The characteristics of KY series bore piling machine
The CFG series drilling machine is a kind of equipment for foundation construction as well as foundation treatment. It fits various kinds of foundation constructions, like the CFG、CFA， construction method, perfusion method and soft foundation strengthen etc. It's one of the latest technique and treatment for compound foundation construction, and it has been listed as a new state-level construction technique and construction standard.
Our company's KY series drilling machine has the features as below:
1. The drill machine is adopted the long screw to dig the hole and can perfuse concrete into the hole's bottom through the center of drill rod. It can make pile only by one machine in one time, and is suitable for dry method, replacement of infuse and some other construction processes.
2. The power head device is adopted speed reducer with large hole through the center and drove by double-motor, which guarantes the high bearing capacity, compact structure, low noise and long service life. It's the most idealest power device in domestic pile drive field at this present.
3. Hydraulic static moving device is adopted for this pile-driving frame, so that it can raise and down the arm frame automatically, walk, rotary and accurate emplacement and reliably, as well as high efficiency and low strength of labor.
4. Drill rig is adopted the combined way of consignment and shipment, features good integrity, easy to transfer and low expense cost.
5. All the monitoring instruments for electric, hydraulic, and operation are centralized at the driver cab. It's convenient and easy to operate.
The hydraulic system, including a assembly of oil pump motor, oil tank, supporting cylinder, moving cylinder, sprag cylinder, oil tube and valve, etc, are installed on the chassis. The controller centralized in driver cab makes the machine more easy to operate.
Drilling rod and drilling bit
Drilling machine uses screw drilling rod and flange coupling. There is no valve at the bottom of the drilling rod, so that it can stop silt leaking into the center tube. Moreover, the tube can open automatically when concrete or slurry is injected in by force.
The power head consists of two wind cold motors, a speed reducer, an elbow, a pulling yoke, and a sliding block. When working, the two motors revolve the high speed shaft of the speed reducer through their couplings to pass power to the low speed shaft, and then the low speed shaft revolve the drill pipe though its flange. The low speed shaft, being a hollow shaft, connects the syphon through a sealing device.
Electric crawler type and step moving type are adopted for walking mechanism, which brings a good result of convenient movement, high efficiency, low troubleshooting and low maintenance cost. The grounding length of the creeper tread for electric crawcer is 2.8M to 5.0M. The moving strolce for step moving type is 1.2M to 2.0M brining great convenience when the machine working.
Using supporting cylinder during construction process enables drilling machine to be more stable and reliable , and avoids side tumbling accident . What's more, it is equiped different machine to realize the 360° full revolution supporting cylinder on the step moving type and electric crawler type.
Advanced electric controller system is reasonable and reliable. Electronic components come from world-class brands, feature stable and reliable. It is used of wire controller system reduces the amount of commanders. Operators can find the pile position correctly.
Rotating mechanism can realize the 360° full revolution. The speed reducer with large frame makes sure of the less damage.
Two sprag adjusting mechanism can work independently and adjust the perpendicularity of the pile holder successfully.
