[0025] The first embodiment of the present utility model is as follows:

[0026] A lifting device for quenching a supporting wheel includes a base and a main machine 1 and a lifting device arranged on the upper part of the base. A quenching assembly is provided at the front of the main machine 1, and the lifting device is located below the quenching assembly. A control device, a water tank, and power equipment are provided inside the main machine 1. Loading, work station operation and unloading are achieved through the lifting device, and quenching is completed through the quenching assembly.

[0027] The lifting device includes a conveyor belt 9, which is provided with a plurality of first chain plates 15 and second chain plates 16 connected end to end. In this embodiment, an end-to-end connection method of two first chain plates 15 and two second chain plates 16 is adopted. The first chain plate 15 is a plate-shaped structure, and a half-carrying seat 10 is provided in the middle of the second chain plate 16. The half-carrying seats 10 on adjacent second chain plates 16 are combined to form a carrier 10 for placing supporting wheels. A through hole 17 is provided in the middle of the carrier 10. The upper diameter of the carrier 10 is smaller than the diameter of the lower part, and the outer side surface of the upper part of the carrier 10 is an arc surface. The shape of the carrier 10 is adapted to the supporting wheels. When in use, the supporting wheels can be placed on the carrier 10, which can play a positioning role.

[0028] A cylinder 11 is provided below the conveyor belt 9. A bearing 13 is provided at the upper end of the piston rod 12 of the cylinder 11 and is connected to a loading head 14 through the bearing 13. The loading head 14 is located directly below the through hole 17 and can pass through the through hole 17. When the loading base 10 moves to directly above the loading head 14, the cylinder 11 drives the loading head 14 upward through the piston rod 12, so that the supporting wheel can be lifted, and the shape of the loading head 14 is adapted to the shape inside the supporting wheel, which plays a role in enhancing stability; the piston rod 12 and the loading head 14 are connected by a bearing 13 to ensure that the loading head 14 and the piston rod 12 can rotate relative to each other.

[0029] The carrier 10 stops when it moves to just above the carrier head 14. At this time, the carrier 10 at the front end moves to just below the carrier 10, ensuring that the piston rod 12 can pass through the through hole 17 of the front end carrier 10 without interference.

[0030] The quenching assembly includes an induction coil 5 fixedly installed on the front of the main machine 1 and an electronic control device and a transformer connected to the induction coil 5 installed inside the main machine 1. The induction coil 5 is located directly above the carrier head 14. When the carrier head 14 moves upward to the top, the supporting roller is located inside the induction coil 5. A machine head 2 is provided at the front of the main machine 1. A drive motor is provided inside the machine head 2. The output shaft 3 of the drive motor is connected to the rotating head 4. When the carrier head 14 moves upward to the top, the upper end of the supporting roller contacts the rotating head 4. At this time, the drive motor is turned on and drives the supporting roller to rotate through the rotating head 4. The electronic control system starts to generate a high-frequency alternating magnetic field through the induction coil 5. The supporting roller will be induced and generate eddy currents, which will cause the workpiece to heat up. The heating by the induction coil 5 has the advantages of fast heating speed, uniform heating, and low energy consumption, thereby completing the heating of the supporting roller surface.

[0031] A water pump is also provided inside the machine head 2. One end of the water pump is connected to a nozzle 18 through a water pipe. The nozzle 18 is set to face the induction coil 5. The other end of the water pump is connected to a water tank. After heating is completed, quenching liquid is sprayed to the supporting wheel through the nozzle 18 to complete quenching.

[0032] The lower part of the conveyor belt machine 9 is connected with a plurality of columns 8 to play a supporting role.

[0033] The end of the conveyor belt 9 close to the cylinder 11 is connected to the slide 6 and the storage bin 7. The conveyor belt 9 and the storage bin 7 are connected through the slide 6. After quenching is completed, the cylinder 11 drives the piston rod 12 to descend, so that the supporting wheel falls back on the loading seat 10. At this time, the conveyor belt 9 continues to work. When the second chain plate 16 moves to the end and turns, the two half loading seats 10 will separate. Since the upper end side surface of the half loading seat 10 is an arc surface and the inner side surface of the supporting wheel is also an inclined surface, the supporting wheel will move upward and separate from the loading seat 10 during the separation process, and then move from the slide 6 to the storage bin 7.

[0034] It should be noted that the terms "first, second and third" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
