Rope gets in-core tube assembly elevator

Technical Field

The utility model belongs to the technical field of the drilling equipment technique and specifically relates to a rope gets in-core tube assembly elevator is related to.

Background

The wire-line coring drilling process is a drilling method which is used for completing coring work by fishing a core pipe with a core from the bottom of a hole through a steel wire rope and a special fishing tool without extracting the core through a drill rod after finishing one-time coring drilling in the drilling process. The drill assembly is generally comprised of an inner tube assembly and an outer tube assembly, the outer tube assembly being driven by a drill string to drill the borehole and the resulting core entering the inner tube for storage. When the inner pipe assembly needs to be lifted out, the inner pipe assembly is mainly lifted out through a fisher to fish the core. In practical application, the length of the fisher and the length of the inner pipe assembly influence the height of the drill rig, and the fisher in the prior art is relatively long, and the typical length is about 2 meters. So that the height of the boom is typically at least 5 m above. When a traditional fisher is used for fishing the inner pipe assembly to take a core, after the fisher lifts the inner pipe assembly out of a drill hole, the drill rig is poor in adaptability, heavy, poor in stability and high in cost due to the fact that the total length of the inner pipe assembly and the fisher is long and a drill frame with a large height needs to be used; if a drill frame with larger height is not used, the fisher is taken down after the fisher lifts the inner pipe assembly out of the hole, and the inner pipe assembly is lifted out of the hole by constructors, so that the labor intensity of the constructors is increased in specific operation, and certain danger exists.

SUMMERY OF THE UTILITY MODEL
