[0019] Example:

[0020] like Figure 1-Figure 2 As shown, a cleaning device for heat treatment of railway spring bars comprises an ultrasonic cleaning box 1, a rotating frame 2 with an open top is provided inside the ultrasonic cleaning box 1, a rotating motor 21 driving the rotating frame 2 to rotate is connected to the bottom of the rotating frame 2, a moving frame 3 connected to the rotating frame 2 for sliding up and down is provided inside the rotating frame 2, a plurality of layers of isolation nets 31 are provided inside the moving frame 3, a universal rotating seat 32 is rotatably connected to the top of the moving frame 3, a mounting plate 4 is provided on one side of the ultrasonic cleaning box 1, a drying chamber 41 is provided on the mounting plate 4 above the ultrasonic cleaning box 1, and a lifting assembly 5 connected to the universal rotating seat 32 is provided above the drying chamber 41. The rotating frame 2 and the moving frame 3 are both hollow structures.

[0021] The spring bars are placed according to their size, with large spring bars on the bottom layer of the moving frame 3 and small spring bars on the upper isolation net 31. The spring bars are placed in an isolated manner to avoid accumulation of spring bars, ensure comprehensive cleaning, and avoid collision and damage of spring bars during cleaning. The moving frame 3 is quickly placed into the rotating frame 2 by the lifting assembly 5, and the moving frame 3 is quickly taken out from the rotating frame 2 and moved to the drying chamber 41, so as to facilitate the cleaning and drying of the spring bars without manual operation and improve work efficiency. During cleaning, the spring bars are immersed in the cleaning liquid, the rotating motor 21 drives the rotating frame 2 to rotate, and the spring bars are driven by the rotating frame 2 to rotate synchronously in the moving frame 3 for centrifugal cleaning. At the same time, the ultrasonic wave of the ultrasonic cleaning box 1 performs ultrasonic cleaning of the spring bars by strong ultrasonic oscillation. Multiple cleaning methods are carried out simultaneously to improve the cleaning effect and make the cleaning more thorough.

[0022] The drying chamber 41 is composed of three-side enclosures 42 and a mounting plate 4. The enclosures 42 and the mounting plate 4 are both provided with air inlets 43, and the air inlet 43 is connected to an air inlet fan 45 and a heater through an air inlet pipe 44. The air inlet fan 45 introduces hot air into the drying chamber 41 to dry the elastic bars in the moving frame 3 by hot blowing.

[0023] A slide groove 22 is provided on the inner side of the rotating frame 2, and a slider 23 is provided on the outer side of the moving frame 3 to be slidably connected to the slide groove 22. The slide groove 22 is U-shaped or dovetail-shaped, and the moving frame 3 stably falls into the rotating frame 2 by the cooperation of the slide groove 22 and the slider 23, so as to avoid shaking and causing collision of the spring bars in the moving frame 3, and when the rotating frame 2 rotates, it will drive the moving frame 3 to rotate together, so as to realize the rotating cleaning of the spring bars in the moving frame 3.

[0024] The movable frame 3 is provided with a position sensor 33, which is electrically connected to the lifting assembly 5 via the controller. The position sensor 33 accurately measures the position of the movable frame 3, and when it is detected that the movable frame 3 moves downward into the rotating frame 2, the movement is stopped and the cleaning process is performed; when it is detected that the movable frame 3 moves upward into the drying chamber 41, the movement is stopped and the drying process is performed.

[0025] The lifting assembly 5 includes a winding shaft 51, which is rotatably mounted on the mounting plate 4 through a bracket 52. A lifting motor 53 is provided at one end of the winding shaft 51 to drive the winding shaft 51 to rotate. A lifting rope 54 connected to the universal rotating seat 32 is wound on the winding shaft 51. When the lifting motor 53 drives the winding shaft 51 to rotate in the forward direction, the lifting rope 54 is wound on the winding shaft 51, so that the moving frame 3 rises; when the lifting motor 53 drives the winding shaft 51 to rotate in the reverse direction, the winding shaft 51 puts down the lifting rope 54, so that the moving frame 3 falls.

[0026] The inner wall of the ultrasonic cleaning box 1 is provided with a plurality of flushing nozzles 11, and the nozzles of the plurality of flushing nozzles 11 are all oriented at different angles toward the moving frame 3. The flushing nozzles 11 include an upper nozzle, a middle nozzle, and a lower nozzle. The upper nozzle sprays obliquely from top to bottom to the moving frame 3, the lower nozzle sprays obliquely from top to bottom to the moving frame 3, and the middle nozzle sprays horizontally to the moving frame 3. The plurality of flushing nozzles 11 are used to perform flushing from a plurality of different angles, thereby reducing blind spots in cleaning.

[0027] Working process:

[0028] Before cleaning, the spring bars are placed according to their size, with large spring bars on the bottom layer of the moving frame 3 and small spring bars on the upper isolation net 31. The winding shaft 51 is then driven by the lifting motor 53 to rotate in the opposite direction to move the moving frame 3 downward into the rotating frame 2. After the position sensor 33 detects that the moving frame 3 has moved into position in the rotating frame 2, the lifting work of the lifting motor 53 is stopped by the controller, and the spring bars are immersed in the cleaning liquid for cleaning.

[0029] During cleaning, the rotating motor 21 drives the rotating frame 2 to rotate, and the rotating frame 2 drives the moving frame 3 to rotate, stirring the cleaning liquid, and driving the elastic bars to be centrifugally cleaned. At the same time, the ultrasonic wave of the ultrasonic cleaning box 1 performs ultrasonic cleaning on the elastic bars with strong ultrasonic oscillations. The flushing nozzle 11 flushes the elastic bars in the moving frame 3 from multiple angles, and a combination of multiple cleaning methods is used for cleaning, thereby increasing the impact of the water flow on the elastic bars, and improving the comprehensiveness and cleaning effect of the elastic bars.

[0030] After cleaning is completed, the lifting motor 53 drives the winding shaft 51 to rotate forward, and the moving frame 3 is moved upward from the rotating frame 2 to the drying chamber 41. After the position sensor 33 detects that the moving frame 3 is moved into position in the drying chamber 41, the lifting motor 53 is stopped by the controller, and the spring bar uses the air intake fan 45 to introduce hot air into the drying chamber 41 for drying. The part not described in detail in the utility model is the prior art, so it is not elaborated here.
