The traditional construction pile driver has high requirements for the construction personnel, is high in intensity, low in safety coefficient, complex in operation and difficult to guarantee the construction quality. In recent years, the manual punch pile driver is gradually improved to be automatic, the travel of the clutch cylinder and the brake cylinder of the punch pile driver is controlled through the addition of a pneumatic device, so as to realize the automatic control of the clutch and brake systems, and a sensor is added to detect whether the hammer jamming fault occurs.

[0130] In constructing the optimal hammer lifting height prediction BP neural network model, this invention uses vibration sensors to detect the vibration signal of the pile hammer, tension sensors to detect the tension signal of the wire rope, and velocity sensors to detect the perforation velocity signal as input signals. These three input signals are all lithology-related; when the lithology strength is high, the vibration signal and tension signal are large, and the perforation velocity is low; conversely, when the lithology strength is low, the vibration signal and tension signal are small, and the perforation velocity is high. The optimal hammer lifting height prediction BP neural network model is obtained by training with these input signals and the corresponding optimal hammer lifting height. This is equivalent to having a self-learning function, enabling the electric winch to always operate at the optimal hammer lifting height adapted to the current lithology, thereby improving pile driving efficiency, reducing labor intensity, and ensuring construction quality.
