[0043] A driving mechanism 6, disposed on the control bracket 5, and the drill pipe 3 is connected to the driving mechanism 6;

[0044] A positioning and releasing mechanism 7, disposed in the control bracket 5 and the driving mechanism 6. The positioning and releasing mechanism 7 is used to fix and release the anchor rod 2.

[0045] As Figure 1 and Figure 6As shown, in the embodiment of the present invention, the drill pipe 3 is of a hollow rod structure, and the anchor rod 2 is arranged inside the drill pipe 3. One end of the anchor rod 2 is detachably connected with a drill bit 9, and the drill bit 9 cooperates with the drill pipe 3.

[0046] When the drilling and grouting equipment for tunnel construction is in use, the vehicle carrier 1 will drive the equipment to move to the side wall of the tunnel. Subsequently, the rotating mechanism 4 can adjust the drilling angle of the drill pipe 3 according to the drilling requirements. Then, the anchor rod 2 is first inserted into the drill pipe 3, and the positioning and releasing mechanism 7 fixes the anchor rod 2. Then, a disposable drill bit is installed at one end of the anchor rod 2. Subsequently, the driving mechanism 6 can drive the drill pipe 3 to rotate for drilling operations.

[0047] After the drill pipe 3 enters the wall, the driving mechanism 6 is controlled to operate in reverse. During the operation, the driving mechanism 6 will pull out the drill pipe 3, and the positioning and releasing mechanism 7 will automatically release the clamping of the anchor rod 2, so that the anchor rod 2 will remain in the wall. And during the process of pulling out the drill pipe 3, grouting operations can be carried out into the wall simultaneously, with a high degree of automation.

[0048] As Figures 1 to 8 shown, in the embodiment of the present invention, the driving mechanism 6 includes:

[0049] A chute 61 is arranged on the control bracket 5. A control block 62 is slidably arranged inside the chute 61. One side of the control block 62 is connected with a main motor 63, and the output end of the main motor 63 is connected with the drill pipe 3.

[0050] A driving motor 64 is arranged inside the control block 62. The output end of the driving motor 64 is connected with a first gear 65. A first rack 66 is arranged inside the chute 61, and the first gear 65 meshes with the first rack 66.

[0051] During use, the driving motor 64 will drive the first gear 65 to rotate, and then drive the control block 62 to move through the cooperation with the first rack 66. At the same time, the main motor 63 will drive the drill pipe 3 to continuously rotate to achieve drilling operations.

[0052] As Figures 1 to 8 shown, in the embodiment of the present invention, the positioning and releasing mechanism 7 includes:

[0053] A fixed platform 71 is arranged on the main motor 63. A driving column 72 is rotatably connected inside the fixed platform 71 through a rotary spring. The driving column 72 passes through the inside of the main motor 63. One end of the driving column 72 located inside the fixed platform 71 is provided with a threaded disc 73.

[0054] A plurality of slots 74 are opened on the fixed table 71. A slider 75 is slidably arranged inside each of the plurality of slots 74. A threaded slot 76 is arranged on one side of the slider 75, and the threaded slot 76 cooperates with the threaded disc 73.

[0055] A clamping plate 77 is installed on the slider 75, and the clamping plate 77 cooperates with the anchor rod 2.

[0056] A power assembly is arranged inside the control block 62, and the power assembly is used to control the rotation of the driving column 72.

[0057] When the driving column 72 rotates, the slider 75 will be driven to move in the slot 74 through the cooperation between the threaded disc 73 and the threaded slot 76, thereby adjusting the distance between the clamping plates 77. Therefore, when in use, under the action of the return spring, the rotational force of the driving column 72 will always give the clamping plates 77 a force to approach each other, and the clamping of the anchor rod 2 is realized through this effect.

[0058] As Figures 1 to 8 shown, in the embodiment of the present invention, the power assembly includes:

[0059] A telescopic cylinder 78 is rotatably arranged inside the control block 62. The telescopic end of the telescopic cylinder 78 is connected with a first bevel gear 79. One end of the driving column 72 is provided with a second bevel gear 710, and the first bevel gear 79 cooperates with the second bevel gear 710.

