[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The power switching component enables the power connection between the pulley 2 and the output shaft. When the driving motor drives the output shaft to rotate, the pulley 2 rotates synchronously with the output shaft, and transmits the power to the pulley 1 in combination with the transmission belt. At this time, the pulley 1 drives the matching shaft 1 to rotate, so that the matching gear and the semicircular rack engage with each other. Under the limiting action of the matching slider 2, the pulley 1 moves along the semicircular frame 1. The moving pulley 1 carries the grouting mechanism connected to the side and moves along the clamping groove 2, thereby performing flexible grouting operations on the inner wall of the tunnel.

[0018] (2) When it is necessary to control the grouting mechanism to perform the grouting operation along the semicircular frame 1, the distance between the connecting plate and the semicircular frame 2 is adjusted by the telescopic motor, and then the pulley 2 and the matching shaft 2 are matched with each other in combination with the sliding plate. At this time, the power of the output shaft is transmitted to the pulley 2, and then the pulley 1 and the matching gear are driven to rotate, so that the matching gear and the semicircular rack are meshed with each other, and the grouting mechanism is carried out to perform the grouting operation. By setting an arc groove on the semicircular frame 2 and combining the connection ball with the telescopic motor, the transfer mechanism can realize the connection or disconnection between the power on the output shaft and the grouting mechanism at any position, thereby realizing the continuous grouting operation of the grouting mechanism at a certain position, or performing uniform grouting operation along the inner wall of the tunnel of a pair of semicircular frames.

[0019] (3) The swing motor 2 is used to control the folding of the swing rod 2 and the swing rod 1. At this time, the matching groove 1 on the swing rod 2 and the clamping protrusion on the inner side of the clamping frame are clamped with each other. Then, the swing motor 2 is continued to be controlled to fold the swing rod 1 and the swing rod 2 as a whole with the rotating rod until the clamping protrusion near the edge of the clamping frame and the matching groove 2 are matched with each other, completing the recovery and folding operation of the swing rod 1 and the swing rod 2.

[0020] (4) The slurry in the barrel is injected into the sealing sleeve 1, the output shaft, the sealing sleeve 2 through the delivery pump, and finally sent into the rotating rod until it reaches the nozzle. While the movement of the transfer mechanism is controlled by the sealing sleeve 1, the sealing sleeve 2, and the output shaft, the slurry can be continuously delivered to the grouting mechanism to avoid interference with the delivery pipeline during the transfer process of the transfer mechanism, effectively simplifying the slurry delivery line and improving the grouting efficiency.

[0056] The working principle of the embodiment of the present invention is:

[0057] like Figure 1-Figure 13As shown, the power switching component enables the power connection between the pulley 2 38 and the output shaft 21. When the driving motor 20 drives the output shaft 21 to rotate, the pulley 2 38 rotates synchronously with the output shaft 21, and transmits the power to the pulley 1 35 in combination with the transmission belt 36. At this time, the pulley 1 35 drives the matching shaft 1 33 to rotate, so that the matching gear 314 and the semicircular rack 3100 are engaged with each other. Under the limiting action of the matching slider 2 313, the pulley 1 35 moves along the semicircular frame 1 31, and the moving pulley 1 35 carries the grouting mechanism 4 connected to the side to move along the clamping groove 2 312, so as to perform flexible grouting operations on the inner wall of the tunnel. When it is necessary to control the grouting mechanism 4 to perform the grouting operation along the semicircular frame 1 31, the distance between the connecting plate 34 and the semicircular frame 2 32 is adjusted by the telescopic motor 322, and then the pulley 2 38 and the matching shaft 2 39 are matched with each other in combination with the sliding plate 37. At this time, the power of the output shaft 21 is transmitted to the pulley 2 38, and then the pulley 1 35 and the matching gear 314 are driven to rotate, so that the matching gear 314 and the semicircular rack 3100 are meshed with each other, and the grouting mechanism 4 is carried out to perform the grouting operation. The arc groove 321 is set on the semicircular frame 2 32, and the connection between the clamping ball 323 and the telescopic motor 322 can be combined to make the transfer mechanism 3 realize the connection or disconnection between the power on the output shaft 21 and the grouting mechanism 4 at any position, so as to realize the continuous grouting operation of the grouting mechanism 4 at a certain position, or to perform uniform grouting operation on the inner wall of the tunnel along the semicircular frame 1 31. The height adjustment capability of the grouting mechanism 4 is further enhanced by providing an extension rod 42. The length between the swing rod 1 41 and the extension rod 42 is controlled by the adjustment cylinder 410 and the connecting slide column 411, thereby adjusting the height of the end swing rod 2 43. At the same time, the distance between the nozzle 44 and the inner wall of the tunnel can be adjusted to adapt to the grouting operations of different types of slurries. In order to facilitate the recovery of the swing rod 1 41 and the swing rod 2 43 after the grouting is completed, a clamping frame 412 and a clamping protrusion 413 are set on the swing rod 1 41. After the grouting is completed, the extension rod 42 is first retracted in combination with the adjusting cylinder 410, and the swing rod 2 43 and the swing rod 1 41 are controlled to fold together by the swing motor 2 46. At this time, the matching groove 1 414 on the swing rod 2 43 and the clamping protrusion 413 on the inner side of the clamping frame 412 are clamped together, and then the swing motor 2 46 is continued to be controlled to make the swing rod 1 41 and the swing rod 2 43 folded as a whole with the rotating rod 40 until the clamping protrusion 413 near the edge of the clamping frame 412 and the matching groove 2 415 cooperate with each other, thereby completing the recovery and folding operation of the swing rod 1 41 and the swing rod 2 43.The slurry in the barrel 50 is injected into the sealing sleeve 1 53, the output shaft 21, and the sealing sleeve 2 54 through the delivery pump 51, and finally sent into the rotating rod 40 to the nozzle 44. While the movement of the transfer mechanism 3 is controlled by the sealing sleeve 1 53, the sealing sleeve 2 54, and the output shaft 21, the slurry can be continuously delivered to the grouting mechanism 4, avoiding interference with the delivery pipeline during the transfer process of the transfer mechanism 3, effectively simplifying the slurry delivery line, and improving the grouting efficiency.
