The invention belongs to the technical field of AGV forklifts, and particularly relates to a cantilever telescopic lifting mechanism and an AGV forklift. According to the cantilever telescopic lifting mechanism, the fork arm assemblies directly extend into the fork holes of the pallet shaped like the Chinese character'tian 'in a suspended mode to carry materials, and collision loss between the fork arm assemblies and the pallet shaped like the Chinese character'tian' is well avoided; a guide rail groove and a locking mechanism are arranged in the containing groove to restrain a first guide wheel and a second guide wheel on the rear side of the fork arm assembly so as to eliminate a revolute pair, so that the fork arm assembly only keeps a planar kinematic pair and is prevented from tilting and swinging forwards and backwards due to instability, and therefore it is guaranteed that the fork arm assembly stretches out or resets in a suspended mode; when the fork arm assembly is initially lifted in the extending state, a gravity sensor used for detecting the downward pressure of the first guide wheel is arranged at the front end of the guide rail groove, and lifting limitation on the fork arm assembly is unlocked only when the downward pressure of the first guide wheel is reduced to a preset value; and the situation of lifting blockage caused by forward inclination of the gravity center of the fork arm assembly in the initial lifting stage is also avoided, and the use reliability is good.
本发明属于AGV叉车技术领域,具体涉及悬臂伸缩升降机构及AGV叉车。悬臂伸缩升降机构通过将叉臂组件设置为以悬空方式直接伸入田字形栈板的叉孔中进行物料搬运,较好地避免叉臂组件与田字形栈板之间发生碰撞损耗,而且容纳槽内配置有导轨槽和锁定机构对叉臂组件后侧的第一导轮和第二导轮进行约束以消去转动副,使叉臂组件仅保留平面运动副,避免叉臂组件失稳前后倾摆,从而保证叉臂组件以悬空方式进行伸出或复位,以及叉臂组件在伸出状态初始举升时,导轨槽前端配置有用于第一导轮的下压力进行检测的重力感应器,使第一导轮的下压力下降至预设值时才解锁对叉臂组件的举升限制,也避免叉臂组件在初始举升阶段由于重心前倾导致举升卡顿的情况,使用可靠性好。
