[0041] The specific implementation process of the present invention is described below through multiple embodiments. Example 1

[0042] See also Figures 1 to 8 This embodiment discloses a specific implementation of a multifunctional single-arm anchor drilling vehicle.

[0043] See also Figures 1 to 8 A multifunctional single-arm anchor drilling vehicle includes a vehicle body 1 and a drilling and anchoring part 2; an I-beam clamping groove 3 is provided on the top of the drilling and anchoring part 2; a vertical lifting component 4 is provided on the vehicle body 1, and a rotary component 5 is provided on the vertical lifting component 4; the vertical lifting component 4 drives the rotary component 5 to rise and fall, and the rotary component 5 drives the drilling and anchoring part 2 to rotate.

[0044] Specifically, see Figures 1 to 8 In order to adapt to the narrow working space, the drilling and anchoring part 2 is provided with a drilling arm. The purpose of the drilling and anchoring part 2 is to drive anchor rods to the top and side of the tunnel. The vertical lifting component 4 can drive the lifting of the drilling and anchoring part 2 to adapt to tunnels of different heights; the rotary component 5 can drive the drilling and anchoring part 2 to rotate, so that the drilling and anchoring part 2 can drive anchor rods to the top of the tunnel in an inclined manner, or drive anchor rods to the side of the tunnel in a horizontal manner; by arranging an I-beam clamping groove 3 at the top of the drilling and anchoring part 2, the coordinated operation of anchor rod driving and supporting the I-beam at the top of the tunnel at any time is realized, ensuring that support can be achieved at any time after the anchor rod is driven, thereby improving the safety of the tunnel. At the same time, it avoids the use of manual lifting of I-beams or the use of other equipment to lift I-beams, making full use of the narrow space and improving the working efficiency.

[0045] To further enhance the functionality of the single-arm anchor drilling rig, see Figures 1 to 8The drilling and anchoring part 2 includes a drill arm assembly 21 and an anchor cable clamping assembly 22, and the anchor cable clamping assembly 22 is used to clamp the anchor cable; the drill arm assembly 21 includes a drill arm support frame 211 and a drill arm body 212; the anchor cable clamping assembly 22 includes a first top plate 221, a second top plate 222, and a first pinching wheel 223 and a second pinching wheel 224 arranged between the first top plate 221 and the second top plate 222. A first circular hole 2211 is provided in the first top plate 221, and a second circular hole 2221 is provided in the second top plate 222. The anchor cable passes through the second circular hole 2221, the clamping space of the first pinching wheel 223 and the second pinching wheel 224, and the first circular hole 2211 in sequence. When the first pinching wheel 223 and the second pinching wheel 224 rotate When the anchor cable is clamped and delivered, the first top plate 221 and the second top plate 222 are fixed to the outer wall of the I-beam clamping groove 3; a vertical oil cylinder is arranged on the drill arm support frame 211, and the vertical oil cylinder includes a telescopic rod 2111 and a cylinder barrel 2112, and a first guide rod 2113 and a second guide rod 2114 are respectively arranged on both sides of the cylinder barrel 2112, and a first guide block 2115 and a second guide block 2116 are arranged on the drill arm support frame 211, the first guide rod 2113 slides along the first guide block 2115, and the second guide rod 2114 slides along the second guide block 2116, and the telescopic rod 2111 drives the second top plate 222 to rise and fall through the top of the cylinder barrel 2112 with the bottom of the drill arm support frame 211 as support. By arranging the anchor cable clamping assembly 22 on the outer wall of the I-beam clamping groove 3, the anchor cable is clamped and delivered to the top of the tunnel through the rotation of the first clamping wheel 223 and the second clamping wheel 224, which reduces the labor intensity of manual anchor cable transportation and improves the work efficiency of anchor cable transportation.

[0046] See also Figure 5 In order to make the I-beam clamping groove 3 clamp the I-beam, a clamping cylinder 31 is also provided on the outer wall of the I-beam clamping groove 3, and the telescopic rod of the clamping cylinder 31 passes through the outer wall of the I-beam clamping groove 3. The clamping cylinder 31 drives the clamping block 32 to clamp the I-beam, and the clamping block 32 is provided on the inner wall of the I-beam clamping groove 3; after the I-beam is placed in the I-beam clamping groove 3, the clamping cylinder 31 is started and the clamping block 32 is pushed to clamp the I-beam.

[0047] See also Figure 5The pinching principle of the first pinch wheel 223 and the second pinch wheel 224 is as follows: a hinge point 225 is set between the first top plate 221 and the second top plate 222, and the hinge point 225 is hinged to the first L-shaped swing arm 226 and the second L-shaped swing arm 227. A clamping cylinder 228 is set between the first L-shaped swing arm 226 and the second L-shaped swing arm 227. The first L-shaped swing arm 226 drives the first pinch wheel 223, and the second L-shaped swing arm 227 drives the second pinch wheel 224. The clamping cylinder 228 drives the first pinch wheel 223 and the second pinch wheel 224 to clamp or release the anchor cable through the first L-shaped swing arm 226 and the second L-shaped swing arm 227. The first pinch wheel 223 is hydraulically driven. The motor 229 drives the motor 229; specifically, when it is necessary to clamp the anchor cable, the anchor cable first passes through the second circular hole 2221 and enters the clamping space of the first pinching wheel 223 and the second pinching wheel 224, the clamping cylinder 228 drives the first pinching wheel 223 and the second pinching wheel 224 to clamp the anchor cable, and then the hydraulic motor 229 is started to clamp the anchor cable through the relative rotation of the first pinching wheel 223 and the second pinching wheel 224; when it is not necessary to clamp the anchor cable, the clamping cylinder 228 drives the first pinching wheel 223 and the second pinching wheel 224 to loosen and stop the hydraulic motor 229. At this time, the space between the first pinching wheel 223 and the second pinching wheel 224 is sufficient for the anchor rod to pass through, so that the drill arm body 212 can install the anchor rod and perform the anchor rod driving operation.

