Description

Technical Field

[0001] The present invention relates to the field of shipbuilding, and in particular to a unitary detachable ship cab and a construction method thereof. Background Art

[0002] The ship cab is a centralized place for ship operation, and its mode and layout are determined during ship design. During shipyard construction, the cab can utilize the shipyard's complete facilities and construction process to complete work such as hoisting, insulation laying, equipment installation, and interior fitting. After completion and leaving the factory, except in the case of major renovations, it generally cannot be demolished and renovated. If major renovations are required, it is necessary to return to the factory or select another shipyard / repair shipyard and use equipment for renovation. At this time, related work such as the original insulation laying, equipment installation, and interior fitting may increase the renovation work. In traditional shipbuilding processes, the ship cab is usually fixed to the bridge deck by welding. Although this fixing method ensures the stability of the cab to a certain extent, it also brings some problems:

[0003] Firstly, welding operations during the assembly of the cab section will inevitably damage the insulation / heat insulation materials under the bridge deck. To prevent this damage, during the construction process, it is often necessary to first complete construction processes that may cause damage such as the assembly welding of the cab section, and then carry out the construction of the insulation / heat insulation materials. However, when the shipyard adopts sectional construction and the assembly is carried out in different locations (especially in enclosed waters such as inland lakes and reservoirs without waterway connections), this construction sequence will result in the inability to complete pre - process operations such as insulation / heat insulation materials during the sectional construction in the shipyard, thus increasing the processes, time, and cost of off - site construction. In addition, such off - site construction activities will also cause a certain degree of damage to the water quality of the protected waters and the environment on the water's edge.

[0004] Secondly, when renovating the fixed - welded cab, it is necessary to completely demolish the interior fittings, equipment, and other facilities inside the cab, and high - heat cutting means such as acetylene, plasma, and laser are required during the cutting process. This will not only further damage the insulation / heat insulation materials but also require their repair during the renovation process, thus significantly increasing the renovation cycle and cost. Summary of the Invention

[0005] The invention objective of the present invention is, in view of the above problems, to provide a unitary detachable ship cab and a construction method thereof, so as to install the ship cab on the bridge deck by detachable means, improve the construction efficiency and transformability of the ship cab, and at the same time reduce the negative impact on the hull materials and the environment.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] In a first aspect, the present invention provides a unitary detachable ship's cab, comprising a driving deck and a cab. The cab is detachably mounted on the driving deck. The cab includes a cab bulkhead enclosing an internal space. A mating seat is fixedly provided at the bottom surface of the cab bulkhead. A mating base corresponding to the mating seat is fixedly provided at the top surface of the driving deck. The mating base is docked and installed with the mating seat through fasteners, and the mating base and the mating seat can be installed towards the inside or outside of the cab.

[0008] As a preferred embodiment, the mating seat includes an upper panel which is horizontally arranged and perpendicular to the cab bulkhead, and the top surface of the upper panel is fixedly connected to the bottom of the cab bulkhead.

[0009] As a preferred embodiment, the mating seat further includes an upper bracket which is arranged perpendicular to both the cab bulkhead and the upper panel, and its adjacent two side edges are respectively fixedly connected to the wall surface of the cab bulkhead and the top surface of the upper panel to enhance the connection strength between the upper panel of the mating seat and the cab bulkhead. It should be noted that the upper bracket can be selectively added according to the installation orientation of the mating seat.

[0010] As a preferred embodiment, the mating base includes a web, a lower panel and a lower bracket. The web is perpendicular to the driving deck and its bottom surface is fixedly connected to the top surface of the driving deck. The lower panel is horizontal relative to the upper panel and its bottom surface is fixedly connected to the top surface of the web. The lower bracket is arranged perpendicular to both the web and the lower panel, and its adjacent two side edges are respectively fixedly connected to the side surface of the web and the bottom surface of the lower panel.

[0011] As a preferred embodiment, the fasteners include bolts and nuts that cooperate with the bolt knobs. Bolt holes for the bolts to pass through are correspondingly provided on the upper panel and the lower panel.

[0012] As a preferred embodiment, a sealing layer is clamped between the upper panel and the lower panel. The sealing layer can be made of rubber material or epoxy resin damping material to reduce vibration and ensure weathertightness.

