A positioning plate 2 is detachably connected to the end of the drill body 1. The length direction of the positioning plate 2 is perpendicular to the axial direction of the drill body 1. A processing hole 3 is opened on the positioning plate 2. The drill body 1 can be inserted into the processing hole 3 and the wall is processed. A first positioning rod 4 is fixed to the end of the positioning plate 2 by an integrated molding method. The axial direction of the first positioning plate 2 is parallel to the axial direction of the drill body 1. The end of the positioning plate 2 away from the first positioning rod 4 is fixed with a second positioning rod 6 by an integrated molding method. The axial direction of the second positioning rod 6 is parallel to the axial direction of the first positioning rod 4. During the construction process, the first positioning rod 4 and the second positioning rod 6 are inserted into the wall to fix the position of the positioning plate 2. At this time, the position of the processing hole 3 is fixed, and the drill body 1 is inserted into the processing hole 3 to construct the wall inside the tunnel.

[0033] Reference Figure 1 , Figure 2 and Figure 3 An adjusting cylinder 5 is slidably arranged on the first positioning rod 4, and the axial direction of the adjusting cylinder 5 is the same as the axial direction of the first positioning rod 4, and the adjusting cylinder 5 and the first positioning rod 4 are coaxially arranged, and the adjusting cylinder 5 can slide on the first positioning rod 4 along the axial direction of the first positioning rod 4, and a mounting groove 17 is provided on the first positioning rod 4, and the inner wall of the adjusting cylinder 5 is fitted with the inner wall of the mounting groove 17, thereby reducing the possibility of the adjusting cylinder 5 being separated from the first positioning rod 4, and at the same time, the ends of the first positioning rod 4 and the second positioning rod 6 are provided with positioning guide surfaces, which are convenient for the first positioning rod 4 and the second positioning rod 6 to be inserted into the wall, the outer wall diameter of the adjusting cylinder 5 is larger than the outer wall diameter of the first positioning rod 4, and the outer wall of the adjusting cylinder 5 is provided with an adjustment guide surface, It is convenient to insert the adjustment tube 5 into the wall inside the tunnel. At the same time, the length of the second positioning rod 6 is shorter than the length of the first positioning rod 4. During the construction process, the first positioning rod 4 is inserted into the wall while the adjustment tube 5 is inserted into the wall. When it is necessary to process the next hole, the first positioning rod 4 is pulled out. At this time, the adjustment tube 5 continues to remain inside the wall, the positioning plate 2 is rotated to a suitable position, and the first positioning rod 4 and the second positioning rod 6 are re-inserted into the wall, and the next processing can be carried out. Since the position of the adjustment tube 5 does not change, the distance between the two processings is the same, which is convenient for positioning adjacent holes. The length of the second positioning rod 6 is shorter than the length of the first positioning rod 4, which facilitates the rotation process of the positioning plate 2.

[0034] Reference Figure 1 , Figure 2 and Figure 3, the positioning plate 2 is detachably connected with a support frame 7 by bolt fixing, and a control hole 8 is opened on the support frame 7, and the control hole 8 passes through the support frame 7, and a control rod 9 is slidably arranged in the control hole 8, and the end of the control rod 9 is fixed to the end of the drill body 1 by bolt fixing, and the drill body 1 can be driven to move by driving the control rod 9 to process the wall; a control groove 10 is opened on the side wall of the control rod 9, and a limit plate 18 is fixed on the inner wall of the control hole 8 by an integral molding method, and the limit plate 18 abuts against the inner wall of the control groove 10, so that the control rod 9 will not be separated from the control hole 8. At the same time, a control spring 11 is arranged in the control groove 10, and one end of the control spring 11 abuts against the inner wall of the control groove 10, and the other end abuts against the limit plate 18. The control spring 11 is used to push the control rod 9 to move in the direction away from the positioning plate 2, so that after the operation control rod 9 drives the drill body 1 to complete the drilling construction, the drill body 1 can quickly separate from the wall, which is convenient for the drilling construction process.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the adjusting cylinder 5 is fixed with a plurality of limit rods 12 by an integral molding method. The plurality of limit rods 12 are evenly distributed around the axis of the adjusting cylinder 5. The limit rods 12 are used to limit the position of the adjusting cylinder 5, reducing the possibility of the adjusting cylinder 5 rotating. At the same time, a limited guide surface 13 is provided on the limit rod 12 to facilitate the limit rod 12 to penetrate into the wall. The side wall of the adjusting cylinder 5 is provided with a plurality of limit grooves 14, and the limit grooves 14 are connected to the bottom of the adjusting cylinder 5. A certain angle is spaced between two adjacent limit grooves 14, and the angle is adjusted according to the construction requirements. The positioning plate 2 is fixed with a limiting block 15 by an integral molding method, and the limiting groove 14 is used to penetrate the limiting block 15. The limiting block 15 is penetrated in the limiting groove 14 to adjust the position of the positioning plate 2, and the adjustment of the processing hole 3 is completed, thereby completing the adjustment of the hole opening position, which is convenient for the drilling positioning process; in addition, a support ring 16 is fixed on the support frame 7 by bolts, and the drill body 1 is penetrated in the support ring 16. The support ring 16 plays a limiting role, reducing the possibility of the drill body 1 being offset during the drilling construction process.

[0036] The implementation principle of a tunnel blasting drilling positioning device in an embodiment of the present application is as follows: the first positioning rod 4 is penetrated into the wall while the adjusting tube 5 is penetrated into the wall. When the next hole needs to be processed, the first positioning rod 4 is pulled out, and the adjusting tube 5 continues to remain inside the wall. The positioning plate 2 is rotated to a suitable position, and the first positioning rod 4 and the second positioning rod 6 are re-inserted into the wall. The next processing can be carried out. Since the position of the adjusting tube 5 does not change, the distance between the two processings is the same, which is convenient for positioning adjacent holes.
