Introduction

1.size：7,370x2,360x2,560mm and 6050kg

2.Application: crawler rock drilling rig is used for drilling blasting blast holes and is suitable for medium and small-sized mines. The drilling diameter range is 80-250mm. It has the function of efficient rock drilling, enhancing the convenience of movement and the safety of operation. Large mining rock drill, but DTH drill rig has advantages in flexibility. Solve the rotating drill in hard rock pile foundation engineering > 80 mpa compressive strength, hard rock drilling difficult problems through "DTH hammer + spin dig diamonds" combination process to improve efficiency. Modified spin exploration hole hammer can be used in high-rise buildings, such as high speed rail bridge rock-socketed pile construction, break through the complex formation limit.

3.Ability: Professional R&D capability, capable of making reasonable modifications based on different customer demands.

Details

Crawler rock drilling rig to cater to the market demand the development of a new type of DTH drill rig, the excellent product performance, flexible operation, complete function, adaptability, has high cost performance.

Crawler rock drilling rig is a rotary impact drilling rig. Its core feature lies in that the impactor directly penetrates to the bottom of the hole to break the rock, with low energy transmission loss and significantly higher drilling efficiency than traditional rotary drilling RIGS. It is mainly used in scenarios such as open-pit mine blasting holes, pile foundation engineering, and slope support, featuring efficient rock breaking and strong terrain adaptability.

1. Core components impact: into the bottom of the hole to produce high-frequency impact, direct effects on rock (pneumatic). Slewing mechanism: drive drill pipe rotation, cooperate with impact implementation shear breakage (power motor/motor). Propulsion system: hydraulic or cylinder with axial pressure, to ensure continuous contact bit crack.

Dust collection device: Two-stage dry filter core system, with a filtration area of up to 18 square meters and a dust removal efficiency of over 85%.

2. The working process of compressed air (or hydraulic) driven shock - bit high-frequency rock.

Uses

Crawler rock drilling rig can be widely applied to rock drilling operations in various projects such as open-pit mining, construction foundation control, water conservancy, power station transportation and national defense construction. It can also be used to drill anchor holes, geological pressure measurement holes and drainage holes and other rock holes for practical purposes. It is also widely used in anchor bolt support. Drilling operations for channel excavation and sewer projects.

FAQ

Q: How to adjust the drilling parameters of crawler rock drilling rig?

A: Hard rock: need to increase the air pressure to more than 0.7 MPa, cooperate with high volume (such as after 30 m/min), promote efficiency of rock fragmentation; Soft stratum: reduce the axial compression and fill in the yellow wall, prevent the hole collapse.

Q: When opening impacter could not be started:

bit by rock dust buried or hole water excessive exhaust resistance increased. Processing: ascension is 20 to 30 cm, reducing resistance after slow down; If it is ineffective, disassemble and clean the valve plate or the debris in the cylinder

Equipment maintenance?

A: Daily check the dust filter clogging situation (filter area 18 ㎡ or higher); Regularly verify crawler tensioning oil cylinder pressure risk.
