Abstract
The invention aims to provide a lithosphere piling drill to solve the problem that the construction technology and construction equipment in the existing lithosphere pile foundation construction cannot reach the construction goal of low cost and high efficiency. The conventional construction equipment is of extremely low construction efficiency in the lithosphere, has super high requirements for equipment performance itself and has the problem of big construction limitation. The lithosphere piling drill comprises a plurality of drill units, wherein fixing devices are arranged among each two drill units. The drill unit comprises a percussion drill and a percussion driving device for driving the percussion drill to give repeated percussions. The lithosphere piling drill can be applied into the field of pile foundation construction.
Description
Technical field
The present invention relates to drilling tools field, relate in particular to a kind of piling drill bit.
Background technology
In current lithosphere pile foundation construction in the world, construction technology and construction equipment cannot reach low cost, high efficiency construction target.Along with social progress, more and more higher to the shockproof requirement of building, be to solve the shockproof best method that basis is required and pile foundation is got in lithosphere.Conventional construction method efficiency of construction in lithosphere is extremely low, high to the performance requirement of machinery own, and construction limitation is large.
Summary of the invention
The object of this invention is to provide a kind of lithosphere piling drill bit, solve in existing lithosphere pile foundation construction, construction technology and construction equipment cannot reach low cost, high efficiency construction target, conventional construction facility efficiency of construction in lithosphere is extremely low, high to the performance requirement of machinery own, and there is the large problem of construction limitation.
For achieving the above object, by the following technical solutions, lithosphere piling drill bit, comprises multiple bit unit in the present invention, described in each, between bit unit, be provided with fastening devices, described bit unit comprises drill hammer and drives the impulse drive means of described drill hammer reciprocating impact.
Concrete, described in each, between drill hammer, be provided with sliding support face.
Concrete, described fastening devices comprises drill headstock, described drill headstock is provided with pilot hole, is slidably fitted with described drill hammer in described pilot hole, and described impulse drive means is installed on described drill headstock.
Concrete, the front end face of described drill hammer is ladder platform.
Concrete, described impulse drive means is hydraulic impact hammer or pneumatic striking mechanism.
Concrete, the separate impulse drive means corresponding with drill hammer difference described in each is installed on described drill headstock.
Concrete, also comprise the driving control device of controlling impulse drive means alternation described in each.
A kind of lithosphere piling drill bit that the embodiment of the present invention provides, adopt drill hammer to replace existing hobboing cutter, described in each, between drill hammer, be provided with sliding support face, in mutually supporting, back and forth hit rock stratum, the cutting force that drill bit self rotation produces, the impact force of impulse drive means generation and the extruding force of stake hole surrounding are weakened, extend the life cycle of drill hammer, the ladder platform of drill hammer can make bore diameter produce alternately variation simultaneously, reduce and creep into difficulty, increase drilling efficiency, reduce the damage of drill hammer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of a kind of lithosphere piling drill bit that provides of the embodiment of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right view of Fig. 1.
The specific embodiment
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, described in each, between bit unit, is provided with fastening devices, and described bit unit comprises drill hammer 1 and drives the impulse drive means 6 of described drill hammer reciprocating impact.Bit unit connects as one by fastening devices, can realize drill bit integral-rotation cutting, and each bit unit impact grinding rock independently again reaches the drilling effect of impact grinding.
Described in each, between drill hammer 1, be provided with sliding support face 2, sliding support face 2 has been realized the mutual support between each adjacent drill hammer 1, can strengthen the shearing force that each drill hammer 1 opposing rotation produces, thereby prolongation life cycle, in the time that 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, can reduce fracture and the damage of drill hammer, improve drilling efficiency, increased 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, on described drill headstock 3, described impulse drive means is installed.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 variation, has reduced and has crept into difficulty, increases drilling efficiency, reduces the damage of drill hammer.
Described impulse drive means 6 is hydraulic impact hammer or pneumatic striking mechanism.
The separate impulse drive means corresponding with 1 difference of drill hammer described in each is installed on described drill headstock.Also comprise the driving control device of controlling impulse drive means alternation described in each.By drive control device controls impulse drive means alternation described in each, make drill hammer alternately hit rock stratum, increase drilling efficiency, and sliding support face makes the mutual support between each adjacent drill hammer, the ability that has strengthened the shearing force of opposing drill bit revolution generation, makes impact head have longer application life.
Adopt drill hammer to replace existing hobboing cutter, described in each, between drill hammer 1, be provided with sliding support face 2, in mutually supporting, back and forth hit rock stratum, the cutting force that drill bit self rotation produces, the impact force of impulse drive means generation and the extruding force of stake hole surrounding are weakened, extend the life cycle of drill hammer, the ladder platform of drill hammer can make bore diameter produce alternately variation 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 to this, any be familiar with those skilled in the art the present invention disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in 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.
