Description

Technical Field

[0001] This utility model patent belongs to the field of pipeline installation technology in metallurgical engineering, specifically a fixing and limiting device for installing small-diameter energy medium pipelines such as heat, gas, and water supply and drainage. Background Technology

[0002] In the field of metallurgical engineering, various smelting systems need to transport various gases, liquids, and solids, which are often transported through pipelines. Therefore, various pipeline networks are an important component of metallurgical engineering. The fixing or limiting of pipelines is often achieved by installing pipe supports. For large-diameter energy medium pipelines (D > 500mm), the industry-standard curved pipe supports are generally used for support and fixing. These supports are firmly fixed and provide uniform support to the pipeline, hence their widespread application. However, for small-diameter energy medium pipelines (D ≤ 500mm), due to their large curvature and small load, using the same type of pipe support would be difficult to fabricate on-site, and it would be impossible to ensure that the curvature perfectly fits the pipeline. Currently, for small-diameter energy medium pipelines, the industry generally uses the following two pipe support fixing methods: Method one involves using channel steel as pipe supports. While a common fixing method, this approach has several drawbacks. For pipes of different diameters, the channel steel often cannot perfectly fit, requiring the channel steel to be cut to fit the pipe, significantly increasing on-site work. Furthermore, fixing the channel steel pipe supports often requires pre-installation at the support points. On long pipelines, it's impossible to ensure all supports are in a straight line, leading to significant errors after installation and preventing proper pipe alignment. This causes considerable difficulty in on-site installation and requires prolonged use of hoisting equipment for positioning. Therefore, construction companies are often reluctant to use this method.

[0003] Method 2 involves using pipe clamps to secure the energy medium pipeline. This method is generally used for smaller diameter pipelines, such as those less than 300mm, and works well. However, for larger diameter pipelines, such as those between 300 and 500mm, pipe clamps often cannot effectively restrain the pipeline, and they are generally used for sliding pipe supports. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a fixed limiting device for small-diameter energy medium pipelines in smelting systems. Unlike existing construction methods, it allows the fixed limiting device to be installed after the pipeline is in place, greatly improving the convenience of construction by adjusting the construction sequence.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A fixing and limiting device for a small-diameter energy medium pipeline in a smelting system includes a supporting steel beam and a first equal-legged angle steel and a second equal-legged angle steel. Both equal-legged angle steels have a pointed end and a back end. The energy medium pipeline is installed on the supporting steel beam. The contact point between the supporting steel beam and the energy medium pipeline forms a supporting position. The two equal-legged angle steels are located on both sides of the energy medium pipeline. One back end of each equal-legged angle steel is pressed against the energy medium pipeline. The pointed ends of the two equal-legged angle steels and the pointed ends of the equal-legged angle steels face downwards. One pointed end is welded and fixed to the supporting steel beam. The diameter D of the energy medium pipeline is ≤ 500 mm.

[0006] Furthermore, two equal-sided angle steels are symmetrically arranged on both sides of the support position of the supporting steel beam, and the groove formed by the two equal-sided angle steels and the supporting steel beam constitutes a pipe support for fixing the energy medium pipeline.

[0007] Furthermore, the outer limbs of the equilateral angle steel are welded to the supporting steel beam, and the weld height can be 6-8mm.

[0008] Furthermore, the limbs of the equilateral angle steel are welded to the energy medium pipeline to form a fixed pipe support.

[0009] Furthermore, the back of the equilateral angle steel is pressed against the energy medium pipeline without welding, forming a sliding pipe support.

[0010] Furthermore, the length L of the equilateral angle steel ranges from 150mm to 300mm.

[0011] Furthermore, the supporting steel beam includes an upper flange and a lower flange, and stiffening ribs are provided between the upper and lower flanges below the vertical center line of the energy medium pipeline.

[0012] Furthermore, the stiffening ribs are made of t=8mm steel plates, which are welded to the upper and lower flanges and the web.

