If there is a beam 501 in the building between the cars 401a and 401b of the elevator B, there is a wall of the building, and there is no elevator system adjacent to the failed elevator that can be a rescue elevator. In such a case, there was a problem that the passenger inside the failed elevator could not be rescued. In the above-mentioned elevator emergency rescue device, two elevators are placed side by side for rescue work.
In the case of two elevators having a vertical relationship in a single hoistway like the elevator apparatus disclosed in Japanese Patent No. 220075, the other rescue elevator is stopped near the upper part or the lower part of one faulty elevator. If the control must be controlled and the control is not accurate, the rescue elevator stops and collides with the faulty elevator, causing a secondary disaster, or because it is in the same hoistway. On the contrary, there was also a problem that the distance required for rescue could not be secured in the same hoistway, and rescue work was hindered.

The present invention has been made in order to solve the above problems, and in the case where a beam or a wall exists between two elevators installed in parallel because of the structure of the building. Even if there are two elevators installed in parallel in the building, it is possible to quickly and reliably rescue the passengers trapped inside the failed elevator. The first purpose is to obtain a device. In addition, during an emergency of an elevator, it is possible to accurately approach and stop the rescue elevator car at a predetermined position on the top (or bottom) of one elevator car that has become inoperable by stopping in the same hoistway. The second purpose is to obtain a rescue device.

[Means for Solving the Problems] In the elevator emergency rescue device according to the present invention,
A first elevator car having a rescue port provided on the floor; a hoistway through which the first elevator car moves up and down; and a first elevator car located below the first elevator car in the hoistway, and When the elevator car of the first elevator car moves up and down independently and one of the first elevator car and the second elevator car of which the rescue opening is provided in the ceiling part fails and stops, the other remains. Rescue operation control means for causing the elevator car of (1) to approach the defective elevator car.

[Action]

In the elevator emergency rescue device according to the present invention, when one elevator in the same hoistway fails, another elevator above or below the elevator accurately approaches or joins with the failed elevator, and the ceiling or floor of the elevator. Passengers inside the failed elevator are transferred to the rescue elevator in the upper part or in the lower part via the rescue exit provided in the.