[0060] A telescopic column 711 is slidably and rotatably connected to one end of the telescopic cylinder 78. One end of the telescopic column 711 is rotatably installed with a second gear 712, and the second gear 712 is slidably connected with the telescopic column 711. A second rack 713 is installed on the side wall of one side of the chute 61, and the second rack 713 meshes with the second gear 712.

[0061] A switching assembly is arranged inside the control block 62, and the switching assembly is used to automatically adjust the extension length of the telescopic column 711.

[0062] As Figures 1 to 8 shown, in the embodiment of the present invention, the switching assembly includes:

[0063] A group of inclined sliding tables 714 are respectively installed on both sides of the telescopic column 711, and the group of inclined sliding tables 714 are arranged in a centrally symmetric manner.

[0064] A group of sliding rods 715 are respectively slidably arranged on both sides of the control block 62. The sliding rods 715 cooperate with the inner wall of the chute 61. One end of each of the group of sliding rods 715 is provided with a pulley 716, and the pulley 716 cooperates with the inclined sliding table 714.

[0065] As Figure 1 and Figure 5 shown, in the embodiment of the present invention, a grouting port 8 is provided on the side of the drill pipe 3, and the grouting port 8 is used to grout into the wall during the process of the drill pipe 3 completing drilling and being withdrawn.

[0066] After the driving mechanism 6 drives the drill pipe 3 into the wall, the control block 62 will move to the rightmost end of the sliding groove 61, then the side wall of the sliding groove 61 will push the sliding rod 715 on the right side of the control block 62, and the right sliding rod 715 will pass through the pulley 716 and, under the guiding action of the inclined sliding table 714 on the right side, squeeze and push the telescopic column 711 downward, so that the second gear 712 moves to the same plane as the second rack 713. Subsequently, first drive the telescopic cylinder 78 to push the first bevel gear 79 upward and engage it with the second bevel gear 710, and then reverse-control the operation of the driving mechanism 6 to move the control block 62 to the other side. Then, during the movement, the second gear 712 will drive the telescopic cylinder 78 to rotate under the action of the second rack 713, and further drive the driving column 72 to rotate by the cooperation between the first bevel gear 79 and the second bevel gear 710. At this time, the return spring connecting the driving column 72 is twisted, and the sliders 75 will move away from each other, releasing the clamping of the anchor rod 2 by the clamping plate 77. Then, under the action of gravity, the anchor rod 2 will remain in the wall, and the drill pipe 3 will be taken out;

[0067] After the drill pipe 3 is completely taken out, the anchor rod 2 will remain in the wall, and during the process of taking out the drill pipe 3, grouting can be carried out into the wall through the grouting port 8 on the drill pipe 3, which can accelerate the project progress, has simple operation, high automation degree, and is more convenient to use.

[0068] In summary, when the drilling and grouting equipment for tunnel construction is in use, the vehicle carrier 1 will drive the equipment to move to the side of the tunnel wall. Subsequently, the rotating mechanism 4 can adjust the drilling angle of the drill pipe 3 according to the drilling requirements. Then, first insert the anchor rod 2 into the drill pipe 3, the positioning and releasing mechanism 7 fixes the anchor rod 2, and then install a disposable drill bit at one end of the anchor rod 2. Subsequently, the driving mechanism 6 can drive the drill pipe 3 to rotate for drilling operation;

[0069] After the drill pipe 3 enters the wall, reverse-control the operation of the driving mechanism 6. Then, during the operation, the driving mechanism 6 will withdraw the drill pipe 3, and the positioning and releasing mechanism 7 will automatically release the clamping of the anchor rod 2. Then, the anchor rod 2 will remain in the wall, and grouting operation can be carried out into the wall simultaneously during the process of withdrawing the drill pipe 3, with high automation degree.

[0070] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
