Abstract

The underground drill rig is too heavy, so it is difficult to move and transport in the roadway with poor conditions. In order to solve the problem, ZDY1200G lightweight underground drill rig with 5052-h38 state high strength aluminum alloy as the main material is developed. The idea of light structure design and modular assembly is adopted, combined with the application of light materials. The maximum weight of single component after quick disassembly of the drill rig is 292.5 kg. The three-dimensional DIC speckle system was used to measure and analyze the strain and displacement of the aluminum alloy feed body of the drill rig under the maximum load. The maximum principal strain under the maximum rotating load condition is 0.87%, and the maximum displacement of the fuselage is 6.317 mm under the maximum lifting condition. No plastic deformation was exerted on the fuselage to meet the use requirements. After the development of the drill rig, a field industrial test was carried out in a mine in Cangyuan County, Yunnan Province. A coring hole with a depth of 512.68 m and a slope of 43° was completed. The test results showed that the underground drill rig made of aluminum alloy is equivalent to the underground drill rig with carbon steel as the main material in strength, rigidity and reliability, and has the advantages of convenient relocation and transportation, which can be better applied to the underground drilling construction.
