Description

Super large moment of torsion auger boring pouring pile machine

Technical field

The utility model relates to a kind of super large moment of torsion auger boring pouring pile machine.

Background technology

CN201546613U discloses a kind of long-spiral drilling machine, comprises chassis assembly, and this chassis assembly has walking mechanism and rotary table; This rotary table is provided with boring tower, is equipped with on the boring tower also to be provided with on the said rotary table by motor-driven hydraulic pump along the unit head of boring tower body of the tower lifting moving; Hydraulic motor is installed on the unit head, and the clutch end of hydraulic pump and the power intake of hydraulic motor are in transmission connection, and the clutch end of hydraulic motor and the power intake of unit head are in transmission connection; The moment of torsion of this rig is generally below 100KNm; Because of being subject to moment of torsion, its drilling diameter is limited, and should not be used for hard geology.The rotary drilling rig that industry is generally used, but major diameter pore-forming and hardpan pore-forming, but cost is high and can not realize that the limit is carried and bore the limit perfusion, efficient is not high, and in addition, the situation that under geological conditions such as frozen soil, has pore-forming to cave in is of limited application.

The utility model content

The purpose of the utility model is to overcome the deficiency of above technology, and a kind of major diameter pore-forming and complex geological condition pore-forming, low cost, high efficiency super large moment of torsion auger boring pouring pile machine realized is provided.

The technical scheme of the utility model is: comprise the chassis that is made up of running gear and fuselage; High-power power station, pile frame, auger boring filling system are installed on the chassis; Said auger boring filling system comprises the auger stem of hydraulic motor, reductor, gear-box, band perfusion functional, and auger stem moves up and down along the walking track of pile frame; It is characterized in that said hydraulic motor is two high-torque hydraulic motors; The front end of hydraulic motor is connected with high-power power station; The rear end is connected with reductor; Said reductor is connected with the gear-box that one group of high-strength tooth wheel set constitutes; The auger stem of said band perfusion functional is a wide-angle blade screw drilling rod, and sounding gear, water booster system and clear earthenware also are housed on the auger boring filling system.

Said sounding gear is on main hoisting machine, turn-sensitive device to be housed, and turn-sensitive device is connected with controller, and controller is presented on the display screen of driver's cabin after sensor signal is converted into the degree of depth.

Said water booster system comprises two pulley and two pulleys that are positioned on the boring tower of being positioned on the unit head, and wire rope passes four pulleys respectively, is connected with the pressurization hoist engine.

Said clear earthenware comprises by the gyroaxis of motor driving, is installed in the clear native bar on the gyroaxis, and clear native bar wraparound rotating shaft is rotated and extend in the middle of the helical blade of wide-angle blade screw drilling rod under motor drives; Clear earthenware is fixed on the fuselage through link.

The utility model and prior art are relatively; The moment of torsion of rig is more than doubled, and can reach the super large moment of torsion of 200KNm, can satisfy the pore-forming problem of major diameter pore-forming and complicated geologicals such as hardpan, frozen soil layer, but the perfusion of brill limit is proposed on the limit, and cost is low, and efficient is high; Widened range of application greatly.