[0048] Because the anchor cable has a certain elasticity, when the fast delivery of the anchor cable is about to be completed, the tail of the anchor cable will swing due to the stress and bending of the anchor cable itself. When the anchor cable swings, it will injure the operator nearby and cause a safety accident. To avoid such accidents, see Figure 5 and Figure 6 , an operating table 51 is set above the rotating component 5, and a support rod 52 and a ring 53 are flipped on the operating table 51. The support rod 52 is set on the operating table 51 by a flip mechanism, and the ring 53 is fixed to the end of the support rod 52; when the vertical cylinder is raised, the ring 53 is flipped to the bottom of the second circular hole 2221; the ring 53 plays the role of restraining the tail of the anchor cable, which can reduce the range of the anchor cable swinging; in order to further reduce the range of the anchor cable swinging, an internal thread is set on the ring 53, and a cylindrical hollow cylinder is fixed on the internal thread. The height of the cylindrical hollow cylinder is not less than 200mm, and the cylindrical hollow cylinder has an external thread, which can be detachably installed with the internal thread of the ring 53. After the cylindrical hollow cylinder is installed, the length of the tail of the anchor cable that is restrained can be increased, thereby greatly reducing the range of the anchor cable swinging until no injury occurs; when the anchor cable does not need to be clamped, the cylindrical hollow cylinder is removed and the ring 53 is flipped to the operating table 51.

[0049] In order to ensure the operating range of the drilling and anchoring part 2, that is, to effectively ensure the operating range of anchoring, clamping and delivering anchor cables and lifting I-beams, and to maximize the function of the single-arm anchor drilling vehicle, see Figure 1 、 Figure 3 and Figures 5 to 8 The vertical lifting assembly 4 includes a base 41, a lifting bracket 42 and a lifting cylinder 43. A slide rail 411 is provided on the base 41. The lifting cylinder 43 drives the lifting bracket 42 to move up and down along the slide rail 411 with the base 41 as support. The vertical lifting assembly 4 can drive the drilling and anchoring part 2 to move up and down as a whole, thereby expanding the operating range of anchoring, clamping anchor cables and lifting I-beams; the lifting bracket 42 is L-shaped, and the rotary assembly 5 is provided at the end of the lifting bracket 42. The rotary assembly 5 includes a rotary cylinder 54 and a connecting seat 55. The rotary cylinder 54 is movably provided on the connecting seat 55, and the connecting seat 55 is fixed to the end of the lifting bracket 42. A translation cylinder 551 is provided on the connecting seat 55. The translation cylinder 551 drives the rotary cylinder 54 to move in translation with the connecting seat 55 as support, and the rotary cylinder 54 drives the drilling and anchoring part 2 to move in translation as a whole;

[0050] A first L-shaped connecting plate 541 is provided at the end of the rotary cylinder 54; a second L-shaped connecting plate 213 is provided on the drill arm support frame 211, and the first L-shaped connecting plate 541 and the second L-shaped connecting plate 213 are hinged; a front and rear swing angle cylinder 542 is provided at the bottom of the first L-shaped connecting plate 541, and the front and rear swing angle cylinder 542 drives the second L-shaped connecting plate 213 to swing with the first L-shaped connecting plate 541 as a fulcrum, thereby driving the drilling and anchoring part 2 to swing slightly back and forth, with a swing range of ±8°, so as to achieve fine-tuning of the position of the drilling and anchoring part 2, and increase the flexibility and accuracy of anchoring, clamping anchor cables and lifting I-beams.

[0051] See also Figures 1 to 4 The body of the single-arm anchor drilling vehicle is narrow and light. When the drilling and anchoring part 2 is raised to a higher position to drive the anchor, the body is prone to tilting. To avoid this,

[0052] An outer cylinder 414 is provided on both sides of the base 41, and an inner cylinder 415 is provided in the outer cylinder 414. A vertical cylinder 416 drives the inner cylinder 415 to rise and fall with the outer cylinder 414 as support. A supporting leg 412 is provided on the top of the inner cylinder 415. The supporting leg 412 and the inner cylinder 415 are hinged. A folding cylinder 413 is provided on one side of the supporting leg 412. The folding cylinder 413 drives the supporting leg 412 to fold or stand upright with the inner cylinder 415 as a support point; when it is necessary to support the top of the tunnel, the folding cylinder 413 drives the supporting leg 412 to stand upright. If the height of the supporting leg 412 itself is not enough, the vertical cylinder 416 is started to lift the inner cylinder 415 to further increase the height of the supporting leg 412; when it is not necessary to support the top of the tunnel, the folding cylinder 413 drives the supporting leg 412 to fold to prevent the supporting leg 412 from occupying space.

[0053] Through this embodiment, by cooperating with a single-arm anchor drilling vehicle with a body width of 900mm-1200mm and a bridge-type loader, the single-arm anchor drilling vehicle drives anchors, clamps anchor cables and lifts I-beams on the side of the bridge-type loader, realizing the coordination of anchoring operations in a small space and improving operating efficiency.
