Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, specifically to an integrated structure and manufacturing method of a marine railing and a refrigerated socket box base. Background Technology

[0002] In shipbuilding, areas such as ship passageways and decks typically require the installation of various functional equipment, such as socket boxes for refrigerated containers. This equipment requires stable bases for secure installation, and for safety reasons, these areas are generally equipped with guardrails. In existing conventional ship designs, the equipment bases and guardrails are often two independent parts, designed and installed as two separate structural units. This traditional separate design approach has many shortcomings in practice: independent bases are usually heavy, have many welding points, and have long construction periods; they also experience significant vibration during ship operation, occupy a large area, and have poor aesthetics.

[0003] The separately designed equipment bases and railing systems each require their own supporting structures, such as supports and elbows, resulting in redundant overall structures and numerous components. This not only increases material costs but also creates multiple protrusions or obstacles in the already limited ship passageways or deck space, occupying valuable usable space and sometimes even affecting personnel passage or equipment layout. Moreover, ships are continuously subjected to complex vibrations and impacts caused by wind, waves, main engines, propellers, etc., during navigation. Independent equipment bases, especially ground-mounted bases with relatively simple supporting structures, may have their natural frequencies easily coupled with the ship's vibration frequencies, resulting in large amplitudes during operation. Over the long term, this can easily lead to welding fatigue cracks or structural loosening, threatening the safe and stable operation of the equipment. At the same time, it is difficult to meet the high strength and high stability requirements of some ships for critical equipment bases.

[0004] The separately designed equipment bases and railings require two separate measurements, positioning, welding, and painting processes, resulting in a complex construction workflow and a large amount of welding work. This not only increases labor costs and working hours, extending the construction cycle, but also places higher demands on construction precision and quality control due to the extensive on-site welding work, increasing construction difficulty and the risk of errors. Furthermore, the separately designed bases and railings often lack a unified design in form, with the bases standing abruptly on the deck or close to the railings, disrupting the overall smooth lines and aesthetics of the ship's superstructure, giving a piecemeal and uncoordinated visual impression, and failing to meet the increasingly demanding aesthetic requirements of modern ships' interior spaces. Due to the dispersed structure, pipeline layouts, such as cable conduits, may need to meander between the base and railing structures, increasing wiring complexity. During later maintenance, repairs to any structure may involve adjacent structures, limiting maintenance work space and making operations inconvenient.

[0005] Therefore, there is an urgent need in this field for an innovative design that can fundamentally solve the above problems, achieve the organic integration of the equipment base and railing functions, and thus achieve significant improvements in terms of ensuring structural strength, simplifying construction, saving space and enhancing aesthetics. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an integrated structure and manufacturing method for a marine railing and a refrigerated socket box base. By integrating the refrigerated socket box base and the railing into a single design, the invention solves the problems of structural redundancy, large vibration, complex construction and high cost, poor aesthetics and inconvenient maintenance caused by the separate installation of the equipment base and the railing in the traditional method. The integrated railing and refrigerated socket box base achieves significant improvements in terms of saving space, improving structural strength and stability, simplifying construction, reducing costs, improving aesthetics and making maintenance more convenient.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0008] This invention first provides an integrated structure of a marine railing and a refrigerated socket box base, which includes a base part and a support part. The upper end of the support part is connected to the top hull structure, the lower end of the support part is connected to the bottom hull structure, the two sides of the support part are connected to the walkway railing, and the base part is connected to the middle part of the support part. The base part supports the refrigerated socket box, and the base part and the support part form an integral structure and serve as part of the walkway railing.

[0009] The base includes a base panel, a grounding post, and a cable clamp. The base panel has multiple screw holes for installing the refrigerated socket box. The support includes angle steel support columns and reinforcing angle steel.

[0010] The angle steel support columns include two upper angle steel support columns and two ground angle steel support columns. The upper end of the base panel is perpendicularly connected to the two upper angle steel support columns, and the lower end of the base panel is perpendicularly connected to the two ground angle steel support columns. The upper end of the upper angle steel support columns is connected to the top hull structure, and the lower end of the ground angle steel support columns is connected to the bottom hull structure. The upper angle steel support columns and the ground angle steel support columns correspond one-to-one and are aligned in a straight line. Reinforcing angle steel is perpendicularly connected between the two ground angle steel support columns.

[0011] The cable conduit is clamped on a reinforcing angle steel, and a grounding post is provided at the lower end of the base panel.

