DETAILED DESCRIPTION

[0030] The following will be described in detail in combination with the accompanying Figures 1-2 The present application will be further described in detail.

[0031] The embodiments of the present application disclose a blast hole drilling equipment for tunnel construction. Referring to Figure 1 , which comprises a base 1, the bottom of the base 1 is provided with a roller 11, and the base 1 is fixedly installed with a combined slide rail 2. The combined slide rail 2 is slidably arranged along the width direction of the base 1 with a translation table 3. The translation table 3 is slidably arranged along the height direction of the base 1 with a lifting platform 4, specifically, a first air cylinder is fixedly arranged on the translation table 3 in the vertical direction, and the lifting platform 4 is fixedly connected with the output end of the first air cylinder. The lifting platform 4 is slidably arranged along the length direction of the base 1 with a drilling platform 5, and the drilling platform 5 is rotatably arranged with a drill bit 51 at the end of the length direction of the base 1, specifically, a second air cylinder is fixedly arranged on the lifting platform 4, and the drilling platform 5 is fixedly connected with the output end of the second air cylinder.

[0032] Referring to Figure 1When drilling holes at different width positions of the tunnel wall is needed, the base 1 does not need to be moved, and the position of the drill bit 51 in the width direction of the base 1 is adjusted by sliding the translation table 3 on the combined slide rail 2. The position of the drill bit 51 in the height direction of the base 1 is adjusted by the extension amount of the output end of the first air cylinder. Finally, the drill table 5 is driven to slide by the second air cylinder to drive the drill bit 51 to approach the wall, thereby drilling holes in the tunnel wall. This facilitates drilling holes at different width positions of the tunnel wall, reduces the operation of re-aligning the drill bit 51, and improves the drilling efficiency.

[0033] In order to facilitate the adjustment of the size of the combined slide rail 2 to adapt to tunnels of different widths, with reference to Figure 1 With Figure 2 , the combined slide rail 2 includes a plurality of slide rail nodes 21, all of which are connected in series along the width direction of the base 1, and adjacent slide rail nodes 21 are detachably connected. The two sides of one end of the slide rail node 21 are fixedly provided with a butt plug rod 22, and the two sides of the other end of the slide rail node 21 are fixedly provided with a butt seat 23. The butt seat 23 is provided with a butt slot 231 along the width direction of the base 1. The butt slot 231 is used for inserting the butt plug rod 22 of the adjacent slide rail node 21. The butt seat 23 is provided with a first positioning hole 232 along the height direction of the base 1. The butt plug rod 22 is provided with a second positioning hole 221 along the height direction of the base 1. The first positioning hole 232 and the second positioning hole 221 are jointly provided with a anti-dropping positioning pin 24. Any one or more slide rail nodes 21 are fixed on the base 1 by welding, so as to fix the combined slide rail 2 formed by the combination of the slide rail nodes 21 on the base 1. When installing the combined slide rail 2, the number of slide rail nodes 21 can be selected according to the actual needs of the width of the tunnel, so as to adapt to tunnels of different sizes and improve the versatility of the combined slide rail 2.

[0034] In order to facilitate the improvement of the bearing capacity of each slide rail node 21, with reference to Figure 2 , the two sides of the slide rail node 21 are fixedly provided with a downwardly extending fixed sleeve 25. The fixed sleeve 25 is provided with a sliding sleeve rod 251 at the bottom end. The sliding sleeve rod 251 is fixedly provided with a support plate 252 at the bottom. The fixed sleeve 25 and the sliding sleeve rod 251 are provided with an adjusting assembly 6. The adjusting assembly 6 is used for adjusting the extension length of the sliding sleeve rod 251 at the bottom of the fixed sleeve 25. The adjusting assembly 6 includes a nut block 61, a lead screw 62, and a knob 63. The nut block 61 is fixedly arranged at the top of the fixed sleeve 25. The middle part of the lead screw 62 is threadedly connected with the nut block 61. The top of the lead screw 62 is fixedly connected with the knob 63. The bottom of the lead screw 62 is rotatably connected with the top end of the sliding sleeve rod 251. During the operation of the device, the lead screw 62 is rotated by rotating the knob 63. The rotation of the lead screw 62 is converted into the up-down movement of the sliding sleeve rod 251 in the fixed sleeve 25, so as to adjust the extension length of the sliding sleeve rod 251, and then the support plate 252 is in contact with the ground of the tunnel, thereby improving the bearing capacity of each slide rail node 21.

[0035] In order to drive the translation platform 3 to slide along the combined slide rail 2, referring to Figure 1 With Figure 2 , the rack 26 is integrally formed on the combined slide rail 2 along the width direction of the base 1, and the driving motor 31 is fixedly arranged on the translation platform 3, and the driving shaft of the driving motor 31 is coaxially fixed with the gear 311, and the rack 26 and the gear 311 are engaged with each other. Among them, the driving motor 31 is a servo motor. When it is needed to drive the translation platform 3 to slide along the combined slide rail 2, the driving motor 31 is started, the driving shaft of the driving motor 31 drives the gear 311 to rotate, and the gear 311 and the rack 26 are engaged with each other, thereby pushing the translation platform 3 to move along the combined slide rail 2.

[0036] The implementation principle of the drilling equipment for the blasting hole of the tunnel construction in the embodiment of the application is as follows: when the drilling operation of the blasting hole of the tunnel is performed, according to the actual width of the tunnel, a proper number of slide rail nodes 21 are selected to be spliced and assembled into the combined slide rail 2. Then, the equipment is moved to a suitable construction position through the rollers 11 at the bottom of the base 1, and the knob 63 is rotated, the screw rod 62 is rotated to drive the sliding sleeve rod 251 to move downward, the supporting plate 252 of the slide rail node 21 is abutted against the ground, and the slide rail node 21 is supported. Finally, the drilling operation is performed.

[0037] In the drilling operation, the driving motor 31 drives the gear 311 to rotate on the rack 26, so that the translation platform 3 can be accurately moved along the width direction of the combined slide rail 2, thereby quickly adjusting the drill bit 51 to the width position of the tunnel wall surface that needs to be drilled. The height of the lifting platform 4 is adjusted by controlling the extension and retraction of the output end of the first cylinder, and then the position of the drill bit 51 in the height direction of the base 1 is determined. The drill platform 5 is driven to slide by the second cylinder, and the drill bit 51 is driven to approach the wall surface to perform the drilling operation. When drilling is needed at different width positions, the base 1 does not need to be moved, and the drilling can be performed at different width positions of the tunnel wall surface, the operation of re-aligning the drill bit 51 is reduced, and the drilling efficiency is improved.

[0038] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application shall be covered within the protection scope of the application.
