The invention belongs to the field of lifting transportation, and particularly relates to a flexible limiting device and lifting equipment. The flexible limiting device comprises a fixing frame, a lead screw nut adjusting mechanism is installed on the fixing frame, a limiting nut is installed on a lead screw of the lead screw nut adjusting mechanism and can move in the axial direction of the lead screw along with rotation of the lead screw, and a speed change switch and a limiting switch which are used for ascending limiting and descending limiting are installed on the fixing frame. The limiting nut is in transmission connection with a switch triggering mechanism, and the triggering stroke of the variable-speed switch corresponding to the switch triggering mechanism is smaller than that of the limiting switch corresponding to the switch triggering mechanism. The flexible limiting device is higher in limiting precision, lower in installation requirement, simple and compact in overall structure and better in lifting stroke adjustability, and flexible adjustment and buffering limiting of lifting operation are achieved.
本发明属于起重运输领域,特别是涉及一种柔性限位装置及提升设备。柔性限位装置包括固定架,固定架上装有丝杠螺母调节机构,丝杠螺母调节机构的丝杠上装有限位螺母并可随丝杠转动沿其轴向移动,固定架上安装有用于上升限位以及下降限位的变速开关与限位开关,限位螺母传动连接有开关触发机构,并且变速开关对应开关触发机构的触发行程小于限位开关对应开关触发机构的触发行程。本柔性限位装置限位精度更高,安装要求更低,整体结构简单紧凑,升降行程的调整性更好,实现了升降作业的柔性调整与缓冲限位。
