Elevator guide rail quality detecting device and method

Abstract

The invention relates to an elevator guide rail quality detecting device which comprises two plumb lasers independently fixed on the ground, a reflector and a camera. The reflector is fixed below thebottom bodies of grippers on the two sides of an elevator guide rail crawling robot; the camera is fixed on the inner side of a stabilizing arm unit; a pair of traction wheels and a pair of gripper wheels of the elevator guide rail crawling robot always cling to the elevator guide rail and crawl along the guide rail; the laser rays of the plumb lasers separately shine to the positions near to thecenter of the reflector; the camera shoots laser points generated on the reflector without stop; guide rail quality variation is directly converted into position changes of the reflector and the camera in the horizontal direction; and the straightness and other quality conditions of the elevator guide rail can be measured through treating each crawling information of the robot and the position data of the laser points. The elevator guide rail quality detecting device is convenient to use and mount and easy to operate, and has the advantages of being low in cost, high in resolution, measuring precision and efficiency and wide in building applicable range.

Description

technical field [0001] The invention belongs to the technical field of elevator guide rail quality inspection, and relates to an elevator guide rail quality inspection device and method. Background technique [0002] With the development of the times, the number of high-rise buildings has increased dramatically, and elevators have become the only way and means to transport people and materials to places with higher floors in most cases. Therefore, the safe operation of elevators is very important. The safe operation of the elevator is closely related to the quality of the elevator guide rail. A high verticality elevator guide rail can improve the running speed and safety of the elevator and improve the transportation efficiency of the elevator. But in the process of elevator installation and maintenance, how to monitor to ensure the quality of elevator guide rails with high verticality is difficult to solve, and it is difficult to achieve sufficient accuracy. There is no sc...

Problems solved by technology

However, in the process of elevator installation and maintenance, how to monitor to ensure the quality of elevator guide rails with high verticality is difficult to solve, and it is difficult to achieve sufficient accuracy

There is no scaffolding in the elevator room, so manual work is difficult to measure the flatness quality parameters

In recent years, there is a technique of using a vertical laser beam to measure the quality of elevator guide rails, but there are few highly automated methods, and many existing technical measurement methods are cumbersome, inefficient, and expensive
