Bolter Road Header

Bolter-miner is a newly developed multifunctional road header .Many technologies of this machine belong to the new leading and innovative technologies at home al and abroad, which represent the development trend of bolter-miners in China. This n machine is suitable for tunneling of various floors and coal mine roadways with a gra dient ± 16°, also can be used for railway, highway, hydraulic engineering and other tu innel construction.

Technical features:

1、It can make full use of its own weight in the cutting process, with good cutting stability and strong cutting ability;

2、The split high-effciency transport mechanism is adopted. The wear-resisting plate is welded on the outside of the rotary table, and the wear-resisting plate is additionally equipped for the shovel plate. The whole process pressing chain is adopted to improve the wear resistance and reduce the material transportation resistance.

3、The drilling rig system is integrated on both sides of the machine body, and the operation console is placed above the machine body, which solves the shortcomings of blocking the line of sight caused by integrating the roof bolter system on the cutting arm and poor reliability caused by cutting vibration. The drilling rig system and the road header system are electrically and hydraulically interlocked.

4、The left and right drilling rigs are controlled by remote control and manual control,which can realize the full-section rock bolt and anchor cable support of rectangular, arched and trapezoidal tunnels.

5、The drill box adopts a high-speed and high-torque hydraulic motor, and the revolving speed and feed speed of the drill box adopt the stepless speed regulation technology, so as to improve the effciency of rock bolt and anchor cable support and the adaptability of the drilling rig.

6、The support process of rock bolt and anchor cable is fully mechanized, which reduces the labor intensity of workers, improves the safety of operation, avoids the workers from being drenched during diling, reduces noise and improves the working environment of workers.
