The lift car rescue device can be used for the rescue from the external portion and self rescue from the internal portion under the emergent state, and is convenient to operate, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator car rescue device. Background technique [0002] As the height of buildings is getting higher and higher, the fire protection requirements for buildings are also getting higher and higher, and the market demand for fire elevators is also increasing. According to the requirements of the standard, the fire elevator car needs to have the functions of internal self-rescue of firefighters and external rescue of firefighters. Therefore, an emergency evacuation exit must be reserved on the car top of the fire elevator. In case the door opening mechanism of the elevator fails, the emergency evacuation exit can be used to escape. However, at present, there is no elevator car with an emergency exit that can facilitate rescue by opening the escape window from the outside, and can also be suitable for quickly opening the escape window from the inside in an emergency for self-r...
