Meanwhile, the second reversing valve is opened to communicate the overflow valve control port with the oil inlet of the remote pressure regulating overflow valve, and the tension of the winch can be adjusted by adjusting the pressure of the remote pressure regulating overflow valve. When the force of the rock supporting down-the-hole hammer is smaller than the difference between the gravity of the down-the-hole hammer working device and the pulling force of the winch, the winch motor and the remote pressure regulating overflow valve automatically work under the action of the gravity of the down-the-hole hammer; the down-the-hole hammer can be correspondingly lowered for a certain distance to reach balance, and the winch can be automatically lowered along with the continuous drilling of the down-the-hole hammer. The invention can reduce the labor intensity of workers and improve the working efficiency.
