The present application relates to the technical field of pipeline bracket, and discloses a transverse flexible bracket structure, which comprises a orthotropic upper wing plate bent along a transverse direction, a thin-walled web plate, a double-cylinder-shaped support frame and a easily-tearable drain hole structure. The bracket has small transverse rigidity and high transverse deformation energy consumption capacity, so that the influence of transverse impact of the vertical pipeline on the bracket is reduced, and the probability of damage of the pipeline and the bracket is reduced.

Description

Technical Field

[0001] This invention relates to the field of pipe bracket technology, specifically a transverse flexible bracket structure. Background Technology

[0002] Traditional chemical pipeline supports are I-shaped structures, with the pipeline resting against the top surface of the support and supported by it. The I-shaped structure provides high vertical stiffness, allowing for stable pipeline support. However, such supports also exhibit high lateral stiffness. With vertically arranged chemical pipelines located on one side of the support, the instantaneous change in flow velocity of the chemical raw materials within the pipeline when valves open or close can cause a reaction force that likely leads to lateral movement of the pipeline—a phenomenon known in the industry as water hammer. This lateral movement causes the pipeline to impact the support. Due to the support's high lateral stiffness, it cannot effectively absorb the kinetic energy generated by this impact, resulting in a rigid collision between the support and the pipeline. This makes the pipeline susceptible to damage and the support prone to fracture and detachment at the root weld. In summary, existing technologies suffer from the technical problem of easy damage to both the support and the pipeline upon collision. Summary of the Invention

[0003] To address the existing technical problems, the purpose of this invention is to provide a lateral flexible bracket structure that can solve the technical problem described in the background art of easy damage to brackets and pipes.

[0004] The present invention provides a transversely flexible bracket structure, including an orthotropic upper flange extending laterally in a bent manner and two thin-walled webs arranged side by side in the transverse direction below the orthotropic upper flange; the top side of the thin-walled webs is welded to the bottom surface of the orthotropic upper flange, and the thin-walled webs extend downward from the bottom surface of the orthotropic upper flange; a cylindrical support frame for welding with external components is provided below the thin-walled webs; the bottom side of the thin-walled webs is welded to the top surface of the cylindrical support frame.

[0005] Optionally, the orthotropic upper wing extends in a transversely alternating up-and-down bending manner.

[0006] Optionally, the orthotropic upper flange includes two first sides symmetrically arranged in the transverse direction, the two first sides extending upward and the tops of the two first sides bending inward to form an abutment portion for supporting the pipe at the top of the first side.

[0007] Optionally, the orthotropic upper flange includes at least one upwardly curved first bend, the top surface of which is flush with the top surface of the abutment portion, for supporting the pipe.

[0008] Optionally, the orthotropic upper flange includes at least two downwardly curved second bends, with each first bend adjacent to a second bend on both sides in the transverse direction; the bottom wall of each second bend has a drainage hole for drainage.

[0009] Optionally, the number of first bends is at least two, with two thin-walled webs welded to the bottom surfaces of the two first bends respectively.

[0010] Optionally, the orthotropic upper flange includes two oppositely arranged second sides, with the two ends of the second sides respectively connected to the two first sides; one of the two second sides is a first welding side for welding with an external component, and the first welding side has at least one crack-stopping notch; the crack-stopping notch is located between the two ends of the first welding side.

[0011] Optionally, the thin-walled web includes a second weld side for welding to an external member, the second weld side being located below the first weld side.

[0012] Optionally, a cylindrical support frame for welding to external components is provided below the thin-walled web; the cylindrical support frame is formed by rolling a steel plate; the orthographic projection of the thin-walled web on the top surface of the cylindrical support frame is located between the two sides of the top surface of the cylindrical support frame in the transverse direction, and the bottom side of the thin-walled web is welded to the top surface of the cylindrical support frame.

[0013] Optionally, the two ends of the steel plates are stacked and welded together, with the ends of the steel plates spaced apart from the vertical sidewalls of the cylindrical support frame.

