Abstract: The invention discloses a multifunctional rigid-flexible operation engineering rescue accessory. The accessory comprises a frame, two working hydraulic cylinders, eight gripping device connecting rods, two gripping claws, a flexible cleaning device base, a movable guide sleeve, a guide slider, a guide slider rail, a rotary guide sleeve, eight sweepers brush, a functional hydraulic cylinder, and a working hydraulic motor. A gravel clearing function and a stone grabbing function are achieved by using one accessory, and different from a traditional engineering accessory integrating rigid movement, the accessory has the advantage of integrating rigid operation and flexible operation. A rigid grabbing system and a flexible sweeping system are arranged outside the frame and in the cavity of the frame respectively, so as to realize function conversion; through pushing out and retracting of a piston of the functional hydraulic cylinder, the sweeping brushes can be pushed out of the cavity to work and retract to be hidden so that the grabbing function and the sweeping function can be rapidly converted; and moreover, working requirements in various working states are met, and motion interference is avoided.
