The invention relates to a guide and buffer device used for a mine lifting container, in particular to a hydraulic buffer roller cage shoe. The hydraulic buffer roller cage shoe mainly consists of a roller, a bracket, a base and a buffer oil cylinder, wherein a dual-cavity structure is adopted in the buffer oil cylinder; a piston and an inner sleeve define a cavity A; a piston, a slide sleeve anda cylinder cover define a cavity B; and the cavity A communicates with the cavity B through a piston slot. While the roller is collided, the piston moves downwards to compress oil in the cavity A intothe cavity B, so that buffer is realized. The hydraulic buffer roller cage shoe is stable in buffer, is simple and compact in structure, is simple in manufacturing and is low in cost.
本发明涉及一种用于矿井提升容器的导向与缓冲装置,具体是一种液压缓冲滚轮罐耳,它主要由滚轮、支架、底座、缓冲油缸组成,缓冲油缸内采用双腔结构,由活塞与内套组成甲腔,活塞与滑套、缸盖组成乙腔,甲腔和乙腔之间由活塞槽连通,当滚轮受撞击时,活塞向下移动压缩甲腔油液进入乙腔,实现缓冲,本发明缓冲平稳,结构简单紧凑,制造简单,成本低。
