Description

Technical Field

[0001] The present application relates to the technical field of drilling equipment, and in particular to a drilling deviation correction device. Background Art

[0002] Drilling technology is widely used in geological exploration, resource exploitation and other fields. Drilling equipment is used to drill underground to obtain formation information or exploit underground resources.

[0003] During the drilling process, due to the complex stratum structure, the uneven distribution of rocks in the stratum and the different hardness at different positions, the borehole is prone to deviation. Therefore, every time a certain distance is drilled, workers are required to measure the borehole with an inclinometer. If the borehole deviates, the borehole needs to be corrected to avoid the borehole slope becoming larger and larger. Utility Model Content

[0004] In order to facilitate geological drilling, the present application provides a drilling deviation correction device.

[0005] The present application provides a drilling deviation correction device, which adopts the following technical solution:

[0006] A drilling deviation correction device comprises a drilling tower, a mounting block, a first drill rod, a second drill rod, a driving assembly and a deviation correction assembly; the drilling tower is vertically arranged; the mounting block is arranged on the drilling tower; a drill bit is arranged on the first drill rod; one end of the second drill rod is connected to the first drill rod, and the other end is connected to the mounting block; the driving assembly is arranged on the drilling tower, and is used to drive the mounting block to reciprocate up and down, and drive the drill bit to rotate; the deviation correction assembly is arranged on the drilling tower, and is used to correct the deviation of the drill hole.

[0007] By adopting the above technical solution, when conducting geological drilling, the driving assembly drives the drill bit to rotate and drives the mounting block to move downward, thereby driving the second drill rod, the first drill rod and the drill bit to feed downward, thereby drilling a hole underground. In this process, every time a certain distance is drilled, the operator uses an inclinometer to measure the inclination of the borehole. If the borehole deviates, the correction assembly is used to correct the borehole so that the borehole remains vertical again. After the correction is completed, drilling continues, realizing the correction of the borehole, thereby facilitating geological drilling.

[0008] Optionally, the driving assembly includes a first hydraulic telescopic rod and a driving motor; the first hydraulic telescopic rod is vertically arranged, the fixed end of the first hydraulic telescopic rod is fixedly connected to the drilling tower, and the movable end of the first hydraulic telescopic rod is connected to the mounting block; a guide assembly is provided on the drilling tower, and the guide assembly is used to guide the mounting block; the driving motor is fixedly arranged on the first drill rod; the drill bit is coaxially fixedly connected to the output shaft of the driving motor.

[0009] By adopting the above technical solution, when conducting geological drilling, the first hydraulic telescopic rod is controlled to be extended and retracted, thereby driving the mounting block to move up and down reciprocatingly. In this process, the guide assembly guides the mounting block to prevent the mounting block from deviating when moving. The drill bit is driven by the driving motor to rotate, cooperating with the first hydraulic telescopic rod to achieve drilling and feeding.

[0010] Optionally, the drill bit is evenly provided with at least three slide grooves along its circumference; the deviation correction assembly includes a reaming knife and an adjustment component; at least three reaming knives are provided, and correspond one-to-one with the slide grooves, the reaming knives are located in the slide grooves, and are slidably connected to the drill bit; the adjustment component is provided on the drill bit, and is used to adjust the relative position of the reaming knife and the drill bit.

[0011] By adopting the above technical scheme, if a drilling deviation is detected during geological drilling, the operator first drives the first hydraulic telescopic rod to extend, thereby driving the first drill rod, the second drill rod and the drill bit to be lifted upward to the position where the drilling hole was measured last time, and uses the adjusting component to adjust the relative position of the reaming knife and the drill bit so that the reaming knife extends out of the slide slot, and then starts the driving motor to drive the drill bit to rotate. The rotation of the drill bit drives the reaming knife to rotate, and the drill hole is expanded, and the inclined drill hole is expanded into a straight hole with a larger aperture, thereby realizing the correction of the drilling hole. After the drilling deviation is corrected, the relative position of the reaming knife and the drill bit is adjusted by the adjusting component, so that the reaming knife is retracted into the slide slot to prevent the reaming knife from affecting subsequent drilling operations, thereby facilitating geological drilling.

