Description

Technical Field

[0001] The present invention relates to the technical field of pipeline supports and hangers, and in particular to a highly flexurally resistant pipeline support / hanger pipe assembly structure and method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Pipe supports and hangers include two types: brackets and hangers. Pipe supports and hangers are used to support and suspend the weight of pipelines and working media, so that the stress on the pipeline does not exceed the allowable stress of the material. At the same time, the supports and hangers play a role of activity and guidance when the pipeline expands and contracts, and limit the size and direction of the pipeline displacement, so that the pipeline can operate safely in a relatively fixed position.

[0004] The existing pipe supports / hangers are single-point pull or support for horizontal pipes. The pipes are affected by gravity, and have large flexible deformation and deflection. Considering the safety of the pipeline system, in order to control the deflection, the spacing between pipe supports / hangers will be limited. When faced with a span that exceeds the spacing between supports / hangers, additional civil engineering structural solutions such as integrated pipe racks and cantilever supports are often used to solve the problem. The solution is complex and the cost is high. Summary of the invention

[0005] In order to solve the above problems, the present invention proposes a highly flexural-resistant pipe support / hanger pipe assembly structure and method, which can increase the spacing between supports and hangers by improving the flexible deformation of the pipeline and reducing the deflection, thereby solving the problem of the required spanning distance exceeding the allowable spacing of general supports and hangers, and does not require the addition of additional civil engineering structures. The solution is simple and low-cost.

[0008] The first outer supporting member and the second outer supporting member can support the pipeline upward, and the middle pulling member can tighten the pipeline downward, thereby collecting the tension and pressure generated at different positions of the pipe part on the high flexural resistance supporting structure to offset the deflection deformation of the pipeline.

[0009] As a further solution, the anti-bending adjustment device comprises: a first threaded rod and a second threaded rod connected to the bottom connecting piece of the middle pull-back component; the first threaded rod and the second threaded rod are symmetrically arranged;

[0010] The first threaded pull rod and the second threaded pull rod respectively extend from the upper surface of the high-flexural resistance support structure body into the interior thereof. Each threaded pull rod is provided with an elastic support member and an adjustment nut is provided at the end. The elastic support member is arranged between the high-flexural resistance support structure body and the adjustment nut. The elastic force of the elastic support member can be adjusted by adjusting the nut, thereby adjusting the downward pulling force of the pull rod on the middle pull-back member.

[0011] In other embodiments, the following technical solutions are adopted:

[0012] A working method of the above-mentioned high-flexure-resistant pipe support pipe assembly structure includes:

[0013] The pipeline passes through the first outer support component, the middle pull-back component and the second outer support component in sequence; wherein, the first outer support component and the second outer support component provide upward support to the pipeline; the middle pull-back component exerts downward pulling force on the pipeline; thereby, the tension and pressure generated at different positions of the pipe are gathered on the high-flexural resistance support structure to offset the deflection deformation of the pipeline.

[0014] In other embodiments, the following technical solutions are adopted:

[0015] A high-flexure-resistance pipe hanger pipe assembly structure comprises: a high-flexure-resistance suspension structure body, a first outer suspension component, a middle lower support component and a second outer suspension component are sequentially arranged on the lower surface of the high-flexure-resistance support structure body along the axial direction of the pipe; the first outer suspension component and the second outer suspension component are respectively fixed on the lower surface of the high-flexure-resistance support structure body, and the middle lower support component is connected to the inside of the high-flexure-resistance support structure body through an anti-flexure adjustment device;

[0016] The first outer lifting member and the second outer lifting member can lift the pipeline upward, and the middle lower supporting member can support the pipeline downward, so that the tension and pressure generated at different positions of the pipe are collected on the high flexural resistance supporting structure to offset the deflection deformation of the pipeline.

