Description

Technical Field

[0001] This invention relates to the field of pipeline support equipment, and in particular to a pipeline support device suitable for easily settled ground. Background Technology

[0002] Pipeline support devices play an indispensable role in the pipeline laying process. Thermal power plants have a large number of pipeline systems, including pipelines for transporting water, steam, fuel, etc. Pipeline support devices can effectively support these pipeline systems and ensure their stable operation. Especially under high temperature and high pressure conditions, pipeline support devices can bear the weight of the pipeline system, prevent the pipeline from sagging or deforming, and ensure the safety of the pipeline.

[0003] However, ground settlement has a significant impact during the use of pipeline support devices. Ground settlement may cause the pipeline support points to become unstable or even suspended. Suspended support devices not only fail to support the pipeline but also increase the load on the pipeline, which can affect the stability of the pipeline system and may even lead to safety issues such as pipeline rupture or leakage. Currently, there are support devices that can detach the pipeline on their own as the ground settles, but in cases of large ground settlement differences, there is a risk of the support device falling and being damaged.

Detailed Implementation

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0021] Example 1 Reference Figures 1-11 This is the first embodiment of the present invention, which provides a pipe support device suitable for easily subsided ground. Specifically, it includes a pipe fixing mechanism 100, which includes an upper fixing component 101 and a lower fixing component 102 disposed below the upper fixing component 101; a first support mechanism 200, which includes a first support column component 201 disposed below the lower fixing component 102 and adjustment components 202 disposed on both sides of the support column component 201; and a second support mechanism 300, which includes a second support column component 301 disposed outside the first support column component 201 and a base plate component 302 disposed below the second support column component 301, the base plate component 302 being slidably disposed below the lower fixing component 102.

[0022] Furthermore, the upper fixing component 101 includes a first fixing ring 101a and a first connecting plate 101b fixed at both ends of the first fixing ring 101a; the lower fixing component 102 includes a second fixing ring 102a, a second connecting plate 102b fixed at both ends of the second fixing ring 102a, and a first connecting seat 102c integrally fixed at the lower part of the second connecting plate 102b.

[0023] It should be noted that by bolting the first connecting plate 101b and the second connecting plate 102b, the first retaining ring 101a and the second retaining ring 102a can be used to lock the pipe.

[0024] Preferably, the first support assembly 201 includes a second connecting seat 201a that fits against the lower part of the first connecting seat 102c, and a first support 201b fixed to the lower part of the second connecting seat 201a; the adjustment assembly 202 includes an adjustment seat 202a fixed to the lower part of the second connecting seat 201a; the second support assembly 301 includes a support shell 301a fixed to the upper part of the base plate assembly 302, a second support 301b slidably disposed on the upper part of the support shell 301a, and a third spring 301c disposed in the support shell 301a; the base plate assembly 302 includes a base plate 302a and a guide rod 302b fixed to the upper part of the base plate 302a.

[0025] In this embodiment, after a small ground subsidence, the second support assembly 301 and the base plate assembly 302 can change the state between the adjustment assembly 202 and the first support assembly 201 to compensate for the ground subsidence. After a large ground subsidence, the first support mechanism 200 and the second support mechanism 300 can be integrated into one unit and detached from the pipe fixing mechanism 100 to avoid hanging on the pipe and causing a burden on the pipe. After a large and rapid ground subsidence, the second support mechanism 300 can support and buffer the first support mechanism 200, reducing the probability of damage to the first support mechanism 200.

[0026] Example 2 Reference Figures 1-13 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] Specifically, the first connecting plate 101b has a first guide hole W-1 in the middle; the second connecting plate 102b has a second guide hole W-2 in the middle; the first connecting seat 102c has an insertion hole W-3 at the bottom and a sliding cavity W-4 connected to the top of the insertion hole W-3.

[0028] Furthermore, the second connecting seat 201a is provided with a sliding groove W-5 communicating with the lower part of the insertion hole W-3, and a slot W-6 located in the middle of the sliding groove W-5; the first support assembly 201 also includes a spring plate 201c fixed to the lower part of the end of the second connecting seat 201a, a sliding hook 201d slidably disposed in the sliding groove W-5, and a first spring 201e whose two ends respectively contact the spring plate 201c and the sliding hook 201d.

[0029] Furthermore, the first support column 201b is provided with support holes W-7, and there are no less than three sets of support holes W-7 arranged vertically; the sliding hook 201d includes a first locking plate 201d-1 slidably disposed in the sliding cavity W-4, a sliding rod 201d-2 fixed to the lower part of the first locking plate 201d-1 and slidably disposed in the insertion hole W-3 and the sliding groove W-5, a second locking plate 201d-3 fixed to the sliding rod 201d-2 and slidably disposed in the locking groove W-6, and a hook rod 201d-4 fixed to the bottom of the sliding rod 201d-2.

