Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0037] The coal bunker room is an important part of the main plant of a thermal power plant, and its frame is usually used to support the coal hopper. The side coal bunker room of the main plant can effectively shorten the distance between the boiler and the steam turbine, and make full use of the space between the two furnaces, reduce the material consumption of the four major pipelines, and save costs. The side coal bunker of the million-unit unit occupies a small area and is high. The indoor single-side supports two coal hoppers, and the coal hopper stores 1,380 tons of coal. In order to meet the process requirements, the towering empty plant can only use a frame shear wall structure, and the coal hopper is suspended in the air of the plant. The coal hopper stores heavy coal, so a stable structure is required to transfer the coal hopper load to the foundation according to a clear path. For tall structures with high seismic forces, large wind loads, and heavy structural bearing, the structural layout and calculation are quite difficult. In addition, the coal hopper beam of the main plant of the million-unit unit needs to bear a coal hopper weighing about 900 tons. While carrying such a heavy coal hopper, it is also necessary to set a coal drop port in the coal seam. The prior art adopts a conventional integrally cast rectangular coal hopper beam. This cast-in-place concrete structure not only cannot fully meet the requirements of the coal outlet of the process professional coal hopper, but also is not conducive to the scattering of coal, and will cause coal to accumulate around the beam. This structure is not only inconvenient for the inspection and visit of process equipment and pipelines, but the excessively large cross-section of the first frame column will compress the space of the plant, which is not conducive to the layout of process equipment and pipelines.

[0038] In addition, the current support structure can also adopt 1. Conventional support type of coal hopper beam. That is, a herringbone support is designed in the middle of the coal hopper beam, and the other end of the support is supported on the beam-column node of the next frame floor. However, in this practice, the support occupies the space below the coal hopper layer. This method is suitable for the layout of four pipelines along the coal bunker, but not suitable for the side coal bunker layout of the million-unit unit. 2. At present, another row of frame columns can be set in the middle of the C and D column frame columns, extending all the way to the coal hopper layer, but it is also only suitable for the coal bunker. And adding another row of frame columns in the middle of the C and D column frame columns reduces the space of the plant and increases the difficulty of arranging pipelines for process professionals. And adding a row of frame columns increases the engineering volume of the foundation and superstructure, and the investment increases. 3. At present, the coal hopper beam can also be transformed into two sections, and the tension beam and inclined support are set up to directly transmit to the frame columns on both sides. However, this approach is suitable for the layout of coal bunkers. The main plant frame no longer has the joint function of the A and B row frame columns, and the eccentricity is not large, which will not greatly increase the column cross-section. However, the side coal bunker structure is high, and the single frame structure is difficult to calculate, which will increase the column cross-section, or use a shear wall structure, which will affect the process layout and increase investment.

[0039] Therefore, how to reasonably design the coal hopper support structure and related beam and column components so that the pipeline layout space is not restricted, and can ensure that people feel safe when passing under the coal hopper, and can also be used in areas with high earthquake intensity to meet the requirements of safety, practicality and economy, is a major problem in structural design. In response to this problem, the present application provides a coal hopper support structure that does not require the use of an integrally cast rectangular coal hopper beam to ensure the support effect of the coal hopper, thereby reducing the effective occupied space while facilitating the process requirements, and creating the most favorable conditions for the smooth layout of process equipment and pipelines.

[0040] Referring to FIG. 1 and FIG. 4 , an embodiment of the present application provides a coal hopper support structure, comprising a plurality of bracket assemblies 1, the plurality of bracket assemblies 1 are arranged at intervals along the X direction, and each two adjacent bracket assemblies 1 are connected by a connecting beam assembly 2. Specifically, the coal hopper 3 support structure also includes a plurality of connecting beam assemblies 2, and both ends of each connecting beam assembly 2 along the X direction are respectively connected to two bracket assemblies 1 arranged along the X direction in a one-to-one correspondence, so that the plurality of bracket assemblies 1 can be connected via the plurality of connecting beam assemblies 2. The coal hopper 3 can be installed in a space enclosed by the connecting beam assembly 2 and the two adjacent bracket assemblies 1.

[0041] Referring to FIG. 1 and FIG. 3 , the support assembly 1 includes a frame beam 11, a first cross beam 12, a second cross beam 13, a third cross beam 14 and two inclined columns 15. The first cross beam 12, the second cross beam 13 and the third cross beam 14 are sequentially arranged in the frame beam 11 from top to bottom. Specifically, the first cross beam 12, the second cross beam 13 and the third cross beam 14 are arranged in the frame beam 11 at intervals along the Z direction, and the second cross beam 13 is located between the first cross beam 12 and the third cross beam 14 along the Z direction. More specifically, the frame beam 11 includes two first frame columns 111 arranged at intervals along the Y direction, the first cross beam 12 is vertically arranged between the two first frame columns 111, the second cross beam 13 is vertically arranged between the two first frame columns 111, and the third cross beam 14 is vertically arranged between the two first frame columns 111.

