Pre-embedded hole drill carriage for coal mine

Abstract

The invention discloses a pre-embedded hole drill carriage for coal mine. The pre-embedded hole drill carriage for the coal mine comprises a drilling mechanism, a traveling chassis and a driving control part, the driving control part is arranged at the front of the traveling chassis, and the drilling mechanism comprises a rotating device arranged above the middle of the traveling chassis, a lifting device arranged on the rotating device, and a drilling device arranged on the lifting device in a sliding mode. The pre-embedded hole drill carriage for the coal mine is reasonable in structure design, good in rigidity, free in traveling, reliable, capable of working under a hostile environment, narrow, convenient to give another the right of way in a narrow coal mine roadway, and capable of realizing the safe, effective and mechanical working targets of the pre-embedded hole construction of the coal mine of China, and the pre-embedded hole drill carriage is a very ideal pre-embedded hole construction device.

Description

technical field [0001] The invention relates to the field of coal mine pre-buried hole construction, in particular to a coal mine pre-buried hole drilling vehicle. Background technique [0002] China's energy reserves are in the state of "short of oil, less gas, and rich in coal". According to statistics, coal accounts for more than 70% of China's primary energy consumption for a long time. Although with the rapid growth of China's economy, other new forms of energy However, the consumption of coal continues to increase. It is speculated that by 2020, the proportion of coal in my country's primary energy consumption structure will still be as high as 60%. [0003] According to statistics, my country produced 3.7 billion tons of coal in 2013, accounting for about 46% of the global total, and its coal consumption was about 4 billion tons, accounting for about 49% of the global total. More than 90% of my country's coal production comes from underground mining. Underground minin...

AI Technical Summary

Problems solved by technology

When workers install underground pipelines in coal mines, they use hand-held coal electric drills or pneumatic drills to drill the side panels or pre-buried holes on the top of the roadway. The workers have high labor intensity, low labor efficiency, and no safety guarantee, especially in spraying. When drilling pre-buried holes with a diameter greater than 50mm in roadways or concrete-supported roadways, the construction work is difficult and the efficiency is extremely low

[0005] This shows that the above-mentioned existing coal mine drilling equipment with pre-buried holes obviously has inconvenience and defects in use, and needs to be further improved urgently
