Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery, and in particular to a dynamic compaction machine auxiliary operation control system and a control method. Background Art

[0002] A dynamic compactor is a kind of engineering machinery used for impact compaction of foundations, and is widely used in various foundation treatment construction operations. After the dynamic compactor lifts the rammer to a specified height, it releases the rammer to let it fall freely, and uses the high impact generated by the high drop of the rammer to compact the foundation.

[0003] At present, there are two construction modes in the construction process of dynamic tamping machines: non-decoupling and decoupling. Among them, the non-decoupling mode of dynamic tamping machines mostly uses a single-rate light hammer, which is mainly used for construction with small tamping energy. The tamping process mainly includes two actions: lifting the hammer and dropping the hammer. Since there is no hooking action in the non-decoupling mode, it is easier to achieve automatic control. At present, full automatic control has been achieved in the non-decoupling mode. The tamping process does not require manual intervention, and the process of operating the machine is relatively easy. The decoupling mode of dynamic tamping machines mostly uses a multi-rate heavy hammer, which is mainly used for construction with large tamping energy. The tamping process mainly includes three actions: lifting the hammer, dropping the hammer and hooking. In the decoupling mode, since the hooking action is difficult to achieve automatic control, the main action in the decoupling mode is still manually controlled, and the lifting hammer action is still achieved by manually pulling the joystick. The lifting hammer action accounts for the highest proportion of time in the entire tamping work cycle compared to other actions. Therefore, the arm is required to keep pulling the joystick for most of the time in the entire tamping process. Such long-term operation can easily cause arm fatigue. Summary of the invention

[0004] The technical problem to be solved by the present invention is that in the unhooking construction mode of the dynamic compaction machine, pulling the joystick for a long time easily leads to arm fatigue. To solve the above problem, a dynamic compaction machine auxiliary operation control system and operation control method are provided.

[0005] The object of the present invention is achieved in the following manner: A dynamic compaction machine auxiliary operation control system, comprising: a starting device, a stopping device, a controller, and a winch driving mechanism; The starting device is electrically connected to the controller, the stopping device is electrically connected to the controller, and the hoisting drive mechanism is electrically connected to the controller; The controller receives electrical signals from the start device and the stop device, and outputs control signals to control the winch drive mechanism, thereby realizing auxiliary operation of the tamping machine.

[0006] The starting device is any one or more combinations of a mechanical switch, a virtual touch switch on a display screen, or a sensor for detecting a lifting hammer state.

[0007] The stopping device is any one or more combinations of a mechanical switch, a virtual touch switch on a display, a sensor for detecting the operating state of a winch operating lever, or a sensor for detecting the unhooking state of a rammer.

[0008] The control steps of the auxiliary operation of the dynamic compaction machine include: Step 1: During the hammer lifting stage, the starting device is triggered to send a starting signal; Step 2: After receiving the start signal from the start device, the controller continuously outputs a control signal for lifting the hammer upward; Step 3: The winch driving mechanism responds to the control signal output by the controller to drive the rammer to automatically lift upward; Step 4: When the rammer is about to be unhooked or has been unhooked, the stop device is triggered to send a stop signal; Step 5: After receiving the stop signal from the stop device, the controller stops outputting the control signal for lifting the hammer upward; Step 6: The winch drive mechanism responds to the output of the controller and stops the rammer from lifting upward.

[0009] The beneficial effects of the present invention are as follows: during the entire tamping cycle, manual operation is not required most of the time, which reduces labor intensity, reduces arm fatigue, and improves the operating comfort of the dynamic tamping machine.
