Elevator guide rail perpendicularity detection system based on vertical movement of lift car

An elevator guide rail perpendicularity detection system based on lift car vertical movement comprises a seat plate, a distance measuring sensor, a vertical guide rod, a controller and a prompting device. The seat plate is arranged on the vertical guide rod in a sliding mode and driven by a lift car, and the distance measuring sensor is arranged on the seat plate and used for detecting the distance between the distance measuring sensor and a guide rail face and sending distance information to the controller. The controller judges the distance information and controls the prompting device to give out a prompt when the detected distance changes along with movement of the lift car. By measuring the distance to the guide rail surface in real time, the perpendicularity problem of the guide rail is found in time, and elevator safety accidents are reduced. 基于轿厢垂直运动的电梯导轨垂直度检测系统，包括座板、测距传感器、竖导向杆、控制器、提示装置；所述座板滑动设置在所述竖导向杆上并由轿厢驱动，所述测距传感器设置在所述座板上并用于检测其与导轨面的距离并将距离信息发送至控制器，所述控制器判断距离信息并在所检测出的距离随轿厢运动而变化时控制提示装置发出提示。通过实时测定与导轨面的距
