Description

Technical Field

[0001] The utility model relates to the technical field of transformer installation, in particular to a transformer support device for a box-type substation. Background Technique

[0002] A box-type transformer (usually abbreviated as "box substation") integrates a traditional transformer in a box-type housing, which has the advantages of small volume, light weight, low noise, low loss, and high reliability, and is widely used in residential areas, commercial centers, light stations, airports, factories, mines, enterprises, hospitals, schools and other places.

[0003] At present, some existing box substations need to install transformers of different models in the box according to the installation location and power consumption. When changing the transformer model, there may be a problem that the installation holes of the transformer are different from the reserved installation holes in the box. At this time, an opening tool needs to be used to re-open the installation holes inside the box to install the transformer in the box, which is relatively time-consuming and laborious and relatively inconvenient to use. For this reason, we propose a transformer support device for a box substation to solve or improve the above problems. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a transformer support device for a box substation, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: including a bottom plate, a support block fixed on the top of the bottom plate, a mounting plate inserted into the top of the support block, a second limiting groove opened on the inner surface of the support block, a first limiting groove opened on the inner surface of the support block, a limiting component A arranged inside the mounting plate, and a support component B arranged on one side of the bottom of the mounting plate.

[0006] Furthermore, the limiting component A includes a first connecting column inserted into the mounting plate, a first limiting tooth block fixed at the bottom of the first connecting column, the first limiting tooth block meshed with the second limiting groove, and a first spring sleeved on the surface of the first connecting column.

[0007] Furthermore, the support component B includes a slider slidably installed inside the support block through a chute, a second connecting column inserted into the slider, a second limiting tooth block fixed at the bottom end of the second connecting column, the second limiting tooth block meshed with the first limiting groove, a second spring sleeved on the surface of the second connecting column, and a connecting plate rotatably installed on the surface of the slider through a rotating shaft.

[0008] Furthermore, a bearing column is fixed inside the support block, the bearing column passes through the inside of the mounting plate and is slidably connected with the mounting plate, and two groups of bearing columns are symmetrically fixed inside the support block.

[0009] Furthermore, a concealed handle is provided at the top of the first connecting post. A slot for accommodating the concealed handle is opened at the top of the mounting plate, and mounting holes are opened at the top of the mounting plate.

[0010] Furthermore, one end of the connecting plate is rotatably mounted on the surface of the slider through a rotating shaft, and the other end is rotatably mounted on the bottom of the mounting plate through a rotating shaft.

[0011] Compared with the prior art, the utility model has the following beneficial effects: By providing the mounting plate and the limiting device A, when the transformer model to be installed and replaced causes the mounting hole positions to change, the first connecting post can be pulled to drive the first limiting tooth block to move, releasing the limit on the mounting plate. At this time, the mounting plate can be moved to a position where the top mounting hole position is aligned with the transformer mounting hole position. Releasing the first connecting post can cause the first spring to push the first limiting tooth block to move, so that the first limiting tooth block is re-engaged with the second limiting groove, thereby restricting the position of the mounting plate and making its position relatively fixed, thus completing the adjustment of the mounting hole position without having to re-open mounting holes in the box body, which is relatively time-saving and labor-saving, relatively convenient to use, and reduces the maintenance and replacement time.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1-7 , including a bottom plate 1, a support block 2 fixed to the top of the bottom plate 1. Four groups of support blocks 2 are symmetrically fixed to the top of the bottom plate 1. An installation plate 3 is inserted into the top of the support block 2. The installation plate 3 is slidably connected to the support block 2 and a limiting block is provided on the surface of the installation plate 3. The limiting block can limit the position of the installation plate 3, greatly reducing the amplitude of shaking and tilting of the installation plate 3 during movement and enhancing the stability of the installation plate 3 during movement. Installation holes are opened on the top of the installation plate 3, through which the transformer can be conveniently installed. A bearing column 4 is fixed inside the support block 2. The bearing column 4 passes through the inside of the installation plate 3 and is slidably connected to the installation plate 3. Two groups of bearing columns 4 are symmetrically fixed inside the support block 2. The bearing column 4 can provide auxiliary support for the installation plate 3, sharing part of the pressure on the top of the installation plate 3 and reducing the bearing pressure of the limiting block on the surface of the installation plate 3. At the same time, the bearing column 4 can limit the position of the installation plate 3, greatly reducing the amplitude of shaking and tilting of the installation plate 3 during movement and enhancing the stability of the installation plate 3 during movement. A second limiting groove 6 is opened on the inner surface of the support block 2, a first limiting groove 5 is opened on the inner surface of the support block 2, a limiting component A is arranged inside the installation plate 3, and a support component B is arranged on one side of the bottom of the installation plate 3.

