Problems solved by technology

Most of the traditional large-diameter down-the-hole drilling rigs are integrated with the air compressor. The machine is heavy, bulky, inconvenient to move, and poor in maneuverability.
Drilling rigs and air compressors are easily affected by dust generated during drilling, easy to wear, high maintenance costs, and short service life
In addition, because the drill pipe of the large-aperture down-the-hole drilling rig is thick and long, and the drill frame is large and high, the traditional large-aperture down-the-hole drilling rig uses a fixed drill frame or a pitch-down drill frame, and the drilling angle cannot be adjusted or the adjustment angle range is small. , can not meet the needs of multi-directional drilling, only one hole can be drilled in one walking positioning, the operation range is small, and the auxiliary operation time is long

Abstract

The invention discloses a large-aperture split arm type downhole drill which comprises a stand (4), a drilling frame (10), a walking chassis and an air compressor, wherein the air compressor and the stand (4) are arranged in a split type; the air compressor and a drilling machine are connected by using a high-pressure air pipe; one end of a drilling arm (15) is articulated with the stand (4), while the other end is articulated with the drilling frame (10); a drilling frame hoisting oil cylinder (16) and a drilling frame deflection oil cylinder (14) are arranged between the drilling frame (10) and the drilling arm (15); and a drilling arm hoisting oil cylinder (18) and a drilling arm deflection oil cylinder (17) are arranged between the drilling arm (15) and the stand (4). The large-aperture split arm type downhole drill has convenient movement, good maneuverability, small influence on the drilling machine and the air compressor by dust generated by drilling, difficult machine abrasion, convenient maintenance, long service life and wide drilling operation range.

Description

technical field [0001] The invention relates to a drilling machine, in particular to a large-aperture split-arm type down-the-hole drilling machine. Background technique [0002] Down-the-hole drilling rigs are widely used in blast hole drilling operations in metallurgy, coal, building materials, railways, hydropower construction, national defense construction, and earthwork. Most of the traditional large-aperture down-the-hole drilling rigs are integrated with the air compressor. The machine is heavy, bulky, inconvenient to move, and has poor maneuverability. Drilling rigs and air compressors are easily affected by dust generated during drilling, are prone to wear and tear, have high maintenance costs, and have a short service life. In addition, because the drill pipe of the large-aperture down-the-hole drilling rig is thick and long, and the drill frame is large and high, the traditional large-aperture down-the-hole drilling rig uses a fixed drill frame or a pitch-down dr...
