Problems solved by technology

However, the error caused by the vibration of the car and the divergence of the laser spot make the center position of the spot inaccurate, and the calibration of the CCD module must be completed by manual adjustment, which cannot be fully automated

Abstract

Disclosed are a device and a method for detecting elevator guide rail perpendicularity based on visual measurement. An elevator guide rail perpendicularity detecting robot is used for carrying a luminous ring perpendicularly mounted on the robot to travel on a guide rail, and a camera alignment ring is mounted at the bottom end of the guide rail to input camera images into a computer. Circle center coordinates of the luminous ring and the height of a corresponding luminous ring are precisely calculated, and then a change curve of the perpendicularity of an elevator to be measured is drawn and is displayed on a display screen of the computer in real time. By the aid of full-automatic intelligent detection, errors caused by laser imaging are avoided, and errors caused by manual intervention are decreased. Operation is convenient, detecting precision is high, and calculating speed is fast. The device and the method are applicable to various places, and can be applied to not only detecting the perpendicularity of the elevator at installation and maintenance stages, but also detecting torsion of the guide rail and detecting rails, circular parts and the like in other industries.

Description

technical field [0001] The invention relates to the technical field of visual measurement of verticality of elevator guide rails, in particular to a detection device and method for verticality of elevator guide rails based on visual measurement. Background technique [0002] With the development of the elevator industry, more and more elevators are used, and elevator safety accidents occur from time to time, which puts forward higher requirements for the safety of elevators. The verticality of the elevator guide rail is an important guarantee for the safe, reliable and stable operation of the elevator. It has always been a technical problem to detect verticality during elevator installation and operation. The traditional method is the vertical line method, which requires manual intervention, and the reference must be re-fixed every time a position is measured, the measurement efficiency is low, and the error is large. Especially in the elevator maintenance process, due to ...
