Description

Technical Field

[0001] This utility model belongs to the field of silicon carbide load-bearing support technology, specifically relating to a square hole pad type silicon carbide column support frame. Background Technology

[0002] When cooling sintered silicon carbide under load, the support frame needs to be heat-resistant. Therefore, heat-resistant silicon carbide is mostly used as the support frame column. Multiple rectangular holes need to be made in the column for the crossbeam to pass through, forming a multi-layered support for the workpiece. However, when the crossbeam is installed through the rectangular holes, it is very easy for it to come into contact with the edges and corners of the rectangular holes (such as...). Figure 3 As shown in the attached diagram (C), friction or collision can damage the column. Damage to the rectangular hole can create a missing corner, affecting the level of the entire support and even making the column extremely prone to breakage. The column needs to be replaced in time. The column is a highly consumable part, and it is impossible to avoid protecting the edges and corners during use, which leads to increased production costs. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] The following is combined with Figure 1-10 This invention describes a specific embodiment of a square-hole pad-type silicon carbide column support frame, comprising:

[0034] A support column assembly 1 includes a support column 11, on which a plurality of crossbeam connecting holes 111 are formed. Support blocks 12 are provided within each crossbeam connecting hole 111. A contact portion 122 is formed at the top of each support block 12, and a crossbeam 13 is connected to the contact portion 122. The support column 11 supports the connecting crossbeam 13. The support blocks 12 are placed within the crossbeam connecting holes 111, with their bottoms connected to the crossbeam connecting holes 111 and their tops supporting the crossbeams 13. The crossbeam 13 is connected to the support column 11 and the crossbeam 13 by using the support pad 12 to provide indirect load support. When the crossbeam 13 is pulled out, the direct friction between the crossbeam 13 and the support pad 12 is replaced by the direct friction between the crossbeam 13 and the support column 11. This avoids wear on the corner C of the crossbeam connection hole 111, thereby improving the service life of the support column 11. By using the support pad 12, which is easy to replace and has low cost, as a wear part, the service life of the support column 11 is extended, and the production cost is reduced.

[0035] The connecting column group 21 includes a connecting column 21, which has several crossbeam connecting double holes 211. Support pads 12 are installed within the crossbeam connecting double holes 211. Similarly, the connecting column 21 operates on the same principle as the supporting column 11, utilizing the simple and low-cost support pads 12 as wear parts to extend the service life of the connecting column 21 and reduce production costs. The crossbeam connecting double holes 211 consist of two crossbeam connecting single holes 111 side-by-side on the width of the connecting column 21, connecting two crossbeams 13 on the same connecting column 21. This achieves a very narrow gap connection between two bearing plates 3, enabling continuous connection of multiple bearing plates 3. Furthermore, in existing brackets, when the supporting column 11 is slightly tilted, the crossbeam 13 only connects to one corner C of the crossbeam connecting single hole 111 or the crossbeam connecting double hole 211. The contact between the support column 111 and the connecting column 211 on the ground affects the stability of the support column 111 or the connecting column 211 and accelerates the wear of the corner C. In this solution, since the force point of the support pad 12 for supporting the crossbeam 13 is located at the center of the projection of the support column 11 on the ground, the support pad 12 provides support to the crossbeam in a point contact manner. The lower end face of the support pad 12 is always in contact with the lower end face of the single hole 111 or double hole 211 of the crossbeam connection, so that the support force provided by the pad 12 to the crossbeam 13 and the bearing plate 3 placed on the crossbeam 13 is evenly transmitted to the center of the support column 111 or the connecting column 211, so that the support column 111 or the connecting column 211 bears the workpiece evenly, thereby improving the stability of the overall support and preventing the crossbeam 13 from accelerating the wear of the corner of the single hole 111 or the double hole 211 of the crossbeam connection.

