Automatic lifting drilling machine for high-position punching of medium-thickness coal seams and implementation method thereof

Abstract

The invention discloses an automatic lifting drilling machine for high-position punching of medium-thickness coal seams. The automatic lifting drilling machine comprises a lifting unit, a rotating unit and a punching unit. The lifting unit comprises a front hydraulic cylinder and a rear hydraulic cylinder, cylinder bodies of the front hydraulic cylinder and the rear hydraulic cylinder are fixed tothe rotating unit, and piston rods of the front hydraulic cylinder and the rear hydraulic cylinder are connected with the punching unit. The automatic lifting drilling machine has the following advantages that the problems that an existing drilling machine cannot effectively conduct high-position punching of the medium-thickness coal seams, and adjusting of the punching angle is not flexible aresolved, automatic lifting, adjusting of the punching pitch angle, and adjusting of the horizontal rotating angle can be achieved, and the punching accuracy, the high-position punching efficiency and safety are improved.

Description

technical field [0001] The invention relates to an automatic lifting drilling machine for high-position drilling in medium-thick coal seams and a realization method thereof, belonging to the field of coal mine drilling machinery equipment. Background technique [0002] At present, in the high-level drilling construction of medium-thick coal seams in underground coal mines, auxiliary devices such as temporary supports and chain hoists are generally used to increase the drilling height of the drilling rig. Stability, resulting in accidents such as drill sticking are extremely prone to occur during construction. [0003] The chassis and fuselage of existing coal mine crawler drilling rigs generally adopt a fixed connection method, and the horizontal azimuth of drilling can only be adjusted by adjusting the differential speed of the crawler traveling mechanisms on both sides. lead to low construction efficiency. [0004] The existing patent application number 200920103136.X di...
