Description

Technical Field

[0001] This utility model belongs to the field of building construction equipment technology, specifically, it relates to a guiding and positioning device for the construction of drainage holes in venting tunnels. Background Technology

[0002] In the construction of underground engineering projects such as water conservancy and hydropower, and transportation tunnels, drainage tunnels are crucial drainage and safety facilities. To ensure their long-term stable operation, the tunnel body usually needs to be equipped with a systematic drainage system to release water pressure inside the surrounding rock and prevent damage to the lining structure due to excessive water load. Currently, the construction of drainage holes in drainage tunnels (mainly radial or oblique drilling) generally relies on manual operation of simple drilling frames or handheld equipment, which has the following main technical limitations: Low positioning accuracy and poor adjustment efficiency: The position and angle (especially the pitch angle) of the drainage holes require precision, which directly affects the drainage effect. Existing methods mostly use visual inspection combined with simple measuring tools for preliminary positioning, and then manually adjust and tighten multiple bolts to fix the drilling rig angle. This process is cumbersome and time-consuming, and depends on the operator's experience. It is difficult to achieve fast and accurate repeatable positioning, especially when carrying out multi-row and multi-hole sequence construction, where efficiency is low and consistency is difficult to guarantee. Unstable equipment fixation and inconvenient movement: The construction site is usually the tunnel floor, with limited space and potentially uneven ground. Traditional methods often use sandbags, temporary welding supports, or simple tripods to fix the drilling rig, which are not stable enough. Vibration and displacement are easily generated during drilling, causing the drilling axis to deviate and affecting the quality of the hole. At the same time, it is difficult to switch between these fixing methods and the moving state of the equipment. Each hole needs to be fixed again after complex work is carried out, resulting in poor mobility and seriously affecting the overall construction progress. To address the aforementioned issues, this application proposes a guiding and positioning device for constructing drainage holes in venting tunnels. Utility Model Content

[0003] In view of the problems in the related technologies, this utility model proposes a guiding and positioning device for the construction of drainage holes in venting tunnels, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A guiding and positioning device for constructing drainage holes in venting tunnels includes a base, a support plate fixedly mounted on the top of the base, a fixing ring fixedly mounted on the top of the support plate, an installation plate rotatably connected inside the fixing ring, a fixing plate fixedly mounted on one side of the installation plate, a drilling machine slidably mounted on one side of the fixing plate, a sliding groove formed on one side of the fixing plate, a moving block slidably connected to the inner wall of the sliding groove, the moving block being fixedly connected to the drilling machine, and a lead screw rotatably connected to the inner wall of the sliding groove, the lead screw being threadedly connected to the moving block, a drive motor fixedly mounted on the top of the fixing plate, the output shaft of the drive motor being fixedly connected to the lead screw, and a handle mounted on one side of the installation plate. An angle positioning mechanism includes a fixed base, which is fixedly installed on one side of the mounting plate, and a push rod is slidably connected to the fixed base, the push rod being engaged with a fixed ring for pushing. The fixed support mechanism includes four support rods, which are slidably mounted on a base. The bottom of the base is rotatably connected to four symmetrically arranged rotating wheels, which cooperate with the support rods.

[0005] Preferably, the angle positioning mechanism further includes two locking blocks, and multiple locking teeth are fixedly installed on the inner side of the fixing ring, with the locking blocks engaging with the locking teeth.

[0006] Preferably, a positioning plate is fixedly installed on the top rod, a top spring is fixedly installed at the bottom of the positioning plate, the bottom end of the top spring is fixedly connected to the fixed seat, and a push plate is fixedly installed at the bottom end of the top rod.

[0007] Preferably, the top of the base is slidably connected to four symmetrically arranged movable plates, which are driven by corresponding support rods. The top of the base is also slidably connected to two drive plates. A bidirectional screw is rotatably connected to the support plate, and the bidirectional screw is threadedly connected to the two drive plates. A connecting rod is fixedly installed on the side of each drive plate that is far apart from each other, and the connecting rod is fixedly connected to the corresponding movable plate.

[0008] Preferably, a sloping groove is provided on one side of the movable plate, and a movable shaft is fixedly installed on one side of the support rod, with the movable shaft slidably connected to the sloping groove.

[0009] Preferably, two guide rails are fixedly installed on one side of the fixing plate, and the guide rails are slidably connected to the drilling machine.

[0010] In summary, the technical effects and advantages of this utility model are as follows: By engaging the locking blocks with multiple locking teeth on the inner side of the fixing ring, the relative angle between the mounting plate and the fixing ring can be precisely locked, ensuring that the drilling angle of the drilling machine is stable and controllable, and avoiding angle deviation during construction. Under the pushing action of the top spring and the positioning plate, the push rod can automatically drive the locking blocks and locking teeth to engage, without the need for additional locking operations. Simply push the push plate to quickly release the locking state, realizing flexible adjustment of the drilling angle and greatly improving construction efficiency.

