Description
Technical field
The present invention relates to elevator safety technical field, specially a kind of elevator car safety device.
Background technology
The places such as cell, market, hotel, office building are lived in business, the elevator that can vertically run greatly facilitates people
Upper to go downstairs, elevator is played an important role in the life of people, but higher requirement is also proposed to its security；If elevator
Car it is vertical up or it is vertical it is descending during, fallen situation once there is stall, if do not had quickly
The precautionary measures of effect, consequence will be hardly imaginable.
The content of the invention
It is an object of the invention to overcome the shortcomings of that there is provided a kind of elevator car safety device, this electricity in background technology
Terraced car safety device, can fall situation to the stall that car occurs in time, quickly make a response, car is buffered to greatest extent
The impulsive force being subject to, improves the security of lift car operation.
To achieve the above object, the present invention provides following technical scheme：A kind of elevator car safety device, including elevator
Car moving up and down is provided with well, the elevator, the ground of the elevator is provided with the first air bag, the sedan-chair
The exterior bottom in railway carriage or compartment is provided with the second air bag, the car and is additionally provided with stall sensor, first air bag, second
Air bag and stall sensor are electrically connected to controller.
It is preferred that, the controller is PLC.
It is preferred that, the first air bag and the second air bag triggering can be full of the elevator of relevant position after opening
Space.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the elevator car safety device, by two corresponding air bags above and below setting, it is tight that reply car stall is fallen
Anxious situation, has cut down the impulsive force that car is subject to greatest extent, improves the security of lift car operation.
2nd, the elevator car safety device, the signal of stall sensor is received using PLC, and trigger automatically automatically
First air bag and the second air bag, overall process are automatically performed, and response is rapid, and sensitivity is high.
3rd, the elevator car safety device, reasonable in design, with easy to manufacture, cost is low, easy to use, security
High the advantages of.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is control principle block schematic illustration of the invention.
In figure：1- elevators, 2- cars, the air bags of 3- first, the air bags of 4- second, 5- stall sensors, 6- controls
Device processed.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, a kind of elevator car safety device that the present invention is provided, including elevator 1, the elevator
Car 2 moving up and down is provided with well 1, the ground of the elevator 1 is provided with outside the first air bag 3, the car 2
Side bottom, which is provided with the second air bag 4, the car 2, is additionally provided with stall sensor 5, and first air bag 3, second is pacified
Full air bag 4 and stall sensor 5 are electrically connected to controller 6.
The controller 6 is PLC.
The air bag 4 of first air bag 3 and second triggering can the sky full of the elevator 1 of relevant position after opening
Between.
Operation principle：During 2 normal operation of car in elevator 1, the first air bag 3 and the second air bag 4 are in
Closed mode；When the car 2 in elevator 1 breaks down, and the situation for causing stall to be fallen occurs, set on the lift car 2
The stall sensor 5 put detects stall signal, and the signal is sent to controller 6, and then rapid control triggering opens the to controller 6
One air bag 3 and the second air bag 4, the first air bag 3 are full of the outer lower portion space of car 2, the second air bag 4
Inner bottom surface space full of elevator 1, after car 2 falls, will cause the first air bag 3 and the second air bag 4 to be collided,
The impulsive force that car 2 is subject to thus has been buffered to greatest extent, effectively prevent the occupant in car 2 by serious injury,
Improve the security of the operation of lift car 2.
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art,
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacing, within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc. should be included in this
Within the protection domain of invention.
