Description

Technical Field

[0001] This utility model belongs to the field of railway locomotive maintenance technology, specifically relating to a paint removal and drying device for the axles of Harmony series locomotives. Background Technology

[0002] During the daily inspection and maintenance of rail locomotives, the axles of the Harmony series locomotives, as an important component of the running gear system, are coated with a layer of polyurethane paint topcoat and pink primer. During the inspection and maintenance process, the coating on the axle surface must be thoroughly removed to facilitate flaw detection and maintenance. The traditional cleaning method involves manually applying paint remover, which is inefficient, labor-intensive, and the surface is prone to rust after cleaning. The maintenance process also requires grinding.

[0003] Chinese utility model patent application number 202221675928.6 discloses a locomotive axle paint removal and cleaning device, including an automatic axle rotation mechanism and a high-pressure water gun lateral movement mechanism. The high-pressure water gun lateral movement mechanism is located on one side of the automatic axle rotation mechanism. The automatic axle rotation mechanism includes a drive frame at the front end; a storage rack with equal spacing is provided at the rear end of the drive frame; a geared motor and coupling for driving are fixedly connected to the top surface of the drive frame; the storage rack consists of two platform supports with equal spacing at the front and rear. This device, through the combined use of the automatic axle rotation mechanism and the high-pressure water gun lateral movement mechanism, allows the high-pressure water jet to be precisely positioned to the paint removal area of ​​the locomotive axle via the high-pressure water gun lateral movement mechanism. Simultaneously, in conjunction with the automatic axle rotation mechanism, the rotational movement of the locomotive axle completes the all-around cleaning and paint removal operation on the axle surface. However, the device in this application can only perform paint removal and cleaning on the axles of a single locomotive model, and cannot meet the needs of paint removal and cleaning on axles of multiple locomotive models. Furthermore, the device cannot prevent rusting after axle cleaning. Therefore, it is necessary to develop a multi-functional device that can simultaneously meet the needs of cleaning and paint removal, and effectively prevent rusting after axle cleaning. This is of great significance for achieving efficient and high-quality maintenance of the axles of the Harmony series locomotives. Utility Model Content

Then, the centering mechanism 7 is activated, and the positioning plate 74 extends to contact the axle 3, adjusting it to the centered position. Afterward, the positioning plate 74 retracts. At this point, the sliding mechanism 6 is activated, allowing the axle 3 to travel along the slide rail 61 to the rotary lifting mechanism 5. Then, the hydraulic cylinder 51 is activated to lift the axle 3 from the loading rack 63 and move it until the axle axis is coaxial with the limiting device 4. At this point, the limiting device 4 extends a specified length according to the axle 3 model to align with the axle. 3. Set a fixed limit to prevent axial movement of the axle 3 during rotation; finally, adjust the height of the cleaning water pipe 12 and the air drying pipe 13 according to the model of the axle 3, and start the guide rail module 2 to make the nozzles of the cleaning water pipe 12 and the air drying pipe 13 run along the linear guide rail 21 to the designated position. Then, the high-pressure cleaning function of the cleaning water pipe 12 is automatically started to remove paint. At the same time, the axle 3 is rotated by the rotating lifting mechanism 5 to perform all-round paint removal operation on the axle 3. After cleaning is completed, switch the high-pressure air drying function of the air drying pipe 13 to perform all-round air drying operation on the axle 3.
