Description

technical field [0001] The invention relates to the technical field of underground mining machinery and equipment, in particular to a drilling rig capable of automatically going up and down drilling rods and an automatic control method. Background technique [0002] As a special manifestation of rock pressure, rock burst has become the main disaster in coal mining, especially deep mining. Drilling pressure relief refers to a method of local prevention and control of rock burst by drilling holes in the coal seam impact hazard area to reduce the stress concentration of the coal body. Most of the existing drilling pressure relief construction equipment still relies on people to keep going up and down the drill pipe, which is labor-intensive and low-efficiency, and once an emergency occurs, it is often difficult for on-site construction workers to dodge, which is harmful to the workers. Physical health poses a great safety hazard. [0003] At present, some automated drilling r...

Problems solved by technology

Most of the existing drilling pressure relief construction equipment still relies on people to keep going up and down the drill pipe, which is labor-intensive and low-efficiency, and once an emergency occurs, it is often difficult for on-site construction workers to dodge, which is harmful to the workers. Physical health poses a great safety hazard

[0003] At present, some automatic drilling rigs have appeared, but the number of rod replacements is too small to meet the requirements of anti-scouring and pressure relief drilling depth, and human intervention is still required to change rods, which has not fundamentally solved unmanned drilling.

However, the automatic drilling rig with the required number of replacement rods is too bulky, and many areas with rock burst hazards cannot enter at all. Therefore, a large-capacity, narrow-body automatic drilling rig for automatically loading and unloading drill pipes is urgently needed.
