no. 1 Embodiment approach ）

[0031] use Figure 1 to Figure 3 , the elevator rope swing suppression system according to the first embodiment of the present invention will be described.

[0032] Here, first, the elevator apparatus to which the elevator rope swing suppression system of this embodiment is applied is demonstrated. Such as figure 1 As shown, the elevator device 1 is provided with: a car 3, which can freely ascend and descend in the hoistway 2; a counterweight 5 for the car, which is connected to the car 3 via a main cable 4; and a traction machine (lifting drive part) 6 , which raises and lowers the car 3 and the counterweight 5 for the car via the main rope 4 . Among them, the hoisting machine 6 is disposed in a machine room 7 provided above the hoistway 2 . The main rope 4 is wound around a traction sheave (pulley) 8 and a guide sheave 9 connected to the hoisting machine 6 .

[0033] In such a configuration, the hoisting machine 6 rotationally drives the hoisting sheave 8, the main rope ...

no. 2 Embodiment approach ）

[0057] Next, according to Figure 4 to Figure 7 , an elevator rope swing suppression system according to a second embodiment of the present invention will be described.

[0058] exist Figure 4 to Figure 7 In the second embodiment shown, the main difference is that the swing suppressing member is moved in the front-rear direction by the winding motor, and the swing suppressing member moves rearward according to the positional relationship between the swing suppressing member and the car. Other composition and Figure 1 to Figure 3 The first embodiment shown is substantially the same. In addition, in Figure 4 to Figure 7 in, right with Figure 1 to Figure 3 The parts that are the same as those in the first embodiment shown are given the same reference numerals, and detailed descriptions thereof will be omitted.

[0059] Such as Figure 4 as well as Figure 5 As shown, the swing suppressing member 30 is moved in the front-rear direction by the winding motor (winding driv...

no. 3 Embodiment approach ）

[0081] Next, pass Figure 8 to Figure 10 , the elevator rope swing suppression system in the third embodiment of the present invention will be described.

[0082] exist Figure 8 to Figure 10 In the third embodiment shown, the main difference is that a plurality of swing restraining members are provided at positions different from each other in the lifting direction of the car, and the other configurations are the same as those of the third embodiment. Figure 4 to Figure 7 The second embodiment shown is substantially the same. In addition, in Figure 8 to Figure 10 in, right with Figure 4 to Figure 7 The parts that are the same as those in the second embodiment shown are given the same reference numerals, and detailed descriptions thereof will be omitted.

[0083] Such as Figure 8 As shown, a plurality of (here, two) swing suppressing members 30 ( 30 a , 30 b ) are provided at positions different from each other in the ascending and descending direction of the car 3 . ...

Abstract

The invention provides an elevator cable swing suppression system capable of effectively suppressing the swing of a main cable even when being installed at tall buildings. According to the embodiments of the invention, the elevator cable swing suppression system (20) comprises a swing suppression member (30) arranged in front of a main cable (4) to move freely along the anterior-to-posterior direction and suppress the swing of the main cable (4); and a swing suppression member moving mechanism (40) used for moving the swing suppression member (30). During the rising process of an elevator car (3), the swing suppression member moving mechanism (40) drives the swing suppression member (30) to move forwards. During the declining process of the elevator car (3), the swing suppression member moving mechanism (40) drives the swing suppression member (30) to move backwards.

Description

technical field [0001] Embodiments of the present invention relate to an elevator rope sway suppression system. Background technique [0002] In high-rise buildings with elevators, there is a phenomenon that the main rope, compensation chain, or counterweight rope of the elevator (hereinafter referred to as only the main rope, etc.) swings due to earthquakes or strong winds. Depending on the size of the swing, the main rope or the like may come into contact with each piece of equipment installed in the hoistway. In this case, there is a problem of damage to equipment that comes into contact with the main cable or the like. In addition, there is also a problem that the main cable or the like becomes entangled due to swinging. [0003] Conventionally, various proposals have been made to suppress the oscillation of the main cable or the like. For example, in Patent Document 1, a pair of rollers (rollers, rollers) pinches the main cable or the like to suppress swinging of the...