[0014] Optionally, the weld strength between the two ends of the steel plate is less than the weld strength between the thin-walled web and the top surface of the cylindrical support frame. Fillet welds are used between the two ends of the steel plate, while butt welds with full penetration are used between the thin-walled web and the top surface of the cylindrical support frame.

[0015] This application provides a transverse flexible bracket structure. When the transverse flexible bracket structure is subjected to a transverse impact from a pipe, the pipe will first impact the orthotropic upper flange in the transverse direction. The orthotropic upper flange extends in a transverse bending manner and intersects with the I-shaped bracket of the prior art. The orthotropic upper flange of this application is more likely to deform and absorb the impact kinetic energy. This makes the impact kinetic energy received by the transverse flexible bracket structure and the vertically arranged pipe smaller, thereby reducing the probability of damage to the pipe and the bracket.

[0016] Furthermore, since the orthotropic upper flange receives the impact from the pipe first, when the kinetic energy of the pipe impact is small, the degree of lateral deformation of the orthotropic upper flange is small, and the amplitude of the pipe's lateral movement is also small. Therefore, the probability of the pipe directly impacting the thin-walled web is small, which provides better protection for the thin-walled web. The thin-walled web still plays a good supporting and connecting role for the orthotropic upper flange, and the lateral flexible bracket structure of this application will not easily fall off. Furthermore, even if the thin-walled web near the impact side falls off due to impact, there is still another thin-walled web supporting and connecting the orthotropic upper flange, which makes the lateral flexible bracket structure of this application not easily fall off.

[0017] In summary, the transverse flexible bracket structure of this application adopts the aforementioned structural scheme, which can reduce the probability of damage and detachment of the transverse flexible bracket structure and the probability of pipe damage, thus solving the technical problems of the prior art.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0029] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0030] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this application are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0031] Please see Figure 1 , Figure 2 and Figure 6 This application provides an exemplary description of a transverse flexible bracket structure, comprising an orthotropic upper flange 10 extending laterally in a bent manner, and two thin-walled webs 20 arranged side-by-side below the orthotropic upper flange 10 in a transverse direction. The top side of the thin-walled webs 20 is welded to the bottom surface of the orthotropic upper flange 10, and the thin-walled webs 20 extend downward from the bottom surface of the orthotropic upper flange 10. The two thin-walled webs 20 and the orthotropic upper flange 10 are arranged in a roughly "π" shape. Both the two thin-walled webs 20 and the orthotropic upper flange 10 are welded to external components, such as the wall of a shaft. The top surface of the orthotropic upper flange 10 can support a transversely extending pipe 100a. In addition, a vertically extending pipe 100b is also arranged on one side of the orthotropic upper flange 10.

[0032] In one application scenario, the transverse flexible bracket structure of this embodiment is installed inside a vertical shaft. The orthotropic upper flange 10 and the two thin-walled webs 20 are welded to the shaft wall or its mounting components on the side facing the shaft wall, thus fixing the orthotropic upper flange 10 and the two thin-walled webs 20 to the shaft wall. The transversely extending pipe 100a abuts against the top surface of the orthotropic upper flange 10, and is supported by the orthotropic upper flange 10 and the two thin-walled webs 20. This ensures that the orthotropic upper flange 10 will not easily break or fall off when subjected to the gravity of the transversely extending pipe 100a, thereby giving the transverse flexible bracket structure of this embodiment good vertical stiffness and providing stable support for the transversely extending pipe 100a. Furthermore, in this application scenario, vertically extending pipes 100b are arranged on one side of the transverse flexible bracket structure. When subjected to water hammer, the vertically extending pipes 100b are highly likely to move laterally and impact the transverse flexible bracket structure. Of course, in other application scenarios, the transverse flexible bracket structure is not limited to installation in vertical shafts; it can also be installed in other applicable application scenarios.

