[0002] Drilling is a crucial step in the construction of hydropower stations, laying the foundation for anchoring, drainage, and other structural support measures. Traditional drilling equipment often relies on manual adjustments and fixing devices to ensure accurate borehole positioning, which is not only inefficient but also difficult to guarantee work quality in complex terrain or environments requiring high precision. With the development of engineering technology, the increasing demands for drilling accuracy, operational safety, and work efficiency have spurred the research and application of more intelligent and automated borehole positioning devices.
[0003] Traditional drilling rigs typically rely on manual adjustments to determine the drilling position. This method is limited by the operator's experience and skill level. Manually setting the reference point and aligning the drilling position is difficult and prone to errors. If the drilling position is inaccurate, the anchors cannot be installed correctly, affecting the structural stability, and may even require re-drilling, increasing costs and time.

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0028] This embodiment provides, for example Figures 1 to 6 The diagram shows a drilling rig installation and positioning device for hydropower station construction, comprising a drilling rig 1, track wheel sets 2 connected to both sides of the drilling rig 1, a main shaft 3 located at the drilling end of the drilling rig 1, a connecting sleeve 4 extending longitudinally through the bottom end of the main shaft 3, a protective cover 5 connected to the bottom end of the connecting sleeve 4, and a spiral drill blade 6 disposed in the protective cover 5 and connected to the bottom end of the main shaft 3 through the connecting sleeve 4. An installation and positioning assembly 7 is provided around the drilling rig 1. The installation and positioning assembly 7 includes a drilling positioning ring 11 laid flat on the ground below the spiral drill blade 6, a positioning crossbeam 8 fixed to the outer wall of the drilling positioning ring 11, two positioning clamping longitudinal beams 9 slidably mounted on the inner wall of the positioning crossbeam 8 and located on both sides of the drilling positioning ring 11, and a relative drive mechanism disposed in the positioning crossbeam 8. The relative drive mechanism synchronously drives the two positioning clamps. The longitudinal beam 9 moves centripetally and is clamped on the outer wall of the two track wheel sets 2. The drilling positioning ring 11 is aligned with the drilling position of the auger blade 6 to ensure the drilling operation position. Thus, the positioning clamping longitudinal beam 9 and the drilling rig 1 are based on the drilling positioning ring 11. The two positioning clamping longitudinal beams 9 clamp the track wheel sets 2 to reduce the movement of the drilling rig 1, thereby ensuring the accuracy of the drilling operation position of the auger blade 6. The top surface of the positioning crossbeam 8 is also provided with a multi-directional lifting positioning component 13. The force-applying working end of the multi-directional lifting positioning component 13 is connected to the connecting sleeve 4 and the protective cover 5, so that the lifting of the connecting sleeve 4 and the protective cover 5 can be bidirectionally positioned to prevent the positioning of the installation positioning component 7 from being inaccurate when the position of the connecting sleeve 4 and the protective cover 5 is offset, thereby further improving the positioning accuracy.
[0029] In this embodiment, mounting side plates 10 are welded to the bottom of the outer walls of the positioning crossbeam 8 and the two positioning clamping longitudinal beams 9. Each mounting side plate 10 is installed on the ground by multiple anchor rods 12.
[0030] In this embodiment, a rectangular groove 21 is provided in the middle of one side of the positioning beam 8 facing the drilling positioning ring 11. The relative driving mechanism includes a double-ended screw 23 rotatably installed in the rectangular groove 21, external thread teeth 24 provided on both sides of the double-ended screw 23 with opposite thread directions, and a servo motor 14 fixed to the outer wall of one end of the positioning beam 8.
[0031] In this embodiment, one end of the double-ended screw 23 extends to the outside of the positioning beam 8 and is connected to the output shaft of the servo motor 14. The two external threaded passages 24 of the double-ended screw 23 are threaded through the sliders 22, and the two sliders 22 are positioned and slid in the rectangular groove 21.