[0012] Optionally, the adjusting component includes a turntable and a reaming motor; the turntable is coaxially arranged inside the drill bit and is rotatably connected to the drill bit, a planar thread is arranged on the end face of the turntable, a planar thread is also arranged on the reaming cutter, and the planar thread on the turntable is engaged with the planar thread on the reaming cutter; the reaming motor is fixedly arranged on the drill bit and is used to drive the turntable to rotate.

[0013] By adopting the above technical scheme, when the reaming cutter needs to be extended for drilling deviation correction, the operator controls the reaming motor to rotate forward, thereby driving the turntable to rotate forward, driving the three reaming cutters to slide in the direction away from the axis of the drill bit, so that the reaming cutters extend out of the slide slot. When the drilling deviation correction is completed and the reaming cutter needs to be retracted, the operator controls the reaming motor to rotate reversely, thereby driving the turntable to rotate reversely, driving the three reaming cutters to slide in the direction close to the axis of the drill bit, and retracting the reaming cutters into the slide slot, thereby realizing the contraction of the reaming cutter.

[0014] Optionally, the correction assembly also includes a second hydraulic telescopic rod and a limiting arc plate; four second hydraulic telescopic rods are provided, the fixed ends of the second hydraulic telescopic rods are fixedly connected to the drilling tower, and the second hydraulic telescopic rods are evenly arranged along the circumference of the second drill rod; four limiting arc plates are provided, and are fixedly connected to the movable ends of the second hydraulic telescopic rods.

[0015] By adopting the above technical scheme, before using the reaming cutter to correct the borehole, the second hydraulic telescopic rod is first used to drive the limiting arc plate to slide in the direction close to the second drill rod until the limiting slide plate abuts against the second drill rod, thereby limiting the second drill rod to prevent the second drill rod from shifting during the process of the reaming cutter correcting the borehole, thereby ensuring the accuracy of the borehole expansion, thereby facilitating the correction of the borehole and facilitating geological drilling.

[0016] Optionally, a first mounting groove is provided at one end of the first drill rod away from the drill bit, and an internal thread is provided on the side wall of the first mounting groove; the second drill rod is provided with at least one, a joint is fixedly provided at one end of the second drill rod, and the second mounting groove is provided at the other end; an internal thread is also provided on the side wall of the second mounting groove, and an external thread is provided on the joint, and the external thread on the joint is adapted to the internal thread on the first mounting groove and the internal thread on the second mounting groove.

[0018] Optionally, a rod-changing motor and a rotating block are provided on the mounting block; the rod-changing motor is fixedly connected to the mounting block; the rotating block is coaxially fixedly connected to the output shaft of the rod-changing motor, and an external thread is provided on the rotating block, and the external thread on the rotating block is adapted to the internal thread in the second mounting groove.

[0019] By adopting the above technical solution, when conducting geological drilling, the operator first moves the second drill rod to the bottom of the mounting block, aligns the rotating block with the second mounting groove, and then uses the rod-changing motor to drive the rotating block to rotate, while the first hydraulic telescopic rod drives the mounting block to move downward until the rotating block is fixed to the second drill rod. Then, the operator moves the first drill rod to the bottom of the second drill rod, aligns the joint with the first mounting groove, and again uses the rod-changing motor to drive the rotating block and the second drill rod to rotate, while the first hydraulic telescopic rod drives the mounting block to move downward, so that the first drill rod and the second drill rod are fixed, thereby facilitating the installation of the first drill rod and the second drill rod, and thus facilitating geological drilling.

[0020] When installing the second drill rod and the first drill rod, the second hydraulic telescopic rod can be used to drive the limiting slide to move in the direction of approaching each other, so that the bottom of the second drill rod and the top of the first drill rod can be clamped and fixed, thereby eliminating the need for manual fixation of the first drill rod and the second drill rod, and can ensure the personal and property safety of the operator to a certain extent.

[0038] The following is combined with Figure 1-3 This application is described in further detail.

[0039] The present application embodiment discloses a drilling deviation correction device. Figure 1 A drilling deviation correction device includes a drilling tower 1, which is vertically fixed at a position to be drilled.

[0040] Reference Figure 2 and Figure 3 A driving assembly 5 is provided on the drilling tower 1, and the driving assembly 5 includes a first hydraulic telescopic rod 51, which is vertically arranged, the bottom of the fixed end of the first hydraulic telescopic rod 51 is fixed to the ground, and the top of the fixed end of the first hydraulic telescopic rod 51 is fixedly connected to the drilling tower 1.

