The invention provides a drilling grabbing device used for underground diaphragm wall construction and a winch, and relates to the technical field of engineering machines. The drilling grabbing devicecomprises a base plate, a grabbing bucket, driven gears, and two drilling and tunneling mechanisms, the grabbing bucket is rotatably connected with the base plate, the drilling and tunneling mechanisms are connected to the two ends of the base plate correspondingly, each drilling and tunneling mechanism comprises at least two impact drills, the number of the impact drills is the same with that ofthe driven gears, drill bits of the impact drills and the grabbing bucket are located on the same side of the base plate, a mounting hole is formed in the base plate, drill rods of the impact drillsare mounted in the mounting holes in a penetrating manner and are connected with the driven gears, the drilling and tunneling mechanisms are mounted on the two sides of the base plate face where the grabbing bucket is located, in the drilling process of the drilling and tunneling mechanisms, the grabbing bucket is assisted to impact a hard and dense formation, and the construction efficiency is improved.
