Abstract
The present invention relates to a kind of dumb waiter layer door locking methods of inspection, include the following steps：Judge whether the layer door of detection meets three conditions of 2012 appendix As 6.7 of TSG T7006, if meeting three conditions, then when examining, whether there are two locked positions for observation layer door lock, gently closed layer door, when the locking element of layer door is in first locked position, phase down layer door, start elevator, locking element is set to enter second locked position if elevator cannot be run, elevator can normally start when locking element enters second locked position, then passes through inspection；If being unsatisfactory for any one condition in three conditions of 2012 appendix As 6.7 of TSG T7006, when detecting, emergency unlocking device is operated with key, door lock is made to be detached from locked position, started elevator and pass through inspection if elevator cannot be run.The dumb waiter layer Men Jun examined through the invention meets the technical standards requirement.
Description
Technical field
The present invention relates to elevator inspection technology fields, more particularly to a kind of dumb waiter layer door locking method of inspection.
Background technology
《Elevator surveillance is examined and periodic inspection rule-dumb waiter》(TSGT7006-2012) --- new inspection rule are
It is implemented on July 1st, 2012.Wherein A6.7 requires the dumb waiter being mounted in the region that can enter of the public, be unsatisfactory for
Any one lower condition：1. normal speed≤0.63m/s；2. open the door height≤1.2m；3. stop sill away from ground level >=
When 0.70m, dumb waiter layer door locking should electrically be confirmed by electric safety device.
In existing checkout procedure, such a door lock is found, layer door locking has electrical validation, but electrical safety fills
The contact set is on layer door lock hook, and layer door lock hook is mounted on well enclosure, another contact is also fixedly mounted on well enclosure
On, although form upper layer door locking has electrical validation in this way, its requirement not met the technical standards, because of this door lock
Structure will appear, and stick together once electric switch contact occurs, and when layer door is opened, safety return circuit is still in on-state, electricity
Ladder can be with normal operation, it is easy to occur to squeeze or shear accident.Therefore a kind of new method of inspection is needed to avoid above-mentioned feelings
The generation of condition.
Invention content
Technical problem to be solved by the invention is to provide a kind of dumb waiter layer door locking methods of inspection, can meet skill
The requirement of art standard.
The technical solution adopted by the present invention to solve the technical problems is：A kind of dumb waiter layer door locking inspection party is provided
Method includes the following steps：Judge whether the layer door of detection meets three conditions of TSGT7006-2012 appendix As 6.7, if together
When meet three conditions, then when examining, whether observation layer door lock there are two locked position, gently closed layer door, when the lock of layer door
When tight element be in first locked position, phase down layer door, startup elevator, make if elevator cannot be run locking element into
Enter second locked position, elevator can normally start when locking element enters second locked position, then passes through inspection；Such as
Meet three conditions when fruit difference, then when detecting, operates emergency unlocking device with key, so that door lock is detached from locked position, open
Dynamic elevator passes through inspection if elevator cannot be run.
Further include whether observing the locking action of each inlay door locking device by gravity, permanent magnet before being detected
The step of either spring is generated and is kept and when permanent magnet or spring failure, and gravity can not cause to unlock.
Further include when lift car is not in this stop, by firmly opening in the case of door locking before being detected
The step of validity of the door to test locking.
Advantageous effect
Due to the adoption of the above technical solution, compared with prior art, the present invention having the following advantages that and actively imitating
Fruit：The present invention requires to carry out in different ways by judging whether dumb waiter meets TSGT7006-2012 appendix As 6.7
It examines, to ensure that inspection result can meet the technical standards requirement.
Specific implementation mode
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, people in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
Embodiments of the present invention are related to a kind of dumb waiter layer door locking method of inspection, specifically include following steps：
1, estimate door lock structure, observe each inlay door locking device locking action whether by gravity, permanent magnet or
Person's spring is generated and is kept, and when permanent magnet or spring failure, gravity can not cause to unlock, if gravitation energy causes out
Lock, then examine and do not pass through, otherwise upchecks into next step.
2, it when lift car is not in this stop, is firmly opened the door in the case of door locking to test the validity of locking.
When 3, corresponding to while meeting three conditions of TSGT7006-2012 appendix As 6.7, the locking of layer door can not be by electricity
Device of air electrically confirms.But it is required that when car sails out of out onlocking zone, locking element should be automatically closed, and in addition to normally locking
Outside position, no matter confirm whether the electric device that layer door is closed works, it all should be at least there are two locked position.It is wanted according to these
It asks, whether observation layer door lock is there are two locked position in inspection, gently closed layer door, when layer door locking element is in first
When locked position, phase down layer door starts elevator, and at this moment elevator cannot be run, and locking element is made to enter second locking position
It sets, when locking element enters second locked position, elevator can normally start, then pass through inspection.
It is noted that above-mentioned steps can be completed by automated system, wherein layer can be obtained by video camera
The locked position of door lock, by motor drive mechanism realize gently closed layer door the step of, using limit switch come trigger layer door and electricity
Ladder, i.e., when limit switch detects that locking element enters the first locked position, triggering motor drive mechanism makes layer door phase down,
Then triggering elevator switch is to start elevator, and when locking element enters the second locked position, elevator, which normally starts, then to be sent " 1 "
To computer, " 0 " is sent if elevator cannot normally start to computer, computer can judge according to " 0 " or " 1 " received
Whether inspection is passed through.
4, when that cannot meet three conditions of TSGT7006-2012 appendix As 6.7 simultaneously, the locking of layer door should be by electrical
Safety device electrically confirms.When detection, emergency unlocking device can be operated with key, so that door lock is detached from locked position, start electricity
Ladder passes through inspection if elevator cannot be run.
It is not difficult to find that the present invention requires to use by judging whether dumb waiter meets TSGT7006-2012 appendix As 6.7
Different modes are tested, to ensure that inspection result can meet the technical standards requirement.