[0012] In the integrated structure of a marine railing and a refrigerated socket box base of the present invention, the base panel is a rectangular frame structure welded from 4 angle steels, and there are 6 screw holes on the base panel.

[0013] In the integrated structure of a marine railing and refrigerated socket box base of the present invention, the angle steel support column and the base panel are connected by welding.

[0014] In the integrated structure of a marine railing and a refrigerated socket box base of the present invention, the supporting part further includes an angle steel brace. One end of the angle steel brace is connected to one side of the upper angle steel support column, and the other end of the angle steel brace is connected to the top hull structure. The plane where the angle steel brace and the upper angle steel support column are located is perpendicular to the plane where the base panel is located.

[0015] In the integrated structure of a marine railing and refrigerated socket box base of the present invention, the angle steel brace includes two mutually perpendicular rectangular plates. One plate has 45° beveled edges cut along the midpoint of the two plates at both ends. Each end of the plate with the beveled edges has a 4mm wide arc groove. A trapezoidal plate is slidably connected to each arc groove. A 4mm diameter column is vertically welded to the trapezoidal plate, and the column on the trapezoidal plate is inserted into the arc groove. The lower arc groove corresponds to... The back of the angle steel brace is marked with graduations, and the tip of the trapezoidal plate is connected to the tip of the end of the angle steel brace. When the column of the lower trapezoidal plate is at one end of the arc groove near the middle boundary line of the two plates of the angle steel brace, the trapezoidal plate coincides with the angle steel brace, and the included angle between the angle steel brace and the upper angle steel support column is 45°. When the column of the lower trapezoidal plate is at the other end of the arc groove, the included angle between the angle steel brace and the upper angle steel support column is 70°. The upper end face of the upper trapezoidal plate is in contact with the top hull structure.

[0016] In the integrated structure of a marine railing and a refrigerated socket box base of the present invention, there are 3 reinforcing angle steels, 1 reinforcing angle steel is vertically welded between the 2 upper angle steel support columns, and 2 reinforcing angle steels are vertically welded between the 2 lower angle steel support columns.

[0017] In the integrated structure of a marine railing and refrigerated socket box base of the present invention, the cable clamp is welded to the reinforcing angle steel located in the middle, and the cable clamp faces the inside of the ship's interior.

[0018] In the integrated structure of a marine railing and a refrigerated socket box base of the present invention, railing hooks are welded on both sides of the angle steel support column. The railing hooks appear in pairs and correspond to the reinforcing angle steel. The railing hooks and the corresponding reinforcing angle steels are welded to the same horizontal plane. The chain on the walkway railing is hung on the railing hooks.

[0019] In the integrated structure of a marine railing and a refrigerated socket box base of the present invention, one side of the ground angle steel support column is also welded with angle steel diagonal bracing, and the other end is connected to the bottom hull structure. The base panel, upper angle steel support column, ground angle steel support column, angle steel diagonal bracing, and reinforcing angle steel are all made of marine structural steel.

[0020] This invention also provides a method for manufacturing an integrated structure of marine railing and refrigerated socket box base. This method utilizes the aforementioned integrated structure of marine railing and refrigerated socket box base, and includes the following steps:

[0021] Step 1: Prefabricate the base panel. Select four angle steels of appropriate size according to the equipment size and weld them into a rectangular frame structure base panel. Make screw holes on the base panel according to the equipment size.

[0022] Step 2: Weld the initial support frame. Weld one reinforcing angle steel vertically between two upper angle steel support columns, and weld two reinforcing angle steels vertically between two ground angle steel support columns.

[0023] Step 3: Weld the connection structure with the walkway railing. Weld the railing hooks symmetrically to both sides of the ground angle steel support column, and make them on the same horizontal plane as the corresponding reinforcing angle steel.

[0024] Step 4: Weld the panel and the support frame to form the base assembly. Vertically weld the lower ends of the two upper angle steel support columns to the upper end of the base panel, and vertically weld the upper ends of the two lower angle steel support columns to the lower end of the base panel.

[0025] Step 5: Weld and fix the base assembly to the hull structure. Determine the welding angle between the angle steel brace and the upper angle steel support column, as well as the welding position of the angle steel brace on the upper angle steel support column, according to the actual situation. Slide the column on the lower trapezoidal plate in the corresponding arc groove to meet the welding angle requirements. Then weld and fix the trapezoidal plate to the angle steel brace. Weld one end of the angle steel brace, which has been welded to the trapezoidal plate, to the upper angle steel support column. Slide the column on the upper trapezoidal plate to the appropriate position in the corresponding arc groove according to the actual situation and weld the trapezoidal plate to the angle steel brace. Further weld it to the top hull structure. According to the requirements of the corresponding hull structure, add angle steel braces to the ground angle steel support column and weld the other side to the bottom hull structure. Hang the railing hook on the chain on the walkway railing of the hull.

