A Safe and Reliable Escalator

Abstract

The invention relates to the technical field of escalators, in particular to a safe and reliable escalator. The safe and reliable escalator comprises a handrail breast board, an apron board and a stair. An inner cover plate is arranged between the apron board and the handrail breast board. The apron board comprises an upper apron board body and a lower apron board body. The lower apron board body is arranged at the side edge of the stair, and an apron board safety protection device is connected to the lower apron board body. The upper apron board body comprises an arc-shaped anti-clamping part. The arc-shaped anti-clamping part is arranged on the stair and covers the side edge of the stair. The side edge of the stair is provided with a groove formed in the longitudinal direction. The arc-shaped anti-clamping part is provided with a blocking part stretching into the groove. The outer side of the blocking part is provided with a protection strip. According to the safe and reliable escalator, an object can be effectively prevented from entering a gap between the apron board and the stair by arranging the arc-shaped anti-clamping part, and the size of a clearance between the arc-shaped anti-clamping part and the end surface of the stair is adaptively adjusted along with the change of the seasonal temperature, so that the clearance is kept in a reasonable and safe range, and the situation that the apron board is stuck due to the fact that the apron board makes contact with the stair is prevented.

Description

technical field [0001] The invention relates to the technical field of escalators, in particular to a safe and reliable escalator. Background technique [0002] Escalators are usually equipped in public places such as shopping malls, hotels, cultural and entertainment venues, subways, stations, and airports. On the one hand, escalators bring people the enjoyment of going up and down, but the safety accidents caused by escalators There is also no lack of hearing and seeing; for example, due to the irreversible gap between the apron board and the steps, which is only of varying degrees, damage to passengers' shoes, trousers and even children's fingers caused by this gap. Accidents are not uncommon. [0003] As far as the reason is concerned, when the passenger is in the ascending running area of ​​the escalator, the shoe rubs against the apron plate, and the outer edge of the shoe is subjected to a vertically downward friction component, and when this force is large enough, t...

Problems solved by technology

For example: an escalator described in the Chinese utility model with application number 201410369980.2 includes an apron plate and a step, and also includes an apron plate protection mechanism. One side in the length direction of the steps corresponds to the steps; the side of the mounting seat facing the length direction of the steps is provided with two mutually horizontally arranged slots, the slots are respectively slot one and slot two, the The first slot is on the top, and the second slot is down; the first slot is embedded with an elastic flat plate; the second slot is embedded with a brush, and the brush extends towards the direction of the step and there is a gap between the apron plate and the step. Gap shielding; the length direction plane dimensions of the elastic flat plate and the brush are the same, and the elastic flat plate covers the brush; the brush is set in the shape of a bent one end, and the bent end faces the step direction , the disadvantage is that the anti-pinch effect of the escalator is poor