[0017] As a further solution, the anti-bending adjustment device includes: a first threaded support rod and a second threaded support rod connected to the top connecting piece of the middle lower support component; the first threaded support rod and the second threaded support rod are symmetrically arranged;

[0020] A working method of the above-mentioned high-flexure-resistant pipe hanger pipe assembly structure includes:

[0021] The pipeline passes through the first outer lifting component, the middle lower supporting component and the second outer lifting component in sequence; wherein, the first outer lifting component and the second outer lifting component play the role of lifting the pipeline upward; the middle lower supporting component plays the role of supporting the pipeline downward; thereby, the tension and pressure generated at different positions of the pipe are gathered on the high flexural resistance supporting structure to offset the deflection deformation of the pipeline.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) Taking the highly flexurally resistant pipe support pipe assembly structure as an example, the present invention can generate three fulcrums for the pipe by sequentially arranging the first outer suspension component, the middle lower support component and the second outer suspension component, thereby avoiding supporting the pipe from a single fulcrum and reducing the flexible deformation of the pipe. At the same time, the two outer suspension pipes support the pipe upward in the front and rear, and the middle pull-back component is tightened by the flexural adjustment device to pull the pipe downward. The tension and pressure generated by the pipe at different positions are gathered on the highly flexurally resistant support structure. The support structure has a higher bending resistance than the pipe through cross-section reinforcement, thereby effectively offsetting the bending of part of the pipe and reducing the deflection deformation of the pipe at the support.

[0024] The same principle applies to the highly flexural resistant pipe hanger pipe assembly structure.

[0025] (2) The present invention can change the compression amount of the elastic support member by adjusting the nut, thereby changing the tension of the middle pull-back member or the pressure of the middle lower support member, thereby playing a role in adjusting the overall anti-bending effect of the bracket.

Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0037] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0038] Embodiment 1

[0039] At present, whether it is public pipelines, power pipelines or industrial pipelines, whether it is power station pipelines, chemical pipelines or municipal pipelines, the spacing of horizontal pipeline supports and hangers is limited. Because pipelines need to follow the corresponding support and hanger design specifications, when horizontal pipelines are continuously supported and hung, there are limit values for the stress and deflection of the pipelines due to the action of supports and hangers. According to this limit value, the maximum spacing of support and hanger settings to reach this limit value can be calculated. If the supports and hangers themselves can improve the stress of the pipeline and reduce the flexible deformation, the limit spacing of the supports and hangers can be larger.

[0040] Generally, compared with stress, deflection is the main limiting condition. Therefore, the present invention reduces the deflection by improving the flexible deformation of the pipeline.

[0041] Based on this, in one or more embodiments, a high-flexure-resistant pipe support pipe assembly structure is disclosed. Combining Figure 1 , specifically including: a high-flexure-resistant support structure body 4. On the upper surface of the high-flexure-resistant support structure body 4, a first outer support member 2-1, an intermediate pull-back member 3, and a second outer support member 2-2 are arranged in sequence along the axial direction of the pipeline 1. Combining FIGS. 2(a)-(b), the high-flexure-resistant support structure body 4 has an I-shaped cross-section, shaped like "工"; of course, those skilled in the art can also choose other cross-sectional forms, such as: H-shaped cross-section or double-channel steel cross-section, shaped like "H", "][".

[0042] The first outer support member 2-1 and the second outer support member 2-2 are respectively fixed on the upper surface of the high-flexure-resistant support structure body 4, and the intermediate pull-back member 3 is connected to the inside of the high-flexure-resistant support structure body 4 through a flexure-resistant adjustment device 5.

[0043] In this embodiment, combining Figure 3 , the flexure-resistant adjustment device 5 specifically includes: a first threaded rod 5-1 and a second threaded rod 5-1 respectively connected to the connecting members at the bottom of the intermediate pull-back member 3; the first threaded rod 5-1 and the second threaded rod 5-1 are symmetrically connected to the connecting members.

[0044] The first threaded rod 5-1 and the second threaded rod 5-1 respectively extend from the surface of the high-flexure-resistant support structure body 4 into the inside of the high-flexure-resistant support structure body 4. There is a through hole in the middle of the elastic support member 5-2 for the threaded rod 5-1 to pass through. An elastic support member 5-2 is provided on each threaded rod 5-1, and an adjusting nut 5-3 is arranged at the end. The elastic support member 5-2 is arranged between the high-flexure-resistant support structure body 4 and the adjusting nut 5-3. The elastic force of the elastic support member 5-2 can be adjusted through the adjusting nut 5-3, and thus the downward pulling force of the pull rod on the intermediate pull-back member 3 can be adjusted.

