Title: Innovations by Brian B Khalighi
Introduction
Brian B Khalighi is an accomplished inventor based in Bellevue, WA (US). He has made significant contributions to the field of tunnel boring technology, holding 2 patents that showcase his innovative approach to engineering challenges.
Latest Patents
One of Khalighi's latest patents is a "Cutter assembly for tunnel boring machine with pressure compensation." This invention features a pressure-compensated cutter assembly that includes a shaft, a cutter ring assembly rotatably mounted on the shaft, and first and second end retainers non-rotatably attached to the shaft. The design incorporates rotary seal groups immersed in lubricant, which provide a moving seal between the rotating cutter ring assembly and the end retainers. A movable piston member is exposed to ambient pressures, ensuring that increasing ambient pressure will increase the lubricant pressure, thereby maintaining a small pressure differential across the seal.
Another notable patent is the "All-conditions tunnel boring machine." This invention comprises a cutter head, a main beam, and multiple shields, along with a ground conditioning work zone within the first shield. The design includes a gripper assembly and a segment erector arm for lining the tunnel. The ground conditioning work zone is equipped with probing devices to assess the terrain ahead of the cutter head, enhancing the machine's operational efficiency.
