Problems solved by technology

[0002] For example, when the vibration caused by an earthquake starts to occur, if you rush into the fast running area of ​​the area without the elevator door, you will be outside the door area when the vibration increases and the emergency stop occurs, so there is a problem that it will take time to rescue.

Embodiment Construction

[0038] Embodiments of the present invention are described below with reference to the drawings.

[0039] figure 1 It is a system configuration diagram showing the overall configuration of the present invention. exist figure 1 Among them, 1 is an elevator car, and there are a motor 2 for driving the elevator, and a counterweight 3 provided at a position facing the car, and they are respectively connected via pulleys 4 and slings 5 ​​. Moreover, the encoder 6 is attached to the motor 2, and the position detection of an elevator is performed by the pulse of the encoder 6 generated according to the rotation of the motor 2. In addition, there is a governor pulley 7 that rotates in conjunction with the elevator car, and a governor encoder 8 is attached to the governor pulley 7, and the governor encoder 8 that is generated according to the rotation of the governor pulley 7 is used. The pulse can also detect the position of the elevator. In addition, shielding plates 9a, 9b, 9c ar...

Abstract

The present invention provides an elevator. If the elevator emergently stops at a fast driving region, before fast driving again, the elevator is required to drive with a low speed until reaching a gate region for confirming position data. There is a problem that a lot of time is required before rescuing passengers under the low speed driving. A control apparatus elevates a car with a first speed after emergently stopping the car, a safety controller uses a speed regulator encoder to create position information of the car, and the control apparatus determines the position of the car on basis of the elevator position transmitted by the safety controller and elevates the car with a second speed faster than the first speed when the car is not in the gate region.

Description

technical field [0001] The present invention relates to elevators. Background technique [0002] For example, when the vibration caused by an earthquake starts to rush into the fast running area of ​​the area without the elevator door, the elevator will be out of the door area when the vibration increases and the emergency stop occurs, so there is a problem that it will take time to rescue. [0003] For example, in Patent Document 1, the following method is considered: in a building with a fast-traveling zone, when the elevator senses a given vibration while running in the fast-traveling zone, it is judged whether to travel above or below the fast-traveling zone , to run. [0004] Patent Document 1: JP Laid-open No. 2011-131996 [0005] In the aforementioned prior art, in order to prevent an emergency stop itself in the fast-traveling zone, means are proposed for driving out of the fast-moving zone. However, if the elevator temporarily stops suddenly in the fast running z...