[0013] As a preferred embodiment, a protective layer is provided on the outer periphery of the fasteners. The protective layer completely wraps the fasteners inside to protect the fasteners. The protective layer can be formed by filling with a foaming agent, which can avoid problems such as rust and breakage caused by the fasteners being soaked in water and enhance the service life.

[0014] In a second aspect, the present invention provides a construction method for a unitary detachable ship's cab, comprising the following steps:

[0015] S1. Prefabricate the driving deck in sections, preset the inspection waterline of the driving deck unit. After completing the manufacture of the driving deck section, first install the water retaining fence and the mating base on the driving deck. The height of the water retaining fence is < 150 mm, and the mating base surface is ensured to be horizontal. Then, complete the installation of the insulation / thermal insulation materials and cable laying under the driving deck according to the unit outfitting standard, and reserve standardized electrical / pipeline interfaces.

[0016] S2. Prefabricate the cab in sections, preset the inspection waterline of the cab unit. Leave a technological margin of 20 - 30 mm at the lower opening of the cab bulkhead. Then, according to the unit outfitting standard, complete the installation of the insulation / thermal insulation materials, cable laying and interior fitting inside the cab with the preset inspection waterline of the cab unit as the positioning reference, and reserve standardized joints corresponding to the electrical / pipeline interfaces of the driving deck section.

[0017] S3. Pre-assemble the cab unit and install the mating seat: Lift the cab unit onto the driving deck unit. First, adjust the relative position of the cab unit and the driving deck unit based on the difference between the preset inspection waterlines of the two units by using an electronic level, calculate the surplus value that needs to be cut, and then use a plasma or laser cutting machine to cut off the surplus to ensure that the mating seat installation surface is horizontal.

[0018] S4. Transport the driving deck unit and the cab unit to a remote site for docking and mating; specifically, first lay a sealing layer on the lower panel of the mating base; second, align the bolt holes of the upper panel and the lower panel of the mating seat concentrically, with a deviation ≤ ±1 mm, insert the bolts and tighten them in stages with a torque wrench; finally, dock the standardized joints of the cab with the standardized interfaces of the driving deck, add a waterproof sleeve at the interface docking part and lock it, connect the cable joints and test for conductivity.

[0019] S5. Manufacture the outdoor protective layer. Install a mold around the fasteners located outdoors. Preset a filling hole at the top of the mold. The mold, the driving deck, the web and the cab bulkhead enclose to form a filling cavity. Fill the cavity with foaming agent through the filling hole. After the foaming agent is cured and shaped, remove the mold.

[0020] The beneficial effects of the above technical solution provided by the present invention compared with the prior art are as follows:

[0021] The mating base of the driving deck and the mating seat of the cab of the present invention are mated and installed through bolts with a sealing layer, which not only significantly improves the mating efficiency, but also ensures the weathertightness of the mating part, avoids damage to the deck insulation / heat insulation materials or equipment caused by traditional welding operations, and is also convenient for quick disassembly and assembly during later maintenance or renovation, minimizing the damage to the ship caused by high-temperature cutting such as acetylene, plasma, and laser during disassembly and assembly. In the construction method, the driving deck and the cab are prefabricated in sections as independent units in the shipyard and then transported to another place for mating. The construction of front and rear processes such as insulation laying, cables, and interior decoration can be completed during sectional construction, greatly reducing the construction processes and time at the other place, and at the same time reducing the construction activities near relatively enclosed waters to protect the water quality and the surrounding environment of the waters.

[0036] In a first aspect, please refer to Figures 1-6 , the present invention provides a unitary detachable ship cab, which includes a driving deck 10 and a cab installed on the driving deck 10. The cab includes a cab bulkhead 20 that encloses an internal space and stiffeners for strengthening the bulkhead structure. The cab bulkhead 20 is specifically composed of a front bulkhead 21 (front side of the control console), a rear bulkhead 22, side bulkheads 23, and an inner bulkhead 24. A mating seat 30 is fixedly arranged on the bottom surface of the driving bulkhead 20, and a mating base 40 corresponding to the mating seat 30 is fixedly arranged on the top surface of the driving deck 10. The mating base 40 and the mating seat 30 are butt-mounted through fasteners 50.

