Problems solved by technology

[0002] At present, the existing rock bolt rigs are hydraulic or pneumatic. Hydraulic rock bolt rigs mostly use hydraulic oil or emulsion. When operating in mines, if the hydraulic oil leaks, it will affect mine mining safety. For example, when using emulsion , the emulsion contains a certain amount of oil, which is directly discharged to pollute the environment
Moreover, additional water braids and a special water supply system are required on the existing rock bolter

Abstract

The invention discloses a roof jumbolter. The roof jumbolter comprises a drilling compensation hydraulic cylinder (1), a connecting assembly (2), a hydraulic motor (3) and an operating arm (4), a nail column is arranged at the bottom of the drilling compensation hydraulic cylinder (1), the end of a piston rod of the drilling compensation hydraulic cylinder (1) is fixedly connected with the bottom of the connecting assembly (2), and the hydraulic motor (3) is installed at the top of the connecting assembly (2). A water jacket (5) is movably arranged on the outer wall of a power output shaft of the hydraulic motor (3) in a sealed manner, a drill rod connector (6) is arranged at the end of the power output shaft of the hydraulic motor (3), and the operating arm (4) is movably installed at one side of the connecting assembly (2). The roof jumbolter has the advantages that water is used as a power medium and can be directly discharged, so that the operation in a mine is safer. No additional water braid is needed.

Description

technical field [0001] The invention relates to the field of drilling equipment, in particular to a roof bolt drilling machine. Background technique [0002] At present, the existing rock bolt rigs are hydraulic or pneumatic. Hydraulic rock bolt rigs mostly use hydraulic oil or emulsion. When operating in mines, if the hydraulic oil leaks, it will affect mine mining safety. For example, when using emulsion , The emulsion contains a certain amount of oil, which is directly discharged to pollute the environment. And additional water braids and special water supply systems need to be set up on the existing rock bolter. Contents of the invention [0003] Purpose of the present invention is exactly to above-mentioned deficiency, and provides a kind of roof bolt drilling rig. [0004] The invention includes a drilling compensation hydraulic cylinder, a connection assembly, a hydraulic motor and a control arm, [0005] The bottom of the drilling compensation hydraulic cylinder...
