[0002] Elevator guide rails are elevator components composed of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails, and are available in three cross-sectional shapes: T-shaped, L-shaped, and hollow. While providing guidance, the guide rails also withstand the impact forces during car and elevator braking, as well as the impact forces during emergency braking of the safety brake. Elevator guide rail processing refers to the process of shaping the guide rail material into the required shape and size for elevator operation using specific processing equipment and techniques. To improve the processing efficiency of elevator guide rails, a surface roughening treatment device is needed. However, existing surface roughening treatment devices still have the following shortcomings:

[0003] When existing surface roughness treatment devices are used, most of them are not convenient to adapt to the size of elevator guide rails for adjusting the position of the grinding parts, which limits their use and leads to a decrease in practicality and efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a surface roughness treatment device for elevator guide rail processing. Utility Model Content