[0036] A bearing plate 3 is installed between the supporting column group 1 and the connecting column group 21 to form a gap. Both ends of the bearing plate 3 are connected to the tops of the crossbeams 13 on the supporting column group 1 and the connecting column group 21. A support pad 12 is placed on one of the single crossbeam connecting holes 111 opened on the supporting column 11, and the connecting crossbeam 13 is supported on the support pad 12. Support column group 1 is formed by installing supporting columns 11 on both ends of the crossbeam 13. Multiple supporting columns 11 can be connected to the crossbeam 13. A support pad 12 is placed on one of the double crossbeam connecting holes 211 opened on the connecting column 21, and the support pad... The crossbeam 13 is supported on block 12. Connecting columns 21 are installed at both ends of the crossbeam 13 to form a group 2 of connecting columns 21. To ensure the stability of the workpiece supported by the group 2 of connecting columns 21, multiple connecting columns 21 can be installed along the length of the crossbeam 13. A column support frame can be formed between the two groups of supporting columns 1. Bearing plates 3 can be installed on the crossbeam 13 on the two groups of supporting columns 1 to support silicon carbide. To improve the stability of the silicon carbide support and to achieve continuous installation of multiple bearing plates 3, the group 2 of connecting columns 21 can be connected between the two groups of supporting columns 1 to improve the load-bearing capacity of the silicon carbide and the stability of the support.

[0037] Please refer to Figures 1-2 As shown, several beam connecting holes 111 are equidistantly distributed along the height direction of the support column 11. The support column 11 has a support pad 14 at its bottom, which is fixedly connected to the bottom of the support column 11. The support pad 14 is used to improve the stability of the support column 11 on the ground. At the same time, the support pad 14 can be fixedly connected to the ground to avoid the swaying or tilting of the support column 11 after installation. By opening multiple beam connecting holes 111 along the height direction of the support column 11, on the one hand, multiple beams 13 can be connected on the support column 11 to realize multi-layer bearing of silicon carbide. On the other hand, the height of the bearing plate 3 on the support column 11 can be adjusted to adapt to the bearing requirements of different silicon carbide heights.

[0038] Please refer to Figure 1 As shown, several beam connecting double holes 211 are equidistantly distributed along the height direction of the connecting column 21. The bottom of the connecting column 21 is provided with a connecting pad 22, which is fixedly connected to the bottom of the connecting column 21. The connecting pad 22 is used to improve the stability of the connecting column 21 when placed on the ground. The height of the connecting column 21 and the several beam connecting double holes 211 equidistantly opened on it are adapted to the supporting column 11.

[0039] Please refer to Figures 2-5As shown, the width of the single hole 111 connecting the crossbeam and the double hole 211 connecting the crossbeam are greater than the width of the support pad 12. In this example, the width of the support pad 12 is slightly smaller than the width of the single hole 111 connecting the crossbeam and the double hole 211 connecting the crossbeam to ensure that the support pad 12 can pass through the single hole 111 connecting the crossbeam or the double hole 211 connecting the crossbeam.

[0040] In some embodiments, please refer to Figure 6 and Figure 8 As shown, the lower end face of the support pad 12 is flat, and the bottom of the support pad 12 directly fits into the single hole 111 or double hole 211 of the crossbeam connection. This avoids wear on the single hole 111 or double hole 211 of the crossbeam connection caused by the tilting movement of the crossbeam 13 during disassembly and installation, and can reduce wear on the corner C to a certain extent. In another embodiment, such as... Figure 5 , Figure 7 , Figure 9 , Figure 10 As shown, the bottom of the support pad 12 forms an installation part 121, which engages with the single hole 111 or the double hole 211 of the crossbeam connection. The installation part 121 is L-shaped, which can realize the mutual engagement between the bottom of the support pad 12 and the single hole 111 or the double hole 211 of the crossbeam connection. This can effectively prevent the support pad 12 from moving on the support column 11 or the connecting column 21, and eliminate the need to hold the support pad 12 when installing the crossbeam 13.

