when the rocks which do not fall on the side wall of the tunnel are required to be removed, a worker controls the manipulator pitching oil cylinder 31 to stretch and retract through the control platform, so that the manipulator basic arm 3 can be driven to rotate, the danger removing mechanism 4 can be driven to rotate after the manipulator basic arm 3 rotates, then the rocks which do not fall on the side wall of the tunnel can be knocked down, and when the rocks which do not fall on other positions of the tunnel are required to be removed, the worker on the driving seat can control the arch trolley 1 to move in the tunnel;
the danger removing mechanism 4 is arranged on the mechanical telescopic arm, so that workers can remove rocks which do not fall in a tunnel by utilizing the danger removing mechanism 4 in a short distance, meanwhile, as the crushing pick 45 is arranged on the mechanical arm extension arm 32 through the universal coupling 43, the crushing pick 45 can knock down the rocks which do not fall in the tunnel in different directions and at different angles, compared with the mode of manually inserting the rocks into a rock slot, the labor is saved, the situation that when the workers remove the rocks manually, if the workers stand too close, the fallen rocks are not avoided, the damage to the workers can be caused, and meanwhile, if the distance between the workers stand is too far, the longer crow is required, but the force is too long, the risk cannot be completely removed, and the safety of the constructors cannot be guaranteed when the workers stand;
after the removal of the rocks not dropped in the tunnel is completed, the worker pulls out the rectangular pin shaft 42 from the connector 41, and then the danger removing mechanism 4 can be detached.
Another embodiment based on the general embodiment further comprises a protection mechanism 5; the protection mechanism 5 comprises a stop block 51, an annular bin 52, an annular plate 53 and a protection plate 55;
