Description

Technical Field

[0001] This application relates to the field of drilling equipment, and in particular to a drilling rig positioning and adjustment device. Background Technology

[0002] Drilling rigs are mechanical devices used in exploration or mineral resource development to drive drilling tools into the ground to obtain physical geological data. In the construction industry, drilling rigs are also commonly used to drill pile holes in order to complete the laying of pile foundations.

[0003] When drilling pile holes, the spatial position of the drilling rig needs to be adjusted first to ensure that the drill bit is perpendicular to the horizontal plane, thereby ensuring the verticality of the pile hole. However, when the drilling rig drives the drill bit to drill, the drilling rig will generate vibration during operation. As the drilling time increases, the foundation will be affected by the vibration of the drilling rig, resulting in depression and causing the drill bit to tilt. This will reduce the verticality of the pile hole and affect the quality of drilling. Summary of the Invention

[0004] To address the issue of drilling rig vibration causing ground subsidence, drill bit tilting, and consequently reduced pile hole verticality, thus affecting pile hole quality, this application provides a drilling rig positioning adjustment device.

[0005] The drilling rig positioning and adjustment device provided in this application adopts the following technical solution: A drilling rig positioning and adjustment device includes a drilling frame with multiple support legs placed on a foundation. A sliding plate is slidably mounted on the drilling frame, and the sliding plate has an adjustment hole. An adjustment block for inserting into the adjustment hole is mounted on the drilling frame. A drill shaft is mounted on the adjustment block in a vertical direction, and the adjustment block is rotatable in a vertical direction. An adjustment unit for driving the adjustment block to rotate is mounted on the drilling frame. A sliding unit for driving the adjustment hole to slide is also mounted on the drilling frame. The sliding unit and the adjustment unit correspond one-to-one with the support legs. A horizontal monitoring unit is mounted on the foundation, and the horizontal monitoring unit corresponds one-to-one with the adjustment unit. The horizontal monitoring unit is used to drive the adjustment unit to perform adjustment. A positioning unit for limiting the horizontal circumferential rotation of the adjustment block is mounted on the drilling frame.

[0006] By adopting the above technical solution, before drilling the pile hole, the drill frame is first installed on the foundation with multiple support legs, then adjusted to be horizontal, and the drill shaft is in a vertical state. A horizontal monitoring unit is installed at the corresponding foundation position of each support leg. Then, the pile hole is drilled. The adjusting block rotates relative to the drill rod under the pull of the positioning unit. As drilling progresses, the horizontal monitoring unit detects a depression at the corresponding support leg position. At this time, the horizontal monitoring unit controls the adjusting unit at the corresponding position of the support leg to push the adjusting block to rotate in the adjusting hole, so that the drill shaft is in a vertical position. At the same time, the sliding unit drives the sliding plate to slide, so that the drill shaft returns to the initial position, thereby reducing the impact of foundation depression on the verticality of the pile hole, improving the verticality of the drilling rig during drilling, and improving the drilling quality.

[0007] In one specific implementation, the sliding unit includes a first adjusting screw, a second adjusting screw, and a support plate. The first adjusting screw is rotatably mounted on the drill frame, and the support plate is mounted on the first adjusting screw. The first adjusting screw can drive the support plate to slide. The second adjusting screw is rotatably mounted on the support plate, and the sliding plate is mounted on the second adjusting screw. The second adjusting screw can drive the sliding plate to slide. The axes of the first adjusting screw and the second adjusting screw are out of plane.

[0008] By adopting the above technical solution, when the drilling frame tilts due to foundation settlement, the first adjusting screw is rotated, which drives the support plate to slide. Then, the second adjusting screw is rotated, which drives the sliding plate to slide, thereby allowing the rotating shaft to return to its initial position, effectively preventing the drilling shaft from shifting and affecting the verticality of the pile hole.

