A three-way speed synchronous detection method for escalators/moving walks

Abstract

The invention discloses a three-path speed synchronous-detection method for an escalator / moving walk. The method is characterized in that the method is used for detecting a deviation between the nominal speed and actual running speed of the escalator, acceleration during starting, deceleration during braking, a synchronous rate between hand straps on the two sides and steps / pedals, a hand strap deviation protection function, a stopping distance and the like according to requirements for each running index of the escalator and the moving walk in GB 16899-2011 safety rules for the construction and installation of escalators and moving walks and a special equipment safety law TSGT7005-2012 regulation for lift supervisory inspection and periodical inspection-escalators and moving walks. The method is conveniently and rapidly operated, and is automatic in detection, intelligent in judgment and accurate and reliable in detection result.

Description

technical field [0001] The invention relates to the field of braking performance detection of escalators / moving walks, in particular to a three-way speed synchronous detection method for escalators / moving walks, that is, a three-way speed synchronous detection method for handrails on both sides and steps / pedals. Background technique [0002] With the rapid development of my country's subway public transportation, large shopping malls, airports and overpasses, the number of escalators / moving walks is also increasing. The escalator / moving walk safety accidents are on the rise rapidly. Emergency braking is the first measure to be taken when escalators / moving walks and other equipment fail. If the braking distance and deceleration during braking are unreasonable, passengers may fall and even endanger their lives. According to the national standard GB16899-2011 "Safety Specifications for Manufacture and Installation of Escalators and Moving Walks", the deceleration of the escala...

Problems solved by technology

Emergency braking is the first measure to be taken when escalators / moving walks and other equipment fail. If the braking distance and deceleration during braking are unreasonable, passengers may fall and even endanger their lives.

According to the national standard GB16899-2011 "Safety Specifications for Manufacture and Installation of Escalators and Moving Walks", the deceleration of the escalator during braking in the running direction should not exceed 1m / s 2 There are clear regulations on the braking distance of escalators at different nominal speeds; at the same time, the operation of the handrail lags behind the steps, which makes passengers lean back and cause falls, which is also one of the safety hazards of escalators

In the detection of escalators, in view of the above hidden dangers, the traditional marking method is mainly used for detection at present. The detection method relies on the subjective judgment of the inspectors, the detection accuracy is poor, and it is not scientific
