【 摘 要 】

At the basis of analysis on 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 580mm to 620mm, depths of 700s and single man hoisting each time. In the condition of safety and reliability, cabin, guide device, rope breaking protection device, main cabin and disconnect device, buffer device and other devices were specially designed and introduced. And the key part of upper link of hoisting capsule was simulated, function tests of capsule were did in field test. It was validated through simulation and field test that the cabin was stable, the upper and lower guide device were smooth, the functions of rope breaking protection device, disconnect device, and buffer device can meet the demands of design expect, key part was under normal running. Worker safety and quick hoisting rescue requirements can be met under depth of 700m.
