Abstract
The invention provides a rotary drilling rig and a main winch pay-off method and a pay-off control system thereof. The pay-off method comprises the following steps that: an electro-hydraulic proportional valve is arranged on a pilot oil circuit of a main valve and a pressure of pilot oil is controlled by the electro-hydraulic proportional valve to control the position of a valve element of the main valve so as to control the opening of a valve port, thereby controlling a rotating speed of a main winch motor controlled by the main valve; and when a drill rod is paid off to a preset position, the pressure of the pilot oil of the main valve is controlled to be reduced by the electro-hydraulic proportional valve, the valve element of the main valve moves and the opening of the valve port is reduced so as to reduce the flow of pressure oil entering the main winch motor and reduce the rotating speed of the main winch motor, thereby reducing a descending speed of the drill rod and implementing the soft contact of the drill rod and a power head. According to the invention, when the drill rod is close to a power head buffering device, a pay-off speed of a main winch can be effectively reduced, the fierce collision between the drill rod and the power head can be avoided and the service life of the power head of the rotary drilling rig and the integral reliability of the rotary drilling rig can be improved.
