Lifting device with anti-falling function
The invention discloses a lifting device with the anti-falling function. The lifting device comprises a frame, a lifting tray and an anti-falling mechanism, wherein the lifting tray is mounted on oneside of the frame in a sliding mode, the anti-falling mechanism is mounted on the bottom side of the lifting tray, a top plate is mounted on the top side of the frame, and a first speed reducer is mounted at the middle of the top side of the top plate; and the output end of the first speed reducer is connected with the output end of a first servo motor, transmission shafts are horizontally mountedat the output end of the first speed reducer, shaft seats are mounted at two ends of the top side of the top plate and connected with the transmission shafts, chain wheels are mounted at the two endsof the transmission shafts, and chains are mounted on the top sides of the chain wheels in a meshed mode. When the lifting tray is lifted to a set height, a second servo motor of the anti-falling mechanism works, a second speed reducer adjusts the speed to drive a rotating base to rotate by 90 degrees, at the moment, connecting rotating rods drive an inserting rod to be screwed into limiting grooves of steel bases, forced fixing of the inserting rod and the steel bases is achieved, and the lifting tray is limited and fixed.
本发明公开了一种具有防坠落功能的升降装置，包括框架、升降托盘和防坠落机构，所述框架一侧滑动安装有升降托盘，所述升降托盘底侧安装有防坠落机构，所述框架顶侧安装有顶板，所述顶板顶侧中部安装有第一减速机，所述第一减速机输出端和第一伺服电机输出端连接，所述第一减速机输出端水平安装有传动轴，所述顶板顶侧两端均安装有轴座，且轴座与传动轴连接，所述传动轴两端均安装有链轮，所述链轮顶侧啮合安装有链条；本发明通过升降托盘升降到既定高度时，防坠落机构的第二伺服电机工作，第二减速机调速带动转座旋转90°，此时连接转杆带动插杆旋入钢座的限位槽内，实现插杆和钢座的强制固定，对升降托盘进行限位固定。