[0009] In one specific implementation scheme, an adjustment plate is fixedly provided on the adjustment block; The adjustment unit includes a hydraulic cylinder and a connecting member. The cylinder body of the hydraulic cylinder is fixedly mounted on the sliding plate, and the piston rod of the hydraulic cylinder is connected to the adjustment plate through the connecting member.

[0010] By adopting the above technical solution, when the drill frame deviates, the hydraulic cylinder corresponding to the deviated position extends and retracts, and the hydraulic cylinders at other positions cooperate with the corresponding hydraulic cylinders to enable the hydraulic cylinders to drive the adjusting block to rotate in the adjusting hole, thereby adjusting the tilt angle of the drill shaft so that the drill shaft can be in a vertical state.

[0011] In one specific implementation, the connector includes a connecting plate and a connecting block. The connecting plate is rotatably mounted on the adjusting plate and has a connecting groove. The piston rod of the hydraulic cylinder is ball-jointed with the connecting block. The connecting block is slidably mounted in the connecting groove and is eccentrically positioned with respect to the rotation axis of the connecting plate.

[0012] By adopting the above technical solution, when the hydraulic cylinder adjusts the drill shaft, the hydraulic cylinder and the adjusting plate are tilted. The hydraulic cylinder extends and pushes the connecting block to slide in the connecting groove. At the same time, the connecting plate rotates around its own axis. As the hydraulic cylinder extends, the adjusting plate is horizontal, thereby making the drill shaft vertical and realizing the adjustment of the drill shaft's verticality.

[0013] In one specific implementation, the horizontal monitoring unit includes a laser generator, a laser receiver, and a controller. The laser generator is mounted on the adjustment plate, and a support rod is provided on the foundation. There are three sets of laser receivers, which are spaced apart along the length of the support rod. The laser generator faces the laser receivers. The laser receivers are electrically connected to the controller, which is used to control the extension or retraction of the hydraulic cylinder.

[0014] By adopting the above technical solution, before drilling, the support rod is first installed in the corresponding position on the support leg. Then, the adjustment plate is adjusted so that each laser generator is aligned with the laser receiver in the middle position. As drilling proceeds, the foundation sinks, causing the support leg in the corresponding position to fall. This causes the laser emitted by the laser generator in the corresponding position of the adjustment plate to deviate upward or downward from the laser receiver in the middle position. Then, the laser receiver controls the extension and retraction of the hydraulic cylinder in the corresponding sinking position through the controller to adjust the tilt angle of the drill shaft. At the same time, the laser receiver controls the rotation of the first adjustment screw and the second adjustment screw through the controller, so that the drill shaft returns to the initial position.

[0015] In one specific implementation, an adjusting screw is rotatably mounted on the support rod, the adjusting screw being arranged along the length of the support rod. The adjusting screw includes a first adjusting section and a second adjusting section, the threads of the first adjusting section and the second adjusting section having opposite directions. A first slider and a second slider are slidably mounted on the support rod, the first adjusting section passing through the first slider and being threadedly connected, the second adjusting section passing through the second slider and being threadedly connected, one set of laser receivers being mounted on the first slider, another set of laser receivers being mounted on the second slider, and the remaining set of laser receivers being mounted between the first slider and the second slider.

[0016] By adopting the above technical solution, when adjusting the adjustment distance of the laser sensor, by rotating the adjustment screw, the adjustment screw drives the first slider and the second slider to move away from or closer to each other through the first adjustment section and the second adjustment section. The first slider and the second slider drive the two laser receivers to move away from or closer to each other. By adjusting the distance between the middle laser receiver and the two side laser receivers, the sensitivity of the drill shaft offset can be adjusted, improving the convenience of using the adjustment device.

[0017] In one specific implementation, the support rod is provided with an adjusting rod, which is inserted into the support rod and threadedly connected to the support rod, and the adjusting rod is provided with a tip.

[0018] By adopting the above technical solution, the installation height of the laser receiver on the support rod can be adjusted by rotating the adjustment rod, thereby facilitating the adjustment of the horizontal position of the laser receiver and the laser generator.