[0041] Reference Figure 1 The drilling tower 1 is provided with a guide assembly 7, which includes a guide rod 71 and a slider 72. Two guide rods 71 ​​are provided, and are respectively located on both sides of the first hydraulic telescopic rod 51. The guide rods 71 ​​are vertically arranged and fixedly connected to the drilling tower 1. Both sides of the slider 72 are slidably connected to the two guide rods 71, respectively, and the sliding axis is vertically arranged. The bottom of the slider 72 is fixedly connected to the top of the movable end of the first hydraulic telescopic rod 51.

[0042] Reference Figure 1 and Figure 2 The slider 72 is fixed with a mounting block 2. The mounting block 2 is fixed with a rod-changing motor 21, the output shaft of which is vertically downwardly arranged, and a rotating block 22 is coaxially fixedly arranged on the output shaft of the rod-changing motor 21, and an external thread is arranged on the rotating block 22.

[0043] Reference Figure 2 and Figure 3 A drilling deviation correction device also includes a first drill rod 3 and a second drill rod 4. The driving assembly 5 also includes a driving motor 52, which is fixedly arranged inside the first drill rod 3. A drill bit 31 is coaxially arranged at one end of the first drill rod 3, and the drill bit 31 is coaxially and fixedly connected to the output shaft of the driving motor 52. A first mounting groove 32 is coaxially opened at the other end of the first drill rod 3, and an internal thread is arranged on the side wall of the first mounting groove 32. Several second drill rods 4 are arranged, and a second mounting groove 42 is coaxially opened at one end of the second drill rod 4, and the same internal thread is also arranged on the side wall of the second mounting groove 42. A joint 41 is coaxially and fixedly arranged at the other end of the second drill rod 4, and an external thread is arranged on the side wall of the joint 41, and the external thread on the joint 41 is adapted to the internal thread in the first mounting groove 32 and the second mounting groove 42.

[0044] Reference Figure 2 A rod-changing motor 21 is fixedly arranged on the mounting block 2, and the output shaft of the rod-changing motor 21 is arranged vertically downward. A rotating block 22 is coaxially fixedly arranged on the output shaft of the rod-changing motor 21, and the rotating block 22 is provided with an external thread, and the external thread on the rotating block 22 is adapted to the internal thread in the second mounting groove 42.

[0045] When conducting geological drilling, the operator first uses the rod changing device to move the second drill rod 4 to the bottom of the mounting block 2, so that the rotating block 22 is aligned with the second mounting groove 42, and then starts the rod changing motor 21, which drives the rotating block 22 to rotate, and at the same time, the first hydraulic telescopic rod 51 drives the mounting block 2 to move downward, until the rotating block 22 and the second drill rod 4 are fixed by the external thread on the rotating block 22 and the internal thread in the second mounting groove 42. Then, the operator moves the first drill rod 3 to the bottom of the second drill rod 4, so that the joint 41 is aligned with the first mounting groove 32, and starts the rod changing motor 21 again, which drives the rotating block 22 and the second drill rod 4 to rotate, and the first hydraulic telescopic rod 51 drives the mounting block 2 to move downward, so that the first drill rod 3 and the second drill rod 4 are fixed by the external thread on the joint 41 and the internal thread in the first mounting groove 32.

[0046] After the first drill rod 3 and the second drill rod 4 are installed, the operator starts the drive motor 52 and the first hydraulic telescopic rod 51. The drive motor 52 drives the drill bit 31 to rotate, and the first hydraulic telescopic rod 51 drives the slider 72 and the mounting block 2 to slide downward along the guide rod 71, thereby driving the first drill rod 3, the second drill rod 4 and the drill bit 31 to feed downward.

[0047] When the top of the second drill rod 4 is about to be fed into the ground, the rod-changing motor 21 is reversed to drive the rotating block 22 to rotate in the opposite direction. At the same time, the first hydraulic telescopic rod 51 drives the slider 72 and the mounting block 2 to move upward, so that the rotating block 22 is separated from the second drill rod 4. Then, the first hydraulic telescopic rod 51 is used to drive the slider 72 and the mounting block 2 to move upward and reset. When the slider 72 and the mounting block 2 move to the initial position, the operator uses the rod-changing equipment to move another second drill rod 4 to the bottom of the mounting block 2, repeats the installation process of the second drill rod 4, and fixes the two ends of the latter second drill rod 4 to the rotating block 22 and the previous second drill rod 4 respectively. At this time, the operator can start the drive motor 52 and the first hydraulic telescopic rod 51 to continue to feed the drilling downward.

