Abstract

This utility model discloses an adjustable-spacing transformer and rectifier mounting base, specifically relating to the field of transformer and rectifier installation technology. It includes a base crossbeam and two mounting frames located above the base crossbeam. Each mounting frame includes two mounting longitudinal plates and a second mounting transverse plate welded between the two longitudinal plates. After equipment installation, if the spacing between the transformer and rectifier is incorrect, external tools can be used to connect positive and negative lead screws and drive them to rotate. This causes the sliders to move away from each other, and through linkage transmission, the base plate moves downwards into the inner side of the base crossbeam, reducing friction between the mounting frame and the base crossbeam, facilitating fine-tuning. Furthermore, no holes need to be drilled in the base crossbeam before adjustment; drilling is only required after the spacing is adjusted. This simplifies the installation process, improves installation efficiency, avoids damage to the structural strength of the base crossbeam from excessive drilling, and extends the service life of the base.

Description

Technical Field

[0001] This utility model relates to the field of transformer and rectifier installation technology, and in particular to an adjustable-spacing transformer and rectifier mounting base. Background Technology

[0002] Transformers and rectifiers are common devices in power systems, used for voltage conversion and current rectification, respectively. Transformers change AC voltage through electromagnetic induction, while rectifiers convert AC to DC. They are typically installed in separate cabinets or as integrated units, usually mounted on the same mounting base. This design aims to optimize space, save costs, and achieve functional synergy through an integrated layout. To ensure a safe distance between the transformer and rectifier after installation, the mounting bases are usually adjustable in spacing.

[0003] Existing mounting bases for transformers and rectifiers typically consist of a base and two mounting brackets. The two brackets are used to mount the transformer and rectifier. Before being fully secured to the base with bolts, the spacing between the brackets can be adjusted laterally to meet electrical safety distance, heat dissipation, or maintenance requirements. After adjustment, the mounting brackets are fixed to the base with bolts or locking devices to ensure stable equipment operation.

[0004] The inventors have discovered at least the following problems in the prior art:

[0005] Existing adjustable-spacing transformer and rectifier mounting bases require the spacing to be adjusted before equipment installation when adjusting the distance between the two mounting brackets. After installation, since the equipment has already been placed on the mounting brackets, further adjustments are not possible. Adjusting the spacing after the equipment is placed on the mounting brackets due to friction between the mounting brackets and the base, as well as the weight of the equipment, would make it difficult and inconvenient to adjust the spacing after the transformer and rectifier are placed.

[0006] In addition, both mounting brackets are connected to the base by bolts, which means that after each adjustment, holes need to be drilled again for installation and fixation, which is very cumbersome. Moreover, drilling holes in the mounting bracket multiple times will also limit its service life.

[0007] Therefore, this solution provides an adjustable-spacing transformer and rectifier mounting base to address the aforementioned technical problems. Utility Model Content

[0008] The purpose of this utility model is to provide an adjustable spacing transformer and rectifier mounting base to solve the problems of difficulty in fine-tuning the mounting bracket after equipment installation and cumbersome installation after each adjustment in the prior art.

[0009] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0010] An adjustable-spacing transformer and rectifier mounting base includes a base crossbeam and two mounting frames located above the base crossbeam. Each mounting frame includes two mounting longitudinal plates and a second mounting crossbeam welded between the two longitudinal plates. A first mounting crossbeam is also provided on both sides of the second mounting crossbeam. A lifting assembly is mounted on the inner side of the first mounting crossbeam, and a snap-fit ​​assembly is provided on the outer periphery of the first mounting crossbeam. The lifting assembly includes a top plate and a bottom plate located below the top plate. A notch is formed on one side of the bottom plate, and a mating shaft block is fixedly connected to the inner wall of the notch. Positive and negative lead screws are rotatably connected inside the top plate, with both ends of the positive and negative lead screws penetrating the mounting longitudinal plates. The snap-fit ​​assembly includes a sliding plate and a connecting plate rotatably connected to the top of the sliding plate. A snap-fit ​​block is fixedly connected to the side of the sliding plate near the mounting longitudinal plates and the base crossbeam. A snap-fit ​​groove is formed at the snap-fit ​​block location on the base crossbeam.

[0011] Preferably, the top plate has two symmetrical sliders slidably connected below it, and the threads at both ends of the positive and negative lead screws are threadedly connected to the sliders.

[0012] Preferably, each slider is rotatably connected to a connecting rod below it, and the lower end of the connecting rod is rotatably connected to a base plate.

