Detector and detecting method for three parameters of escalator

Abstract

Disclosed are a detector and detecting method for three parameters of an escalator. The detector for the three parameters of the escalator comprises a main test device, a secondary test device, a laser range finder and an electric box, the secondary test device comprises a fixing base, suckers, a fixed disc, a movable disc and emitting and receiving heads, three end portions of the fixing base are respectively provided with one sucker, the fixed disc is perpendicularly fixed in the middle of the fixing base, the included angle between the center line of the fixed disc and the center line of an upper transverse pipe of the fixing base ranges from 32 degrees to 42 degrees, one side of the fixed disc is connected with the movable disc, the top of the movable disc is provided with a probe frame, and the emitting and receiving heads are fixed at the two ends of the probe frame; the main test device and the secondary test device are identical, and the laser range finder and the electric box are further fixed on the probe frame of the main test device; a steel wire rope is connected between the main test device and the secondary test device. The three parameters of the escalator can be automatically detected, and authority, scientificity, seriousness and authenticity of an examining report are guaranteed.

Description

Technical field: [0001] The invention relates to a detection instrument and a detection method of an escalator. Background technique: [0002] At present, the detection of the three operating parameters of the escalator, the stop distance, the deviation of the operating speed, and the synchronization of the handrail, is generally carried out by using the traditional manual measurement method of marking the line pendant, visually measuring the timing, and measuring the distance with a tape measure. The disadvantages of this method are: The measurement accuracy is poor, and the same escalator will be tested by different testers, resulting in different results, which will raise questions about the authority, scientificity, and seriousness of the test report, and reduce the persuasion to users. In addition, Due to the different light intensity and noise conditions of the test environment, the same tester and the same escalator will also test different results, which makes the te...

Problems solved by technology

[0002]At present, the detection of the three operating parameters of the escalator, the braking distance, the operating speed deviation, and the synchronization of the handrails, is generally marked with a line drop, and visually used for timing. The traditional manual measurement method of measuring the distance with a tape measure has the disadvantages of poor measurement accuracy, and the same escalator will be tested by different testers, resulting in different results, which will affect the authority, scientificity, and integrity of the test report. Seriousness raises doubts, and the persuasion to users will also be reduced. In addition, due to the different light intensity and noise conditions of the test environment, the same tester and the same escalator will also test different results, which makes testers and users more at a loss. Know which test results to confirm are correct
