Abstract
A pile drilling machine drill bit comprises a drill bit seat and a drill rod, wherein through holes are formed in the center of the drill bit seat and the center of the drill rod, water is injected into the top end of the drill rod and can flow into the bottom of the drill bit after the drill rod and the drill bit seat are connected, the drill bit seat is connected to an annular support through a supporting rod, a fixed tool rest is arranged on the annular support and the drill bit seat and is a drill bit rack consisting of multiple frameworks at a certain taper, the tail ends of the frameworks of the fixed tool rest are connected with a movable tool rest through connectors, and drilling tools are arranged on the fixed tool rest and the movable tool rest. The pile drilling machine drill bit adopts the mode that the movable tool rest and the fixed tool rest are combined, the drill bit can be taken out under the situation that a drill hole is provide with a hole protecting pipe, and the pile drilling machine drill bit can also perform construction in an underground drift sand formation under the matching of the hole protecting pipe, and is high in working efficiency and simple, convenient and flexible to operate.
Description
Technical field
The present invention relates to a kind of construction, with boring stake machine, especially relates to a kind of drill bit boring stake machine.
Background technology
Construction pile foundation plinth is very crucial, and pile foundation includes prefabricated pile and bored concrete pile two class, the construction party of bored concrete pile
Method divides immersed tube bored and two kinds of drill-pouring.Cast-in-situ bored pile is to go out to meet the hole of design code with boring stake machine drill, is then boring
In hole, insertion steel reinforcement cage concrete perfusion forms.Existing brill stake machine, include drill bit, drilling rod, drilling cramp, Slarry cycling apptss and move
Power apparatus.Drill bit is connected on drilling rod, drilling rod connecting power device, and drilling rod is hollow, and power set drive bit bore
Meanwhile, from the water filling of drilling rod top, the soil that drill bit gets out is stirred into mud by the water constantly flowing into from drilling rod to Slarry cycling apptss
Flow out boring outer.The existing drill bit boring stake machine is to be divided into all size by diameter difference, selects the drill bit of dimension during boring
Construction, drill-shape is relatively fixed, and runs into drift sand formation or small-sized solution cavity just cannot be carried out in work progress.
Content of the invention
In order to solve in prior art, bore the problem that drill bit of pile machine cannot be constructed in underground drift sand formation, the invention provides
A kind of brill drill bit of pile machine, this brill drill bit of pile machine can solve the problem that the problem of underground drift sand formation drilling construction under the cooperation of guard aperture pipe.
The present invention solves technical problem and be the technical scheme is that a kind of brill drill bit of pile machine, including drill headstock and drilling rod,
Described drill headstock and described drilling rod be provided centrally with through hole, described drilling rod and described drill headstock connect after from described drilling rod top
Water filling can flow into drill bit bottom, and described drill headstock connects on a toroidal support by support bar, in described ring support, described
On drill headstock, immovable support is set, the drill bit frame that described immovable support is made up of with certain taper a plurality of skeleton, described
Every skeleton tail end of immovable support connects movable carriage by connector, and described immovable support and described movable carriage are arranged
Drill.
Wherein, described immovable support be integrally fixed on described drill headstock and described ring support for installing described drill
Umbrella skeleton；Described movable carriage be can on described immovable support upset activity the bone for installing described drill
Frame.Described drill headstock and described drilling rod when power set drive rotation, the brill on described immovable support and described movable carriage
Knife pierces stratum, and native rock ballast is stirred into mud by the water of inflow in described drilling rod and flows out outside boring.When drill bit enters underground drift sand formation
When, the boring above drill bit is inserted the guard aperture pipe consistent with bore diameter, by the hole wall of guard aperture protection of pipe drift sand formation boring
Do not subside.When taking out drill bit after the completion of boring, the described movable carriage on drill bit folds under described guard aperture pipe barrier effect,
Drill bit takes out from described guard aperture pipe.
As further technical scheme, described ring support arranges draw-in groove, described company at corresponding described movable carriage
Fitting is articulated elements, and described movable carriage is hinged on described immovable support and can launch and fold, and described movable carriage launches
When be stuck in described draw-in groove and be stretched over outside the circle of described ring support, described movable carriage departs from described draw-in groove simultaneously when folding
Go back in the circle of described ring support.
The invention has the beneficial effects as follows: a kind of drill bit of pile machine of boring due to the present invention employs movable carriage and immovable support
In conjunction with mode, drill bit can be taken out in the case of being provided with guard aperture pipe in the borehole, this brill drill bit of pile machine in guard aperture pipe
Under cooperation, underground drift sand formation also can be constructed, high working efficiency and convenient and flexible operation.
