Design of ZHDN-SDR 150A High-Frequency Sonic Drilling Rig
Abstract:This article mainly introduces the design and verification test of ZHDN-SDR 150A high-frequency sonic drilling rig, to provides theoretical basis and technical guidance for its application in the investigation and remediation of contaminated sites. The overall design scheme and the main performance parameters of the drilling rig was discussed, meanwhile the structural design and technological innovation of the high-frequency sonic power head, the main components of the machine, and the auxiliary drilling tools was systematically analyzed. The drilling rig applied in two different soil formations was tested and verified, and the parameters of the design requirements were met. The comparison of the verification results between the ZHDN-SDR 150A drilling rig and similar ones at home and abroad shows that the main performance parameters and key equipment of the rig have advanced domestically and reached equivalent standard internationally. This developed drilling rig has prominent advantages with regard to vibration frequency, stratum applicability, and life span of auxiliary drilling tools, but has shortcomings in terms of drilling efficiency decreasing under hyperthermal condition and the rig’s intelligent and automation level. Therefore, it is necessary to further develop new materials with high temperature resistance and hardness, and to improve the remote wireless control system.