[0041] In some embodiments, please refer to Figures 5-9 As shown, the contact portion 122 is arc-shaped and protrudes outward toward the side away from the mounting portion 121. The contact portion 122 is used to support the connecting crossbeam 13. The arc shape of the contact portion 122 forms a bearing surface for the bearing connection of the crossbeam 13. The contact portion 122 provides stable bearing support for the crossbeam 13 and can reduce the contact area between the contact portion 122 and the crossbeam 13 to a certain extent, thereby reducing the sliding friction between the crossbeam 13 and the contact portion 122. This facilitates the movement of the crossbeam 13 on the contact portion 122. The protrusion height of the arc can be designed according to the opening height of the single hole 111 or the double hole 211 of the crossbeam connection and the height of the crossbeam 13.

[0042] In other embodiments, please refer to Figure 10 As shown, the top of the contact portion 122 is planar and parallel to the lower end face of the support pad 12. The planar area of ​​the contact portion 122 is smaller than the area of ​​the lower end face of the support pad 12. The planar nature of the contact portion 122 can increase the support bearing area of ​​the crossbeam 13.

[0043] Please refer to Figure 1 and Figure 4As shown, a rectangular groove 31 is provided on the bearing plate 3, and the rectangular groove 31 penetrates the bearing plate 3. Multiple rectangular grooves 31 are provided on the bearing plate 3. To a certain extent, this ensures that the bearing plate 3 meets the requirements for bearing silicon carbide, while reducing the self-weight of the bearing plate 3 and supporting the required bearing capacity of the column group 1 and the connecting column group 21.

[0044] Working principle of this utility model:

[0045] Assemble the support column group 1 and the connecting column group 21. During the assembly of the support column group 1, the support pad 14 is fixedly connected to the lower end of the support column 11 to improve the stability of the support column 11 when placed on the ground. A crossbeam 13 is erected between the two support columns 11. The support pad 12 is installed on the crossbeam connecting hole 111 at the same height of the two support columns 11, and the crossbeam 13 is erected on the support pad 12 to avoid bumping the corner C of the crossbeam connecting hole 111 when installing the crossbeam 13.

[0046] In the assembly of the connecting column 21 group 2, the connecting pad 22 is fixedly connected to the bottom of the connecting column 21. The support pad 12 is placed on the crossbeam connecting double hole 211 at the same height of multiple connecting columns 21, and the crossbeam 13 is installed on the support pad 12 to realize the installation of the connecting column 21 group 2.

[0047] A gap is formed between the two sets of support columns 1, and the two ends of the bearing plate 3 are respectively mounted on the crossbeams 13 on the two sets of support columns 1 to realize the erection of the column support frame. The bearing plate 3 can be continuously spliced ​​and erected. By using the connecting column 21 group 2 as the connecting column 21 between the two sets of support columns 1, multiple bearing plates 3 can be continuously spliced ​​to improve the load-bearing capacity and load-bearing stability of the silicon carbide workpiece.

[0048] Among them, the support pad 12 is used as a connector between the crossbeam connection single hole 111 or the crossbeam connection double hole 211 and the bearing plate 3. When the crossbeam 13 is installed and pulled on the support column 11 or the connecting column 21, the corner C on the column is avoided from being worn. The corner C only needs to bear the wear of the bearing material, which improves the service life of the crossbeam connection single hole 111 and the crossbeam connection double hole 211 to a certain extent.

[0049] In the first embodiment of the support pad 12, by setting its mounting part 121 in an L shape, it can be inserted and engaged with the single hole 111 or the double hole 211 of the beam connection during installation, thereby improving the stability of the support pad 12 on the column.

[0050] In another embodiment of the support pad 12, its top can be set to be arc-shaped or flat. The arc shape can reduce the contact area between the beam 13 and the support pad 12, thereby reducing the friction between the beam 13 and the support pad 12 when the beam 13 is pulled out. The flat shape can take into account the ease of pulling out while improving the stability of the connection between the beam 13 and the support pad 12, and preventing the two from moving.
