Description

Technical Field

[0001] This utility model belongs to the field of pipe shoe installation and construction, and particularly relates to a guide and limiting block for corrosion protection. Background Technology

[0002] During the construction and installation of pipelines on offshore oil platforms, there are often difficulties in applying anti-corrosion coatings to the pipeline guide blocks, as well as blind spots where there is insufficient construction space to apply the coatings, leaving coating quality issues that pose significant quality and safety risks to the subsequent operation and commissioning of the pipelines.

[0003] In existing technologies, guide limit blocks are usually designed as guides cut from finished T-shaped steel. The guiding force is mainly applied to the two sides of the shoe sole plate. There is only a 3 mm anti-corrosion coating gap between the surface of the guide block and the surface of the shoe sole plate. The gap between the guide block and the shoe is basically unreachable, which leads to certain risks to the coating quality of the project.

[0004] Therefore, there is an urgent need to design a corrosion-resistant guide limit block to solve the problems mentioned above. Utility Model Content

[0005] To address the technical problem mentioned in the background art where the gap between the guide block and the tube shoe is too small to allow for welding and coating, a corrosion-resistant guide limiting block is provided.

[0006] To achieve the above objectives, the specific technical solution of the corrosion-resistant guide and limiting block of this utility model is as follows:

[0007] A corrosion-resistant guide and limiting block is disclosed. The cross-section of the corrosion-resistant guide and limiting block is elephant trunk shaped and is disposed on both sides of a pipe shoe. The pipe shoe includes a base disposed on a platform. The corrosion-resistant guide and limiting block includes a first plate and a second plate disposed perpendicular to each other, with the second plate connected to the middle position of the first plate. An avoidance groove is provided on the second plate, which is located below the connection between the first plate and the second plate. The distance between the second plate and the base is greater than that between the first plate. A gap is provided between the base and the first plate, and the avoidance groove can communicate with the gap.

[0008] Furthermore, the second plate includes a first welding surface, a second welding surface, and a concave surface. The first welding surface is located at the bottom of the second plate and is used for welding to the platform. The second welding surface is located on the side of the second plate and is used for welding to the first plate. The concave surface is connected to the first welding surface and the second welding surface respectively, and the concave surface can form a clearance groove.

[0009] Furthermore, the concave surface includes a first extension segment, a second extension segment, and a connecting segment. The first extension segment extends upward along the inner side of the first welding surface, and the second extension segment extends rearward along the inner side of the second welding surface. The second extension segment and the first extension segment are connected by the connecting segment.

[0010] Furthermore, the connection between the connecting segment and the first connecting segment and / or the second connecting segment is arc-shaped.

[0011] Furthermore, the first extension section and the second extension section are arranged perpendicular to each other so that the shape of the clearance groove is rectangular, and the length of one side of the rectangular clearance groove is 30mm-40mm, and the length of the other side is 20-30mm.

[0012] Furthermore, the second plate also includes a contour surface, which is sequentially connected end-to-end with the first welding surface, the concave surface, and the second welding surface to form the edge of the second plate. The contour surface is located on the upper side of the second plate.

[0013] Furthermore, the contour surface includes a top surface segment and a side surface segment, which intersect perpendicularly; the top surface segment is positioned relative to the first welding surface and above the concave surface, and the side surface segment is positioned relative to the second welding surface, with the side surface segment and the second welding surface located on opposite sides of the concave surface, respectively.

[0014] Furthermore, the length of the first welding surface is 3 / 4 to 4 / 5 of the length of the top surface segment, and the length of the second welding surface is 2 / 3 to 3 / 4 of the length of the side surface segment.

[0015] Furthermore, the connection points between the contour surface and the first welding surface, the connection points between the first welding surface and the concave surface, the connection points between the concave surface and the second welding surface, and the connection points between the second welding surface and the contour surface are all right-angle structures.

[0016] Furthermore, the distance between the bottom of the first plate and the platform, as well as the gap distance, are both set to 2mm-5mm.

