Background technology
Pile driver is the important construction equipments of large foundation engineering the drilling construction such as railway, highway, bridge, coalmine ventilation well, port and pier and highrise building.Existing pile driver is when beating large-caliber pile with dark stake, and owing to the drilling tool diameter is bigger, the moment of torsion that therefore produces is just bigger, to such an extent as to hold so very much the application life of the damage reduction rig that causes equipment; In addition, when playing dark stake, the guide rod that connects bucket can be long, and guide rod is long can to produce bigger energy loss, and operation, transition are all inconvenient, and efficiency of construction is low.
The utility model content
The utility model technical problem to be solved provides a kind of large-caliber pile and shield of dark stake of being applicable to and digs formula pile driver power drill bit.
For solving the problems of the technologies described above, the utility model is realized as follows: the described shield of the utility model digs formula pile driver power drill bit and is made up of column type housing, control electromagnetic valve, motor, hydraulic oil container, hydraulic oil pump, hydraulic power head, hydraulic oil pipe, drilling rod, vertical power-assisted hydraulic jack, transversal stretching hydraulic pressure fixed oil cylinder; Motor is installed in the column type housing; Motor output shaft is connected with hydraulic oil pump; Hydraulic oil pump is communicated with hydraulic oil container; The hydraulic oil container oil-out is equipped with control electromagnetic valve, and the hydraulic oil in the hydraulic oil container is connected to hydraulic power head through hydraulic oil pipe and drives hydraulic power head rotation, the closure of control electromagnetic valve control oil channel and the flow direction; Drilling rod is installed on the hydraulic power head, and bucket is installed in the drilling rod bottom; Evenly be installed with four vertical power-assisted hydraulic jacks at column type housing inwall, the movable end of four vertical power-assisted hydraulic jacks is connected with bucket, gives the bucket power-assisted; At column type housing middle part, evenly be installed with four transversal stretching hydraulic pressure fixed oil cylinders, the movable end of four transversal stretching hydraulic pressure fixed oil cylinders withstands the inwall in the hole of driving piles to overhanging Zhi Bingneng.
Be provided with the husky pump line of the mud road of two up/down perforations in the described column type housing, but the crossover-circulating type method construction.
Described column type housing top is provided with assembly pulley, and there is wire rope in system on it.
The good effect of the utility model is: the utility model is very suitable for beating large-caliber pile and dark stake, and the movable end of four vertical power-assisted hydraulic jacks is connected with bucket, thereby gets darker stake can for the bucket power-assisted; The movable end of four transversal stretching hydraulic pressure fixed oil cylinders can withstand the inwall in the hole of driving piles to overhanging, and boring head upper part is fixed in the hole, the moment of torsion that produces when offsetting boring, thus can get large-caliber pile.
