The invention belongs to the technical field of pneumatic ejector rods, and particularly relates to a combined supporting device of a pneumatic jumbolter for a mine. The combined supporting device aims at solving the problem that in the prior art, when a supporting device is used for inclined hole drilling, the direction of a drill rod needs to be adjusted many times due to high-frequency vibration. According to the scheme, the combined supporting device comprises a base of a cuboid plate-shaped structure, wherein a supporting table is fixed to the position, close to the center line of the right side, of the upper surface of the base, an arc-shaped groove is formed in the top end of the supporting table, a hinge plate is rotationally connected in the arc-shaped groove, a pneumatic ejector rod is fixed to the top end of the hinge plate, a fixing table is fixed to the top end of the pneumatic ejector rod, a drilling machine is fixed to the top end of the fixing table, and a handrail rod is rotationally connected to the right side of the fixing table. When the combined supporting device is used, the pneumatic ejector rod is started to drive the fixing table to start to ascend to start a first drill, a drill bit can be stabilized, the drill bit is prevented from swinging, then along with pushing of the drill bit, the bottom of the drilling machine can ascend along the track of a C-shaped steel guide rail, and therefore the drill bit is prevented from deviating.
Description
technical field [0001] The invention relates to the technical field of starting rock bolts, in particular to a combined support device for a pneumatic rock bolt drill used in mines. Background technique [0002] Pneumatic rock bolt rig is a roadway bolt support equipment used in coal mines. It has very prominent advantages in improving the support effect, reducing costs, speeding up roadway formation, reducing auxiliary transportation volume, reducing labor intensity, and improving the utilization rate of roadway sections. , the existing pneumatic rock bolt rigs only rely on the pillars to support when drilling holes. When drilling, people need to support the pneumatic rock bolt rig for positioning and drilling. Because the pneumatic rock bolt rig shakes greatly when drilling, so It is easy to cause the drill pipe to shift or slip, so that positioning and drilling cannot be performed. When the drill pipe slips, it is easy to cause accidents, and it is difficult to ensure the...
