Description

Technical Field

[0001] This utility model relates to the field of steel pipe support technology, and in particular to a corrosion-resistant and lightweight steel pipe support structure for marine engineering. Background Technology

[0002] Offshore engineering is a broad field that encompasses engineering activities aimed at developing, utilizing, protecting, and restoring marine resources. During the construction of offshore engineering projects, corrosion-resistant and lightweight steel pipes are required. Corrosion-resistant coatings, such as polytetrafluoroethylene (PTFE) and epoxy resin, are applied to the surface of the steel pipes to enhance their resistance to corrosion. Furthermore, to reduce weight and lower transportation and installation costs, the design of corrosion-resistant steel pipes for offshore engineering takes into account material lightweighting, typically achieved by selecting high-strength, low-density materials.

[0003] Most existing steel pipes are used directly. When subjected to external forces, steel pipes are prone to bending, twisting or deformation, which may lead to a decrease in the stability of the overall structure. This instability may further cause damage or failure of other structural components. If steel pipes work under unstable or high stress conditions for a long time, they are prone to fatigue damage, accelerated corrosion and other problems, thereby shortening their service life.

[0004] Therefore, since most of the existing steel pipes are used directly, they are prone to bending, twisting or deformation when subjected to external forces, which may lead to a decrease in the stability of the overall structure. If this continues for a long time, it will also shorten their service life. A corrosion-resistant and lightweight steel pipe support structure for marine engineering can be designed, and the support structure can be installed on the steel pipe to improve the stability of the support structure. Utility Model Content

[0005] To overcome the problem that most existing steel pipes are used directly, and that steel pipes are prone to bending, twisting or deformation when subjected to external forces, which may lead to a decrease in the stability of the overall structure and shorten its service life if this continues for a long time.

[0006] The technical solution of this utility model is as follows: a corrosion-resistant lightweight steel pipe support structure for marine engineering, comprising a steel pipe body, an internal support module, and an external support module; multiple sets of internal support modules are laterally sleeved inside the steel pipe body for supporting from within the steel pipe body, and multiple sets of external support modules are laterally sleeved outside the steel pipe body for supporting from outside the steel pipe body. The internal support module includes an inner support ring plate, a reinforcing rib plate, an outer support ring plate, a plug-in post, and a plug-in hole. An outer support ring plate is sleeved outside the inner support ring plate, and multiple sets of reinforcing rib plates are installed around the outer support ring plate and the inner support ring plate. The external support module includes a support ring plate, a second connecting hole, a fixing post, a nut, a U-shaped support frame, and a mounting hole. The support ring plate is sleeved outside the steel pipe body, and a U-shaped support frame is installed below the outside of the support ring plate.

[0007] Preferably, based on the length of the steel pipe body, the internal support modules are arranged horizontally, assembled and welded, and then placed inside the steel pipe body. Next, the external support modules are fitted onto the outside of the steel pipe body for installation, providing external support for the steel pipe body. By installing support structures on the steel pipe body, the stability and safety of the structure can be maintained under various loads. This is particularly important for marine engineering because the marine environment is complex and changeable, and the structure needs to withstand the effects of various external forces such as wind, waves, and tides. At the same time, it can reduce maintenance and replacement costs caused by corrosion and extend the service life of the steel pipe body.

[0008] Preferably, the outer side of the steel pipe body has multiple sets of first connection holes for fixing and connecting the external support module.

[0009] Preferably, multiple sets of plug-in posts are installed around one side of the outer ring plate.

[0010] Preferably, the outer ring plate of the support has a plug hole on the side away from the plug post, corresponding to the plug post.

[0011] Preferably, the support ring plate has multiple sets of second connecting holes, and a fixing post passes through the center of each second connecting hole.

[0012] Preferably, a nut is fitted on the outside of the fixing column, and the fixing column passes through the second connecting hole and the first connecting hole to be positioned and connected to the steel pipe body.

[0013] Preferably, two sets of mounting holes are provided horizontally below the U-shaped support frame.

[0014] The beneficial effects of this utility model are:

Next, the external support modules are fitted onto the outside of the steel pipe body for installation, providing external support for the steel pipe body. By installing support structures on the steel pipe body, the stability and safety of the structure can be maintained under various loads.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a corrosion-resistant lightweight steel pipe support structure for marine engineering, comprising a steel pipe body 1, an internal support module, and an external support module; multiple sets of internal support modules are laterally sleeved on the inner side of the steel pipe body 1 for supporting from the inside of the steel pipe body 1, and multiple sets of external support modules are laterally sleeved on the outer side of the steel pipe body 1 for supporting from the outside of the steel pipe body 1. The internal support module includes an inner support ring plate 201, a reinforcing rib plate 202, an outer support ring plate 203, and a plug-in column. 204 and insertion hole 205, support inner ring plate 201 is fitted with support outer ring plate 203, support outer ring plate 203 and support inner ring plate 201 are surrounded by multiple sets of reinforcing ribs 202, the external support module includes support ring plate 301, second connection hole 302, fixing column 303, nut 304, U-shaped support frame 305 and mounting hole 306, support ring plate 301 is fitted on the outside of steel pipe body 1, and U-shaped support frame 305 is installed below the outside of support ring plate 301.

