Description

Technical Field

[0001] The utility model belongs to the technical field of ship facilities, and in particular relates to a detachable ship deckhouse base. Background Art

[0002] The deckhouse is an infrastructure equipped on all kinds of ships. It is a relatively closed space set on the deck of the ship for crew activities indoors, including the wheelhouse, crew activity room, etc. Existing deckhouses are usually fixed structures, that is, they are directly installed and fixed on the deck of the ship and cannot be disassembled, moved or shifted at will. However, for ships used for construction in specific scenarios, the deckhouse of the ship has the requirements of displacement and temporary disassembly and reinstallation. For example, in the construction process of some silting ships and dredging ships (including but not limited to cutter suction dredgers, trailing suction dredgers and auxiliary anchor boats, etc.), due to the height limit requirements for crossing the bridge, the height of the ship needs to be lowered as a whole in order to successfully cross the bridge and reach the project site. If the bridge cannot be crossed smoothly, normal construction cannot be carried out.

[0003] For the aforementioned construction vessels, lowering the overall height of the ship by disassembling and temporarily transferring the deckhouse is an effective technical means to solve the bridge height limit and pass through the bridge smoothly. However, the existing fixed ship deckhouse structure does not support the aforementioned rapid disassembly and temporary transfer operations, which brings troubles to crossing the bridge in height-restricted scenarios. The existing operation method is usually to cut the deckhouse to meet the height limit requirements, and then weld it back after the ship completes the bridge crossing. This method has the following defects: First, the operation is cumbersome and time-consuming, which affects the construction period of the ship; second, the cutting and welding restoration method makes it difficult to restore the deckhouse to its original state, and in extreme cases even affects the overall structural strength of the ship; third, the cutting and welding restoration method has operational safety issues and is prone to fires caused by cutting and welding sparks. In summary, it is necessary to develop and design a technical means that can meet the needs of flexible disassembly and assembly of ship deckhouses to solve the aforementioned technical problems when ships face height-restricted bridge crossing scenarios. Utility Model Content

[0004] The purpose of the utility model is to provide a detachable ship deckhouse base, which is flexible and easy to operate, reduces the impact on the ship construction period, and can still restore the deckhouse to its original state after multiple temporary disassembly and transfer operations, thereby ensuring the safety of the ship's height-restricted bridge crossing.

[0005] The technical solution adopted by the utility model is: a detachable ship deckhouse base, comprising a deckhouse base installed and fixed at the bottom of the deckhouse and a deck base arranged on the ship deck, the deckhouse base, the deck base and the ship deck being detachably connected; the deckhouse base comprises a bottom upper base fixedly connected to the bottom of the deckhouse at the top and a bottom lower base installed and fixed below the bottom upper base, a positioning socket that does not penetrate upward is provided at the center position of the bottom lower base; the deck base comprises a plate base and a positioning connecting column installed and fixed at the middle position of the plate base, the deckhouse base is superimposed on the deck base and the positioning connecting column is inserted into the positioning socket; a plurality of threaded holes are provided at the bottom of the bottom lower base, a plurality of connecting holes are provided at corresponding positions of the plate base and the ship deck, and the bottom lower base, the plate base and the ship deck are fixedly connected by a plurality of assembly screws.

[0006] Preferably, the bottom upper base includes a vertical middle support plate and side reinforcement plates welded and installed on both sides of the middle part of the middle support plate, the length dimension of the top edge of the middle support plate is significantly larger than the length dimension of the bottom edge, the top edges of the middle support plate and the side reinforcement plates are welded and fixed to the bottom of the deckhouse, and the bottom edges of the middle support plate and the side reinforcement plates are welded and fixed to the top of the bottom lower base.

[0007] Preferably, a vertically penetrating center hole is provided in the middle of the base on the plate, and the lower portion of the positioning connecting column is inserted into the upper portion of the center hole and fixed by welding.

[0008] Preferably, the bottom of the positioning socket is open, the top of the positioning connection column is conical, and the inner diameter of the positioning socket is equal to the outer diameter of the positioning connection column.

[0009] Preferably, a rubber sealing gasket is provided between the bottom lower base and the plate upper base.

[0010] The advantages and positive effects of the utility model are:

[0011] The present invention provides a detachable ship deckhouse base with a rational structural design, which is applied to the fixed connection between the ship deck and the deckhouse. It transforms the existing fixed connection between the ship deck and the deckhouse into a structure that uses a detachable base for transfer connection. Therefore, the ship deckhouse can be disconnected from the ship deck when necessary, allowing the ship body and the deckhouse to be moved separately. This effectively solves the problem of height restrictions when crossing bridges in existing ship construction projects. By temporarily removing the deckhouse from the ship body, the overall height of the ship is lowered to smoothly cross the bridge (the deckhouse is hoisted and transferred to pass over the bridge or transferred to an auxiliary ship to pass under the bridge), the feasibility and convenience of existing construction ships crossing bridges are improved.

[0012] The detachable base of this utility model consists of a deckhouse base and a deck base, which are connected to the ship's deck using assembly screws. This allows for flexible and simple assembly and disassembly, with high efficiency, thus minimizing the impact on the ship's construction schedule. The central positioning sockets and positioning connecting posts ensure the relative position accuracy of the deckhouse base and deck base when assembled. This ensures the deckhouse's position on the ship's deck is accurately maintained during the temporary removal and restoration of the deckhouse during multiple bridge crossings. This allows the deckhouse to be effectively restored to its original state after a successful bridge crossing. Furthermore, this detachable base eliminates the need for cutting and welding to restore the deckhouse, effectively avoiding the safety hazards associated with existing methods.

