Description
Technical field
The utility model relates to a kind of extracting tool, particularly relates to a kind of columnar drill tool special for dismounting.
Background technology
The columnar drill huge market demand, it has the features such as structure is simple, drilling efficiency is high, applied widely, and enjoys vast construction user to like.But during columnar drill dismounting at present, there is no special instrument, impactor is knocked mainly through manually using sledgehammer, shake loose impactor front connector screw thread, with hand tools such as box spanners, columnar drill is dismantled, be easy to damage impactor outer shell, shorten the service life of impactor, and bit change-over is frequent, causes cost to raise.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of columnar drill tool special for dismounting, and its structure is simple, safe and convenient, improves operating efficiency, energy-conserving and environment-protective.
The utility model solves the technical scheme that its technical problem adopts:
Described columnar drill tool special for dismounting, comprise handle, jaw circle, shelves head and lead, handle and jaw circle are welded as a whole, jaw circle both sides are respectively equipped with the shelves head of dissymmetrical structure, jaw circle both sides are also respectively equipped with arc bump, handle is provided with bracing frame, and bracing frame is connected with lead, and lead is hollow-core construction.
The connected mode of described lead and bracing frame is for welding.
The material of described handle, jaw circle, shelves head and arc bump is high manganese steel sheet.
Columnar drill is provided with and returns slurry passage, and described lead can inject and return in slurry passage, is derived by the slurries returned out, safety and environmental protection.
Columnar drill both sides are provided with air discharge duct, and described shelves head can be stuck on air discharge duct, and the jaw circle described in increase is to the dynamics of holding of drill bit.
Described arc bump, the arc-shaped concave that can be provided with columnar drill matches, and the jaw circle described in increase is to the dynamics of holding of drill bit.
When need dismantle drill bit, that successively lead is aimed at that drill bit is provided with returns slurry passage, shelves head is stuck on air discharge duct, arc bump is stuck in arc-shaped concave that drill bit is provided with, then by jaw snare on drill bit, manual rotation is hand, drill bit is dismantled, the slurries returned out in process are derived by hollow guiding post, and access container, safety and environmental protection.
The beneficial effect that the utility model has is:
The utility model structure is simple, safe and convenient, reduces labour intensity during dismounting drill bit, improves operating efficiency, prevents from damaging impactor outer shell, reduces the frequent cost changing impactor, energy-conserving and environment-protective.

Fig. 2 is the front view of the utility model bracing frame and lead.
In figure: 1, jaw circle; 2, shelves head; 3, arc bump; 4, handle; 5, lead; 6, bracing frame.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Embodiment 1
As shown in Figure 1, described columnar drill tool special for dismounting, comprise handle 4, jaw circle 1, shelves 2 and lead 5, handle 4 and jaw circle 1 are welded as a whole, jaw circle 1 both sides are respectively equipped with the shelves 2 of dissymmetrical structure, and jaw circle 1 both sides are also respectively equipped with arc bump 3, and handle 4 is provided with bracing frame 6, bracing frame 6 is connected with lead 5, and lead 5 is hollow-core construction.
The connected mode of described lead 5 and bracing frame 6 is for welding.
The material of described handle 4, jaw circle 1, shelves 2 and arc bump 3 is high manganese steel sheet.
Columnar drill is provided with and returns slurry passage, and described lead 5 can inject and return in slurry passage, is derived by the slurries returned out, safety and environmental protection.
Columnar drill both sides are provided with air discharge duct, and described shelves 2 can be stuck on air discharge duct, the dynamics of holding of the jaw circle 1 pair of drill bit described in increase.
Described arc bump 3, the arc-shaped concave that can be provided with columnar drill matches, the dynamics of holding of the jaw circle 1 pair of drill bit described in increase.
When need dismantle drill bit, that successively lead 5 is aimed at that drill bit is provided with returns slurry passage, shelves 2 are stuck on air discharge duct, be stuck in by arc bump 3 in arc-shaped concave that drill bit is provided with, be then enclosed within drill bit by jaw circle 1, manual rotation is hand 4, drill bit is dismantled, the slurries returned out in process are derived by hollow guiding post, and access container, safety and environmental protection.
