Description

Technical Field

[0001] The present application relates to the technical field of tunnel boring directional tools, and more specifically, to a tunnel boring splitting free surface creation mechanism. Background Art

[0002] Blasting is one of the main methods for excavating stone surrounding rock tunnels. The main steps are to first use an air gun or a rock drill to drill blasting holes in the cross-section contour area, and then load explosives and other blasting materials. The shock waves and stress waves generated by the blasting of the explosives have a huge working force on the surrounding rocks, breaking the stone surrounding rocks, thereby achieving the excavation effect. The orientation of the tunnel drilling hole becomes a key factor affecting blasting excavation.

[0003] Some existing drilling tools are mainly operated by hand by workers, and the orientation during drilling is mainly estimated by the operator based on experience. In this way, it is difficult to accurately grasp the orientation angle during the drilling process, and it is easy to offset, which affects the opening angle. It is impossible to effectively control the accuracy of tunnel drilling and excavation, affecting the subsequent construction quality.

[0004] In order to solve the above problems, the present application provides a tunnel drilling splitting free surface creation mechanism. Utility Model Content

[0013] Furthermore, a slide groove is symmetrically provided at the top of the bearing plate, a slider is slidably connected inside the slide groove, and the top of the slider is arranged at the bottom end of the coupling.

[0029] Example:

[0030] The present application embodiment discloses a tunnel drilling splitting free surface creation mechanism, see Figure 1 , Figure 2 and Figure 3 , including a gun body 1, a reducer 2 is arranged on one side of the gun body 1, a coupling 3 is arranged on one side of the reducer 2, a drill bit 4 is arranged on one side of the coupling 3, a handle 8 is arranged on the other side of the gun body 1, a grip 9 is arranged at the bottom end of the gun body 1, and an auxiliary component is arranged at the bottom end of the gun body 1.

[0031] See also Figure 1 and Figure 2The auxiliary components include a bearing plate 10, a stop plate 11, a telescopic rod 12 and a stop block 14. The bearing plate 10 is arranged at the bottom end of the coupling 3, and the top end of the stop plate 11 is arranged on one side of the bottom end of the bearing plate 10.

[0032] Through the mutual cooperation between the internal structures, it can be ensured that the equipment can maintain a stable angle when drilling, avoiding deviation during the drilling process, thereby effectively controlling the drilling angle.

[0033] See also Figure 1 and Figure 2 A plurality of stop blocks 14 are evenly arranged inside the stop plate 11 , a connecting shaft 13 is arranged on the top of the stop block 14 , and an outer wall of the connecting shaft 13 is rotatably connected to an inner wall of the stop plate 11 .

[0034] A movable shaft is provided at the top of the butt plate 11, and the outer wall of the movable shaft is rotatably connected to the bottom end of the supporting plate 10. When in use, the butt plate 11 is rotated by the movable shaft so that the angle between the butt plate 11 and the supporting plate 10 reaches the desired angle, and then the butt plate 11 is contacted with the wall. The butt block 14 is rotatably connected to the butt plate 11 through the connecting shaft 13. When in use, the butt block 14 can be rotated open under the action of the connecting shaft 13.

[0035] See also Figure 1 and Figure 2 The telescopic rod 12 is arranged at the bottom end of the bearing plate 10 , a rotating shaft 15 is arranged at the top end of the telescopic rod 12 , and an outer wall of the rotating shaft 15 is arranged at the bottom end of the bearing plate 10 .

[0036] Here, the length of the telescopic rod 12 can be adjusted to meet the requirements of different angles of the auxiliary components.

At this time, with the cooperation of the telescopic rod 12, the support plate 11 and the supporting plate 10, a stable triangular area can be formed, which can play a good angle auxiliary role. During the drilling process, the slider 16 is used to ensure that the gun body 1 can stably move and drill on the top of the supporting plate 10, so that the drilling angle will not deviate.
