[0043] like Figure 1-9 As shown, the mobile vehicle 1 is installed on the track using the track traveling wheels 101, and the track traveling wheels 101 are driven by the motor to rotate to move and perform the work of automatic traveling and drilling;

[0044] The anti-tilt brake device 2 provides a braking function. The lifting electric cylinder 201 is started to descend, and then the electric cylinder is used to retract the side clamps 203 on both sides. The side clamps 203 on both sides are buckled outside the track. When braking is needed, the two sets of side clamps 203 are retracted to contact the track to perform the brake. Further lowering the blocking block 202 can accelerate the deceleration effect and achieve rapid braking.

[0045] The track travel wheel 101 is made of rubber wheels, and the mobile vehicle 1 is made of aluminum alloy. The overall modular and lightweight design is easy to carry. A sensor is also installed at the assembly of the track travel wheel 101 to detect the translation distance of the trolley. The anti-tilt brake device 2 is locked to achieve braking. It has good braking performance during operation and also has anti-tilt and anti-slip protection functions;

[0046] The first-stage arm cylinder 102, the second-stage arm cylinder 103, the first-stage mechanical arm 3 and the second-stage mechanical arm 4 constitute a four-bar linkage. By adjusting the extension and contraction range of the first-stage arm cylinder 102 and the second-stage arm cylinder 103, the deformation of the four-bar linkage can be controlled to make the second-stage mechanical arm 4 swing, and the transmission mechanism 5 can be moved close to the position where the hole needs to be drilled as needed.

[0047] The transmission mechanism 5 can further adjust the angle, start the swing motor 501 to drive the angle adjustment gear 502 to rotate, and use the angle adjustment gear 502 to apply force to the reverse thrust toothed disc 401 to adjust the angle of the transmission mechanism 5 itself. Further, start the drive motor 503 to drive the rotating slide 6 to rotate, and the angle of the rotating slide 6 can be adjusted so that the drill bit of the drilling machine 7 can be aligned with the drilling position; the operating table can be connected to realize vehicle translation, drilling rig start and stop and drilling rig propulsion, and extension arm height and deviation adjustment; the double-arm folding design is adopted, which is easy to carry and assemble. The drilling height can be controlled by controlling the extension angle of the folding arm, and the drilling machine 7 can be driven to move by controlling the propulsion electric cylinder 601 to achieve drilling depth control;

[0048] In addition, it is necessary to add a simple hook for overall lifting, reserve a place for installing a fire extinguisher, and reserve a place for upgrading and installing spare parts such as expansion bolts and leaky cable clamps;

[0049] The drilling machine 7 is used to drill holes in the wall by the aforementioned control method, and the annular airbag 906 first contacts and fits on the wall, conforming to the gap between the wall and the assembly frame 902, and then the exhaust fan 803 is started to extract air, and the air passes through the air inlet port 905 into the conical glass cover 901, passes through the bellows 9 into the collection device 8, and then passes through the exhaust channel 801 to be discharged. During this period, the dust generated by the drilling is driven outward by the air flow, and the air is discharged through the filter cotton net 802, and the intercepted dust falls into the receiving bottle 804 for collection, and the receiving bottle 804 can be disassembled for cleaning later;

[0050] Each component uses quick-release parts, the cable connection adopts an integrated plug design, and each part is designed with handles for easy carrying, which can be quickly disassembled and installed on site. The whole system is powered by a portable power supply (battery). The battery is detachable for easy transportation and replacement, and a reserved position and interface are provided for generator power supply.

[0051] Embodiment 2: Based on Embodiment 1, the primary arm cylinder 102 and the secondary arm cylinder 103 may be replaced by other driving modes, such as setting a reducer and a motor between the primary robot arm 3 and the secondary robot arm 4 for driving, and adjusting by simulating the joints to adjust each part individually.

[0052] Embodiment 3: Based on Embodiment 1, the interior of the conical glass cover 901 can be illuminated by using an illumination lamp 904, and the drilling process can be observed through the conical glass cover 901, so as to facilitate monitoring of the drilling situation;

[0053] As the drill bit goes deeper, the bellows 9 will be folded. The spring rod 903 provides a guiding effect to ensure that the bellows 9 is folded correctly and avoids bending to one side, so that the bellows 9 can work normally.

[0054] Specific usage and function of this embodiment: In the present invention, a track needs to be preset in the tunnel, and the mobile vehicle 1 is installed on the track using the track travel wheel 101, and the track travel wheel 101 is driven by a motor to rotate to move, and the work of automatic travel drilling is performed;

[0055] The anti-tilt brake device 2 provides a braking function. The lifting electric cylinder 201 is started to descend, and then the electric cylinder is used to retract the side clamps 203 on both sides. The side clamps 203 on both sides are buckled outside the track. When braking is needed, the two sets of side clamps 203 are retracted to contact the track to perform the brake. Further lowering the blocking block 202 can accelerate the deceleration effect and achieve rapid braking.

[0056] The first-stage arm cylinder 102, the second-stage arm cylinder 103, the first-stage mechanical arm 3 and the second-stage mechanical arm 4 constitute a four-bar linkage. By adjusting the extension and contraction range of the first-stage arm cylinder 102 and the second-stage arm cylinder 103, the deformation of the four-bar linkage can be controlled to make the second-stage mechanical arm 4 swing, and the transmission mechanism 5 can be moved close to the position where the hole needs to be drilled as needed.

[0057] The transmission mechanism 5 can further adjust the angle, start the swing motor 501 to drive the angle adjustment gear 502 to rotate, and use the angle adjustment gear 502 to apply force to the reverse thrust toothed disc 401 to adjust the angle of the transmission mechanism 5 itself. Further, start the drive motor 503 to drive the rotating slide 6 to rotate, and the angle of the rotating slide 6 can be adjusted so that the drill bit of the drilling machine 7 is aligned with the drilling position;

[0058] The drilling machine 7 is used to drill holes in the wall by the aforementioned control method, and the annular airbag 906 first contacts and fits on the wall, conforming to the gap between the wall and the assembly frame 902, and then the exhaust fan 803 is started to extract air, and the air passes through the air inlet port 905 into the conical glass cover 901, passes through the bellows 9 into the collection device 8, and then passes through the exhaust channel 801 to be discharged. During this period, the dust generated by the drilling is driven outward by the air flow, and the air is discharged through the filter cotton net 802, and the intercepted dust falls into the receiving bottle 804 for collection, and the receiving bottle 804 can be disassembled for cleaning later;

[0059] While drilling, the lighting lamp 904 can be turned on to illuminate the inside of the conical glass cover 901, and the drilling process can be observed through the conical glass cover 901, which is convenient for monitoring the drilling situation. As the drill bit goes deeper, the bellows 9 will be folded, and the spring rod 903 provides a guiding effect, which can ensure that the bellows 9 is folded correctly, and avoid the bellows 9 bending to one side to affect the drill bit;

[0060] Through program setting, automatic drilling operations at a fixed distance can be performed.
