Footing missing preventing footboard installing structure for escalator

Abstract

The invention discloses a footing missing preventing footboard installing structure for an escalator. The footing missing preventing footboard installing structure is characterized by comprising a pit, a footboard, an installing mechanism and a safety detection mechanism; the installing mechanism comprises two groups of trusses which are arranged on the left-side inner wall and the right-side inner wall of the pit respectively, the back side of the top of each truss is provided with an upper angular part, and the inner side, facing the pit, of each upper angular part is provided with an inner-side opening; the back sides of the two ends of the bottom face of the footboard are each provided with a lower angular part, and the outer side, facing the pit, of each lower angular part is provided with an outer-side opening; the upper angular parts and the lower angular parts are matched with each other in a clamping manner, and the footboard is installed on the trusses through the upper angular parts and the lower angular parts in a clamping matching manner; the safety detection mechanism is installed on the front-side inner wall of the pit, and the bottom face of the footboard abuts against the safety detection mechanism. According to the footing missing preventing footboard installing structure for the escalator, the using safety of the footboard is improved, and potential safety hazards are reduced.

Description

Technical field [0001] The invention relates to an escalator, in particular to an anti-stepping pedal installation structure of the escalator. Background technique [0002] Escalators, also known as escalators, or automatic pedestrian elevators, escalators, and escalators, are fixed electric drive equipment with circular running steps that are used to tilt up or down to transport passengers. [0003] There are pedals on the upper and lower parts of the escalator, which are used to manually enter the escalator or leave a stepping place of the escalator. Among them, in the past few years, when a user stepped on the pedal when exiting the escalator, the pedal fell and the user was caught in the elevator, causing a safety accident. [0004] Although a safety switch is used at the bottom of the pedal, in the prior art, the protective switch device used uses the principle of lever, similar to the rocker structure, and the switch is often touched by the movable cover during use.

Problems solved by technology

Among them, in the past few years, when the user stepped on the pedal when getting out of the escalator, the pedal fell, and the user was involved in the elevator, causing a safety accident.

[0004] Although a safety switch is used at the bottom of the pedal, in the prior art, the protective switch device adopted is based on the principle of leverage, which is similar to a seesaw structure. During use, it is often encountered that the switch is held by the movable cover and cannot be moved. Due to the situation, the protection switch device does not play a role, the effect is not ideal, and there is a great potential safety hazard

At the same time, when the pedal is installed, it is directly covered on the bottom pit, without any limit measures, so the pedal is very easy to be lifted or dropped, and there is a particularly large safety hazard