[0033] In this embodiment, the two thin-walled webs extend downwards from the bottom surface of the orthotropic upper flange 10, specifically arranged in a "π" shape with the orthotropic upper flange 10. When the vertically extending pipe 100b moves laterally, the pipe will first impact the orthotropic upper flange 10. Since the orthotropic upper flange 10 extends laterally in a bent manner, intersecting with the I-shaped bracket of the prior art, the orthotropic upper flange 10 of this embodiment is more likely to deform and absorb impact kinetic energy. This results in a smaller impact kinetic energy on the laterally flexible bracket structure and the vertically extending pipe 100b, thereby reducing the probability of damage to the pipe and bracket. Furthermore, since the orthotropic upper flange 10 receives the impact from the pipe first, when the kinetic energy of the vertically extending pipe 100b impact is small, the degree of lateral deformation of the orthotropic upper flange 10 is small, and the amplitude of the vertically extending pipe 100b moving laterally is also small. Therefore, the probability of the vertically extending pipe 100b impacting the thin-walled web 20 is small, which provides better protection for the thin-walled web 20. The thin-walled web 20 still provides good support and connection for the orthotropic upper flange 10. The lateral flexible bracket structure of this embodiment will not easily fall off, thereby preventing the laterally extending pipe 100a from falling and being damaged due to lack of effective support.

[0034] Furthermore, even if the thin-walled web 20 near the impact side is detached due to impact, another thin-walled web 20 still supports and connects the orthotropic upper wing 10, thus preventing the transverse flexible bracket structure of this embodiment from easily detaching.

[0035] In summary, the transverse flexible bracket structure of this embodiment, employing the aforementioned structural solution, can reduce the probability of damage and detachment of the transverse flexible bracket structure and the probability of pipe damage, thus solving the technical problems of the prior art.

[0036] In another embodiment of this application, the orthotropic upper wing 10 extends in a transversely alternating bending pattern. This results in better deformation of the orthotropic upper wing 10 in the transverse direction, thereby better absorbing the kinetic energy of a transverse impact. For example, the orthotropic upper wing 10 extends in a wavy shape in the transverse direction (e.g., Figure 3 (as shown), or, the orthotropic upper flange 10 extends alternately in the transverse direction with upward approximately right-angle bends and upward approximately right-angle bends (as shown). Figure 1 As shown), or a broken line extension (such as...). Figure 4 As shown), or an arc-shaped extension (such as...). Figure 5 (as shown), or extend in other irregular curved shapes, etc.

[0037] In another embodiment of this application, the orthotropic upper flange 10 includes two first sides 11 arranged laterally opposite to each other. The two first sides 11 extend upward and their tops are bent inward to form an abutment portion 111 for supporting the pipe at the top of the first side 11. Preferably, the abutment portion 111 extends laterally, which makes the contact area between the abutment portion 111 and the pipe larger, thus providing better support for the pipe.

[0038] In another embodiment of this application, the orthotropic upper flange 10 includes at least one upwardly curved first bend 14, the top surface of which is flush with the top surface of the abutment portion 111, for supporting the pipe. Specifically, in this embodiment, two first bends 14 are configured, spaced apart, and the top surfaces of the two abutment portions 111 and the two first bends 14 together support the transversely arranged pipe, providing relatively stable support for the pipe. Furthermore, the top sides of the two thin-walled webs 20 are respectively welded to the bottom walls of the two first bends 14. Furthermore, the configuration of two first bends 14, with the two thin-walled webs 20 respectively welded to the bottom surfaces of the two first bends 14, makes the transverse flexible bracket structure more compact in the vertical direction, smaller in size, and helps save manufacturing materials.

[0039] In another embodiment of this application, the orthotropic upper wing 10 includes at least two downwardly curved second bends 13, with each first bend 14 adjacent to a second bend 13 on both sides in the lateral direction; each second bend 13 has a drainage hole 131 on its bottom wall for drainage. Specifically, in this embodiment, the number of second bends 13 is three. The drainage holes 131 can serve both a drainage function and a shock-absorbing function.

