Description

[0002] The high-speed rail coupling is a key mechanical component used to connect different rotating parts in the high-speed rail train power system. It can effectively transmit the power generated by the motor to the wheelset.

[0003] Cleaning the high-speed rail coupling before finished product packaging is a very important step. Its main purpose is to ensure the cleanliness of the coupling, extend its service life, guarantee performance, and meet the customer's quality requirements.

[0004] When cleaning the high-speed rail coupling, residual cutting fluid, coolant, metal chips, oil and dust in the production process can be removed. Existing high-speed rail couplings are usually cleaned by spraying, that is, a high-pressure spray gun is used to spray the cleaning fluid onto the surface of the coupling, and the impact force of the water flow is used to remove the oil, dust and other pollutants on the surface. However, the existing spray cleaning equipment can usually only spray the cleaning fluid onto the coupling surface from above. Although the spray pressure and spray angle can be adjusted to a certain extent, there are still some positions at the bottom of the coupling that cannot be cleaned, thereby reducing the effect of cleaning the coupling surface.

[0052] See also Figure 4 , Figure 5 and Figure 7 The clamping branch chain 453 includes a fixing frame 4531 with a U-shaped structure and an open end mounted on the inner wall of the rectangular frame 21. A plurality of lifting rods 4532 evenly distributed from left to right are slidably connected through the horizontal section of the fixing frame 4531. An inclined surface is provided at one end of the lifting rod 4532 close to the fixing frame 4531. A square plate 4533 is installed at one end of the lifting rod 4532 close to the supporting frame 32. A connecting spring 4534 sleeved on the outer periphery of the lifting rod 4532 is installed between the square plate 4533 and the fixing frame 4531. A cylindrical rod 4535 is installed at one end of the square plate 4533 away from the lifting rod 4532.

[0053] During specific operation, before cleaning, the second hydraulic push rod 451 is connected to the existing hydraulic pump in the outside world. The raised block 4523 is a right-angled trapezoidal structure and its slope faces the inclined surface on the corresponding lifting rod 4532. After the supporting frame 32 drives multiple couplings to rotate, the multiple water storage frames 442 are located directly above the supporting frame 32. The second hydraulic push rod 451 is started, and the second hydraulic push rod 451 drives the U-shaped push rod 4521 to move. The U-shaped push rod 4521 drives multiple raised blocks 4523 to move. The multiple raised blocks 4523 located above push the inclined surfaces of multiple lifting rods 4532 at corresponding positions above through their own slopes. The multiple lifting rods 4532 are forced to move toward the direction of the supporting frame 32 and drive the cylindrical rod 4535 to move through the square plate 4533. The square plate 4533 simultaneously stretches the connecting spring 4534. As the lifting rod 4532 moves, the cylindrical rod 4535 The column rod 4535 gradually enters the positioning countersunk hole 4413 at the corresponding position, thereby limiting the position of the movable plate 4411, and then limiting the position of the water storage frame 442, and then stopping the operation of the second hydraulic push rod 451, and then starting the water pump on the container filled with cleaning fluid, the water pump injects the cleaning fluid into the water inlet pipe 445, the water inlet pipe 445 injects the cleaning fluid into the corresponding water storage frame 442, the corresponding water storage frame 442 injects the cleaning fluid into the next water storage frame 442 through the connecting hose 444, and repeats this step until all the water storage frames 442 are filled with cleaning fluid, and at the same time, the cleaning fluid in the multiple water storage frames 442 is sprayed out through the corresponding multiple water spray heads 443 and sprayed onto the coupling, the cleaning fluid cooperates with the rotating receiving frame 32 to realize the function of cleaning the multiple couplings from above, and the cleaning fluid after cleaning falls into the sump 1 through the blanking through hole 22.

[0054] After the cleaning fluid cleans the multiple couplings from above for a period of time, the second hydraulic push rod 451 drives the U-shaped push rod 4521 to retreat, and the multiple protrusion blocks 4523 release the limit of the multiple lifting rods 4532. The connecting spring 4534 in the stretched state is reset and drives the cylindrical rod 4535 to move out of the positioning countersunk hole 4413 through the square plate 4533, thereby releasing the limit of the movable plate 4411, and the first electric slider 43 continues to move and drives the multiple water storage frames 442 to move to the vertical section of the U-shaped guide rail 41, and the multiple water storage frames 442 are between It is hinged to facilitate the turning and movement of multiple water storage frames 442. At this time, the first electric slider 43 moves to the lower end of the U-shaped guide rail 41, and then the second hydraulic push rod 451 drives the U-shaped push rod 4521 to re-feed, and the multiple positioning cylinders 4522 on the U-shaped push rod 4521 are plugged into and matched with the positioning countersunk holes 4413 at the corresponding positions, thereby realizing the function of limiting the moving plate 4411 after movement, and then positioning the water storage frame 442 on the side of the supporting frame 32, thereby realizing the function of cleaning the multiple couplings from the side with the cleaning liquid.

[0055] After the cleaning fluid cleans the multiple couplings from the side for a period of time, the second hydraulic push rod 451 drives the U-shaped push rod 4521 to retreat, and the multiple positioning cylinders 4522 are separated from the positioning countersunk holes 4413 at the corresponding positions. The first electric slider 43 continues to move and drives the multiple water storage frames 442 to move to the lower horizontal section of the U-shaped guide rail 41. The second hydraulic push rod 451 drives the U-shaped push rod 4521 to move, and the U-shaped push rod 4521 drives the multiple raised blocks 4523 to move. The multiple raised blocks 4523 located at the bottom face the corresponding positions at the bottom through their own slopes. The inclined surfaces of multiple lifting rods 4532 are pushed, and the multiple lifting rods 4532 are forced to move toward the receiving frame 32 and drive the cylindrical rod 4535 to move through the square plate 4533. The square plate 4533 stretches the connecting spring 4534 at the same time. As the lifting rods 4532 move, the cylindrical rod 4535 gradually enters the positioning countersunk hole 4413 at the corresponding position, thereby limiting the position of the movable plate 4411, and then limiting the position of the water storage frame 442, thereby realizing the function of cleaning the multiple couplings with the cleaning liquid from below.

[0056] The first electric slider 43 drives the multiple water storage frames 442 to move along the U-shaped guide rail 41, so as to realize cleaning of the coupling from multiple positions on the upper side and the lower side, effectively improving the cleaning effect of the coupling surface and avoiding the phenomenon that some positions on the coupling surface cannot be cleaned. After the cleaning liquid cleans the multiple couplings from below for a period of time, the second hydraulic push rod 451 drives the U-shaped push rod 4521 to retreat, and the first electric slider 43 drives the multiple water storage frames 442 to reset upward again. During the resetting process, the cleaning liquid continues to clean the coupling from multiple directions, effectively removing the surface of the coupling. The stains splashed during cleaning at other positions further improve the cleaning effect. When the multiple water storage frames 442 are moved to the top again, the injection of cleaning liquid is stopped, and the drive motor 53 is turned off. The two first hydraulic push rods 23 are started, and the two first hydraulic push rods 23 drive the sealing plate 25 to move upward through the lifting plate 24 and open the opening of the rectangular frame 21. The two second electric sliders 312 drive the receiving frame 32 to move and move out of the rectangular frame 21 through the U-shaped frame 313 and the rotating column. The operator takes out the cleaned coupling in the receiving frame 32, and the coupling cleaning is completed.
