[0003] In common commercial machines, only the ends of the beams are used to connect to the columns. This design is prone to stress concentration and deformation of the columns when subjected to heavy loads, resulting in insufficient structural strength and stability.

[0004] In the existing technology, structures such as stainless steel corner brackets are added to increase the structural strength between the columns and beams. However, adding stainless steel corner brackets will still lead to stress concentration problems, and since structures such as corner brackets are exposed outside the columns and beams, they are prone to rust and have an unsightly appearance.

DETAILED DESCRIPTION

[0045] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0046] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0047] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0048] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Example 1

[0050] like Figure 1 and Figure 8 As shown, the utility model provides a column 1-beam connection structure, including a column 1, a beam structure 2 and a first reinforcing rib 3, wherein at least one bending surface is formed on the inner side of the column 1; the beam structure 2 is connected to the column 1; there are two first reinforcing ribs 3; specifically, the first reinforcing rib 3 is arranged on the inner side of the column 1 and is used to connect the column 1 and the beam structure 2; the first reinforcing rib 3 is distributed on both sides of the beam structure 2; the first reinforcing rib 3 includes a first fitting surface 31 and a second fitting surface 32, the first fitting surface 31 is suitable for fitting with the bending surface on the inner side of the column 1; the second fitting surface 32 is suitable for fitting with the upper surface or lower surface of the beam structure 2. In this solution, by adding the first reinforcing rib 3 and fitting the first reinforcing rib 3 tightly with the column 1 and the beam structure 2, the overall stability and torsional resistance of the structure can be enhanced. This design can effectively disperse and withstand loads from different directions, ensure the stability of the structure, and effectively improve the original concentrated stress phenomenon.

[0051] It should be noted that, in this embodiment, the position of the second fitting surface 32 of the first reinforcing rib 3 is related to the position of the first reinforcing rib 3. Specifically, when the first reinforcing rib 3 is above the beam structure 2, the bottom surface of the first reinforcing rib 3 is the second fitting surface 32; when the first reinforcing rib 3 is below the beam structure 2, the top surface of the first reinforcing rib 3 is the second fitting surface 32.

[0052] It should be noted that in this embodiment, there are four columns 1; the crossbeam structure 2 is specifically arranged in a "mouth" shape. A supporting crossbeam is also provided in this embodiment. The supporting crossbeam is disposed within the crossbeam structure 2 to further enhance the stability of the crossbeam structure 2. In this embodiment, the crossbeam structure 2 is specifically formed by two crossbeams cross-jointed. The four columns 1 are disposed at the four corners of the crossbeam structure 2, and the extension plates 21 are also disposed at the four corners of the crossbeam structure 2.

[0053] like Figure 2 and Figure 3 As shown, further, a connection hole 4 is provided on the first reinforcing rib 3 , and the first reinforcing rib 3 is bolted to the column 1 through the connection hole 4 .

[0054] Furthermore, to enhance the stability of the column 1, a second reinforcing rib 30 is provided. There are multiple second reinforcing ribs 30, which are arranged on the inner side of the column 1. The number of second reinforcing ribs 30 can be increased or decreased according to actual needs. It should be noted that the shape of the second reinforcing rib 30 can be the same as that of the first reinforcing rib 3. If the shape of the second reinforcing rib 30 is the same as that of the first reinforcing rib 3, the second reinforcing rib 30 only mates with the inner curved surface of the column 1 via the first mate surface 31. Specifically, the second reinforcing ribs 30 are arranged at intervals along the extension of the column 1 and can be fixedly connected to the column 1 by welding or bonding. If the shape of the second reinforcing rib 30 is different from that of the first reinforcing rib, the second reinforcing rib 30 can be in the form of a protrusion, i.e., a diamond-shaped protrusion is formed on the column 1. By adding the diamond-shaped protrusion, the thickness of the column 1 is increased, thereby increasing the load-bearing capacity of the column 1 and achieving a reinforcement effect. As an alternative embodiment, the second reinforcing rib 30 can also be a combination of the two forms or a single form.