[0019] In one specific implementation, the adjusting block is provided with a support cylinder, and the drill shaft passes through the support cylinder and is rotatably configured with the support cylinder; The positioning unit includes multiple limiting rods and support rods, with each limiting rod corresponding to one of the support rods. Each limiting rod has a limiting groove and a limiting block for sliding within the limiting groove. One end of each support rod is ball-hinged with the support cylinder, and the other end of each support rod is ball-hinged with the limiting block.

[0020] By adopting the above technical solution, when the drill frame tilts, the adjusting block causes the support cylinder and the limiting rod to tilt. The support cylinder drives the limiting block to slide in the limiting groove through the support rod, thereby adapting to the tilt between the drill shaft and the drill frame. At the same time, the limiting block restricts the support rod, thereby limiting the horizontal rotation of the support cylinder and improving the stability of the drill shaft rotation.

[0021] In one specific implementation, the adjustment plate is equipped with a drive motor, and the output shaft of the drive motor is coaxially fixed with the drill shaft.

[0022] By adopting the above technical solution, the drill shaft is driven to rotate by the drive motor, and the tilt and position of the drill shaft connected to the drive motor can be adjusted by the adjustment plate, thereby improving the convenience of drill shaft adjustment.

[0023] In one specific implementation, the drill frame is equipped with a counterweight.

[0024] By adopting the above technical solution, the counterweight can make the connection between the drill frame and the foundation more secure, thereby improving the stability of the drill shaft rotation.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When the vibration of the drill shaft causes the drill frame to tilt, the horizontal monitoring unit detects a depression at the corresponding support leg position. At this time, the horizontal monitoring unit controls the adjustment unit at the corresponding position of the support leg to push the adjustment block to rotate in the adjustment hole, so that the drill shaft is in a vertical position. At the same time, the sliding unit drives the sliding plate to slide, so that the drill shaft returns to the initial position. This allows for timely adjustment of the tilted drill shaft, reducing the impact of foundation depression on the verticality of the pile hole and improving the verticality of the drilling rig during drilling. 2. By adjusting the distance between the middle laser receiver and the laser receivers on both sides, the angle of the drill shaft offset can be adjusted, and the controller controls the extension and retraction of the hydraulic cylinder to adjust the drill shaft, thereby enabling the adjustment of the sensitivity of the positioning adjustment device and improving the applicability of the adjustment device.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a drilling rig positioning and adjustment device.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A drilling rig positioning and adjustment device includes a drill frame 1, on which multiple support legs 11 are placed on the foundation. In this embodiment, there are four support legs 11, which are evenly arranged along the circumference of the tangent circle. The drill frame 1 is provided with a sliding unit 2, on which a sliding plate 21 is slidably mounted. The sliding plate 21 is provided with an adjustment hole 211, which is a circular hole with an arc-shaped cross-section of the hole wall. The drill frame 1 is provided with an adjustment block 22 for inserting into the adjustment hole 211. The adjustment block 22 is slidably connected to the adjustment hole 211 and has a concave-convex fit. A drill shaft 3 is provided on the adjustment block 22 along the vertical direction, and the drill shaft 3 passes through the adjustment block 22. The adjustment block 22 is rotatably set together with the adjustment block 22. The axis of the drill shaft 3 is collinear with the axis of the adjustment block 22. The adjustment block 22 can rotate in the vertical direction. The sliding plate 21 is provided with an adjustment unit 4 for driving the adjustment block 22 to rotate. There are four adjustment units 4. Each adjustment unit 4 corresponds to a support leg 11. A horizontal monitoring unit 5 is provided on the foundation. The horizontal monitoring unit 5 corresponds to the adjustment unit 4. The horizontal monitoring unit 5 is used to drive the adjustment unit 4 and the sliding unit 2. The drill frame 1 is provided with a positioning unit 6 for limiting the horizontal circumferential rotation of the adjustment block 22. The drill frame 1 is provided with two counterweights 12. The two counterweights 12 are symmetrically distributed on both sides of the drill shaft 3.

