Abstract
Description
technical field
[0001] The invention relates to the technical field of coal mine drilling equipment, in particular to a column-type emulsion drilling rig with a multi-stage gear bar dismounting and clamping. Background technique
[0002] At present, the drilling equipment used in underground coal mines mainly includes coal electric drilling rigs, wind drilling rigs, hydraulic drilling rigs, etc. In the flammable and explosive environment of coal mines, the State Administration of Work Safety has strictly restricted the use of live equipment, and it is inevitable that coal-electric drilling rigs will be eliminated; wind drilling rigs are also due to their shortcomings such as high noise, low torque, low efficiency, and short life. It is being phased out; at this stage, the large and medium-sized drilling rigs used in coal mines are mainly hydraulic drilling rigs, which are incomparable to other types of drilling rigs for their advantages such as large torque, low noise, relia...
