Outline
To address the issues of low automation, high labor intensity, inefficiency, and significant safety risks in traditional shaft drilling operations, which rely on manual assistance for drill pipe handling and conveying, an automated solution was proposed to meet the requirements of single-shift unmanned shaft drilling. This solution encompasses “drill pipe conveying, drill pipe grabbing, drill pipe transportation, and drill pipe unloading”. Firstly, by analyzing the automatic conveying process of the drill pipe in the shaft drilling, the functional requirements and motion characteristics of the automatic conveying of the drill pipe were clarified. Secondly, an automatic drill pipe conveying device and a hydraulic manipulator were developed, and their strength was verified using finite element analysis software. Finally, the hydraulic control system for automatic conveying and its control logic were studied, and the feasibility of the technology was verified through on-site application. Production practice have shown that the automatic conveying technology of drill pipe for shaft drilling has good positioning accuracy, motion performance and stability, and can realize accurate and quick conveying, grabbing, transporting, and storing drill pipes. This technology can reduce the number of workers, decrease the safety risks, and improve comprehensive operational efficiency, meeting the practical engineering needs of efficient construction of single-shift shaft unmanned drilling.
