DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Reference Figures 1 to 12 The present embodiment discloses an anchor drilling machine for slope support, including a traction machine 1, on which an extension arm 2 is installed, the extension arm 2 includes a fixed frame 21 installed on the traction machine 1, on which a telescopic cylinder 22 is fixedly installed, and an output shaft of the telescopic cylinder 22 is fixedly connected to an extension frame 23 slidably connected to the fixed frame 21, on which a support seat 24 and a baffle 25 are fixedly installed, on which a plurality of guide rails 26 are fixedly installed, and on which a hollow casing 27 is fixedly installed for guiding and limiting a drill rod.

[0036] Reference Figure 3The drilling machine also includes a clamping assembly 3, which includes a hollow gear 31 and two sets of racks 32 meshing with the hollow gear 31. The racks 32 are distributed on opposite sides of the hollow gear 31 and move in opposite directions. The hollow gear 31 is fixedly mounted on the hollow sleeve 27. The racks 32 are slidably connected to the baffle 25 through the corresponding guide rails 26. A clamping block 33 is fixedly mounted on the rack 32. The clamping block 33 is arc-shaped and its axis is on the same horizontal plane as the axis of the hollow gear 31. The two sets of clamps The blocks 33 are distributed on both sides of the hollow casing 27 and are used to clamp and fix the drill rod. An anti-sliding block 34 is fixedly installed on the inner side of the clamping block 33 to further improve the stability of the drill rod clamping. A top plate 35 is fixedly installed on one end of the lower rack 32, and an elastic member 36 is fixedly installed on the top plate 35. One end of the elastic member 36 is fixedly connected to the top plate 35, and the other end is fixedly connected to the baffle 25. The elastic member 36 is used to pull the rack 32 to move, thereby driving the clamping block 33 away from the hollow casing 27.

[0037] Reference Figure 1 , Figure 4 and Figure 5 A protective frame 4 is fixedly mounted on the fixed frame 21, and a support rod 41 is fixedly mounted on the protective frame 4. The support rod 41 is tilted upward and is used to place the drill rod. A driving assembly 5 is installed on the support seat 24. The driving assembly 5 includes a first reduction motor 51 fixedly mounted on the support seat 24. The output shaft of the first reduction motor 51 is fixedly connected to a flange 52. An internal hollow connector 53 is fixedly mounted on the flange 52. The connector 53 is coaxial with the hollow casing 27. The drill rod is threadedly connected to the connector 53, so that the drill rod is fixed to the connector 53. The driving assembly 5 also includes an intake ring 54 fixedly mounted on the support seat 24. The intake ring 54 is rotatably connected to the connector 53 and communicates with the inside of the connector 53 through a plurality of intake holes 55 provided on the connector 53. An air nozzle 56 is installed on the intake ring 54 for connecting to the supercharging device. The first reduction motor 51 rotates, thereby driving the flange 52, the connecting head 53 and the drill rod to rotate, and the telescopic cylinder 22 pushes the extension frame 23, the support seat 24 and the first reduction motor 51 to move, thereby realizing continuous drilling operation. During the drilling operation, the booster device continuously provides high-pressure gas to the intake ring 54 through the air nozzle 56. The gas enters the connecting head 53 and the inside of the borehole through the air inlet hole 55 and is ejected from the drill bit, thereby accelerating the blowing of rock chips and dust in the borehole out of the borehole, thereby improving the drilling efficiency. The gas can also effectively reduce the temperature of the drill bit to avoid overheating damage or performance degradation of the drill bit.

