Leg type jumbolter, guide rail type jumbolter, airborne jumbolter, etc. With the progress of mechanization and hydraulic technology, the anchor rod installation device is highly mechanized and develops towards automation, and compared with a manually held leg type anchor rod drilling machine, the large-scale machine-mounted anchor rod drilling machine has stronger output thrust, rotating speed and torque and higher spatial mechanism freedom, so that the influence of installation parameters (thrust, torque, installation angle and the like) on the anchor rod anchoring quality cannot be ignored. With the application of mechanical equipment in the field of mining, the mining mechanization degree is continuously improved by the application of high-automation-degree coal mining equipment, however, the fully mechanized excavation mechanization development lags behind the mining mechanization degree relatively, the labor is intensive in the mine roadway excavation and support construction, casualties and mining and replacement tension are easily caused, and the development of 'people reduction and efficiency improvement' and 'intelligent unmanned' development in the coal industry of China are severely restricted. In the aspects of improving the coal roadway tunneling speed and coordinating the contradiction of tunneling, the tunneling and anchoring unit developed abroad can realize the parallel operation of tunneling and installing anchor rod supports. The development of anchor rod installation machinery in China is late, and related technologies are gradually improved.
Most anchor rod anchoring quality detection technologies do not consider the influence of the installation parameters of anchor rod installation instruments on the anchor rod anchoring effect, and the detection result is obviously not suitable for detecting the anchoring effect of the anchor rod installed by a large-scale airborne anchor rod drilling machine. On the other hand, the detection result has no practical significance for guiding and feeding back the optimized design of the installation of the large-scale airborne jumbolter.
