Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and more specifically, it relates to a ship precision base protection device. Background Technology

[0002] With the rapid development of the global shipping industry, the shipbuilding industry is facing the challenges of shorter cycles and higher efficiency. To accelerate construction, the installation milestones of many outfitting components are being significantly advanced, including precision bases with extremely high requirements for surface roughness and flatness. These bases are typically used to install high-precision equipment, and their processing and installation quality directly affects the operational performance of the equipment. However, in the later stages of shipbuilding, welding, painting, and handling operations can easily damage the installed precision bases, causing surface scratches, corrosion, or structural deformation, leading to a decrease in equipment installation accuracy and even affecting the overall performance of the ship. Furthermore, after early installation, these precision bases often require subsequent welding operations, painting, equipment handling, and other processes. In the complex construction environment, the base surface is highly susceptible to damage from welding spatter, mechanical impacts, and oil corrosion. Especially for precision mating surfaces requiring a surface roughness of Ra≤3.2μm, even slight scratches or corrosion can prevent the equipment from achieving the specified fit accuracy during installation. Therefore, there is an urgent need to develop a dedicated protective device that can provide long-term, stable, and reliable protection for precision bases in the complex environment of shipbuilding. Current protective measures commonly used in shipyards (such as temporary application of rust-preventive oil or covering with plastic film) have significant shortcomings: rust-preventive oil is easily contaminated and rendered ineffective by subsequent construction work; plastic film is easily damaged and difficult to secure. These traditional methods cannot provide long-term, stable protection and may also lead to secondary contamination due to residual protective materials.

[0003] Existing technology, titled "Pump Base and Ship," with publication (announcement) number "CN117698950A," belongs to the field of ship outfitting technology. It discloses a pump base and a ship. The pump base is used to mount a marine pump on the deck. The panel of the pump base is parallel to the deck and is used to mount the marine pump. A vertical plate is fixedly connected to the panel and is used for mounting on the deck, thus allowing the marine pump to be mounted on the deck. Furthermore, multiple elbow plates are provided; some elbow plates are fixedly connected to one side of the vertical plate, and others are fixedly connected to the other side of the vertical plate. One end of the elbow plate is mounted on the deck, and the other end is connected to the panel, allowing the vertical plate to be stably mounted on the deck. Additionally, the elbow plates connected to the panel provide additional support to the panel, improving the stability of the support. The structural strength of this pump base meets the installation requirements of the marine pump, and the structure is simple. Its panel, vertical plate, and elbow plates are easy to weld and assemble. Moreover, the panel does not require drilling holes to complete the welding between the pump base and the deck.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a ship precision base protection device that is simple in structure, can provide stable and reliable shielding protection for precision bases in the complex environment of shipbuilding, ensures their surface accuracy and structural integrity, and takes into account the convenience of disassembly and assembly and adaptability, so as to meet the needs of different bases and construction conditions.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is a ship precision base protection device, including a device panel, a precision base set on the ship's steel structure, multiple connectors set on the outer ring of the device panel, bolts set at the bottom of the connectors, the bolts passing through angle steel, the angle steel connecting to a pad, and the pad connecting to the ship's steel structure.

[0007] A high-temperature resistant silicone pad is adhered to the lower surface of the device panel.

[0008] The device panel has a circular or polygonal structure.

[0009] The lower surface of the device panel is attached to the upper surface of the precision base, the area of ​​the device panel is larger than the area of ​​the upper surface of the precision base, and the connector is located on the outside of the precision base.

[0010] The outer ring of the device panel has multiple connectors spaced at equal intervals. The connectors are perpendicular to the device panel and can be round rods, plates, or triangular angle steel structures.

[0011] The angle steel is vertically welded to a backing plate, and the backing plate is used to weld the ship's hull steel structure.

[0012] Multiple lifting lugs are fixedly installed on the panel of the device.

[0013] The device panel has an outer ring reinforcing plate on its outer edge and a surface reinforcing plate on its lower surface.

[0014] The surface reinforcing plates are arranged in a cross pattern, and the ends of the surface reinforcing plates are welded to the corresponding outer ring reinforcing plates.

[0015] The working principle and beneficial effects of this utility model are as follows: The ship precision base protection device described in this utility model is designed to protect the precision base after it has been installed on the ship's hull steel structure. Specifically, the device panel is attached to the upper surface of the precision base. The connecting parts of the outer ring of the panel extend vertically downwards, close to the hull steel structure. Bolts at the bottom of the connecting parts pass through angle steel, which is then fixedly connected to a pad. The pad is then fixedly connected to the hull steel structure, thus achieving a secure connection between the protection device and the hull steel structure. This provides reliable protection for the precision base. In subsequent stages of ship construction, this effectively prevents damage to the installed precision base caused by welding, painting, and handling operations, such as surface scratches, corrosion, or structural deformation. This avoids a decrease in equipment installation accuracy and ensures that the overall performance of the ship is not affected by construction work. Attached Figure Description