[0042] The top ends of the two inclined columns 15 are connected to each other and are arranged in an inverted "V" shape on the first crossbeam 12. The bottom ends of the two inclined columns 15 are connected to the third crossbeam 14. The two inclined columns 15 are used to support the first crossbeam 12 connected to the coal hopper 3, without the need to use an integrally cast rectangular coal hopper 3 beam. The space between the two inclined columns 15 arranged in an inverted "V" shape can serve as a pedestrian passage for maintenance and visits. The space above the inclined columns 15 and the second crossbeam 13 can serve as a cable bridge passage, creating the most favorable conditions for the smooth arrangement of process equipment and pipelines. The second crossbeam 13 is passed through the two inclined columns 15 to enhance the stability between the inclined columns 15 and the second crossbeam 13, thereby enhancing the stability of the overall structure.

[0043] In summary, the coal hopper support structure of the present application ensures the supporting effect of the coal hopper 3 through the matching structure between the first crossbeam 12, the second crossbeam 13 and the two inclined columns 15. There is no need to use an integrally cast rectangular coal hopper 3 beam, which facilitates the process requirements while reducing the effective floor space. The two inclined columns 15 arranged in an inverted "V" shape can serve as a pedestrian passage for maintenance and visits, and the space between the inclined columns 15 and the upper part of the second crossbeam 13 can be used as a cable tray channel, creating the most favorable conditions for the smooth layout of process equipment and pipelines.

[0044] Referring to FIGS. 1 to 4 , in one embodiment, the top end of the inclined column 15 is connected to the middle of the first beam 12 to achieve uniform force between the first beam 12 and the two inclined columns 15. The bottom end of the inclined column 15 is connected to the third beam 14, and the distance between the bottom end of the inclined column 15 and the first frame column 111 is greater than the distance between the bottom end of the inclined column 15 and the middle of the third beam 14 to ensure that the inclined column 15 effectively supports the first beam 12.

[0045] Specifically, the top of the inclined column 15 is connected to the middle of the bottom surface of the first cross beam 12, and the bottom of the inclined column 15 is connected to the top surface of the third cross beam 14. The distance between the bottom end of the inclined column 15 and the first frame column 111 is equal to one third of the length of the third cross beam 14 along the Y direction. That is, the bottom ends of the two inclined columns 15 can divide the length of the third cross beam 14 along the Y direction into three equal parts. This distance can ensure the supporting effect of the inclined column 15 and the first cross beam 12, while providing enough space between the two inclined columns 15 arranged in an inverted "V" shape for inspection and visit.

[0046] Referring to FIGS. 1 to 4 , in one embodiment, the frame beam 11 further includes a second frame column 112 and a fourth cross beam 113, and the fourth cross beam 113 is disposed between the two first frame columns 111 to further improve the connection stability between the two first frame columns 111. The second frame column 112 is vertically disposed between the fourth cross beam 113 and the first cross beam 12 to achieve the connection between the fourth cross beam 113 and the first cross beam 12. The second frame column 112 and the top end of the inclined column 15 are spaced apart in the Z direction so that the inclined column 15 can provide support force to the second frame column 112, thereby ensuring the stability of the overall structure.

[0047] Specifically, during construction, the installation portion of the coal hopper 3 can be installed in the area enclosed by the first beam 12 and the fourth beam 113 of two adjacent bracket assemblies 1. The top and bottom of the second frame column 112 are respectively connected to the middle of the bottom surface of the fourth beam 113 and the middle of the top surface of the first beam 12, so that the second frame column 112 can evenly divide the area between the first beam 12 and the fourth beam 113 into two parts, so that two coal hoppers 3 can be installed at the same time.

[0048] 1 and 3, in one embodiment, the frame beam 11 further includes two frame pillars 114, which are spaced apart along the Y direction between the two first frame pillars 111, and the top ends of the two frame pillars 114 are connected to the bottom surface of the third beam 14. The third beam 14 is supported by the two frame pillars 114, thereby enhancing the stability between the third beam 14 and the frame beam 11.

[0049] Specifically, the top end of the frame support 114 and the bottom end of the inclined column 15 are spaced apart in the Z direction, so that the frame support 114 can bear the force given by the inclined column 15, thereby ensuring the stability of the overall structure.

