Rope wheel stroke amplification on-board drilling machine

Abstract

The invention relates to a rope wheel stroke amplification on-board drilling machine. The rope wheel stroke amplification on-board drilling machine includes a slideway bottom plate and other structures. A positioning cylinder is mounted at the front end of a first-stage sliding rail, and a connecting plate is mounted on the positioning cylinder. A clamping cylinder is installed at the upper end ofthe connecting plate, the first-stage sliding rail is installed on the slideway bottom plate, one end of a propulsion cylinder is fixed on the slideway bottom plate, and the other end of the propulsion cylinder is hinged to the first-stage sliding rail. A second-stage sliding rail is installed above the first-stage sliding rail, the slideway bottom plate is connected with one end of a rope wheelassembly I, and the other end of the rope wheel assembly I is connected to the second-stage sliding rail. One end of a rope wheel assembly II is connected with the front end of the slideway bottom plate, and the second-stage sliding rail is connected with the other end of the rope wheel assembly II. A sliding seat is installed on the second-stage sliding rail, one end of a rope wheel assembly IIIis connected with the front end of the first-stage sliding rail, and the sliding seat is connected with the other end of the rope wheel assembly III. The first-stage sliding rail is connected with oneend of a rope wheel assembly IV, and the other end of the rope wheel assembly IV bypasses the second-stage sliding rail and is connected with the front end of the sliding seat. A percussion-rotary drill is fixed on the sliding seat. The rope wheel stroke amplification on-board drilling machine has the advantages of safety and stability, reliable drilling positioning, and high efficiency.

Problems solved by technology

[0002] At present, in the field of mechanized drilling construction in coal mines, manual pneumatic drilling rigs are used for drilling support, or domestic airborne drilling rigs with single functions and large foreign volumes are used. Manual pneumatic drilling rigs are labor-intensive and have great potential safety hazards; Domestic airborne drilling rigs have a single function, no drilling positioning and dismantling of drill pipes, and manual disassembly of drill pipes poses safety hazards; foreign airborne drilling rigs are large in size and have low adaptability due to the limitation of the underground roadway section, which seriously affects the excavation footage.

[0003] At present, the propulsion mechanism used by airborne drilling rigs uses primary and secondary propulsion cylinders to achieve the propulsion stroke required for construction. First, the number of cylinders is large, and each stage of propulsion requires the expansion and contraction of the cylinder to achieve a certain propulsion stroke. Due to the limitation of the cylinder structure, it is difficult to advance a larger stroke through the cylinder

If simply increasing the accumulation of the number of oil cylinders to achieve the required push stroke for downhole construction will result in a larger volume of the airborne drilling rig, which is not suitable for complex underground working conditions. In actual operation, the larger volume of the airborne drilling rig The structure not only requires a large power system, but also affects the sight of construction workers, causing safety hazards, and often causes damage to airborne drilling rigs due to misoperation
