Description
Technical field
The utility model relates to piling machinery field, specifically a kind of Novel spiral rig.
Background technology
Along with national basis build development, stake machine and drilling machine market flourishing gradually, long-spiral drilling machine and rotary drilling rig have occupied certain field separately, and rotary drilling rig is mainly used in brill, the filling of large aperture concrete stake.But cost is very high, and when running into some loose soil properties, be also difficult to ensure pouring quality.Long-spiral drilling machine is generally used for the less boring in aperture, fills with stake.Because its motivation transfer motion part of existing spiral drilling machine is all placed in drilling rod top, therefore less stable, overturn accident is of common occurrence.Especially run into aperture larger time, long-spiral drilling machine is often difficult to satisfy the demands.So in piling machinery field, should have a kind of can partly replace revolving dig and novel Novel spiral rig with low cost again.
Utility model content
The purpose of this utility model is for providing a kind of novel Novel spiral rig, to fill up domestic and international blank, meets the many-sided selection demand of user.
The utility model is achieved through the following technical solutions: a kind of Novel spiral rig, comprising frame, rack-mounted mast, being connected on mast and the auger stem that can slide up and down along mast and the power set for driving auger stem to rotate; Power set are fixed in mast foot or frame, and auger stem is by the assembly pulley of mast top, rope hoisting or decline; Described power set are positioned at the bottom of described auger stem, power set comprise base, the fairlead be enclosed within auger stem, for the pivoting support that supports and drive fairlead to rotate and the one or more reductors for driving pivoting support to rotate; Described fairlead inner surface is fixed with the single or multiple length axial arranged along fairlead and is good for, and the vane edge of described auger stem has the single or multiple keyway axial arranged along auger stem, ensures that long strong cooperation inserts in keyway; Fairlead external surface is fixedly connected with the external toothing of pivoting support, and the inner ring of pivoting support is fixed on described base; Described reductor is arranged on base, and reductor is engaged with the external toothing of pivoting support by gear.
It is further: above power set, be fixed with one piece of swash plate.
Reductor is driven by motor or hydraulic motor.
Reductor drives fairlead to rotate by gear and pivoting support external toothing, fairlead drives auger stem to rotate by the keyway on long key and auger stem vane edge, auger stem also creeps into downwards at the Action of Gravity Field of self, can be free to slide between fairlead and vane, when promoting auger stem, can be realized by mast top sheave group with the hoist engine in frame.
The utility model has the advantages that: (1) power set are positioned at auger stem lower end, can increase complete machine stability, reduce overturn accident, and suitably can reduce the requirement of strength of mast, save material cost.
(2) be applicable to bore Large Diameter Pile Holes, ensure can directly pour into when the loose easy landslide of soil property, one-shot forming, ensure to fill with quality of pile.
(3) with the competition of rotary drilling rig, can give user one multinomial selection, and when creeping into same equal aperture, reduce costs.

Detailed description of the invention
Be below a specific embodiment of the present invention, existing the present invention will be further described by reference to the accompanying drawings.
As shown in Figure 1, mast 2 lower end is hinged in frame 1, is connected with for propping up the support bar with fixed mast 2 between mast 2 and frame 1; Mast 2 upper end is provided with assembly pulley 8, assembly pulley 8 is full of stay cord 9, and stay cord 9 one end is connected to auger stem 3 top, and stay cord 9 other end is connected with hoist engine, and hoist engine is arranged in frame 1; Auger stem 3 is connected on mast 2 and also can slides up and down along mast 2, and the lower end of auger stem 3 is connected with power set.
As shown in Figures 2 to 4, power set comprise base 11, the fairlead 4 be enclosed within auger stem 3, for supporting and drive pivoting support that fairlead 4 rotates and two reductors 6 for driving pivoting support to rotate, reductor 6 is driven by motor 7; Fairlead 4 upper end is in the bell mouth shape outwards expanded, fairlead 4 inner surface is fixed with the single or multiple length axial arranged along fairlead 4 and is good for 4-1, the vane edge of auger stem 3 has the single or multiple keyway 3-1 axial arranged along auger stem 3, ensures that long strong 4-1 coordinates and inserts in keyway 3-1; Fairlead 4 external surface is fixedly connected with the external toothing 5-1 of pivoting support, and the inner ring 5-2 of pivoting support installs on the pedestal 11, and base 11 is fixedly connected with mast 2; Reductor 6 is installed on the pedestal 11, and reductor 6 is engaged with the external toothing 5-1 of pivoting support by gear 6-1, and reductor 6 is driven by the motor 7 installed on the pedestal 11.Above power set, be fixed with one piece of swash plate 8, swash plate 8 both sides are separately fixed on mast 2 and base 11, and the soil fallen down when auger stem promotes is slipped on the ground by swash plate 8.
During use, motor 7 drives reductor 6, reductor 6 drives fairlead 4 by the external toothing 5-1 of gear 6-1 and pivoting support, and fairlead 4 drives auger stem 3 by long strong 4-1 and keyway 3-1, then under the Action of Gravity Field of auger stem 3 self, auger stem is crept into downwards.Can be free to slide between fairlead and vane, when promoting auger stem, can be realized by mast top sheave group with the hoist engine in frame.
