Description

Elevator door safety device

Technical Field

The utility model relates to the technical field of elevators, in particular to an elevator door safety device.

Background

Vertical elevators are multi-story building passengers or cargo, commonly used vehicles. During the use of the elevator door, the sliding block of the lower foot of the door moves back and forth in the sliding groove of the sill, the sliding block can be worn and the fixing bolt is loosened after long-term running, when serious, the elevator door is unstable and even falls off the groove, so that people and goods in the elevator car fall out of the elevator car, and accidents occur.

Elevator doors are an important mechanism for preventing passengers and goods from falling and shearing during use. The existing elevator car door can not run along the sill chute due to the fact that the car door sliding block is worn out and invalid in long-term running or the fixing bolt is loosened and falls off, at this time, the car door can lose the anti-falling and anti-shearing functions, passengers and cargoes in the car can not be guaranteed safely, when serious, the car door is pushed outwards by the external force of the passengers and cargoes, the foots of the car door can move outwards in a limited way, if the elevator runs up and down at this time, the car door can collide with the hoistway wall nearby the elevator door and parts mounted on the wall, and all elevator door devices of multiple layers can possibly run into the car, so that accidents such as casualties and the like are caused.

Disclosure of Invention

The utility model aims to solve the technical problem of providing the elevator door safety device capable of stopping an elevator in time when the situation that the elevator door cannot run along the sill chute due to long-term running abrasion failure of the elevator door sliding block or loosening and falling of the fixing bolt occurs.

An elevator door safety device comprises a safety mechanism, a door opening and closing mechanism, a car door and a car.

As a further improvement of the above technical scheme:

the utility model provides an elevator door safety device, elevator door bottom passes through the slider and installs in the spout of below sill, safety device includes spacing support, spacing support installs on the sill and is located lobby one side for the elevator door, installs safety inspection switch on the spacing support.

The limit bracket comprises an installation table, a support frame and a bearing table, wherein the installation table is tightly connected with the sill through bolts, the support frame is used for connecting the installation table and the bearing table up and down, and a safety detection switch is arranged on the bearing table.

The safety detection switch comprises a feeler lever and a sensor, and the feeler lever is connected with the sensor.

The sliding block comprises a limit sliding block and a limit rod; the limiting slide block is connected with the limiting rod and is arranged in the sliding groove of the sill.

The elevator door bottom is provided with the mounting, is equipped with fixing bolt and is connected gag lever post and mounting.

Compared with the prior art, the utility model has the advantages that:

when the situation that the elevator car door sliding block fails in long-term running abrasion or the fixing bolt loosens and falls off to enable the elevator car door to run along the sill sliding groove cannot occur, the elevator can be timely and accurately judged to the current situation through the safety switch, and the elevator can be timely stopped. Has the advantage of quick and accurate judgment.
