[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] This utility model discloses a precision positioning drilling device for water conservancy construction, such as... Figure 1-5 As shown, it includes a fixed frame 1 and a drilling rod 4 installed inside the fixed frame 1, which is used for precise positioning drilling during water conservancy construction to explore underground resources during the water conservancy construction process.

[0022] Multiple limiting rods 401 are slidably connected to one side of the inside of the drilling rod 4, and the limiting rods 401 can move.

[0023] A contact plate 403 is fixedly installed at one end of the limiting rod 401 inside the drilling rod 4. A spring 402 is fixedly installed on one side of the contact plate 403, and the spring 402 is fixedly connected to the inner wall of the drilling rod 4. When the contact plate 403 compresses the spring 402, the contact plate 403 will push the limiting rod 401 to move, so that it extends out of the drilling rod 4. When the compressed spring 402 pushes the contact plate 403 to reset, the extended limiting rod 401 will retract into the drilling rod 4.

[0024] A drive plate 404 is slidably connected to one side of the inside of the drill rod 4. A first electric push rod 405 is fixedly installed on one side of the inner top surface of the drill rod 4, and the output end of the first electric push rod 405 is fixedly connected to the drive plate 404. The first electric push rod 405 pushes the drive plate 404 to rise and fall. When the drive plate 404 moves, it can contact multiple contact plates 403 in sequence and push the contact plates 403 to compress the spring 402. Then, when the drive plate 404 rises and falls, multiple limit rods 401 can extend out of the outside of the drill rod 4 in sequence.

[0025] The bottom of the drilling rod 4 is provided with a drill bit 412. A fixed ring 406 is fixedly installed on the bottom of the outer surface of the drilling rod 4. A movable ring 407 is rotatably connected inside the fixed ring 406. The movable ring 407 can rotate. Two connecting sleeves 408 are fixedly installed on the bottom surface of the movable ring 407. Connecting holes 409 are opened on both sides of the outer surface of the two connecting sleeves 408. A combination rod 413 is rotatably connected to the bottom of the drilling rod 4. A motor that drives the combination rod 413 to rotate is provided inside the drilling rod 4.

[0026] Two mounting rods 410 are fixedly installed on the top surface of the drill bit 412, and mounting holes 411 are opened on both sides of the outer surface of the two mounting plates. A combination hole 414 is opened on the top surface of the drill bit 412. The combination rod 413 is inserted into the combination hole 414, and the two mounting plates are inserted into the two connecting sleeves 408, so that the mounting hole 411 and the connecting hole 409 are overlapped. Then, the bolt is inserted into the overlapped connecting hole 409 and mounting hole 411, and the drill bit 412 can be installed. At this time, the combination rod 413 rotates, which can drive the drill bit 412 to rotate, so as to realize the drilling operation.

[0027] A hydraulic cylinder 3 is fixedly installed on the outer top surface of the fixed frame 1, and the output end of the hydraulic cylinder 3 is fixedly connected to the top surface of the drill rod 4. The hydraulic cylinder 3 can push the drill rod 4 to rise and fall, and cooperate with the rotating drill bit 412 to realize the drilling operation.

[0028] A limiting plate 5 is fixedly installed inside the fixed frame 1, and a limiting hole 6 is opened in the middle of the top surface of the limiting rod 401. The drilling rod 4 passes through the limiting hole 6. When the limiting rod 401 extends out of the outside of the drilling rod 4, the drilling rod 4 descends, so that the limiting rod 401 extending out of the outside of the drilling rod 4 contacts the top surface of the limiting plate 5, thereby preventing the drilling rod 4 from continuing to descend, and thus the descent distance of the drilling rod 4 can be controlled.

[0029] Two second electric push rods 101 are fixedly installed on the bottom surface of the limiting plate 5, and a protective ring 102 is fixedly installed on the output end of the two second electric push rods 101. The second electric push rods 101 can push the protective ring 102 to rise and fall. The bottom surface of the fixed frame 1 is provided with four universal self-locking wheels 2, and the position of the fixed frame 1 can be adjusted by the four universal self-locking wheels 2.

[0030] The inner bottom surface of the protective ring 102 has four movable holes 1021. Four movable blocks 1022 are slidably connected inside the protective ring 102 through the four movable holes 1021. A protective plate 1024 is fixedly installed at one end of each of the four movable blocks 1022 that passes through the movable holes 1021. A drive rod 1023 is fixedly installed on one side of each of the four movable blocks 1022 located inside the protective ring 102.

[0031] An adjusting plate 1025 is rotatably connected inside the protective ring 102. Four adjusting holes 1026 are provided on the top surface of the adjusting plate 1025, and a drive rod 1023 is movably connected to the adjusting holes 1026. A gear ring 1027 is fixedly installed on the top surface of the adjusting plate 1025. A gear 1028 is rotatably connected to one side of the inside of the protective ring 102, and the gear 1028 meshes with the gear ring 1027. A micro motor for driving the gear 1028 to rotate is provided inside the protective ring 102. Rotating 1028 causes the gear ring 1027 to rotate, which in turn causes the adjusting plate 1025 to rotate. This, in turn, moves the four drive rods 1023 and the movable block 1022, adjusting the position of the four protective plates 1024. The four protective plates 1024 can contact the inner wall of the borehole top to support the inner wall of the borehole top plate, effectively preventing the inner wall of the borehole top from collapsing during drilling.

[0032] The cross-sections of the four protective plates 1024 are all arc-shaped, which allows the arc-shaped protective plates 1024 to fit better against the inner wall of the borehole.

[0033] The working principle of this utility model is as follows: the hydraulic cylinder 3 can push the drilling rod 4 to descend through the limiting hole 6 until the rotating drill bit 412 contacts the ground to drill. During this process, the first electric push rod 405 pushes the drive plate 404 to move. The moving drive plate 404 will contact multiple contact plates 403 in sequence, which will cause multiple contact plates 403 to squeeze multiple springs 402 in sequence. When the contact plate 403 squeezes the spring 402, it can push the limiting rod 401 to extend out from the drilling rod 4. As the drilling rod 4 descends, the extended limiting rod 401 can contact the limiting plate 5. By the limiting rod 401 at different heights contacting the limiting plate 5, the descent distance of the drilling rod 4 can be controlled so as to accurately control the drilling depth.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
