[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. With the rapid development of my country's national economy, the demand for electricity is also increasing. As the main equipment in the power transmission and transformation system, the transformer has also developed rapidly.

[0003] The transformer is installed between two poles through a mounting frame, and the width of the existing mounting frame is fixed and inconvenient to adjust. In order to install transformers of different widths on the upper end of the mounting frame, it is necessary to weld a widening frame on the upper end of the mounting frame according to the width of the transformer before installing the transformer. This will increase the installation and adjustment time of the mounting frame and delay the subsequent installation of the transformer. Therefore, it is necessary to design a transformer mounting frame. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a transformer mounting frame, comprising a fixed shell, two support frames distributed on the left and right are slidably connected inside the fixed shell, a first fastening ring is fixedly connected inside the two support frames, a second fastening ring is provided at one end of the two first fastening rings away from each other, the first fastening ring and the second fastening ring are connected by bolts, two support frames are fixedly connected at the front and rear ends of the fixed shell, support rods are slidably connected inside the multiple support frames, sliding holes are provided on the lower end surfaces of the multiple support frames, sliding blocks are slidably connected inside the multiple sliding holes, the sliding blocks are fixedly installed on the bottom end of the support rods, a position adjustment component is installed at the bottom end of the fixed shell, and the position adjustment component is connected to the sliding block and provides power for the sliding block position adjustment operation.

[0006] Furthermore, the position adjustment assembly includes a connecting rod, a motor, a bearing seat, a bidirectional threaded rod and a movable plate. The lower end of the fixed shell is fixedly connected to the motor and the bearing seat. The inside of the bearing seat is rotatably connected to the bidirectional threaded rod. The output shaft end of the motor is fixedly connected to the bidirectional threaded rod.

A position adjustment component is installed at the bottom end of the fixed shell 1, and the position adjustment component is connected to the sliding block 15, and provides power for the position adjustment operation of the sliding block 15. When working, the utility model facilitates the expansion of the width of the fixed shell 1 through the cooperation of the support frame 6, the support rod 7 and the position adjustment component, so as to facilitate the use of the overall equipment to install and support transformers of different widths.

[0022] Further, the position adjustment assembly includes a connecting rod 12, a motor 19, a bearing seat 16, a bidirectional threaded rod 20 and a moving plate 14, the lower end of the fixed shell 1 is fixedly connected with the motor 19 and the bearing seat 16, the inner part of the bearing seat 16 is rotatably connected with the bidirectional threaded rod 20, the output shaft end of the motor 19 is fixedly connected with the bidirectional threaded rod 20, the circumferential surface of the bidirectional threaded rod 20 is threadedly connected with two moving plates 14 distributed left and right, the front and rear sides of the upper ends of the two moving plates 14 are both rotatably connected with the connecting rod 12, and the multiple connecting rods 12 are respectively rotatably connected with the multiple sliding blocks 15. When working, the motor 19 can drive the bidirectional threaded rod 20 to rotate, and at this time, the two moving plates 14 can simultaneously move in a direction away from each other, and then, under the cooperation of the multiple connecting rods 12 and the multiple sliding blocks 15, the support rod 7 is simultaneously driven to move along the support frame 6, so that the support rod 7 and the support frame 6 are relatively displaced, and the total width of the overall device changes, so that it is convenient to use the overall device to support and fix transformers of different widths.

[0023] Furthermore, the bottom end of the fixed shell 1 is fixedly connected to two sliding rods 17 symmetrically distributed front and back through a fixed block, and both sliding rods 17 penetrate the movable plate 14, and both movable plates 14 are slidably connected to the two sliding rods 17.
