Description
Technical field
The present invention relates to elevators fields and detection field, in particular to a kind of stair comb plate foreign matter protective device
Detection method.
Background technique
As China's public transport and megastore, station, airport, overpass etc. are fast-developing, escalator conduct
A kind of open Continuous Traffic tool, installation and usage amount are increasing, and escalator safety accident is also presented on quickly
The impetus risen.Such facility personnel is intensive and complicated, once accident occurs, it will bring serious consequence.In order to guarantee to multiply
The safety of visitor and the normal operation of escalator, China extremely payes attention to the safety of escalator, and has stringent specification.So
And escalator safety accident still happens occasionally.
The generation of all kinds of accidents in order to prevent is mounted with various safety guards on escalator, is guaranteeing staircase peace
Serve in terms of row for the national games particularly important.Escalator accident ratio, the clamping accident of step account for about certainly in recent years for analysis
41% or more of dynamic staircase accident, step clamping accident is mainly due to the failure of moving staircase apron plate safety device and fishback
The failure of foreign matter protective device causes, and the latter one account for very big ratio.Automatic staircase comb plate foreign matter protection safety device is
Guarantee escalator safe operation important link, the detection of security performance be one concerning on staircase passenger safety it is important
Inspection project.
Country's existing " elevator surveillance is examined and periodic inspection rule -- escalator and moving sidewalk " is for fishback
The protective item purpose method of inspection are as follows: remove the comb teeth at position among fishback；Make fishback backward with tool or move up (or
Front and back, up and down)；Examine whether safety switch acts, can escalator or moving sidewalk start.
This check system have following defects that even if examine when protective device can act (movement, refer to protective device energy
Enough trigger protection movements), but the difference between the fubaritic device action value and setting value.In other words, it only can determine that protection
Device can act, but can not determine whether protective device acts on suitable opportunity.
In addition, being pressed from both sides in existing another check system using object in the unit simulation actual use of special designing
Then whether effective whether the case where entering tyre tread plate and fishback act determining protective device according to protective device.This mode
Be limited in, the precondition that can be realized detection is that protective device can be operating normally.And dress is protected in simulation process
It sets once failure will be unable to effective action, to make running step directly and fishback shock, step is directly made when serious
It is damaged with detection device, there is biggish security risk.
Summary of the invention
The purpose of the present invention is to provide a kind of detection methods of stair comb plate foreign matter protective device, can not only detect
Whether stair comb plate foreign matter protective device effective, moreover it is possible to avoid in the detection process to relevant device (such as staircase, detection dress
Set) damage, improve detection accuracy.
The purpose of the present invention is what is realized by following technical measures:
The embodiment of the present invention provides a kind of detection method of stair comb plate foreign matter protective device, comprising:
Apply active force to fishback；
In response to the active force application and detect the value of at least one detection parameters；
According to the action state of the stair comb plate foreign matter protective device, at least one detection parameters value and
The threshold value of at least one detection parameters determines whether the stair comb plate foreign matter protective device is effective.
The invention has the following advantages over the prior art:
As long as changing industry thinks the traditional concept that fishback foreign matter protective device can act；By to fishback
Apply active force, and is helped according to the determination of the action state of stair comb plate foreign matter protective device, the value of detection parameters and its threshold value
Whether terraced fishback foreign matter protective device effective, can not only effectively avoid detection process to relevant device (such as staircase, detection
Device) damage that may cause, detection accuracy is also advantageously improved, and be suitable for evaluating stair comb plate in a manner of quantization different
The reliability of object protective device.
