Abstract

The invention relates to a chassis of a drilling machine for a rock bolt on an electric transmission line. The chassis comprises a cross arm and a bracket, wherein the bracket is arranged vertical to the cross arm; the bracket is composed of two support beams and a support rod, the two support beams are arranged in parallel, one end of each of the two support beams arranged in parallel is fixed on the cross arm, and the support rod is connected between the other ends of the two support beams; a drill pipe support chassis is arranged above the bracket, and a drill pipe support is fixed on the chassis. The chassis is mainly applied to various small drilling machines for the rock bolt on the electric transmission line, is simple and convenient to produce and manufacture and low in cost, and can guarantee that the small drilling machine for a rock bolt foundation is convenient and flexible for transportation and construction.

Description

technical field [0001] The invention relates to an auxiliary equipment for construction of a power transmission line, in particular to a chassis of a rock bolt drilling rig for a power transmission line, which is mainly used in the drilling construction of various small rock bolt drilling rigs for power transmission lines. 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...
