Description
Technical field
The present invention relates to field of mechanical technique, particularly a kind of drilling bucket that is used for piling machinery.The invention still further relates to a kind of piling machinery that comprises above-mentioned drilling bucket.
Background technology
Along with the fast development of China's economic construction, market increases day by day for the demand of various piling machinerys.
The work progress of modern construction engineering generally all begins with pile foundation construction, therefore, it is particularly important that pile hole construction seems, with the rotary drilling rig is example, in the work progress of rotary drilling rig, and can be according to the difference of the geological conditions that runs into, select to use various drilling tool, for example various drill bits or drilling bucket etc., rotary drilling rig need the boring mud in its drilling bucket is derived after creeping into a period of time, and need open drilling bucket this moment.
Please refer to Fig. 1, Fig. 1 is a kind of structural representation of typical rotary drilling rig.
The typical rotary drilling rig of this kind comprises equipment 11, equipment 11 hauls drilling rod 12, and drives and to carry on the drilling rod 12 or descend, and the rotation of drilling rod 12 and creeping into by unit head 14 drives, pressurization oil cylinder 13 drives the rising and the decline of unit head, and the end of drilling rod 12 is equipped with drilling bucket 15.Drilling bucket 15 is to use one of comparatively frequent drilling tool in the rotary drilling rig, it is a kind of drilling and forming hole device, cylindrical substantially straight tube of the profile of drilling bucket 15 or taper, it bores the end and can open fully, on the bottom cutting teeth and sluice gate are arranged, the soil that will cut when rotary drilling is considered to be worth doing in the bucket of packing into, can all take the soil bits out of bored hole after filling in the bucket, and the soil that will get out bits are from the bottom discharge of drilling bucket.When the soil bits under drilling bucket 15 is drilled fill up, rotary drilling rig need be outwelled soil, at this moment, equipment 11 will be carried on drilling rod 12 and the drilling bucket 15 earlier, forwards down the position of soil then to by revolution, and pressurization oil cylinder 13 presses down unit head 14, be provided with push rod between at the bottom of the release platen of unit head 14 and the brill of drilling bucket 15, one side of boring the end and drill body is hinged, and push rod moves downward and promotes hook lock with unit head 14 and opens drilling bucket, and the soil bits are poured out; And when drilling bucket is closed, rotary drilling rig need return back to suitable position (slope position that for example has the suitable gradient), 14 orders of rotational power head are bored the opening at the end and are in suitable position (position that for example deviates from the slope), equipment 11 is transferred drilling rod 12 and drilling bucket 15 then, provide impulse force upwards at the bottom of giving the brill of drilling bucket 15, and the hook lock that bores between end and the drill body by the order of this impulse force catches on, and closes thereby drive drilling bucket.
In above-mentioned rotary drilling rig, the unlatching of drilling bucket realizes by catch bar, because the power end of catch bar is far away with the distance of boring the end, this just requires the external diameter of catch bar enough big, has higher flexural strength to guarantee it, and the external diameter of catch bar is bigger, it is promptly bigger in the inner occupation space of drilling bucket, thereby influences the smooth degree that sand enters drilling bucket inside, and the utilization rate of steel is also very low simultaneously, if sand contains bigger sillar, may make then that depression bar is stuck can't to move; And if the external diameter of catch bar is less, can cause the catch bar easy deformation again, be easy to damage, the fault rate of drilling bucket is higher, and job stability is lower.
Therefore, how to improve the operating efficiency of drilling bucket switch, reduce its fault rate, improve job stability, just become the problem that those skilled in the art need solve.
Summary of the invention
