[0027] The following describes a one-time use process of the present invention in conjunction with the accompanying drawings: When lateral translation adjustment is required, it is only necessary to start the lateral translation adjustment cylinder 11. Through the extension and retraction action of the piston rod of the lateral translation adjustment cylinder 11, the lateral translation adjustment slide plate 12 and the lateral translation adjustment slider 13 can be driven to slide linearly along the lateral translation adjustment guide slide rod 14, thereby making all components on the lateral translation adjustment slide plate 12 move synchronously, and finally realizing lateral translation adjustment.
[0028] When horizontal rotation and attitude adjustment is required, it is only necessary to start the horizontal rotation and attitude adjustment hydraulic motor 15. The power output shaft of the horizontal rotation and attitude adjustment hydraulic motor 15 will drive the power input worm of the worm gear turntable mechanism 16 to rotate, and then drive the power output worm gear turntable of the worm gear turntable mechanism 16 to rotate, and then make all the components on the power output worm gear turntable of the worm gear turntable mechanism 16 move synchronously, and finally realize horizontal rotation and attitude adjustment.
[0029] When pitch adjustment is required, the pitch adjustment cylinder 18 is simply activated. The piston rod of the pitch adjustment cylinder 18 is retracted and retracted, driving the base support frame 20 to perform a pitch and swing motion about the centerline of the pitch support axis 23. This, in turn, causes all components on the base support frame 20 to move synchronously, ultimately achieving pitch adjustment. At this point, after lateral translation adjustment, horizontal rotation adjustment, and pitch adjustment, the drilling position is completely determined.
[0030] Before drilling, if the anchor rod 56 is a general anchor rod and there is no need for grouting, the grouting valve block 51 is not activated, the piston rod of the valve block push cylinder 54 is extended, and the grouting valve block 51 and the valve block push sliding sleeve 52 are driven to move backward along the valve block push sliding rod 53 through the valve block push force transmission frame 55, so that the friction sealing sleeve at the slurry outlet of the grouting valve block 51 is out of contact with the rear end pipe mouth of the anchor rod adapter spiral tube 50. If the anchor rod 56 is a grouting anchor rod and there is a need for grouting, the grouting valve block 51 is activated, the piston rod of the valve block push cylinder 54 retracts, and the grouting valve block 51 and the valve block push sliding sleeve 52 are driven to move forward along the valve block push sliding rod 53 through the valve block push force transmission frame 55, so that the friction sealing sleeve at the slurry outlet of the grouting valve block 51 is in sealing contact with the rear end pipe mouth of the anchor rod adapter spiral tube 50. The two grouting ports 57 on the grouting valve block 51 can be connected to different grouting materials respectively, or one grouting port 57 can be connected to grouting material and the other grouting port 57 can be connected to clean water, etc. The two grouting ports 57 can work alternately to meet different grouting needs.
[0031] When drilling is required, the anchor rod rotary drive hydraulic motor 48 is first started, and the rotational driving force is input into the reduction gearbox 49. The reduction gearbox 49 then transmits the rotational driving force to the anchor rod 56 through the anchor rod adapter solenoid 50, causing the anchor rod 56 to rotate at the set speed. If grouting is required, grouting material or clean water can be injected into the grouting valve block 51 through the grouting port 57, and then flow into the central grouting channel of the anchor rod 56 through the grouting valve block 51 outlet, the friction seal sleeve, and the anchor rod adapter solenoid 50.
[0032] When the anchor rod 56 obtains the set rotation speed, the anchor rod double-speed advancing cylinder 30 is started, so that the piston rod of the anchor rod double-speed advancing cylinder 30 is extended, driving the cylinder barrel of the anchor rod double-speed advancing cylinder 30 and the anchor rod double-speed advancing guide slide 32 to move forward along the anchor rod double-speed advancing guide slide 31 until the anchor rod double-speed advancing guide slide 32 moves to the front end of the anchor rod double-speed advancing guide slide 31 and close to the front support plate 27. At this time, the distance moved by the cylinder barrel of the anchor rod double-speed advancing cylinder 30 and the anchor rod double-speed advancing guide slide 32 is half of the anchor rod double-speed advancing guide slide 31.
[0033] On this basis, due to the meshing transmission of the first gear and the second gear with the rack, the linear motion of the cylinder barrel of the anchor rod speed-propelling cylinder 30 will be synchronously transmitted to the first sprocket 36, the second sprocket 37, the first gear and the second gear. The first gear and the second gear can be automatically converted into the forward rolling motion of the gear itself under the meshing transmission with the rack. Since the first gear is coaxially arranged with the first sprocket 36 and the second gear is coaxially arranged with the second sprocket 37, the first sprocket 36 and the second sprocket 37 can be synchronously driven to rotate, thereby further driving the chain 35 to move. At this time, the chain 35 will drive the anchor rod speed-propelling slide plate 34 to move synchronously through the chain plate adapter frame 38, thereby moving the anchor rod speed-propelling slide plate 34 from the top end of the cylinder barrel of the anchor rod speed-propelling cylinder 30 to the tail end of the cylinder barrel.
[0034] When the movement of the anchor rod double-speed advancing cylinder 30 and the movement of the anchor rod double-speed advancing slide 34 are superimposed, in the process of the anchor rod double-speed advancing slide 34 moving from the rear end to the front end of the anchor rod double-speed advancing guide slide 31, the movement speed of the anchor rod double-speed advancing slide 34 reaches twice the movement speed of the anchor rod double-speed advancing cylinder 30. Since the anchor rod 56 moves synchronously with the anchor rod double-speed advancing slide 34, the movement speed of the anchor rod 56 is also twice the movement speed of the anchor rod double-speed advancing cylinder 30, thereby realizing the double-speed advancement of the anchor rod 56, so that the anchor rod 56 can quickly extend out of the anchor rod linear feed front support plate 27 and contact the rock wall.
