Abstract
The utility model discloses a square hole forming machine for a cast-in-situ bored pile. The square hole forming machine comprises a guide body shell and a spiral worm arranged in the guide body shell, the lower end of the guide body shell is provided with a wear-proof blade, the top end of the guide body shell is provided with a wing plate, and the top end of the spiral worm is provided with a drill rod penetrating out of the wing plate. When the square hole forming machine for the cast-in-situ bored pile works, the spiral worm moves forwards in a spiral mode, the spiral worm is connected with the drill rod to conduct rotating construction, a round hole is formed, the self-gravity of the drill rod and stress of a power head are transmitted to the wear-proof blade, the wear-proof blade cuts in a stratum with the middle part with the cut round hole, and meanwhile the spiral worm conducts rotation operation to take out soil, so that wall repairing and forming of a square pile hole are completed, construction difficulties are reduced, and construction efficiency is improved.
Description
Technical field
The utility model relates to a kind of drilling pouring pile hole machine, is specifically related to a kind of bored pile square opening hole forming machine.
Background technology
Rotary drilling rig is a kind of stake construction equipment for pore-forming operation, and the advantages such as along with greatly developing of domestic Foundation Design in recent years, rotary drilling rig is efficient, quick with it, environmental protection, hole quality height are widely used.It mainly utilizes unit head to drive drilling rod, and by drilling rod, the driving force of unit head and plus-pressure is passed to drill bit and realizes the cutting on stratum and creep into.At present, on market, rotary drilling rig pore-forming is circle, is mainly used in the construction in cylinder pile hole.In China, oneself starts to be applied to Practical Project to barrette gradually, and with respect to circular stake, barrette is identical at sectional area is the side friction area that has greatly increased stake in same material consumption situation, has improved the side-friction force of stake, can increase substantially the bearing capacity of stake.In the time that rotary drilling rig user runs into barrette engineering, existing drilling bit of rotary-digging drilling rig is difficult to meet instructions for use.
In long-term use practice, it is found that circular cross section drilled pile bending resistance is little, mechanical property is poor.If in the situation that dowel section area is constant, changing geometry is square or rectangle as changed circular, increase moment of inertia, just can greatly change the mechanical property of stake, particularly greatly improve the Its ultimate bearing capacity of stake, pile shaft material intensity is not fully exerted, and the Rectangular Section Pile that the concrete of equivalent is made have larger friction area than circular cross-section stake.Can make like this pile foundation function more perfect, the scope of application is more extensive.
Utility model content
The purpose of this utility model is to provide a kind of bored pile square opening hole forming machine, has reduced difficulty of construction.
For achieving the above object, the present invention is achieved through the following technical solutions: comprise the guide way shell of both ends open and be arranged at the helical worm in guide way shell, the lower end of guide way shell is provided with wearing blade, the top of guide way shell is provided with wing plate, on helical worm, top is provided with drilling rod, and drilling rod passes wing plate.
The arranged outside of described drilling rod has square guide peg.
Between described drilling rod and square guide peg, be connected by bearing.
Described drilling rod is connected with the power set for power is provided.
Between described guide way shell and wing plate, pass through bearing pin pin joint.
Described guide way shell is square structure.
Described wing plate is cross wing plate.
Described wearing blade is secured by bolts on guide way shell.
Described square guide peg is fixed by welding on wing plate.
Compared with prior art, the beneficial effect the utlity model has: the utility model by arranging helical worm in guide way shell, the lower end of guide way shell arranges wearing blade, the top of guide way shell arranges wing plate, on helical worm, top arranges drilling rod, when work, helical worm rotation is advanced, worm screw is connected rotation construction with the inner rotatable portion of drilling rod, get circular hole, then the deadweight of drilling rod and the plus-pressure of unit head are passed on wearing blade, the stratum that wearing blade has cut into circular hole to mid portion is cut, helical worm rotary operation is taken earth out of simultaneously, thereby the wall of repairing that completes barrette hole is shaped, reduce difficulty of construction, improve efficiency of construction.
Further; the utility model guide way shell plays guide effect in the time creeping into and carry brill, guarantees straight line construction, and prevents that the square drill bit of rotary drilling rig from snapping in the hole wall in barrette hole while upwards lifting; effectively protection drill main body is not worn, and extends the application life of the square drill bit of rotary drilling rig.
In the utility model, drilling rod adopts bearing to be connected with square guide peg, ensures that the guide way shell outside helical worm drill bit is not moved, rotates, and guarantees straight ahead.
In the utility model, guide way shell adopts bearing pin to be pinned on wing plate, and wing plate center is welded on square guide peg, ensures not to be offset in work progress king-pile hole, has reached plant equipment convenient disassembly simultaneously.
Between wearing blade in the utility model and guide way shell, coordinate by bolt, facilitate the replacing of wearing blade.
Brief description of the drawings
Fig. 1 device schematic diagram of the present utility model.
Fig. 2 device top view of the present utility model.
Wherein, 1 is helical worm, and 2 is guide way, and 3 is wearing blade, and 4 is bolt, and 5 is drilling rod, and 6 is square guide peg, and 7 is bearing, and 8 is wing plate, and 9 is bearing pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Referring to Fig. 1 and Fig. 2, the utility model comprises the guide way shell 2 of both ends open and is arranged at the helical worm 1 in guide way shell 2, the lower end of guide way shell 2 is provided with wearing blade 3, and wearing blade 3 is fixed on guide way shell 2 by bolt 4, the top of guide way shell 2 is provided with cross wing plate 8, passes through bearing pin 9 pin joints between guide way shell and wing plate 8; On helical worm 1, top is provided with drilling rod 5, drilling rod 5 passes wing plate and is connected with the extraneous power set for power is provided, the arranged outside of described drilling rod 5 has square guide peg 6, square guide peg 6 wraps up drilling rod 5 but do not contact, between square guide peg 6 and drilling rod 5, connect by bearing 7, the guide way shell that ensures helical worm drill bit outside is not moved, rotates, and guarantees straight ahead.Between wearing blade 3 in the utility model and guide way shell 2, coordinate by bolt, facilitate the replacing of wearing blade.Guide way shell is square structure, and the Plate Welding high by scuff resistance is formed by connecting.Guide way shell plays guide effect in the time creeping into and carry brill, guarantees straight line construction, and prevents bit freezing, protection drill bit.Guide way shell adopts bearing pin to be pinned at wing plate one end, and the other end of wing plate is welded on the square guide peg of drilling rod outside, ensures not to be offset in work progress king-pile hole, has reached plant equipment convenient disassembly simultaneously.