[0026] Step 6: Weld the grounding post and cable clamp. Weld the grounding post to one side of the bottom of the base panel, and weld the cable clamp to the reinforcing angle steel according to the position of the cable pipe.

[0027] Step 7: Secure the refrigerated socket box. Use screws to pass through the screw holes and fix the refrigerated socket box to the base panel made in the above steps. Fix the cable of the refrigerated socket box to the cable clamp. Connect the grounding terminal on the refrigerated socket box body to the grounding post through the grounding wire to ensure that the refrigerated socket box is safely grounded.

[0028] Based on the above technical solution, the integrated structure and manufacturing method of the marine railing and refrigerated socket box base of the present invention, after practical application, has the following technical advantages compared with the traditional separate and independent setting of the refrigerated socket box base and railing:

[0029] 1. This invention integrates the base and railing into a single design, making the base part of the railing and fully utilizing the unused space on the railing as the base. This enables the railing to support equipment and achieves the integration of the base and railing into a single structure and function. This avoids the need to set up a separate base in places such as deck passages, thereby maximizing the release of valuable deck walking and working space and solving the problem of traditional bases taking up too much space.

[0030] 2. This invention utilizes angle steel support columns, reinforcing angle steel, and welded angle steel diagonal braces to create a stable structure. This design rigidly connects the equipment base to the ship's hull structure, such as railings, forming a unified load-bearing unit. This significantly improves the overall rigidity, anti-overturning capacity, and structural stability of the base. The structure effectively disperses and absorbs continuous vibrations and accidental impacts during ship navigation, greatly reducing the risk of fatigue damage to the equipment and its connecting components, ensuring the reliability and safety of the refrigerated socket box during long-term operation in harsh sea conditions. Simultaneously, a specially designed grounding post is welded to the base panel, providing a direct and reliable grounding channel for the refrigerated socket box, effectively preventing leakage risks and complying with stringent marine electrical safety regulations. Furthermore, integrating cable clamps welded to the central reinforcing angle steel ensures neat and orderly cable routing, preventing messy exposed wiring and further optimizing the spatial appearance and operational safety.

[0031] 3. This invention combines the previously separate railings and bases into a single integrated component, achieving one-time positioning and overall welding. This significantly reduces the number of welding operations and total working hours on board, simplifies the construction process, reduces construction difficulty, and effectively shortens the shipbuilding cycle. The integrated design also avoids redundant structural supports, reduces redundant steel usage, achieves structural lightweighting, and helps reduce the ship's empty weight. Furthermore, the clear structure and high degree of component standardization facilitate routine inspection, maintenance, and potential equipment replacement, improving construction and maintenance efficiency and enhancing the overall economic benefits throughout the ship's lifecycle.

[0032] 4. This invention achieves seamless connection and smooth transition between the equipment base and the ship railing system, eliminating the structural abruptness and visual disharmony caused by traditional separate designs, making the ship deck appearance simpler, smoother and more beautiful, and improving the overall industrial design level of the ship.

[0043] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the integrated structure and manufacturing method of the marine railing and refrigerated socket box base of the present invention, in order to more clearly understand its structural composition and working principle, but this should not be construed as limiting the scope of protection of the present invention.

[0044] The improvement of this invention addresses the problems of heavy base weight, numerous welding points, long construction period, large vibration during ship operation, large footprint, and poor aesthetics caused by the separate design of the refrigerated socket box base and the ship railing. It proposes an integrated design concept for the refrigerated socket box base and the ship railing, achieving functional integration and optimization through structural innovation.

[0045] Example 1

[0046] like Figure 1 , Figure 2 The embodiment described herein is an integrated structure of a marine railing and a refrigerated socket box base, comprising a base portion and a support portion. The upper end of the support portion is connected to the top hull structure, the lower end of the support portion is connected to the bottom hull structure, and the two sides of the support portion are connected to walkway railings. The base portion is connected to the middle part of the support portion and is used to support the refrigerated socket box. The base portion and the support portion form an integral structure and serve as part of the walkway railing, thus forming an integrated structure of a marine railing and a refrigerated socket box base.

