bulkhead assembly and the base longitudinal girder 5 are connected and enclosed, with their bottoms abutting against the watertight bottom plate 18, forming a U-shaped watertight groove. The first construction hole 10 is located between the inner and outer rings of the U-shaped watertight groove. When rainwater enters the U-shaped watertight groove through the first construction hole 10, the accumulated water can be diverted to the stern (i.e., the stern) of the hull through the drainage holes provided on the support bulkhead 6, and finally discharged through the second construction hole on the stern sealing plate 14 of the hull. Alternatively, a drainage pipe can be installed on the bottom plate to divert the water to the outside of the hull.

[0062] In this embodiment, the watertight partition assembly includes a watertight longitudinal partition 11 and a watertight transverse partition 12. The watertight longitudinal partition 11 is located on the two longitudinal sides of the outer ring of the U-shaped watertight groove; the watertight transverse partition 12 is located on the two transverse sides of the inner ring and the two transverse sides of the outer ring of the U-shaped watertight groove.

[0063] Furthermore, such as Figure 9 and Figure 10As shown, a third construction hole 17 is provided on the watertight base plate 18. The third construction hole 17 is located between the two base longitudinal girders 5, which facilitates the construction of the base longitudinal girders 5.

[0064] Furthermore, the watertight base plate 18 is fully welded to the base longitudinal girder 5, the watertight longitudinal diaphragm 11, and the watertight transverse diaphragm 12 to ensure watertight performance, and the third construction hole 17 should be large enough within the inner circle of the U-shaped watertight trench to provide sufficient construction space for the base longitudinal girder 5.

[0065] In this embodiment, when the height of the base longitudinal girder 5 and the height of other parts of the ship body (such as the deck beam 13 web) are appropriate, the watertight bottom plate 18 can be welded to the panels of the deck beam 13 and the reinforcing longitudinal girder 8, resulting in better strength. The watertight bottom plate 18 can also be installed at an angle to facilitate drainage, but sufficient construction space should be ensured.

[0066] Optionally, the tail seal plate 14 is provided with a thickened plate 15. The thickness of the plate is determined according to strength calculations. The thickened plate 15 should generally cover the base longitudinal girder 5, the watertight longitudinal partition plate 11, and the watertight bottom plate 18. A vertical truss 16 is provided at the tail seal plate 14, aligned with the lower part of the base longitudinal girder 5, to support the base longitudinal girder 5. The watertight longitudinal partition plate 11 is connected to the vertical truss 16 on the tail seal plate 14.

[0067] The aforementioned base plate 3, transition plate 2, base longitudinal girder 5, support partition 6, support elbow plate 7, watertight partition group and watertight bottom plate 18 together form the base reinforcement structure on one side of the A-frame, and the base reinforcement structure on the other side of the A-frame is symmetrically arranged to form a complete A-frame base reinforcement structure group.

[0068] Example 2

[0069] This embodiment provides an embedded hull structure base, which differs from the embedded hull structure base in Embodiment 1 in that:

[0070] The upper surfaces of deck plate 1, transition plate 2 and base plate 3 are flush, meaning that the lower surfaces of transition plate 2 and base plate 3 protrude from the lower surface of deck plate 1. This ensures that base plate 3 does not protrude from the wooden planks, and allows the original wooden planks to be laid on transition plate 2 and base plate 3 after the A-frame is removed to serve as safety covers, while also restoring the original aesthetics.

[0071] The embedded hull structure base provided in this embodiment differs from the embedded hull structure base provided in Embodiment 1 only in the one mentioned above; all other aspects are the same and will not be described again here.

[0072] 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.
