Detailed description of the invention
In existing lithosphere pile foundation construction, construction technology and construction equipment cannot reach low cost, high efficiency construction target, and conventional construction facility efficiency of construction in lithosphere is extremely low, high to the performance requirement of machinery own, and construction limitation is large.The embodiment of the present invention provides a kind of lithosphere piling drill bit.
As shown in Figure 1, Figure 2 and Figure 3, lithosphere piling drill bit, comprises multiple bit unit, is provided with fastening devices described in each between bit unit, and described bit unit comprises drill hammer 1 and drives the impulse drive means 6 of described drill hammer reciprocating impact.Bit unit is connected as one by fastening devices, can realize drill bit integral-rotation and cut, and each bit unit again can independently impact grinding rock, reaches the drilling effect of impact grinding.
Sliding support face 2 is provided with between drill hammer 1 described in each, sliding support face 2 achieves the mutual support between each adjacent drill hammer 1, the opposing of each drill hammer 1 can be strengthened and rotate the shearing force produced, thus prolongation life cycle, when impulse drive means drives drill hammer to hit, drill hammer moves back and forth, the sliding support face moment keeps holding state, the mutual strength of drill hammer is offset, fracture and the damage of drill hammer can be reduced, improve drilling efficiency, add application life.
Described fastening devices comprises drill headstock 3, and described drill headstock 3 is provided with pilot hole 4, is slidably fitted with described drill hammer 1 in described pilot hole 4, and described drill headstock 3 is provided with described impulse drive means.Described fastening devices can also adopt other forms so that carry out increase or the minimizing of bit unit, like this along with the increase of bore diameter, can increase bit unit until meet the requirement in drilling well aperture.
The front end face of described drill hammer 1 is ladder platform 5, and ladder platform 5 can make bore diameter produce alternately change, decreases and creeps into difficulty, increase drilling efficiency, reduce the damage of drill hammer.
Described impulse drive means 6 is hydraulic impact hammer or pneumatic striking mechanism.
Described drill headstock is provided with the separate impulse drive means corresponding respectively with drill hammer described in each 1.Also comprise the driving control device controlling impulse drive means alternation described in each.By drive control device controls impulse drive means alternation described in each, drill hammer is made alternately to hit rock stratum, add drilling efficiency, and sliding support face makes the mutual support between each adjacent drill hammer, enhance the ability of the shearing force that the revolution of opposing drill bit produces, make impact head have longer application life.
Drill hammer is adopted to replace existing hobboing cutter, sliding support face 2 is provided with between drill hammer 1 described in each, back and forth rock stratum is hit while mutually supporting, weaken drill bit self and rotate the cutting force, the impact force of impulse drive means generation and the extruding force of stake holes surrounding that produce, extend the life cycle of drill hammer, the ladder platform of drill hammer can make bore diameter produce alternately change simultaneously, reduces and creeps into difficulty, increase drilling efficiency, reduce the damage of drill hammer.
Comprise the above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
