Problems solved by technology

However, there are some obvious defects in its practical application. For example, there is no reliable digital monitoring of data such as oil pump pressure, temperature, mud pump pressure, and winch tension during the drilling process. The torque of the drill pipe is uncontrollable at a certain speed, and the speed and torque cannot be adjusted online steplessly according to the actual situation in the well.

Description

technical field [0001] The invention relates to the technical field of rock drilling rigs, and relates to an intelligent rock drilling rig control system. Background technique [0002] At present, the rock drilling rig is a kind of drilling by installing a drill bit on the front end of a single drill rod after the power source is changed. When drilling, the diameter of the one-time drilling machine should not be too large. When drilling a larger hole, the diameter of the drill bit needs to be gradually increased. , resulting in low efficacy. Commonly used subway tunnel excavation drilling rigs mostly use cold drill bit hard friction to drill, but they are often unable to do what they want for larger rocks with higher hardness, which places a great burden on the drill bit and drill teeth. [0003] The main advantages of existing rock drilling rigs are high transmission efficiency, low manufacturing and use costs, practical and reliable, and easy maintenance. However, there ...
