Description

Technical Field

[0001] The invention relates to the field of geotechnical engineering, and in particular to an adjustable crank arm slide rail wall drilling device and a method thereof. Background Art

[0002] In tunnel drilling and blasting construction, over-break and under-break control is a core issue that affects construction quality and cost. Traditional rock drilling rigs are limited by the lack of freedom of the mechanical arm and the large size of the end. Space (technical over-break) needs to be reserved when drilling to ensure stability, resulting in an average over-break of up to 20-30cm or even larger, forming a lining layer, causing waste of support materials (about 15% cost increase) and safety hazards. When the hydraulic telescopic drill arm is drilling, the near-face and drill rod need to be horizontal with the rock wall, and the drill rod needs to be as vertical as possible to the rock wall.

[0003] However, due to the over-excavation of up to 20-30cm and the presence of the lining layer, when the drill arm is rotated, it is easy for the drill arm to contact the lining layer of the top rock wall. When the drill arm contacts the top lining layer, the drill rod is also difficult to be perpendicular to the rock wall, and the near-face cannot reach the level of the rock wall, and the drilling angle of the hydraulic telescopic drill arm cannot be achieved. There is generally an error of ±5°, resulting in unqualified drilling quality and affecting the subsequent construction quality. The hydraulic telescopic drill arm of the prior art has problems such as low angle adjustment accuracy (±5° error) and poor wall adhesion. For this reason, we propose an adjustable curved arm slide rail wall drilling device and method to solve the above problems. Summary of the invention
