Multifunctional split-type caterpillar drilling machine for coal mine

Abstract

The invention relates to drilling and exploring machinery, in particular to a multifunctional split-type caterpillar drilling machine for a coal mine. At present, an all-hydraulic drilling machine for the coal mine mainly includes a split crawler type and an integral caterpillar type in terms of structure, the movement of a split crawler type drilling machine mainly depends on manual work and is slow in speed and large in labor intensity, and the stabilizing time of the drilling machine is long; the integral caterpillar type drilling machine has high requirements on transportation sizes due to larger size, and an operator and electric equipment ought to face an orifice of a drilled hole directly, which is not in conformity with usage specification requirements; the drilling machines of the two structure types are limited in regulation ranges of pitching angle, azimuthal angle and horizontal boring height or incomplete in functions, and thus are poor in technological adaptability. The multifunctional split-type caterpillar drilling machine for the coal mine comprises a drill carriage, a pump truck and a control board, wherein the drill carriage, the pump truck and the control board are mutually connected through high-pressure rubber hoses. According to the invention, by virtue of the special structure of the drilling machine, the multifunctional split-type caterpillar drilling machine achieves the advantages of small unit size, strong maneuverability, and complete functions of regulating various drilling angles, and is suitable for being used in underground narrow roadways of the coal mine and mines liable to outburst.

Description

1. Technical Field: [0001] The invention relates to drilling machinery, in particular to a multifunctional split crawler drill for coal mines. 2. Background technology: [0002] At present, the structure of full hydraulic drilling rigs for coal mines mainly has two types: split crawler type and integral crawler type. The relocation of split crawler type rigs mainly relies on manual labor, which has slow moving speed, high labor intensity, and long rig stability; integral crawler rigs The size is large, and the size requirements for underground relocation and transportation are high, and the drilling rig operator and electrical equipment must directly face the drilling hole, which does not meet the requirements of the safety use specification of prominent mine equipment. The two types of drilling rigs have limited adjustment ranges of elevation, azimuth, and horizontal opening height, and incomplete functions, resulting in poor process adaptability. 3. Summary of the invention: ...

Problems solved by technology

[0002] At present, the structure of fully hydraulic drilling rigs used in coal mines mainly has two types: split crawler type and integral crawler type. Large size, high requirements for underground relocation and transportation, and drilling rig operators and electrical equipment must directly face the drilling hole, which does not meet the requirements of the safe use of outburst mine equipment

The adjustment ranges of pitch angle, azimuth angle and horizontal opening height of the two structures of drilling rigs are limited and the functions are incomplete, resulting in poor process adaptability