[0038] Reference Figures 6 to 11A second reduction motor 6 and a rotating assembly 7 are installed on the protective frame 4. The rotating assembly 7 includes a transmission rod 71 rotatably connected to the protective frame 4. The output shaft of the second reduction motor 6 is fixedly connected to the transmission rod 71 for driving it to rotate. Two groups of support blocks 72 are fixedly installed on the transmission rod 71. A first hydraulic cylinder 73 is fixedly installed on the support block 72. The output shaft of the first hydraulic cylinder 73 is fixedly connected to a lifting block 74 slidably connected to the support block 72. A second hydraulic cylinder 75 is fixedly installed on the lifting block 74. The output shaft of the second hydraulic cylinder 75 is fixedly connected to a push-out frame 76 slidably connected to the lifting block 74. The push-out frame 76 is provided with an inclined surface 761 and a supporting surface 762. The supporting surface 762 is parallel to the moving direction of the push-out frame 76, and there is a set angle between the inclined surface 761 and the supporting surface 762.

[0039] A pressure sensor 77 is fixedly installed on the push-pull frame 76, and a push block 78 is installed on the pressure sensor 77. An arc groove 781 is provided on the push-pull frame 78 for assisting in positioning when clamping the drill rod. Two groups of support shafts 79 are rotatably connected to the lifting block 74. One end of the support shaft 79 is fixedly connected to a clamping rod 710, and the other end is fixedly connected to a lever 711. The lever 711 and the clamping rod 710 are located on both sides of the lifting block 74 and are arranged parallel to each other. The end of the lever 711 away from the support shaft 79 is fixedly connected to a fixed column 712, and the fixed column 712 is at the same height of the lever 711. The two fixed columns 712 are connected by a tension spring 713. The tension spring 713 pulls the ends of the two groups of levers 711 away from the support shaft 79 to abut against the push-pull frame 76, so that the two groups of clamping rods 710 are in an expanded state. A positioning groove 714 is provided on the clamping rod 710 for positioning and centering when clamping the drill rod. After the drill rod to be replaced is placed on the ejector block 78, the ejector frame 76 pushes the push rod 711, so that the end of the clamping rod 710 abuts against the top of the drill rod, and the top limit of the drill rod is achieved. As the ejector frame 76 continues to rise, the push rod 711 contacts the support surface 762, and the clamping rod 710 always remains in a closed state until the ejector block 78 pushes the drill rod into the positioning groove 714 and fixes it. When the pressure sensor 77 detects that the pressure reaches the set threshold, the clamping action of the drill rod is completed.

[0040] Reference Fig.12 A fixed shaft 8 is fixedly installed on the support block 72 close to the rack 32, and an arc block 9 is fixedly installed on the fixed shaft 8 for pushing the top plate 35. Under the action of the elastic member 36, the top plate 35 is always in contact with the arc block 9. The arc block 9 includes a first arc surface 91 and a second arc surface 92. The axial distance between the first arc surface 91 and the fixed shaft 8 gradually increases, and the axial distance between the second arc surface 92 and the fixed shaft 8 is equal, so that when the top plate 35 contacts the first arc surface 91, the top plate 35 continues to move, and when the top plate 35 moves to the second arc surface 92, the position remains unchanged. This process is a pressure-maintaining state to avoid excessive clamping of the drill rod and damage to the drill rod.

[0041] Working principle: the drill rod passes through the hollow casing 27 and is screwed and fixed with the connecting head 53. The output shaft of the first reduction motor 51 drives the flange 52, the connecting head 53, the drill rod and the drill bit to rotate. The telescopic cylinder 22 pushes the extension frame 23, the support seat 24 and the first reduction motor 51 to move, thereby realizing continuous drilling operation. During the drilling operation, the booster device continuously provides high-pressure gas to the intake ring 54 through the air nozzle 56. The gas enters the connecting head 53 and the inside of the borehole through the air inlet hole 55 and is ejected from the drill bit, thereby accelerating the blowing out of the rock cuttings and dust in the borehole.

[0042] When adding drill pipe, follow Figure 6 From the middle perspective, the second reduction motor 6 drives the rotating assembly 7 to rotate counterclockwise and cooperates with the first hydraulic cylinder 73 to push the lifting block 74 to move, so that the unfolded clamping rod 710 is adapted to the position of the support rod 41, and the drill rod on the support rod 41 is pushed between the clamping rods 710, and the first hydraulic cylinder 73 drives the lifting block 74 to reset.

