[0025] A hydraulic push rod 21 is fixedly connected to one side of the auxiliary part 12, a cross bar 20 is fixedly connected to the outer ring surface of the hydraulic push rod 21, and one end of the hydraulic push rod 21 is fixedly connected to the connecting part. There are two groups of support rods 19, each group of support rods 19 has two support rods 19, the two support rods 19 are hinged, and one end of one of the support rods 19 is hinged to the auxiliary part 12, a plurality of through holes are opened on the outer ring surface of the sleeve rod 7, the bottom of the sleeve rod 7 passes through the support plate 8, and a rectangular auxiliary hole is opened on the top of the support plate 8.

[0026] Specifically, the exhaust pipe can exhaust the excess air inside the drying box 2. An electric control valve is installed on the exhaust pipe. The support plate 8 can support the bottom of the threaded rod 14. The threaded rod 14 can be rotated to drive the scraper 15 to move up and down under the action of the thread, so that the scraper 15 moves up and down along the sleeve rod 7, driving the winding sleeved on the sleeve rod 7 to move, so that the winding is separated from the sleeve rod 7. The guide member 18 and the auxiliary member 12 can support the two ends of the support rod 19 respectively, so as to improve the stability of the hydraulic push rod 21 during installation and use. The cross bar 20 is used to connect the two hydraulic push rods 21, and the hydraulic push rod 21 can be adjusted. The installation of the rod 21 is further strengthened. The hydraulic push rod 21 can drive one side of the connector to realize the lifting and lowering adjustment of the support plate 8, so that the sleeve rod 7 and the winding can extend out of or enter the drying box 2. There is no need to manually reach into the drying box 2 to take out the winding, which is more convenient to use.

The through holes opened on the outer annular surface of the sleeve rod 7 allow air to pass through the sleeve rod 7 from the bottom of the support plate 8 and contact the inner wall of the winding, thereby increasing the contact area with the winding and improving the drying effect of the winding.

[0027] As an optimization solution, Figure 1-Figure 5 As shown, an electric control box 3 is fixedly connected to one side of the drying box 2, and the electric control box 3 is electrically connected to a temperature sensor 4, which is inserted through the top plate 1, and a pressure relief valve 5 is fixedly connected to one side of the top plate 1, and a fan 2 17 is fixedly connected to the bottom of the inner cavity of the drying box 2, and a drying plate 2 16 is fixedly connected to the top of the fan 2 17, and a plurality of exhaust holes are opened on the top of the drying plate 2 16, and a guide plate 13 is fixedly connected to one side of the drying plate 2 16, and the bottom of the guide plate 13 is fixedly connected to the drying box 2, and an extension plate 11 is slidably connected to one side of the guide plate 13, and the top of the extension plate 11 is fixedly connected to the support plate 8, and a fan 16 is fixedly connected to one side of the drying box 2, and a fan 16 is fixedly connected to one side of the fan 16, and a drying plate 9 is fixedly connected to one side of the fan 16 through a connecting pipe, and an exhaust hole is opened on one side of the drying plate 9, and a heating tube 10 is fixedly connected to one side of the inner wall of the drying plate 9.

[0028] Specifically, the drying box 2 can be used to support one side of the electric control box 3, which is convenient for the installation and use of the electric control box 3. The signal sent by the temperature sensor 4 can be received through the electric control box 3, and the signal can be processed by the PLC controller inside the electric control box 3, and the processed signal can be transmitted to the control terminal. The drying box 2 can be used to support the bottom of the fan 17. The drying plate 16 can send the air blown out by the fan 17 upward, so that the air passes through the rectangular auxiliary holes on the support plate 8, thereby accelerating the air flow around the winding and improving the drying effect on the winding. The guide plate 13 is slidably connected to the extension plate 11. The guide plate 13 can be used to guide the sliding of the extension plate 11 when it is raised or lowered, thereby improving the stability of the extension plate 11 and the support plate 8 when they are raised or lowered, and limiting the downward movement range of the support plate 8 and the extension plate 11. The heating tube 10 inside the drying plate 9 can be used to heat the air entering the drying plate 9, thereby adjusting the temperature of the air discharged from the drying plate 9. The pressure relief valve 5 can assist in the discharge of gas inside the drying box 2, thereby improving the safety of the drying box 2 when in use.

[0029] Working principle: First, open the top plate 1, and put the transformer winding that needs to be dried on the sleeve rod 7, then use the hydraulic push rod 21 to drive the connecting piece to move, and the connecting piece moves along the auxiliary piece 12 to change the inclination angle of the two support rods 19, thereby driving the support plate 8 to move down, and adjust the use height of the support plate 8 to make the winding go deep into the drying box 2, and then use the fan 16 and the fan 2 17 to blow air into the drying plate 1 9 and the drying plate 2 16 respectively. The drying plate 1 9 and the fan 2 17 are both equipped with heating tubes 10. The use of the heating tube 10 in the drying plate 2 16 can be controlled by the electric control box 3, and the winding can be heated and dried by hot air. The temperature sensor 4 can be used to monitor the temperature inside the drying box 2. The two fans 17 can adjust the temperature inside the drying box 2 to avoid excessive temperature. Excess air can be discharged through the exhaust pipe. When the air pressure inside the drying box 2 is higher than the preset value, the pressure relief valve 5 opens to accelerate the exhaust, thereby maintaining the air pressure inside the drying box 2 basically constant. After the winding drying process is completed, the hydraulic push rod 21 is used to drive the connecting piece to move in the reverse direction, change the height of the support plate 8, and remove the top plate 1. At this time, the sleeve rod 7 and the winding leak out, and then the threaded rod 14 is rotated, and the scraper 15 moves up along the sleeve rod 7 to push the winding to move on the outer annular surface of the sleeve rod 7, thereby assisting the separation of the winding and the sleeve rod 7, and the winding can be quickly taken out.
