However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] See also Figure 1-4The utility model provides a technical solution: a high-efficiency vertical quenching furnace, including a furnace body 1, the material of the furnace body 1 is a high-temperature resistant alloy, which can withstand high temperature environment and maintain structural stability. The bottom surface of the furnace body 1 is fixedly installed with a support leg 11, which is fixed to the bottom surface of the furnace body 1 by bolt connection. The support leg 11 is arranged in a circumferential shape on the bottom surface of the furnace body 1 to provide a stable support force and ensure the stability of the quenching furnace during operation. The top surface of the furnace body 1 is fixedly installed with a drive motor 2, which is fixed to the furnace body 1 by screws to ensure that it is stable and not easy to vibrate. The output end of the drive motor 2 is installed with a rotating shaft 3, and the rotating shaft 3 is connected to the output end of the drive motor 2 by a coupling to achieve torque transmission. A disc 4 is fixedly installed on the surface of the rotating shaft 3, and a key connection is adopted between the disc 4 and the rotating shaft 3 to ensure that the two rotate synchronously. A heating tube 5 is fixedly installed at the bottom end of the rotating shaft 3, and the heating tube 5 is fixed to the bottom end of the rotating shaft 3 by welding to ensure that it is stable and can effectively transfer heat to the steel pipe. A rotating rod 6 is provided through the top surface of the disk 4, and the rotating rod 6 is rotatably connected to the disk 4 through a bearing to realize the free rotation of the rotating rod 6 on the disk 4. A planetary gear 7 is fixedly mounted on one end of the rotating rod 6, and an interference fit is adopted between the two to ensure that the planetary gear 7 can rotate synchronously with the rotating rod 6.

[0025] See also Figure 2-3 , a storage rod 8 is fixedly installed on the other end of the rotating rod 6. The storage rod 8 and the rotating rod 6 are connected by threads and fixed by a locking nut to ensure that the connection is firm. There are four groups of storage rods 8, and the four groups of storage rods 8 are arranged in a circular shape on the surface of the disk 4 to achieve uniform heating and quenching of the steel pipe. A nut 9 is sleeved on the surface of the storage rod 8, and an external thread is provided on the surface of the storage rod 8. An internal thread meshing with the external thread is provided on the inner side of the nut 9. The steel pipe can be tightened and loosened by rotating the nut 9. A sun gear 10 is fixedly installed on the inner wall of the furnace body 1. The sun gear 10 is fixed to the inner wall of the furnace body 1 by welding. The sun gear 10 meshes with the planetary gear 7 to achieve the rotational movement of the planetary gear 7.

[0026] Embodiment 2

[0027] See also Figure 2 and Figure 4, a material receiving mechanism is provided on the surface of the furnace body 1, and the material receiving mechanism includes a reserved groove 12, and the reserved groove 12 is opened on the surface of the furnace body 1. A material receiving tray 13 is installed on the inner wall of the reserved groove 12 by sliding fit, so that the material receiving tray 13 can slide in and out smoothly in the reserved groove 12. A mounting plate 14 is fixedly installed on the surface of the material receiving tray 13 by welding or bolting. Such a design makes the mounting plate 14 stable and reliable and able to withstand large external forces. In order to facilitate the operation of the staff, a friction pad 18 is also installed on the top surface of the mounting plate 14 by pasting or bolting. Such a design increases the friction between the mounting plate 14 and the reserved groove 12, thereby firmly fixing the material receiving tray 13. A support column 15 is fixedly installed on the inner wall of the material receiving tray 13 by bolts or welding. The support column 15 not only plays a supporting role, but also plays a buffering role to a certain extent. The top of the support column 15 is fixed with a tray 16 in the same way. The tray 16 is used to catch the fallen steel pipe to prevent the steel pipe from falling directly to the bottom of the receiving tray 13 and causing damage. In order to further enhance the buffering effect, short columns 17 are evenly distributed on the top surface of the tray 16. These short columns 17 are fixed to the tray 16 by bonding or bolting. When the steel pipe falls onto the tray 16, the short column 17 will first contact the steel pipe and absorb the impact force through its own elastic deformation, thereby protecting the steel pipe from damage. It is worth mentioning that the material of the support column 15 and the short column 17 are both made of heat-resistant rubber. This material is not only resistant to high temperatures, but also has good elasticity and buffering properties, and is very suitable for use in high-temperature environments such as quenching furnaces.

[0028] Working principle: the staff can put the steel pipe that needs to be quenched into the placement rod 8, and then screw in the nut 9. At this time, the steel pipe can be clamped by the nut 9. After the main steel pipe is clamped, the steel pipe can be heated by the heating tube 5, so as to quench the steel pipe. At the same time, the disc 4 can be driven to rotate by the motor. During the rotation of the disc 4, the planetary gear 7 can be driven by the sun gear 10. When the planetary gear 7 rotates, it can drive the rotating rod 6 to rotate, and the rotating rod 6 can then drive the placement rod 8 to rotate, and the placement rod 8 then drives the steel pipe to rotate. In this way, the steel pipe can be quenched in all directions. The new type directly heats the steel pipe through the heating tube 5, realizing a fast and uniform heating process. At the same time, the motor drives the rotating mechanism of the disc 4 and the planetary gear 7, so that the steel pipe can be evenly heated during the quenching process, improving the efficiency and effect of quenching, and the rotating rod 6 drives the placement rod 8 and the steel pipe to rotate, ensuring that the steel pipe can be treated in all directions during the quenching process. This rotary quenching method helps to reduce quenching dead angles and makes the performance of the steel pipe more uniform. The staff can pull the mounting plate 14 outward until the mounting plate 14 drives the receiving tray 13 to disengage from the reserved groove 12. At this time, The receiving tray 13 can be removed, and then the material can be loaded through the reserved groove 12. In the process of quenching, if the steel pipe falls due to loose fixation, the provided tray 16 can catch the fallen steel pipe. At this time, the short column 17 can buffer the steel pipe to prevent the steel pipe from being deformed. At the same time, the tray 16 can also move downward to squeeze the support column 15 to deform, which can further buffer the steel pipe and ensure that the steel pipe does not deform. In the utility model, the staff can easily remove the receiving tray 13 by pulling the mounting plate 14 outward, and then load the steel pipe through the reserved groove. 12 is used for loading, which simplifies the operation process of loading and unloading and improves work efficiency. During the quenching process, if the steel pipe falls due to loose fixation, the tray 16 can quickly catch the steel pipe and perform preliminary buffering through the short column 17, which effectively reduces the impact force on the steel pipe and reduces the risk of damage or deformation of the steel pipe due to falling. At the same time, the tray 16 can not only catch the fallen steel pipe, but also further buffer the impact force by squeezing the support column 15 by moving downward. This double buffering mechanism provides more comprehensive protection for the steel pipe and ensures the integrity and quality of the steel pipe during the quenching process.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