[0011] Through the transmission action of the bidirectional screw, the drive plate moves in the opposite direction. Then, through the linkage of the connecting rod and the moving plate, and the sliding cooperation of the inclined groove and the movable shaft, the four support rods move downward synchronously, quickly and firmly supporting the device on the construction ground. This effectively avoids the shaking and slippage of the rotating wheel caused by uneven ground or construction vibration, providing a stable operating platform for drilling operations and reducing drilling deviations and construction safety hazards caused by device displacement.

Angle positioning mechanism 7 includes a fixed seat 71, which is fixedly installed on one side of the mounting plate 4, and a push rod 72 is slidably connected to the fixed seat 71. The push rod 72 is engaged with the fixed ring 3. The fixed support mechanism 8 includes four support rods 81, which are slidably mounted on the base 1. The bottom of the base 1 is rotatably connected to four symmetrically arranged rotating wheels 9, which cooperate with the support rods 81.

[0016] Reference Figure 2 and Figure 5 The angle positioning mechanism 7 also includes two locking blocks 75. Multiple locking teeth 74 are fixedly installed on the inner side of the fixing ring 3. The locking blocks 75 and the locking teeth 74 are engaged. A positioning plate 76 is fixedly installed on the top rod 72. A top spring 77 is fixedly installed at the bottom of the positioning plate 76. The bottom end of the top spring 77 is fixedly connected to the fixing seat 71. A push plate 78 is fixedly installed at the bottom end of the top rod 72. Through the engagement of the locking blocks 75 and the multiple locking teeth 74, the angle between the mounting plate 4 and the fixing ring 3 can be fixed. At the same time, under the push of the positioning plate 76 and the top spring 77, the top rod 72 can automatically drive the locking blocks 75 and the locking teeth 74 to engage. The locking state can be released by the push plate 78.

[0017] Reference Figure 1Four symmetrically arranged movable plates 82 are slidably connected to the top of the base 1. The movable plates 82 are connected to the corresponding support rods 81. Two drive plates 83 are slidably connected to the top of the base 1. A bidirectional screw 84 is rotatably connected to the support plate 2. The bidirectional screw 84 is threadedly connected to the two drive plates 83. A connecting rod is fixedly installed on the side of the two drive plates 83 that is far apart from each other. The connecting rod is fixedly connected to the corresponding movable plate 82. A slanted groove 86 is opened on one side of the movable plate 82. A movable shaft 87 is fixedly installed on one side of the support rod 81. The movable shaft 87 is slidably connected to the slanted groove 86. The rotating bidirectional screw 84 is threadedly connected to the two drive plates 83, thereby driving the two drive plates 83 to move in opposite directions. The drive plates 83 drive the four movable plates 82 to move through the connecting rod. The movable plates 82 are slidably connected to the movable shaft 87 through the slanted groove 86, thereby driving the support rod 81 to move downward, thereby fixing and supporting the device and preventing the rotating wheel 9 from shaking back and forth.

[0018] Reference Figure 1 Two guide rails 14 are fixedly installed on one side of the fixed plate 5. The guide rails 14 are slidably connected to the drilling machine 6. By sliding with the drilling machine 6, the guide rails 14 can limit the drilling machine 6, thereby making the drilling machine 6 drill holes stably.

[0019] Working principle: During operation, rotating the bidirectional screw 84, which is threadedly connected to two drive plates 83, causes the two drive plates 83 to move in opposite directions. The drive plates 83, through connecting rods, drive four moving plates 82 to move. The moving plates 82 are slidably connected to the movable shaft 87 via inclined grooves 86, thereby causing the support rod 81 to move downwards. This provides fixed support for the device, preventing the rotating wheel 9 from wobbling back and forth, and pushing the push plate 78 downwards. This causes the push rod 72 to disengage the locking block 75 from the locking teeth 7. The mounting plate 4 is in the clamping state, and the mounting plate 4 is rotated. The mounting plate 4 drives the drilling machine 6 to align with the drilling position through the fixing plate 5. Then the push plate 78 is released. Under the pushing action of the top spring 77 and the positioning plate 76, the push rod 72 drives the clamping block 75 and the clamping tooth 74 to clamp again, so as to fix the angle of the adjusted mounting plate 4. Then the drive motor 13 switch is turned on. The output shaft of the drive motor 13 drives the lead screw 11 to rotate. The lead screw 11 is connected to the moving block 12 by a thread, so as to drive the drilling machine 6 to perform drilling operation on the target.
