It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] Embodiment 1,

[0018] refer to Figure 1 and Figure 2 The utility model provides an automatic tamping control system for a dynamic tamping machine, comprising a controller 1, a winch control handle 2, a mode conversion switch 3, a winch encoder 4, a touch display 5, a winch brake solenoid valve 6, a winch clutch proportional solenoid valve 7, a winch lifting proportional solenoid valve 8 and a winch lowering proportional solenoid valve 9. The winch control handle 2 is connected to the controller 1 by communication, the mode conversion switch 3 is connected to the digital input port of the controller 1, the winch encoder 4 is installed on the encoder driven gear 10, the encoder driven gear 10 is meshed with the encoder driving gear 11, the encoder driving gear 11 is installed on the dynamic tamping machine drum, the winch encoder 4, the touch display 5 are connected to the controller 1 by communication, the winch brake solenoid valve 6 is connected to the digital output port of the controller 1, the winch clutch proportional solenoid valve 7, the winch lifting proportional solenoid valve 8, and the winch lowering proportional solenoid valve 9 are respectively connected to the PWM output port of the controller 1.

[0019] The controller 1 is a 32-bit high-performance, high-protection-level safety controller, and the control program in the controller is written using existing technical means; the hoisting control handle 2 is connected to the controller 1 by CAN bus communication, which is safe and reliable; the mode conversion switch 3 is a gear switch; the hoisting encoder 4 is connected to the controller 1 by CAN bus communication, and the hoisting encoder 4 is a multi-turn absolute value encoder, which is used to measure the number of hoisting lowering or lifting circles, and calculate the lifting or lowering distance of the wire rope according to the number of circles and the parameters of the drum and wire rope; the touch screen display 5 is a high-protection, high-resolution, full-color touch screen display; the hoisting brake solenoid valve 6 is a switch solenoid valve. The hoisting clutch proportional solenoid valve 7, the hoisting lifting proportional solenoid valve 8 and the hoisting lowering proportional solenoid valve 9 are proportional electromagnets.

[0020] When the utility model is used to manually control the dynamic compaction machine, the following steps are included:

[0021] 1. Set the parameters such as the upper limit height value, lower limit height value, deceleration stop time value, lifting speed, lowering speed, and number of tamping times of the rammer on the touch display 5;

[0022] 2. Set the mode conversion switch 3 to the manual mode gear, operate the winch control handle 2 forward or backward, and the handle signal is transmitted to the controller 1. The controller 1 controls the winch brake solenoid valve 6 to be energized according to the lifting or lowering command, and the winch lifting proportional solenoid valve 8 or the winch lowering proportional solenoid valve 9 is energized to realize the lifting and lowering action of the winch, and then adjust the lifting height of the rammer. When the rammer touches the ground, the lifting height is calibrated to 0.

[0023] When the utility model is used to automatically control the dynamic compaction machine, the following steps are included:

[0024] 1. The mode conversion switch 3 is set to the automatic mode gear, and the "cycle start" button on the touch display 5 interface is long pressed to start the function. At this time, the controller 1 controls the winch brake solenoid valve 6 to be energized, and controls the winch lifting proportional solenoid valve 8 according to the set current to realize the lifting of the winch rammer;

[0025] 2. When the lifting height reaches the set height, the system alarms, the winch brake solenoid valve 6 loses power, the winch lifting proportional solenoid valve 8 loses power, the winch clutch proportional solenoid valve 7 controls the port to output the maximum set current, the clutch disengages, and the rammer drives the winch to fall freely;

[0026] 3. When falling, when the current weight height is less than the set lower limit, the tamping action ends, and the controller 1 controls the current of the winch clutch proportional solenoid valve 7 to gradually decrease to 0mA according to the set deceleration time, the clutch is engaged, and the pressure gradually reaches the maximum value until the winch and wire rope decelerate and stop, and the deceleration process ends. At this point, a tamping hammer lowering tamping cycle ends;

[0027] 4. The system repeats the above steps 1-3 to implement a cyclic tamping action until the number of tamping times reaches the number set on the touch display 5, and the cyclic function exits.
