KY系列钻孔机是地基与基础处理设备，适用于CFG、CFA，工法、灌注桩、软基加固等多种基础施工，是近几年来发展起来的一种复合地基处理新技术，已列为国家级新工法和国家施工规范。
我公司生产的KY系列钻机具有如下特点：
1、 钻机采用长螺旋成孔，可通过钻杆中心管将混凝土(或泥浆)注入孔底。即能钻孔成桩由一机一次完成，也可用地干法成孔，注浆置换等多种工法。
2、 动力头采用双电机驱动、大中心通孔的减速机，承载、过载能力强，结构紧凑，噪音低，寿命长，是目前国内打桩机最理想的动力装置。
3、 桩架为液压步履式结构，可自行起落臂架，行走、回转、对位准确、可靠，施工效率高，劳动强度低。
4、 钻机采用拖运与装运结合的方式，整体性强，场地转移方便，使用费用低。
5、 整体的电气、液压、操纵、监视仪表均集中在司机室内，司钻人员操作方便、简单。
液压系统
包括油泵电机总成、邮箱、支腿油缸、行走油缸、斜撑油缸、油管、阀件等。液压系统均安装在底盘上，控制集中在司机室内。
钻杆、钻头
本机采用螺旋式钻杆，为法兰连接方式。钻杆底部的钻头设有活门，防止泥沙进入中心管内。压注混凝土(或泥浆)可自行打开。
动力头
由两个风冷电机、减速机、弯头、提升架和滑块组成，工作时两个电机通过联轴器带动减速器的高速轴旋转，将动力传给低速轴，低速轴通过法兰带动钻杆作旋转运动，低速轴为中空轴，上端设有密封装置与弯管接通。
行走机构采用电动履带式和步履带式，移动方便、施工效率高、电机故障率低、维修费用大大减少。电履带式桩机履带接地长从2.8M～5M,而步履带式桩机步履每步行走1.2M～2M的范围，给施工带来很大的便利。
施工过程中辅以油缸支腿，使桩机更加稳固可靠，不会发生侧倾翻机事故步履带式和电履带式长螺旋桩机配置不同的油缸支腿以方便施工。
电控系统设计先进、合理、可靠。采用国际知名品牌的电器元件性能稳定、可靠，并且采用有线控制方式，减少指挥人员。操作机手可自己找准桩位。
回转机构可使桩架进行360°回转， 两个斜撑调整机构可独立动作，实现桩驾立
选用大型机座的减速机，使用中不易损坏。 柱垂直度的调整。
Electromotor Bore Piling Machine
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.
Hydraulic System
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.
Power Head
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.
