Description
Technical field
The present invention relates to piling machinery technical field, particularly relate to a kind of deep-hole spiral pile driver.
Background technology
Screw pile driver is a kind of by the pile driving equipment of unit head drive drill rod assemblies to drifter drill for underground pore-forming, screw pile driver can be divided into two parts: frame and drill rod assemblies, frame is provided with hoist engine, rack for rods, drill rod assemblies comprises motor, reductor, reductor is connected with drilling rod, and drill bit is installed in drilling rod lower end, and drilling rod vertically can slide up and down along the slide rail on rack for rods, steel strand on hoist engine are connected with drill rod assemblies top, thus can control the lifting of drilling rod.During use, open motor, driven by motor drilling rod rotates, the expansion of steel strand is controlled by hoist engine, drill rod assemblies glides along slide rail, drill bit and earth surface also pierce in earth, thus get out stake holes on the ground, then by hoist engine, steel strand are drawn in, thus drill rod assemblies is pulled out in stake holes together with earth, go up in this wise and just define stake holes, but some stake holes need beat very dark, it is very dark that drilling rod inserts earth, some caking of earth in stake holes, and clod is larger, when drilling rod is extracted, resistance is very large, need drawing repeatedly just can extract, reduce the efficiency of pile hole, the load that drive motors on hoist engine is subject to is very large, drive motors is in overburden work for a long time, the application life of serious reduction hoist engine.
Summary of the invention
The present invention is in order to solve the aforementioned problems in the prior, provide a kind of resistance that effectively can reduce drilling rod and extract in stake holes, improve pile hole efficiency, reduce the load of drive motors in hoist engine simultaneously, improve the deep-hole spiral pile driver in hoist engine application life.
To achieve these goals, the present invention adopts following technical scheme:
A kind of deep-hole spiral pile driver, comprise frame, be located at the drill rod rack of frame one end, be located at the drill rod assemblies on drill rod rack, drill rod rack is provided with slide rail, described drill rod assemblies and slide rail are slidably connected, described frame is also provided with the hoist engine driving drill rod assemblies lifting, described drill rod assemblies comprises drilling rod, be located at the drill bit of drilling rod lower end, the outside of drilling rod is provided with principal screw blade, the position of outside between principal screw primary blades of drilling rod is provided with auxiliary helical blade, the rotation direction of described auxiliary helical blade is identical with the rotation direction of principal screw blade, the external diameter of auxiliary helical blade is less than the external diameter of principal screw blade, described principal screw blade, the edge of auxiliary helical blade is provided with sawtooth sword, the upper end of described drilling rod is provided with electric machine support, motor is provided with in electric machine support, reductor, coaxially be connected between the upper end of described drilling rod and the output shaft of reductor.When beating dark stake holes, drilling rod pierces in earth, the sawtooth sword at the edge of principal screw blade, auxiliary helical blade can shred the earth of bulk, some plant roots and stems chopping in earth, thus can also make the long-pending reduction of the earth block in stake holes, thus reduce the resistance that stake holes extracted by drilling rod, namely reduce the load of drive motors in hoist engine, effectively extend the application life of hoist engine on the one hand, on the other hand because earth resistance is little, drilling rod is extracted convenient, improves the efficiency of pile hole.
As preferably, the top of described electric machine support is provided with connecting ring, described drill rod rack top is provided with crossbeam, crossbeam is provided with pulley, pulley is provided with the hook be connected with connecting ring, cable wire on hoist engine is walked around pulley and is fixedly connected with crossbeam, and the side of electric machine support is provided with the slide block be connected with slide rail.Connecting ring is connected by the cable wire of pulley with the hoist engine in frame, and slide block is connected with the slide rail on drill rod rack, is convenient to vertically slide up and down.
As preferably, the lower end of described electric machine support is provided with the drilling rod adapter sleeve of opening upwards, the position that the upper end of described drilling rod is positioned at drilling rod adapter sleeve is provided with spacing ring, between bottom described spacing ring lower end and drilling rod adapter sleeve, between spacing ring upper end and electric machine support bottom surface, be respectively equipped with thrust bearing, be coaxially connected by spline between the upper end of described drilling rod and the output shaft of reductor.No matter drill-string in compression, tension; active force on drilling rod is all born by thrust bearing; the output shaft of drilling rod and reductor passes through spline joint simultaneously; namely the pulling force on drilling rod, pressure can not pass to the output shaft of reductor; thus reductor is played a protective role; prevent speed reducer output shaft repeatedly under tension, pressure effect cause sealing to decline and leakage of oil, the application life of prolonged deceleration machine.
As preferably, the downside of described crossbeam is provided with for the spacing damping cylinder of electric machine support.Damping cylinder plays buffer limit effect when electric machine support rises to top, the impact of electric machine support to drill rod rack can be reduced, especially in hoist engine wrapup procedure, be out of order in hoist engine, continue after causing electric machine support to top to rise, now the effect of damping cylinder is particularly evident.
As preferably, the lower end of described drilling rod extends to form taper guide peg, and described auxiliary helical blade lower end extends to taper guide peg lateral surface.Time drilling rod lower end just enters in earth, resistance is comparatively large, and taper guide peg, auxiliary helical blade are all to reduce the contact area with earth, and then reduces initial bore hole resistance.
As preferably, the bottom of described frame is provided with wheel, and the rear and front end of described frame is respectively equipped with hydraulic supporting feet.Maneuverability more when wheel makes screw pile driver move, use is, hydraulic supporting feet jack-up, and wheel and ground are departed from.
Therefore, the present invention effectively can reduce the resistance that drilling rod is extracted in stake holes, improves pile hole efficiency, reduces the load of drive motors in hoist engine, improves hoist engine application life.
