Anti-collision safety device for elevator landing door

Abstract

The invention discloses an anti-collision safety device for an elevator landing door. The device comprises an upper ridge bottom plate (1); a guide rail (2) is arranged at the bottom part of the upper ridge bottom plate (1); a groove (3) is formed in the bottom part of the guide rail (2); a limiting plate (4) is arranged at the right side of the guide rail (2); the guide rail (2) is connected with a hanging plate (6) through a roller (5); a horizontal extending part (7) is arranged at the bottom part of the hanging plate (6); a tenon (8) vertical to the horizontal extending part (7) is arranged on the horizontal extending part (7); a waist-shaped hole (9) is formed in the hanging plate (6); the hanging plate (6) is connected with the roller (5) through the waist-shaped hole (9) and a bolt (10). According to the device, the limiting plate, the tenon, the groove and the horizontal extending part are arranged, so that the hanging plate can be prevented from largely deviating or falling down due to collision; the position of the roller can be adjusted through the waist-shaped hole and the bolt, which facilitates the mounting of the hanging plate; the device can prevent the landing door from falling down due to collision as well as preventing the roller from staggering, and also has the advantages of being convenient to process, and convenient to mount.

Description

technical field [0001] The invention relates to an anti-collision safety device for an elevator landing door, in particular to an anti-collision safety device acting on the top of an elevator landing door. Background technique [0002] In the existing elevator, the elevator landing door is installed on the upper sill floor of the elevator through the hanging plate and the roller; when the landing door is opened or closed, the roller rolls on the guide rail of the upper sill floor, so that the landing door can move along the upper sill floor . When a passenger accidentally hits the landing door, the rollers are likely to break away from the guide rails, causing the landing door to fall, causing safety accidents. Therefore, there are the problems that landing doors are easy to fall and rollers are easy to misplace when they are hit in the existing elevators. Contents of the invention [0003] The object of the present invention is to provide an elevator hall door anti-coll...

AI Technical Summary

Problems solved by technology

When a passenger hits the landing door accidentally, the rollers are easily detached from the guide rail, causing the landing door to fall, causing a safety accident

Therefore, in the existing elevator, there are problems that the landing door is easy to fall and the rollers are easy to dislocate when being hit.
