[0002] The distribution cabinet is an indispensable part of the power system, which is mainly used to distribute electric energy to various electrical equipment and control and monitor the power supply. The structure of the distribution cabinet mainly includes a main body, a door body is provided at the front end of the main body, and in order to facilitate the installation of components such as circuit breakers, longitudinal beams and cross beams are installed inside the main body. The specific structure of the cross beam is as shown in the Chinese patent announcement number CN204597224U, which discloses a new type of distribution cabinet cross beam. The cross beam body includes an upper beam plate 11 and a plug bottom plate 21, and the plug sealing plate 22 is connected to the two by welding. Due to the special structure of the cross beam body, it is usually necessary to manually weld the plug sealing plate. During welding, the sealing plate is spot welded by hand for preliminary fixation, and then welded firmly along the weld. This traditional method is difficult to hold the sealing plate by hand, and the sealing plate is easy to move, which makes the connection quality between the sealing plate and the cross beam body poor. On the other hand, the welding speed is slow and the labor cost is high. Utility Model Content

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Example

[0029] As mentioned in the background technology, in the existing distribution cabinet, beams are installed as supporting parts for various electronic components. The existing beams include a main body and a sealing plate 2. During processing, the sealing plate 2 needs to be sealed at the end of the main body by welding. Due to the special structure at both ends of the main body, welding needs to be done manually. However, the inventor found that when welding, the sealing plate 2 and the main body need to be held by hand. On the one hand, the sealing plate 2 is prone to displacement, resulting in poor welding quality. On the other hand, the welding speed of the hand-held sealing plate 2 is slow. Therefore, the inventor designed an auxiliary frame for beam welding using existing components, which will be explained in detail below with reference to the drawings.

[0030] This embodiment provides a distribution cabinet crossbeam welding frame, see Figure 1, it is possible to limit the crossbeam body 1 and the sealing plate 2 and assemble the two. The crossbeam body 1 is consistent with the crossbeam structure in the patent document mentioned in the background technology. The two sealing plates 2 are fixed to the crossbeam body 1 by welding. In this solution, the welding frame includes a bottom plate 3 set to be rectangular. The length of the bottom plate 3 should be greater than the length of most beams to improve the scope of application. Two supporting plates 4 are fixed to the two longer edge positions of the upper end surface of the bottom plate 3, that is, a U-shaped opening is formed between the two support plates 4 and the bottom plate 3.

[0031] In this solution, multiple first support frames 5 and second support frames 6 are installed at intervals on the bottom plate 3 on the opposite side of the two support plates 4, which can support the beam body 1, and the opposite sides of the first support frame 5 and the second support frame 6 are both vertical planes. When supporting the beam body 1, they can be offset against the side surfaces of the beam body 1. The offset of the two planes improves stability, and the first support frame 5 is fixed to the bottom plate 3 by bolts 11. In order to be able to adjust the distance between adjacent first support frames 5, multiple threaded holes 12 for fixing the first support frames 5 are opened on the bottom plate 3 along the arrangement direction of the first support frames 5. The first support frame 5 is fixed to different positions by combining the bolts 11 with different threaded holes 12, which can be specifically determined according to the length of beams of a certain batch of the same model.

[0032] One of the fixing methods of the second support frame 6 is to fix it to the bottom plate 3 by means of bolts 11, that is, the distance between the second support frame 6 and the first support frame 5 is fixed, such as Figure 1 and Figure 2 As shown, a crossbeam body 1 can be placed on the inner side of the first support frame 5 and the second support frame 6 for limiting. However, in this solution, the second support frame 6 is also designed to be movable, that is, the distance between it and the first support frame 5 can be adjusted. Specifically, this is achieved by designing a driving component to drive all the second support frames 6 to move.

[0033] Specifically, combined Figure 3 and Figure 4The second support frame 6 is slidably connected to the bottom plate 3, and the upper ends of the multiple second support frames 6 are commonly connected to the moving bar 13, and in order to facilitate the connection between the moving bar 13 and the second support frame 6, the upper end surface of the second support frame 6 is a horizontal plane, and is connected to the moving bar 13 through a connecting column 20, and the driving assembly is connected to the moving bar 13, which can drive it to move. Specifically, the driving assembly includes a screw 16 spanning the two support plates 4, that is, the screw 16 is perpendicular to the length direction of the support plate 4, and the screw 16 is rotatably connected to the support plate 4 through the bracket 17, the screw 16 is threadedly connected to a threaded barrel 18, and the threaded barrel 18 is fixed to the moving bar 13, and the end of the screw 16 close to the second support frame 6 is connected to a handwheel 19, and the handwheel 19 is rotated to drive the screw 16 to rotate, and then the threaded barrel 18 is driven to move along the screw 16 through thread engagement, and then the second support frame 6 is driven to move along the moving bar 13 toward or away from the first support frame 5.

[0034] It should be noted that when using the second support frame 6 of the above design, the beam body 1 is first placed horizontally on the base plate 3 at the bottom of the screw 16, and is against the first support frame 5. Then, the screw 16 is controlled to rotate to drive the second support frame 6 to move to against the other side of the beam body 1 and clamp it.

[0035] Moreover, the second support frame 6 is connected to a slider 14 , and a sliding groove 15 for the slider 14 to slide is opened on the bottom plate 3 along the width direction. When the second support frame 6 slides, the slider 14 is driven to slide along the sliding groove 15 .

[0036] The 3rd support frame 8 is fixed to the bottom plate 3 and the side plate 7 by the third support frame 8 respectively by bolts 11.