[0037] Preferably, the closing seat 30 includes an upper panel 31 with a horizontal plate arrangement. The upper panel 31 is perpendicular to the cab bulkhead 20, and its top surface is welded and fixed to the bottom of the cab bulkhead 20. Additionally, the closing seat 30 may further include an upper gusset plate 32, which is arranged perpendicular to both the cab bulkhead and the upper panel, and its adjacent two side edges are respectively welded and fixed to the wall surface of the cab bulkhead 20 and the top surface of the upper panel 31, and is in the same section as the stiffener of the cab to enhance the connection strength between the upper panel of the closing seat and the cab bulkhead.

[0038] Preferably, the closing base 40 includes a web 41, a lower panel 42, and a lower gusset plate 43. The web 41 is perpendicular to the driving deck 10 and is welded and fixed to the driving deck 10 below it. The thickness of the web 41 can be the same as or slightly greater than the thickness of the cab bulkhead 20 by 1 - 2 mm, that is, the web 41 and the cab bulkhead 20 together form the side wall structure of the cab. The lower panel 42 is arranged horizontally opposite to the upper panel 31 (i.e., perpendicular to the web 41), and the bottom surface of the lower panel 42 is welded and fixed to the top surface of the web 41. The lower gusset plate 43 is arranged perpendicular to both the web 41 and the lower panel 42, and its adjacent two side edges are respectively welded and fixed to the side surface of the web 41 and the bottom surface of the lower panel 42, and is in the same section as the stiffener of the cab. Preferably, the height of the closing base 30 is 100 mm to 150 mm, and this height should be slightly higher than the indoor water retaining fence. On the one hand, the height of the closing base 30 should not be too high to avoid interfering with the hoisting and transportation of the driving deck 10 and its lower bulkhead segments. On the other hand, the height of the closing base 30 should not be too low to avoid indoor condensed water accumulating higher than the base surface, showing abnormal water seepage.

[0039] Preferably, the fastener 50 includes bolts and nuts, and the number of them can be set to multiple according to the perimeter of the closing seat 30. The upper panel 31 and the lower panel 42 are correspondingly provided with multiple bolt holes (bolt connection points) for the bolts to pass through. Thus, by passing multiple bolts through the bolt holes one by one and tightening them with nuts, the cab can be installed on the driving deck 10.

[0040] Regarding the installation of the closing seat 30 and the closing base 40, it can be specifically divided into two ways: facing indoors or facing outdoors, where:

[0041] Please refer to Figures 1-6, Method 1: The mating seat 30 of the front bulkhead 21 faces the outside, and the mating seats 30 of the rear bulkhead 22, side bulkheads 23, and inner bulkhead 24 all face the inside. In this method, except for the mating seat 30 of the front bulkhead 21, the mating seats 30 of the rear bulkhead 22, side bulkheads 23, and inner bulkhead 24 can only include the panel 31. That is, when installing the mating seat 30, the stiffener is arranged at the installation position of the upper bracket 32 (the stiffener and the upper bracket are in the same section), and the bottom of the stiffener is welded and fixed to the upper panel 31, which can reduce the parts of the upper bracket 32. Correspondingly, the mating bases 40 corresponding to the mating seats 30 of the rear bulkhead 22, side bulkheads 23, and inner bulkhead 24 are all installed facing the inside, where the lower bracket 43 is arranged between the indoor water retaining fence and the web 41. The mating seat 30 of the front bulkhead 21 and the corresponding mating base 40 are both installed facing the outside, so that the bolt connection points and the disassembly operation surface are located in the external space of the cab. During disassembly, the construction personnel can directly operate outside the cabin through the deck or side channel without entering the interior of the cab, avoiding spatial conflicts with the control console and avoiding touching the internal equipment, and enabling the overall removal of the cab without removing the control console. In addition, the mating seat 30 of the inner bulkhead 24 faces the inside to ensure the width of the aisle / stairway in the cab.

[0042] Please refer to Figure 1 , Figure 2 , Figures 5-8 , Method 2: The mating seat 30 of the inner bulkhead 24 faces the inside, and the mating seats 30 of the front bulkhead 21, rear bulkhead 22, and side bulkheads 23 all face the outside. In this method, the mating seats 30 of the front bulkhead 21, rear bulkhead 22, and side bulkheads 23 all facing the outside can avoid the interference of the indoor water retaining fence with the tightening / loosening of the connecting bolts, thus affecting the cab mating efficiency, and this method is more convenient for the construction personnel to operate and tighten the bolts.