[0023] Please see Figures 2-3 In this embodiment, multiple sets of first connection holes 101 for fixing and connecting external support modules are opened horizontally around the outside of the steel pipe body 1. The first connection holes 101 facilitate the fixing and connection with the external support modules, improving the stability of the steel pipe body 1. Multiple sets of plug-in posts 204 are installed around one side of the support outer ring plate 203. According to the length of the steel pipe body 1, the support outer ring plate 203 is arranged horizontally in sequence to adjust to a suitable length. The side of the support outer ring plate 203 away from the plug-in post 204 is provided with plug-in holes 205 corresponding to the plug-in post 204. The plug-in post 204 drives one set of support outer ring plates 203 to be positioned and connected through the plug-in holes 205 on another set of support outer ring plates 203. Then, the connection point of the two sets of support outer ring plates 203 is welded together.

[0024] Please see Figure 4 In this embodiment, multiple sets of second connecting holes 302 are provided around the support ring plate 301. A fixing post 303 passes through the middle of the second connecting holes 302 of the support ring plate 301. After the outer support ring plate 203 is inserted into the steel pipe body 1, the support ring plate 301 is sequentially sleeved on the outside of the steel pipe body 1. A nut 304 is sleeved on the outside of the fixing post 303. The fixing post 303 passes through the second connecting hole 302 and the first connecting hole 101 and is positioned and connected to the steel pipe body 1. The fixing post 303 is picked up and passed through the second connecting hole 302 and the first connecting hole 101 and positioned and connected to the steel pipe body 1. Then, the nut 304 is tightened and fixed, so that the support ring plate 301 is fixed in the position outside the steel pipe body 1. Two sets of mounting holes 306 are provided horizontally below the U-shaped support frame 305. According to the position where the steel pipe body 1 needs to be placed, the bolts are passed through the mounting holes 306, so that the U-shaped support frame 305 is fixedly connected to the position where it needs to be placed.

[0025] During operation, the outer ring plates 203 are arranged horizontally in sequence according to the length of the steel pipe body 1 and adjusted to a suitable length. Then, the insertion column 204 drives one set of outer ring plates 203 to be positioned and connected through the insertion hole 205 on another set of outer ring plates 203. Then, the connection point of the two sets of outer ring plates 203 is welded together. Then, the welded outer ring plates 203 are gradually sent into the inner side of the steel pipe body 1.

[0026] After the outer ring plate 203 is inserted into the steel pipe body 1, the support ring plate 301 is sequentially fitted onto the outside of the steel pipe body 1. Then, the fixing column 303 is picked up and passed through the second connecting hole 302 and the first connecting hole 101 to be positioned and connected to the steel pipe body 1. Then, the nut 304 is tightened to fix the support ring plate 301 in the position outside the steel pipe body 1. Then, according to the position where the steel pipe body 1 needs to be placed, the bolt is passed through the mounting hole 306 to fix the U-shaped support frame 305 to the position where it needs to be placed.

[0027] During the use of the steel pipe body 1, the outer supporting ring plate 203 fits against the inner wall of the steel pipe body 1, and the inner supporting ring plate 201 and the reinforcing rib plate 202 provide stable support from inside the steel pipe body 1. At the same time, the supporting ring plate 301 cooperates with the U-shaped support frame 305 to stabilize the position of the steel pipe body 1 from the outside.

[0028] Through the above steps, based on the length of the steel pipe body 1, the internal support modules are arranged horizontally, assembled, and welded, and then placed inside the steel pipe body 1. Next, the external support modules are fitted onto the outside of the steel pipe body 1 for installation, providing external support for the steel pipe body 1. By installing a support structure on the steel pipe body 1, the stability and safety of the structure can be maintained under various loads. This is particularly important for marine engineering because the marine environment is complex and changeable, and the structure needs to withstand the effects of various external forces such as wind, waves, and tides. At the same time, it can reduce the maintenance and replacement costs caused by corrosion and extend the service life of the steel pipe body 1. This addresses the problem that most existing steel pipes are used directly, and when subjected to external forces, they are prone to bending, twisting, or deformation, which may lead to a decrease in the stability of the overall structure. If this continues for a long time, it will also shorten its service life.
