Summary:The utility model provides a pile-pulling mechanism, and further provides pile-pulling machinery and lifting machinery with the pile-pulling mechanism. The pile-pulling mechanism comprises a support, a lifting tool, an inhaul cable and a pulley block. The pulley block comprises a fixed pulley placed on the support and a movable pulley placed on the lifting tool; the inhaul cable alternately winds through a groove of the fixed pulley and a groove of the movable pulley, one end of the inhaul cable is fixed opposite to the support, and the other end of the inhaul cable is used for puling the lifting tool to move towards the direction of the fixed pulley in the pile-pulling process. The pile-pulling mechanism is simple in structure and relatively low in manufacturing cost; the pile-pulling mechanism matched with a hoisting mechanism or with lifting machinery can conduct pile-pulling operations; and expensive pile machinery does not need buying or renting, and special water-flushing equipment or special excavating