[0043] Preferably, a flat strip-shaped sealing layer 60 is clamped between the upper panel 31 and the lower panel 42. The sealing layer 60 can be specifically made of rubber material and preset through holes corresponding to the bolt holes. Rubber materials such as natural rubber, nitrile rubber (NBR), or fluororubber, etc. The sealing layer 60 is directly clamped between the upper panel 31 and the lower panel 42 during assembly. In addition, in other alternative embodiments, the sealing layer 60 can be made of epoxy resin damping material and directly installed after being cast in place on site. Setting the sealing layer 60 can not only utilize the characteristics of its elastic deformation to absorb mechanical vibration and suppress resonance transmission, but also ensure the sealing performance of the installation location, avoiding the infiltration of rainwater, seawater, etc. from the installation location.

[0044] Preferably, a protective layer 70 is provided on the outer periphery of the fastener 50. The protective layer 70 completely covers the fastener 50 outside the cab. The protective layer 70 can be formed by filling with a foaming agent. The foaming agent has characteristics such as light weight, heat preservation, and heat insulation, and can further play a sealing role. Its outer surface is arranged to have a certain inclination or diversion shape, so that water can flow smoothly from the panel surface, avoiding water accumulation on the surface of the protective layer 70, protecting bolts, etc. from being soaked in water and accelerating rusting, improving the bolt connection strength and reliability, and enhancing the safety and service life of the cab.

[0045] In a second aspect, the present invention provides a construction method for a unitized detachable ship cab, which includes the following steps:

[0046] S1. Prefabricate the driving deck in sections. First, install a water retaining fence and a closing base on the driving deck. The height of the water retaining fence is < 150 mm. Then, complete the installation of insulation / heat insulation materials and cable laying under the driving deck according to the unit outfitting standard, and reserve standardized electrical / pipeline interfaces.

[0047] S2. Prefabricate the cab in sections. First, install a closing seat on the cab bulkhead. The thickness of the upper panel of the closing seat reserves a process margin of 20 - 30 mm. Then, complete the installation of insulation / heat insulation materials, cable laying, and interior decoration in the cab according to the unit outfitting standard, and reserve standardized joints corresponding to the electrical / pipeline interfaces of the driving deck section.

[0048] The above steps S1 and S2 can be constructed simultaneously according to the construction drawings corresponding to each section.

[0049] S3. Transport the driving deck unit and the cab unit to the assembly site for docking and closing. The specific steps are as follows:

[0050] First, lift the cab above the driving deck, check the installation surface of the closing seat with an electronic level, and use a plasma cutting machine to cut off the surplus to ensure the horizontalness of the installation surface of the closing seat. Secondly, lay a sealing layer on the lower panel of the closing base. Then, align the bolt holes of the upper panel and the lower panel of the closing seat concentrically, with a deviation ≤ ±1 mm, insert bolts and tighten them in stages with a torque wrench. Finally, dock the standardized joint of the cab with the standardized interface of the driving deck, add a waterproof sleeve at the interface docking part and lock it, connect the cable joints and test the conduction.

[0051] S4. Make an outdoor protective layer. Install a mold on the outer periphery of the fastener in the outdoor area. A filling hole is preset at the top of the mold. The mold, the driving deck, the web, and the cab bulkhead enclose a filling cavity. Then, fill the cavity with a foaming agent through the filling hole, and remove the mold after the foaming agent is cured and shaped.

[0052] As described above, the mating base of the driving deck of the present invention and the mating seat of the cab are mated and installed through bolts and a sealing layer, which not only significantly improves the mating efficiency, but also ensures the weathertightness of the mating part, avoids damage to the deck insulation / heat insulation materials or equipment caused by traditional welding operations, and is also convenient for quick disassembly and assembly during later maintenance or renovation, minimizing the damage to the ship caused by high-temperature cutting such as acetylene, plasma, and laser during disassembly and assembly. In the construction method, the driving deck and the cab are prefabricated in sections as independent units in the shipyard and then transported to other places for mating. The construction of the front and rear processes such as insulation laying, cables, and interior fittings can be completed during sectional construction, greatly reducing the construction processes and time in other places, and at the same time reducing the construction activities near relatively enclosed waters, protecting the water quality of the waters and the surrounding environment of the waters.

[0053] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
