ZDY22000LK Large-Diameter Borehole Crawler Type Drilling Rig

1. Introduction

The ZDY22000LK crawler-type fully hydraulic tunnel drilling rig for coal mines is an integrated high-power remote control drilling rig that can achieve long-distance remote control operation and is suitable for rotary drilling and large-diameter drilling construction. It can be used for coal mine gas drainage drilling construction, and can also be used for various drilling constructions such as underground water exploration and drainage, geological structure and coal seam thickness detection, coal seam water injection, roof and floor grouting, etc. Especially in the large-diameter drilling construction of "replacing tunnels with holes", it has outstanding advantages.

2. Technical Characteristics

1. Wireless remote control operation, convenient observation, and safer construction.

2. The drilling rig has a large rated torque, higher construction efficiency, and the ability to handle accidents in the hole.

3. The new overall flip-type amplitude modulation device has a wide adjustment range and is stable and more reliable.

4. The remote-controlled multi-functional pump truck has a hoisting function, which saves effort when loading and unloading drill pipes; it is equipped with a mud pump system that can meet the drilling needs of different working conditions.

5. It has an electro-hydraulic dual-control single-action operation, which is simple to operate. It is also equipped with a one-button automatic shackle function to improve the efficiency of drilling retraction.

6. Equipped with double-column stabilization and brake locking devices, the construction of large holes has strong stability.
