Safety device of passenger conveying apparatus

Abstract

Disclosed is a safety device of passenger conveying equipment capable of preventing accidents caused by the emergency stop of the passenger conveying equipment. The passenger conveying equipment is disposed between two floors of building slantwise; a triangular space is formed between a building level sunshade part or an external component of the passenger conveying equipment adjacent to the building level sunshade part and a movable handrail moving in a cross direction relative to the building level sunshade part or the external component of the passenger conveying equipment adjacent to the building level sunshade part; an approximately triangular protection plate is fixed in the triangular space; the safety device has an emergency displaying switch and a emergency stop switch; while an external force is applied on the approximately triangular protection plate to caused the protection to move a first distance in horizontal direction, the emergency displaying switch is switched on; while an external force is applied on the approximately triangular protection plate to caused the protection to move a second distance which is larger than the first one, the emergency stop switch is switched on.

Description

technical field [0001] The present invention relates to a safety device for passenger conveying equipment capable of preventing an object from being caught in a horizontal ceiling portion formed in a building or an external member adjacent to the horizontal ceiling portion of a passenger conveying apparatus and moving in a crossing direction In the triangular space between the armrests. Background technique [0002] When passengers get on the passenger conveyor having a triangular space formed between the horizontal ceiling portion of the building or the outer member adjacent to the horizontal ceiling portion of the passenger conveyor and the moving handrails moving in the cross direction from the lower floor When moving to the upper floor, when the object protrudes beyond the railing beyond the moving handrail and moves in this state, it will be caught by the horizontal ceiling part of the building or the adjacent part of the horizontal ceiling part of the passenger conveyo...

Problems solved by technology

[0005] In the above prior art, when an external force above a certain magnitude is applied to the roughly triangular protective plate, causing the roughly triangular protective plate to move over a certain distance toward the direction of the external force, the detection switch is turned on, e.g. emergency stop of passenger conveyors

However, from the viewpoint of ensuring safety, it is unavoidable to control the emergency stop of the passenger conveying equipment, but when the passenger conveying equipment stops suddenly, other passengers may fall due to the sudden stop of the passenger conveying equipment, causing accidents. accident happened
