Technical Field

The invention relates to the technical field of drilling machine tools, in particular to a continuous slurry (gas) supply type elevator.

Background

When a drill burying accident occurs in a domestic rotary table drilling machine, under the condition that a drill rod is not detached, the drill can be lifted while mud (high-pressure air) is introduced, when the active drill rod is completely lifted, the active drill rod needs to be detached and then the round drill rod is lifted, at the moment, mud or high-pressure air cannot be introduced into the drill rod in the hole, the drill rod can only be lifted by using a common lifter, but under the condition that mud or high-pressure air is not introduced due to the fact that the drill is buried in the hole, the drilling tool is difficult to lift.
