The working process of the invention is as follows: the static pile press 1 hangs the pile 14 to the pile clamping device 12 through the crane or other cranes on the pile press 1, the pile 14 moves to the through hole 121 of the pile clamping device 12 under the working 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 sliding rail 153 to move the pile 14 to the position right above the pile 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 travel sensor 4 also records the relative displacement distance of the pile clamping device 12 and the pile 14 when the pile is in descending, the pressure sensor 2 always transmits signals to the processor 5 for processing, the processor 5 transmits the pressure signals to the display screen 6 in the cab 13 in real time, when the pressure value is larger than or equal to the set value, the processor 5 outputs corresponding reminding information to the operator and inputs the pressure value to the memory for pile to store the corresponding reminding information, the pile height information is convenient for the storage of the depth adjustment information, and the depth adjustment information is stored in the memory. The operator stops the continued downward movement of the pile clamp 12 by observing a corresponding alert signal in the display screen 6 and releases the pile clamp 12 from the pile 14 and moves the pile clamp 12 out of the pile 14 to end the pile pressing operation.
The telescopic end of the first hydraulic cylinder 110 has a maximum extension position and a minimum extension position, when the telescopic end drives the pile clamp 12 to move downwards to the maximum extension position, but the pressure value of the pressure sensor 2 does not reach the preset value, the pile clamp 12 releases the pile 14, the pile clamp 12 clamps the pile 14 after the telescopic end moves upwards to the minimum extension position, and the telescopic end moves downwards until the pressure value of the pressure sensor 2 reaches or exceeds the preset value.
The pull-wire type displacement sensor 3 only records and superimposes the distance the wire 31 is pulled down. Specifically, when the pile clamp 12 releases the pile 14, the roller 41 of the travel sensor 4 is disengaged from the side surface of the pile 14, and at this time, the travel sensor 4 inputs a corresponding signal to the processor 5, and the processor 5 does not process the signal input by the pull-wire displacement sensor 3. When the pile clamp 12 clamps the pile 14, after the roller 41 of the stroke sensor 4 contacts with the side surface of the pile 14, the stroke sensor 4 inputs a corresponding signal processor 5 to the processor 5 to process and record the signal input by the stay wire type displacement sensor 3.
In summary, the embodiment of the invention provides a piling system and a piling method, which are implemented by arranging a processing module and a display module; the hydraulic driving mechanism 11 is provided with a pressure monitoring module which is used for monitoring the pressure value of the hydraulic driving mechanism 11 when in operation and transmitting the pressure value to the processor 5 for processing, the pressure signal processed by the processor 5 is transmitted to the display module for display, and when an operator acquires the 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 to continuously drive the pile clamp 12 to move downwards; the pile depth measuring module obtains the moving distance of the pile 14 in the vertical direction (namely the distance that the pile 14 is pressed into the ground) and transmits the signal to the processor 5 for processing, and finally, the signal is displayed through the display module; the operator is not required to be observed and informed by other manual work; effectively reduce the cost of labor, improved the efficiency of pressing the stake.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
