Latest Patents
Hengjing Zhang holds a patent for an "Intelligent directional device for full rotation of drill string." This invention features an electronically controlled full rotary clutch controller that includes a drive assembly, an executive assembly, and an auxiliary assembly. The device operates in two working states: directional drilling and compound drilling. During compound drilling, drilling parameter information is collected through the main control board, which communicates with a ground processing system to transmit control signals. The main control board then manages a rotating motor that drives a screw sleeve and a push block shaft on a ball screw. This mechanism allows for the radial movement of a push block, enabling the mandrel shell to transmit torque to a roller shell, facilitating compound drilling. In directional drilling mode, the main control board reverses the rotary motor, allowing the push block shaft to pull the push block radially, while the roller shell remains stationary.