[0047] The base includes a base panel 3, a grounding post 5, and a cable clamp 9. The base panel 3 has multiple screw holes 4. The position of the screw holes is determined according to the size of the refrigerated socket box to be installed. The support part includes an angle steel support column and a reinforcing angle steel 8.

[0048] The angle steel support column includes two upper angle steel support columns 2 and two ground angle steel support columns 6. The upper angle steel support columns 2 are parallel to each other, and the ground angle steel support columns 6 are parallel to each other. The upper angle steel support columns (2) and the ground angle steel support columns (6) correspond one-to-one. The upper angle steel support columns 2 and the corresponding ground angle steel support columns 6 are on a straight line.

[0049] The upper end of the upper angle steel support column 2 is connected to the top hull structure, the lower end of the upper angle steel support column 2 is connected to the upper end of the base panel 3, one end of the angle steel brace 1 is connected to one side of the upper angle steel support column 2, and the other end of the angle steel brace 1 is connected to the top hull structure.

[0050] The upper end of the ground-mounted angle steel support column 6 is connected to the lower end of the base panel 3, and the lower end of the ground-mounted angle steel support column 6 is connected to the bottom hull structure.

[0051] Multiple reinforcing angle steels 8 are provided, and these reinforcing angle steels 8 are parallel to each other. The reinforcing angle steels 8 are vertically connected between the ground-level angle steel support columns 6. Whether the reinforcing angle steels 8 are vertically connected between the upper angle steel support columns 2 is determined according to specific circumstances. For example... Figure 9 As shown, the reinforcing angle steel 8 in the structure of the present invention can also be replaced with solid round steel, and the diameter of the solid round steel can be freely selected as needed.

[0052] The base panel 3, upper angle steel support column 2, ground angle steel support column 6, and reinforcing angle steel 8 are all on the same plane. The cable clamp 9 is installed on the reinforcing angle steel 8. A grounding post 5 is also provided at the lower end of the base panel 3. The grounding post 5 is welded to an appropriate position on the base panel 3, usually located at the edge of the base panel and facing downwards, so as to facilitate connection with the grounding terminal on the refrigerated socket box body through a grounding wire, so that the refrigerated socket box is safely grounded. The grounding post is made of a metal material with good conductivity to ensure the safe grounding of the refrigerated socket box, which complies with the marine electrical safety regulations.

[0053] The base panel 3 is a rectangular frame structure welded from four angle steels, and there are six screw holes 4 on the base panel 3. The hollow, lightweight design eliminates the need for a welded panel in the middle, reducing the overall weight of the base without affecting the stability of the overall structure. Furthermore, the hollow design makes it more versatile for some cold storage units with back-mounted wiring. The size of the base panel can be adjusted according to actual installation needs. Six screw holes are pre-drilled on the base panel according to the installation dimensions of the refrigerated socket box for securing it.

[0054] Two upper angle steel support columns 2 are vertically welded to the upper end face of the base panel 3, and two lower angle steel support columns 6 are vertically welded to the lower end face of the base panel 3. The height of the angle steel support columns can be adjusted according to the equipment height and its installation requirements to ensure that the base is installed stably and at an appropriate height.

[0055] The supporting part also includes an angle steel brace (1), one end of which is connected to one side of the upper angle steel support column (2), and the other end of which is connected to the top hull structure; the plane where the angle steel brace (1) and the upper angle steel support column (2) are located is perpendicular to the plane where the base panel is located, the welding angle of the angle steel brace (1) is adjustable, and the included angle between the angle steel brace (1) and the upper angle steel support column (2) is in the range of 45°-70°.

[0056] like Figure 3 , Figure 4 , Figure 5As shown, the angle steel brace 1 includes two mutually perpendicular rectangular plates. One plate has two ends cut with a 45° angled bevel along the midpoint of the two plates. Each plate with the beveled bevel has a 4mm wide arc groove 10 at each end. A trapezoidal plate 11 is slidably connected to each arc groove 10. A 4mm diameter column 12 is vertically welded to the trapezoidal plate 11. The column 12 on the trapezoidal plate 11 is inserted into the arc groove 10. The back of the angle steel brace 1 corresponding to the lower arc groove 10 is engraved with... The "back side" refers to the back side of the angle steel brace 1 connected to the trapezoidal plate. A scale corresponding to the angle between the angle steel brace 1 and the upper angle steel support column 2 is set on the back side next to the arc groove. The scale range is 45°-70°. For example, when the angle between the angle steel brace 1 and the upper angle steel support column 2 is 60°, the column 12 is exactly aligned with the scale of 60°. Therefore, after determining the required welding angle, the sliding position of the lower column in the corresponding arc groove can be quickly determined according to the scale without the need for re-measurement, resulting in higher welding efficiency.

