The invention discloses a mechanical arm for grabbing a large-tonnage prefabricated structural block on the ground and an assembling trolley, the assembling trolley comprises the mechanical arm and a trolley chassis, the mechanical arm comprises a gripper assembly, a slewing bearing arranged on the trolley chassis and an arm frame assembly, and the two ends of the arm frame assembly are hinged to the gripper assembly and the slewing bearing respectively; the arm frame assembly comprises a telescopic arm frame and a rotary arm frame, the gripper assembly comprises a rotary mechanism, a first translation mechanism, a second translation mechanism and a clamping mechanism which are sequentially connected, the moving directions of the two translation mechanisms are perpendicular to each other, and the clamping mechanism comprises a grabbing rod, a clamping jaw and a clamping oil cylinder. The grabbing rod is arranged on the second translation mechanism and used for being connected with a tool preassembled on the prefabricated structural block. The clamping jaw is movably arranged on the grabbing rod and provided with an abutting piece. The clamping jaw is driven by the clamping oil cylinder to get close to the prefabricated structural block, so that the abutting piece is tightly attached to the surface of the prefabricated structural block. The structure has the multi-angle installation freedom degree, the positioning requirement of the large-tonnage prefabricated part is met, and the operation is safer and more efficient.
