Problems solved by technology

Therefore, when the tail cable shakes due to shaking of the building, etc., the tail cable is likely to collide with various equipment installed in the hoistway, which may cause equipment failure or disconnection of the tail cable.
Since the longer the length of the tail cable, the greater the swing of the tail cable, the above-mentioned problems are particularly likely to occur in elevators for high floors

Abstract

The invention provides a tail cord vibration damper and an elevator equipped with the tail cord vibration damper. Arrangement space of the elevator is not required to be expanded for the tail cord vibration damper, installation operation of the elevator cannot be difficult, and a tail cord can be actually inhibited from vibrating. One or more tail cord vibration dampers (3A) are installed on a wall surface of an elevating channel (2) or on a structure object (12) fixed on the wall surface of the elevating channel, the tail cord vibration dampers (3A) is provided with a maintaining frame body (23) and an open-close member (24) for the tail cord (8), and the open-close member (24) is arranged on the maintaining frame body (23), opens through a retracing portion (8a), moving along with elevating of an elevator cab (4),of the tail cord (8), and automatically locks the maintaining frame body (23) after the retracing portion (8a) passes through.

Description

technical field [0001] The invention relates to an elevator and a vibration damping device for a tail cable connected at one end to an elevator car. Background technique [0002] The elevator has: an elevator car arranged in the hoistway; a hoist that lifts the elevator car by pulling or releasing a wire rope connected at one end to the elevator car; an elevator control device that drives and controls the hoist; and a tail cable, The tail cable supplies power from the elevator control to the elevator car and exchanges signals between the elevator control and the elevator car. One end of the tail cable is connected to the elevator car, and the other end is connected to the relay box arranged in the middle of the height direction of the hoistway. [0003] The tail cable vibrates due to various reasons. For example, the tail cable vibrates when a building shakes due to an earthquake, wind, etc., or when an elevator car is driven or stopped. In the existing general elevator, t...