[0048] Reference Figure 2 and Figure 3 The drilling tower 1 is provided with a deviation correction component 6, which includes a reaming cutter 61, an adjustment component 62, a second hydraulic telescopic rod 63 and a limiting arc plate 64. Three slide grooves 311 are evenly opened on the drill bit 31 along the circumference of its own axis, and the slide grooves 311 are arranged along the radial direction of the drill bit 31. There are three reaming cutters 61, which correspond to the slide grooves 311 one by one. One end of the reaming cutter 61 is located in the slide groove 311 and is slidably connected to the drill bit 31, and the sliding axis is arranged along the radial direction of the drill bit 31.

[0049] The adjusting component 62 includes a rotating disk 621 and a reaming motor 622. The rotating disk 621 is coaxially arranged inside the drill bit 31 and is rotatably connected to the drill bit 31, and the rotation axis is arranged along the axis of the drill bit 31. A flat thread is arranged on one end face of the rotating disk 621. A flat thread is also arranged on one side of the reaming cutter 61, and the flat thread on the reaming cutter 61 is engaged with the flat thread on the rotating disk 621. The reaming motor 622 is fixedly arranged inside the drill bit 31, and the output shaft of the reaming motor 622 is coaxially fixedly connected to the rotating disk 621.

[0050] Reference Figure 1 , four second hydraulic telescopic rods 63 and four limiting arc plates 64 are provided, the second hydraulic telescopic rods 63 correspond to the limiting arc plates 64 one by one, the second hydraulic telescopic rods 63 are arranged horizontally, the four second hydraulic telescopic rods 63 are evenly arranged along the circumferential direction of the axis of the rotating block 22, and the fixed end of the second hydraulic telescopic rod 63 is fixedly connected to the drilling tower 1. The limiting arc plate 64 is fixedly connected to the movable end of the second hydraulic telescopic rod 63.

[0051] When installing the second drill rod 4 and the first drill rod 3, the second hydraulic telescopic rod 63 is used to drive the limiting slide to move in the direction of approaching each other, so that the bottom of the second drill rod 4 and the top of the first drill rod 3 can be clamped and fixed, and then the rod changing motor 21 is started to drive the rotating block 22 to rotate.

[0052] During geological drilling, when the operator detects that the drilling hole has deviated, the operator first drives the first hydraulic telescopic rod 51 to extend, thereby driving the first drill rod 3, the second drill rod 4 and the drill bit 31 to be lifted upward to the position where the drilling hole was last measured, and then uses the second hydraulic telescopic rod 63 to drive the limiting arc plate 64 to slide in the direction close to the second drill rod 4 until the limiting slide plate abuts against the second drill rod 4, thereby limiting the second drill rod 4 and preventing the second drill rod 4 from deviating.

[0053] The operator then starts the reaming motor 622 to drive the turntable 621 to rotate, thereby driving the three reaming cutters 61 to slide in a direction away from the axis of the drill bit 31, so that the reaming cutters 61 extend out of the slide slot 311, and then starts the drive motor 52 to drive the drill bit 31 to rotate. The rotation of the drill bit 31 drives the reaming cutter 61 to rotate, and the drill hole is expanded, and the inclined drill hole is expanded into a straight hole with a larger aperture. The operator then rotates the reaming motor 622 in the opposite direction to rotate the turntable 621 in the opposite direction, thereby causing the three reaming cutters 61 to slide in a direction close to the axis of the drill bit 31, and the reaming cutters 61 are retracted into the slide slot 311. After the inclinometer has measured correctly, the drive motor 52 and the first hydraulic telescopic rod 51 can be restarted to continue drilling.

[0054] Based on the detected drilling deviation angle, the maximum offset distance of the drilling can be calculated, thereby obtaining the size of the reaming knife 61 that needs to extend out of the slide slot 311. By controlling the number of circles that the motor drives the turntable 621 to rotate, the size of the reaming knife 61 extending out of the slide slot 311 can be controlled.

