Description

Technical Field

[0001] This utility model relates to the field of shipbuilding tooling technology, and in particular to a composite tooling tie beam device for the assembly and loading process of container ships. Background Technology

[0002] During the construction of large container ships, the transverse bulkheads in the cargo hold area need to maintain precise spacing during the assembly (mid-section joining) and dock final joining stages. In traditional processes, temporary supports and reinforcements are usually used to fix the transverse bulkheads. However, these temporary structures have a single function, only providing support and failing to provide safe passage for construction workers. Furthermore, they cannot be reused after dismantling, resulting in material waste and increased costs.

[0003] In addition, in the multi-level container platform area inside the cargo hold, a large amount of temporary scaffolding needs to be erected during construction to provide working platforms and access routes. This not only increases construction time and costs, but also poses certain safety hazards.

[0004] Therefore, there is an urgent need for a special device that can reliably fix the spacing between transverse bulkheads, serve as a safe construction passage, and be reusable and transferable to different construction areas. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a composite tooling tie beam device for the assembly and loading process of container ships. It solves the problems of the existing temporary support structure having a single function, not being reusable, and requiring a large amount of additional scaffolding. It is suitable for fixing the spacing of transverse bulkheads in the cargo hold area of ​​large container ships and building construction passages.

[0006] The purpose of this utility model is achieved as follows: A composite tooling tie beam device for the assembly and loading process of container ships includes: Main beam: As the core load-bearing component, the main beam is set horizontally; Connecting side plates: symmetrically arranged on the left and right sides of the main beam, used for fixed connection with the external structure; Sealing plates: installed at both ends of the main beam to seal the pipe openings and reinforce the end structure; Platform plate: laid and fixed above the main beam to form a stable walking platform; Platform kick feet: installed on both sides of the platform plate; Railings: Symmetrically arranged on both sides of the platform plate, with the bottom fixedly connected to the connecting side plate, together with the platform kick plate, forming a safety protection system.

[0007] A composite tooling beam-pulling device for the assembly and loading process of container ships, wherein the main beam is a circular steel pipe with a diameter ranging from 356 mm to 500 mm.

[0008] A composite tooling tie beam device for the assembly and loading process of container ships, wherein the platform kick is an L-shaped angle steel, one side of the platform kick is connected to the railing, and the other side is connected to the platform plate.

[0009] A composite tooling tie beam device for the assembly and loading process of container ships, wherein the bottom of the upright of the railing is fixedly connected to the connecting side plate.

[0010] A composite tooling tie beam device for the assembly and loading process of container ships, wherein bolt holes are provided on the connecting side plate for bolt connection to accommodate bolt connection with transverse bulkheads, thereby increasing the ease of assembly and disassembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) Functional integration: The two major functions of "fixed spacing" and "construction passage" are integrated into one, replacing the traditional single-function temporary support and a large amount of scaffolding, simplifying the construction site layout.

[0012] (2) Precision assurance: The rigid structure reliably fixes the spacing between the transverse bulkheads, effectively ensuring the construction accuracy of the cargo hold and preventing the precision deviation caused by bulkhead deformation.

[0013] (3) Safe and efficient: It provides standardized safety passages and work platforms, which significantly reduces the risk of high-altitude operations and improves construction efficiency.

[0014] (4) Reusable, cost-saving and efficiency-enhancing: The modular design is robust and can be reused multiple times in different ships and different parts of the same ship (such as the transverse bulkhead area and cargo hold step area), which greatly reduces the consumption and waste of temporary materials and lowers construction costs.

[0015] (5) Easy to install and disassemble: The structure is simple and can be quickly installed and disassembled by welding or bolting without affecting the construction progress of the main structure. Attached Figure Description

Example

[0021] See Figure 1-3 , Figure 1 A structural front view of this utility model has been drawn. As shown in the figure, this utility model provides a composite tooling tie beam device for the assembly and loading process of container ships, used to connect and fix two parallel transverse bulkheads during the assembly of the bulkhead sections and the loading stage in the dry dock. It includes: Main beam 1: As the core load-bearing component, it adopts a large-diameter steel pipe, preferably with a diameter of 426mm, to ensure sufficient structural rigidity and strength.

[0022] Connecting side plate 2: Symmetrically arranged on the left and right sides of the main beam 1, used for welding and fixing to the top structure of the transverse bulkhead (such as the transverse hatch coaming).

[0023] Sealing plate 3: Located at both ends of the main beam 1, used to seal the pipe openings and reinforce the end structure.

[0024] Platform plate 4: It is laid and fixed above the main beam 1 to form a stable walking platform.

[0025] Platform kick feet 5: Located on both sides of the platform plate 4, preferably made of angle steel (such as L50x50x5), to prevent tools and debris from falling.

[0026] Railing 6: Symmetrically arranged on both sides of the platform plate 4, with its bottom fixedly connected to the connecting side plate 2, forming a safety guardrail.