[0032] In this embodiment, the ends of the two sliders 22 away from the external threaded passages 24 are respectively fixedly connected to one end of the two positioning and clamping longitudinal beams 9. The servo motor 14 drives the double-ended screw 23 in the forward direction, which, under the design of the two external threaded passages 24, drives the two sliders 22 to move centripetally, thereby causing the two positioning and clamping longitudinal beams 9 to clamp the track wheel assembly 2 centripetally. When the servo motor 14 drives the double-ended screw 23 in the reverse direction, the two external threaded passages 24 cause the two sliders 22 to move in opposite directions, thereby causing the two positioning and clamping longitudinal beams 9 to release their clamping of the track wheel assembly 2.
[0033] In this embodiment, the drilling end of the drilling rig 1 is provided with a positioning vertical shaft rail 16, and the multi-directional lifting positioning component 13 includes a clamping positioning plate 15 clamped on one side of the protective cover cylinder 5, a T-shaped fixing sleeve 20 fixedly sleeved on the periphery of the connecting sleeve 4, two positioning vertical rods 18 symmetrically welded to the top surface of the positioning crossbeam 8, and a lifting crossbeam 19 longitudinally penetrating the two positioning vertical rods 18.
[0034] In this embodiment, the end of the T-shaped fixing sleeve 20 away from the connecting sleeve 4 is welded to the inner wall of the lifting crossbar 19.
[0035] In this embodiment, the end of the clamping positioning plate 15 away from the protective cover cylinder 5 is longitudinally engaged and slidably connected to the positioning vertical shaft track 16. When the connecting sleeve 4 and the protective cover cylinder 5 move up and down, the clamping positioning plate 15 slides longitudinally on the positioning vertical shaft track 16, while the T-shaped fixing sleeve 20 drives the lifting crossbar 19 to slide longitudinally on the two positioning vertical rods 18, thereby enabling longitudinal positioning of the connecting sleeve 4 and the protective cover cylinder 5 on symmetrical sides.
[0036] In this embodiment, a power distribution box 17 is installed on the top surface of the positioning beam 8. The power distribution box 17 has a PLC for controlling the opening and closing of the servo motor 14. The lifting and lowering of the connecting sleeve 4 and the protective cover 5, as well as the rotation and drilling of the auger blade 6, are all controlled by the controller in the drilling machine 1.
[0037] Working principle
[0038] The drilling rig used in the construction of the hydropower station is equipped with a positioning device. The crawler wheel sets 2 on both sides of the drilling rig 1 are used to move the entire drilling rig to the predetermined working position. After reaching the designated position, the entire device is firmly fixed to the ground by installing side plates 10 and anchor bolts 12, so that the drilling rig will not be displaced due to external forces during operation, thereby ensuring the accuracy of the drilling position.
[0039] The drilling positioning ring 11 is placed on the ground below the auger blade 6 and precisely aligned with the position to be drilled. The drilling positioning ring 11 provides a physical reference point for precise positioning in subsequent steps. The servo motor 14 is started, and the servo motor drives the double-ended screw 23 to rotate. Since the double-ended screw 23 has external thread teeth 24 with opposite directions on both sides, the slider 22 moves inward or outward in the rectangular groove 21. When the slider moves inward, it will drive the positioning clamping longitudinal beam 9 to clamp the track wheel set 2, thereby reducing the displacement of the drill 1 during the drilling process.
[0040] The multi-directional lifting and positioning assembly 13 enables the connection sleeve 4 and the protective cover 5 to maintain stability and verticality during the drilling process, preventing them from shifting due to external forces.
[0041] The PLC in the distribution box 17 is used to control the operating status of the servo motor 14 to achieve automated operation. In addition, the rotation of the spindle 3 and the lifting of the connecting sleeve 4 and the protective cover 5 are precisely controlled by the controller inside the drilling machine. After all the above preparations are completed, the drilling operation begins. The spindle 3 drives the spiral drill blade 6 to rotate and drill. During this process, the clamping positioning plate 15 slides longitudinally along the positioning vertical shaft track 16, while the T-shaped fixing sleeve 20 drives the lifting crossbar 19 to slide longitudinally on the positioning vertical rod 18 to ensure the stability and accuracy of the drilling process.
[0042] Once drilling is complete, stop the rotation of the main shaft 3, release the positioning clamping longitudinal beam 9, release the clamping of the track wheel assembly 2, and move the entire equipment to the next work location via the track wheel assembly 2 to prepare for the next use.
