The present invention discloses a frame structure with an umbrella-shaped carrying device, which belongs to the technical field of caterpillar cranes, and includes a main frame structure. An umbrella-shaped carrying device is welded or assembled at the top of the main frame structure, and the left and right sides of the main frame structure are rotatably connected to frame swing legs in the front and back directions, respectively; the frame swing legs are connected to square holes on a caterpillar rack; a connection part is disposed below a front end of each frame swing leg; a frame swing leg fixing hinge pin and a limiting hinge pin are respectively provided at an inner end and an outer end on the connection part; and a first fixing hole and a second fixing hole in cooperative use with the frame swing leg fixing hinge pin and the limiting hinge pin are respectively formed at a lower bottom surface in the square hole. The frame structure with an umbrella-shaped carrying device provided in the present invention can enable the frame to be adapted to the high carrying capability for a pivoting support with a large diameter and a high lifting performance requirement when a caterpillar chassis is in a wide track state, and also meet, when retracted to a small size of an extremely narrow track, the requirements that the transmission width of the caterpillar chassis does not exceed a limitation and the frame does not interfere with the caterpillar rack.
