Embodiment Construction

[0018] As shown in the figure, a multi-angle coal rock drilling rig is provided with a motor 8 in the track groove of the horizontal guide rail 1, and the motor 8 is connected with a propulsion cylinder 10 in the track groove of the horizontal guide rail 1. Drill rod 9 is connected with motor 8 . Motor 8 is a variable speed motor, which can be driven by electricity or hydraulic pressure. The center of the drill rod 9 is provided with a through hole 26 through which high-pressure water or air can be introduced for cooling or powder discharge during the drilling process. The drilling machine also includes a lifting guide rail 2, and the lifting guide rail 2 and the horizontal guide rail 1 are arranged in a cross. A sliding sleeve 4 is provided on the lifting guide rail 2 . The horizontal guide rail 1 is arranged on one side of the sliding sleeve 4 , and its middle is connected with the sliding sleeve 4 through a rotating shaft 12 . Two oblique telescopic support arms 5 connec...

Abstract

The invention discloses a multi-angle coal petrography drilling machine relating to a drilling machine used for pumping gas under a coal mine. The multi-angle coal petrography drilling machine mainly comprises a horizontal guide rail, a lifting guide rail, a base, a drill rod and a motor, wherein the horizontal guide rail is connected with the lifting guide rail by a sliding sleeve arranged on the lifting guide rail, the sliding sleeve is symmetrically provided with two obliquely stretching supporting arms connected with the horizontal guide rail, two ends of the horizontal guide rail are provided with downward stretching supporting arms which are vertically downward, a drill rod driving seat is arranged in a track groove of the horizontal guide rail, and a thrust cylinder is also arranged in the track groove of the horizontal guide rail. The machine simplifies the structure of the drilling machine, and saves cost; and the drilling machine has a small volume, is convenient to use in a narrow mine, and can realize the drilling operation at various angles under the condition that the position of the drilling machine is not moved.

Description

technical field [0001] The invention relates to a drilling rig for underground gas drainage in coal mines, in particular to a multi-angle coal rock drilling rig. Background technique [0002] In order to eliminate the hidden dangers of water seepage and gas accidents in coal mines, ensure the safety of coal mine production, and prevent major accidents caused by water seepage and gas outbursts, the state has made the work of preventing water seepage and gas outbursts in coal mines mandatory measures. Gas drainage and long-distance water detection are fundamental measures to control coal mine gas and water seepage accidents. The drilling tools currently used usually cannot drill coal holes and rock holes at the same time, and have the disadvantages of coal seam sandwiching and lost drilling. There are usually multiple mining faces that need to be drilled in the roadway under the coal mine. Usually the drilling rigs used in coal mines are bulky and heavy, and it is very incon...
