The invention discloses an elevator speed limiting device, comprising a speed regulator rope which is arranged in a ring shape through a speed regulator pulley in a lifting channel and is connected with an elevator car for lifting; the driving bevel gear is assembled on a horizontal shaft of the speed regulator pulley; the driven bevel gear is meshed with the driving bevel gear; the centrifugal speed regulator is connected with the driven bevel gear through a vertical shaft; and a car stop switch that stops driving the car when the ascending speed or the descending speed of the car detected by the centrifugal governor exceeds a predetermined value, and that stops driving the car when the ascending speed or the descending speed of the car detected by the centrifugal governor exceeds the predetermined value. The centrifugal speed regulator is provided with one variable speed regulation part up and down operation section which controls the ascending speed of the elevator car and controls the descending speed of the elevator car, and the descending limiting speed of the elevator car is set to be lower than the ascending limiting speed of the elevator car. According to the invention, the effects of stabilization and noise reduction are achieved while the space is saved.

    本发明公开了一种电梯限速装置,包括:调速器绳索,在升降通道内通过调速器滑轮设置成环状并与所述电梯轿厢连接而进行升降;一个驱动锥齿轮,装配在所述调速器滑轮的水平轴上;一个从动锥齿轮,与所述驱动锥齿轮啮合;一个离心式调速器,通过铅垂轴而与所述从动锥齿轮连接;轿厢停止开关,在由该离心式调速器检测出的轿厢的上升速度或者下降速度超出了规定值时,轿厢停止开关停止对所述轿厢的驱动,所述离心式调速器具有1个可变调速部分上、下行运行区段控制所述电梯轿厢的上升速度和控制所述电梯轿厢的下降速度,并且使得所述电梯轿厢的下降限制速度设定成低于其上升限制速度。本发明在节省空间的同时,达到稳定、降噪的功效。