[0017] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 - Appendix Figure 6As shown, this utility model is a protective device for a ship's precision base, including a device panel 1, a precision base 3 mounted on a ship's steel structure 2, multiple connectors 4 arranged around the outer ring of the device panel 1, bolts 5 at the lower part of the connectors 4, the bolts 5 passing through angle steel 6, the angle steel 6 connecting to a pad 7, and the pad 7 connecting to the ship's steel structure 2. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. When the structure is installed, after the precision base 3 is placed on the ship's steel structure 2, the protective device can be used to protect the base. Specifically, the device panel 1 of the protective device is attached to the upper surface of the precision base 3. At this time, the connectors 4 around the outer ring of the device panel 1 extend vertically downwards to a position close to the ship's steel structure 2. The bolts 5 at the lower part of the connectors 4 pass through the angle steel 6, the angle steel 6 is fixedly connected to the pad 7, and the pad 7 is fixedly connected to the ship's steel structure 2, thus achieving a fixed connection between the protective device and the ship's steel structure 2. Therefore, the protective device provides reliable shielding and protection for the precision base. In this way, during the later stages of shipbuilding, damage to the installed precision base caused by welding, painting, and handling operations can be effectively avoided, such as surface scratches, corrosion, or structural deformation. This prevents a decrease in equipment installation accuracy and ensures that the overall performance of the ship is not affected by construction. The ship precision base protection device described in this utility model has a simple structure and can provide stable and reliable shielding protection for the precision base in the complex environment of shipbuilding, ensuring its surface accuracy and structural integrity. At the same time, it takes into account the convenience of disassembly and assembly and adaptability to meet the needs of different bases and construction conditions.

[0018] A high-temperature resistant silicone pad 8 is adhered to the lower surface of the device panel 1. In this structure, the high-temperature resistant silicone pad 8 serves as a buffer layer. By attaching the high-temperature resistant silicone pad to the inside of the panel, it absorbs external impacts on the precision base, preventing hard contact and thus further protecting the precision base.

[0019] The device panel 1 has a circular or polygonal structure. The shape of the device panel 1 is determined according to the shape of the precision base 3, effectively shielding the precision base 3 from above.

[0020] The lower surface of the device panel 1 is attached to the upper surface of the precision base 3, and the area of ​​the device panel 1 is larger than the area of ​​the upper surface of the precision base 3. The connector 4 is located on the outside of the base 3. This structure effectively achieves complete shielding of the precision base, preventing damage to it.

[0021] The outer ring of the device panel 1 is equipped with multiple connectors 4 spaced equidistantly at intervals. Each connector 4 is perpendicular to the device panel 1 and can be a round rod, plate, or triangular angle steel structure. In this structure, the connectors are fixedly connected to the device panel, and the connectors are bolted to the angle steel and the pad, reliably achieving a fixed connection with the ship's steel structure 2. The bolts pass through the oblong holes at the bottom of the connectors, allowing for adjustment of the bolt position within a certain range to meet the protection requirements of precision bases at different heights.

[0022] The angle steel 6 is vertically welded to the backing plate 7, and the backing plate 7 is welded to the ship hull steel structure 2.

[0023] Multiple lifting lugs 11 are fixedly installed on the device panel 1. In this structure, the lifting lugs facilitate the lifting of the protective device, allowing it to be placed in position for protection and removed when not in use.

[0024] The device panel 1 has an outer ring reinforcing plate 9 around its outer edge, and the device panel 2 has a surface reinforcing plate 10 on its lower surface. The surface reinforcing plates 10 are arranged in a crisscross pattern, and their ends are welded to corresponding outer ring reinforcing plates 9. In this structure, the outer ring reinforcing plates 9 and the surface reinforcing plates 10 enhance the strength of the device panel 1. The surface reinforcing plates 10 are optional; they can be included or omitted.

[0025] The ship precision base protection device described in this utility model uses a steel plate (thickness ≥ 5mm) as the panel to cover the upper surface of the precision base. The steel plate surface is rust-proofed and can completely cover the precision mating surfaces of the precision base. The connecting parts are made of triangular angle steel and are connected to the angle steel with high-strength bolts (such as grade 8.8). A welded connecting plate is then used, and the plate is welded to the ship's steel structure to achieve a tight connection. A high-temperature resistant silicone pad absorbs external impacts and avoids hard contact.

[0026] The ship precision base protection device described in this utility model, when structurally installed, can protect the precision base 3 after it is placed on the ship's hull steel structure 2. Specifically, the device panel 1 of the protection device is attached to the upper surface of the precision base 3. At this time, the connecting piece 4 on the outer ring of the device panel 1 extends vertically downward to a position close to the hull steel structure 2. Then, the bolt 5 at the lower part of the connecting piece 4 passes through the angle steel 6, and the angle steel 6 is fixedly connected to the pad 7. The pad 7 is fixedly connected to the hull steel structure 2, thus achieving a fixed connection between the protection device and the hull steel structure 2. The protection device then provides reliable shielding and protection for the precision base. In this way, during the subsequent stages of ship construction, it effectively avoids damage to the installed precision base caused by welding, painting, handling, and other operations, such as surface scratches, corrosion, or structural deformation, thereby preventing a decrease in equipment installation accuracy and ensuring that the overall performance of the ship is not affected by construction.
