The invention relates to the field of elevator safety, and discloses a hydraulic buffer device for a high-speed elevator, which comprises a plurality of guide rails vertically mounted on the inner wall of an elevator shaft, a pod capable of ascending and descending along the guide rails and buffer devices mounted at the tops and the bottoms of the guide rails, the two sets of guiding devices are installed on the upper portions and the lower portions of the guide rails respectively, dragging lines connected with a pod are installed on the two sets of guiding devices, the multiple multi-stage buffering oil cylinders are installed on the tops and the bottoms of the multiple guide rails, and the multi-stage buffering oil cylinders, the guiding devices and the circulating oil tank are sequentially connected. The hydraulic buffering device composed of the guider, the multi-stage buffering oil cylinder and the circulating oil tank is arranged, the running speed of the elevator is monitored through the guider, meanwhile, the fixed pulley aligned with the dragging line is matched with the dragging line to drive the guider to react, the multi-stage buffering oil cylinder can work in advance, and therefore the buffering effect of the buffering device on the high-speed elevator is guaranteed.
本发明涉及电梯安全领域,公开了一种高速电梯用液压缓冲装置,包括竖直安装在电梯井内壁上的若干根导轨、可沿导轨升降的吊舱和安装在导轨顶部与底部的缓冲装置,缓冲装置包括引导器、多级缓冲油缸和循环油箱,引导器有两组,两组引导器分别安装在导轨上部和下部,两组引导器上均安装有与吊舱连接的拖线,数个多级缓冲油缸安装在若干根导轨的顶部与底部,多级缓冲油缸、引导器和循环油箱依次连接。本发明通过设置引导器、多级缓冲油缸、循环油箱组成的液压缓冲装置,通过引导器来监测电梯运行的速度,同时配合与拖线对齐的定滑轮与拖线配合驱动引导器反应,使多级缓冲油缸能预先工作,从而保证缓冲装置对高速电梯的缓冲效果。
