Description

Technical Field

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

[0002] In the construction of large container ships, the sectional assembly (midship assembly) and dock assembly (final assembly) of the cargo hold area are key technological processes; this area is typically composed of sections such as the bottom, sides, and multiple transversely arranged bulkheads. Traditional construction methods present the following problems: (1) Difficulty in controlling spacing: During the assembly and loading stages, the cargo hold spacing between two adjacent transverse bulkheads needs to be precisely maintained. Traditional methods lack effective special tooling and rely more on temporary supports and measurement adjustments, making precision control difficult, inefficient, and prone to deviation due to external forces or welding deformation during construction.

[0003] (2) Construction is inconvenient and there are safety hazards: The space between the transverse bulkheads is large and high, making it difficult for personnel to pass through. Construction equipment and tools (such as welding machines, toolboxes, and ventilation facilities) need to be frequently hoisted or placed in unsafe locations, which increases the risk of high-altitude operations and material handling time, affecting the overall construction efficiency.

[0004] (3) Single function: Existing temporary platforms or support structures are usually single in function, or only used for support, or only as simple walkways. They cannot simultaneously meet the multiple requirements of fixed spacing, safety passage and equipment bearing, resulting in the need to set up a variety of tools on site, occupying space and making management complicated.

[0005] Therefore, there is an urgent need for a specialized tooling device that integrates multiple functions, is safe and reliable, and is reusable, in order to solve the above problems and improve the accuracy, safety and efficiency of shipbuilding. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a composite tooling platform for container ship assembly and loading processes that is structurally stable, functionally integrated, and reusable. This platform can simultaneously achieve three major functions: accurately fixing cargo hold spacing, providing safe personnel passage, and temporarily placing construction equipment and tools.

[0007] The purpose of this utility model is achieved as follows: A composite tooling platform device for the assembly and loading process of container ships includes a platform plate, a support assembly and a guardrail assembly. The platform plate is fixedly installed on the top of the support assembly, and the guardrail assembly is disposed on the edge of the platform plate. The support assembly includes multiple vertically arranged columns, diagonal braces, elbow plates, main beams and secondary beams. The bottom end of the column is used for fixed connection with the hull structure, and a row of columns is provided on the front and rear sides below the bottom surface of the platform plate. The main beams and secondary beams form a supporting frame, which is set on the bottom surface of the platform plate; A diagonal brace is welded between the bottom of each column and the bottom surface of the platform plate, and an elbow plate is welded between the top of each column and the bottom surface of the platform plate. The guardrail assembly is installed on the left and right edges of the platform panel.

[0008] A composite tooling platform device for the assembly and loading process of container ships, wherein a row of columns is symmetrically arranged on the front and rear sides below the bottom surface of the platform plate, with 3 columns in each row.

[0009] A composite tooling platform device for the assembly and loading process of container ships, wherein one side of the platform plate is mounted on a reference transverse bulkhead section via columns, and the other side is mounted on a non-reference transverse bulkhead section via columns.

[0010] A composite tooling platform device for the assembly and loading process of container ships, wherein the main beam adopts an I-beam structure, and the I-beam is composed of HP280 bulb flat steel with 12mm thick panels welded on the top and bottom to provide the main load-bearing capacity.

[0011] A composite tooling platform device for the assembly and loading process of container ships, wherein the secondary beam adopts a combination structure of channel steel and angle steel.

[0012] A composite tooling platform device for the assembly and loading process of container ships, wherein the platform plate is made of 4mm thick patterned steel plate, which has both load-bearing and anti-slip functions.

[0013] A composite tooling platform device for the assembly and loading process of container ships, wherein the column is made of steel pipe with a diameter of 219mm and the height of the column is 0.8~1.5 meters, to avoid interference between the platform and the hatch cover accessories on the hatch coaming.

[0014] A composite tooling platform device for the assembly and loading process of container ships, wherein the diagonal brace is made of steel pipe with a diameter of 168mm and the elbow plate is made of plate with a thickness of 12mm and a diameter of 350mm x 350mm.

[0015] A composite tooling platform device for the assembly and loading process of container ships, wherein the guardrail assembly is welded from steel pipes with a diameter of 42mm.

[0016] Compared with the prior art, the beneficial effects of this utility model are: (1) High integration of functions: This utility model integrates three major functions, namely "fixed spacing", "safe passage" and "equipment carrying", through a stable platform structure. During the assembly and final assembly stages, by welding and fixing the bottom of the two end columns of the platform to the top of the two transverse bulkheads, it can effectively resist welding deformation and construction disturbance, and accurately maintain the cargo hold spacing. The wide platform provides a safe and convenient passage for construction personnel. At the same time, the platform can stably support various construction tools such as welding equipment, toolboxes, and painting machinery, avoiding clutter and the risk of falling objects from height.

[0017] (2) Stable and reliable structure: The platform uses columns as the main support and sets up a main and secondary beam frame composed of I-beams, channel steel and other materials under the platform plate to ensure the load-bearing capacity of the platform; the added diagonal bracing and elbow plate form a double-strength structure, which greatly enhances the overall rigidity and stability of the platform, and can withstand various loads during the construction process, ensuring construction safety.

[0018] (3) Standardization and reusability: The platform device of this utility model is designed and can be manufactured using standard profiles, which is easy to mass-produce and control quality. After completing the installation of the transverse bulkhead in a specific cargo hold area, it can be easily dismantled and transferred to other areas of the ship's bow and stern cargo holds (such as the multi-level steps of the container platform) for reuse. It is used to fix the step spacing and provide a construction platform. It has strong versatility and effectively reduces tooling costs and site occupation.