[0022] The internal of the limit component A includes a first connecting column 8 inserted into the mounting plate 3. The top of the first connecting column 8 is provided with a concealed handle. A slot for accommodating the concealed handle is opened at the top of the mounting plate 3. The concealed handle can be accommodated inside the slot provided at the top of the mounting plate 3, thus avoiding affecting the installation of the transformer. By pulling the concealed handle, the fixed first connecting column 8 can be driven to move. A first limit tooth block 7 is fixed to the bottom of the first connecting column 8. The first limit tooth block 7 is meshed and connected with the second limit slot 6. When the first connecting column 8 moves, it will drive the fixed first limit tooth block 7 to move. When the first limit tooth block 7 moves, it will disengage from the meshing connection with the second limit slot 6. A first spring 9 is sleeved on the surface of the first connecting column 8. One end of the first spring 9 contacts the surface of the first limit tooth block 7, and the other end contacts the inner surface of the mounting plate 3. When the first limit tooth block 7 moves, it will squeeze the first spring 9 to cause the first spring 9 to deform and generate elastic potential energy. When there is no external force interference, the first spring 9 will push the first limit tooth block 7 to move so that it is meshed and connected with the second limit slot 6 again. When the first limit tooth block 7 is meshed and connected with the second limit slot 6, it will limit the position of the mounting plate 3 and make it unable to move.

[0023] The support component B internally contains a slider 10 slidably installed inside the support block 2 through a chute. The slider 10 can slide inside the support block 2. A limiting block is provided on the surface of the slider 10, which can limit the position of the slider 10 to prevent the slider 10 from detaching from the inside of the support block 2. A second connecting column 13 inserted into the slider 10, a second limiting tooth block 11 fixed to the bottom end of the second connecting column 13. The second limiting tooth block 11 is meshed with the first limiting groove 5. When the second connecting column 13 moves, it will drive the fixed second limiting tooth block 11 to move. When the second limiting tooth block 11 moves, it will disengage from the meshing connection with the first limiting groove 5. A second spring 14 sleeved on the surface of the second connecting column 13. One end of the second spring 14 contacts the surface of the second limiting tooth block 11, and the other end contacts the inner surface of the slider 10. When the second limiting tooth block 11 moves, it will squeeze the second spring 14 to cause the second spring 14 to deform and generate elastic potential energy. When there is no external interference, the second spring 14 will push the second limiting tooth block 11 to move so that the second limiting tooth block 11 re-engages with the first limiting groove 5. When the second limiting tooth block 11 is meshed with the first limiting groove 5, the second limiting tooth block 11 will limit the position of the slider 10, making it unable to move and its position relatively fixed. A connecting plate 12 rotatably installed on the surface of the slider 10 through a rotating shaft. One end of the connecting plate 12 is rotatably installed on the surface of the slider 10 through a rotating shaft, and the other end is rotatably installed at the bottom of the mounting plate 3. When the mounting plate 3 needs to move, pulling the second connecting column 13 can make the second connecting column 13 drive the fixed second limiting tooth block 11 to move, so that the second limiting tooth block 11 disengages from the meshing connection with the first limiting groove 5, thereby making the second limiting tooth block 11 no longer limit the position of the slider 10. At this time, the mounting plate 3 can be moved. The mounting plate 3 will drive the rotatably installed connecting plate 12 to move. When the connecting plate 12 moves, it will drive the rotatably connected slider 10 to move. After the mounting plate 3 moves to a suitable position, releasing the second connecting column 13 enables the second spring 14 to push the second limiting tooth block 11 to move, so that the second limiting tooth block 11 can re-engage with the first limiting groove 5 and limit the position of the slider 10. Thus, the slider 10 and the connecting plate 12 can assist in supporting the mounting plate 3, enabling the connecting plate 12 and the slider 10 to bear a part of the pressure on one side of the top of the mounting plate 3, improving the load-bearing capacity of the mounting plate 3.

[0024] Working principle: When the installation hole position changes due to the replacement of the installed transformer model, pulling the first connecting column 8 can drive the first limiting tooth block 7 to move, so that the first limiting tooth block 7 disengages from the meshing connection with the second limiting groove 6, and thus the first limiting tooth block 7 no longer restricts the position of the mounting plate 3. At this time, the mounting plate 3 can be moved to a suitable position until the mounting plate 3 moves to a position where the top mounting hole position is aligned with the transformer mounting hole position. Releasing the first connecting column 8 can enable the first spring 9 to push the first limiting tooth block 7 to move, so that the first limiting tooth block 7 meshes with the second limiting groove 6 again, and the first limiting tooth block 7 restricts the position of the mounting plate 3 again through the second limiting groove 6, making its position relatively fixed, thereby completing the adjustment of the mounting hole position. There is no need to re-drill mounting holes in the box body, which is relatively time-saving and labor-saving and relatively convenient to use.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
