Unexpected car movement protection systematic difference scene of the present utility model is pre- enabling and flat bed application again, below
It is briefly described respectively：
Pre- open the door is the technology of elevator advance door opening before the floor that achieves the goal, compared to being opened again after the floor that achieves the goal
Door, pre- open the door have the advantages of improving elevator Use Limitation, and on the premise of pre- open the door, lift car still needs to move
To purpose floor flat bed normal place, this when, it is necessary to which lock carries out short circuit on the door；
Flat bed is that a little skew can occur for car position after elevator contains recurrence change again, for example personnel are reduced, sedan-chair
Railway carriage or compartment rises several millimeters to tens millimeters, and personnel increase weight, several millimeters to tens millimeters of cage descending, in the situation that this gate is opened
Under, the process that lift car is returned to flat bed is referred to as flat bed again, this when, it is also desirable to which lock carries out short circuit on the door.Work as elevator car
When operation is arrived at a station, when UCMP (LSP01) module detects that again flat bed signal 1 (FL1) is effective, its corresponding contacts is moved in railway carriage or compartment
Make；When detecting down that again flat bed signal 2 (FL2) is effective again, the action of its corresponding contacts, while area's signal input SX1 can be caused
(X2) effectively, when apparatus for controlling elevator mainboard detects area's signal, relay Y3 (SY) will be exported, in the upper signal of flat bed again 1
In the case of flat bed signal 2 and SY signals are simultaneously effective again with, UCMP (LSP01) output advance door opening signal SX2 (X8), when
Elevator device detects advance door opening signal SX2 (X8) effectively, while seals up a door and lock work, short circuit door lock, i.e. short circuit JAQ-MS,
Realize the function of advance door opening.Action sequence is shown in Figure 2, and operation principle is shown in Figure 3.
The unexpected protection course of work of unexpected car movement protection system of the present utility model is as follows：When control system is realized
After advance door opening, SY signals disconnect, and closure door lock signal disconnects.After if car arrived at a station, UCMP (LSP01) module closure door
Afterwards, cage door lock open, but for some reason the non-stop of car and continue to run with, when UCMP (LSP01) module detects
Again flat bed signal 1 (FL1) or under again flat bed signal 2 (FL1) disconnect, force disconnect door lock shorted section, band-type brake contactor dead electricity,
Main frame braking of brake car, realizes that car is surprisingly protected.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
