Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker entry height adjustment device. Background Art
[0002] Due to the height and hoisting height restrictions of the GIS room, when the circuit breaker of the later expansion project is brought in, since the early equipment has been installed, the circuit breaker needs to be installed in the middle of the equipment interval. The circuit breaker needs to cross the existing interval to be in place, but the circuit breaker is too high and the height of the hook in the room is too low to make the circuit breaker cross the existing interval to be in place.
[0003] The existing circuit breaker needs to be shipped to the site first, and then the driving mechanism of the circuit breaker needs to be removed on site to lower the height before the circuit breaker body can be put in place. This process is time-consuming and labor-intensive, and reduces the installation progress. If the circuit breaker body with the driving mechanism removed can be directly transported to the site, the circuit breaker body can be directly put in place on site, thereby improving the installation progress. Therefore, a device dedicated to fixing the circuit breaker body is needed to facilitate the transportation and installation of the circuit breaker body. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a height adjustment device suitable for transporting and fixing a circuit breaker body, which facilitates the installation of the circuit breaker body and improves the installation progress.
[0005] The utility model is realized by the following technical scheme: a circuit breaker entry height adjustment device, comprising a base frame and a mechanism frame fixed on the base frame, wherein the mechanism frame comprises two middle supports and two side supports arranged along the length direction of the base frame, the two middle supports are opposite, the two side supports are distributed on both sides of the two middle supports, and the tops of the middle supports and the side supports are both bolted to the circuit breaker body.
[0006] This solution supports and fixes the middle part of the circuit breaker body through two middle supports, and further supports and stabilizes the two ends of the circuit breaker body through two side supports. The two middle supports and the two side supports are screwed and fixed to the circuit breaker body, which is convenient for disassembly and assembly. This device fixes the circuit breaker body, facilitates the transportation and installation of the circuit breaker body, and improves the installation progress.
[0007] As an optimization, the bottoms of the middle support and the side support are both fixedly connected with the base frame bolts. This optimization solution facilitates the disassembly, assembly and replacement of the middle support and the side support.
[0008] As an optimization, the middle support includes two vertical beams extending vertically. The upper ends of the two beams are fixedly connected by a first upper top plate, and the lower ends of the two beams are fixedly connected by a first lower bottom plate. A plurality of screw holes are formed in the first upper top plate. In this optimized solution, the weight of the circuit breaker body is transmitted to the chassis through the beams, making the overall structure stable. The two beams are connected by the first upper top plate and the first lower bottom plate to improve the overall structural strength. The first upper top plate is bolted to the circuit breaker body, and the first lower bottom plate is fixedly connected to the chassis, which is convenient for installation.
[0009] As an optimization, the side support includes a bent plate extending vertically. The cross section of the bent plate includes two opposite first vertical sides and a first horizontal side connecting the two first vertical sides. A second upper top plate is fixedly connected to the upper end of the bent plate, and a second lower bottom plate is fixedly connected to the lower end of the bent plate. A plurality of screw holes are formed in the second upper top plate. In this optimized solution, the weight of the circuit breaker body is transmitted to the chassis through the bent plate, improving the support stability for the circuit breaker body. The second upper top plate is bolted to the circuit breaker body, and the second lower bottom plate is fixedly connected to the chassis, which is convenient for installation.
[0010] As an optimization, a reinforcing rib plate is fixedly connected between the bottom of the second upper top plate and the side wall of the bent plate. This optimized solution improves the connection strength between the second upper top plate and the bent plate of the side support.
[0011] As an optimization, the chassis includes two opposite first bottom beams and two second bottom beams located between the two first bottom beams. The two ends of the second bottom beams are fixedly connected to the two first bottom beams. In this optimized solution, the two first bottom beams are fixedly connected by the second bottom beams, improving the overall structural strength of the chassis. The first bottom beams and the second bottom beams extend vertically, making the chassis more stable, thereby ensuring the stability of fixing the circuit breaker body.
[0012] As an optimization, a third lower bottom plate is fixedly connected between the two second bottom beams. This optimized solution further improves the connection strength between the two second bottom beams through the third lower bottom plate, further improving the support stability.
[0013] As an optimization, the distance between the two second bottom beams is adapted to the length of the middle support. This optimized solution enables the two ends of the middle support to be directly lapped and fixed on the two second bottom beams, so that the forces at the two ends of the middle support can be transmitted to the two second bottom beams, avoiding deformation in the middle of the middle support.
