Embodiment 1
In one embodiment of the utility model, a kind of anti-unintended car movement protection device is provided, referring to Fig. 1,
The protective device is corresponded with single fan layer door, each protective device includes the first fixing piece 1, the second fixing piece 4, first
2 and second rotating member 3 of rotating member, first fixing piece 1 are fixed on the well enclosure of the lower section of landing sill 5, and described the
Two fixing pieces 4 are fixed on layer door 6, and one end of first rotating member 2 is rotatably arranged on the first fixing piece 1,
One end of second rotating member 3 is rotatably arranged on the second fixing piece 4, the other end of first rotating member 2 and
The other end connection of two rotating members 3, as shown in Fig. 2, second fixing piece 4, the second rotating member 3, the first rotating member 2 and first
The height of fixing piece 1 is sorts from high to low, and in the present embodiment, second fixing piece 4 is fixed on the lower end of layer door, described
First fixing piece 1 is fixed on by bolt 10 on the well enclosure.
When the layer door 6 is opened, the second fixing piece 4 is moved to close to 1 direction of the first fixing piece, while the first rotating member
2 and second rotating member 3 rotate and be extending at least partially into the lower section of car sill 8,2 and second rotating member of the first rotating member
3 for limiting car, and the detailed process limited is as follows：
When layer door 6 is closed, the distance between the second fixing piece 4 and the first fixing piece 1 be maximum distance, first turn at this time
It is a straight line in overlook direction, as shown in Figure 3 although there are height relationships for 2 and second rotating member 3 of moving part；With layer
Door 6 is gradually opened, the shortening of the distance between the second fixing piece 4 and the first fixing piece 1, in this case, 2 He of the first rotating member
Second rotating member 3 necessarily rotates, and forms angle to the direction far from well enclosure, as shown in figure 4, first rotating member
2 and second rotating member 3 form the stent that support load is carried out to car 9, car 9 is prevented under 6 opening state of layer door to continue to moving down
It is dynamic.
Meanwhile car 9 moves up under 6 opening state of layer door in order to prevent, one in the utility model is preferred real
It applies in example, 8 lower section of car sill is equipped with car sill bracket 81, as shown in figure 5, being opened up on the car sill bracket 81
There is the mounting hole 82 to match with 2 and second rotating member 3 of the first rotating member, as shown in figure 4, when the second fixing piece 4 is to the
One fixing piece 1 close to when, the first rotating member 2 and the second rotating member 3, which rotate, to be formed the end of angle and stretches into the mounting hole
In 82, both car 9 can be prevented to move down, while can also under the support of the first rotating member 2 and the second rotating member 3 load in this way
Tissue car 9 moves up, because when car 9 moves up, 2 and second rotating member 3 of the first rotating member can be to fixation
The lower surface in hole 82 acts power.
Embodiment 2
In one embodiment of the utility model, a kind of elevator device is provided, including anti-car described in embodiment 1
Accidental movement protective device.
Except this, the system also includes car 9 and elevator controlling module, the elevator controlling module includes safety return circuit list
Member, if the safety return circuit disconnects, elevator controlling module control car is out of service.
While car accidental movement is prevented, it is also necessary to control when layer door is opened, safety return circuit is off.
Specifically realized using following means：Setting is opened for detection layers door or the detection switch 7 of closed state, the detection switch
7 are connected on and reach in safety return circuit (not shown), if the detection switch detects that layer door is opened, the detection switch is broken
It opens；If the detection switch detects that layer door is closed, the detection switch is closed.
Optionally, the detection switch is photoelectric sensor or range sensor.In elevators field, it is for detection layers door
The sensing detection technology of no closing is varied, numerous to list herein.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
