The invention relates to a grab bucket special for pipeline-like objects. The grab bucket special for the pipeline-like objects comprises a mounting board. Four mounting holes are symmetrically formed in the mounting board along the center axis. The grab bucket is installed on an existing crane or hoist through the four mounting holes. Four inclined supporting rods are symmetrically welded to the two sides of the lower end of the mounting board. A double-lifting lug is welded to the tail end of each supporting rod. The four double-lifting lugs of the four supporting rods are connected with four single-lifting lugs respectively through hinge pins. The four single-lifting lugs are symmetrically welded to two opposite grabbing branch chains. Two lug bases are symmetrically welded to the lower end face of the mounting board. Two hydraulic cylinders are installed between the two lug bases through hinge pins. Telescopic rods of the two hydraulic cylinders are installed on two baffles respectively. The two baffles are welded to the two grabbing branch chains respectively. The grab bucket can achieve the function of rapidly carrying the pipeline-like objects and has the advantages of being easy and convenient to operate, high in working efficiency, wide in application range and the like.
