Sliding type anti-pinch escalator

Abstract

The invention discloses a sliding type anti-pinch escalator and aims to overcome the defects that an existing escalator anti-pinch trigger structure is an irreversible trigger structure, is limited by the strength requirement of an escalator and is slow to trigger. The sliding type anti-pinch escalator comprises an apron outer plate close to a step and an apron supporting plate far away from the step, wherein a sliding notch is formed in the apron outer plate; an anti-pinch plate is arranged on the sliding notch; a guide groove corresponding to the anti-pinch plate is formed in the apron supporting plate; the anti-pinch plate is slidably connected onto the apron supporting plate through the guide groove; and the anti-pinch plate is elastically connected with a safety switch. Compared with traditional deformation triggering, the triggering force of the anti-pinch plate at each position is the same, so that the triggering area is enlarged, the triggering is more sensitive, the personal injury is reduced, the anti-pinch plate is simple to reset after being triggered, the damage to the escalator is avoided, and the restarting work of the escalator can be quickly recovered.

Description

technical field [0001] The present invention relates to an escalator protective device, more specifically, it relates to a sliding type anti-pinch escalator. Background technique [0002] Escalators save the consumption of people moving between floors and improve people's lives. With the increasing application of escalators, people pay more and more attention to safety. There is a certain gap between the skirt board and the steps of the escalator. When the escalator is working normally, foreign objects may enter the gap between the skirt board and the steps, resulting in dangerous situations. Most of the current escalator anti-pinch devices use the deformation of the apron plate installed between the steps to trigger the safety switch, and the national standard has strict requirements on the deformation of the apron plate after being stressed. Therefore, there is a problem of insensitive triggering, which is likely to cause safety problems ACCIDENT. [0003] Therefore, th...

There is a certain gap between the skirt board and the steps of the escalator. When the escalator is working normally, foreign matter may enter the gap between the skirt board and the steps, resulting in a dangerous situation.

Most of the current escalator anti-pinch devices use the deformation of the apron plate installed between the steps to trigger the safety switch, and the national standard has strict requirements on the deformation of the apron plate after being stressed. Therefore, there is a problem of insensitive triggering, which is likely to cause safety problems ACCIDENT
