Integrated winch pile hammer, special winch and application of special winch

The invention provides an A type integrated winch pile hammer and a B type integrated winch pile hammer, each of which integrates a winch and a heavy hammer into a frame. A special winch provided by the invention is used for the A type integrated winch pile hammer; an existing winch is used for the B type integrated winch pile hammer. The special winch can achieve the preset maximum drop distance of the heavy hammer when a roller is rotated less than a circle, a baffle is fixedly arranged on the roller, and a limiting stopper is fixedly arranged on a base. Through the baffle, the limiting stopper has the effects of limiting, buffering and rebounding on the roller. Compared with an existing separated winch pile hammer, the A type integrated winch pile hammer has the advantage of small steel wire rope loss and the like of the B type integrated winch pile hammer, and also has the advantages of being simpler in structure, easier to control, capable of better solving the problem of over discharging of a steel wire rope, and capable of enabling the hammering efficiency to be improved by more than 50%.
