Embodiment Construction

[0026] One embodiment of the elevator car of the present invention will be described in detail below using the drawings.

[0027] figure 1 The relationship between the frame of the elevator car of this embodiment and the active mass damper (hereinafter referred to as AMD) attached thereto is shown, (a) is a plan view, and (b) is a front view. The frame of the car is a conventional frame on which front doors, side panels and roof panels not shown in the figure are installed. That is, the above-mentioned front door, side panels, and roof panels are then attached to the frame to assemble the elevator car.

[0028] First, the structure of the car will be described. figure 1 Among them, the top view shape of the car floor 11 is a rectangle. A side ( figure 1 The two ends of the lower side in (a) are vertically provided with a pair of left and right longitudinal beams 12 . A frame material made of angle steel or the like is used for the pair of longitudinal beams, and is her...

Abstract

The present invention provides an elevator car capable of obtaining an effective vibration suppression effect by arranging a device for vibration suppression by an active mass damper at an appropriate position. It is characterized in that it has a car sheave (20) that is rotatably installed on a car sheave beam (19) installed on the car frame, and wraps around a rope for suspending the car. On the transmission path of the vibration generated by the sheave (20) to the above-mentioned car frame, a vibration that generates vibration in the opposite phase to the vibration generated from the car sheave (20) and suppresses vibration generated from the car sheave (20) is installed. The vibration of the active mass damper (23).

Description

technical field [0001] The invention relates to an elevator car with means for vibration damping by active mass dampers. Background technique [0002] At present, as a device for improving the ride comfort of the elevator car, as disclosed in Japanese Patent Application Laid-Open No. 4-3790, a damper is provided between the car frame and the hanging part of the rope, and the damper is realized by changing its attenuation characteristics. Device for damping vibrations in various situations. [0003] This damping device seals a piston-shaped moving body and oil in a hydraulic cylinder constituting a damper, and an electrically expandable member is provided in the hydraulic cylinder where the oil passes. Therefore, by energizing the part, the passing area of ​​the oil can be changed, the attenuation constant can be changed, and the vibration reduction of the car under various conditions can be realized. [0004] However, since the above-mentioned damping device uses an oil d...