[0030] It should be noted that the second card plate 201d-3 can only slide horizontally in the card slot W-6. Therefore, the entire sliding hook 201d and the second connecting seat 201a can only slide horizontally and cannot slide vertically. When the first card plate 201d-1 is in the sliding cavity W-4, the entire first support mechanism 200 can be hung on the lower part of the first connecting seat 102c through the first card plate 201d-1. When the first card plate 201d-1 is in the insertion hole W-3, the entire first support mechanism 200 will fall under gravity because the bottom of the first card plate 201d-1 loses support.

[0031] Furthermore, the adjusting seat 202a has a support plate hole W-8 facing the support hole W-7, and a spring block 202a-1 is fixed in the middle of the support plate hole W-8; the adjusting assembly 202 also includes a support plate 202b slidably disposed in the support plate hole W-8, and a second spring 202c whose two ends are respectively fixed on the support plate 202b and the spring block 202a-1.

[0032] It should be noted that the length of the support plate 202b is longer than the distance between the first pillar 201b and the adjusting seat 202a. After the support plate 202b is compressed, it can ensure that the other end is still in the support plate hole W-8 while one end slides into the support hole W-7, thereby making the support plate 202b stable when the side wall is compressed.

[0033] Furthermore, a limiting block 301a-1 is fixed to the top of the inner wall of the support shell 301a; the second pillar 301b is provided with a first pillar hole H-1 penetrating the middle of the second pillar 301b, a limiting hole H-2 located at the bottom of the side wall of the second pillar 301b, and a hook hole H-3 located at the top of the side wall of the second pillar 301b, and the top of the second pillar 301b is chamfered; the first pillar 201b is inserted into the first pillar hole H-1, and the top of the first pillar 201b contacts the bottom of the second connecting seat 201a; the limiting block 301a-1 is slidably disposed in the limiting hole H-2.

[0034] Preferably, the upper end of the guide rod 302b is slidably disposed in the first guide hole W-1 and the second guide hole W-2; the guide rod 302b includes a pressing section 302b-1, a sliding section 302b-2 and a connecting section 302b-3, the pressing section 302b-1 is located above the sliding section 302b-2 and is slidably disposed in the first guide hole W-1 and the second guide hole W-2, the sliding section 302b-2 is located above the connecting section 302b-3, and the connecting section 302b-3 is fixed to the upper part of the base plate 302a; the pressing section 302b-1 is closer to the adjusting seat 202a than the connecting section 302b-3.

[0035] In this embodiment, after the pipe support device suitable for easily settled ground is installed on the pipe, such as Figure 1 As shown, in the state where all support plates 202b are not compressed by the compression section 302b-1, the second pillar 301b supports the pipe fixing mechanism 100 by pressing against the bottom of the second connecting seat 201a. After ground settlement, the ground height decreases relative to the pipe, and the base plate 302a will decrease along with the ground height, pulling the guide rod 302b downwards. When the guide rod 302b slides down, the sliding section 302b-2 will first compress the top support plate 202b, causing the support plate 202b to overcome the elastic force of the second spring 202c and move towards the support hole W- 7. Sliding: During the sliding process of the support plate 202b, the end of the support plate 202b near the support hole W-7 will press the top chamfer of the second pillar 301b, causing the top of the second pillar 301b to slide downward a certain distance against the elastic force of the third spring 301c; After the support plate 202b presses down the second pillar 301b and extends into the rear support hole W-7, the second pillar 301b can support the first support mechanism 200 by pressing against the lower part of the support plate 202b, thereby supporting the pipe fixing mechanism 100. The multi-layer support plate 202b can compensate for the height difference caused by ground settlement.

[0036] It should be noted that after significant ground subsidence, to the point that the multi-layer support plate 202b could not compensate for the height difference caused by the subsidence, the second support column 301b had slid down to the bottom of the lowest support plate 202b. As the second support column 301b continued to slide down, the hook rod 201d-4 would slide into the hook hole H-3 under the elastic force of the first spring 201e. During this process, the first locking plate 201d-1 slid from the sliding cavity W-4 into the insertion hole W-3. The first locking plate 201d-1 could no longer be attached to the bottom of the first connecting seat 102c, and the bottom of the first connecting seat 102c separated from the top of the second connecting seat 201a. After this, the first support mechanism 200 as a whole was supported by the sliding hook 201d on the second support column 301b, and the first support mechanism 200 as a whole no longer burdened the pipeline when it could not support it.

[0037] It should also be noted that when the ground subsides significantly and rapidly, the second support mechanism 300 and the first support mechanism 200, supported by the sliding hook 201d on the second pillar 301b, fall together. When they fall onto the subsided ground, the base plate 302a will contact the ground first. Due to the larger area of ​​the base plate 302a, the probability of damage to the base plate 302a upon falling to the ground is much lower than the probability of damage to the lower part of the first support mechanism 200 upon falling to the ground. At the same time, when the second support mechanism 300 and the first support mechanism 200 fall to the ground, the third spring 301c supporting the second pillar 301b can provide cushioning for the second pillar 301b and the first support mechanism 200 supported on the second pillar 301b, further reducing the probability of damage to the first support mechanism 200 and ensuring that the pipe support device suitable for easily subsided ground can be reused after being recovered.

[0038] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
