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

Embodiment Construction
[0034] The three-way speed synchronous detection method for escalator / moving walk provided in the present embodiment is carried out according to the following process:
[0035] Step 1. Install the left handrail speed measuring mechanism and the right handrail speed measuring mechanism respectively, which is to press the handrail speed measuring mechanism on the handrail to realize the speed detection of the two-way handrail; install the step speed measuring mechanism by using the steps and step speed measuring wheels The friction between them drives the step speed measuring wheel to rotate to realize the speed detection of the steps.
[0036] The handrail speed measuring mechanism and step speed measuring mechanism in this embodiment adopt the related technology disclosed in the utility model patent No. ZL201220746689.9. Its handrail speed measuring mechanism is the handrail speed measuring device referred to in the utility model patent, and its step speed measuring mechanism ...

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...
