Problems solved by technology

[0009] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an anti-blocking and anti-derailment elevator landing door guide structure, which solves the problem of easy accumulation of dust and sundries in the chute of the lower sill of the existing elevator landing door. After cleaning, the sundries hinder the sliding of the slider, which leads to the problem that the elevator landing door cannot be opened and closed normally; it also solves the problem that when the existing elevator landing door is hit, the upper roller is easy to come off, which causes the elevator landing door to fall off.

Embodiment 1

[0034] Such as figure 1 , 3 , 5, the anti-blocking and anti-derailment elevator landing door guide structure includes the elevator landing door 11, and also includes an upper roller assembly and a lower sliding assembly.

[0035] The lower sliding assembly includes a sill 21 , a slider 22 , a connecting plate 23 and a brush 24 . The sill 21 is set on the ground of the elevator car 12, and there is a chute 211 for the slider 22 to pass through. The bottom of the chute 211 is provided with an ash discharge hole 2111, and the edges on both sides of the upper end of the chute 211 are respectively provided with ribs. 212 , the distance S between the two ribs 212 is smaller than the width V of the lower end of the slider. The cross-sectional shape of the slider 22 is an inverted "T" shape, its lower end is installed in the chute 211 of the sill 21, and its upper end is fixedly connected with the connecting plate 23 . The upper end of the connecting plate 23 is affixed to the low...

Embodiment 2

[0043] Such as figure 2 , 4 , 5, compared with embodiment 1, this embodiment differs only in the structure of the lower sliding assembly. In this embodiment: the lower sliding assembly includes sill 21, slider 22, connecting plate 23 and brush 24. The sill 21 is located on the floor of the elevator car 12, and is provided with a chute 211 for the passage of the slider 22. The bottom of the chute 211 is provided with an ash discharge hole 2111. Shaped hole B2112. The cross-sectional shape of the slider 22 is "L"-shaped, and a positioning plate 221 protruding horizontally is provided on one side of the lower end thereof. The lower end of the slider 22 is installed in the chute 211 of the sill 21, and the upper end is fixedly connected with the connecting plate 23. When the lower end of the slider 22 is installed in the chute 211 of the sill 21, its positioning plate 221 extends into the bar-shaped hole B2112. When the slider 22 moves in the chute 211 of the sill 21, its pos...

Abstract

The invention discloses an elevator landing door guide structure capable of preventing blockage and derailment. The elevator landing door guide structure comprises an elevator landing door, an upper roller assembly and a lower slide assembly, wherein the lower slide assembly comprises a sill, a slide block, a connecting plate and a brush; the upper roller assembly comprises a first mounting plate,a second mounting plate, an upper roller, an upper roller shaft, a lower roller, a lower roller shaft and an anti-separating assembly; the anti-separating assembly comprises a bolt and a nut; when the elevator landing door is opened and closed, the slide block is driven to move in a sill slide slot at the lower end, the second mounting plate drives the upper roller to roll in a first roller slotat the upper end, the second mounting plate drives the lower roller to roll in a second roller slot at the upper end, and the second mounting plate drives a bolt to move in a strip-shaped hole A at the upper end. The elevator landing door guide structure has the advantages that: when the elevator landing door is opened and closed, the brush automatically sweeps impurities in the sill slide slot, and the elevator landing door does not integrally drop as a result of dropping from the upper part.

Description

technical field [0001] The invention relates to the field of special equipment, in particular to an anti-blocking and anti-derailment elevator landing door guide structure. Background technique [0002] With the rapid development of the country's economy, elevators, as an indispensable means of transportation in people's lives and one of the representatives of horizontal economic prosperity, are also showing a surge in number. At present, the number of elevators in my country is already the first in the world. [0003] However, while elevators bring convenience to people, many safety accidents have also occurred, causing certain casualties. Among these accidents, the number of accidents caused by elevator landing doors is the most. The reason is that apart from the fact that the elevators have been in disrepair for a long time and the components are aging, the elevator landing doors accidentally fall off, causing people to fall, and more are due to kicking the elevator landi...
