Auxiliary mechanical hand for bridge large-scale reinforcement cage construction

CUI FENGKUN

An auxiliary mechanical hand for bridge large-scale reinforcement cage construction comprises an outer sleeve upper connecting rod, an outer sleeve lower connecting rod, an inner sleeve upper connecting rod, an inner sleeve lower connecting rod, a telescopic buckle and a mechanical hand. A fixing frame is fixed to the upper end of the outer sleeve upper connecting rod, and the lower end of the outer sleeve upper connecting rod is arranged in the outer sleeve lower connecting rod and can slide up and down along the outer sleeve lower connecting rod. The inner sleeve upper connecting rod is arranged in the outer sleeve upper connecting rod, a circular inner sleeve knob used for manually rotating to drive the inner sleeve upper connecting rod to rotate is fixed to the upper end of the inner sleeve upper connecting rod, and the inner sleeve upper connecting rod penetrates an open hole in the fixing frame to be connected with the inner sleeve knob. The inner sleeve knob is arranged at the upper end of the fixing frame. The left-right rotation of an inner sleeve controls the opening motion of the mechanical hand, a tooth-shaped magnet is arranged in the mechanical hand, clamping is firmer under the attraction effect of the tooth-shaped magnet, the labor intensity of workers is reduced, and the working efficiency is improved.

本发明的一种用于桥梁大型钢筋笼施工的辅助机械手，包括外套筒上连接杆、外套筒下连接杆、内套筒上连接杆、内套筒下连接杆、伸缩卡扣和机械手，外套筒上连接杆的上端固定有固定框架，外套筒上连接杆的下端设置于外套筒下连接杆内且能沿外套筒下连接杆上下滑动；内套筒上连接杆设置于外套筒上连接杆的内部，内套筒上连接杆的上端固定有用于手动旋转带动内套筒上连接杆转动用的圆形的内套筒旋钮，内套筒上连接杆穿过固定框架上的开孔与内套筒旋钮相连接，内套筒旋钮设置于固定框架的上端。内套筒的左右转动控制机械手的张开运动，机械手内部设置齿状磁铁，在齿状磁铁吸附作用下夹持的更加牢固，减小工人的强度，提高工作效益。
