For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0028] like Figure 1-2As shown, an anchor cable intelligent drilling vehicle for self-forming lanes without coal pillars includes a crawler drive device 1, a mounting seat 6, a turning frame 2 and a drilling device. The crawler drive device 1 adopts a conventional commercially available small and medium-sized crawler drive vehicle, which can be driven by electricity or an internal combustion engine. A mounting station is provided above the crawler drive device 1, and a first hinge point and a second hinge point with a height difference in the longitudinal direction are provided on the mounting station. Specifically, the mounting station is a fixed seat fixed to the middle part of the upper part of the crawler drive device 1, and a first hinge point and a second hinge point are provided on a side of the fixed seat corresponding to the rear of the vehicle. The mounting seat 6 is hinged to the mounting station through the turning frame 2, and the turning frame 2 can be driven by the first driving rod 3 and the second driving rod 4 located on both sides thereof, so that the mounting seat 6 drives the drilling device to adjust the angle, so that the turning frame 2 can adapt the drilling angle according to actual needs.

[0029] In this embodiment, the flip frame 2 is hinged between the first hinge point and one end of the mounting base 6. The mounting base 6 can be square or round. The other end of the mounting base 6 is hinged to the middle of the flip frame 2 through the first driving rod 3, and the middle of the flip frame 2 is hinged to the second hinge point through the second driving rod 4. Among them, hinge plates corresponding to the flip frame 2 and the first driving rod 3 are provided on both sides of the mounting base 6. The drilling device includes a base 11 and a drilling rig 10. The drilling rig 10 is provided with a detachable drill bit. In other embodiments, an independent drill bit disassembly robot arm can be matched to achieve fully automated operation. There are no excessive restrictions on the robot arm used for drill bit replacement.

[0030] Preferably, the mounting seat 6 is square, and the base 11 is slidably assembled on the mounting seat 6 through a slide rail 12. A third driving rod 7 corresponding to the hinged base 11 is provided on both sides of the mounting seat 6; thereby, the first-level push of the drill rig 10 can be achieved by driving the third driving rod 7, thereby meeting the demand for drilling holes on the higher tunnel top surface. The drill rig 10 is slidably assembled along the extension direction of the slide rail 12, and a driving mechanism corresponding to the drill rig 10 is provided on the base 11. Under the drive of the driving mechanism, the second-level push of the drill rig 10 is achieved, thereby meeting the drilling needs of the drill rig 10.

[0031] In an optional embodiment, a guide column 8 parallel to the slide rail 12 is provided above the base 11, and fixed plates are provided at both ends of the base 11 in the longitudinal direction. The two ends of the guide column 8 are fixed on the fixed plates. The drilling rig 10 is slidably assembled along the guide column 8 through a slider 13. A through-hole corresponding to the guide column 8 is provided in the middle of the slider 13. The driving mechanism includes a driving motor and a conveyor chain 9. The conveyor chain 9 is a conventional chain. Sprockets 14 are provided on both sides of the two ends of the base 11. The guide column 8 is located between the two sprockets 14. The two sprockets 14 located at the same end of the base 11 are connected to each other through the same transmission shaft, one of which is connected to the driving motor. Therefore, there is a height difference between the guide column 8 and the transmission shaft, which can avoid mutual interference between the two. The two conveyor chains 9 are respectively assembled on the sprockets 14 on both sides of the base 11, thereby forming two sets of chain conveying mechanisms on both sides of the base 11. The two conveyor chains are correspondingly connected to both sides of the slider 13, so as to drive the conveyor chain 9 through the two conveyor chains to drive the slider 13 to slide along the guide column 8, thereby ensuring the stability of pushing the drilling rig 10.

[0032] In an optional embodiment, the flip frame 2 is an H-shaped structure, and the two second drive rods 4 are respectively located on both sides of the H-shaped structure. This structure of the flip frame 2 makes the flip frame 2 have higher strength and stability, can bear the weight of the mounting base 6 and the drilling device, and ensure stability during the flipping process, while avoiding motion interference between the second drive rod 4 and the first drive rod 3 during the rotation process.

[0033] In an optional embodiment, the drilling rig 10 is equipped with a torque detection sensor. The first, second, and third drive rods 3, 4, and 7 are hydraulic rods. The crawler drive unit 1 is equipped with a hydraulic station and a controller 15. The hydraulic station includes a hydraulic pump, a hydraulic oil tank, and a solenoid valve. The hydraulic pump is connected to the first, second, and third drive rods 3, 4, and 7 through the solenoid valves. The solenoid valves, the drilling rig 10, the torque detection sensor, and the drive motor are connected to the controller accordingly. The torque detection sensor monitors torque changes during the drilling process in real time. When the torque exceeds a set value, the controller can promptly adjust the operating parameters of the drilling rig 10 or stop the drilling rig 10 to prevent damage to the drill bit or poor drilling quality. The base 11 is provided with side panels corresponding to the sprockets 14 on both sides. The drive motor is bolted to the side panels. The drive motor is a stepper motor, which can control the drilling process.

[0034] In addition, the drilling vehicle is automatically controlled by presetting a program in the controller to achieve intelligent drilling. There is no restriction on the preset control program, and those skilled in the art can set it according to actual work needs.

[0035] The slide rail 12 is a dovetail-shaped guide bar, and the mounting seat 6 is provided with a dovetail groove that is compatible with the dovetail-shaped guide bar. The dovetail-shaped guide bar is located on the lower surface of the base 11. The two can be fixed by welding or formed as one piece. The width of the mounting seat 6 is greater than the base 11. Two third driving rods 7 are correspondingly assembled on the parts of the mounting seat 6 on both sides of the base 11, and blocks corresponding to the dovetail grooves are set at both ends of the base 11 to prevent the slide rail 12 from falling out.

[0036] In an optional embodiment, when actually operating inclined drilling, the equipment completely requires the support force provided by the turning frame 2. Since the inclined force angle will cause the crawler drive device 1 to be unstable, the end of the base 11 away from the drill bit of the drilling rig 10 is connected to a support plate through the fourth drive rod 5. After the drilling rig 10 is in place, the fourth drive rod 5 is extended and contacts the ground or the side wall of the tunnel, thereby providing reverse support force for the drilling rig 10 to ensure the stability of drilling. The end of the support plate away from the base 11 is provided with evenly distributed conical protrusions, which can improve the anti-slip performance of the support plate. The support plate is hinged to the piston end of the fourth drive rod 5, which can increase the support area with the tunnel ground or side wall in the inclined state to ensure the stability of the support.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
