Specific embodiment
Shown embodiment is further described to this utility model below in conjunction with the accompanying drawings.
Embodiment one：A kind of for supporting elevator subtract stroke buffers to realize control deceleration of elevator elevator subtract stroke delay
Rush the supporting deceleration device of device, it is connected with the panel MCB7 of elevator.
Above-mentioned one basic scheme of supporting deceleration device is：This supporting deceleration device includes two deceleration trigger switch
SUP and SLP, car speed detector, the first relay, speed monitoring plate MCB3, the second relay, subtract safety travel module
A71.Two deceleration trigger switch SUP and SLP are respectively arranged at the correct position at the upstation of elevator hoistways and lower end station, it
Can disconnect when the car of elevator reaches its position, meanwhile, this two deceleration trigger switch SUP and SLP are serially connected in
In the safety return circuit of elevator.Car speed detector using the absolute value encoder controller on the car being arranged on elevator, it
For detecting the speed of service of the car of elevator.Speed monitoring plate MCB3 passes through RS485 communication interface with car speed detector
It is connected, the speed of service that it is used for the car according to detected elevator controls the first relay on-off, when elevator
When the speed of service of car exceedes the permissible velocity of wherein setting, speed monitoring plate MCB3 controls the first relay to disconnect, otherwise
First relay closure.Speed monitoring plate MCB3 is connected with the panel MCB7 of elevator also by CAN.The control of elevator
Plate MCB7 realizes the velocity measuring of the driving means of elevator by the encoder of its traction machine, and the second relay is then by elevator
Controller MCB7 controls break-make according to the speed of service of the driving means of elevator, when the speed of service of the driving means of elevator surpasses
Cross wherein setting permissible velocity when, the panel MCB7 of elevator controls the second relay to disconnect, otherwise the second relay closure.
Above-mentioned first relay and the second relay are in series and are linked into and subtract safety travel modules A 71, and this subtracts safety travel modules A 71
In there is a bypass, this bypass is connected to the two ends of two deceleration trigger switch SUP being in series and SLP, thus this bypass energy
Enough on demand two deceleration trigger switch SUP that short circuit is in series and SLP, and subtract safety travel modules A 71 then according to mutually concatenating
The signal of the first relay and the second relay control whether using bypass two deceleration trigger switch SUP and SLP are carried out short
Connect.
The operation principle of above-mentioned this supporting deceleration device is：Lift car runs to any one deceleration trigger switch
During SUP or SLP position, if the speed of service of lift car is detected not less than permissible velocity, the first relay closure, if inspection
Measure elevator driving means the speed of service not less than permissible velocity then second relay closure, thus be in series first continues
Electrical equipment and the second relay, to subtracting safety travel modules A 71 output signal, subtract safety travel modules A 71 and are adopted according to this signal
Its bypass carries out short circuit to them before deceleration trigger switch SUP or SLP disconnect, and elevator safety loop makes elevator normally run.
If lift car runs to deceleration trigger switch SUP or SLP position, the speed of service of lift car and/or the driving of elevator
Device is too high and exceed corresponding permissible velocity, then the first relay and/or the second relay disconnect, and now subtract safety travel mould
Block A71 will not two deceleration trigger switch SUP of short circuit and SLP, so cut off when deceleration trigger switch SUP or SLP disconnect
The safety return circuit of elevator, band-type brake stops elevator immediately, is slowed down by band-type brake and ensures elevator before contact elevator subtracts stroke buffers
Speed be less than the desin speed of buffer it is ensured that elevator safety.
In order to improve elevator safety performance further, the present embodiment is set up superfluous on the basis of above-mentioned supporting deceleration device again
Leaving velocity degree monitoring scheme, as shown in Figures 1 and 2, this supporting deceleration device also includes two speed detection switch in advance
S15U and S15L, detection switch S15U and S15L are also respectively arranged at upstation and the lower end of elevator hoistways to this two speed in advance
Stand place, and at upstation, detection switch S15U is arranged on the lower section of deceleration trigger switch SUP, in lower end station to speed in advance
Place, detection switch S15L is arranged on the top of deceleration trigger switch SLP to speed in advance.Two speed in advance detection switch S15U and
S15L is connected to subtract safety travel modules A 71 and when the car of elevator reaches device position to subtracting safety travel module
A71 sends signal, and subtracts the panel MCB7 that safety travel modules A 71 is additionally coupled to elevator, subtracts safety travel modules A 71 basis
Detection switch S15U exports with the signal of the first relay mutually concatenating and the second relay speed with the signal of S15L in advance
Force reduce-speed sign to the panel MCB7 of elevator.
The operation principle that this has the supporting deceleration device of honor redundancy speed monitoring scheme is：
（1）Elevator normal run action principle
When elevator normal upstream or the descending operation toward end station, in arrival rate detection switch S15U or S15L position in advance
Put car speed normal, now first relay of the panel MCB7 of speed monitoring plate MCB3 and elevator and the second relay are defeated
Go out adhesive, then in Fig. 1 subtract safety travel modules A 71 relay work output short circuit deceleration trigger switch SUP and SLP and
Make deceleration trigger switch ineffective, they disconnect when car is through deceleration trigger switch SUP or SLP, but are subtracted stroke
Security module A71 exports short circuit, and the safety return circuit of elevator normally makes elevator normally run, and accompanying drawing 3 is that elevator is normal to be run
Sequential chart.
（2）Elevator abnormal running operating principle
If elevator occurs abnormal, that is, through speed, detection switch S15U or speed during S15L are more than and correspond to car in advance
At this setting speed V, now subtract safety travel modules A 71 can export one force reduce-speed sign to panel MCB7 notify
Converter slows down, when car reaches deceleration trigger switch SUP or SLP position, if car speed is less than the specified speed of buffer
Degree（The namely actuating of relay arranges speed V）When, subtract safety travel modules A 71 output action short circuit deceleration trigger switch SUP
And SLP, elevator normally slows down stopping, if contrary when deceleration trigger switch SUP or SLP speed be still more than V, subtract stroke
Security module A71 also would not short circuit deceleration trigger switch SUP and SLP, such deceleration trigger switch SUP or SLP disconnect and cut
Disconnected safety return circuit, band-type brake parking immediately, the design ensureing that the speed before contact buffer is less than buffer of being slowed down by band-type brake
It is ensured that elevator safety, accompanying drawing 4 is abnormal operation of elevator sequential chart to speed.
Such scheme uses to subtract and meets the manufacture of GB 7588-2003 elevator during stroke buffers and install safety standard mark
Accurate 12.8 requirement, subtracts safety travel module, is installed in hoistway trigger switch of slowing down up and down, upper and lower end station speed by increasing
The devices such as pilot switch, the absolute encoder speed detector detecting for car speed to complete to drive master to elevator jointly
The normal control function slowing down of machine, meets terraced rate request, the requirement to pit, headroom height for the standard also meeting at a high speed, protects
Card elevator safety operation.
Above-described embodiment is only that technology design of the present utility model and feature are described, its object is to allow and is familiar with technique
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalence changes made according to this utility model spirit or modification, all should cover protection domain of the present utility model it
Interior.
