Method for precisely testing brake distance of escalator

Abstract

The invention provides a method for precisely testing the brake distance of an escalator. The method includes the steps of S1, setting a testing instrument and a reference point; S2, using the testinginstrument to monitor the acceleration of the escalator; S3, when the acceleration variable of the escalator reaches a first critical condition, using the testing instrument to monitor and record thedistance between the testing instrument and the reference point; S4, when the distance variable between the testing instrument and the reference point reaches a second critical condition, using the testing instrument to monitor and record the final distance between the testing instrument and the reference point, and calculating the brake distance of the escalator. The method has the advantages that the brake distance of the escalator can be precisely tested, the distance errors of manual brake distance testing are lowered effectively, and brake starting time and ending time can be precisely captured and calculated.

Description

technical field [0001] The invention belongs to the technical field of special electromechanical equipment, and in particular relates to an accurate test method for the stopping distance of an escalator. Background technique [0002] Escalators are an indispensable means of transportation for the transportation of large-flow passengers in public places such as stations, shopping malls, and subways. In recent years, they have been widely used, and the number of escalators in my country has also increased rapidly. At the same time, escalator safety accidents also continue to occur; especially after the Shenzhen escalator retrograde in December 2010, the Beijing subway retrograde accident in July 2011, and the Hubei escalator accident in July 2015, the safety of escalators has been resolved. the focus of the whole society. [0003] During the operation of the escalator, the braking performance of the escalator and whether it can be braked in time will directly affect the sever...

Problems solved by technology

[0009] The purpose of the present invention is to overcome the large error in the artificial test braking distance in the above-mentioned prior art, and it is impossible to accurately capture the braking action, and it is impossible to accurately calculate the deviation of the speed through the real-time distance test to determine the starting moment of braking. To capture the defects of the braking action, this test method can accurately capture the braking action and stop moment by testing the running acceleration and running stroke of the escalator in real time, and can quickly obtain the braking distance and avoid human influence. The test result of this test method is accurate, Safe and convenient testing process