[0027] The composite tooling tie beam device of this utility model is rigidly connected to the two transverse bulkheads through the connecting side plates 2 at both ends, thereby accurately fixing the cargo hold spacing; at the same time, the platform with guardrails formed on its upper part provides a safe and convenient passage and working channel for construction personnel.

[0028] In this embodiment, the main beam 1 is a circular steel pipe, the diameter of which can be selected between 356mm and 500mm according to the actual load requirements.

[0029] In this embodiment, bolt holes can be pre-set on the connecting side plate 2 to accommodate bolt connections with the transverse bulkhead, increasing the ease of assembly and disassembly.

[0030] In this embodiment, the platform kick bar 5 and the railing 6 together constitute a complete edge protection system.

[0031] After the construction of the transverse bulkhead area is completed, the device of this utility model can be disassembled as a whole and transported to the multi-layer container platform area at the bow and stern of the cargo hold. It is then horizontally erected between the steps to fix the step spacing and provide personnel passage, thus achieving reuse.

[0032] The core function of the composite tooling tie beam device of this utility model is to rigidly fix the cargo hold spacing between the two transverse bulkheads, while also serving as a passageway for construction personnel.

[0033] Throughout the loading process, the composite tooling tie beam continues to serve to fix the cargo hold spacing and provide construction access. After the construction in the transverse bulkhead area is completed, the tie beam can be disassembled and transferred to areas with more container platforms inside the fore and stern cargo holds, where it can be installed laterally at multi-level steps to fix the step spacing and facilitate personnel access.

[0034] Working principle: During the transverse bulkhead installation phase, the composite tooling tie beam device of this utility model is installed between the two positioned transverse bulkhead sections. The composite tooling tie beam device of this utility model is installed on its top, such as at the transverse hatch coaming. The composite tooling tie beam device of this utility model includes a main beam, a platform plate, and railings. The main beam is made of steel pipe with a diameter of 426mm. Connecting side plates are provided on the left and right sides of the main beam. A platform plate is provided on the top of the main beam. Sealing plates are provided at the front and rear ends of the main beam. Railings are evenly distributed on both sides of the platform plate. The bottom of the railings is fixed to the connecting side plates. Platform kick feet are provided on both sides of the platform plate. The platform kick feet are L-shaped, with one side connected to the railing and the other side connected to the platform plate.

[0035] Specific implementation examples: The composite tooling tie beam device of this invention is applied in the cargo hold area of ​​large container ships.

[0036] 1. Structural composition: The main beam 1 is made of a Q235B seamless steel pipe with an outer diameter of 426mm and a wall thickness of 10mm. The length is customized according to the width of the cargo hold, for example, 15000mm.

[0037] Two connecting side plates 2 are welded along the length of the left and right sides of the main beam 1. The connecting side plates 2 are made of steel plates with a thickness of 12mm, and their dimensions (e.g., 300mm high and matching the length of the main beam) are sufficient to provide a stable welding surface.

[0038] Circular sealing plates 3 are welded to both ends of the main beam 1. The sealing plates 3 are made of 10mm thick steel plates.

[0039] Platform plate 4 is fully covered on the upper surface of the main beam 1. The platform plate 4 is made of 5mm thick patterned steel plate and is fixed to the main beam 1 by intermittent welding to play an anti-slip role.

[0040] Platform kick feet 5 are welded to both sides of the platform plate 4. The platform kick feet 5 are made of L50x50x5 angle steel with a vertical edge height of 50mm.

[0041] Railings 6 are installed on both sides of the platform. The uprights of railings 6 are made of steel pipes with a diameter of 32mm and are vertically welded to the connecting side plate 2, with a height of 1100mm. Two horizontal bars, also made of steel pipes with a diameter of 32mm, are installed between the uprights.

[0042] 2. Installation and Use: During the overall assembly stage: After the two transverse bulkhead sections on the same side have been initially positioned at the assembly site, this composite tooling tie beam device is hoisted to the hatch coaming at the top of the transverse bulkhead. The position of the device is adjusted so that its two ends are aligned with the two transverse bulkheads, and then the connecting side plates are firmly welded to the hatch coaming structure. At this point, the device serves to rigidly fix the distance between the two transverse bulkheads, and its upper platform also becomes a safe passage for construction personnel to move between the two bulkheads.

[0043] During the dock assembly phase: As the main sections are hoisted into the dock and joined together, the device continues to function, maintaining the precision of the cargo hold spacing.

[0044] Reuse Phase: After the main structural work and outfitting work in the transverse bulkhead area of ​​the cargo hold are completed, the welds connecting the side plates to the hatch coaming are cut using gas cutting, allowing the entire device to be lifted away. It can then be transported to an area with multiple container platform levels at the bow or stern of the cargo hold and horizontally erected between platform steps of different heights. At this point, it also serves to fix the step spacing and provide convenient personnel access.

[0045] Through the above methods, the composite tooling beam-pulling device has achieved multiple and multifunctional applications in different construction stages and different parts of the ship, demonstrating good economy and practicality.

[0046] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
