AI Technical Summary
During oil drilling, the threads at the drill pipe connection are prone to accumulating impurities such as mud, sand, and oil stains, leading to unstable connections and affecting the safety and efficiency of drilling operations. Manual cleaning is time-consuming, labor-intensive, and incomplete.
A gantry-type iron drill rig for oil drilling was designed, equipped with a cleaning mechanism. Through the cooperation of annular pipe and nozzle, the threads at the drill pipe connection are automatically cleaned. The annular pipe is moved by a power source and cleaned by the nozzle. The guide rod and fixing block ensure stability, remove impurities and improve cleaning efficiency.
It enables automated cleaning of drill pipe joints, improves cleaning efficiency, ensures clean drill pipe surfaces, avoids poor meshing caused by impurities, and ensures the safety and stability of normal use and operation of drill pipes.