[0013] Preferably, the bottom end of the base plate is provided with moving wheels that are evenly arranged and rotatably connected.

[0014] Preferably, one side of the mounting plate has an insertion groove, the upper end of the sliding plate fits into the insertion groove, one side of the snap-fit ​​block is equipped with a rubber gasket, and one side of the sliding plate has a pair of mounting holes.

[0015] Preferably, the connecting plate has a mating notch at the lower end away from the sliding plate, and the mating notch fits the periphery of the mating shaft block.

[0016] Preferably, there are three horizontally arranged base frames, and each row of base frames is fixedly connected with evenly distributed vertical base frames, and the mounting plate has mounting slots on its upper part.

[0017] The beneficial effects of this utility model are:

[0018] I. This utility model, through the cooperation of the lifting component and the snap-fit ​​component, enables fine-tuning after the transformer and rectifier are installed. Even after the equipment is installed, if the distance between the transformer and rectifier is found to be incorrect, the positive and negative lead screws can still be connected by external tools and driven to rotate, so that the sliders move away from each other and the base plate moves down into the inner side of the base crossbeam through the linkage transmission, thereby reducing the friction between the mounting frame and the base crossbeam and facilitating further fine-tuning.

[0019] Second, this utility model, through the cooperation of the lifting component and the snap-fit ​​component, eliminates the need to drill holes in the base crossbeam before adjustment. Drilling is only required after the spacing is adjusted. This not only makes it easier to install the frame and the base crossbeam, reducing cumbersome steps in the installation process, but also avoids drilling too many holes in the base crossbeam, thereby reducing damage to its structural strength and extending the service life of the base.

[0030] Please refer to the following. Figures 1 to 6As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0032] This utility model provides an adjustable spacing transformer and rectifier mounting base, including a base crossbeam 1 and two mounting frames 3 located above the base crossbeam 1. The mounting frame 3 includes two mounting longitudinal plates 31 and a second mounting transverse plate 33 welded between the two mounting longitudinal plates 31. The second mounting transverse plate 33 is also provided on both sides of the second mounting transverse plate 33. A lifting component 4 is installed on the inner side of the first mounting transverse plate 32, and a snap-fit ​​component 5 is provided on the outer periphery of the first mounting transverse plate 32.

[0033] The lifting assembly 4 includes a top plate 41 and a bottom plate 45 located below the top plate 41. A notch 47 is provided on one side of the bottom plate 45. A docking shaft block 48 is fixedly connected to the inner wall of the notch 47. A positive and negative screw rod 42 is rotatably connected inside the top plate 41. The two ends of the positive and negative screw rod 42 are installed through the longitudinal plate 31.

[0034] The snap-fit ​​assembly 5 includes a sliding plate 51 and a connecting plate 53 rotatably connected to the top of the sliding plate 51. A snap-fit ​​block 55 is fixedly connected to the side of the sliding plate 51 near the mounting longitudinal plate 31 and the base crossbeam 1.

[0035] The base crossbar 1 has a snap-fit ​​groove 11 at the snap-fit ​​block 55;

[0036] The mounting longitudinal plate 31, mounting horizontal plate one 32, and mounting horizontal plate two 33 are all channel steel, and the slots of mounting horizontal plate one 32 and mounting horizontal plate two 33 face downwards and are aligned with the slots of the base cross frame 1. Therefore, when the base plate 45 moves down, it can enter the slot of the base cross frame 1. The sliding plate 51 and the snap-fit ​​block 55 are a whole, and its cross-section is similar to an F shape. The base plate 45 is thicker at the notch slot 47, so as to ensure that the base plate 45 is strong enough to support the mounting frame 3 above and the equipment above the mounting frame 3. In addition, there is a beveled surface at the upper end of the notch slot 47, which can guide the end of the connecting plate 53 during the upward movement, so that the docking notch 54 can accurately dock with the docking shaft block 48.

[0037] In a further embodiment, two symmetrical sliders 43 are slidably connected below the top plate 41, and the threads at both ends of the positive and negative lead screws 42 pass through the sliders 43.

[0038] In this embodiment, the top plate 41 is bolted into the inner groove of the mounting horizontal plate 32, and the bottom surface of the top plate 41 is provided with a sliding groove for the slider 43 to slide; the two ends of the positive and negative lead screws 42 can be welded to the mounting vertical plate 31 to connect external tools.

[0039] In a further embodiment, a connecting rod 44 is rotatably connected to the lower part of each slider 43, and the lower end of the connecting rod 44 is rotatably connected to the base plate 45.