[0057] like Figure 6 , Figure 7 As shown, the pointed end of the trapezoidal plate 11 connects to the pointed end of the angle steel brace 1. When the column 12 of the lower trapezoidal plate 11 is at one end of the arc groove 10 near the midpoint of the two plates of the angle steel brace 1, the trapezoidal plate 11 coincides with the angle steel brace 1, and the included angle between the angle steel brace 1 and the upper angle steel support column 2 is 45°. When the column 12 of the lower trapezoidal plate 11 is at the other end of the arc groove 10, the included angle between the angle steel brace 1 and the upper angle steel support column 2 is 70°. The upper surface of the upper trapezoidal plate 11 fits against the top hull structure. The upper trapezoidal plate 11 is used to compensate for the height difference with the top hull structure and to increase the welding area. Specifically, the size and shape of the trapezoidal plate 11 at the upper end can be determined based on factors such as the angle between the angle steel brace and the upper angle steel support column, the shape of the top hull structure, and the distance between the plate and the top hull structure. This also determines whether the column needs to be adjusted by sliding in the corresponding arc groove. This adjustment can compensate for the height difference with the top hull structure within a certain range, or it can adjust the trapezoidal plate to increase the welding surface with the top hull structure, ensuring a complete fit between its upper surface and the top hull structure for a stronger weld. By sliding the column 12 on the trapezoidal plate 11 in the arc groove 10, welding the angle steel brace 1 and the trapezoidal plate 11 at different angles is achieved, thereby adjusting the welding angle between the angle steel brace 1 and the upper angle steel support column 2. The design of the angle steel brace 1 further enhances the stability of the base, while the adjustment of the welding angle ensures that the angle steel brace 1 achieves optimal reinforcement and provides the best support effect, especially when encountering significant vibrations during ship operation, effectively reducing overall structural sway.

[0058] There are three reinforcing angle steels 8. One reinforcing angle steel 8 is vertically welded between the two upper angle steel support columns 2, and two reinforcing angle steels 8 are vertically welded between the two lower angle steel support columns 6. The three reinforcing angle steels 8 are welded between the angle steel support columns to form a stable rectangular reinforced frame structure.

[0059] The cable clamp 9 is welded to the reinforcing angle steel 8 located in the middle. The cable clamp 9 faces the inside of the ship's interior, and its specific position is determined according to the cable route. The cable clamp is used to fix the cables of the refrigerated socket box equipment. The number and position of the cable clamps can be flexibly arranged according to the cable route to ensure that the cables are neat and safe, and to avoid cable wear or detachment due to ship vibration.

[0060] The angle steel support column is also welded with railing hooks 7 on both sides. There are an even number of railing hooks 7, appearing in pairs. Each pair of railing hooks 7 is welded to the corresponding reinforcing angle steel 8 on the same horizontal plane. Figure 8 , 9 As shown, the chain on the walkway railing is hung on the railing hook 7. In this embodiment, four railing hooks 7 are symmetrically arranged on both sides of the base and connected to the grounding angle steel support column by welding. The number of railing hooks can also be adjusted to six, that is, three pairs of railing hooks are symmetrically arranged on both sides of the base. Three reinforcing angle steels 8 are respectively located on the same horizontal plane as the three pairs of railing hooks 7, further enhancing the stability of the overall structure.

[0061] Angle steel bracing 1 is also welded to one side of the ground-mounted angle steel support column 6, and its other end is connected to the bottom hull structure. Sometimes the base is set at a corner of a ship with a special irregular shape. In this case, angle steel bracing 1 is added to the lower part of the overall base to further enhance the stability of the base. The base panel 3, upper angle steel support column 2, ground-mounted angle steel support column 6, angle steel bracing 1, and reinforcing angle steel 8 are all made of marine structural steel, and their surfaces are treated with rust and corrosion prevention. This is to adapt to the harsh environment of ships, such as humidity and salt spray. The welding process complies with ship welding specifications, and necessary rust and corrosion prevention treatments are carried out after welding to extend service life.

