The invention provides a reinforcement cage autonomous manufacturing, transferring and installing device and method, and relates to the field of reinforcement cage manufacturing and installing.The device comprises an integrated crawler-type carrier provided with a
material storage bin, the
material storage bin comprises a main reinforcement
storage area and a
stirrup storage area, and a sorting mechanical arm is arranged in the
material storage bin; the hydraulic erecting bearing platform comprises a bearing platform frame with the
tail end hinged to the integrated crawler-type carrier and a hydraulic
system used for driving the bearing platform frame to be overturned to the vertical state. Each
gantry crane robot comprises a rectangular-
ambulatory-plane frame installed on the bearing platform frame in a sliding mode, a first universal mechanical arm, a second universal mechanical arm and supporting claws, the first universal mechanical arm and the second universal mechanical arm are arranged on the inner walls of the two sides of the rectangular-
ambulatory-plane frame and used for grabbing the main reinforcements and the stirrups, the supporting claws are arranged on the other two side walls of the rectangular-
ambulatory-plane frame and used for fixing the main reinforcements, and a
welding gun is arranged on the first universal mechanical arm; a hydraulic
pulley used for driving the hoop reinforcement cage to rotate and advance in the concentric-square-shaped frame is arranged in the concentric-square-shaped frame. The manufacturing, transferring and mounting efficiency of the reinforcement cage can be improved.