[0017] The anti-corrosion guide and limiting block of this utility model has the following advantages: The original guide form cut from T-shaped steel is improved to a welded form of irregular steel plate. The design of the clearance groove allows sufficient space between the second plate and the base, which is convenient for painting operations and avoids dead corners. It not only meets the original functional clearance requirements, but also meets the space requirements for first-line anti-corrosion construction, effectively ensuring the quality of anti-corrosion construction of the guide block. In addition, the elephant trunk-shaped cross section and the arrangement on both sides enhance the guiding stability, allow the gap to be directly exposed, facilitate welding operations, improve welding quality and improve the installation accuracy of pipe shoes.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0024] The following is a reference to the appendix. Figure 1 To be continued Figure 2 This utility model describes a corrosion-resistant guide and limiting block.

[0025] This embodiment provides a corrosion-resistant guide and limiting block. Figure 1 This is a schematic diagram of the structure after the anti-corrosion guide and limiting block and the tube shoe are installed in this embodiment; as shown. Figure 1 As shown, the cross-section of the anti-corrosion guide limit block is elephant trunk shaped and is set on both sides of the pipe shoe 100. The pipe shoe 100 includes a base 200 set on the platform 400. The anti-corrosion guide limit block includes a first plate 1 and a second plate 2 arranged perpendicularly to each other, and the second plate 2 is connected to the middle position of the first plate 1. An avoidance groove 3 is provided on the second plate 2. The avoidance groove 3 is located below the connection between the first plate 1 and the second plate 2. The distance between the second plate 2 and the base 200 is greater than that between the first plate 1. A gap 300 is provided between the base 200 and the first plate 1, and the avoidance groove 3 can communicate with the gap 300.

[0026] The original T-shaped steel guide block for corrosion protection has been improved to a welded form of irregular steel plate. The design of the clearance groove 3 allows sufficient space between the second plate 2 and the base 200, which facilitates painting operations and avoids dead corners. It not only meets the original functional clearance requirements, but also meets the space requirements for front-line corrosion protection construction, effectively ensuring the quality of corrosion protection construction of the guide block. In addition, the elephant trunk-shaped cross section and the arrangement on both sides enhance the stability of the guide, allowing the gap 300 to be directly exposed, which facilitates welding operations, improves welding quality, and improves the installation accuracy of the pipe shoe 100.

[0027] It is understood that in this embodiment, the gap 300 is L-shaped and is formed on the first plate 1, platform 100 and base 200.

[0028] Figure 2 This is a schematic diagram of the anti-corrosion guide and limiting block in this embodiment.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the second plate 2 includes a first welding surface 21, a second welding surface 22, and a concave surface 23. The first welding surface 21 is located at the bottom of the second plate 2 and is used for welding with the platform 400. The second welding surface 22 is located on the side of the second plate 2 and is used for welding with the first plate 1. The concave surface 23 is connected to the first welding surface 21 and the second welding surface 22 respectively, and the concave surface 23 can form a relief groove 3.

[0030] Understandably, the aforementioned structure improves welding strength and enhances overall structural stability. Combined with the design of the concave surface 23 and the clearance groove 3, it provides a foundation for the subsequent formation of the clearance groove 3, facilitating welding and painting. Furthermore, multiple welding surfaces further distribute the stress on the second plate 2, preventing damage due to localized stress concentration.

[0031] Furthermore, such as Figure 2 As shown, the concave surface 23 includes a first extension 231, a second extension 232 and a connecting section 233. The first extension 231 extends upward along the inner side of the first welding surface 21, and the second extension 232 extends rearward along the inner side of the second welding surface 22. The second extension 232 and the first extension 231 are connected by the connecting section 233.

[0032] Understandably, the three-section design of the above structure gives the clearance groove 3 a clear boundary, which facilitates construction; the extended design of each section facilitates processing and manufacturing, improves production efficiency, makes the clearance groove 3 easier to align with the gap 300, and improves welding accessibility.

[0033] Specifically, such as Figure 2As shown, the connection between the connecting segment 233 and the first extension segment 231 and / or the second extension segment 232 is arc-shaped. The arc structure effectively disperses stress and prevents cracking. The arc transition design reduces coating dead angles, improves corrosion resistance, and facilitates subsequent coating. Furthermore, the arc structure is easy to process, reducing manufacturing difficulty. In addition, the connecting segment 233 can also be chamfered or multi-segmented; no specific limitation is made here. In this embodiment, the connection between the connecting segment 233 and the first extension segment 231 is designed as arc-shaped.