[0055] Furthermore, two first reinforcing ribs 3 are provided on each of the main bodies; the two first reinforcing ribs 3 on each of the main bodies are respectively provided on both sides of the beam structure 2 .

[0056] Furthermore, an extension plate 21 is provided at the end of the crossbeam structure 2, extending along the direction of the column 1. Mounting holes 22 are provided on the extension plate 21, which is bolted to the column 1 through these mounting holes. This solution increases the contact area between the crossbeam structure 2 and the column 1, enhancing the overall stability and torsional resistance of the structure. This design effectively disperses and absorbs loads from different directions, ensuring structural stability and effectively reducing the previously observed stress concentration.

[0057] It should be noted that, in this embodiment, the crossbeam structure 2 can be composed of four crossbeams integrally formed. As an alternative implementation, the crossbeam structure 2 can also be composed of four crossbeams fixedly connected to the columns 1 respectively.

[0058] like Figure 2As shown, further, in this embodiment, the crossbeam structure 2 can be composed of four crossbeams integrally formed. Through the integrally formed design, the crossbeam structure 2 can be installed once, and the assembly of the crossbeam structure 2 is also provided with a fixing plate 9, which is suitable for being fixedly connected to the crossbeam structure 2; in this embodiment, the fixing plate 9 is fixedly connected to the crossbeam structure 2 by welding. Specifically, the fixing plate 9 includes a side plate and a bottom plate, wherein welding holes are provided on both the side plate and the bottom plate, wherein the side plate is fixedly connected to the crossbeam structure 2 by welding, the bottom plate is perpendicular to the side plate, and is welded and fixed to the extension plate 21 at both ends of the bottom plate; the specific fixing method includes welding or bonding, etc. As an alternative embodiment, the fixing plate 9 and the extension plate 21 can also be integrally formed. It should be noted that the integrally formed method of the fixing plate 9 and the extension plate 21 is simpler in installation steps than the split fixing method, and is convenient for on-site installation.

[0059] like Figure 9 and Figure 10 As shown, as a replaceable embodiment, when the beam structure 2 consists of four beams fixedly connected to the columns 1 respectively, the fixing plate 9 consists of a first connecting plate, a second connecting plate and a third connecting plate, wherein the first connecting plate is welded and fixedly connected to the inner side of the beam, the second connecting plate and the end of the first connecting plate are vertically connected to each other, and the second connecting plate is welded and fixedly connected to the inner side of the end of the beam, the third connecting plate is an L-shaped plate, the long side of the third connecting plate is welded and connected to the inner side of the bottom of the beam, and the short side of the third connecting plate is suitable for connection to the extension plate 21. The beam structure 2 consists of four beam structures 2, which is convenient for later replacement or maintenance of the internal system. When an internal system needs to be replaced, it is only necessary to dismantle the adjacent beams, which greatly reduces the later maintenance cost. In this embodiment, the fixing plate 9 and the extension plate 21 are integrally formed; further, in order to increase the stability of the overall structure, a triangular protrusion is provided between the first connecting plate and the second connecting plate. By providing the triangular protrusion, the stability of the connection between the first connecting plate and the second connecting portion can be increased. Furthermore, strip protrusions are provided on the surface of the third connecting plate and the surface of the baffle 23. By providing the strip protrusions, the stability between the fixing plate 9 and the extension plate 21 can be increased. By providing the strip protrusions and the triangular protrusions, the overall structure is not easily changed, thereby ensuring the stability of this solution.

