Abstract

The invention relates to the technical field of fire-fighting elevators and discloses a cat ladder device for a fire-fighting elevator. A safety window is formed in the roof of an elevator car of the elevator. A storage type cat ladder is fixed to one side of the safety window. The cat ladder can be extended into the elevator car downwards and inwards and can be stored on the upper portion of the safety window. The cat ladder can also be extended towards a shaft outwards. The cat ladder device can extend and contract, the cat ladder device can be folded on the roof of the elevator car in the normal state, the area in the elevator car cannot be occupied, and the appearance of the elevator car is not influenced. In rescue, firstly steps are extended into the elevator car for rescue in the elevator car, the steps are extended into the shaft after staff leaves the elevator car for the shaft rescue, the cat ladder is arranged on the roof of the elevator, and two purposes are achieved through one ladder.

Description

technical field [0001] The invention relates to the technical field of fire elevators, in particular to a ladder climbing device for fire elevators. Background technique [0002] According to GB26465-2001 "Safety Code for Manufacture and Installation of Fire Elevators", clause 5.4.1 requires that "a car safety window should be set on the top of the car, and its size should be at least 0.5m×0.7m"; clause 5.4.4 requires "Should provide a method that can fully open the car safety window from the fire elevator car." Existing fire elevators are equipped with car, ladder, car roof safety window, car roof and other components for fire rescue. Since the space inside the elevator car is limited, if the ladder is directly placed inside the car and hung on the car wall, This not only affects the overall aesthetics, but also takes up space for standing people. [0003] Existing ladders are fixed on the inner side wall or front side wall of the car. The fire ladder involved in the Chin...