[0043] The second hydraulic cylinder 75 drives the pushing frame 76 to push the push rod 711, and the push rod 711 moves from the inclined surface 761 to the supporting surface 762, so that the end of the clamping rod 710 abuts against the top of the drill rod. As the pushing frame 76 continues to rise, the push rod 711 continues to contact the supporting surface 762, and the clamping rod 710 always remains in a closed state until the push block 78 pushes the drill rod into the positioning groove 714 and fixes it. When the pressure sensor 77 detects that the pressure reaches the set first threshold, the clamping action of the drill rod is completed.

[0044] The second reduction motor 6 drives the rotating assembly 7, the fixed shaft 8 and the arc block 9 to rotate clockwise, and the arc block 9 pushes the top plate 35 and the rack 32 to move, and drives another set of racks 32 to move through meshing transmission. The two sets of racks 32 drive the clamping block 33 to close to the drill rod and clamp the fixed drill rod, and the output shaft of the first reduction motor 51 rotates in the opposite direction. At the same time, the telescopic cylinder 22 drives the first reduction motor 51 to move away from the baffle 25, so that the connecting head 53 is separated from the drill rod that has been drilled into the slope, and the first hydraulic cylinder 73 pushes the lifting block 74 to move to the set position, so that the drill rod on the clamping rod 710 is coaxial with the connecting head 53, and the telescopic cylinder 22 drives the first reduction motor 51 and the connecting head 53 to move toward the clamping rod 710, and the first reduction motor 51 drives the connecting head 53 to rotate forward, thereby locking the connecting head 53 and the drill rod.

[0045] After one end of the drill rod is locked with the connecting head 53, the second hydraulic cylinder 75 drives the push-pull frame 76 to return, so that the pressure value of the pressure sensor 77 drops to a second threshold value, and the second threshold value is less than the first threshold value. At this time, the ejector block 78 is still in contact with the drill rod but is completely fixed and tightened. When the telescopic cylinder 22 drives the first reduction motor 51 and the connecting head 53 to continue to move in the drilling direction, the drill rod on the clamping rod 710 moves relative to the clamping rod 710, and the first reduction motor 51 drives the connecting head 53 and the drill rod on the clamping rod 710 to rotate, so that it is screwed and fixed with the drill rod drilled into the slope protection, thereby realizing the installation of the newly added drill rod.

[0046] When unloading the drill pipe, follow the same Figure 6 From the perspective of perspective, first, the telescopic cylinder 22 drives a section of the drill rod to the position when the drill rod is installed, and the second reduction motor 6 drives the rotating assembly 7, the fixed shaft 8 and the arc block 9 to rotate clockwise, so that the clamping block 33 clamps the drill rod at the mouth of the hollow casing 27, and the clamped drill rod is the next section of the drill rod to be disassembled. The clamping rod 710 moves and locks on the drill rod with disassembly, and the pressure value of the pressure sensor 77 is in the second threshold state. The first reduction motor 51 drives the connecting head 53 and the drill rod to be disassembled to rotate. At the same time, the telescopic cylinder 22 drives the first reduction motor 51 to move away from the borehole, so that the drill rod to be disassembled is separated from the next section of the drill rod. After separation, the output shaft of the second hydraulic cylinder 75 is extended, so that the push-pull frame 76 drives the ejection block 78 to clamp the drill rod until the pressure value of the pressure sensor 77 reaches the first threshold, and the drill rod is fixed. In the same way as the above-mentioned drill rod disassembly method, the connection between the drill rod and the connecting head 53 is separated, thereby realizing the disassembly of the drill. The next section of drill pipe is connected again through the connector 53, and then the new section of drill pipe is driven to move to the disassembly position, and the disassembly is continued, thereby realizing a continuous disassembly process.
