The invention discloses a simple support arm for rock drilling machinery, comprising an arm body. The middle of the bottom of the arm body is provided with a recess facing inward; the section of the arm body is in the shape of a sickle; the bottom face of the arm body is evenly provided with a plurality of oil tube mounting holes; two ends of the arm body are provided with a first shaft hole and a second shaft hole, respectively; a first shaft hole position is provided with a lateral slot; one side of the arm body is provided with a lug which is provided with a lateral hole; meanwhile, the arm body is provided with a weight reduction recess in which a stepped shaft is provided; the whole section of the lug is wedged in shape. Two ends of the simple support arm are connected with a rock drilling machine body and a working head, respectively; the simple support arm is satisfactory to use, is simple in structure and low in manufacturing cost and meets the development requirements of the rock drilling machine for miniaturization and light weight.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a simple support arm for a rock drilling machine. Background technique [0002] The support arm is one of the most critical components on the rock drill, and the structural strength of the support arm directly affects the service life of the rock drill. Most of the traditional rock drill support arms are complex in structure and bulky, which not only makes the processing and manufacturing cost higher, but also is not conducive to the future development prospects of the rock drill in miniaturization and light weight. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a simple support arm for a rock drill. The support arm has a simple structure, low processing cost and is conducive to the development requirements of miniaturization and light weight of the rock drill. [0004] The purpose of the present invention ...
