AI Technical Summary

Technical Problem

In existing elevator guide rail flatness testing equipment, the laser pointer cannot guarantee a centered position, and the second C-shaped frame cannot be connected to guide rails of different widths, resulting in poor testing results.

Method used

The system employs a mounting shell and U-shaped frame structure. The clamping plate is opened by the cooperation of the gear shaft and rack. The motor drives the bidirectional lead screw to rotate, so that the mounting plate contacts the outer wall of the guide rail, ensuring that the laser light assembly is centered. The limiting structure reduces offset.

Benefits of technology

This improves the accuracy and stability of elevator guide rail flatness detection, reduces deviation during the detection process, and enhances the detection effect.
