XY-44 Core Drilling Rig

 

1.General

XY-44A Core Drill, a new type of product with enhanced capa city, is a kind of hydraulic-driven, spindle, diamond-bit, small-diameter core drill with fairly powerful drilling force. It is mainly s uitable for exploration of metal or non-metal solid mineral ore bed. It is widely a pplied in core drill with diamond bit or hard tungsten-carbide-tipped bit and diamond bit in the field of geology, metallurgy, coal mine, hydrological and engineering drilling. It can also be used in the fields of superficial-zone petroleum and natural gas mining, mine workings ventilati on and water discharge tunnel drilling as well as founda tion pile construction in large diameter. It is in reasonable structure, light weight, powerful capacity, multiuse, steady performance, high responsibility and high standardization and generalization.

 

2. Main Features of XY-44A drill

1. There are more speed grade (8 grades), reasonable speed range and high torque while low speed. Max. torque is up to 8000 N•m . The drill is adapted on core drilling with tungalloy-carbid-tipped and diamond oil as well a s engineering geology exploration, hydrology well drilling and basic pile engineering.

2. With large spindle I.D. 93mm(3.66 inch), the drill is fed with double hydraulic cylinders with much longer stroke up to 600mm(23 .62 inch). With strong technological adaptability, the rig can be a dapted on many field, especially on large diameter drill rod drilling, (upper part coring) extracting core with wire line. Thus it is more effective in i mproving dri lling effici ency with less faulty in hole.

3. With powerful drilling capacity, the rated drilling depth comes up to 1,000m(3 9.37 inch) with 71mm(2.80 inch) wire-line coring drill rod.

4. Light in weight, and in fine dismountability, the rig can be dismantled into ten parts easily, the biggest apparatus is in 300 kg (661.5 lb). The whole drill is in 2300kg, it can be moved easily especially in mountain area.

5. The hydraulic chuck adopts one-way oil supply, with large clamping force and stable clamping.

6. Equipped with a water brake for steady and smooth deep hole drilling .

7. Supplying oil with a simplex gear pump, it is easy for installation and operation; lower in energy consumption and in low oil temperature of hydraulic system; the rig is for sure in steady drilling. The hand-operated oil pump can be put in use to hoist the drilling tools in hole upon the power engine failing to operate.

8. With compact structure and reasonable layout, with all components exposed, and with non overlapped ones, it is convenient for maintenance.

9. With low center of gravity and long travelling distance up to 460mm(18.1 inch), the rig is reliable and stable in high speed drilling.

10. It is easy to get to know the conditions in hole with an antivibration meter. Less in operating handles, the rig can be operated credibly and flexibly
