Problems solved by technology
[0002] Pile drivers are commonly used construction machinery in construction projects. Pile drivers can be divided into drop hammer pile drivers, spiral blade pile excavators, diesel hammer pile drivers, vibratory hammer pile drivers, etc. Drop hammer pile drivers use slippery winches to move The pile hammer weighing several tons is lifted to a certain height, and the tamping work of the pile foundation is completed by releasing the inertial kinetic energy obtained by the pile hammer. Compared with the spiral blade pile driver, diesel hammer pile driver, and vibratory hammer pile driver It has the advantages of simple structure, no environmental pollution, no construction waste, etc. Compared with the hydraulic winch system, the electric winch has the advantages of simple structure, convenient maintenance, and low cost. However, the existing pile driver still needs to rely on manpower. The labor intensity of workers is still high, the efficiency of piling operation is low, and the quality of piling needs to be improved. Based on this, it is still necessary to design a PLC-based drop hammer automatic pile driver control system
