This construction method has the following problems:

[0035] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Please see attached Figure 1 -Attached Figure 6 The present invention discloses an automated flexible anchor drilling support system based on a multi-angle screw conveying technology, wherein the anchor drilling support system comprises an anchor drilling support device 1, wherein the anchor drilling support device 1 comprises an angled axis conveying assembly 2 for controlling the movement of a steel strand 6, an angled axis drilling assembly 3 connected to the angled axis conveying assembly 2, a frame mechanism 4 connected to the angled axis drilling assembly 3, and a frame driving assembly 5 connected to the frame mechanism 4;

[0037] The bevel conveying assembly 2 includes four groups of bevel wheels 21, a bevel wheel cage 22, a bevel wheel synchronous wheel 23, a second servo motor 24, a driving wheel 25, a synchronous belt 26 and a support frame 27. The back of the support frame 27 is connected to the second servo motor 24, the output end of the second servo motor 24 is connected to the axis of the driving wheel 25, the inner side of the synchronous belt 26 is connected to the top outer side of the driving wheel 25, the outer side of the bevel wheel synchronous wheel 23 is rollingly connected to the inner front side of the synchronous belt 26, the middle part of the bevel wheel synchronous wheel 23 is rotatably connected to the hole opened in the top of the support frame 27, the bottom surface of the bevel wheel synchronous wheel 23 is fixedly connected to the top of the four groups of bevel wheels 21, the bottom ends of the four groups of bevel wheels 21 are fixedly connected to the top surface of the bevel wheel cage 22, the inner wall of the bevel wheel synchronous wheel 23 is provided with a hollow opening, and the hollow opening passes through the inner wall of the bevel wheel cage 22, and the bottom surface of the bevel wheel cage 22 is rotatably connected to the inside of the support frame 27.

[0038] In the first embodiment, the four groups of inclined axis wheels 21 are inclined at a rotation angle, and the inclination angle of the four groups of inclined axis wheels 21 is 10°-25°. The inclined axis drilling assembly 3 includes four groups of inclined drilling wheels 31, a conveying wheel 32, a driven wheel 33, a first servo motor 34, a transmission wheel 35 and a driven belt 36. The interior of the support frame 27 is rotatably connected to the top surface of the conveying wheel 32, and the bottom surface of the conveying wheel 32 is fixedly connected to the top of the four groups of inclined drilling wheels 31. The bottom ends of the four groups of inclined drilling wheels 31 are fixedly connected to the top surface of the driven wheel 33, and the middle part of the driven wheel 33 is rotatably connected to the bottom of the support frame 27. The outer side of the bottom of the driven wheel 33 is rollingly connected to the front of the inner wall of the driven belt 36, the back of the inner wall of the driven belt 36 is rollingly connected to the outer side of the transmission wheel 35, the output end of the first servo motor 34 is fixedly connected to the axis of the transmission wheel 35, the side of the first servo motor 34 is fixedly installed at the bottom of the support frame 27, the inclined axis drilling assembly 3 and the inclined axis conveying assembly 2 are symmetrical to each other, the inclination angle of the four groups of inclined drilling wheels 31 is 60°-70°, the hollow mouth passes through the inner wall of the conveying wheel 32 and the driven wheel 33, and the inner wall of the hollow mouth is movably connected to the outer side of the steel strand 6;

[0039] The steel strand 6 is composed of an external tensile structure and a hollow pipe. The hollow steel strand 6 is resistant to axial and radial torsion and has the tensile strength of a traditional steel strand 6. The hollow pipe for conveying liquid is provided inside. The steel strand 6 has good bending performance and can withstand the extrusion and torsion of the oblique axis drilling assembly 3 and the oblique axis conveying assembly 2 without deformation. The outer diameter of the steel strand 6 and the cross section of the inner hollow pipe are kept unchanged. The hollow pipe is a two-way pipe, which is used to convey drilling cooling water during drilling and convey A and B component anchoring agents during anchoring.

[0040] Specifically, the oblique axis conveying assembly 2 is composed of four sets of oblique axis wheels 21, an oblique wheel cage 22, an oblique wheel synchronous wheel 23, a second servo motor 24, a driving wheel 25, a synchronous belt 26 and a support frame 27;

[0041] The bevel axis wheel 21 is made of elastic material and has a guide thread on the surface. The four bevel axis wheels 21 are arranged in a square. A circle is drawn with the outer diameter of the four bevel axis wheels 21. The diameter of the circle is smaller than the diameter of the steel strand 6 passing through the center. The four bevel axis wheels 21 form a rolling friction fit with the steel strand 6.

[0042] Four groups of bevel-axis wheels 21 are installed in the bevel wheel cage 22, and the bevel wheel cage 22 is hard-connected with the bevel wheel synchronous wheel 23. The second servo motor 24 transmits the driving force to the bevel wheel cage 22 through the driving wheel 25 and the synchronous belt 26, so as to realize the forward and reverse rotation control of the bevel wheel cage 22. Because the steel strand 6 forms a rolling friction fit with the bevel-axis wheel 21, the forward and reverse rotation of the bevel wheel cage 22 drives the bevel-axis wheel 21 to roll frictionally on the surface of the steel strand 6. Due to the deviation between the rotation angle of the bevel-axis wheel 21 and the rotation angle of the steel strand 6, a driving force for the radial movement of the steel strand 6 is formed, thereby realizing the forward and reverse direction conveying control of the steel strand 6.

