The specific embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
The burst power outage appears in elevator and when causing the elevator malfunction event, the ventilation system of existing lift car will shut down, and will not have for a long time airiness in the lift car.More existing technology solve by equipment such as configuration double circuit power supply, power failure automatic leveling emergency facility, powerplant modules, but these need expensive investment.
The utility model designs a kind of easy device according to actual conditions and is installed on the car roof, realizes the emergency ventilation of lift car under power down mode with lower cost like this.
Referring to shown in Figure 1, the utility model is opened a breather port at elevator car top, covers the cover plate 10 that an area is slightly larger than breather port on breather port again.Cover plate 10 is connected with expansion link by peripheral electromagnet 80 and is connected control cover plate 10 is opened automatically.Particularly, connect movable telescopic bar 20 on the cover plate 10, expansion link 20 connects the first end of lever 30, and the second end of lever 30 is fixed on the fixed pivot 41.The middle part of lever 30 is provided with point of connection, lever 30 point of connection top is connected and fixed device 40 by coil tension spring 50, and the below then connects a connecting rod 60, and an armature 70 is fixed in the lower end of connecting rod 60, armature 70 can be adsorbed on the fixing electromagnet 80, and electromagnet 80 is comprised of iron core 81 and coil 82.Coil 82 is connected on the power supply 90.On the circuit between power supply 90 and the coil 82 voltage relay 91 is set, is used for guaranteeing circuit safety.
When elevator was in normal operating condition, power supply 90 and voltage relay 91 closures provided 110 volts of direct supplys, and power supply is to electromagnet 80, and electromagnet 80 is in "on" position, with armature 70 attract from it.Armature 70 tension linkage 60, truck dead lever 30 thus, and the steel plate of renovating that fixedly makes with it interlock of lever 30 is in closed condition.