[0040] In this embodiment, when the two sliders 43 move away from each other, the connecting rod 44 will cause the base plate 45 to move down, thereby allowing the base plate 45 to enter the inner groove of the base crossbar 1.

[0041] In a further embodiment, the bottom end of the base plate 45 is provided with uniformly arranged and rotatably connected movable wheels 46.

[0042] In this embodiment, the movable wheel 46 is a rubber wheel, and the base plate 45 has an ear plate at the movable wheel 46 so that the movable wheel 46 can be rotated and connected.

[0043] In a further embodiment, a plug groove 321 is provided on one side of the mounting plate 32, the upper end of the sliding plate 51 fits into the plug groove 321, a rubber gasket 56 is installed on one side of the snap block 55, and a pair of mounting holes 52 are provided on one side of the sliding plate 51.

[0044] In this embodiment, the rubber pad 56 will be squeezed and deformed after entering the snap-fit ​​groove 11, thereby increasing the friction between the rubber pad 56 and the snap-fit ​​groove 11 after initial installation; the mounting hole 52 is used to assist the staff in drilling holes at the corresponding positions of the base crossbeam 1 after determining the adjustment spacing, and then complete the final connection with bolts; the insertion groove 321 is used to facilitate the upper end of the sliding plate 51 to pass through the connecting plate 53.

[0045] In a further embodiment, a docking notch 54 is provided below the end of the connecting plate 53 away from the sliding plate 51, and the docking notch 54 fits the periphery of the docking shaft block 48.

[0046] In this embodiment, the docking notch 54 is similar to a hook and fits into the docking shaft block 48. The docking shaft block 48 is composed of a round rod and an inverted T-shaped block fixed below the round rod, and the two are an integral structure.

[0047] In a further embodiment, there are three horizontal base frames 1 arranged laterally, and each row of horizontal base frames 1 is fixedly connected with evenly distributed vertical base frames 2, and an installation slot 311 is provided above the mounting plate 31.

[0048] In this embodiment, the base horizontal frame 1 and the base vertical frame 2 constitute the mounting base. Both the base horizontal frame 1 and the base vertical frame 2 are H-beams. The outer periphery of the base horizontal frame 1 also has foot plates for fixing to the concrete base with bolts. The mounting slot 311 is used to install a transformer or rectifier with bolts.

[0049] The working principle of this utility model is as follows:

[0050] Before installing the transformer and rectifier, adjust the distance between the two mounting frames 3, and then install the transformer and rectifier above the two mounting frames 3. If the distance between the transformer and rectifier is found to be incorrect, connect one end of the positive and negative lead screw 42 directly through an external tool and drive it to rotate. This will cause the two sliders 43 to move away from each other, and after being transmitted through the connecting rod 44, the base plate 45 will move down into the inner side of the base crossbeam 1, so that the moving wheel 46 contacts the bottom surface of the inner side of the base crossbeam 1, thereby supporting the entire mounting frame 3. At this time, the friction between the mounting frame 3 and the base crossbeam 1 is reduced, so that it is easier to make fine adjustments to the distance after installing the transformer and rectifier.

[0051] After confirming the spacing between the two mounting frames 3, the top of the sliding plate 51 can be inserted into the insertion slot 321. At this time, the connecting plate 53 will be located at the notch 47 of the base plate 45, and the mating notch 54 at the end of the connecting plate 53 will be directly above the mating shaft block 48. Meanwhile, the snap-fit ​​block 55 and the rubber gasket 56 will be on the same horizontal plane as the snap-fit ​​slot 11. Then, the forward and reverse screws 42 are rotated by the tool in the opposite direction, which will cause the base plate 45 to move upward as a whole. When the mating shaft block 48 is snapped into the mating notch 54, as it continues to move upward, the connecting plate 53 will pull the sliding plate. 51. The snap-fit ​​block 55 moves closer to the mounting plate 32 and the base crossbeam 1, thereby allowing the snap-fit ​​block 55 and the rubber gasket 56 to enter the snap-fit ​​groove 11, completing the initial connection between the mounting frame 3 and the base crossbeam 1. Finally, the base crossbeam 1 is drilled through the mounting hole 52 and fixed by bolts. This eliminates the need to drill holes in the base crossbeam 1 before adjustment, and only requires drilling after the spacing is adjusted. This not only makes it easier to install and remove the mounting frame 3 and the base crossbeam 1, thus improving installation efficiency, but also avoids drilling too many holes in the base crossbeam 1, which would reduce its structural strength.

[0052] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