[0013] The beneficial effects of this utility model are as follows: This utility model provides an energy medium pipeline fixing and limiting device that utilizes a support structure to form a groove-shaped pipe support between the support surface and the pipeline. Unlike existing pipe support construction methods, this device can be installed after the pipeline is in place, eliminating the need for hoisting equipment during installation and avoiding prolonged occupation of such equipment. Furthermore, it eliminates the need to adjust the installation accuracy of the pipe support during pipeline installation to ensure the correct pipeline position, significantly reducing construction difficulty. Compared to traditional arc-shaped or channel steel pipe supports, it is simpler to manufacture, easier to install, and saves materials. It also reduces initial stress on the pipeline caused by installation errors, thus minimizing impacts on pipeline performance. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings: To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0017] Please see Figures 1 to 3 A fixing and limiting device for a small-diameter energy medium pipeline in a smelting system includes a supporting steel beam 2 and two equal-sided angle steels 1. Each of the two equal-sided angle steels 1 has a pointed end 4 and a back end 5. An energy medium pipeline 3 is installed on the supporting steel beam 2. The contact point between the supporting steel beam 2 and the energy medium pipeline 3 forms a support position. The two equal-sided angle steels 1 are located on both sides of the energy medium pipeline 3. One back end of each equal-sided angle steel 1 is pressed against the energy medium pipeline 3, and the pointed ends 4 of the two equal-sided angle steels 1 face downwards. One pointed end is welded and fixed to the supporting steel beam 2. The diameter D of the energy medium pipeline 3 is ≤ 500 mm. This invention cleverly utilizes the steel supporting beam or steel support point to form a pipe support, while adjusting the installation sequence of the pipeline and the pipe support, reducing construction difficulty, improving installation accuracy, and reducing the initial stress on the pipeline caused by pipe support installation errors, thereby improving the pipeline's working performance.

[0018] See Figure 1 Install small-diameter (D≤500mm) energy medium pipelines on supporting steel beam 3 and adjust them to the designed position to ensure that all pipelines are connected and in place.

[0019] In one embodiment of this utility model, a set of equilateral angle steel 1 with its limbs pointing downwards is placed below the energy medium pipeline 3, and is pressed against the pipeline 3 from both sides inwards. The length of the equilateral angle steel 1 is 150mm to 300mm, with L=150mm being optional. The material is Q235B, and its model can be selected according to the diameter of the pipeline. For example, when the diameter is 250mm, the model L63X6 equilateral angle steel is selected. Figure 2 In the middle, the length of the equilateral angle steel is L=150mm, and the distance b is adjusted according to the pipe diameter to achieve the state where the back of the limb is tightly against the pipe.

[0020] The groove formed by the equilateral angle steel 1 and the supporting steel beam 2 constitutes a pipe support for fixing the pipeline. Then, the outer limbs of the equilateral angle steel 1 are welded on-site to the steel supporting beam 3, with a weld height of 6-8 mm. Stiffening ribs 6 are installed on the supporting steel beam below the vertical center line of the pipeline; these stiffening ribs can be made of t=8 mm steel plates. The supporting steel beam 3 includes an upper flange and a lower flange, and the steel plate 6 is welded to the upper and lower flanges and the web.

[0021] The back of the equilateral angle steel leg can be welded to the pipe or not, depending on the process requirements, thus forming a fixed pipe support or a sliding pipe support.

[0022] From the current industry status and technological background, for small-diameter energy medium pipelines, this utility model adopts a simple and feasible method, different from existing pipe support construction methods. It allows the pipe support to be installed and fixed after the pipeline is in place, greatly improving construction convenience through the adjustment of the construction sequence. At the same time, it avoids the initial stress caused by the installation accuracy errors of traditional pipe supports during pipeline installation and subsequent use, thus preventing the pipeline from affecting its normal working performance.

[0023] The above description is merely an embodiment of the invention's technical content. Any modifications or variations made by those skilled in the art using this invention are within the scope of the invention's claims, and are not limited to those disclosed in the embodiments.
