technical field
[0001] The invention relates to the technical field of mining equipment, in particular to a drilling rig propulsion control system and method. The invention also relates to a drilling rig comprising a drilling rig propulsion control system. Background technique
[0002] In the construction of unfavorable geological tunnels such as weak surrounding rocks, drilling rigs are mostly used for long-distance advanced geological prediction, outburst prevention, grouting and water sealing, pipe sheds, anchor cables, anchor rods and other methods to ensure tunnel construction. Existing drilling rigs mostly use hydraulic valves or manual control valves to control the advancing speed of the drill pipe. Among them, hydraulic control and manual control both involve control components such as various control valves. The number and types of parts involved are large, and installation and maintenance are difficult and costly. In addition, the hydraulic valve has the defect o...
