Abstract
The utility model discloses a kind of nager Kelly Stubb lever apparatus, it includes that the first hand-held component (1) and the second hand-held component (2), the end semi-circular structure of the first hand-held component (1) are connected fixing for drilling rod (5) by bolt (4) and nut (3) with the end semi-circular structure of the second hand-held component (2)；Solve prior art nager when being extracted by drilling rod after piercing, owing to rock drill weight is big, be difficult to when drilling rod is longer extract drilling rod, and be difficult to from drilling rod, take off rock drill, the safety of operating personnel is caused the technical problems such as certain threat.
Description
Technical field
This utility model relates to Kelly Stubb pole technology, particularly relates to a kind of nager Kelly Stubb lever apparatus.
Background technology
In utilizing nager boring procedure, when running into the geological structures such as joint, crack, crushed zone, mud groove, hand-held
The as easy as rolling off a log bit freezing of rock drill, is all to be extracted by drilling rod by raising nager in conventional work progress, but rock drilling
Machine weight is big, is not only difficult to when drilling rod is longer extract drilling rod, is also difficult to be taken off from drilling rod by rock drill, to operating personnel
Safety cause certain threat, in order to improve this situation, be badly in need of this rod-pulling device is improved.
Summary of the invention
The technical problems to be solved in the utility model: a kind of nager Kelly Stubb lever apparatus is provided, existing to solve
When drilling rod is extracted by technology nager after piercing, owing to rock drill weight is big, it is difficult to Kelly Stubb when drilling rod is longer
Go out, and be difficult to from drilling rod, take off rock drill, the safety of operating personnel is caused the technical problems such as certain threat.
Technical solutions of the utility model:
A kind of nager Kelly Stubb lever apparatus, it includes the first hand-held component and the second hand-held component, and first is hand-held
The end semi-circular structure of component is connected fixing for drilling rod by screw bolt and nut with the end semi-circular structure of the second hand-held component.
The length of the first hand-held component and the second hand-held component is at 50-60 centimetre.
Interior diameter 1-2 bigger than the diameter of the drilling rod millimeter of semi-circular structure.
The beneficial effects of the utility model:
This utility model simple in construction, flexible operation, it is fixed on drilling rod and can easily drilling rod be extracted, solve existing
When having technology nager to be extracted by drilling rod after piercing, owing to rock drill weight is big, it is difficult to drilling rod when drilling rod is longer
Extract, and be difficult to from drilling rod, take off rock drill, the safety of operating personnel is caused the technical problems such as certain threat.
Accompanying drawing explanation
Fig. 1 is this utility model structure schematic front view；
Fig. 2 is this utility model schematic top plan view.
Detailed description of the invention
