Abstract

The invention discloses a control system of a rotary jetting drilling rig and the rotary jetting drilling rig. The control system of the rotary jetting drilling rig comprises a control valve, a pilothandle and a controller, wherein the control valve and the pilot handle are used for controlling the speed of a power head, and the controller is arranged to be coupled with a control valve. In a drilling state, the pilot handle controls the speed of the power head; and in a rotary jetting lifting state, the controller automatically controls the control valve to do movements according to the speedset value so as to control the speed of the power head. The control system of the rotary jetting drilling rig achieves automatic control over the speed of the power head, so that the control accuracyof the speed of the power head is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a control system of a jet-jet drilling machine and the jet-jet drilling machine. Background technique [0002] The high-pressure rotary spraying construction includes two working conditions of drilling and rotary spraying lifting. In the drilling condition, the speed of the power head does not need to be adjusted and the feed speed does not need to be adjusted accurately; The rotational speed and the speed of the rotary jet lifting need to be adjusted precisely. Such as figure 1 As shown, the control system of the rotary jet drilling machine in the prior art includes a first pilot handle 1a for controlling the lifting speed of the power head, a first manual pressure relief valve 3a and a second pilot handle 2a for controlling the speed of the power head And the second manual decompression valve 4a, because the adjustment of the rotating speed of the power head and...
