Description
Technical field
The utility model belongs to technical field of buildings, is related to a kind of drilling rod, more particularly to a kind of power underneath type drilling rod
Material conveying pipe mechanism.
Background technology
At present, the piling machinery for being used on construction site has two kinds：A kind of swivelling pile driver, the structure of this piling machine
It is, using the drilling rod hanger bracket of hoist engine pull-up, pile driving equipment of the rod bit to drifter drill for underground pore-forming to be driven by unit head；
Another kind is jump bit piling machine, and the structure of this piling machine is fallen repeatedly using hoist engine pull-up jump bit, and lifting comes real
Now drive piles.Wherein, swivelling pile driver mainly realizes the purpose to underground drilling rod in piling by circumferentially rotating for drilling rod,
Drilling rod is lowered the temperature and cementing operations are carried out to drilling rod using grouting while drilling rod drills, common grouting is mainly led to
The grout hole for crossing drill rod end is whitewashed, when drilling rod gets into certain depth, it is necessary to drilling rod supernumerary segment, extend drilling rod,
Drill down can be continued.In cementing operations, it is typically employed in and docks drilling rod and extension bar, connect grouting channel, realizes filling
Slurry.
Chinese patent literature discloses a kind of bored concrete pile screw lifting slurry-mud drilling rod [application number：201410263015.7],
It includes one section or some sections of hollow drills and coupled tool joint, and spiral is provided with the outer surface of hollow drill
Connected with tool joint between blade, every section of hollow drill of every section of hollow drill, first segment hollow drill sets with the junction of drill bit
Put mouth spray.Generally, the helical blade is welded on core drilling, and is arranged on the hypomere of hollow drill, the length of helical blade
The 1/4-1/2 of the total length for hollow drill is spent, diameter of its diameter less than drill bit.Helical blade is square with drilling rod in construction
To rotation, upward lifting force is produced to clod in the mud and mud of stake holes hypomere etc., while being produced to drilling rod downward
Propulsive force.The program carries out slurry conveying using hollow drill, and when hollow drill has more piece, the length of drilling rod drives
The power of drilling rod cannot ensure the perpendicularity of length drilling rod more long, and because many drilling rods and drill bit synchronous axial system are, it is necessary to carry
The driving force for supplying drilling rod is larger, and energy consumption is also larger.
Based on the reason for above-mentioned, people start to develop the underlying churn of power, such as Chinese patent literature by constantly exploration
Disclose a kind of flexible mixing pile machine [application number of power underneath type：201620193119.X], including stake frame, along stake frame
The sliding platform for moving up and down, the chassis for being arranged on a frame lower, the water swivel above sliding platform and positioned at cunning
The square telescopic drill rod that moving platform lower section is connected with water swivel, is provided with spur reduction case and motor, spur reduction on chassis
The axis hole of the driving gear of case is circular hole, and the axis hole of driven gear is square hole, and motor shaft is inserted into circular hole, drives driving gear
Rotation, inserts square telescopic drill rod in square hole, square hole coordinates with the outermost layer drilling rod of square telescopic drill rod into gap, makes square stretching
Contracting drilling rod can be moved up and down along square hole and can rotated as driven gear is rotated.Under the whole stake machine center of gravity of such scheme
Move, stake frame and chassis overall weight are light, reduce cost, and simple structure is more stable, safer, easy to maintenance.But, should
Scheme does not disclose how the conduit assembly for making telescopic drill rod realize grouting, it is clear that cannot realize in drilling rod telescopic process yet
Realize whitewashing.