[0050] More specifically, the bottom ends of the two frame pillars 114 and the bottom ends of the two first frame columns 111 are spaced apart along the Y direction so that when the frame beam 11 is installed, the bottom ends of the two frame pillars 114 and the bottom ends of the two first frame columns 111 can simultaneously contact the bearing surface (such as the ground, a tabletop, or the surface of other supporting bodies).

[0051] 1 and 3, in one embodiment, the frame beam 11 further includes two fifth cross beams 115, one end of the two fifth cross beams 115 is respectively disposed on the two frame pillars 114, and the other end of the two fifth cross beams 115 is respectively connected to the two first frame columns 111, so as to increase the stability between the frame pillars 114 and the first frame columns 111. Specifically, the fifth cross beam 115 is vertically disposed between the frame pillars 114 and the first frame columns 111.

[0052] Referring to FIG. 1 , FIG. 3 and FIG. 4 , in one embodiment, the connecting beam assembly 2 includes a first connecting beam 21, and the first connecting beam 21 is arranged on the first cross beam 12 of two adjacent bracket assemblies 1 to enhance the connection stability between the two adjacent bracket assemblies 1. Specifically, the first connecting beam 21 is vertically arranged between the two adjacent bracket assemblies 1, and the two ends of the second connecting beam 22 along the X direction are respectively connected to the first cross beam 12 of the two adjacent bracket assemblies 1. The extension line of the first connecting beam 21 intersects with the extension line of the inclined column 15, so that there is an intersection between the first connecting beam 21, the first cross beam 12 and the inclined column 15, thereby enhancing the stability of the overall structure.

[0053] Referring to FIG. 1 , FIG. 3 and FIG. 4 , in one embodiment, the connecting beam assembly 2 further includes two second connecting beams 22, and the two ends of the two second connecting beams 22 are respectively arranged on the two inclined columns 15 of the two adjacent bracket assemblies 1 to enhance the connection stability between the inclined columns 15 of the two adjacent bracket assemblies 1. Specifically, the second connecting beam 22 is vertically arranged between the two adjacent bracket assemblies 1, and the two ends of the second connecting beam 22 along the X direction are respectively connected to the inclined columns 15 of the two adjacent bracket assemblies 1. The extension lines of the two second connecting beams 22 intersect with the second cross beam 13, so that there is an intersection between the second connecting beam 22, the second cross beam 13 and the inclined column 15, thereby enhancing the stability of the overall structure.

[0054] Referring to Figures 1, 3 and 4, in one embodiment, the connecting beam assembly 2 further includes a plurality of third connecting beams 23, and the two ends of the plurality of third connecting beams 23 are respectively arranged on the two frame beams 11 of two adjacent bracket assemblies 1 to enhance the connection stability between the frame beams 11 of the two adjacent bracket assemblies 1. Specifically, the third connecting beam 23 is vertically arranged between the two adjacent bracket assemblies 1, and the two ends of the third connecting beam 23 along the X direction are respectively connected to the frame beams 11 of the two adjacent bracket assemblies 1.

[0055] Understandably, the support structure of the coal hopper is an important structural component in a thermal power plant. They bear the weight of the coal hopper and the pressure of the stored coal. The design of the coal hopper support structure needs to consider many factors, including the stability of the structure, the bearing capacity, the seismic performance, and the connection method with the main plant structure. When designing the coal hopper support structure, detailed force analysis and calculation are usually required to ensure the safety and reliability of the structure. This includes the overall force calculation of the coal hopper, the force characteristics analysis of the suspension connection point, the stability evaluation of the supporting steel beam, and the feasibility study of the coal hopper installation. For example, using finite element analysis software such as ANSYS to perform finite element model analysis of the coal hopper can obtain the stress and deformation of the coal hopper under different loads, thereby providing a basis for the design. In actual engineering, the design of the coal hopper support structure also needs to consider the convenience of construction and installation to ensure that the installation of the coal hopper will not have too much impact on the construction of the main plant. In addition, the support structure of the coal hopper also needs to consider the seismic design requirements to ensure the structural safety under extreme conditions such as earthquakes. The coal hopper support structure of the present application ensures the supporting effect of the coal hopper 3 through the matching structure between the first crossbeam 12, the second crossbeam 13 and the two inclined columns 15. There is no need to use an integrally cast rectangular coal hopper 3 beam, which facilitates the process requirements while reducing the effective floor space. The two inclined columns 15 arranged in an inverted "V" shape can serve as a pedestrian passage for maintenance and visits, and the space between the inclined columns 15 and the upper part of the second crossbeam 13 can be used as a cable tray channel, creating the most favorable conditions for the smooth layout of process equipment and pipelines.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
