Description

Technical Field

[0001] This utility model relates to the field of tunnel electromechanical equipment technology, specifically to a base for a tunnel DC lighting dimming cabinet. Background Technology

[0002] In existing highway tunnel lighting, DC power supply offers advantages such as safety and energy saving. Furthermore, it allows for intelligent dimming of tunnel lighting based on real-time changes in traffic flow, thereby achieving energy conservation, cost reduction, and efficiency improvement. Therefore, DC lighting dimming systems are increasingly widely used in highway tunnel lighting power supply. The control cabinets for DC lighting dimming systems are typically located in substations within tunnels or in outdoor substations. They are usually designed as outdoor models, with the support base of the outdoor system cabinet often employing a foot-support structure, typically with four to eight support feet depending on the cabinet's weight and size.

[0003] Cabinet base with support foot structure: (1) During manufacturing, the support height of each support foot must be consistent. Therefore, tooling fixtures must be used during welding to ensure the consistency of the overall dimensions. The entire manufacturing process is time-consuming and labor-intensive, resulting in high production costs. (2) During transportation, due to the complex outdoor environment, there is a risk that the support feet may be easily knocked off and lose their support function. (3) During fixed installation, if the ground is uneven, multiple points need to be raised and leveled due to the use of multi-point support, making the installation process time-consuming and labor-intensive. (4) During use, the multi-point support structure of the support feet makes the overall stability of the base greatly affected by the dimensional accuracy of the support feet.

[0004] Chinese utility model application No. 201620257198.6 discloses a cabinet base, including a pair of first frames arranged opposite each other and a pair of second frames connected between the first frames and arranged opposite each other. Each first frame includes a first frame body, edging formed by bending from both ends of the first frame body, and a first mounting surface formed by bending from the edging away from the first frame body. Each second frame includes a second frame body and a second mounting surface formed by bending from both ends of the second frame body, matching the first mounting surface. After the first and second frames are assembled using the first and second mounting surfaces, the first and second mounting surfaces are located inside the cabinet base, resulting in simple and aesthetically pleasing assembly. However, during installation, the cabinet base is laborious due to the limited working space for the mounting screws; furthermore, since the first and second frames are fixed together by screws to form a basic frame, there is a possibility of screw loosening and a decrease in the stability of the cabinet base over time.

[0020] 2. The tolerances for the external dimensions and installation dimensions of batch parts are small. The positioning holes can ensure the relative position and overall forming dimensions of the parts during welding, eliminating the need for tooling fixtures to achieve positioning and forming during welding.

[0021] 3. When the base is formed as a whole, only a minimum of four short welds are required, and a maximum of eight short welds are required, which reduces the welding time; the welding work space is large, and the operation is labor-saving; at the same time, the weld is strong, which reduces the rate at which the stability of the base decreases over time; after the welding is completed, the welding processing marks are not obvious, and the appearance is simple.

[0022] 4. After the base is formed as a whole, during the transportation process, on the one hand, it can avoid the hidden danger of the support feet of the cabinet base with traditional support foot structure being bent. On the other hand, the reserved slots make it easy to use a forklift to move the base and the cabinet as a whole.

[0023] 6. After the base is formed as a whole, the installation process eliminates the need for leveling multiple support feet individually, as is the case with traditional cabinet bases that have support feet. The installation foundation can be set up in advance, making the installation process simple and labor-saving. Attached Figure Description

[0034] To better understand this utility model, the following detailed description is provided in conjunction with specific embodiments.

[0035] Example 1

[0036] like Figures 1 to 5As shown, a base 10 for a DC lighting dimming cabinet in a tunnel includes a first frame 1 and a second frame 2. The first frame 1 is integrally formed and includes a first sub-component 11, a second sub-component 12, and a third sub-component 13. The second end of the first sub-component 11 is connected to the first end of the second sub-component 12, and the second end of the second sub-component 12 is connected to the first end of the third sub-component 13. The first sub-component 11 is perpendicular to the second sub-component 12 and parallel to the third sub-component 13 and of equal length. The second frame 2 is of equal length to the second sub-component 12, and its two ends are welded to the first end of the first sub-component 11 and the second end of the third sub-component 13, respectively.

