[0002] Pipelines meeting nuclear safety-grade seismic requirements play a crucial role in numerous industrial sectors, particularly in the nuclear industry, where safety performance is paramount. These pipelines transport a variety of critical media, and the stability and reliability of connections between them are directly related to the safe operation of the entire nuclear facility.

[0003] To ensure nuclear safety-grade seismic-resistant pipelines function properly in complex operating environments and conditions, they must be secured with fixtures. After securing, the pipelines undergo a series of critical operations, including heat treatment and weld flaw detection, to verify that their performance and quality meet stringent nuclear safety standards.

[0039] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0040] The core of the present invention is to provide a pipeline assembly fixing device with a simple structure, convenient assembly and disassembly, and can achieve stability and reliability of pipeline connection.

[0041] In order to enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Specifically, please refer to Figures 1-6 The present invention provides a pipeline assembly fixing device, including: a pipeline A, a first limit block assembly, an upper clamp 200, a lower clamp 300 and a support base 400.

[0043] A second stopper assembly is provided on the end surface of at least one of the upper clamp 200 and the lower clamp 300. Mounting blocks are provided on both sides of the upper clamp 200 and the lower clamp 300, respectively. The mounting blocks on the same side of the upper clamp 200 and the lower clamp 300 are connected by bolts. Specifically, an upper clamp mounting block 210 is provided on each side of the upper clamp 200, and a lower clamp mounting block 310 is provided on each side of the lower clamp 300. Mounting holes are provided in the upper clamp mounting blocks 210 and the lower clamp mounting blocks 310 at opposing positions. Bolts penetrate the mounting holes of the mounting blocks on the same side of the upper clamp 200 and the lower clamp 300 to achieve a locking connection.

[0044] The upper clamp 200 and the lower clamp 300 are arranged opposite to each other, and the space formed between the upper clamp 200 and the lower clamp 300 is used to constrain the pipe A. The space can just be mounted on the outer surface of the pipe A and fit with the outer surface of the pipe A to limit the shaking of the pipe A and achieve the effect of fixed constraint.

[0045] The support base 400 is connected to the lower clamp 300 to provide stable support.

[0046] The first limiting block assembly is fixedly connected to the outer surface of the pipe A and is used to cooperate with the second limiting block assembly to achieve circumferential and axial limiting of the pipe A.

[0047] During the assembly process, first fix the support base 400 in a suitable position, then place the pipe A fixed with the first limit block assembly on the upper surface of the lower clamp 300, and adjust the position between the pipe A and the lower clamp 300 to achieve preliminary matching.

[0048] Subsequently, the upper clamp 200 is fastened to the lower clamp 300. After the first limit block assembly on the pipe A can be exactly engaged with the second limit block assembly set on the end face of at least one of the upper clamp 200 and the lower clamp 300, the mounting seats on both sides of the upper clamp 200 and the lower clamp 300 are locked by bolts, so that the pipe A is firmly installed between the upper clamp 200 and the lower clamp 300, thereby realizing the circumferential and axial limitation of the pipe A.

[0049] Finally, the assembly of the entire pipeline assembly fixture is completed, and the pipeline A is firmly fixed.

[0050] The dismantling process of the entire pipeline assembly fixture is the same. By unscrewing the bolts on the mounting base and removing the upper clamp 200, the pipeline A can be quickly disassembled.

[0051] This solution provides a pipeline assembly type fixing device with a simple structure, which can be quickly assembled, and can achieve stability and reliability of pipeline connection, meeting the nuclear safety grade seismic resistance requirements.

[0052] In a specific embodiment, the first limiting block assembly and the second limiting block assembly each include at least one group.

[0053] Each set of first limiting block assemblies includes four first limiting blocks 100 , which are L-shaped protrusions. Each set of second limiting block assemblies includes four second limiting blocks 500 , which are rectangular protrusions.

[0054] Among them, the number of L-shaped protrusions is the same as that of rectangular protrusions. On the assembled pipe A, one side of the L-shaped protrusion abuts against one side of the corresponding rectangular protrusion, and the other side of the L-shaped protrusion abuts against the end face of the corresponding upper clamp 200 or lower clamp 300.