[0060] It should be noted that, further, the column 1 includes a main body and a folded edge; the folded edge is arranged on both sides of the main body; the folded edge is arranged at an angle to the main body; the folded edge is extended in a direction away from the main body; and the folded edge is suitable for fitting with the surface of the extension plate 21. In this solution, a supporting beam is also provided, and the supporting beam is provided inside the beam structure 2. By providing the supporting beam, the stability of the beam structure 2 can be further increased. In this solution, the beam structure 2 is specifically formed by two beams cross-lapped, and in order to ensure the stability of the supporting beam, a central column 1 is also provided at the position where the supporting beam is connected to the beam structure 2. The central column 1 supports the beam structure 2 and the supporting beam at the same time. Four of the columns 1 are respectively provided at the four corners of the beam structure 2, and the extensions are also provided at the four corners of the beam structure 2. In this solution, two extension plates 21 are provided at each corner, and the two extensions are respectively fitted with the folded edges provided on the column 1. The folded edge also has through holes corresponding to the mounting holes 22. The extension portion is connected to the folded edge by bolts. As an alternative, a snap-fit ​​connection or other detachable connection can also be used. It should be noted that there are eight extension plates 21, with two provided at each corner of the crossbeam structure 2.

[0061] It's important to note that, compared to the original crossbeam design, the four beams are now connected as a single piece. This allows each component to be prefabricated into standard parts at the factory, reducing the need for on-site welding and cutting. On-site installation requires only simple bolting and assembly, significantly reducing construction time and effort. The assembly sequence can be altered, allowing the fins to be installed before column 1, preventing scratches on the fins during the installation process.

[0062] Furthermore, the crossbeam structure 2 also includes a baffle 23, which is arranged on one side of the extension plate 21, and the baffle 23 abuts against the folded edge; it should be noted that the baffle 23 is specifically bent ninety degrees with the extension portion, and precise positioning can be achieved through the abutment between the baffle 23 and the folded edge. Through the abutment, the bolt holes can be quickly overlapped, which optimizes the construction process and improves production efficiency.

[0063] Furthermore, a hoisting hole 5 is provided on the column 1, specifically, on the folded edge. The hoisting hole 5 allows the entire frame to be hoisted along with the column 1, simplifying the hoisting operation and improving production efficiency and structural stability. The entire frame can be quickly hoisted and positioned, optimizing the construction process, reducing construction costs, and improving production efficiency. The hoisting riveting device provides additional stability, preventing the frame from tilting or shaking, ensuring safety during the hoisting process.

[0064] Example 2

[0065] like Figure 4 and Figure 7As shown, a heat pump chassis includes the column 1 crossbeam connection structure described in Example 1, and also includes a water receiving tray assembly 6, a fin heat exchanger assembly 7 and a partition assembly 8. The water receiving tray assembly 6 is covered on the crossbeam structure 2; the fin heat exchanger assembly 7 has at least two groups; the fin structure 71 is arranged on the water receiving tray assembly 6; and the partition assembly 8 is arranged between adjacent fin heat exchanger assemblies 7.

[0066] Furthermore, the water receiving tray assembly 6 is provided with fixing holes, through which the water receiving tray assembly 6 is connected to the crossbeam structure 2. It should be noted that in this solution, there are four water receiving tray assemblies 6, which can completely cover the entire crossbeam structure 2.

[0067] like Figure 5 As shown, further, the fin heat exchanger assembly 7 includes two fin structures 71, and the two fin structures 71 are fixedly connected by a fixing plate 9. Figure 6 As shown, the two fin structures 71 are pre-connected by a fixing plate 9. The two pre-connected fin structures 71 are then fixedly connected to the water receiving tray assembly 6.

[0068] Furthermore, a sealing plate 10 is provided, and the sealing plate 10 is provided between the two fin structures 71 .

[0069] It should be noted that the installation process of the heat pump chassis in this solution includes the following steps: dividing the heat pump chassis into an upper part and a lower part, first installing the upper part and the lower part separately, and then assembling the upper part and the lower part;

[0070] During the installation of the upper portion, first install the finned heat exchanger assembly 7 onto the water tray assembly 6, then install the column 1 and fan assembly onto the water tray assembly 6. Column 1 is installed vertically at the corner of the water tray assembly 6, and the fan assembly is installed above the finned heat exchanger and connected to the upwardly extending end of the column 1. This arrangement, installing the finned heat exchanger on the water tray first and then the column 1, prevents the column 1 from scratching the finned heat exchanger when hoisting it.

[0071] The lower part includes a base assembly. When the upper part and the lower part are assembled, the base assembly is installed below the water tray assembly 6 and connected to the downwardly extending end of the column 1. Specifically, the base assembly and the corner column 1 can be connected by bolts or welding.