[0017] In order to further understand the content, features and effects of the present invention, the following embodiments are given to illustrate in detail.

[0018] See Figure 1 and Figure 2 The detachable ship deckhouse base of the utility model includes a deckhouse base installed and fixed on the bottom of the deckhouse 1 and a deck base arranged on the ship deck 5. The deckhouse base, the deck base and the ship deck 5 are detachably connected.

[0019] Typically, each deckhouse 1 is supported by four sets of deckhouse and deck mounts located at the four corners of the base. Because the deckhouse and deck mounts can be disassembled and easily assembled with the ship's deck 5, the deckhouse 1 and the ship's deck 5 can be flexibly and conveniently disassembled and reassembled. The deckhouse mounts are fixed to the bottom of the deckhouse 1, so they move synchronously with the deckhouse 1 during disassembly, transfer, and reassembly. There is no fixed connection between the deck mounts and the ship's deck 5.

[0020] The deckhouse base comprises an upper base 2, the top of which is fixedly connected to the bottom of the deckhouse 1, and a lower base 9 mounted and fixed below the upper base 2. A positioning socket 3, which does not extend upward, is provided at the center of the lower base 9. The deck base comprises a plate base 4 and a positioning connecting column 7 mounted and fixed in the middle of the plate base 4. The deckhouse base is stacked on top of the deck base, and the positioning connecting column 7 is inserted into the positioning socket 3.

[0021] The purpose of providing the positioning sockets 3 and the positioning connecting posts 7 is to ensure accurate positioning of the deckhouse base and deck base when they are stacked and assembled, by inserting the positioning connecting posts 7 into the positioning sockets 3. In this embodiment, the bottom of the positioning sockets 3 is open, and the top of the positioning connecting posts 7 is tapered. The inner diameter of the positioning sockets 3 is equal to the outer diameter of the positioning connecting posts 7. The open bottom of the positioning sockets 3 and the tapered top of the positioning connecting posts 7 make it easier to insert the positioning connecting posts 7 upward, providing a certain centering effect.

[0022] In this embodiment, the bottom upper base 2 includes a vertical middle support plate 2-1 and side reinforcement plates 2-2 welded and installed on both sides of the middle of the middle support plate 2-1. The length dimension of the top edge of the middle support plate 2-1 is significantly larger than the length dimension of the bottom edge. The top edges of the middle support plate 2-1 and the side reinforcement plates 2-2 are welded and fixed to the bottom of the deckhouse 1, and the bottom edges of the middle support plate 2-1 and the side reinforcement plates 2-2 are welded and fixed to the top of the bottom lower base 9.

[0023] In this embodiment, a vertically penetrating center hole 8 is provided in the middle of the plate base 4 , and the lower portion of the positioning connecting column 7 is inserted into the upper portion of the center hole 8 and fixed by welding.

[0024] There are multiple threaded holes at the bottom of the bottom lower base 9, and multiple connection holes are provided at corresponding positions on the plate base 4 and the ship deck 5. The bottom lower base 9, the plate base 4 and the ship deck 5 are fixedly connected by multiple assembly screws 6.

[0025] In this embodiment, a rubber sealing gasket 10 is provided between the bottom lower base 9 and the plate base 4. Similarly, it is conceivable that a rubber sealing gasket 10 may also be provided between the plate base 4 and the ship deck 5. The purpose of providing the rubber sealing gasket 10 is to seal the joint. Under the action of pressure, the rubber sealing gasket 10 deforms and closes the gaps between the bottom lower base 9 and the plate base 4, and between the plate base 4 and the ship deck 5, thereby preventing external rainwater from entering through the gaps between adjacent components, causing rust and deck leakage.

[0026] Operation method:

[0027] Figure 1The figure shows the normal installation state of the deckhouse 1 on the ship deck 5. When the deckhouse 1 needs to be temporarily disassembled and transferred due to height restrictions when crossing the bridge, the assembly screws 6 are removed in the cabin below the ship deck 5. The deckhouse 1 is then lifted upward by a crane, and the deckhouse base, deck base, and ship deck 5 are completely separated. The main body of the ship then passes under the bridge, and the deckhouse 1 is lifted and transferred to pass over the bridge or to an auxiliary vessel to pass under the bridge.

[0028] After the ship completes crossing the bridge, the deckhouse 1 is installed and restored. Specifically, the four plate bases 4 are first placed at the positions of the four groups of connecting holes on the ship deck 5, and the assembly screws 6 are inserted into the groups of connecting holes on the ship deck 5 and the plate bases 4 from bottom to top in the cabin below the ship deck 5. Then, the position of each deck base is determined and a rubber sealing gasket 10 is set; then the deckhouse 1 is hoisted to the top of the ship deck 5, and the position of the deckhouse 1 is moved with the assistance of the personnel on the deck until the four deckhouse bases at its bottom are respectively located directly above the four deck bases; then the deckhouse 1 is slowly lowered, and when the deckhouse base is superimposed on the deck base, the positioning connecting column 7 is inserted upward into the inside of the positioning socket 3 until the bottom lower base 9 is completely superimposed on the rubber sealing gasket 10 and the hoisting cable of the crane is loosened, and then each assembly screw 6 is tightened from the cabin below until it reaches Figure 1 The status shown in .
