Device and method for calibrating movement speed of elevator speed limiter

Abstract

The invention provides a device for calibrating the movement speed of an elevator limiter. The calibration device comprises a driving speed regulation module, a first movement testing module, a second movement testing module, a data processing module, a speed measurement module and a displaying module, wherein the data processing module is used for receiving the signals of the first movement testing module and the second movement testing module in real time and controlling the driving speed regulation module, the displaying module is connected with the data processing module, the first movement testing module and the second movement testing module are respectively connected with the data processing module through signals, and the driving speed regulation module is connected with the data processing module through signals. The device for calibrating the moving speed of the elevator limiter solves the problem that traditional manual-operated calibration is inaccurate, large in calibration error and low in calibration precision. Meanwhile, the device for calibrating the movement speed of the elevator limiter is simple to operate and convenient to carry and has wide application prospects. Further, calibration reports can be obtained immediately after calibration. The invention further provides a method for calibrating the movement speed of the elevator limiter. With the method, reliable and accurate calibration results can be obtained rapidly, and the calibration quality of the elevator speed limiter is improved.

Description

technical field [0001] The invention relates to the technical field of elevator detection, and more specifically, to a detection device and a detection method for an elevator speed governor. Background technique [0002] As an important part of modern infrastructure supporting projects, elevators are closely related to national economic construction, especially the development of real estate and the improvement of people's quality of life. With the development of the economy, the number of elevators has increased rapidly. Although the relative accident rate is not high, the number of accidents still has an increasing trend. Especially, elevator stall accidents are very harmful and account for a large proportion of elevator accidents. Elevator speed limiter-safety gear linkage system is the most critical protection when the elevator stalls. Among them, the speed limiter is the safety component of the elevator. Its function is to monitor and control the speed of the car at any...
