[0003] In the prior art, the authorization announcement number is: CN220133920U, and the name is: A drilling anti-deviation device for drilling engineering. The utility model has a reasonable and reliable structure and is easy to operate, so that the spiral drill rod can be replaced and disassembled more conveniently after the drilling work is completed. At the same time, it can stabilize the support plate, and through the extension and shortening of the hydraulic telescopic rod 2, the stability and safety of the spiral drill rod during work are improved, thereby improving the stability and adaptability of the drilling anti-deviation device.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figure 1 - Figure 4 This embodiment proposes a drilling anti-deviation device, including a base plate 1 and an adjustment plate 2, an adjustment mechanism 3 is provided between the base plate 1 and the adjustment plate 2, the adjustment mechanism 3 includes two electric push rods 301 fixedly connected to the upper surface of the base plate 1, and the top ends of the two electric push rods 301 are fixedly connected to the bottom surface of the adjustment plate 2.

[0026] By providing the electric push rod 301, the height of the adjustment plate 2 can be easily adjusted, thereby being able to adapt to the working requirements of drill rods of different sizes.

[0027] L-shaped plates 302 are fixedly connected to both sides of the upper surface of the base plate 1, and two guide columns 303 are fixedly connected to the top of each L-shaped plate 302. The bottom surfaces of the four guide columns 303 are fixedly connected to the upper surface of the base plate 1, and the two sides of the adjustment plate 2 are slidably mounted on the outer surfaces of the four guide columns 303 respectively.

[0028] By providing the L-shaped plate 302 and the guide column 303, the adjustment plate 2 can be made more stable during the up and down movement, and the probability of the adjustment plate 2 shaking and becoming unstable can be reduced, which is beneficial to the stable drilling work.

[0029] A synchronous controller 304 is disposed outside the base plate 1 . The synchronous controller 304 is fixedly connected to the outer surface of the corresponding L-shaped plate 302 . Both of the two electric push rods 301 are electrically connected to the synchronous controller 304 .

[0030] By setting up the synchronous controller 304, the opening or closing of the two electric push rods 301 can be synchronously controlled, so as to facilitate the adjustment of the height of the adjustment plate 2 to meet different drilling requirements.

[0031] An anti-deviation mechanism 4 is provided inside the adjustment plate 2, and the anti-deviation mechanism 4 includes a turntable 401 rotatably mounted on the inner wall of the adjustment plate 2 and a worm gear assembly 402 fixedly connected to the outer surface of the turntable 401, as well as a worm 403 and a servo motor 404 installed on the upper surface of the adjustment plate 2, the worm 403 is meshed with the worm gear assembly 402, and the output shaft end of the servo motor 404 is fixedly connected to the rotating shaft end of the worm 403.

[0032] The shape of the turntable 401 is as follows Figure 4 As shown, the distribution state of the worm gear assembly 402 can be Figure 4 It is understood that the turntable 401 can rotate in the inner wall of the adjustment plate 2.

[0033] When the servo motor 404 is started, the worm 403 is driven to rotate. When the worm 403 rotates, the turntable 401 can be rotated through the worm gear assembly 402 meshing therewith. The worm 403 and the worm gear assembly 402 are combined to have the effects of deceleration and self-locking.

[0034] The deceleration effect can prevent the drill pipe body from being damaged due to excessive speed, and the self-locking effect can prevent the turntable 401 from rotating at will. The turntable 401 can only be driven to rotate by the worm 403, and the turntable 401 cannot drive the worm 403 to rotate in the reverse direction, thereby achieving a limit adjustment effect on the turntable 401.

[0035] A through opening 9 is provided on the upper surface of the bottom plate 1 and is located directly below the turntable 401 . The through opening 9 can facilitate the drilling work of the drilling head on the ground.

[0036] Three sleeve blocks 405 are rotatably sleeved on the upper surface of the turntable 401, and a clamping rod 406 is slidably sleeved on the inner wall of each sleeve block 405. One end of the three clamping rods 406 is hinged to the upper surface of the adjustment plate 2 through a pin shaft, and a ball 407 is installed on the side of the three clamping rods 406 that are close to each other.

[0037] When the turntable 401 rotates, the sleeve block 405 is driven to rotate together, and then the corresponding clamping rod 406 is driven to rotate, so that the three clamping rods 406 move closer to or away from each other. The rotation of the three clamping rods 406 can be used to stably clamp rotating rods of different sizes. In combination with the installed ball 407, the ball 407 is in contact with the surface of the drill rod, which can achieve a more stable anti-deviating effect.

[0038] A cover plate 408 is provided above the turntable 401 . The cover plate 408 is fixedly connected to the turntable 401 through three pillars on the upper surface of the turntable 401 . The top ends of the three sleeve blocks 405 are rotatably connected to the bottom surface of the cover plate 408 .

[0039] The cover plate 408 can be provided to reinforce the components installed on the surface of the turntable 401, so that the device is more stable when performing the anti-deviation work.

[0040] Four positioning seats 5 are fixedly connected to the outer surface of the bottom plate 1 , a threaded cone 6 is threadedly connected to the interior of each positioning seat 5 , and a handle 7 is fixedly connected to the top end of each threaded cone 6 .

[0041] By providing the positioning seat 5, the threaded cone 6 and the handle 7, the four threaded cones 6 can be inserted into the ground during drilling work to fix the device, thereby preventing the device from deviating when used on uneven ground.

[0042] Universal wheels 8 are installed at the four corners of the bottom surface of the base plate 1. A limiting mechanism is provided inside each universal wheel 8. By providing the universal wheels 8, the device can be flexibly moved, which is convenient for drilling work in different places.

[0043] Working principle: First, the device should be moved to the specified position, and then the four handles 7 are turned respectively to insert the four threaded cones 6 into the ground respectively, and then the drill rod is inserted into the turntable 401 from top to bottom, and the two electric push rods 301 are operated by operating the synchronous controller 304 to synchronize the operation to adjust the height of the turntable 401. After adjusting the height of the turntable 401, the servo motor 404 can be driven to work. When the servo motor 404 is started, it will drive the worm 403 to rotate. When the worm 403 rotates, the turntable 401 can be rotated through the worm gear assembly 402 meshing therewith. When the turntable 401 rotates, it will drive the sleeve block 405 moves, which can make the corresponding clamping rod 406 rotate, so that the three clamping rods 406 can move towards or away from each other, so that drill rods of different sizes can be clamped between the three clamping rods 406, and the ball 407 provided in combination can improve the anti-deviation effect of the clamping rod 406. At the same time, since the servo motor 404 and the worm 403 are combined together to have the effects of deceleration and self-locking, the turntable 401 will not rotate randomly, and the drill rod body can be stably clamped. The effect of positioning the device on the ground with the four threaded cones 6 can effectively reduce the probability of the drill rod being offset, which is more practical.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