[0043] In the second embodiment, the frame mechanism 4 includes a limiting plate 41, a third servo motor 42 and a transmission roller 43. Both ends of the transmission roller 43 are rotatably connected to the inner walls of the two limiting plates 41. The middle of the transmission roller 43 is fixedly connected to the inner wall of the support frame 27. The side of the left limiting plate 41 is fixedly connected to the third servo motor 42. The output end of the third servo motor 42 is spline-connected to the left end of the transmission roller 43.

[0044] Specifically, through the mutual cooperation between the inclined axis conveying assembly 2 and the inclined axis drilling assembly 3, the concentricity of the center holes of the inclined axis drilling assembly 3 and the inclined axis conveying assembly 2 is ensured, and the third servo motor 42 drives the support frame 27 to rotate axially through the rotating transmission roller 43, so that the steel strands 6 transported by the inclined axis drilling assembly 3 and the inclined axis conveying assembly 2 are pointed in the elevation direction.

[0045] Embodiment 3: The front and rear ends of the two limiting plates 41 are fixedly connected with sleeves 44, the inner walls of the two front sleeves 44 are slidably connected with guide rods 45, the front end of the steel strand 6 is sleeved with a mounting cylinder 61, the front end of the mounting cylinder 61 is fixedly connected with a drill bit 62, and the length of the mounting cylinder 61 is 0.5m-0.7m, the frame drive assembly 5 includes a rack 51, a bidirectional motor 52, a clamping plate 53, a gear 54 and a fixing frame 55, the outer sides of the two racks 51 are slidably connected to the inner walls of the two rear sleeves 44, and the two rear sleeves The sides of the two gears 44 that are close to each other are fixedly connected to the two sides of the fixing frame 55. The outer side of the two-way motor 52 can be detachably mounted on the inner wall of the fixing frame 55. Sliding grooves are provided on both sides of the top of the two sleeves 44 at the rear end. The output end of the two-way motor 52 is fixedly connected to the axis of the gear 54. The gear 54 is located on the inner wall of the sliding groove. The outer side of the gear 54 is meshed with the outer side of the rack 51. The clamping plate 53 is slidably connected to the inner wall of the sliding groove, and the output end of the two-way motor 52 passes through the inner wall of the clamping plate 53. A steel strand 6 is provided inside the support frame 27.

[0046] The displacement sensor is a conventional Hall sensor, which is used to output the position data of the rotation and drilling of the steel strand 6 and for closed-loop control of the drilling operation;

[0047] The 0.5m-0.7m installation barrel 61 plays a role in guiding the drilling path of the steel strand 6. Since the steel strand 6 exhibits elastic deformation characteristics at an axial angle, if only a short drill bit 62 is installed during the drilling process, the drilling of the steel strand 6 will present an uncontrollable path change with a small radius. After adding the 0.5-0.7m installation barrel 61, the front end of the steel strand 6 will have a fixed drilling direction of 0.5-0.7m, thereby expanding the radius of change of the drilling path of the steel strand 6, so as to achieve the purpose of making the drilling path tend to be straight.

[0048] Specifically, the gear 54 is driven by the bidirectional motor 52 to move on the rack 51, and the bidirectional motor 52 then drives the fixed frame 55, the sleeve 44, the limiting plate 41, the inclined axis drilling assembly 3 and the inclined axis conveying assembly 2 to move, and then the steel strand 6 is driven by the frame drive assembly 5 to rotate and drives the drill bit 62 to rotate through the installation cylinder 61, and the steel strand 6 is driven forward by the frame drive assembly 5, and pushes the drill bit 62 forward through the installation cylinder 61, together forming a drilling action.

[0049] The weight, load, size, material and shape of the anchor drilling support device 1 are replaceable, wherein the number, inclination angle, material and friction drive mode of the bevel shaft wheels 21 in the bevel shaft conveying assembly 2 and the bevel shaft drilling assembly 3 are replaceable, the drive mode of the bevel shaft conveying assembly 2 and the bevel shaft drilling assembly 3 are replaceable, and the operation mode and structural form of the frame drive assembly 5 and the frame mechanism 4 are replaceable, such as chain type, oil cylinder push, etc.;

[0050] Working principle:

[0051] The steel strand 6 enters the inclined axis conveying assembly 2, and is driven by the inclined axis wheel 21 to further advance to the inclined axis drilling assembly 3. Since the inclination angle of the inclined drilling wheel 31 of the inclined axis drilling assembly 3 is much larger than that of the inclined axis wheel 21 of the inclined axis conveying assembly 2, when the rotation speed and steering of the inclined axis drilling assembly 3 are synchronized with the inclined axis conveying assembly 2, the steel strand 6 is in a rotating and non-advancing state. When the rotation speed of the inclined axis drilling assembly 3 is greater than that of the inclined axis conveying assembly 2, the steel strand 6 is in a rotating and simultaneously advancing operating state. At this time, the steel strand 6 enters the drilling mode. By adjusting the rotation speed difference between the inclined axis drilling assembly 3 and the inclined axis conveying assembly 2, the rotation and drilling of the steel strand 6 and the corresponding drilling speed and rotation speed can be achieved. By adjusting the rotation direction and speed difference between the inclined axis drilling assembly 3 and the inclined axis conveying assembly 2, the forward and backward movements of the steel strand 6 can be achieved, that is, the purpose of drilling and conveying support materials using only the steel strand 6 at one time without the need for drilling with a drill rod is achieved. At this point, the entire workflow ends.
