Problems solved by technology

Therefore, when the lead wire swings, the movement of the liquid etc. enclosed in the hollow tube is restricted by the air resistance inside the hollow tube.
In this way, if the movement of liquid etc. in the hollow tube is restricted, when the lead wire swings greatly due to the occurrence of an earthquake, etc., it is difficult to sufficiently damp the swing of the lead wire.

Abstract

The invention provides a leading wire vibration-proof structure capable of fully suppressing the large-amplitude sway of the leading wire due to earthquake or strong wind. A leading wire (3) is connected between an elevator car (2) and a fixation part of a lifting path on which the elevator car lifts and moves and suspend in way of forming an U shaped bending part (8). The fluid (5) is filled intoa flexible hollow tube (4) integrated with the leading wire (3) along the long rim direction of the leading wire (3) and the two ends of the flexible hollow tube (4) open. Thus the fluid (5) freely moves in the hollow tube (4) to generate the vibration damping function, thereby preventing the sway of the leading wire when the leading wire sways.

Description

technical field [0001] The present invention relates to a vibration-damping structure for damping vibrations of lead wires of elevators due to strong winds, shaking of buildings caused by earthquakes, and other factors. Background technique [0002] Lead wires connected between the elevator car and the fixing portion of the wall of the hoistway are suspended from the elevator car. The lead wires are composed of various cables such as power lines for supplying power to the elevator car and signal lines for transmitting and receiving various control signals between the elevator car and the control panel of the elevator. [0003] In addition, when a building equipped with an elevator is hit by a strong wind, or the building shakes due to an earthquake, especially a long-period seismic movement, the lead wire will swing greatly. In this case, the lead wire collides with the wall surface of the liftway, which may cause damage to other equipment or components, and cause the lead ...
