Meanwhile, it can be understood that, according to specific use requirements, the contact surfaces of the front frame front top beam 27 and the front frame rear top beam 28 of the supporting front frame 13 and the rear frame top beam 49 of the supporting rear frame 14 with the roadway roof can be set to be in the shapes of planes, arcs, trapezoids and the like according to the shape of the roadway roof so as to adapt to the tunneling roadway roof conditions of different shapes. The pushing mechanism 15 arranged between the rear support 14 and the front support 13 comprises pushing hydraulic cylinders respectively arranged between the front support side box body 24 and the rear support side box body 47 on both sides and between the front support base 23 and the rear support base 46 on both sides, and both ends of each pushing hydraulic cylinder are respectively connected with the corresponding side box body and the corresponding base through pushing hinged lug plates 29.
When the tunneling, supporting and anchoring machine is used, the tunneling temporary support device 2 is installed and arranged in a tunneling working face of a roadway, and the tunneling working device 1 (a fully mechanized tunneling machine or other tunneling equipment), the top anchor rod working device 3 and the side anchor rod working device 4 are arranged in the tunneling working space 19 of the supporting front frame 13 and the supporting rear frame 14. Then, the front frame lifting hydraulic cylinder 25 for supporting the front frame 13 and the rear frame lifting hydraulic cylinder 48 for supporting the rear frame 14 are respectively extended, so that the front frame front top beam 27 and the front frame rear top beam 28 for supporting the front frame 13, and the rear frame top beam 49 (composed of a plurality of groups of rear frame top beam cross beams 50 and rear frame top beam down beams 51 which are arranged in a criss-cross manner) for supporting the rear frame 14 are contacted with the top plate of the heading roadway to form the support for the roadway top plate. Each pushing hydraulic cylinder of the pushing mechanism 15 connected between the front support frame 13 and the rear support frame 14 is in a retracted state.
Then, the tunneling operation device 1 starts tunneling, and when the tunneling operation cuts the area of the top of the roadway rock mass, the front end of the front frame front top beam 27 of the front frame 13 is supported, so that a newly exposed top plate at the front end of the roadway can be supported; and if the front end of the front frame front top beam 27 of the supporting front frame 13 is provided with a front shield mechanism, the front shield mechanism is extended or unfolded, so that the supporting area of a newly exposed top plate at the front end of the roadway is increased. When the tunneling operation device 1 needs to continuously cut forwards, all the front frame lifting hydraulic cylinders 25 for supporting the front frame 13 are retracted, and the front frame front top beam 27 and the front frame rear top beam 28 are temporarily separated from the roadway roof; then, the respective pushing hydraulic cylinders of the pushing mechanism 15 are extended to push the support front frame 13 of the lower frame to move forward. After the supporting front frame 13 moves to the right position, the front frame lifting hydraulic cylinder 25 of the supporting front frame 13 extends out, so that the front frame front top beam 27 and the front frame rear top beam 28 of the supporting front frame 13 are in contact with the newly cut roadway roof to form effective support. Then, the rear frame lifting hydraulic cylinder 48 for supporting the rear frame 14 is retracted, and the rear frame top beam consequent beam 51 of the rear frame top beam 49 is temporarily separated from the roadway roof; thereafter, the respective pushing cylinders of the pushing mechanism 15 are retracted, and the support rear frame 14 pulling the lowering frame is moved forward. After the supporting rear frame 14 moves forward to the right position, the rear frame lifting hydraulic cylinder 48 of the supporting rear frame 14 extends out, so that the rear frame top beam consequent beam 51 of the rear frame top beam 49 of the supporting rear frame 14 is contacted with the roadway roof again to form support, and roadway cutting of the next distance is prepared.
In the process of continuous excavation of the excavation operation device 1, a top anchor rod operation device 3 arranged in the support front frame 13 is used for performing permanent support operation of driving a top anchor rod on a top plate of a newly exposed roadway space in a top anchor operation space 17 reserved at the top of the support front frame 13 and behind a front top beam 27 of the front frame under the protection of a net supporting shield mechanism 18; in addition, in the process of bolting, the top anchor frame swing mechanism 10 is utilized to drive the top anchor support frame 6 and the top roof bolter 7 to swing by a certain angle in an adaptive manner. Meanwhile, by using the side anchor rod operating device 4 arranged in the tunneling operating space 19, the permanent supporting operation of driving side anchor rods is performed on two sides of the newly exposed roadway space in the side anchor operating space 16 reserved between the supporting front frame 13 and the supporting rear frame 14.
Repeating the tunneling operation, moving the supporting front frame 13 forwards, pulling the supporting rear frame 14, permanently supporting the top of the supporting front frame 13 and the space between the supporting front frame 13 and the supporting rear frame 14, transporting cut coal and rocks out of a tunneling working face, and the like, so that the tunneling operation is carried out under the condition of not completely stopping and retreating, the pushing mechanism 15 pushes and pulls the supporting front frame 13 and the supporting rear frame 14 to move forwards circularly, and the tunneling operation device 1 is matched for continuously tunneling forwards, thereby reducing the time wasted by alternation between different working procedures, providing safety guarantee for the supporting operation of workers, and obviously improving the tunneling efficiency.
