The Figure of description forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 shows the internal construction schematic diagram of the first embodiment of stake machine drill head of the present invention;
Fig. 2 shows the external structure schematic diagram of the stake machine drill head of Fig. 1;
Fig. 3 shows the structural representation of the second embodiment of stake machine drill head of the present invention.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
The invention provides the first embodiment of the stake machine drill head of preformed pile, be applied particularly to the construction of prefabricated piles of hollow concrete, specifically see Fig. 1 and 2, stake machine drill head comprises bit matrix 1, cuts native parts 2 and has the expansion wing 3 boring pick cutter, cut the front end that native parts 2 are arranged on bit matrix 1, there is the expansion wing 3 boring pick cutter and be arranged on bit matrix 1 swingably, expand the wing 3 to rotate with bit matrix 1, and by changing the radius of clean-up boring pick cutter and formed around rotating of bit matrix 1 relative to the swing of bit matrix 1.
When the stake machine drill head of the present embodiment carries out middle pick engineering method pile sinking, first undertaken boring soil excavation by the native parts of cutting on bit matrix top, the expansion wing is now the first state; When bit matrix reaches near bearing stratum, control to expand the wing carry out outer pendulum and be in the second state, cooperation like this by cutting native parts and the expansion wing is carried out construction and is cut the earth, gases at high pressure or cement paste is injected by pressure valve nozzle, thus optimize the pile foundation form of different engineering when different ground soil property, when pile foundations different needed for different building, the accommodative ability of environment of drill bit can be made stronger.And can ensure construction quality, also improve efficiency of construction, constructing operation is convenient and swift.The safety, quality and the hidden danger to surrounding environment influence that exist in work progress can be eliminated simultaneously.
Further preferably, the first end expanding the wing 3 installing drill pick cutter has first state of fitting with bit matrix 1 and second state of putting relative to bit matrix 1 outward to the present embodiment.When the front end of bit matrix 1 is construction, drill bit carries out the one end of boring soil, expands the second state of the outer pendulum of the wing 3 see Fig. 1, expands the first state of the laminating of the wing 3 see Fig. 2.Bit matrix 1 is provided with installation portion 6, the middle part pivotable expanding the wing 3 is connected on installation portion 6, be provided with in bit matrix 1 and drive with the second end expanding the wing 3 control block hydraulic unit with 4 be connected, control block hydraulic unit with 4 swings with the first end controlling to expand the wing 3 by driving the second end expanding the wing 3.Installation portion 6 is projection integrated with bit matrix 1.The expansion wing in the present embodiment is that oil hydraulic type regulates pendulum angle, and namely control block hydraulic unit with 4 drives the first end of the expansion wing 3 to move along the bearing of trend of bit matrix, and drives the second end expanding the wing to expand in the middle part of the wing as pivotal axis swings.The scope that drill bit is applicable to pile tube is diameter is 600mm to 1200mm.It is 300mm to 850mm that drill bit closes diameter range.It is 650mm to 1800mm that drill bit opens expansion wing diameter.During use, according to different needs, by hydraulic control control device, the degree of closing expanding the wing is controlled, reached the aperture of required different size in construction, and efficiency of construction can be improved, reduce noise according to the native parts of cutting of the different choice different size of quality
The sidewall of bit matrix 1 is fixedly connected with helical blade 5.The Conventional wisdom of those skilled in the art is all known, and when manufacture craft, the shape of helical blade 5 is arranged on and expands the motion that the wing 3 place can not affect the expansion wing 3, and can give the space expanding wing laminating bit matrix.Helical blade 5 extends to the top of bit matrix 1, and as shown in Figure 1, the top end that helical blade 5 is positioned at bit matrix 1 is provided with brill pick cutter, and arranging brill pick cutter can increase the native efficiency of brill on helical blade, alleviates the frictional force of cutting native parts.
Bit matrix 1 has pressure valve nozzle 7 and hollow pipe 8, and pressure valve nozzle 7 is multiple and is arranged on the front end place of bit matrix 1 relatively symmetrically, and pipeline 8 is arranged on bit matrix 1 inside and is communicated with nozzle 7.Pipeline 8 can carry out slip casting, when the expansion wing of confirmation drill bit is outer pendulum state, by nozzle, slurries are sprayed into bearing stratum, simultaneously, bit matrix drives the expansion wing to proceed to rotate to stir bearing stratum, the grit of cement paste and bearing stratum is stirred fully, reaches the object of building and expanding napiform root and pile tube is inserted.The stake machine drill head of the present embodiment can operation on one side while carry out jet to reach the effect of loosening the soil, carry out passing into gases at high pressure carrying out 8, pipeline in jet process.
Preferably, in order to increase efficiency of construction, arranging the expansion wing 3 is that multiple and along bit matrix 1 sidewall circumferential direction is uniformly distributed.In the present embodiment cut native parts 2 for be fixedly connected on the top of bit matrix 1 brill pick cutter.By drill bit power current table and the display expanding wing hydralic pressure gauge, realize visual construction, staff can bore the overall process of native pile sinking in driver's cabin monitoring.
Present invention also offers the second embodiment of the drill bit of preformed pile, specifically see Fig. 3, the stake machine drill head of the present embodiment comprises bit matrix 1, cuts native parts 2 and has the expansion wing 3 boring pick cutter, the structure of stake machine drill head is all identical with the stake machine drill head of the first embodiment with annexation, difference be only, the present embodiment cut native parts 2 for being fixedly connected on the apex point on bit matrix top.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
