[0005] The above solution still has the following problems: The above scheme requires a large amount of reusable materials (such as fasteners) when erecting the scaffold, and it needs to be frequently erected and dismantled along the length of the rock wall beam, which is wasteful of materials and time and labor. Furthermore, when facing drilling holes with different inclination angles, the angle of the guide pipe needs to be adjusted when erecting the scaffold. If the scaffold is not erected in a standardized manner, the angle of the guide pipe will not meet the requirements. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an auxiliary drilling device for inclined rock wall beams, which can solve the technical problems of time-consuming and labor-intensive scaffolding construction and difficulty in controlling the angle of the guide pipe in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An inclined rock wall beam-assisted drilling device includes a rectangular frame structure, the rectangular frame structure includes a rectangular frame, the rectangular frame is connected to a telescopically adjustable vertical support rod, and a positioning structure is connected to the rectangular frame.

Then, the height of the rectangular frame relative to the vertical support rod is adjusted to raise the guide tube to the corresponding elevation, guaranteeing precise drilling of inclined rock face beams. This avoids frequent scaffolding erection and facilitates flexible adjustment of the guide tube angle, enabling precise control of the guide tube angle and ensuring both construction progress and the quality of rock face beam excavation.

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses an auxiliary drilling device for inclined rock wall beams, such as... Figure 1 As shown, it includes a rectangular frame structure 1, and a positioning structure 2 is connected to the rectangular frame structure 1. The positioning structure 2 is used to install the drill rod.

[0022] In this embodiment, the rectangular frame structure 1 is a height-adjustable structure. By adjusting the height of the rectangular frame structure 1, the height of the positioning structure 2 on the rectangular frame structure 1 can be adjusted, thereby adjusting the elevation of the drill rod installed on the positioning structure 2. The positioning structure 2 is an angle-adjustable structure. Adjusting the angle of the positioning structure 2 relative to the rectangular frame structure 1 can adjust the angle of the drill rod relative to the rectangular frame structure 1, so that the drill rod can be aligned with the inclination angle of the inclined rock surface to be drilled.

[0023] Specifically, such as Figure 1 , Figure 4 As shown, the rectangular frame structure 1 includes a rectangular frame 11, which is connected to a telescopically adjustable vertical support rod 12, and a positioning structure 2 is connected to the rectangular frame 11.

[0024] like Figure 1 , Figure 2 As shown, the positioning structure 2 is a triangular positioning structure, including a horizontal rod 21. The two ends of the horizontal rod 21 are fixedly connected to (in this embodiment, both the horizontal rod 21 and the sleeve 22 are made of steel, and the fixed connection between the horizontal rod 21 and the sleeve 22 is achieved by welding) the sleeve 22; as shown Figure 1 As shown, the sleeve 22 is connected to the rectangular frame 11.

[0025] like Figure 1 , Figure 2 As shown, an upper inclined rod 23 is hinged to a sleeve 22 at one end of the horizontal rod 21, and the upper inclined rod 23 can rotate relative to the horizontal rod 21. In this embodiment, the middle section of the upper inclined rod 23 faces the horizontal rod 21, and the upper inclined rod 23 is hinged to one end of an adjusting inclined rod 24 (the adjusting inclined rod 24 can rotate relative to the upper inclined rod 23), while the other end of the adjusting inclined rod 24 is slidably connected to the horizontal rod 21.

[0026] In this embodiment, as Figure 2 , Figure 3 As shown, the adjusting rod 24 is hinged to a locking bolt 25 at one end facing the horizontal rod 21. Specifically, the locking bolt 25 includes a locking nut 251, with a locking screw 252 internally threaded onto the locking nut 251, and a rotating block 253 fixedly connected (which can be welded) to the outer periphery of the locking nut 251. A locking groove is formed at one end of the adjusting rod 24 that is hinged to the locking bolt 25 (i.e., the end of the adjusting rod 24 facing the horizontal rod 21), and the rotating block 253 is rotatably connected in the locking groove (a pin passes through both sides of the rotating block 253 and the locking groove, so that the rotating block 253 is rotatably connected to the locking groove).

[0027] like Figure 2As shown, a groove 211 is provided on the horizontal rod 21. The adjusting rod 24 and the locking nut 251 are located above the horizontal rod 21. The locking screw 252 passes through the groove 211 from below the horizontal rod 21 and is threadedly connected to the locking nut 251. By passing the locking screw 252 through the groove 211 and threading it to the locking nut 251, the adjusting rod 24 is connected to the horizontal rod 21 by frictional pressure, thus fixing the position of the adjusting rod 24 on the horizontal rod 21.

[0028] In this embodiment, as Figure 1 , Figure 2 As shown, a guide tube 26 is connected to the upper inclined rod 23. The guide tube 26 is a hollow tube and is parallel to the upper inclined rod 23. The drill rod is sleeved inside the guide tube 26, which provides angular guidance for the drill rod.

[0029] It is understood that, during drilling, the inclined rock wall beam auxiliary drilling device of this embodiment can adjust the angle of the upper inclined rod 23 relative to the horizontal rod 21 in advance according to the inclination angle of the hole to be drilled, so that the angle of the guide tube 26 is consistent with the inclination angle of the hole to be drilled. Then, the height of the rectangular frame 11 relative to the vertical support rod 12 is adjusted to raise the guide tube 26 with the adjusted angle to the corresponding elevation, ensuring the accuracy of drilling the inclined rock wall beam. This embodiment connects the rectangular frame structure 1 and the positioning structure 2 together, avoiding frequent scaffolding erection, and also facilitating flexible adjustment of the guide tube angle, achieving precise control of the guide tube angle.

