Elevator apparatus

Abstract

The invention discloses an elevator device, which can prevent or reduce the ear plugging feeling and the earache without a special device and without greatly reducing the running efficiency. The elevator device is provided with a control device (10) that responds to the elevator cage calling (7a) and the elevator hall calling (8a) to perform the logging-on of the target floor, and outputs the running order to a driving device (5) so as to accelerate the elevator cage (1), or to run the elevator cage at a given speed, or decelerate the elevator cage, so as to finally reach the target floor. The control device (10) calculates the lifting distance from the starting floor to the target floor; when the lifting distance exceeds a specified value, the acceleration or the deceleration is determined in the way that the acceleration or the deceleration of the elevator cage (1) is determined to be smaller if the lifting distance is longer, so as to reduce the atmosphere variation rate inside theelevator cage, and to prevent or reduce the ear plugging feeling and the earache of the passengers, thereby facilitate the operation of the elevator cage at a rating speed, and preventing the reduction of the running efficiency.

Description

technical field [0001] The present invention relates to an elevator device with a higher rated speed installed in a high-rise building with a higher floor, in particular to an elevator device capable of preventing or alleviating the feeling of ear plugging and ear pain caused by the change of air pressure when the elevator car is running. elevator installation. Background technique [0002] Generally speaking, in high-rise buildings, it is more inclined to install elevators with higher rated speeds. For example, the rated speed of some elevators can reach 750 m / min, and even 1000 m / min. When riding this kind of high-speed elevator installed in a high-rise building, due to the difference in air pressure between the upper floor and the lower floor, the change in air pressure will affect the eardrum of the ear, and almost all passengers will feel earplugs. That is to say, when the human ear changes relative to the external air pressure, the internal pressure of the external ea...

Problems solved by technology

[0004] However, in the above-mentioned scheme of continuously changing the air pressure in the elevator car with a certain amount of change, special devices such as exhaust fans and suction fans need to be provided, so the weight of the elevator car will increase, and the drive device will be large. , and increase the cost

In the proposal of installing an earache prevention switch in the elevator car, measures can only be taken after the ear feels an abnormality, so the prevention effect on earplug sensation and earache sensation is low.

However, in the scheme of setting the driving speed lower when the driving distance is longer, there are problems such as the longer time to reach the destination layer, which reduces the operating efficiency, especially the longer the driving distance. The more obvious it is, the more anxious it will be to the passengers