[0062] This integrated structure, as a functional module, structurally combines equipment installation with the support and protection functions of ship railings. Once the refrigerated socket box is installed on the base panel, its weight and vibrations generated during operation are effectively transmitted and absorbed through the triangular support system formed by the angle steel support columns and angle steel diagonal braces 1. The reinforcing angle steel 8 further constrains the relative displacement of the support columns, preventing structural deformation and thus ensuring the long-term stable operation of the equipment in the harsh marine environment.

[0063] In this embodiment, all welded connections, especially the welds between the angle steel support column and the base panel 3, and the welds between the angle steel support column and the hull structure, adopt a continuous full welding process to ensure the strength of the connection and the structural requirements.

[0064] Example 2

[0065] This embodiment describes a method for manufacturing an integrated structure of a marine railing and a refrigerated socket box base. This embodiment utilizes the integrated marine railing and refrigerated socket box base from Embodiment 1 to achieve the installation operation of the integrated marine railing and refrigerated socket box base, including the following steps:

[0066] Step 1: Prefabricate the base panel: Select four angle steels of appropriate size according to the equipment size and weld them together to form a rectangular frame structure base panel 3, and accurately drill screw holes 4 on the base panel 3 according to the equipment size.

[0067] Step 2: Weld the supporting and reinforcing structures to form a preliminary support frame: Weld one reinforcing angle steel 8 vertically between two upper angle steel support columns 2, and weld two reinforcing angle steel 8 vertically between two ground angle steel support columns 6.

[0068] Step 3: Weld the railing hooks to facilitate connection with the walkway railing: Symmetrically weld the railing hooks 7 to both sides of the ground-mounted angle steel support column 6, ensuring they are on the same horizontal plane as the corresponding reinforcing angle steel 8;

[0069] Step 4: Weld the panel to the supporting structure to form the base assembly: Weld the lower ends of the two upper angle steel support columns 2 vertically to the upper end of the base panel 3, and weld the upper ends of the two lower angle steel support columns 6 vertically to the lower end of the base panel 3.

[0070] Step 5: Weld and fix the base assembly to the ship's hull deck and other structures according to the design position: Weld the structure made in the above steps to the ship's hull structure. Determine the welding angle between the angle steel brace 1 and the upper angle steel support column 2, as well as the welding position of the angle steel brace 1 on the upper angle steel support column 2, based on the weight of the equipment and the corresponding ship structure at the installation position. Slide the column 12 on the lower trapezoidal plate 11 in the arc groove 10 of the angle steel brace 1 to meet the welding angle requirements. Then weld and fix the trapezoidal plate 11 to the angle steel brace 1. Weld this end of the angle steel brace 1, which has been welded to the trapezoidal plate 11, to the upper angle steel support column 2. Slide the column of the upper trapezoidal plate in the corresponding arc groove according to the actual situation to the appropriate position. The trapezoidal plate is positioned and welded to the angle steel brace and further welded to the top hull structure. The actual situation here refers to determining the sliding position of the column of the trapezoidal plate near the top hull structure in the corresponding arc groove based on factors such as the distance from the top hull structure, the inclination and shape of the top hull structure; and according to the requirements of the corresponding hull structure, angle steel brace 1 is added to the ground angle steel support column 6 and welded to the bottom hull structure on the other side. The railing hook 7 is hung on the chain on the walkway railing of the hull; ensure that all welding quality meets the strength requirements of the ship structure. Generally, the welding position of the angle steel brace 1 on the upper angle steel support column 2 can be determined according to the shape of the top hull structure and its distance.

[0071] Step 6: Weld the grounding post to facilitate grounding of the refrigerated socket box equipment, and install cable clamps to fix the cable pipe: Weld the grounding post 5 to the bottom of the base panel 3 near one side, and weld the cable clamp 9 to the reinforcing angle steel 8 according to the position of the cable pipe 9.

[0072] Step 7: Connect and fix the refrigerated socket box to the integrated structure made in the above steps: Use screws to pass through screw holes 4 to fix the refrigerated socket box to the base panel made in the above steps, fix the cable of the refrigerated socket box to the cable clamp 9, and connect the grounding terminal on the refrigerated socket box body to the grounding post 5 through the grounding wire to achieve safe grounding of the refrigerated socket box.

[0073] By integrating the railing with the refrigerated socket box base, not only is passageway space significantly saved and the aesthetics of the ship improved, but construction complexity and material costs are also greatly reduced. The overall structure has high strength and good vibration resistance, making it suitable for walkways and equipment installation areas on various types of ships.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
