Problems solved by technology

Ropes and cables (hereinafter referred to as long objects) of high-lift elevators installed in high-rise buildings are easily affected even by slight building swaying. Depending on the position of the car, long objects resonate with building swaying. Contact or hook with the equipment in the hoistway, thus causing damage to the elevator

Embodiment approach 1

[0027] Hereinafter, the elevator control device in Embodiment 1 of the present invention will be described with reference to the drawings. Regarding the reference numerals in the drawings, A indicates the structure of the first machine, and B indicates the structure of the second machine. The structures of A and B are the same, so the description of B will be omitted.

[0028] figure 1 An overall configuration diagram of an elevator according to Embodiment 1 of the present invention (only the first elevator) is shown. The elevator car 2A moving in the elevator hoistway 1A is connected to the counterweight 3A by the main rope 4A (long object), and the elevator car 2A and the elevator car 2A are formed by rotating the traction machine 5A around which the main rope 4A is wound. The structure in which the counterweight 3A is raised and lowered in the form of a hanging bottle. 6A-1 to 6A-3 represent the halls of each floor, and the rotation of the hoisting machine 5A can be cont...

Abstract

The elevator control device has: a resonance position distribution unit (17), which selects an elevator that is not in service among a plurality of elevators, and makes the elevator stand by at the resonance position; long object swing detection devices (10A, 10B), which detect The long object swing of the predetermined level of the elevator standing by; the operation control unit (13A, 13B), which is controlled to make the elevator standing by at the resonance position travel to the A non-resonant position; and a control operation control unit (16), which is controlled to receive the detection result of the long object swing from the operation control unit (13A, 13B) when the long object swing detection device (10A, 10B) detects the long object swing , and travel the elevators other than the elevator that detected the swing of the long object to a non-resonant position.

Description

technical field [0001] The present invention relates to an elevator control device for controlling operation by a long object swing detection device installed in a hoistway when a building where an elevator is installed vibrates due to strong wind or long-period earthquake. Background technique [0002] Even when the acceleration of the earth's surface is about several gal, when the vibration of a building caused by a long-period earthquake is close to the natural period of a high-rise building, the building resonates and the vibration lasts for several minutes or more. In addition, high-rise buildings sway slowly with a natural cycle during strong winds. Therefore, for example, high-rise buildings continue to sway for a long time from the approach of a typhoon until it passes through. Ropes and cables (hereinafter referred to as long objects) of high-lift elevators installed in high-rise buildings are easily affected even by slight building swaying. Depending on the positio...
