[0019] A full-section tunneling, drilling and anchoring integrated device for a large-slope deep inclined shaft in this embodiment includes a hoisting system and a tunneling jumbo. The tunneling jumbo travels on the track 3 under the traction of the hoisting system. The track 3 is arranged along the unilateral excavation surface of the inclined shaft, using 38 steel rails with a gauge of 2.5 m, and is fixed to the lower wall of the inclined shaft by equally spaced anchor bolts.

[0020] The tunneling jumbo includes an upper platform 5, a middle platform 6 and lower construction equipment. The upper platform 5 is provided with a telescopic boom hoisting mechanism 501 and an electric control system. The middle platform 6 is provided with a pumping system, a grouting system and a hydraulic system. The lower construction equipment mainly includes a rock drilling boom 7, a mucking arm 8 and a shotcreting manipulator 9. The side of the tunneling jumbo is supported on the rock wall by a support shoe system 10 to ensure the stability of the jumbo operation.

[0021] The hoisting system includes a winch 1, a steel wire 2 and a track 3 in the horizontal tunnel section of the inclined shaft. One end of the steel wire rope 2 is fixedly connected to the winch 1, and the other end is connected to the tunneling jumbo through the steering wheel 4. The hoisting system is designed according to the total weight of the tunneling jumbo and construction equipment. The winch 1 is set in the upper horizontal tunnel section of the inclined shaft, and the steering wheel 4 is set at the intersection of the upper part of the inclined shaft and the horizontal tunnel. The hoisting system pulls the tunneling jumbo to move along the axial direction of the inclined shaft through the steel wire rope 2.

[0022] The rock drilling boom 7 is located on the lower right side of the tunneling jumbo and is composed of a rock drilling propulsion assembly 701 and a rock drilling propulsion boom 702. The rock drilling propulsion boom 702 is fixed to the lower part of the tunneling jumbo. Anchor holes are drilled and anchor bolts are installed through the rock drilling boom 7, and the drilling depth is 3.5 m.

[0023] The mucking arm 8 is located in the middle of the lower part of the tunneling jumbo and is composed of an upper telescopic arm 801, a lower telescopic arm 802, a slewing drive device 803 and a bucket 804. The upper telescopic arm 801 is fixed to the lower part of the tunneling jumbo. The mucking arm 8 controls the upper telescopic arm 801, the lower telescopic arm 802, the slewing drive device 803 and the bucket 804 to perform mucking operations in a hydraulic manner, and the slewing drive device 803 can rotate 360°.

[0024] The shotcreting manipulator 9 is located on the lower left side of the tunneling jumbo and adopts a fully hydraulic controlled folding + telescopic boom type. It realizes slewing, folding and swinging through the independent telescoping of the boom 901 and the arm 902, and the nozzle 903 realizes 360° slewing and about 240° swinging. When the shotcreting manipulator 9 does not perform shotcreting operations, the entire boom can be retracted and folded without affecting other operations.

[0025] The support shoe system 10 is composed of 3 groups of support shoes, which are respectively located on the upper platform 5, the middle platform 6 and the lower part of the jumbo. The support shoes are driven by hydraulic pressure to tighten the rock wall of the inclined shaft to complete the fixation of the tunneling jumbo.
