[0022] 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.

[0023] Please see Figure 1-5 The present invention provides the following technical solution:

[0024] A transformer core installation mechanism includes a base plate 1 and a core body 4. A support roller 2 is provided on the top of the base plate 1. A first electric telescopic rod 3 is fixedly connected to both sides of the top of the base plate 1. A top support mechanism 5 is provided on both sides of the top of the base plate 1. A pulling mechanism 6 is provided on the top of the top support mechanism 5. The top support mechanism 5 includes a second electric telescopic rod 501, a sliding frame 502, a top plate 503, and a plurality of rubber columns 504. The surface of the telescopic end of the second electric telescopic rod 501 is fixedly connected to the surface of the top plate 503. The side of the rubber column 504 near the top plate 503 is fixedly connected to the surface of the top plate 503. The bottom of the sliding frame 502 is fixedly connected to the top of the top plate 503. The surface of the rubber column 504 is in close contact with the inner wall of the core body 4.

[0025] In this embodiment: the support roller 2 is rotatably connected to the rotating frame 11, allowing the iron core body 4 to easily move from the top of the base plate 1 to the bottom of the top plate 503. Then, the extension ends of the two first electric telescopic rods 3 are simultaneously controlled to retract, driving the lifting plate 8 and the top plate 503 to move down into the iron core body 4. Then, the extension ends of the two second electric telescopic rods 501 are simultaneously controlled to extend. Since they are fixed on the support plate 10, they will drive the top plate 503 to move, so that the rubber column 504 is in close contact with the inner wall of the iron core body 4 to achieve initial fixation. Afterwards, the extension ends of the two first electric telescopic rods 3 are simultaneously controlled to extend, and the lifting plate 8 drives the sliding rod 603 through the connecting block 601 and the pulling plate 602. The transformer core 4 is lifted by the friction between the rubber column 504 and the core body 4. The slide rod 603 supports and protects the second electric telescopic rod 501. After the core body 4 is lifted, the transformer housing is moved to the top of the support roller 2 and pushed below the core body 4. Then, the telescopic ends of the two first electric telescopic rods 3 are retracted simultaneously to complete the installation of the core body 4. The operation is simple and efficient, with low labor requirements. It solves the problem that some large and heavy transformer cores are inconvenient to move or lift into the transformer housing during installation, requiring hoisting equipment and a lot of manpower to assist in the operation, which affects the installation efficiency of transformer cores.

[0026] Specifically, such as Figure 2 As shown, the traction mechanism 6 includes two connecting blocks 601, two traction plates 602 and a slide rod 603. The slide frame 502 is slidably sleeved on the surface of the slide rod 603. The bottom of the traction plate 602 is fixedly connected to the top of the slide rod 603. The side of the traction plate 602 near the connecting block 601 is fixedly connected to the surface of the connecting block 601.

[0027] Specifically, such as Figure 2 As shown, a support plate 10 is fixedly connected to the bottom of the slide rod 603, and the side of the second electric telescopic rod 501 near the support plate 10 is fixedly connected to the support plate 10.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, a lifting plate 8 is fixedly connected between the top of the telescopic ends of the two first electric telescopic rods 3, and the top of the connecting block 601 is fixedly connected to the bottom of the lifting plate 8.

[0029] In this embodiment: the pulling mechanism 6, through the cooperation of the connecting block 601, the pulling plate 602 and the slide rod 603, combined with the sliding frame 502 on the slide rod 603, realizes the stable movement of the top plate 503. The support plate 10 provides stable support for the second electric telescopic rod 501, ensuring reliable top support action. The lifting plate 8 connects the first electric telescopic rod 3 and the connecting block 601 to form a complete force transmission path, ensuring the stability of the iron core body 4 during the rising process and improving installation accuracy.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, a reinforcing frame 7 is fixedly connected to the top of the lifting plate 8. The reinforcing frame 7, the lifting plate 8, the connecting block 601, the sliding rod 603, the sliding frame 502, the support plate 10 and the top plate 503 are all made of high-strength steel.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, a rotating frame 11 is fixedly connected to the top of the base plate 1. The number of rotating frames 11 and support rollers 2 are both several and evenly distributed on the top of the base plate 1. The support rollers 2 are rotatably connected inside the rotating frame 11.