[0040] In another embodiment of this application, the orthotropic upper flange 10 includes two opposing second sides, with each end of the second side connected to one of the first sides. Specifically, the extension direction of the second side is perpendicular to the lateral direction and perpendicular to the extension direction of the first side. One of the two second sides is a first welding side 12 for welding to an external component. Specifically, the first welding side 12 is welded to the shaft wall. The first welding side 12 has at least one crack-stopping notch 121, located between the two ends of the first welding side 12. Since the crack-stopping notch 121 can interrupt the welding continuity between the first welding side 12 and the shaft wall, when one side of the orthotropic upper flange 10 is impacted by a vertically arranged pipe in the lateral direction, even if the side of the first welding side 12 closest to the vertically arranged pipe falls off, it will not easily fall off completely due to the blocking effect of the crack-stopping notch 121. In addition, the crack arresting notch 121 can also play a good buffering role, which is conducive to the orthotropic upper wing plate 10 absorbing impact kinetic energy better.

[0041] In another embodiment of this application, the thin-walled web 20 includes a second weld side for welding to an external member, the second weld side being located below the first weld side 12.

[0042] In another embodiment of this application, a cylindrical support frame 30 for welding to external components is provided below the thin-walled web 20. Specifically, the cylindrical support frame 30 is welded to the shaft wall. The cylindrical support frame 30 is formed by rolling a steel plate 31. The orthographic projection of the thin-walled web 20 onto the top surface of the cylindrical support frame 30 is located between the two sides of the top surface of the cylindrical support frame 30 in the lateral direction, and the bottom side of the thin-walled web 20 is welded to the top surface of the cylindrical support frame 30. When the orthotropic upper flange 10 is subjected to a lateral impact from the pipe and undergoes a large deformation, the cylindrical support frame 30 will be impacted by the pipe before the thin-walled web 20, thereby absorbing the lateral impact kinetic energy of the impacting pipe. This can significantly reduce the probability of the thin-walled web 20 being damaged and falling off due to impact. In addition, the cylindrical support frame 30 provides support for the thin-walled web 20, which is beneficial to improving the vertical stiffness of the lateral flexible bracket structure.

[0043] In another embodiment of this application, the two ends of the steel plate 31 are stacked and welded, and the ends of the steel plate 31 are spaced apart from the vertical sidewalls of the cylindrical support frame 30, thereby forming a buffer space between the ends of the steel plate 31 and the vertical sidewalls of the cylindrical support frame 30. When the cylindrical support frame 30 is subjected to a lateral impact from the pipe, the ends of the steel plate 31 have sufficient space to deform, thus improving the absorption of impact kinetic energy. Of course, in other embodiments, the end faces of the two ends of the steel plate 31 are fitted together and welded. After the cylindrical support frame 30 is subjected to a lateral impact, the welded joints at both ends of the steel plate 31 are more prone to breakage than other parts of the steel plate 31, thereby guiding the cylindrical support frame 30 to undergo elastic deformation, making it easier for the cylindrical support frame 30 to deform and better absorb impact kinetic energy.

[0044] In another embodiment of this application, the weld strength between the two ends of the steel plate 31 is less than the weld strength between the thin-walled web 20 and the top surface of the cylindrical support frame 30. Even after the cylindrical support frame 30 is deformed by a lateral impact from the pipe, the connection between the cylindrical support frame 30 and the thin-walled web 20 is still highly probable. Specifically, the two ends of the steel plate 31 are welded at multiple points, while the top surface of the cylindrical support frame 30 and the thin-walled web 20 are welded continuously. This ensures that the weld strength between the two ends of the steel plate 31 is less than the weld strength between the thin-walled web 20 and the top surface of the cylindrical support frame 30. Multi-point welding refers to multiple welded joints, each spaced apart; specifically, fillet welds are used. Continuous welding refers to a continuous, uninterrupted weld; specifically, butt welds are used.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the protection scope of this application.
