[0030] like Figures 1 to 4As shown, a tunnel blasting hole positioning device comprises a mounting frame 1 and a positioning line generating device, wherein a mounting vertical plate 2 is fixedly arranged on the mounting frame 1, a slide plate 3 is slidably arranged on the mounting vertical plate 2 in a vertical direction, a driving assembly is fixedly arranged between the slide plate 3 and the mounting frame 1, a positioning line alignment device is fixedly arranged on the slide plate 3, and a positioning point marking device is also fixedly arranged on the slide plate 3; the positioning line generating device comprises a positioning frame 4, a laser emitting device 5 is fixedly arranged on the positioning frame 4; the positioning line alignment device comprises a background plate 6 and a transparent member 7, the background plate 6 is fixedly connected to the slide plate 3, and the background plate 6 has a horizontal reference line 8 , the transparent member 7 is fixedly arranged on the background plate 6; when working, firstly, the positioning line generating device is fixed on the ground, so that the direction of the laser emitted by the laser emitting device 5 is the axial direction of the entire tunnel blasting hole layout, and at the same time, a cable parallel to the laser direction is pulled up on the ground, and then the mounting frame 1 is pushed along the direction of the cable, and the mounting frame 1 is stopped at intervals to determine the position of the blasting hole. The specific steps for determining the blasting hole are: the laser emitted by the laser emitting device 5 passes through the transparent member 7, leaving a light path inside the transparent member 7, and the height of the slide plate 3 is adjusted so that the light path coincides with the horizontal reference line 8 on the background plate 6, and the position of the blasting hole can be determined by the positioning point marking device.

[0031] The positioning point marking device is a laser pen 9 fixedly set on the slide plate 3; when working, when the light path coincides with the horizontal reference line 8 on the background plate 6, the laser pen 9 is turned on, and the position where the laser pen 9 falls on the inner wall of the tunnel is the position of the blasting hole, and a circle is drawn at the landing point to prepare for subsequent excavation.

[0032] A T-shaped slide groove 10 is provided on the mounting vertical plate 2, and the slide plate 3 is slidably set in the T-shaped slide groove 10; during operation, since the heights of the blasting holes in different tunnels are different, the height of the slide plate 3 is adjusted by sliding the slide plate 3, and the T-shaped slide groove 10 can also prevent the far end of the slide plate 3 from flipping downward.

[0033] The driving assembly includes a motor 11 fixedly arranged on the mounting frame 1, and a lead screw 12 is fixedly arranged at the output end of the motor 11. The lead screw 12 passes through the slide plate 3 and is threadedly connected to the slide plate 3. When working, the slide plate 3 is driven to slide up and down by the motor 11 and the lead screw 12.

[0034] An observation rod 13 is also fixedly provided on the background plate 6; when working, the horizontal reference line 8 is observed through the observation rod 13 to see whether it coincides with the light path. The arrangement requirements of the observation rod 13 are: it does not block the laser path, and the top of the observation rod 13 is equal to the height of the horizontal scale line 16.

[0035] A reference line 14 is also fixedly provided on the mounting frame 1, and the reference line 14 is parallel to the direction of the laser emitted by the laser emitting device 5. When working, the reference line 14 is used to align with the ground cable to prevent the mounting frame 1 from being offset when it is pushed along the laser path, thereby causing the landing point of the laser pen 9 to be offset.

[0036] A universal wheel assembly 15 is fixedly provided at the bottom of the mounting frame 1 ; during operation, the mounting frame 1 moves on the ground via the universal wheel assembly 15 .

[0037] The mounting plate 2 is also provided with scale lines 16; during operation, at a special position, the height of a certain blasting hole may need to be set individually. At this time, the height of the laser emitting device 5 needs to be adjusted, which is more troublesome and prone to errors. At this time, the height difference between the special blasting hole and the conventional blasting hole is calculated, and then the motor 11 drives the slide plate 3 to slide to the corresponding height. The height of the slide plate 3 can be accurately controlled by the scale lines 16.

[0038] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