[0037] like Figures 1 to 3 As shown, the second sub-component 12 and the second frame 2 both have horizontal edges that bend outward by 90° on both their upper and lower sides; the first sub-component 11 and the third sub-component 13 both have horizontal edges that bend inward by 90° on both their upper and lower sides. The upper horizontal edges of the first sub-component 11, the second sub-component 12, the third sub-component 13, and the second frame 2 are on the same plane, and the lower horizontal edges are on the same plane.

[0038] It should be noted that the direction of the length extension of the first sub-component, the second sub-component, the third sub-component, and the second frame is the horizontal direction, and the direction of the width extension is the vertical direction. The length value is greater than the width value. The upper and lower sides refer to the upper and lower sides along the vertical direction. Outward refers to the outer side facing the area enclosed by the first frame and the second frame, and inward refers to the inner side facing the area enclosed by the first frame and the second frame.

[0039] like Figures 1 to 3 As shown, the first end of the first sub-component 11 and the second end of the third sub-component 13 both have vertical edges that bend inward by 90°. These vertical edges are located between the horizontal edges of their respective sub-components, and their width is not greater than the width of the horizontal edges of their respective sub-components. Specifically, the vertical edge of the first end of the first sub-component 11 is located between the upper and lower horizontal edges of the first sub-component 11, and its width is not greater than the width of the upper and lower horizontal edges of the first sub-component 11; similarly, the vertical edge of the second end of the third sub-component 13 is located between the upper and lower horizontal edges of the third sub-component 13, and its width is not greater than the width of the upper and lower horizontal edges of the third sub-component 13. A first positioning hole 18 is provided on each vertical edge, and second positioning holes 21 are provided at both ends of the second frame 2 at positions corresponding to the first positioning holes 18.

[0040] In this embodiment, it is preferred that, as Figures 1 to 4As shown, two first positioning holes 18 are vertically arranged on the vertical edge of the first sub-component 11, and two first positioning holes 18 are also vertically arranged on the vertical edge of the third sub-component 13. Correspondingly, two second positioning holes 21 are vertically arranged at each end of the second frame 2, and the positions of the second positioning holes 21 correspond to the positions of the first positioning holes. It should be noted that the number and arrangement of the first positioning holes 18 and the second positioning holes 21 can be adjusted as needed. The number and arrangement described above are only illustrative examples and not limitations.

[0041] It should be further explained that the widths of the horizontal edges on the upper and lower sides of the first sub-component 11, the second sub-component 12, the third sub-component 13, and the second frame 2 can be adjusted as needed. For example, the widths of the horizontal edges on both sides can be set to be the same; or the widths of the upper edges can be the same, and the widths of the lower edges can be the same but different from the widths of the upper edges; or the widths of the horizontal edges on both sides of the second frame 2 can be different from the widths of the horizontal edges on both sides of the first frame 1, etc. No specific limitations are made in this application. In this embodiment, it is further preferred that the widths of the horizontal edges on both sides of the first sub-component 11, the second sub-component 12, the third sub-component 13, and the second frame 2 are all the same.

[0042] like Figures 1 to 5 As shown, the base 10 of the tunnel DC lighting dimming cabinet also includes an integrally formed vertical support 3. The vertical support 3 includes a first vertical surface 31 and a second vertical surface 32. A vertical edge of the first vertical surface 31 is connected to a vertical edge of the second vertical surface 32, and the first vertical surface 31 and the second vertical surface 32 are perpendicular to each other. The width of the first vertical surface 31 is not greater than the width of the horizontal edge of the second sub-component 12 and the horizontal edge of the second frame 2, and the height is not greater than the distance between the upper and lower horizontal edges of the second sub-component 12, nor greater than the distance between the upper and lower horizontal edges of the second frame 2. A third positioning hole 33 is provided on the second vertical surface 32, and a fourth positioning hole 17 corresponding to the third positioning hole 33 is provided on the second frame 2 and the second sub-component 12. Preferably, in this embodiment, two third positioning holes 17 are vertically arranged on each second vertical surface 32, and two fourth positioning holes 17 are also vertically arranged on the second frame 2 and the second sub-component 12.

