High-rise fire escape device

Abstract

The invention discloses a high-rise fire escape device. The high-rise fire escape device comprises a frame, a first escape ladder, limiting grooves, limiting blocks, a second escape ladder and a clamping mechanism; the frame is assembled on the front side of a building main body window; one end of the first escape ladder is mounted at the bottom end of the inner side of the frame through a pin shaft; two limiting grooves are provided, and are symmetrically formed in the front and back sides of the inner wall of the first escape ladder; and one side of each limiting block is embedded in an inner cavity of the corresponding limiting groove. The device prevents the defect of unfolding the escape ladders only by a top layer, guarantees self-operation by users to open the escape ladders for escape in fire on any layer, is provided with slow tables for downward transfer layer by layer to provide buffer to the users and to effectively prevent the users from directly falling to the ground without releasing from the hands, saves the escape time for the users, improves the equipment safety, and is high in practicability and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of escape equipment, in particular to a high-rise fire escape device. Background technique [0002] Fire escape and refuge equipment is the auxiliary escape equipment used by people in distress to escape from the fire in the event of a fire. Fire escape and refuge equipment includes escape slow descent device, escape ladder, emergency escape device, escape rope, fire filter self-rescue respirator, etc. Correct use of fire escape and refuge equipment can reduce casualties in the event of a fire; [0003] At present, as a kind of high-rise fire-fighting and escape equipment, escape ladders usually need to operate the ladder opening button on the top floor to use gravity to open all escape ladders floor by floor. To operate, and if a fire occurs in the middle and high floors, it still needs to be opened from the top floor layer by layer, which takes a long time, so there are certain limitations and accidents i...

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-rise fire escape device to solve the problem that the existing escape ladder proposed in the above background technology needs to be operated by the top floor to open the ladder opening button, and at the same time, the escape ladder still needs to be opened by the top floor layer by layer when a fire occurs in the middle and high floors. Use technical questions with certain limitations
