System and method for filling floor holes of elevator landing

Abstract

The invention discloses a hole filling system for an elevator landing floor, which is used for an elevator with at most three floors. The elevator includes an elevator control system, a car, a hole on the second floor and a hole on the third floor. The car bottom cover plate, the second floor cover plate and the third floor cover plate matched with the first floor hole and the third floor hole, the bottom of the car is locked and fixed by the first normally closed electromagnetic opening and locking device, and the second floor hole Lock and fix the cover plate on the second floor through the second normally closed electromagnetic opening and locking device, and lock and fix the cover plate on the third floor through the third normally closed electromagnetic opening and locking device in the hole on the third floor; the elevator control system is respectively connected with the first normally closed type electromagnetic opening and locking device, the second normally closed electromagnetic opening and locking device and the third normally closed electromagnetic opening and locking device are electrically controlled and connected. The present invention effectively fills the floor hole in the projected area of ​​the car after the car leaves the landing, prevents the danger of people falling from the floor hole, and protects the safety of surrounding people.

Description

technical field [0001] The invention relates to the technical field of elevator machinery, in particular to a system and method for filling holes in floor slabs of elevator landings. Background technique [0002] At present, most elevators are elevators with shafts and elevator shafts. However, due to the relatively deep depth of the elevator shaft, once the elevator breaks down, the elevator door will open abnormally, which will easily cause people to fall into the elevator shaft, causing personal danger. And for the elevator without hoistway, the hole in the projection area of ​​the car on the landing floor is directly flush with the landing floor, and people tend to fall into the bottom landing floor when walking on the landing floor, causing personal danger. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present invention is to propose a system and method for filling holes in elevator landing floors.

Problems solved by technology

[0002] At present, most elevators are elevators with shafts and elevator shafts. However, due to the deep depth of the elevator shaft, once the elevator fails, the elevator door will open abnormally, which will easily cause people to fall into the elevator shaft, causing personal danger.

For elevators without wells, the holes in the projection area of ​​the car on the landing floor are directly flush with the landing floor, and people are prone to fall into the bottom landing floor when walking on the landing floor, causing personal danger
