Technical Field

The invention relates to the technical field of tunneling drill rigs, in particular to a tunneling drill rig suitable for narrow roadways.

Background

At present, underground mine exploitation in China mainly adopts an artificial drilling and blasting method for construction, the artificial exploitation determines that the section of a roadway cannot be too large, main exploitation equipment is a pneumatic drill, and only a few mines use tunneling drill trucks with narrow roadway construction capacity to replace manual exploitation. In the prior art, the name is: a development drill carriage (patent application number: 201620699469.3) for small section is disclosed, as shown in fig. 4, its carriage is an integral type, and its whole machine mainly adopts the mode of crawler running, fixed length drilling arm and external use of tail portion detachable power unit to attain the goal of reducing overall size and raising whole machine trafficability. The power unit with the detachable tail part is formed by adding a group of independent power units driven by an engine at the rear end of the whole machine, the independent power units are mutually independent of an original motor pump station of the whole machine, when the drill carriage needs to travel for a long distance, the detachable power units can be used for providing power, when the turning radius of a roadway is too small and the turning is difficult, the power units can be detached, and the motor pump station is used for completing the turning with a small radius. Because the frame formula is as an organic whole, when the complete machine need be disassembled, go into the well through the cage, the integral type frame must have the problem that can't go into the well. The crawler-type travelling mechanism is low in running speed and poor in flexibility, and the time of a transition process can be prolonged when the equipment is transitioned for a long distance. The drill boom adopts a fixed-length mode, so that the whole machine operation range is small, the whole machine operation range cannot adapt to a larger range of roadway sections, and meanwhile, the drill boom does not have an automatic parallel keeping function, so that the hole aligning precision is poor, and the hole aligning period is long. The power unit can be dismantled to its afterbody and be engine drive, and the complete machine normal walking is motor drive, and the length of complete machine cable is limited, and this has just caused long distance transition walking, need constantly carry out the removal of block terminal and the wiring of cable, if can dismantle power unit through the afterbody and walk, complete machine length can increase, and the trafficability characteristic of complete machine will reduce again.
