Embodiment Construction

[0044] Hereinafter, embodiments of the rope swing detection device according to the present invention will be described with reference to the accompanying drawings.

[0045]

[0046] figure 1 It is a front view of the inside of the hoistway 12 for accommodating the elevator 10 according to the first embodiment as seen from the side of the seat (not shown) ( figure 1 The area sensor 52 is not present in the elevator 10, and the elevator 10 has the area sensor 52 as a constituent element of the rope swing detection device. figure 2 This is a right side view of the elevator 10 .

[0047] like figure 1 and 2 As shown, the elevator 10 is a rope drive type elevator using a hoisting method as a driving method. The machine room 16 is provided in the part of the building 14 higher than the uppermost part of the hoistway 12 . The machine room 16 is provided with a traction machine 18 and a guide wheel 20 . A plurality of main ropes are wound around the sheave 22 and the guid...

Abstract

The invention provides a rope swing detection device capable of detecting the yaw of the rope in all directions without increasing the number of sensors. Its structure includes an area sensor (52), which is arranged on the car (26) And outside the lifting path of the counterweight (28), measure the direction and distance of the object existing in the horizontal plane containing its setting position relative to the setting position, and output the direction and distance as position information; the detection mechanism, which is output by the area sensor Position information, detect the position coordinates of the rope portion of one of the main rope portion (24A) of the suspension car (26) or the compensation rope portion (32A) hanging down from the car (26) in the horizontal plane; the calculation device, It calculates the vibration amplitude of the yaw on the horizontal plane when the rope part is yaw based on the position coordinates of the rope part detected by the detection mechanism.

Description

technical field [0001] The present invention relates to a rope swing detection device, in particular to a rope swing detection device for detecting the swing of a main rope or a compensation rope caused by shaking of a building in which an elevator is installed due to earthquakes or the like. Background technique [0002] In recent years, with the development of high-rise buildings, the swing of the main rope or the like caused by the shaking of the building due to earthquakes or strong winds has become a problem of rope drive elevators. [0003] In most rope drive elevators installed on high-rise buildings, a machine room is installed higher than the top of the car hoistway, and a traction machine that drives the car is installed in the machine room. A main rope is hung on the sheave constituting the traction machine, one end of the main rope is connected to the car, the other end is connected to the counterweight, and the car and the counterweight are respectively suspende...
