The invention discloses a supporting frame device for a crane, and belongs to the technical field of crane supporting frames, the supporting frame device comprises a supporting seat, the interior of the supporting seat is hollow, a pair of symmetrical moving grooves are formed in the two side faces of the supporting seat, moving blocks are slidably connected into the moving grooves, a through hole is formed in one side face of each moving block, and a rotating shaft is rotatably connected into the through hole; a pair of symmetrical rotating rods are fixedly connected to the surface of the rotating shaft, a connecting pipe is fixedly connected between the two rotating rods, a round pipe is fixedly connected between the two rotating rods, a connecting rod is fixedly connected to the surface of the round pipe, a supporting block is fixedly connected to the bottom end of the connecting rod, and a pulley is arranged at the bottom end of the supporting block. By arranging the motor, the rotating shaft, the rotating rod, the connecting rod, the supporting block and the hydraulic oil cylinder, the motor drives the rotating shaft to rotate, the rotating rod rotates to drive the connecting rod and the supporting block to move, the supporting block makes contact with the ground and then is matched with the hydraulic oil cylinder, the supporting base is jacked up, and therefore the crane at the top end of the supporting base is supported.

    本发明公开了一种起重机用支撑车架装置,属于起重机支撑车架技术领域,包括支撑座,支撑座内为空心状,支撑座的两侧面开设有一对对称的两个移动槽,移动槽内滑动连接有移动块,移动块的一侧面开设有通孔,通孔内转动连接有转轴,转轴的表面固定连接有一对对称的转杆,两个转杆之间固定连接有连接管,两个转杆之间固定连接有圆管,圆管的表面固定连接有连杆,连杆的底端固定连接有支撑块,支撑块的底端设置有滑轮。本发明通过设置有电机、转轴、转杆、连杆、支撑块和液压油缸,电机带动转轴转动,使得转杆转动带动连杆和支撑块移动,并使得支撑块与地面接触,然后与液压油缸配合,将支撑座顶起,从而对支撑座顶端的起重机进行支撑。
