The invention relates to the technical field of mine hoisting equipment, and discloses a roller cage shoe during buffering. The roller cage shoe comprises a base, a swing arm is movably hinged to oneside of the upper end of the base, a buffer is movably hinged to the other side of the upper end of the base, the upper end of the buffer is movably hinged to one end of the swing arm, a rotating shaft base is fixedly connected to the middle of the swing arm, a rotating shaft is movably connected with the interior of the rotating shaft base in a sleeving manner, two sets of bearings are fixedly installed on a side face of one end of the rotating shaft, two sets of hubs jointly form a hub assembly of the roller cage shoe, the hub assembly is fixed through bolts, parts are convenient to machine,the roller cage shoe is simple to assemble, grooves of one set of hub are aligned with convex teeth to be embedded, fastening is achieved through bolts, the shearing force during rotating buffering of the roller assembly can be improved, the two sets of hubs are evenly stressed, long-time stress of the bolts is avoided, the problem that the bolts in the roller cage shoe are prone to breakage is solved, and the service life of the roller cage shoe is prolonged.
本发明涉及矿井提升设备技术领域,且公开了一种缓冲时滚轮罐耳,包括底座,所述底座上端的一侧活动铰接有摆臂,所述底座上端的另一侧活动铰接有缓冲器,所述缓冲器的上端与摆臂的一端活动铰接,所述摆臂的中部固定连接有转轴座,所述转轴座的内部活动套接有转轴,所述转轴一端的侧面固定安装有两组轴承,由两组轮毂共同组成该滚轮罐耳的轮毂总成,并且通过螺栓固定,不仅零部件加工方便,而且组装简单,通过将一组轮毂的凹槽对准凸齿进行嵌入,再通过螺栓紧固,能够改善滚轮总成旋转缓冲时的剪切力,使其两组轮毂均匀受力,避免螺栓长时间受力,解决了容易出现滚轮罐耳内部螺栓断裂的问题,延迟了滚轮罐耳的使用寿命。
