Abstract
The utility model discloses a pneumatic-leg type frame of a rock drill capable of accurately drilling holes in multiple angles. The pneumatic-leg type frame comprises a guide rail, supporting bolts and two two-way pneumatic-leg type supporting columns. The guide rail comprises a guide rail body and a fixing beam. The guide rail body is fixed on the fixing beam. A plurality of holes are formed in the fixing beam. The two-way pneumatic-leg type supporting columns consist of pneumatic-legs and connecting sections. A plurality of holes are formed in each connecting section. The supporting bolts penetrate the holes in the fixing beam and the holes in the connecting sections to fix the guide rail between the two-way pneumatic-leg type supporting columns. The two-way pneumatic-leg type supporting columns replace for pneumatic-leg type supporting columns to support in a top-bottom plate in a coal road, the rock drill is fixed without manual handling and good in drilling stability. By the guide rail and a recessed chute, the rock drill drills holes along a fixed angle and is less prone to shaking, thus drilling angle is accurate and drilling quantity is high. The hexagonal prism supporting bolts are respectively connected with the hexagonal holes in the guide rail and not easy to rotate, so that accurate and stable direction of the guide rail is achieved.