[0019] (4) Improve construction efficiency and accuracy: The application of the platform of this utility model reduces the time and manpower costs of temporary support and repeated measurement and adjustment in traditional processes; its integrated functions make the construction area planning neater, the material retrieval more convenient, and the personnel flow safer, thereby significantly improving the construction efficiency and accuracy control level of the overall assembly and final assembly stages.

Example

[0027] See Figure 1-5 , Figure 1 A structural schematic diagram of the composite tooling platform device of this utility model is shown. As shown in the figure, the composite tooling platform device of this utility model for the assembly and loading process of container ships is an independent, movable and reusable steel structure device, including a platform plate 1, a support assembly and a guardrail assembly 3. The platform plate 1 is fixedly installed on the top of the support assembly, and the guardrail assembly 3 is set on the edge of the platform plate 1. The support assembly includes multiple vertically arranged columns 2, diagonal braces 4, elbow plates 5, main beams 6 and secondary beams 7.

[0028] The bottom end of the column 2 is used to fix it to the hull structure. In this embodiment, a row of columns 2 is provided on the front and rear sides below the bottom surface of the platform plate 1, with 3 columns 2 in each row, arranged symmetrically. One side of the platform plate 1 is set on the reference transverse bulkhead section 8 through the column 2, and the other side is set on the non-reference transverse bulkhead section 9 through the column 2. That is, the bottom ends of the columns 2 on the left and right sides below the platform plate 1 are fixed to the top surface of the reference transverse bulkhead section 8 and the non-reference transverse bulkhead section 9, respectively.

[0029] The main beam 6 and the secondary beam 7 form a supporting frame and are set on the bottom surface of the platform plate 1. In this embodiment, the main beam 6 adopts an I-beam structure, and the secondary beam 7 adopts a grid structure composed of channel steel 7.1 and angle steel 7.2.

[0030] A diagonal brace 4 is welded between the bottom of each column 2 and the bottom surface of the platform plate 1 to ensure stability; at the same time, an elbow plate 5 is welded between the top of each column 2 and the bottom surface of the platform plate 1.

[0031] The guardrail assembly 3 is installed on the left and right edges of the platform plate 1 to provide safety protection.

[0032] In this embodiment, the platform plate 1 is made of 4mm thick patterned steel plate, which has both load-bearing and anti-slip functions.

[0033] In this embodiment, the column 2 is made of steel pipe with a diameter of 219mm and a height of about 1 meter; this height design is intended to avoid interference between the platform and hatch cover accessories (such as positioning pins) on the hatch coaming.

[0034] In this embodiment, the I-beam 6, which serves as the main beam, can be composed of HP280 bulb flat steel with 12mm thick panels welded on the top and bottom to provide the main load-bearing capacity.

[0035] In this embodiment, the diagonal brace 4 is made of a steel pipe with a diameter of 168mm, and the elbow plate 5 can be made of a 12mm thick, 350mm x 350mm plate. The diagonal brace 4 and the elbow plate 5 work together to form double reinforcement, effectively preventing the platform from shaking or overturning when under load.

[0036] In this embodiment, the guardrail assembly 3 is a railing made of steel pipe with a diameter of 42mm.

[0037] During the dock assembly and installation process, this platform serves multiple purposes: maintaining the cargo hold spacing between transverse bulkheads, facilitating personnel passage between the bulkheads, and providing temporary storage for various equipment and tools used in cargo hold construction. Toolboxes, welding equipment, ventilation systems, and painting machinery are placed on this platform. After construction in the transverse bulkhead area is completed, the platform can be moved to an area with numerous container platforms inside the fore and stern cargo holds, placed horizontally at the multi-level steps to facilitate maintaining the spacing between the transverse steps, personnel passage between the steps, and temporary storage for various equipment and tools used in cargo hold construction.

[0038] Working principle: During the final assembly (mid-joining) stage of the cargo hold area of ​​a container ship, when two transverse bulkheads on the same side are segmented (such as...) Figure 1 After the initial positioning of the reference transverse bulkhead segment 8 and the non-reference transverse bulkhead segment 9, the composite tooling platform device is hoisted between them. The bottom ends of the two rows of columns 2 at the front and rear of the platform are welded and fixed to the top deck structure of the transverse bulkhead segments 8 and 9, respectively. At this point, the platform achieves: (1) Fixed cargo hold spacing: Through its rigid structure, the two transverse bulkheads are firmly connected in sections to prevent the spacing from changing during subsequent construction.

[0039] (2) Provide personnel access: Construction personnel can safely pass between the two transverse bulkheads on platform 1.

[0040] (3) Supporting construction equipment: Welding machines, toolboxes, ventilation pipes and other equipment can be placed on the platform.

[0041] During the dock assembly phase, the platform continues to serve the aforementioned functions. Once the main work, such as welding, in this area is completed, the platform can be dismantled by gas cutting and transported to the multi-level steps of the container platform in the bow and stern cargo holds of the ship. It will be placed horizontally to fix the step spacing and serve as a platform for subsequent construction, thus achieving reuse.

[0042] This utility model has a reasonable structure and high functional integration, effectively solving specific technological problems in shipbuilding, and has good practicality and economy.
