[0002] Rail transit such as trains, subways, and light rails are gaining more and more attention due to their advantages such as large capacity and high speed, and the safety of corresponding rail transit equipment is also receiving more and more attention. Train wheel hub axles are used to connect the wheels of trains and are key components to ensure the operation of trains. Train wheel hub axles are generally produced by casting. In order to ensure the quality of each axle, it is necessary to perform flaw detection on the train wheel hub axles. At present, the most commonly used flaw detection method is mainly magnetic particle flaw detection, which is a non-destructive testing method to detect defects on the surface or near the surface of ferromagnetic materials by accumulating magnetic particles in the leakage magnetic field near the defects. A flaw detection method in which workpieces made of magnetic materials such as steel are magnetized, and the leakage magnetic field at the defective part is used to absorb the magnetic particles, and the surface defects and near-surface defects of the detected object are displayed according to the distribution of magnetic particles.

[0003] When performing flaw detection, it is usually necessary to first spray magnetic powder liquid on the surface of the test piece to make the magnetic powder liquid contact with the surface of the workpiece. In order to make the magnetic powder liquid contact with the surface of the workpiece better, the surface of the workpiece usually needs to be cleaned. Train wheel axles are large in size, long in length, and heavy in weight. There is no special cleaning equipment. Usually, they are only cleaned manually by spraying before testing. Since train wheel axles are heavy and there is a lot of oil on the surface, it is difficult to clean them manually, which will affect the detection accuracy of the axles. Therefore, it is necessary to design a device specifically for cleaning the surface of train wheel axles during magnetic flaw detection. Utility Model Content

The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the utility model. However, those skilled in the art will appreciate that the technical solution of the utility model can be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted.

[0018] like Figure 1 , 2 As shown, the utility model discloses a surface cleaning device for a train wheel hub axle, the cleaning device comprises a cleaning box 1, two roller groups are arranged in the cleaning box 1, each roller group consists of two parallel rollers 14, the two roller groups are separated by a certain distance along the longitudinal direction of the cleaning box 1, the two roller groups are connected to the roller transmission mechanism, and the rollers 14 can be driven to rotate through the roller transmission mechanism. As an embodiment, as shown in the figure, the roller transmission mechanism comprises two transmission gears, the two transmission gears are respectively connected to the two rollers, the two transmission gears are connected through a transmission chain 15, one of the transmission gears is connected to a driving motor 16, and the driving motor 16 can drive the two rollers to rotate. When the cleaning device is in use, the train wheel hub axle 2 is placed on the two roller groups for support, and the train wheel hub axle 2 can be driven to rotate synchronously by rotating the rollers. The distance between the two roller groups can be adjusted to meet the cleaning requirements of train wheel hub axles of different lengths.

[0019] A spray pipe 6 is also provided in the cleaning box, and a plurality of spray heads 7 are provided on the spray pipe 6. The spray pipe 7 is arranged in the longitudinal direction of the cleaning box 1, which is the same as the arrangement direction when the train wheel hub axle 2 is cleaned. The spray pipe 7 is connected to the water tank 4, and the water tank 4 is arranged outside the cleaning box 1. A first water pump is provided in the water tank 1, and the first water pump is connected to the spray pipe through a pipeline. In this way, the surface of the train wheel hub axle 2 can be sprayed and cleaned through the spray pipe 6 and the spray head 7.

[0020] A cleaning brush 3 is also provided in the cleaning box, and the cleaning brush 3 is connected to a support shaft 13, and the support shaft 13 is connected to a roller brush driving mechanism, and the roller brush driving mechanism can drive the support shaft 13 to rotate. The roller brush driving mechanism is arranged on a screw transmission mechanism, and the screw transmission mechanism includes a screw rod 8 and a screw rod nut 10, and the roller brush driving mechanism is connected to the screw rod nut 10, so that the screw rod 8 can rotate to drive the screw rod nut 10 to reciprocate on the screw rod, thereby driving the cleaning brush 3 to move synchronously.

[0021] like Figure 3 As shown, as a preferred embodiment, the roller brush driving mechanism includes a first transmission wheel 11 and a second transmission wheel 12, the first transmission wheel 11 is connected to the driving motor, the first transmission wheel 11 and the second transmission wheel 12 are connected through a transmission belt 9, the first transmission wheel 11, the second transmission wheel 12 and the driving motor are arranged on a mounting seat, and the mounting seat is connected to the transmission nut 10. With this roller brush driving mode, during the spray cleaning process, the cleaning brush can be used to clean in the direction of the train wheel hub axle 2 in a rotating manner. Since the cleaning brush 3 and the train wheel hub axle 2 are both in a rotating state, especially for the train wheel hub axle 2 with more oil on the surface, it can achieve a better cleaning effect.

[0022] Since the amount of inspection required for the train wheel hub axle 2 is large, in order to save water, the cleaning fluid needs to be recycled. Repeated use of the cleaning fluid will contain a certain amount of oil and dirt. For this reason, an oil-water separation device 5 can be placed between the cleaning tank 1 and the water tank 4.
