Problems solved by technology

[0008] However, the above-mentioned elevator device is not equipped with a device that can prevent the lower car from excessively rising in the hoistway, or the upper car from excessively descending in the hoistway, or the upper car and the lower car from approaching each other.
Therefore, if the control system fails and the car or the counterweight cannot be controlled, a direct collision will occur between the cars or the counterweight, causing damage to the car and the counterweight.

Abstract

An elevator device consists of multiple cages in a shaft. Each cage has independent drive device and brake device. The brake device is located between the cages and can be independently stopped when urgency occurs.

Description

technical field [0001] The present invention relates to an elevator device, in particular to a comfortable elevator device for a one shaft multicar elevator. Background technique [0002] At present, a kind of elevator device called single shaft multi car (one shaft multi car) is used especially widely in high-rise buildings. In this elevator system, a plurality of cars are arranged up and down inside the hoistway, and the cars are raised and lowered by means of a driving device independently driving each car. Using this elevator device, during periods of high frequency of use of elevators, such as off-duty hours, lunch breaks, etc., multiple cars can be raised and lowered while avoiding mutual conflicts, while only one car can be lifted during periods of low use frequency. Carriage moves. In this way, not only can the elevators run efficiently, but also the installation space and cost required for installing multiple elevator devices can be reduced.
