Traditional manual grinding suffers from low efficiency and poor consistency. Sandblasting technology achieves automated surface treatment through high-speed abrasive impact, which can effectively remove defects such as oxide scale and welding slag, while forming a uniform roughness to improve coating adhesion.

[0003] However, it still has some drawbacks. For example, the internal volume of the existing equipment used for sandblasting and grinding the surface of bogie steel beams is fixed, which cannot be adapted to the needs of different sized workpieces or operating scenarios, resulting in poor equipment flexibility and low space utilization.

[0004] To address the aforementioned issues, this application proposes a sandblasting and grinding device for the surface of bogie steel beams. Utility Model Content

[0023] Working principle

[0024] A liftable extendable top cylinder 4 of a bogie steel beam surface sandblasting and polishing device provides the main body 1 of the sandblasting and polishing device with the function of expanding its internal volume, thereby adapting to different usage scenarios. The lifting and lowering operation of the extendable top cylinder 4 is simple, which not only effectively improves the space utilization of the equipment, but also allows for flexible adjustment of the internal capacity according to actual operation needs. The entire operation process is time-saving and labor-saving. In use, the air source is connected through the air inlet 22 of the air supply device 21, and the compressed gas is delivered to the sandblasting device 25 through the high-pressure air pipe 24. After the abrasive and gas are mixed in the sandblasting device 25, they are sprayed out through the spray gun pipe 27 to sandblast and polish the surface of the bogie steel beam. The pressure gauge 23 is used to monitor the air pressure in real time. The bracket 2 and the moving wheels 3 facilitate the movement and positioning of the equipment.

[0025] When adjusting the height, the operator must simultaneously pull outwards the locking adjustment handles 5 on both the front and rear sides of the liftable extension cylinder 4. The pull rod 51 drives the horizontal plate 52 to move backward, causing the fixing block 53 to disengage from the lifting limit groove 11. At this time, the return spring 55 is compressed and stored. Then, by moving the handle 42, the liftable extension cylinder 4 is pushed up or down, causing it to slide along the lifting limit groove 11 of the main body 1 of the sandblasting and grinding device. The first sealing layer 12 and the second sealing layer 13 always remain tightly fitted to ensure sealing. After adjusting to the target position, the locking adjustment handle 5 is released, and the return spring 55 pushes the horizontal plate 52 to reset, causing the fixing block 53 to re-engage into the corresponding positioning hole of the lifting limit groove 11, thus completing the height locking and flexibly adapting to different working conditions.
