A kind of lift escape device
Technical field
The utility model relates to a kind of lift appliance, particularly a kind of lift escape device.
Background technology
Along with increasing rapidly of skyscraper, elevator becomes indispensable vehicle.At present, conventional lift does not all possess fire-fighting function, forbids that people take lift escape when presence of fire.Because be subject to temperatures involved when it, or the stoppage in transit that has a power failure, or ignition, will bring disaster to the people who takes elevator, even seize their life.Existing elevator does not all arrange self-rescue escape device, must wait for outside rescue.The wait of long period, will inevitably greatly reduce people's existence probability.So how, in the situation that having a power failure, fast-escape from the elevator of sealing, is an important problem.
Utility model content
The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, and a kind of manual operations, fireballing lift escape device are provided.
The utility model is achieved by the following technical programs: a kind of lift escape device, comprise escape window, manual pulley, connecting rod, dead bolt and attic ladder, described escape window is arranged on the top of elevator cab, the middle part of escape window is provided with manual pulley that can positive and negative rotation, one end of described connecting rod is hinged in manual pulley, the other end of described connecting rod is provided with dead bolt, and described attic ladder is arranged on the side of escape window, can manually stretch.
In the time running into emergency situation and need to escape, need to be by electric power operation, manual pulley that can manual rotation escape window, manual pulley drivening rod, dead bolt are retracted, just can easily escape window be opened, then the attic ladder that manually stretches, escape from elevator cab from attic ladder rapidly.
The utlity model has simple and compact for structure, safe and reliable, do not need the advantages such as electric power operation, escape speed be fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: l-escape window, 2-manual pulley, 3-connecting rod, 4-dead bolt.
The specific embodiment
As shown in Figure 1, a kind of lift escape device, comprises escape window 1, manual pulley 2, connecting rod 3, dead bolt 4 and attic ladder.Described escape window 1 is circular, is arranged on the top of elevator cab, and escape window 1 is connected by hinges with elevator cab one place, can open and can close along hinges.
The middle part of escape window 1 is provided with manual pulley 2 that can positive and negative rotation, and one end of connecting rod 3 is hinged in manual pulley 2, and the other end of connecting rod 3 is provided with dead bolt 4, and described dead bolt 4 is inserted in the lockhole on elevator cab during in closed condition at escape window 1.In the time running into emergency situation and need to escape, need to be by electric power operation, manual pulley 2 that can manual rotation escape window 1, manual pulley 2 drivening rods 3, dead bolt 4 are retracted, and just can easily escape window 1 be opened.Described attic ladder is arranged on the side of escape window 1, can manually stretch.
The utlity model has simple and compact for structure, can effectively utilize the existing space of elevator car roof, more safe and reliable feature.