[0043] In this embodiment, it is further preferred that two vertical support members 3 are provided, and their second vertical surfaces 32 are welded to the outer surfaces of the second frame 2 and the second sub-component 12, respectively. It should be noted that the number of vertical support members 3 can be adjusted as needed, such as providing four, where the second vertical surfaces 32 of two are welded to the outer surfaces of the second frame 2, and the second vertical surfaces 32 of the other two are welded to the outer surfaces of the second sub-component 12. This application does not impose any limitation. It should be further noted that as the number of vertical support members 3 is adjusted, the number and position of the fourth positioning holes 17 corresponding to the third positioning holes 33 on the second frame 2 and the second sub-component 12 also need to be adjusted accordingly.

[0044] like Figures 1 to 5 As shown, two horizontally arranged slots 16 are provided on the vertical surface between the upper and lower horizontal edges of the second sub-component 12 and the second frame 2, and the positions of the slots 16 on the second sub-component 12 and the second frame 2 correspond to each other.

[0045] like Figures 1 to 4 As shown, the first sub-component 11 and the third sub-component 13 have first mounting holes 14 at both ends of their upper horizontal edges. The second sub-component 12 and the second frame 2 have second mounting holes 15 at both ends of their lower horizontal edges.

[0046] It should be noted that the first frame 1, the second frame 2, and the vertical support 3 can all be manufactured by using a CNC punching and bending machine to precisely punch and bend the sheet metal material, ensuring the forming accuracy of each part, and with less processing time and lower production cost.

[0047] When assembling the base 10 for the tunnel DC lighting dimming cabinet, the following method can be used.

[0048] First, the first frame 1 and the second frame 2 are positioned, and the contact points of the first frame 1 and the second frame 2 are welded. Specifically, positioning elements (such as pins, screws, bolts, etc.) are used to pass through the first positioning hole 18 on the first sub-component 11 and the second positioning hole 21 at one end of the second frame 2; positioning elements (such as pins, screws, bolts, etc.) are used to pass through the first positioning hole 18 on the third sub-component 13 and the second positioning hole 21 at the other end of the second frame 2; during welding, the weld can be located on the inner or outer side of the area enclosed by the first frame 1 and the second frame 2, or on both the inner and outer sides; in this embodiment, the weld is located on the inner side of the area enclosed by the first frame 1 and the second frame 2.

[0049] Then, the vertical support 3, the second sub-component 12, and the second frame 2 are positioned and welded. Specifically, positioning elements (such as pins, screws, bolts, etc.) are used to pass through the third positioning hole 33 on one vertical support 3 and the fourth positioning hole 17 on the second sub-component 12; positioning elements (such as pins, screws, bolts, etc.) are used to pass through the third positioning hole 33 on another vertical support 3 and the fourth positioning hole 17 on the second frame 2; during welding, the weld can be set on one or both sides of the length direction of the second vertical surface 32 of the vertical support 3; in this embodiment, the weld is set on the side of the second vertical surface 32 of the vertical support 3 that is away from the first vertical surface 31.

[0050] It should be noted that when assembling the base 10, all parts can be positioned first and then welded together. During welding, appropriate welding equipment and processes should be selected. Strict quality control should be maintained during welding to ensure strong, uniform welds without defects such as incomplete welds or missed welds. After the base 10 is assembled, it can undergo anti-corrosion treatment, such as spraying rust-preventive paint or outdoor corrosion-resistant coatings, to improve its corrosion resistance.

[0051] When installing the base 10 for the tunnel DC lighting dimming cabinet, the following method can be used.

[0052] First, such as Figure 6 As shown, the tunnel DC lighting dimming cabinet 40 is mounted on the base 10 using bolts, nuts, and the first mounting hole 14;

[0053] Then, as Figure 7 As shown, the forklift claw 50 is passed through the slot 16 to transport the assembled cabinet 40 and base 10 to the installation position.

[0054] Finally, as Figure 8 As shown, the assembled cabinet 40 and base 10 are placed on the leveled mounting base 60 using a forklift, and then fixed to the mounting base through the second mounting hole 15 and anchor bolts.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the foregoing embodiments have described this utility model in detail, those skilled in the art should understand that modifications can be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein, and these substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this utility model.
