Technical Field

The invention relates to the field of elevators, in particular to a vertical elevator protection device with high safety and a vertical elevator.

Background

At present, elevators are commonly used in urban high-rise buildings, but potential hazards exist in the aspect of safety protection in the existing elevator design. The elevator is an automatic product combining electrical control and mechanical transmission, and faults such as electrical part aging, control failure, mechanical abrasion failure and the like can naturally exist. One of elevator faults is that an elevator door without a car is opened, and people can enter the elevator shaft to accidentally fall under the conditions of inattention, poor sight and the like; in addition, in order to facilitate the up-and-down movement of the elevator car in the elevator shaft, no equipment for blocking the movement of the elevator car is arranged in the elevator shaft, and the following elevator accidents can occur:

when the elevator fails, the elevator door is automatically opened or is lighter and easy to open, and people are not aware of the fact that the elevator door is easy to fall into the elevator shaft, so that casualties are caused;

when the elevator fails, maintenance personnel cannot know which floor the elevator car stops at, and when the elevator car needs to be checked one by one, the elevator door is opened, accidents of falling into the elevator shaft can occur, and casualties are caused;

thirdly, when people forcibly open the elevator door, people can fall into the elevator shaft; for example: the drunk people forcibly open the elevator door, and the drunk people can fall into the elevator shaft to cause casualties.

Accordingly, the present inventors have made extensive studies to solve the above problems and have made the present invention.
