Abstract
The utility model provides a dual-purpose drilling broaching bit controlled by centrifugal wings, which is composed of a drilling rod, a vertical drill bit, and a horizontal broaching bit. The vertical drill bit and the horizontal broaching bit are fixed on the drilling rod, the vertical drill bit is fixed on the lower end of the drilling rod, and the horizontal broaching bit is fixed on the top of the vertical drill bit. The utility model has the characteristics of reasonable design, simple structure, easy manufacture, convenient operation, and dual-purpose capabilities of drilling straight holes and diameter changing holes, etc. Compared with common vertical piles whose straight foundation is poured by straight holes, the reinforced concrete foundation vertical pile with a plurality of back taper-shaped holes prefabricated to sugar calabash shape has higher load bearing strength and higher function for preventing foundation settlement.
Description
The utility model relates to a kind of constructional engineering machinery, and specifically a kind of centrifugal wing control that is used for using on the building operations foundation pile drilling machine is bored and expanded dual-purpose composite drill bit.
In building operations, then need on the basis, squeeze into the cement soldier piles or use rig to get out a hole, pour into reinforced concrete prefabricated one-tenth concrete pedestal soldier piles again and prevent building immerge in use so that the building foundation is reinforced as running into the loose basis of geology.In the prior art, the employed drill bit of Post hole driller can only get out the identical vertical vertical core of diameter up and down when boring, building the basic soldier piles that are prefabricated into behind the steel concrete is that diameter is identical up and down equally, and this identical existing deficiency of reinforced concrete foundation soldier piles of diameter up and down is anti-building foundation sinking poor-performing.
The purpose of this utility model provide use on a kind of basic soldier piles rig can bore the up and down identical vertical core of diameter, also can bore centrifugal wing control that diameter difference up and down has a sugarcoated haws shape vertical core and bore and expand dual-purpose composite drill bit.
The purpose of this utility model realizes in the following manner, on drilling rod, establish conventional vertical drilling drill bit and horizontal reaming bit, horizontal reaming bit is by reaching with the impeller that drilling rod is slidingly matched by impeller, connecting rod control can become the reaming wing plate of umbrella to constitute to horizontal development, when drilling rod just changes, impeller is in the effect control reaming wing plate closure of lubricated slurry, the vertical drilling drill bit gets out straight hole downwards, during as the needs reaming, rig drives the drilling rod counter-rotating, impeller upwards rises under the reaction of lubricated slurry, promote connecting rod and reaming wing plate in succession and outwards become umbrella to launch, hole wall is expanded into the inverted cone shape hole.Build into steel concrete as having to this kind in a plurality of inverted cone shapes hole, be prefabricated into sugarcoated haws shape reinforced concrete foundation soldier piles, compare with the straight shape basis soldier piles that common straight hole is built, will have bigger load bearing stength, anti-foundation settlement effect will improve greatly.
Accompanying drawing 1 bores the structural representation that expands dual-purpose composite drill bit for the centrifugal wing control;
Accompanying drawing 2 bores the plan structure schematic diagram that expands dual-purpose composite drill bit for the centrifugal wing control.
Centrifugal wing control of the present utility model is bored the structure that expands dual-purpose composite drill bit with reference to Figure of description Explain below the work.
Centrifugal wing control of the present utility model is bored and is expanded dual-purpose composite drill bit, and its structure is by drilling rod 1, hangs down Straight drill 2, horizontal reaming bit consist of, and vertical drill bit 2 is fixed on drilling rod with horizontal reaming bit On 1, vertical drill bit 2 is fixed on the lower end of drilling rod 1, and horizontal reaming bit is fixed on vertical drill bit 2 top.
Horizontal reaming bit is to be made of locating piece 3, impeller 4, connecting rod 5, reaming wing plate 6, reaming wing plate 6 is provided with notched scraper 7, the upper end of reaming wing plate 6 is joined by hinge 8 and locating piece 3, the lower end of reaming wing plate 6 is joined by connecting rod 5 and impeller 4, impeller 4 is enclosed within on the drilling rod 1 and is slidingly matched with drilling rod 1, and the two ends of connecting rod 5 are joined by hinge 8 and impeller 4 and reaming wing plate 6.
Embodiment:
It is very simple and convenient that the processing and fabricating that expands dual-purpose composite drill bit is bored in centrifugal wing control of the present utility model, and processing and fabricating gets final product shown in the by specification accompanying drawing.Vertical drill bit is identical with the employed drill bit of prior art, and each component of horizontal reaming bit all can be processed into by conventional machining technique.
It is also very simple and convenient that the use of expanding dual-purpose composite drill bit is bored in centrifugal wing control of the present utility model, the vertical drilling of whole drill bit and common drill bit was without any difference when the drilling rod of rig was just changeing, drive the drilling rod counter-rotating when having only the reaming of needs, the impeller of horizontal drill bit suitable drilling rod under the repulsion of mud upwards slides and makes the reaming wing plate be the umbrella horizontal development, hole wall is carried out horizontal cutting, make hole wall form the inverted cone shape hole, reaming finishes, driving drilling rod just changes, the reaming wing plate shrinks under the downward pulling of impeller and closes up, drilling rod rises to another degree of depth with drill bit, and the rig horizontal drill bit of driving that reverses in the same way expands second hole on another degree of depth of hole wall, the 3rd hole ...
Centrifugal wing control of the present utility model is bored the dual-purpose composite drill bit of expansion and is compared with existing technology, and has and establishes Count reasonable, simple in structure, be easy to processing, easy to use, can bore straight hole, can bore the reducing hole again Etc. characteristics, using this kind to have a plurality of inverted cone shapes hole, to be prefabricated into sugarcoated haws shape reinforced concrete foundation perpendicular Stake is compared with the straight shape basis soldier piles that common straight hole is built, and will have bigger load bearing stength, Anti-foundation settlement effect will improve greatly. Thereby, have good value for applications.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