[0055] The implementation principle of a drilling deviation correction device in the embodiment of the present application is:

[0056] When conducting geological drilling, the operator first uses the rod changing device to move the second drill rod 4 to the bottom of the mounting block 2, and uses the second hydraulic telescopic rod 63 to drive the limiting arc plate 64 to clamp and fix the bottom of the second drill rod 4. Under the action of the positioning arc plate, the second drill rod 4 is coaxial with the rotating block 22, and then the operator starts the rod changing motor 21, which drives the rotating block 22 to rotate, and at the same time, the first hydraulic telescopic rod 51 drives the mounting block 2 to move downward until the rotating block 22 and the second drill rod 4 are fixed through the external thread on the rotating block 22 and the internal thread in the second mounting groove 42. Then the operator controls the second hydraulic telescopic rod 63 to retract, so that the positioning arc plate is away from the second drill rod 4.

[0057] The operator then drives the first hydraulic telescopic rod 51 to extend, thereby driving the first drill rod 3 to move upward, and then moves the first drill rod 3 to the bottom of the second drill rod 4, and uses the second hydraulic telescopic rod 63 to drive the limiting arc plate 64 to clamp and fix the top of the first drill rod 3. Under the action of the positioning arc plate, the first drill rod 3 and the second drill rod 4 are coaxial, and then the operator starts the rod changing motor 21, and the rod changing motor 21 drives the rotating block 22 to rotate. At the same time, the first hydraulic telescopic rod 51 drives the mounting block 2 to move downward until the joint 41 on the second drill rod 4 is fixed to the first drill rod 3 through the external thread on the joint 41 and the internal thread in the first mounting groove 32, completing the installation of the first drill rod 3 and the second drill rod 4. Then the operator controls the second hydraulic telescopic rod 63 to retract, so that the positioning arc plate is away from the first drill rod 3.

[0058] After the first drill rod 3 and the second drill rod 4 are installed, the operator starts the drive motor 52 and the first hydraulic telescopic rod 51. The drive motor 52 drives the drill bit 31 to rotate, and the first hydraulic telescopic rod 51 drives the slider 72 and the mounting block 2 to slide downward along the guide rod 71, thereby driving the first drill rod 3, the second drill rod 4 and the drill bit 31 to feed downward.

[0059] When the top of the second drill rod 4 is about to be fed into the ground, the rod-changing motor 21 is reversed to drive the rotating block 22 to rotate in the opposite direction. At the same time, the first hydraulic telescopic rod 51 drives the slider 72 and the mounting block 2 to move upward, so that the rotating block 22 is separated from the second drill rod 4. Then, the first hydraulic telescopic rod 51 is used to drive the slider 72 and the mounting block 2 to move upward and reset. When the slider 72 and the mounting block 2 move to the initial position, the operator uses the rod-changing equipment to move another second drill rod 4 to the bottom of the mounting block 2, repeats the installation process of the second drill rod 4, and fixes the two ends of the latter second drill rod 4 to the rotating block 22 and the previous second drill rod 4 respectively. At this time, the operator can start the drive motor 52 and the first hydraulic telescopic rod 51 to continue to feed the drilling downward.

[0060] During geological drilling, when the operator detects that the drilling hole has deviated, the operator first drives the first hydraulic telescopic rod 51 to extend, thereby driving the first drill rod 3, the second drill rod 4 and the drill bit 31 to be lifted upward to the position where the drilling hole was last measured, and then uses the second hydraulic telescopic rod 63 to drive the limiting arc plate 64 to slide in the direction close to the second drill rod 4 until the limiting slide plate abuts against the second drill rod 4, thereby limiting the second drill rod 4 and preventing the second drill rod 4 from deviating.

[0061] The operator then starts the reaming motor 622 to drive the turntable 621 to rotate, thereby driving the three reaming cutters 61 to slide in a direction away from the axis of the drill bit 31, so that the reaming cutters 61 extend out of the slide slot 311, and then starts the drive motor 52 to drive the drill bit 31 to rotate. The rotation of the drill bit 31 drives the reaming cutter 61 to rotate, and the drill hole is expanded, and the inclined drill hole is expanded into a straight hole with a larger aperture. The operator then rotates the reaming motor 622 in the opposite direction to rotate the turntable 621 in the opposite direction, thereby causing the three reaming cutters 61 to slide in a direction close to the axis of the drill bit 31, and the reaming cutters 61 are retracted into the slide slot 311. After the inclinometer has measured correctly, the drive motor 52 and the first hydraulic telescopic rod 51 can be restarted to continue drilling.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
