Description

Technical Field

[0001] This utility model relates to the field of transformer installation technology, and in particular to a self-balancing power transformer mounting bracket. Background Technology

[0002] In modern power systems, power transformers, as key equipment for power transmission and distribution, are widely used in power plants, substations, and various industrial and civil applications. Their stable operation is crucial for ensuring the reliability and security of power supply. Throughout the transformer's lifecycle, the installation process is fundamental to ensuring its subsequent stable operation. The installation bracket is an indispensable auxiliary device during transformer installation, bearing the important responsibility of supporting and securing the transformer. Its performance directly affects the installation quality and operational stability of the transformer.

[0003] Currently, traditional power transformer mounting brackets present numerous problems in practical applications. Firstly, regarding structural stability, most brackets employ simple frame structures lacking effective adjustment and reinforcement mechanisms. During transportation, vibrations caused by road bumps, or during daily operation due to transformer vibrations, make it difficult for the bracket to ensure the transformer remains in a stable position, easily leading to transformer displacement. Over time, this can cause internal components to loosen, affecting the transformer's performance and lifespan. Secondly, in terms of maintenance convenience, traditional brackets are typically designed to be relatively fixed. When transformer inspection and maintenance are required, it is difficult for personnel to flexibly adjust the transformer's position. This not only increases the difficulty of maintenance operations but may also prolong maintenance time due to inconvenience, thereby affecting the normal power supply of the power system and increasing unnecessary economic losses. Furthermore, traditional brackets are poorly adaptable to transformers of different specifications, often requiring custom-made brackets for different transformer sizes, leading to increased costs and wasted resources.

[0004] In response to this technical problem, this application proposes a self-balancing power transformer mounting bracket. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a self-balancing power transformer mounting bracket. This bracket increases the structural stability of the transformer during installation and facilitates maintenance operations, avoids increased adjustment time and labor costs during installation, improves installation efficiency, enhances the convenience and safety of maintenance work, and fixes the transformer's position during lifting, preventing displacement caused by transportation vibrations, daily operation vibrations, or external impacts, thereby increasing structural stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A self-balancing power transformer mounting bracket includes a mounting frame, with slide rods fixedly connected to both ends of the mounting frame, slide rod rotatably connected to the middle of the mounting frame, a fixed frame fixedly connected to the top of the mounting frame, a motor installed inside the fixed frame, a fixed plate fixedly connected to the rear of the fixed frame, a transformer support plate threaded to the outer wall of slide rod 2, a limit block connected to the bottom of the transformer support plate via an adjusting assembly, and multiple sliding grooves formed on the top of the transformer support plate, with sliding components installed inside the sliding grooves.

[0008] Furthermore, the adjustment assembly includes a connecting frame one that is fixedly connected to the front end of the bottom side of the transformer support plate, a connecting rod that is rotatably connected inside the connecting frame one, and a connecting frame two that is fixedly connected to the front side of the limiting block one.

[0009] Furthermore, the rear end of the connecting rod is rotatably connected inside the second connecting frame, and the first connecting frame and the second connecting frame are connected through the connecting rod.

[0010] Furthermore, the sliding assembly includes two limiting strips fixedly connected to the inside of the sliding groove, and a slider is slidably connected to the adjacent side of the two limiting strips. Limiting grooves are opened on both the front and rear sides of the slider, and the outer wall of the limiting strip is slidably connected to the inner wall of the limiting groove.

[0011] Furthermore, a clamping plate is fixedly connected to the top side of the slider, and anti-slip pads are provided on the adjacent sides of the two clamping plates, and springs are provided on the bottom side of the clamping plates.

[0012] Furthermore, one end of the spring is connected to the inner wall of the groove, and the other end is connected to the adjacent side of the two sliders.

[0013] Furthermore, the drive end of the motor is connected to the top side of the slide bar II.

[0014] Furthermore, two limiting blocks are fixedly connected to the rear end of the bottom side of the transformer support plate, and the rear ends of the two limiting blocks are slidably connected to the outer wall of the slide rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by fixing the transformer support plate to the position of the sliding limit block on the outer wall of the slide rod, the structural stability during the installation and lifting of the transformer is increased, and maintenance operations are facilitated. This avoids the increase in adjustment time and labor costs during the installation process, improves installation efficiency, and enhances the convenience and safety of maintenance work.

