Product Description

Product Description

The crawler hydraulic DTH drilling rig is mainly a DTH drilling rig developed for quarries, cement mines, open-pit coal mines and other types of mines. It can complete the drilling construction of main blasting holes and pre-cracks. The DTH drilling rig has the characteristics of large drilling diameter, high drilling efficiency and wide adaptability. It is widely used in the production of building materials, coal, metallurgy, chemical industry and other mines. It is also the main equipment in the construction of engineering departments such as geology, construction, hydropower and transportation.

1. The control valves are centrally arranged to facilitate the operation and control of the drilling rig. The system is reliable, simple, and has low maintenance costs.

2. Rapidly advance and enhance operations to reduce auxiliary time and improve efficiency.

3. Strengthen the cooling system to avoid high-temperature shutdowns and ensure reliable performance.

4. Swing track chassis, easy leveling, high ground clearance, good passability and strong mobility.

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.
