Product introduction of cmm2-8 hydraulic anchor drill truck for coal mine

The cmm2-8 hydraulic anchor drill rig for coal mine (dca-45 type automatic roadway advanced cutting machine) is specially used for the construction of the firework holes.In the technological process of "cutting top and unloading pressure along the empty roadway", the key process is the burst hole in the roadway roof construction, which makes preparation for the burst top in the mining process.The construction of burst holes must meet the requirements of good quality of hole formation, small Angle error of borehole, straight line of all boreholes and parallel of all boreholes.

Main features of cmm2-8 hydraulic anchor drill truck for coal mine

1. Reasonable and compact structure and flexible movement;

2. The equipment is small in size, USES caterpillar track to walk, and has good passability;

3. When locating the slit hole, the operation is simple and the two drill arms work at the same time;

4. Two drill arms can rotate independently, which can meet the requirements of Angle between drill axis and plumb line;When the hydraulic drill truck is on the slope, the adjustment of the drill arm through the swing mechanism can meet the requirements of parallelism of all boreholes. When the roadway conditions are poor, it can avoid the failure of roof due to cross hole, Angle between borehole axis and plumb line, etc.

5. The drill arm has a lateral movement mechanism, which satisfies all bores on a straight line, makes the top plate cutting along the pre-split cutting seam backward to the roadway quality and ensures the roadway width after the roadway leaving, which greatly reduces the maintenance amount of the roadway in the future.

6. The drill rig is equipped with large torque motor and drilling efficiency;

7. The drill rig is equipped with drill pipe clamping mechanism and drill head device, which can facilitate the loading and unloading of drill pipe and the guidance of drill pipe;It is easy to install directional blasting shaped charge pipe.

8. The hydraulic system adopts German brand, variable control, and the system is stable and reliable.
