Abstract

An elevator hoistway door bending sill anti-drop device belongs to the technical field of elevators. The elevator car door comprises a hall car door bending sill, a hall car door anti-falling part and a door sliding block, wherein an anti-falling hook is arranged at the lower end of the hall car door anti-falling part, and is adaptive to an anti-falling opening arranged in a groove of the hall car door bending sill and enters the anti-falling opening to prevent the hall car door plate from falling off when the hall car door plate is impacted. The structure utilizes the structural deformation principle, solves the risk that the door plate of the elevator hoistway door breaks away from the sill due to collision, avoids the injury caused by falling, scraping, touching and shearing of personnel nearby the hoistway door, and has the advantages of low cost, simple structure, good stability and difficult damage.

Description

Hoistway door sill anti-drop device that bends

Technical Field

The utility model belongs to the technical field of elevators, and particularly relates to an elevator hall door bending sill anti-drop device.

Background

The hall door system is a passage for passengers to enter and exit the elevator car during the use process of the elevator. The more common hall door system is of a horizontal sliding structure, namely, a hall door plate is fixed in a slideway of a sill and horizontally slides along with the action of a door motor, so that the hall door system is opened and closed.

In the using process of the elevator, no matter stopping and running, the hall door is possible to be impacted; when the impact degree is lower, the strength of the hall door system can realize the anti-drop, and the danger is avoided, but when the impact degree is higher, the bearing range of the hall door system is exceeded, the hall door plate is impacted to be separated from the sill, and at the moment, people in the vicinity of the hall door and in the car have the danger of falling, scraping, touching and shearing at any time.

Disclosure of Invention

Aiming at the defects existing in the prior art, the utility model aims to provide an elevator hall door bending sill anti-drop device.

The utility model adopts the technical scheme that: the elevator hoistway door bending sill anti-drop device is technically characterized by comprising a hoistway door bending sill, a hoistway door anti-drop piece and a door sliding block, wherein the door sliding block is fixedly arranged at the lower part of a hoistway door plate through a connecting end and slides in a slideway of the hoistway door bending sill; the upper end of the elevator car door anti-drop piece is fixed on the elevator car door plate, the lower end of the elevator car door anti-drop piece is provided with an anti-drop hook, the anti-drop hook is adaptive to an anti-drop opening arranged in a bending sill groove of the elevator car door, and the elevator car door plate is prevented from falling off by entering the anti-drop opening when impacted by the elevator car door plate.

In the scheme, the waist-shaped hole is formed in the hall door anti-falling piece, and the hall door anti-falling piece is fixed on the hall door plate through the bolt of the waist-shaped hole.

The beneficial effects of the utility model are as follows: the elevator hoistway door bending sill anti-drop device comprises a hoistway door bending sill, a hoistway door anti-drop piece and a door sliding block, wherein an anti-drop hook is arranged at the lower end of the hoistway door anti-drop piece, and is adaptive to an anti-drop opening arranged in a hoistway door bending sill groove and enters an anti-drop opening to prevent a hoistway door plate from falling off when the hoistway door plate is impacted. The structure utilizes the structural deformation principle, solves the risk that the door plate of the elevator hoistway door breaks away from the sill due to collision, avoids the injury caused by falling, scraping, touching and shearing of personnel nearby the hoistway door, and has the advantages of low cost, simple structure, good stability and difficult damage.

Drawings

In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the drawings that are needed in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present utility model, and other drawings can be obtained according to these drawings without inventive effort for a person skilled in the art.

FIG. 1 is a schematic diagram of the overall structure of the present utility model;

fig. 2 is a schematic diagram of a hoistway door drop-off prevention apparatus of the present utility model;

the numbers in the figures are illustrated as follows: the elevator comprises a door plate of a 1-hall car door, a bending sill of a 2-hall car door, a 21 groove, a 22 rectangular opening, a 3-hall car door anti-falling piece and a 4-door sliding block.

Description of the embodiments

The foregoing objects, features, and advantages of the utility model will be more readily apparent from the following detailed description of the utility model when taken in conjunction with the accompanying drawings 1 and detailed description.

The elevator hoistway door that this embodiment adopted is bent sill anticreep device, including hoistway door plant 1, hoistway door is bent sill 2, hoistway door anticreep spare 3 and door slider 4, wherein hoistway door is bent sill 2 and is used the steel sheet to replace aluminum alloy material, and door slider 4 adopts non-metallic material. The door slide block 4 is fixedly arranged at the lower part of the hoistway door plank 1 through a connecting end, and the door slide block 4 slides in a groove 21 on the hoistway door bending sill and is used for limiting and positioning the motion of the hoistway door plank 1 in a slideway of the hoistway door bending sill 2. The hall door anti-drop member 3 of this embodiment is provided with a waist-shaped hole, and the bolt fixes the upper end of the hall door anti-drop member 3 on the hall door panel 1 through the waist-shaped hole. The lower end of the landing door anti-falling piece 3 is provided with an anti-falling hook, and the section of the groove 21 on the landing door bending sill 2 is basically of a straight structure, so that the anti-falling is difficult to realize, and therefore, the embodiment is also provided with a rectangular opening 22 matched with the anti-falling hook on the vertical section of the groove, so that the anti-falling hook can enter the anti-falling opening to prevent the landing door plate 1 from falling off when the landing door plate 1 is impacted.

The working principle of the elevator hall door bending sill anti-drop device in the embodiment is as follows:

first, the hall door drop-off preventing member 3 is fixed to the hall door panel 1. When the closed elevator door plate 1 encounters larger impact, the door sliding block 4 made of non-metal materials is firstly stressed to deform, meanwhile, the elevator door plate moves along the impact direction, the anti-falling hook at the lower end of the elevator door anti-falling piece 3 is driven to enter the rectangular opening 22 of the elevator door bending sill 2, the bottom of the elevator door plate 1 is limited by the sill groove 21 along with the continuous movement of the door plate, the elevator door plate 1 deforms, at the moment, the elevator door plate 1 is lifted upwards, the elevator door anti-falling piece 3 is driven to hook the rectangular opening 22 of the sill, the anti-falling is realized, and then the safety risk of the elevator and nearby personnel after the elevator door plate 1 is separated from the sill is solved.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
