Abstract
The invention discloses a ventilation device for an elevator car, which comprises a ventilating port arranged on the roof of the elevator car, a fixed frame, a guide frame arranged on the fixed frame, wherein, the fixed frame is arranged on the roof of the elevator car at the ventilating port; the guide frame is provided with a cover or an emergency-ventilation action piece which goes through the ventilation port. The device of the invention has the advantages of increasing effective ventilation area in the elevator car in case of power failure, remarkably improving the ventilation situation in the elevator car, reducing the oxygen deficiency rate of trapped people with significant effect.
Description
Technical field
The present invention relates to the drafting apparatus in a kind of lift car.
Background technology
General passenger elevator, its car ventilation system is typically provided with breather port, and adopts electrical equipments such as axial-flow fan or air-conditioning to strengthen fanning effect, and the payload space of breather port is usually slightly larger than 1% of car payload space.When elevator is in power down mode,, cause the air flow property in the car to reduce because draft equipment is out of service and the breather port area is less.At this moment if oppressive situation in the car just may cause being had difficulty in breathing because of anoxic by oppressive, particularly trapped personnel more for a long time, situation is more serious.
Summary of the invention
The purpose of this invention is to provide a kind of elevator cage ventilating device, can when elevator has a power failure, open, increase the draught area of car.
Technical solution of the present invention is: a kind of elevator cage ventilating device, it comprises the vent window, the fixed frame that are arranged on the car top board, is located at the guide frame on the fixed frame, wherein fixed frame is arranged on the car top board at vent window place, and guide frame is provided with the emergency ventilation action piece that hides or connect vent window.
When elevator has a power failure, can push the emergency ventilation action piece of covering open at car top board vent window place, increase the available ventilation area of car, improve the airiness situation in the car, reduce the probability that anoxic appears in trapped personnel.
As a kind of prioritization scheme, described emergency ventilation action piece is made up of the top board and cover plate, the elastic telescopic spare that are set in parallel on the described guide frame, wherein top board is respectively equipped with the identical electromagnetic force arrangement of energising back polarity with cover plate inside, top board is fixed on described guide frame top, cover plate can slide up and down along described guide frame, and the two ends of elastic telescopic spare connect top board lower surface and cover plate upper surface respectively.When elevator normally moves, under the electromagnetic force effect, cover plate hides at the vent window place, when dead electricity, electromagnetic force disappears, and cover plate upwards slides under the elastic force effect, connect vent window, automatically connect vent window in the time of can realizing having a power failure, effectively improve the airiness in the car, improving increases the reliability that ventilates.
Outside described guide frame, be provided with grille guard, can effectively protect drafting apparatus, prevent that the top junk from entering car by vent window.
Described vent window is arranged on four jiaos of car top board or on the middle part, can effectively utilize
Advantage of the present invention is: can increase the available ventilation area in the car when having a power failure, significantly improve the airiness situation in the car, reduce the probability that anoxic appears in trapped personnel, effect is remarkable.

The specific embodiment
Embodiment:
Consult Fig. 1, vent window 8 is arranged on the car top board 6, can be arranged on respectively on four angles of car top board 6, can not take the space for maintenance on sedan-chair top like this, also can be arranged on the car top board 6 at bottom place of sedan-chair head piece space that like this can better utilization sedan-chair top.
Consult Fig. 2, a kind of elevator cage ventilating device, it comprises the vent window 8 that is arranged on the car top board 6, fixed frame 5, be located at the guide frame 4 on the fixed frame 5, wherein vent window 8 is positioned on the angle of car top board 6, fixed frame 5 is arranged on the car top board 6 at vent window 8 places, be arranged with top board 1 and cover plate 2 on the guide frame 4 in parallel, top board 1 is respectively equipped with the identical electromagnetic force arrangement (not shown) of energising back polarity with cover plate 2 inside, top board 1 is fixed on the top of described guide frame 4, cover plate 2 can slide up and down along described guide frame 4, can hide vent window 8 fully in the time of downwards, between the upper surface of the lower surface of top board 1 and cover plate 2, be provided with elastic telescopic spare 3.
When elevator normally moves, electromagnetic force arrangement energising in top board 1 and the cover plate 2 produces magnetic field, because polarity is identical, produce repulsive force mutually, because top board 1 is fixed on the top of guide frame 4, therefore cover plate 2 moves downward to being fitted in fully on the car top board 6 along guide frame 4, has hidden vent window 8 this moment, and elastic telescopic spare 3 is stretched simultaneously.
During the elevator dead electricity, electromagnetic force arrangement dead electricity in top board 1 and the cover plate 2, magnetic field disappears, cover plate 2 is at the elastic force effect lower edge of elastic telescopic spare 3 guide frame 4 upward movements, when elastic force and gravitational equilibrium till, at this moment, cover plate 2 leaves car top board 6, vent window 8 connects, and cab interior connects with extraneous, has increased draught area.
Consult Fig. 3,, be provided with grille guard 7, can prevent that the top from falling thing and entering in the car from vent window 8 in the periphery of guide frame 4 in order to protect this drafting apparatus.
Above-listed detailed description is at the specifying of one of the present invention possible embodiments, and this embodiment is not in order to limiting claim of the present invention, and the equivalence that all the present invention of disengaging do is implemented or change, all should be contained in the claim of this case.
