Product Description

Product Description

The rope core drilling rig is an important equipment in the field of geological exploration, and its core advantage lies in the ability to obtain rock cores without lifting the drill, greatly improving drilling efficiency and reducing costs. This drilling rig quickly extracts the inner tube containing rock cores from the drill rod through a steel wire rope, avoiding the tedious process of repeated tripping and drilling, especially suitable for deep hole drilling. Equipment usually consists of a host, power system, hoisting device, etc. It has the characteristics of high automation and stable core recovery rate, and can operate under complex geological conditions. It is widely used in mineral resource exploration, hydrogeological survey and other scenarios. Its technological development integrates mechanical transmission and hydraulic control, and in recent years, intelligent upgrades have further optimized operational convenience and data monitoring functions, becoming one of the key equipment for modern geological drilling.

Our Advantage

1. Full hydraulic control is convenient and flexible

It can adjust the speed, torque, propulsion axial pressure, anti-axial pressure, propulsion speed, lifting speed of the drilling rig at any time, as well as the stylized experience value rig parameter matching program. To meet the needs of different drilling tool operating conditions and different construction technologies.

 

2. Top drive rotary propulsion lift

Top drive power head has anti-impact design patented technology, rotary gear reducer reliable and durable, direct access to the drill pipe, shorten the auxiliary time, but also conducive to pipe drilling.

 

3. Multifunctional drilling

Various drilling processes can be used on this drilling rig, such as: down-the-hole drilling, through-air reverse circulation drilling, gas lift reverse circulation drilling, cutting drilling, roller cone drilling, heel drilling and core drilling, etc. The drilling rig can be equipped with mud pumps, foam pumps, generators or sampling equipment according to user requests. The drilling rig also comes standard with various winches.

 

5. High work efficiency

All kinds of centering devices, rod feeding mechanisms, rod unloaders, lifters, anti-sludge one-way check valves, centralizers, low-temperature start-ups, specialized air filters, etc., are suitable for various drilling processes and the requirements of different use environments. They are easy to control and flexible, with fast drilling speed and short auxiliary time. Therefore, the operation efficiency is high and the risk of construction accidents is reduced.

 

6. High outright crawler

The high outriggers are easy to load and transport, and can be loaded directly without a crane. Tracked walking is more suitable for muddy on-site movement.

 

7. Unique Adjustment of Positive and Negative Axial Pressure for Full Hydraulic Drilling Rig

All kinds of impactors want to achieve higher impact efficiency have their matching better axial pressure and speed. During the drilling process, with the increasing number of drill pipes, the axial pressure on the impactor is also increasing. Therefore, during construction, the positive and negative axial pressure valves are adjusted to ensure that the impactor can obtain a more matching axial pressure. At this time, the impact efficiency is higher.

 

8. Efficient and durable oil mist dispensers and pumps

During the drilling process, the high-speed impactor is lubricated at all times to extend its service life to the greatest extent.