[0072] It should be noted that during the upper connection process, the crossbeam structure 2 is composed of four surrounding crossbeams and two central crossbeams. The two central crossbeams are connected using an overlapping method, with one crossbeam overlapping the other, to enhance the stability and load-bearing capacity of the structure. A central column 1 is also installed at the location where the supporting crossbeams connect to the crossbeam structure 2. The central column 1 supports both the crossbeam structure 2 and the supporting crossbeams, thereby enhancing the stability and load-bearing capacity of the structure.

[0073] It should be noted that during the upper connection process, multiple fin structures 71 are sequentially connected on the water receiving tray assembly 1. With this arrangement, multiple fin structures 71 can be used to perform heat exchange for multiple systems. Specifically, in this embodiment, four fin structures 71 are sequentially connected to form a matrix structure. That is, the four fin structures 71 are sequentially connected around the center to form a rectangular structure. During installation, one fin structure 71 is hoisted at a time. First, two adjacent fin structures 71 are hoisted and placed on the same side of the water receiving tray assembly 6. That is, these two fin structures 71 form a fin heat exchanger assembly 7. Then, a partition assembly 8 is installed on the water receiving tray assembly 6. Together with the partition assembly 8 and the two adjacent fin structures 71, a heat exchange air cavity is formed. Then, another two fin structures 71 are hoisted. This arrangement forms a heat pump with four fin structures 71, providing two heat exchange air cavities and improving operating efficiency. Of course, the above description is not restrictive. In some alternative embodiments, only one, two, or more fin structures 71 can be provided.

[0074] It should be noted that the upper connection process also includes: installing a sealing plate 10 at the connection between two adjacent fin structures 71. The installation of the sealing plate 10 can ensure the sealing of the heat exchange air cavity formed by the fin structure 71.

[0075] It should be noted that, during the connection process of the upper portion, a sealing plate 15 is installed at the connection between two adjacent fin structures 71. The provision of the sealing plate 15 ensures the sealing of the heat exchange air cavity formed by the fin structure 71.

[0076] It should be noted that during the upper connection process, an extension plate 21 is installed at the end of the crossbeam structure 2 along the extension direction of the column 1. This extension plate 21 is provided with mounting holes 22, and the extension plate 21 is connected to the column 1 through these mounting holes 22. In this solution, by increasing the contact area between the crossbeam structure 2 and the column 1, the overall stability and torsional resistance of the structure are enhanced. This design effectively distributes and absorbs loads from different directions, ensuring structural stability and effectively reducing the original phenomenon of concentrated stress.

[0077] It should be noted that, during the connection process of the upper part, there are at least two first reinforcing ribs 3; multiple first reinforcing ribs 3 are distributed on both sides of the beam structure 2; the first reinforcing rib 3 includes a first fitting surface 31 and a second fitting surface 32, the first fitting surface 31 is suitable for fitting with the inner bending surface of the column 1; the second fitting surface 32 is suitable for fitting with the upper surface or lower surface of the beam structure 2. In this solution, by adding the first reinforcing rib 3 and fitting the first reinforcing rib 3 tightly with the column 1 and the beam structure 2, the overall stability and torsion resistance of the structure can be enhanced. This design can effectively disperse and withstand loads from different directions, ensure the stability of the structure, and effectively improve the original concentrated stress phenomenon. The force-bearing area is increased, avoiding stress concentration that causes deformation of the column 1 or breakage of the beam, so that the hoisted heat pump system leaves the frame-specific tooling vehicle and moves to the assembly station, where the column 1 serves as a load-bearing member to bear the load.

[0078] This embodiment improves the above-mentioned installation method by dividing the heat pump assembly into an upper part and a lower part. When installing the upper part, the fin heat exchanger assembly 7 is first installed on the water receiving tray assembly 6, and then the column 1 is installed on the water receiving tray assembly 6, thereby solving the problem of the fin heat exchanger assembly 7 being scratched by the column 1 when installing.

[0079] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