[0014] The beneficial effects of the present utility model are as follows: The middle part of the circuit breaker body is supported and fixed by two middle supports, and the two ends of the circuit breaker body are further supported and stabilized by two side supports. The two middle supports, the two side supports and the circuit breaker body are screwed and fixed, which is convenient for disassembly and assembly. This device fixes the circuit breaker body, facilitating the transportation, installation and positioning of the circuit breaker body, and improving the installation progress. The chassis ensures the stability during transportation. The middle supports and the side supports are screwed and fixed to the chassis, facilitating disassembly and replacement of different height mechanism frames, and making it more convenient to use.

The two ends of the second bottom beam 42 are fixedly connected to the two first bottom beams 41, and a third lower bottom plate 43 is fixedly connected between the two second bottom beams 42.
[0026] AsFigure 3 , 4 As shown, in this embodiment, the first bottom beam 41 is a channel steel, and the second bottom beam 42 is an H-shaped steel. The length directions of the first bottom beam and the second bottom beam are perpendicular to each other. The two ends of the second bottom beam 42 are welded and fixed to the side walls of the two first bottom beams 41. The third lower bottom plate is located at the lower ends of the side walls of the two second bottom beams and is welded and fixed to the second bottom beams. Moreover, the distance between the two second bottom beams 42 is adapted to the length of the intermediate support 51. The two ends of the intermediate support 51 are respectively fixedly connected to the two second bottom beams 42 by bolts. The second bottom beam 42 is provided with screw holes 6 for the bolts to pass through. The two side supports 52 are respectively fixedly connected to the two first bottom beams 41 by bolts. The first bottom beam 41 is provided with screw holes 6 for the bolts to pass through.
[0027] As Figure 5 shown, the intermediate support 51 includes two vertically extending upright beams 511. The upper ends of the two upright beams 511 are connected and fixed by a first upper top plate 512, and the lower ends of the two upright beams 511 are connected and fixed by a first lower bottom plate 513. The first upper top plate 512 is provided with a plurality of screw holes 6. In this embodiment, the upright beam 511 is a channel steel, and the open ends of the two channel steels are arranged opposite to each other. The screw holes of the first upper top plate 512 and the bolt holes reserved at the bottom of the circuit breaker body 1 are connected by bolts. The two ends of the first lower bottom plate 513 are also provided with screw holes, and the screw holes of the first lower bottom plate 513 and the screw holes on the two second bottom beams 42 are connected by bolts.
[0028] As Figure 6 shown, the side support 52 includes a bent plate 521 extending vertically. The cross section of the bent plate 521 includes two opposite first vertical sides 5212 and a first horizontal side 5211 connecting the two first vertical sides. The upper end of the bent plate 521 is fixedly connected with a second upper top plate 522, and the lower end of the bent plate 521 is fixedly connected with a second lower bottom plate 523. The second upper top plate 522 is provided with a plurality of screw holes 6. The screw holes of the second upper top plate 522 and the bolt holes reserved at the bottom of the circuit breaker body 1 are connected by bolts.

[0029] Working principle: As Figure 1 shown, the existing circuit breaker includes a circuit breaker body 1. A transmission box 2 is provided at the bottom of the circuit breaker body. A driving mechanism 3 is fixedly provided at the bottom of the transmission box 2. Due to the height and angle of the circuit breaker, it cannot straddle the existing interval for installation, and the circuit breaker needs to be disassembled on site to achieve installation. As Figure 2As shown in the figure, in order to improve the installation progress, before the circuit breaker is shipped, the height is adjusted first. That is, the driving mechanism 3 of the circuit breaker is removed, leaving only the circuit breaker body 1 and the transmission box 2. The circuit breaker body 1 and the transmission box 2 are installed on the mechanism frame 5 of the present utility model. During installation, the transmission box 2 is arranged between two intermediate supports 51. Then, the two side supports 52 and the two intermediate supports 51 are sequentially bolted and fixed to the bottom of the circuit breaker body 1. That is, the fixation of the circuit breaker body 1 is completed, achieving the purpose of reducing the height of the circuit breaker. Thus, after the circuit breaker body enters the site, it can be directly installed without being disassembled on-site, improving the installation progress.
