[0002] In tunnel boring engineering, the drill-and-blast method is a commonly used construction method. It involves drilling, charging explosives, and blasting to excavate the tunnel. The drill rod, as a key component in drilling operations, is typically quite long to accommodate tunnels of varying depths and widths. However, in existing technologies, long drill rods often suffer from instability during rotary drilling due to a lack of effective support in the middle. This instability not only reduces drilling accuracy and efficiency but can also lead to drill rod damage, increasing construction costs and safety risks. Therefore, we propose an improvement: a drill-and-blast tunnel boring device. Utility Model Content

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] For an example, please refer to... Figures 1-3A drilling and blasting tunnel boring machine includes a vehicle body 1 and a lifting mechanism 2 mounted on the vehicle body 1. A drilling mechanism 3 is mounted on the lifting mechanism 2. The drilling mechanism 3 includes a support member connected to the lifting mechanism 2, a support platform 304 connected to the support member, a slide table 311 slidably mounted on the outer surface of the support platform 304, a drive unit between the slide table 311 and the support platform 304, a carrier frame 312 mounted on the slide table 311, and a third drive motor 313 mounted on the carrier frame 312. The output shaft of the third drive motor 313 is connected to a drill rod body 314. Slide grooves 316 are provided on both sides of the support platform 304, and second limiting sliders 320 are slidably connected in both slide grooves 316. A sliding frame 318 is connected between the two limiting sliders 320. A support roller 319 is provided on the sliding frame 318, and the outer surface of the support roller 319 contacts the drill rod body 314. The sliding frame 318 and the support roller 319 provided in this application can support the middle part of the drill rod body 314, thereby improving the stability of the drill rod body 314 during rotation and improving the accuracy and efficiency of drilling. The sliding frame 318 is connected to the slide groove 316 through the second limiting slider 320, so that the position of the sliding frame 318 can be moved. Therefore, when the support frame 312 reaches the sliding frame 318, it can push the sliding frame 318 to move, so as to prevent the sliding frame 318 from affecting the further movement of the third drive motor 313.

[0029] A damping block is installed on the side of the sliding frame 318 near the support platform 304. The damping block contacts the side of the support platform 304. The damping block can be made of rubber. The damping block is used to limit the sliding frame 318 to prevent the sliding frame 318 from sliding on its own when the support platform 304 is tilted.

[0030] Furthermore, such as Figures 1-3 As shown, a positioning frame 315 is installed at the top of the support platform 304 near the lifting mechanism 2, and the outer surface of the drill rod body 314 is interlocked with the positioning frame 315. The positioning frame 315 can support the end of the drill rod body 314 away from the third drive motor 313, further improving the stability of the drill rod body 314 during use.

[0031] Furthermore, such as Figure 1 As shown, the drive unit includes two rotating shafts 305 mounted on the support platform 304 via bearings. Synchronous pulleys 306 are fixedly sleeved on the outer surfaces of the two rotating shafts 305. A synchronous belt 308 is connected between the two synchronous pulleys 306. Both ends of the synchronous belt 308 are connected to the slide table 311 by bolts. During the rotation of the synchronous pulleys 306, the slide table 311 can be driven to move horizontally through the synchronous belt 308, thereby driving the third drive motor 313 to move horizontally.

[0032] Furthermore, such as Figure 1 and Figure 3As shown, a second drive motor 307 is mounted on the side of the support platform 304. The output shaft of the second drive motor 307 is connected to one end of one of the rotating shafts 305. The second drive motor 307 can drive the rotating shaft 305 connected to it to rotate, thereby driving the synchronous pulley 306 to rotate.

[0033] Furthermore, such as Figure 1 As shown, a first limiting slider 317 is installed on the inner wall of both sides of the slide table 311. The outer surface of the first limiting slider 317 is slidably connected to the inner wall of the slide groove 316. The first limiting slider 317 and the slide groove 316 cooperate with each other to limit the slide table 311, thereby improving the stability of the slide table 311 during movement.

[0034] Furthermore, such as Figures 1-2 As shown, the lifting mechanism 2 includes a support frame 201 mounted on the vehicle body 1. A first drive motor located inside the vehicle body 1 is mounted on the bottom of the support frame 201. A lifting screw 202 is connected between the output shaft of the first drive motor and the support frame 201. A lifting seat 203 is threadedly connected to the outer surface of the lifting screw 202, and the lifting seat 203 is connected to the support member. The lifting seat 203 is slidably connected to the inner wall of the support frame 201. The first drive motor can drive the lifting seat 203 to rise and fall through the lifting screw 202, and then drive the support platform 304 to rise and fall through the support member, so as to adjust the height of the drill rod body 314 and realize the adjustment of the drilling height.

[0035] Furthermore, such as Figures 1-3 As shown, the support includes a first connecting seat 301 installed on the side of the lifting seat 203. A connecting shaft 302 is fixedly installed inside the first connecting seat 301. A second connecting seat 303 is sleeved on the outer surface of the connecting shaft 302. The second connecting seat 303 is installed at the bottom of the support platform 304. The second connecting seat 303 and the first connecting seat 301 can be connected together through the connecting shaft 302. The support platform 304 can rotate around the connecting shaft 302, thereby adjusting the angle of the support platform 304 to adjust the drilling angle of the drill rod body 314.

[0036] Furthermore, an adjusting member is provided between the first connecting seat 301 and the support platform 304, and the adjusting member is used to adjust the angle of the support platform 304.

[0037] Furthermore, such as Figures 1-3 As shown, the adjusting component includes a connecting frame 309 installed at the bottom of the support platform 304. A hydraulic cylinder 310 is hinged between the connecting frame 309 and the first connecting seat 301. The hydraulic cylinder 310, the connecting frame 309 and the first connecting seat 301 cooperate with each other to drive the support platform 304 to rotate, thereby adjusting the angle of the support platform 304.

[0038] Furthermore, such as Figure 4As shown, a counterweight 101 is installed on the top of the vehicle body 1 on the side away from the lifting mechanism 2. The counterweight 101 is used to counterweight the vehicle body 1 to balance the center of gravity shift of the vehicle body 1 during operation.

[0039] The process of using the drill-and-blast tunneling device provided by this utility model is as follows:

[0040] The first drive motor drives the lifting seat 203 to rise and fall via the lifting screw 202, which in turn drives the support platform 304 to rise and fall via the support member to adjust the height of the support platform 304. Then, the hydraulic cylinder 310, the connecting frame 309 and the first connecting seat 301 cooperate to drive the support platform 304 to rotate to adjust the angle of the support platform 304. Then, the second drive motor 307 drives the synchronous pulley 306 and the synchronous belt 308 via the rotating shaft 305 connected to it, which in turn drives the bearing frame 312 to move towards the positioning frame 315. The third drive motor 313 drives the drill rod body 314 to rotate to perform drilling. During the drilling process, the middle part of the drill rod body 314 can be supported by the sliding frame 318 and the support roller 319 to improve the stability of the drill rod body 314 during rotation.
