[0003] The existing train wheel body quenching process usually relies on the traditional quenching pool. However, when the traditional quenching pool is used for the quenching process of the train wheel body, due to the non-flowing quenching liquid in the pool, the water temperature is uneven, which leads to a slow cooling speed and uneven cooling of the wheel body, affecting the hardenability of the wheel body.

Detailed Embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-5, A quenching pool for processing train wheel bodies, comprising a pool body 1 and a material placing turntable 3 located inside the pool body 1. On both sides of the upper surface of the pool body 1, mounting grooves 11 are symmetrically opened. Inside the mounting grooves 11, hydraulic cylinders 12 are installed. Inside the pool body 1, there is also a base frame 2. On the surface of the base frame 2, irregular communication grooves 22 are opened. In the middle position of the lower surface of the base frame 2, a submersible motor 23 is installed. The material placing turntable 3 is rotatably connected to the upper surface of the base frame 2. On the outer surface of the material placing turntable 3, tooth blocks 32 are fixedly installed. At the outer edge of the lower surface of the base frame 2, a main stirring rod 4 is rotatably connected. The upper end of the main stirring rod 4 penetrates through the base frame 2 and is fixedly connected with a small gear 41. On the outer surface of the main stirring rod 4, a number of stirring shafts 42 are fixedly installed. When in use, first drive the hydraulic cylinder 12 to make the material placing turntable 3 rise out of the inside of the pool body 1. As Figure 1 shown, at this time, the heat-treated train wheel body can be placed on the upper surface of the material placing turntable 3 through a hoisting tool, and then drive the hydraulic cylinder 12 to drive the material placing turntable 3 and the train wheel body to descend into the inside of the pool body 1. As Figure 5 shown, to cool the wheel body. When cooling the wheel body, the submersible motor 23 can be driven. The submersible motor 23 is a prior art and has a certain waterproof structure and high-temperature resistant structure, which will not be elaborated. For the convenience of understanding, it is not shown in the figure. The submersible motor 23 drives the material placing turntable 3 to rotate, so that the train wheel body on its surface is in a continuous rotation state, thus realizing the uniform cooling of the train wheel body.
[0023] Furthermore, the output end of the hydraulic cylinder 12 extends out of the mounting groove 11. The output end of the hydraulic cylinder 12 is fixedly connected with a connecting rod 21. The lower end of the connecting rod 21 is fixedly connected with the side surface of the base frame 2. When in use, by driving the hydraulic cylinder 12, the hydraulic cylinder 12 can drive the base frame 2 to rise or fall through the connecting rod 21, and then drive the material placing turntable 3 and the train wheel body located on the surface of the material placing turntable 3 to rise or fall.
[0024] Furthermore, the output end of the submersible motor 23 penetrates through the base frame 2 and is in transmission connection with the material placing turntable 3. The tooth blocks 32 are meshed with the small gear 41. On the surface of the material placing turntable 3, a number of water passing holes 31 are evenly opened. When in use, by arranging a number of water passing holes 31 and communication grooves 22, the quenching liquid can flow, thus ensuring the uniformity of the cooling of the train wheel body.
[0025] Furthermore, the material placing turntable 3 is in transmission connection with the main stirring rod 4 through the tooth blocks 32 and the small gear 41. Six main stirring rods 4 are provided and are annularly distributed at the outer edge of the lower surface of the base frame 2. When in use, when the material placing turntable 3 rotates, it will also drive the six small gears 41 meshed with it to rotate synchronously through the tooth blocks 32. The rotation of the small gear 41 will drive the main stirring rod 4 to rotate, and the main stirring rod 4 will drive the stirring shaft 42 to rotate, so as to continuously stir the quenching liquid inside the pool body 1, thus ensuring the fluidity of the quenching liquid.
[0026] Working principle: When using a quenching pool for processing train wheel bodies of the present utility model, the driving hydraulic cylinder 12 drives the material placing turntable 3 to rise out of the inner part of the pool body 1 through the connecting rod 21 and the base frame 2. Then, the heat-treated train wheel body is placed on the upper surface of the material placing turntable 3 through a hoisting tool. Next, the hydraulic cylinder 12 is driven again to drive the material placing turntable 3 and the train wheel body to descend into the inner part of the pool body 1, and then the cooling work can be carried out. During the cooling process of the wheel body, the submersible motor 23 drives the material placing turntable 3 to rotate, so that the train wheel body is in a continuously rotating state, thereby realizing the uniform cooling of the train wheel body. To further ensure the uniformity of cooling, a number of water passing holes 31 are evenly opened on the surface of the material placing turntable 3, and irregular communication grooves 22 are opened on the surface of the base frame 2. Through the water passing holes 31 and the communication grooves 22, the quenching liquid can circulate. When the material placing turntable 3 rotates, it will also drive six small gears 41 meshed with it to rotate synchronously through the tooth blocks 32. The rotation of the small gears 41 will drive the stirring main rod 4 to rotate, and the stirring main rod 4 will drive the stirring shaft 42 to rotate, continuously stirring the quenching liquid inside the pool body 1 to make the quenching liquid flow continuously to ensure the uniformity of the water temperature. Through the above working principle, this quenching pool can realize the effective cooling and uniform quenching of the train wheel body, and improve the quality and service life of the train wheel body.