[0045] Referring to Figure 3, the threaded tie rod 5-1 sequentially passes downward through the holes on the upper surface of the high-flexure support structure body 4 and the middle through-hole of the elastic support member 5-2, and then is threadedly connected to the adjusting nut 5-3. The adjusting nut 5-3 abuts against the lower surface of the elastic support member 5-2. By adjusting its position on the tie rod, the degree of compressing the elastic support member 5-2 is adjusted, so as to achieve the purpose of adjusting the downward tension.

[0046] In this embodiment, the working method of the high-flexure pipe support pipe assembly structure is as follows:

[0047] The pipeline 1 is sequentially passed through the first outer support member 2-1, the middle pulling-back member 3 and the second outer support member 2-2 for support and fixation; the first outer support member 2-1 and the second outer support member 2-2 can support the pipeline 1 upward, and the middle pulling-back member 3 can pull the pipeline 1 downward. The pulling and pressing forces generated by the pipe part at different positions are concentrated on the high-flexure support structure. The support structure is strengthened by the cross-section and has a higher bending resistance than the pipeline 1, so that part of the bending of the pipeline 1 can be effectively offset, and the deflection deformation of the pipeline 1 at the support is reduced.

[0048] In this embodiment, the elastic support member 5-2 can be a spring or other suitable elastic structure. By adjusting the adjusting nut 5-3 and changing the compression amount of the elastic support body, the pulling force of the middle pulling-back member 3 can be changed, so as to play a role in adjusting the overall anti-flexure effect of the support.

[0049] Embodiment 2

[0050] In one or more embodiments, a high-flexure pipe hanger pipe assembly structure is disclosed. In combination Figure 4 , it includes: a high-flexure hanging structure body. Along the axial direction of the pipeline 1 on the lower surface of the high-flexure support structure body 4, a first outer hanging and pulling member 6-1, a middle lower support member 7 and a second outer hanging and pulling member 6-2 are sequentially arranged; in combination with FIGS. 5(a)-(b), the high-flexure support structure body 4 has an I-shaped cross-section, shaped like "工"; of course, those skilled in the art can also select other cross-section forms, such as: H-shaped cross-section or double-channel steel cross-section, shaped like "H", "][".

[0051] The first outer hanging and pulling member 6-1 and the second outer hanging and pulling member 6-2 are respectively fixed on the lower surface of the high-flexure support structure body 4, and the middle lower support member 7 is connected to the inside of the high-flexure support structure body 4 from the lower surface of the high-flexure support structure body 4 through the anti-flexure adjustment device 5.

[0052] In combination Figure 6 , the anti-flexure adjustment device 5 includes: a first threaded support rod and a second threaded support rod connected to the top connecting member of the middle lower support member 7; the first threaded support rod and the second threaded support rod are symmetrically connected to the connecting member;

[0053] Each threaded support rod is connected to the elastic support member 5-2, and there is a through hole in the middle of the elastic support member 5-2 for the threaded rod to pass through. The threaded support rod passes through the through hole on the bottom plate of the high-flexure-resistant support structure and the middle through hole of the elastic support member 5-2 in sequence, and then is threadedly connected with the adjustment nut 5-3. The adjustment nut 5-3 is against the upper surface of the elastic support member 5-2, and by adjusting its position on the pull rod, the degree of compression of the elastic support member 5-2 is adjusted, thereby achieving the purpose of adjusting the supporting force.

[0054] In this embodiment, a conventional support and hanger assembly 8 can be matched above the high-flexure-resistance hanger structure body to form various hangers for use.

[0055] The working method of the highly resistant pipe hanger pipe assembly structure of this embodiment is as follows:

[0056] The first outer lifting component 6-1 and the second outer lifting component 6-2 can lift the pipeline 1 upwards, and the middle lower supporting component 7 can support the pipeline 1 downwards. The tension and pressure generated at different positions of the pipe are gathered on the high-flexure-resistant lifting structure. The structure has a higher bending resistance than the pipeline 1 through cross-section reinforcement, thereby effectively offsetting the bending of part of the pipeline 1 and reducing the deflection deformation of the pipeline 1 at the bracket.

[0057] The elastic support body in this embodiment can be a spring or other suitable elastic structure. By adjusting the adjusting nut 5-3 and changing the compression amount of the elastic support body, the thrust of the middle lower support component 7 can be changed, thereby playing a role in adjusting the overall anti-flexing effect of the pipe assembly.

[0058] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
