However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0023] Reference Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a tunnel excavation construction device, which includes a first adjustment component, a second adjustment component, a third adjustment component, and a drilling component, thereby improving the efficiency of preparation work before tunnel blasting and ensuring drilling accuracy and safety.

[0024] Specifically, the first adjustment component includes a column 1 and a connecting frame 3 rotatably mounted on the top of the column 1. An arc groove 9 is formed on the upper side wall of the column 1 with the rotation point of the connecting frame 3 as the center. A fixing bolt 11 is provided on the outside of the column 1, penetrating the arc groove 9 and threadedly connected to the connecting frame 3. A base 2 is connected to the bottom of the column 1. A first scale line 10 is provided on the outer surface of the column 1 around the arc groove 9. The connecting frame 3 rotates relative to the column 1 to adjust the circumferential position of its upper end. With the first scale line 10, the rotation angle of the drilling component can be accurately adjusted. Rotating the fixing bolt 11 fixes the connecting frame 3 relative to the column 1. The first adjustment component will not move when the drilling component is in operation.

[0025] The second adjustment component includes a support plate 4. The upper end of the connecting frame 3 is circular. The support plate 4 is rotatably disposed inside the upper end of the connecting frame 3. An annular groove 12 is formed on the inner circumferential surface of the upper end of the connecting frame 3. The end of the support plate 4 is located inside the annular groove 12 and is slidably connected. The inner wall of the annular groove 12 is provided with an anti-slip texture 13 in an annular array. The end of the support plate 4 is provided with a limit member. The support plate 4 rotates relative to the connecting frame 3 along the annular groove 12, thereby adjusting the position of the support plate 4, that is, adjusting the position of the drilling component.

[0026] The limiting component includes a positioning block 16. The end of the support plate 4 is provided with a receiving groove 15. The positioning block 16 is located inside the receiving groove 15 and is radially slidably connected. A spring 17 is connected between the positioning block 16 and the inner bottom of the receiving groove 15. The outer surface of the support plate 4 is provided with a guide hole 18 that communicates with the receiving groove 15. A lever 19 that penetrates the guide hole 18 is connected to the outer wall of the positioning block 16. Under the push of the spring 17, the positioning block 16 contacts the anti-slip texture 13 of the annular groove 12. The positioning block 16 generates great resistance, thereby fixing the support plate 4 relative to the connecting frame 3. When the drilling assembly is working, the second adjustment assembly will not move. Under the external drive, the lever 19 drives the positioning block 16 to compress the spring 17 and thus be stored in the receiving groove 15, so that the second adjustment assembly can be operated.

[0027] The third adjustment component includes a cylinder base 6. The outer surface of the support plate 4 has a mounting hole 5 along its length. The cylinder base 6 is located inside the mounting hole 5 and is slidably connected. The outer surface of the support plate 4 has a second scale line 14 along the mounting hole 5. The outer wall of the cylinder base 6 is provided with a limiting plate 20 that fits against the front and rear surfaces of the support plate 4. The outer wall of the limiting plate 20 is threaded with a fastening bolt 21. The cylinder base 6 is prevented from separating from the support plate 4 by the limiting plate 20. The position of the drilling component is adjusted by moving the cylinder base 6 along the mounting hole 5. The displacement distance of the drilling component can be accurately adjusted by cooperating with the second scale line 14. The fastening bolt 21 is rotated to fix the limiting plate 20 and the support plate 4 relative to each other. The third adjustment component will not move when the drilling component is in operation.

[0028] The drilling assembly includes a drill bit 7 installed inside a cylinder base 6. A telescopic cylinder 8 is installed at the rear end of the cylinder base 6. The telescopic end of the telescopic cylinder 8 is connected to the drill bit 7. The telescopic cylinder 8 enables the drill bit 7 to move back and forth, and drills at the target location through the drill bit 7, providing a foundation for tunnel blasting construction.

[0029] During use, the operator first adjusts the connecting frame 3 of the first adjustment component according to the construction requirements, selects a suitable angle to determine the drilling position; then adjusts the support plate 4 in the second adjustment component to further adjust the direction and position of the drilling component; finally, the cylinder seat 6 of the third adjustment component is used to move and achieve fine-tuning alignment, so that the drilling component is accurately aligned with the target drilling point. After the drilling is positioned, the fastening mechanisms of the three sets of adjustment components are tightened respectively to achieve all-round locking, ensuring the stability and accuracy of the structure during drilling operations. The telescopic cylinder 8 is activated to control the drill 7 to move forward, and the drilling operation can be performed.

[0030] In summary, the combined design of the three sets of adjustment components enables the drilling assembly to achieve high-precision adjustment in multiple dimensions, allowing it to accurately align with drilling targets at different positions and angles. This meets the diverse and high-precision requirements for blasting hole positions in tunnel construction. Each adjustment component of the device is equipped with a limit mechanism and scale indication, making it easy to operate, highly accurate in adjustment, and reliable in positioning.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