[0032] Specifically, such as Figure 1 As shown, positioning bolt holes 9 are provided at the four corners of the top of the base plate 1.

[0033] In this embodiment: the high-strength steel reinforcing frame 7, lifting plate 8, connecting block 601, sliding rod 603, sliding frame 502, support plate 10 and top plate 503 enhance the overall structural strength and load-bearing capacity, and extend service life. The cooperation between the rotating frame 11 and the support roller 2 greatly reduces the movement resistance of the iron core body 4 and the subsequent transformer housing, making it easier to align. The positioning bolt holes 9 can fix the base plate 1, preventing the base plate 1 from shifting during installation, thus improving the overall safety and efficiency of the installation operation of the iron core body 4.

[0034] Working principle: The support roller 2 is rotatably connected to the inside of the rotating frame 11, which allows the iron core body 4 to easily move from the top of the base plate 1 to the bottom of the top plate 503, greatly reducing the difficulty of moving the iron core body 4. First electric telescopic rods 3 are fixedly connected to both sides of the top of the base plate 1. A lifting plate 8 is fixedly connected between the top of the telescopic ends of the two first electric telescopic rods 3. The top of the connecting block 601 is fixedly connected to the top of the lifting plate 8. When the iron core body 4 moves into position, the telescopic ends of the two first electric telescopic rods 3 are simultaneously controlled to retract, which will cause the lifting plate 8 and the top plate 503 to descend together, thereby moving the top plate 503 into the interior of the iron core body 4. Then, the telescopic ends of the two second electric telescopic rods 501 are simultaneously controlled to extend. Due to the second electric... The telescopic rod 501 is fixed to the support plate 10. Its extension and retraction will drive the top plate 503 to move. The sliding frame 502 is slidably sleeved on the surface of the sliding rod 603, so that the top plate 503 moves stably, thereby bringing the rubber column 504 closer to the iron core body 4. Finally, the surface of the rubber column 504 is in close contact with the inner wall of the iron core body 4, achieving initial fixation of the iron core body 4. The top of the top support mechanism 5 is provided with a traction mechanism 6. After the rubber column 504 is in close contact with the inner wall of the iron core body 4, the extension and retraction ends of the two first electric telescopic rods 3 are extended at the same time. At this time, the lifting plate 8 rises, which drives the sliding rod 603 to rise through the connecting block 601 and the traction plate 602. Through the friction between the rubber column 504 and the iron core body 4, the iron core body 4 can be lifted upward. At this point, the slide bar 603 bears the weight of the iron core body 4 and will not affect the second electric telescopic rod 501. The top of the lifting plate 8 is fixedly connected to the reinforcing frame 7. The reinforcing frame 7, lifting plate 8, connecting block 601, slide bar 603, slide frame 502, support plate 10 and clamping plate are all made of high-strength steel, which ensures the structural strength and stability of the entire mechanism when bearing the weight of the iron core body 4, and can safely and reliably complete the lifting action. The four corners of the top of the base plate 1 are provided with positioning bolt holes 9, which can be used to fix the base plate 1 in a suitable position to ensure the stability of the base plate 1 during installation. After the iron core body 4 is lifted, the transformer shell is moved to the top of the support roller 2. The shell can be easily moved to the iron core body 4 by the rotation of the support roller 2. The bottom of the transformer is then controlled, and the two first electric telescopic rods 3 are simultaneously retracted. This allows for convenient and quick installation of the core body 4 inside the transformer housing. The operation is simple, improves the installation efficiency of the core body 4, and requires less labor. It solves the problem that some large and heavy transformer cores are inconvenient to move or lift into the transformer housing during installation, requiring hoisting equipment and a large number of workers, which affects the installation efficiency of the transformer core. It should be noted that the core body 4, the transformer housing, the first electric telescopic rod 3, and the second electric telescopic rod 501 are all existing and published mature technologies, and the first electric telescopic rod 3 and the second electric telescopic rod 501 are powered by an external power supply.Furthermore, the movement of the two first electric telescopic rods 3 and the two second electric telescopic rods 501 is simultaneously controlled by an external synchronous controller; the basic mechanism of this control will not be elaborated upon here.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
