[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figures 1-4 The present invention includes a base 1, a hydraulic mechanism 2 fixedly connected to the top of the base 1, a top plate 3 fixedly connected to the top of the hydraulic mechanism 2, a connecting frame 4 fixedly connected to the bottom of the top plate 3, a first clamping plate 5 fixedly connected to the bottom of the connecting frame 4, a first recess 7 provided on both the surface and the back of the first clamping plate 5, and a rotating shaft 9 rotatably inserted into both sides of the inner wall of the first recess 7. The rotating shaft 9 enables the support rod 8 to rotate, thereby facilitating the insertion of the fixing frame at the bottom of the transformer into the first clamping plate 5 and the second clamping plate 6. A support rod 8 is fixedly connected between the two rotating shafts 9, a pad 10 is fixedly connected to the bottom of the two support rods 8, and a second clamping plate 6 is sleeved between the bottom of the two support rods 8. A second recess 11 is provided on both the surface and the back of the second clamping plate 6, and the bottom of the two support rods 8 is inserted into the two second recesses 11.

[0020] Meanwhile, the pad 10 is cylindrical in shape, and both the pad 10 and the support rod 8 are made of stainless steel. The advantage of this design is that it makes the entire device more stable.

[0021] In addition, the connecting frame 4 is divided into four diagonal rods, four fixed rods and four connecting rods. The four diagonal rods are fixed to the four corners at the bottom of the top plate 3, and the four connecting rods are fixed to the bottom of the four diagonal rods. The four connecting rods are connected and fixed in sequence by the four fixed rods. The advantage of this arrangement is that the entire device can be easily fitted onto the circumferential surface of the transformer, thereby facilitating the limiting and fixing of the fixed frame at the bottom of the transformer.

[0022] Furthermore, there are two bases 1, and each base 1 has two pulleys at its bottom. The two pulleys are located on the front and rear sides of the bottom of the base 1, respectively. The four pulleys make it easier to move the entire device.

[0023] Furthermore, there are four sets of first clamping plates 5, with each set located at the bottom of one of the four fixing rods. Each set of first clamping plates 5 is correspondingly provided with a set of four sets of second clamping plates 6. The arrangement of the four sets of first clamping plates 5 and second clamping plates 6 makes it easier to fix the fixing frame at the bottom of the transformer, thereby making the fixing of the fixing frame at the bottom of the transformer more stable and improving the stability of the entire device.

[0024] It should also be noted that the tops of the four second clamping plates 6 are equipped with anti-slip pads and protective pads. The advantage of this design is that when moving the transformer, it prevents the fixing frame from sliding against the second clamping plates 6, thereby preventing the transformer from slipping and being damaged.

[0025] Working principle: When the transformer needs to be moved, firstly, the connecting frame 4 is sleeved on the transformer. Then, the hydraulic mechanism 2 is activated to drive the top plate 3 to slide downwards, which in turn drives the second clamping plate 6 to slide upwards. Since the support rod 8 is rotatably connected to the rotating shaft 9 in the first recess 7, the support rod 8 can be rotated. When the support rod 8 drives the pad 10 to disengage from the second clamping plate 6 at the second recess 11, the fixing frame at the bottom of the transformer can be inserted between the first clamping plate 5 and the second clamping plate 6. Then, the support rod 8 is rotated in the opposite direction so that it is inserted into the second recess 11, thereby limiting and fixing the fixing frame at the bottom of the transformer. Then, the hydraulic mechanism 2 drives the top plate 3 to slide upwards, which in turn drives the first clamping plate 5 and the second clamping plate 6 to slide upwards through the connecting frame 4, thus driving the transformer to slide upwards. Finally, the transformer can be moved by the pulleys.

[0026] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