[0055] That is, the two side surfaces of an L-shaped protrusion are respectively abutted against the rectangular protrusion and the end face of the clamp, and a plurality of rectangular protrusions are provided on at least one of the upper clamp 200 and the lower clamp 300. The plurality of L-shaped protrusions cooperate with each other and work together to achieve positioning of the entire pipe A in both the circumferential and axial directions.

[0056] In order to further improve the force stability of the fixed connection, a set of second limit block assemblies are provided on the upper clamp 200 and the lower clamp 300, and two first limit blocks 100 are provided on both sides of the upper clamp 200 and the lower clamp 300 respectively.

[0057] Specifically, the first stopper assembly is welded to the outer surface of the pipe A. The second stopper assembly is integrally formed with the upper clamp 200 and / or the lower clamp 300. Preferably, the thickness of the second stopper assembly can be set to be consistent with the thickness of the upper clamp 200 and / or the lower clamp 300.

[0058] That is, the first stopper assembly on pipe A can be welded at the factory, and the second stopper assembly on the upper clamp 200 and the lower clamp 300 is also an integrally formed structure when shipped from the factory. Therefore, no welding operation is required at the assembly site, and bolt assembly can be performed directly.

[0059] In a specific embodiment, the shapes and sizes of the upper clamp 200 and the lower clamp 300 match and can be symmetrically arranged. The two are arranged relative to each other during assembly and connected by high-strength bolts. The inner walls of the upper clamp 200 and the lower clamp 300 fit the outer surface of the pipe A.

[0060] Generally, the main shapes of the upper clamp 200 and the lower clamp 300 can be designed as follows Figure 5 and Figure 6 The semicircular shell, the upper clamp 200 and the lower clamp 300 form a cylindrical body on the inner wall after assembly, which matches the outer wall of the pipe.

[0061] Furthermore, a plurality of first limiting blocks 100 are symmetrically arranged on the upper and lower sides of the pipe A, and a plurality of second limiting blocks 500 are symmetrically arranged on the upper clamp 200 and the lower clamp 300 .

[0062] In a specific embodiment, Figure 5 As shown, the support base 400 includes a bottom plate 410, a vertical bracket 420 and a reinforcing rib 430. The two ends of the vertical bracket 420 are respectively connected to the bottom plate 410 and the lower clamp 300. The reinforcing rib 430 connects the bottom plate 410 and the vertical bracket 420 to improve the connection strength.

[0063] The bottom plate 410 is provided with mounting holes, which are pre-buried bolt holes connected to the foundation. The bottom plate 410 is connected to the foundation through bolts.

[0064] The top of the vertical bracket 420 is connected to the lower clamp 300 by welding, bolting or other reliable means to fix the entire fixture to the corresponding base structure, provide solid support for the pipeline A, and ensure the stability and reliability of the entire device during use.

[0065] Of course, the support base 400 can also adopt other structural forms. For example, the support base 400 can be designed as a retractable base with adjustable height. By adjusting the height of the support base 400, the pipe-assembled fixture can be adapted to different process / fixing requirements at different heights. The specific structure of the retractable base is conventional and will not be described in detail here.

[0066] In a specific embodiment, the limit block assembly, the upper clamp 200, the lower clamp 300 and / or the support base 400 are made of high-temperature resistant alloy material to adapt to various temperatures, especially high-temperature environments, and meet nuclear safety-level seismic requirements.

[0067] The beneficial effects brought about by the technical solution provided by the present invention include:

[0068] 1. Modular assembly: The upper clamp 200, the lower clamp 300 and the support base 400 use standardized interfaces, eliminating the need for on-site welding and weld flaw detection, and increasing installation efficiency by more than 70%.

[0069] 2. Nuclear-grade safety: High-temperature resistant materials can meet fatigue and creep strength requirements at 800°C, meet seismic standards, and can withstand SL-2 (safe shutdown earthquake) level vibrations.

[0070] 3. Convenient maintenance: The clamp assembly consisting of a single upper clamp 200 and a lower clamp 300 can be disassembled and replaced independently without interrupting the operation of adjacent pipelines.

[0071] 4. Economical: Standardized factory manufacturing reduces costs and shortens production safety cycles.
