Abstract:
On the basis of analyzing the acquired hoisting capsule parameters home and abroad, manned hoisting capsule used for large and deep drilling borehole was integrated and designed, it can meet the demands of drilling borehole diameters of 580 mm to 620 mm, depth of 700 m and single man per hoisting. In the condition of safety and reliability, manned tank, guiding arrangement, anti-banging device, main tank, release device, damping device and other devices were specially designed and introduced. It was validated through simulation and field test that the tank was stable, the upper and the lower guidance were smooth, the functions of anti-banging device, release device, and damping device can meet the demands of design, key part was under normal running. Worker safety and quick hoisting rescue can be met under depth of 700 m.
