Abstract

An efficient drill pipe delivery system can reduce the time of starting and lowering drilling operations, reduce the labor intensity of workers, and improve the efficiency of drilling construction. At present, most of the ground emergency rescue truck-mounted drilling rigs use manual assistance to change rods, which is less efficient, labor-intensive and has safety hazards. In order to improve the efficiency and safety of rod changing, we developed a hydraulic lifting device which is applicable to various drilling tools and has the function of monitoring the snapping status. The device directly grabs the drill pipe to lift and lower the drill column in the starting and lowering operation, replacing the original way of threaded connection between the output shaft of the power head rotator and the drill column. The buckling monitoring alarm system of the device monitors the buckling status of the lifting device in real time. A finite element method was used to simulate and optimize the structure of the device for two actual operating conditions and key connecting shafts. The results show that strength of the device meets the design requirements. This study should, therefore, be of value to practitioners wishing to drill pipe conveying system.
