The working process of the invention is as follows: the static pile press 1 lifts the pile 14 to the pile clamping device 12 through a crane or other cranes carried by the pile press 1, the pile 14 moves to the through hole 121 of the pile clamping device 12 under the operation of the crane, the second hydraulic cylinder 122 drives the telescopic rod to move and clamp the pile 14, the lifting mechanism 15 lifts the static pile press 1 and moves the static pile press 1 on the second slide rail 153 to move the pile 14 to be driven to be right above the position to be driven, the first hydraulic cylinder 110 drives the pile clamping device 12 to move downwards, the stay wire type displacement sensor 3 starts to record the moving distance of the steel wire 31 when the lower end of the pile 14 is contacted with the position to be driven, meanwhile, the stroke sensor 4 also records the relative displacement distance between the pile clamping device 12 and the pile 14 when the pile is descended, the pressure sensor 2 always transmits a signal to the processor 5 for processing, the processor 5 transmits the pressure signal to the display screen 6 in the cab 13 in real time for displaying, when the pressure value is greater than or equal to the set value, the processor 5 outputs corresponding reminding information to an operator, inputs the pressure value into the memory for storage, and inputs pile depth information and ground elevation information stored in the memory together so as to facilitate later-stage data check. The operator stops the pile gripper 12 from moving further downwards by observing the corresponding reminder signal in the display 6 and releases the pile gripper 12 from the pile 14, and moves the pile gripper 12 out of the pile 14 to finish the pile driving operation.
The telescopic end of the first hydraulic cylinder 110 has a maximum stretching position and a minimum stretching position, when the telescopic end drives the pile clamping device 12 to move downwards to the maximum stretching position, but the pressure value of the pressure sensor 2 does not reach a preset value, the pile clamping device 12 releases the pile 14, the pile clamping device 12 clamps the pile 14 after the telescopic end moves upwards to the minimum stretching position, and the telescopic end continues to move downwards until the pressure value of the pressure sensor 2 reaches or exceeds a set value.
The stay wire type displacement sensor 3 records and superimposes only the distance that the steel wire 31 is pulled downward. Specifically, when the pile gripper 12 releases the pile 14, the roller 41 of the stroke sensor 4 is disengaged from the side surface of the pile 14, and the stroke sensor 4 inputs a corresponding signal to the processor 5, and the processor 5 does not process the signal input by the stay wire type displacement sensor 3. After the roller 41 of the stroke sensor 4 contacts with the side surface of the pile 14 when the pile gripper 12 grips the pile 14, the stroke sensor 4 inputs a corresponding signal to the processor 5, and the processor 5 processes and records the signal input by the stay wire type displacement sensor 3.
In summary, the embodiment of the present invention provides a pile driving system and a pile driving method, which includes a processing module and a display module; a pressure monitoring module is arranged on the hydraulic driving mechanism 11 and used for monitoring the pressure value of the hydraulic driving mechanism 11 during working and transmitting the pressure value to the processor 5 for processing, a pressure signal processed by the processor 5 is transmitted to the display module for displaying, and when an operator acquires information that the pressure value of the hydraulic driving mechanism 11 reaches or exceeds a threshold value from the display module, the hydraulic driving mechanism 11 can be stopped from continuously driving the pile clamping device 12 to move downwards; the pile depth measuring module acquires the moving distance of the pile 14 in the vertical direction (namely the distance of the pile 14 pressed into the ground), transmits the signal to the processor 5 for processing, and finally displays the signal through the display module; no other manual observation is needed and an operator is informed; effectively reduce the cost of labor, improved pile pressing efficiency.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
