In order to ensure safe and stable operation of the elevator, the perpendicularity deviation, the track gauge deviation, the coplanarity deviation and the like of the elevator guide rail need to be detected regularly. The traditional guide rail detection technology mainly comprises the following steps: (1) The perpendicularity of the guide rail is detected manually point by adopting a gravity line drop or a plumb standard instrument; (2) The track gauge deviation and the coplanarity deviation are manually measured point by adopting a track calibrating ruler.
The traditional technology detection can not simultaneously measure the double-track gauge deviation, the double-track coplanarity deviation and the single-track perpendicularity deviation; most of the detection results are judged by naked eyes, and the error is large; the elevator needs to be manually controlled at the top of the elevator car to conduct point-by-point measurement, the detection efficiency is low, the error is large, the input of labor is large, the elevator needs to be operated back and forth at the top of the elevator car, and certain potential safety hazards exist.
