Abstract

The invention relates to a triangular support leg of a miniature drilling machine for a rock bolt of an overhead power transmission line. The triangular support leg comprises a triangular disc, disc nails, a plugging fixing clamp and a connecting ring, wherein the bottom surface of the triangular disc is provided with the disc nails, the triangular disc is provided with a through hole, the plugging fixing clamp penetrates through the through hole, the connecting ring is arranged above the triangular disc, the three edges of the triangular disc are respectively provided with a foldable plate, each foldable plate is provided with an auxiliary through hole, and auxiliary plugging fixing clamps penetrate through the auxiliary through holes. The triangular support leg has the advantages that the triangular support leg is mainly applied to a bracket of the miniature drilling machine for the rock bolts of various overhead power transmission lines, and the stable construction and drilling of the miniature drilling machine for a rock bolt foundation are guaranteed.

Description

technical field [0001] The invention relates to an auxiliary tool for construction of a power transmission line, in particular to a multifunctional triangular support foot for a small drilling rig for rock bolts of a power transmission line. Background technique [0002] The use of rock bolt foundations for power transmission lines can save raw material consumption, reduce project costs, and avoid corresponding environmental problems caused by large excavation, large blasting, or excavation of foundations, and achieve the purpose of engineering environmental protection and energy saving. Social Significance. Although rock bolt technology has been widely studied at home and abroad, it has been more and more applied to the foundation of transmission line towers in recent years. However, due to the cumbersome and bulky bolt construction machinery and equipment at home and abroad, it is difficult to be suitable for mountain transportation and installation. Therefore, although t...