[0030] like Figure 3 As shown, the bottom surface of the rotating block 253 is flush with the bottom surface of the locking nut 251, and both the bottom surfaces of the rotating block 253 and the locking nut 251 are in contact with the top surface of the horizontal rod 21. When the rotating block 253 and the locking nut 251 are moved, the rotating block 253 and the locking groove (adjusting rod 24) rotate relative to each other, thereby causing the end of the adjusting rod 24 facing the horizontal rod 21 to be hinged to the locking bolt 25.

[0031] In this embodiment, the length of the groove 211 is less than the length of the horizontal rod 21, and the groove 211 passes through the top and bottom surfaces of the horizontal rod 21.

[0032] In this embodiment, the width of the groove 211 is smaller than the diameter of the locking nut 251, the width of the groove 211 is equal to the diameter of the locking screw 252, and the diameter of the cap section of the locking screw 252 is larger than the width of the groove 211. The locking screw 252 is threaded through the groove 211 and connected to the locking nut 251, and tightened. The adjusting rod 24 is connected to the horizontal rod 21 by frictional pressure, thus fixing the position of the adjusting rod 24 on the horizontal rod 21.

[0033] Understandably, when it is necessary to adjust the angle of the upper inclined rod 23 relative to the horizontal rod 21, the locking screw 252 is loosened, allowing the adjusting rod 24 to move relative to the horizontal rod 21 until the angle of the upper inclined rod 23 relative to the horizontal rod 21 meets the requirements, and then the locking screw 252 is tightened.

[0034] like Figure 1 , Figure 2 As shown, in this embodiment, the guide tube 26 and the upper inclined rod 23 are connected by a movable connection, which facilitates replacement when the guide tube 26 needs to be replaced. For example, multiple stainless steel clamps and adjusting straps 27 can be used to connect guide tubes 26 of different diameters to the upper inclined rod 23. When replacement is needed, all the multiple stainless steel clamps and adjusting straps 27 are loosened, and after replacement, the multiple stainless steel clamps and adjusting straps 27 are tightened again.

[0035] like Figure 1 , Figure 4 As shown, in this embodiment, two rectangular frames 11 are arranged vertically (to ensure structural stability). Vertical support rods 12 are connected to the four corners of each rectangular frame 11. Each rectangular frame 11 includes two long rods 111 and two short rods 112. Figure 1 As shown, the sleeves 22 at both ends of the horizontal rod 21 of the positioning structure 2 are fitted onto the two long rods 111 of the upper rectangular frame 11.

[0036] like Figure 1 As shown, multiple positioning structures 2 are connected between the two long rods 111 of the upper rectangular frame 11, which can control the drilling angle of multiple holes to be drilled, facilitating construction. In this embodiment, two positioning structures 2 are connected.

[0037] like Figure 1 , Figure 4 As shown, the vertical support rod 12 is a three-section sleeve structure. The two ends of the middle sleeve 122 are slidably fitted inside the top sleeve 121 and the bottom sleeve 123, and the top sleeve 121 and the bottom sleeve 123 have the same diameter. The bottom end of the top sleeve 121 is fixedly connected to the corner of the rectangular frame 11 above it (e.g., by welding or riveting), and the top end of the bottom sleeve 123 is fixedly connected to the corner of the rectangular frame 11 below it (e.g., by welding or riveting). It can be understood that by sliding the top sleeve 121 and the bottom sleeve 123 relative to the middle sleeve 122, the height of the top sleeve relative to the ground can be adjusted, thereby adjusting the height of the rectangular frame 11 above it relative to the ground, and ultimately adjusting the height of the positioning structure 2 relative to the ground.

[0038] like Figure 4As shown, a track groove 124 is pre-reserved on the side of the middle sleeve 122. The length of the track groove 124 is less than the length of the middle sleeve 122, and the two ends of the track groove 124 do not coincide with the two ends of the middle sleeve 122. A fixing screw 125 is threadedly connected to the top of the bottom sleeve 123 and the bottom of the top sleeve 121, and the fixing screw 125 passes through the track groove 124. Tightening the fixing screw 125 causes the head of the fixing screw 125 to press against the inner wall of the middle sleeve 122. The fixing screw 125 fixes the relative position of the middle sleeve 122 with the bottom sleeve 123 or the top sleeve 121 through the force of pressure friction. Loosening the fixing screw 125 allows the bottom sleeve 123 or the top sleeve 121 to move relative to the middle sleeve 122. At this time, the fixing screw 125 of the bottom sleeve 123 or the top sleeve 121 slides relative to the track groove 124.

[0039] It is understandable that, such as Figure 4 As shown, the top sleeve and bottom sleeve are connected to the rectangular frame 11 as a whole. There are four top sleeves and four bottom sleeves. After the fixing screws are tightened, they can support the drill rod and assist the drill rod in drilling.

[0040] In this embodiment, when adjusting the height of the positioning structure 2 relative to the ground, the relative positions of the bottom sleeve and the middle sleeve can be adjusted first, and then the relative positions of the top sleeve and the middle sleeve can be adjusted. During adjustment, the upper rectangular frame 11 and the lower rectangular frame 11 are spaced apart, so that the two rectangular frames 11 form a stable support in space, ensuring the overall stability of the device.

[0041] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