[0017] 2. In this utility model, the elastic potential energy generated by the deformation of the springs inside the sliding groove of the clamping plate assists in clamping the transformer, thereby fixing the position of the transformer during lifting and avoiding displacement of the transformer due to factors such as transportation vibration, vibration generated during daily operation, or external impact, thus increasing structural stability.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1This utility model provides an embodiment of a self-balancing power transformer mounting bracket, comprising a mounting frame 1, with sliding rods 5 fixedly connected to both ends of the mounting frame 1, and sliding rod 6 rotatably connected to the middle of the mounting frame 1. A fixing frame 3 is fixedly connected to the top of the mounting frame 1, and a motor 4 is installed inside the fixing frame 3. A fixing plate 2 is fixedly connected to the rear of the fixing frame 3. A transformer support plate 7 is threadedly connected to the outer wall of sliding rod 6. A limit block 11 is connected to the bottom of the transformer support plate 7 via a connecting rod 9. Multiple sliding grooves 13 are formed on the top of the transformer support plate 7, and sliders 14 are installed inside the sliding grooves 13. The rear end of the connecting rod 9 is rotatably connected to the inside of a connecting frame 2 10. The connecting frame 1 8 and the connecting frame 2 10 are connected via the connecting rod 9. A clamping plate 17 is fixedly connected to the top of the slider 14. Anti-slip pads 18 are provided on the adjacent sides of the two clamping plates 17, and springs 19 are provided on the bottom of the clamping plates 17. One end of the spring 19 is connected to the inner wall of the sliding groove 13, and the other end is connected to the adjacent sides of the two sliders 14. The drive end of motor 4 is connected to the top side of slide bar 6. Two limit blocks 12 are fixedly connected to the rear end of the bottom side of transformer support plate 7, and the rear ends of the two limit blocks 12 are slidably connected to the outer wall of slide bar 5.

[0025] Specifically, when the operator begins operation, the two clamping plates 17 on the top of the transformer support plate 7 are first pulled apart to both sides. Slide grooves 13 are provided at both ends of the top of the transformer support plate 7, providing space for the movement of the clamping plates 17. Limiting strips 15 set within the slide grooves 13 engage with limiting grooves 16 on the bottom slider 14 of the transformer support plate 7, thereby restricting the movement of the clamping plates 17. Anti-slip pads 18 on the top of opposite sides of the two clamping plates 17 cooperate to effectively prevent the transformer from shaking during clamping. When either the transformer support plate 7 or the limiting block 11 is fixed, the connecting rod 9 connecting the limiting block 11 to the bottom front end of the transformer support plate 7 forms a triangular stable structure, greatly enhancing the stability when lifting the transformer.

[0026] Reference Figure 2 A connecting frame 1 8 is fixedly connected to the front end of the bottom side of the transformer support plate 7. A connecting rod 9 is rotatably connected inside the connecting frame 1 8. A connecting frame 2 10 is fixedly connected to the front side of the limiting block 1 11.

[0027] Specifically, the transformer support plate 7 is threadedly connected to the outer wall of the slide bar 2 6, and is also connected to the limiting block 11. Therefore, the transformer support plate 7 and the limiting block 11 will move linearly in the vertical direction. Locks are provided at the connection between the transformer support plate 7 and the slide bar 2 6, as well as on both sides of the limiting block 11. When any of these locks is engaged, the placement height of the transformer support plate 7 can be adjusted.

[0028] Reference Figure 3The slide groove 13 has two fixedly connected limit strips 15 inside. A slider 14 is slidably connected to the side of the two limit strips 15 that are close to each other. Limit grooves 16 are opened on both the front and rear sides of the slider 14. The outer wall of the limit strip 15 is slidably connected to the inner wall of the limit groove 16.

[0029] Specifically, after the two clamping plates 17 are pulled apart, the transformer can be placed between them. After the transformer is placed, the clamping plates 17 are released. At this time, the limiting strips 15 connected to the bottom of opposite sides of the two clamping plates 17 deform due to the previous stretching, storing elastic potential energy. Under the action of elastic potential energy, the two clamping plates 17 tightly clamp the transformer.

[0030] Working principle: The operator first pulls the two clamping plates 17 on the top side of the transformer support plate 7 apart to both sides. The sliding grooves 13 at both ends of the top side of the transformer support plate 7 provide space for the movement of the clamping plates 17. The limiting strips 15 set inside the sliding grooves 13 engage with the limiting grooves 16 on the sliders 14 connected to the bottom side of the transformer support plate 7, limiting the movement of the clamping plates 17. After the two clamping plates 17 are pulled apart, the transformer can be placed between the two clamping plates 17. At this time, the two clamping plates 17 are released. The limiting strips 15 connected to the bottom ends of the two clamping plates 17 on the adjacent side generate elastic potential energy under the action of deformation. Under the action of elastic potential energy, the two clamping plates 17 clamp the transformer. The top end of the two clamping plates 17 on the adjacent side is set with The anti-slip pads 18 work together to prevent shaking when clamping the transformer. After the transformer is placed, the motor 4 is started, and the slide rod 6 connected to the drive end of the motor 4 rotates accordingly. At this time, the transformer support plate 7, which is threaded to the outer wall of the slide rod 6, and the limiting block 11 move in a straight line in the vertical direction. The connection between the transformer support plate 7 and the slide rod 6 and both sides of the limiting block 11 are provided with latches. When any of the latches is fixed, the placement height of the transformer support plate 7 can be adjusted. When either the transformer support plate 7 or the limiting block 11 is fixed, the connecting rod 9 connected to the bottom front end of the limiting block 11 and the transformer support plate 7 can form a triangular stable structure, which increases the stability of lifting the transformer.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