[0035] When the anchor rod 56 has completed the double-speed advancement, the scissor-type anchor rod clamp 42 is activated. The telescopic action of the piston rod of the clamp driving cylinder 45 can be transmitted to the scissor-type anchor rod clamp 42 in sequence through the transmission block 44 and the transmission double link 43, so that the scissor-type anchor rod clamp 42 can be opened and closed. The scissor-type anchor rod clamp 42 clamps the anchor rod 56 to prevent the anchor rod 56 from drifting, bending or shaking during the drilling process, ensuring the accuracy of the drilling direction. At the same time, the telescopic action of the piston rod of the anchor rod clamping and stabilizing assembly push-pull cylinder 47 can adjust the position of the anchor rod clamping and stabilizing assembly 7, including the scissor-type anchor rod clamp 42, to achieve precise adjustment of the clamping position of the scissor-type anchor rod clamp 42 on the anchor rod 56.
[0036] When the anchor rod 56 completes stable clamping, the anchor rod linear feed cylinder 26 is started, driving the anchor rod linear feed front support plate 27, the anchor rod linear feed rear support plate 28, the anchor rod linear feed guide slide 29 and the anchor rod double-speed advancement guide slide 31 to move forward as a whole, driving all components on the anchor rod double-speed advancement guide slide 31 and the anchor rod 56 to move forward as a whole, and finally realizing the linear feeding of the anchor rod 56, so that the rotating anchor rod 56 is drilled into the rock wall until the anchor rod 56 reaches the set drilling depth.
[0037] When the anchor rod 56 reaches the set drilling depth, the anchor rod rotation drive hydraulic motor 48 is started in reverse, and the anchor rod adapter screw 50 is driven to rotate in the opposite direction through the reduction gear box 49, so that the anchor rod adapter screw 50 is disconnected from the anchor rod 56 in the borehole, and then the anchor rod linear feed assembly 5 and the anchor rod double-speed propulsion assembly 6 are adjusted back to the initial position.
[0038] When the anchor rod linear feed assembly 5 and the anchor rod double-speed propulsion assembly 6 return to their initial positions, the anchor rod replacement execution cylinder 71 is first started, and the anchor rod replacement transmission rocker arm 72 is driven to move by the extension and contraction of the piston rod of the anchor rod replacement execution cylinder 71, and then the anchor rod replacement swing shaft 70 is driven to swing by the anchor rod replacement transmission rocker arm 72 until the free end of the anchor rod replacement limit frame 74 is driven to rotate to the gap between the front C-shaped ring stop sleeve 65 and the rear C-shaped ring stop sleeve 67, and the swing angle of the anchor rod replacement swing shaft 70 is precisely controlled by the data feedback of the second angle measurement encoder 77.
[0039] When the free end of the anchor rod replacement limit frame 74 is adjusted into place, the automatic rod replacement hydraulic motor 62 is started, and the anchor rod replacement drive shaft 64 is driven to rotate through the worm gear reducer 63, and then the front anchor rod clamping plate 66 and the rear anchor rod clamping plate 68 are driven to rotate synchronously until an anchor rod 56 moves to the gap between the front C-shaped ring stop sleeve 65 and the rear C-shaped ring stop sleeve 67 and comes into contact with the free end of the anchor rod replacement limit frame 74. The rotation angle of the anchor rod replacement drive shaft 64 is precisely controlled by the data feedback of the first rotation angle measurement encoder 76.
[0040] When the anchor rod 56 comes into contact with the free end of the anchor rod replacement limit frame 74, the anchor rod replacement manipulator 73 is started to move the anchor rod replacement limit pressure plate 75 until the anchor rod 56 is firmly clamped between the anchor rod replacement limit pressure plate 75 and the free end of the anchor rod replacement limit frame 74, and then the anchor rod replacement execution cylinder 71 is started again to make the anchor rod replacement swing shaft 70 swing in the opposite direction until the anchor rod 56 is transferred from the front anchor rod clamping plate 66 and the rear anchor rod clamping plate 68 to the coaxial position in front of the anchor rod adapter screw 50, so that the rear end of the anchor rod 56 is pressed against the front end pipe mouth of the anchor rod adapter screw 50, and then the anchor rod rotation drive hydraulic motor 48 is started to drive the anchor rod adapter screw 50 to rotate until the anchor rod adapter screw 50 is screwed and fixed to the anchor rod 56, and the automatic replacement of the anchor rod 56 is completed.
[0041] After the automatic replacement of the anchor rod 56 on the anchor rod adapter screw 50 is completed, the automatic rod changing assembly 9 is first adjusted back to the initial position, and then the anchor rod speed advancing assembly 6 is reactivated until the front end of the anchor rod 56 on the anchor rod adapter screw 50 is pressed against the rear end of the anchor rod 56 in the borehole, and then the anchor rod rotation drive hydraulic motor 48 is started again to drive the anchor rod adapter screw 50 to rotate until the front end of the anchor rod 56 on the anchor rod adapter screw 50 is screwed and fixed to the rear end of the anchor rod 56 in the borehole.
[0042] After the front and rear anchor rods 56 are screwed together, the anchor rod linear feed assembly 5, anchor rod clamping and securing assembly 7, and anchor rod rotary drive and grouting assembly 8 are reactivated, and the drilling operation is continued using the extended anchor rod 56 until the set drilling depth is reached again. Repeating this process achieves fully automated connection between drilling and automatic rod changing.