[0034] Furthermore, the first extension segment 231 and the second extension segment 232 are arranged perpendicularly to each other so that the shape of the clearance groove 3 is rectangular, and the length of one side of the rectangular clearance groove 3 is 30mm-40mm, and the length of the other side is 20-30mm.

[0035] Understandably, the standardized dimensions of the rectangular clearance groove 3 facilitate the operation of welding and painting tools, and the moderate size design with a side length of 20mm-40mm ensures welding space without occupying too much structural space. In addition, the regular rectangular shape makes it easy for construction personnel to quickly position and operate.

[0036] In this embodiment, the long side of the rectangular clearance groove 3 is set to 30mm and the short side is set to 25mm. In other embodiments, the specifications of the rectangular clearance groove can also be other values, which are not specifically limited here.

[0037] Furthermore, the second plate 2 also includes a contour surface 234, which is connected end to end with the first welding surface 21, the concave surface 23, and the second welding surface 22 to form the edge of the second plate 2. The contour surface 234 is located on the upper side of the second plate 2.

[0038] It is understandable that the contour surface 234 is connected end to end with the first welding surface 21, the concave surface 23 and the second welding surface 22 to form a complete edge, which improves the overall rigidity of the plate and the edge structure can enhance the stability of the plate under stress.

[0039] Specifically, during processing, workers can use the contour surface 234 as an installation reference surface to improve installation accuracy.

[0040] Furthermore, such as Figure 2 As shown, the contour surface 234 includes a top surface segment 2341 and a side surface segment 2342, which intersect perpendicularly. The top surface segment 2341 is disposed relative to the first welding surface 21 and located above the concave surface 23, and the side surface segment 2342 is disposed relative to the second welding surface 22, with the side surface segment 2342 and the second welding surface 22 located on both sides of the concave surface 23, respectively.

[0041] Understandably, the division of the top section 2341 and the side section 2342 makes the outline structure clearer, which is convenient for processing and assembly. Different sections bear the force in different directions, which improves the structural stability. On the other hand, using the top section 2341 as a guide surface can improve the centering of the workers during installation.

[0042] Furthermore, the length of the first welding surface 21 is 3 / 4 to 4 / 5 of the length of the top surface segment 2341, and the length of the second welding surface 22 is 2 / 3 to 3 / 4 of the length of the side surface segment 2342.

[0043] Understandably, the above-mentioned proportional design ensures sufficient welding area while avoiding material waste, conforms to the laws of mechanical distribution, improves the load-bearing capacity of the overall structure, and the fixed proportion facilitates mass production and quality control.

[0044] Furthermore, the connection points between the contour surface 234 and the first welding surface 21, the connection points between the first welding surface 21 and the concave surface 23, the connection points between the concave surface 23 and the second welding surface 22, and the connection points between the second welding surface 22 and the contour surface 234 are all right-angle structures.

[0045] It is understandable that right-angled structures do not require high-precision CNC equipment or complex molds, making them suitable for mass production and offering the advantage of short processing time, thus helping to improve the efficiency of automated production. In some embodiments, the aforementioned right-angled structure can also be replaced with an arc structure or a polyline structure. Specifically, the arc structure can effectively alleviate stress concentration, reduce sharp corners, and avoid areas that are difficult to cover with paint, while the polyline structure is suitable for various processing techniques, such as laser cutting and bending. Compared to arc or polyline structures, right-angled structures have simpler processing techniques, such as bending and shearing, which can be achieved through conventional processes. Therefore, operators can choose the appropriate structure according to actual needs, and this embodiment does not impose specific limitations.

[0046] Furthermore, the distance between the bottom of the first plate 1 and the platform 400, as well as the distance of the gap 300, are both set to 2mm-5mm.

[0047] Understandably, the 2mm-5mm allowance and 300mm gap facilitate the entry of painting tools, ensure full coverage of the anti-corrosion coating, and ensure smooth operation for welding personnel or equipment. This ensures structural strength while avoiding construction difficulties caused by excessively small gaps, thus balancing structural stability and anti-corrosion performance.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
