Abstract

The utility model provides the pile driver of an external pipe coil and an inside spin. The main structure includes a borer chassis and the frame work of the pile driver provided with a windlass. The framework is provided with a drill stem motor driven to move up and down by the windlass and a drill stem. The utility model is characterized in that the drill stem is provided with a screw drill vane conveying the soil and the external pipe coil which has a contrary turning direction is arranged outside of the drill stem. The wall of the external pipe coil is provided with a plurality of displacing or feeding mouths. The inner drill stem of the pile driver of the utility model screws into the groundsill soil horizon to form holes and the external pipe coil revolves to follow a protection wall. The rotation of the external coil pipe reduces the friction force of the soil horizon and the outer ring of the bottom of the external coil pipe is installed with an alloy tool bit which can cut the soil horizon to reduce the following resistance of the external pipe coil; therefore the depth of the holes can be ensured. In practical application, the pile driver of the utility model has the advantages of credible quality, simple construction, less noise, high automation degree and convenient control, which has a wide industrial extension foreground.

Description

Outer coil inside spin pile forming machine
Technical field
The utility model relates to a kind of outer coil inside spin pile forming machine, belongs to the construction machine technical field.
Background technology
The main reinforcing technique that adopts is a concrete pile in ground is handled, its construction long auger technology that adopt more.Under project site soil layer situation complicated situation, long spiral pore-forming tends to collapse hole, shrinkage cavity occur in construction, thereby produces serious quality accident such as undergauge and broken pile when causing pile.In order to overcome foregoing problems, on the basis of spiral pore-forming pile forming machine, developed the pile forming machine of screw shell pore-forming, adopt of domestic screw shell pile forming machine applies the static(al) immersed tube to sleeve pipe more, and it is big that sleeve pipe vertically is pressed into the soil layer resistance; The effective hydraulic-driven of external rotary sleeve, equipment maintenance cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of outer coil inside spin pile forming machine, manages and protects the operating type that wall, inside spin boring precession is discharged cubic metre of earth simultaneously with the opposite outward turning of rotation direction, guarantees pile quality.
The technical solution of the utility model is achieved in that this outer coil inside spin pile forming machine, its basic structure comprises: borer chassis, be provided with and on the pile forming machine frame, frame of hoist engine the drilling rod motor and the drilling rod that are moved up and down by the hoist engine traction be set and constitute, it is characterized in that: drilling rod is provided with the defeated earth boring auger leaf of spiral, drilling rod is provided with the opposite outer coil of rotation direction outward, and the outward turning tube wall is provided with a plurality of casting/charging apertures.
Described outer coil inside spin pile forming machine, the drive motors of described outer coil is arranged on the pivoting support gearbox, and along the axial precession of drilling rod, the mesopore that drilling rod passes pivoting support enters outer coil by the hoist engine traction.
Described outer coil inside spin pile forming machine, described outer coil bottom outer shroud is installed alloy cutter head.
Described outer coil inside spin pile forming machine, the drive motors of outer coil is set to 1 or 2.
Described outer coil inside spin pile forming machine, the gear ring of outer coil pivoting support and motor-driven gear engagement.
Described outer coil inside spin pile forming machine, the outward turning pipe flange is connected on the gear ring of pivoting support.
One of innovative point of the utility model pile forming machine is to adopt the opposite precession borehole drill construction of two cover directions, casting pore-forming in the interior drilling rod precession foundation soil, outer coil rotation follow-up retaining wall, because the rotation of outer coil has reduced the frictional force with soil layer, the alloy cutter head that outer in addition coil bottom outer shroud is installed can cut soil layer, reduce the follow-up resistance of outer coil, can guarantee effectively that pore-forming reaches projected depth.Two of innovative point be with pivoting support as outward turning piping support rotating actuator because outer coil and drilling rod all need independently motor-driven rotation, and power is bigger, pivoting support can effectively dwindle the volume of transmission mechanism, the reduction manufacturing cost.
It is reliable that pile forming machine of the present utility model has pile quality in actual applications, and construction is simple, and noise is low, and the automaticity height is convenient to advantages such as control, has wide industry promotion prospect.