[0034] When installing the drill frame 1, first install the drill frame 1 in the designated position, then install the horizontal monitoring unit 5 on the foundation corresponding to each support leg 11. Then, adjust the position of the drill shaft 3 using the adjusting unit 4 and the sliding unit 2, and monitor the horizontal position using the horizontal monitoring unit 5 to ensure the drill shaft 3 is vertical. The positioning unit 6 restricts the circumferential movement of the adjusting block 22, causing the drill shaft 3 to rotate. The drill shaft 3 drives the drill rod and drill bit to drill. As drilling progresses, the positions of the four support legs 11 will show varying degrees of indentation. This causes the drill frame 1 to tilt towards the support leg 11 where the depression is deepest. At this time, the horizontal monitoring unit 5 detects the tilt of the drill frame 1 and drives the adjustment unit 4 corresponding to the position of the support leg 11 to adjust the deflection angle of the adjustment block 22. At the same time, the horizontal monitoring unit 5 also drives the sliding unit 2 to move the sliding plate 21 to the initial position. The adjustment unit 4 adjusts the drill shaft 3 to a vertical state, thereby realizing timely adjustment of the tilt of the drill shaft 3 during the drilling process, reducing the impact of the foundation depression on the verticality of the pile hole, and improving the verticality of the drilling rig.

[0035] Reference Figure 1 , Figure 3The sliding unit 2 includes a first adjusting screw 23, a second adjusting screw 24, and a support plate 25. The axis of the first adjusting screw 23 is parallel to the line connecting two oppositely arranged support legs 11, and the axis of the second adjusting screw 24 is parallel to the line connecting the other two oppositely arranged support legs 11, thus making the axis of the first adjusting screw 23 and the axis of the second adjusting screw 24 perpendicular to each other. There are two first adjusting screws 23, and both first adjusting screws 23 are inserted into the drill frame 1 and rotatably mounted with the drill frame 1. The support plate 25 is provided with a rotary motor 26 for driving the first adjusting screw 23 to rotate. The support plate 25 is provided on the two first adjusting screws 23. Each first adjusting screw 23 passes through the support plate 25 and is threadedly connected to the support plate 25. The second adjusting screw 24 is rotatably provided on the support plate 25. The sliding plate 21 is slidably provided on the support plate 25. The second adjusting screw 24 passes through the sliding plate 21 and is threadedly connected to the sliding plate 21. The support plate 25 is also provided with a rotary motor 26 for driving the second adjusting screw 24 to rotate.

[0036] Reference Figure 2 A support cylinder 221 is fixedly mounted on the adjusting block 22. The drill shaft 3 passes through the support cylinder 221 and is rotatably mounted on the support cylinder 221. An adjusting plate 222 is fixedly mounted on the support cylinder 221 and is perpendicular to the support cylinder 221. The adjusting unit 4 includes a hydraulic cylinder 41 and a connecting member 42. The cylinder body of the hydraulic cylinder 41 is fixedly mounted on the sliding plate 21. The connecting member 42 includes a connecting plate 421 and a connecting block 422. The connecting plate 421 is rotatably mounted on the bottom wall of the adjusting plate 222 via a rotating shaft. The connecting plate 421 is provided with a connecting groove 423, which is set along the length of the connecting plate 421. The connecting groove 423 is a dovetail groove. The connecting block 422 is slidably mounted in the connecting groove 423. The connecting block 422 and the connecting groove 423 are in a concave-convex fit. The piston rod of the hydraulic cylinder 41 is ball-jointed with the connecting block 422. The connecting groove 423 is located on one side of the rotation axis of the connecting block 422.

[0037] Reference Figure 2 , Figure 3 and Figure 4A drive motor 7 is fixedly mounted on the adjusting plate 222. The output shaft of the drive motor 7 is connected to the drill shaft 3 via a coupling. The support cylinder 221 extends downward toward the sliding plate 21. The positioning unit 6 includes multiple limiting rods 61 and support rods 62. In this embodiment, there are four limiting rods 61 and four support rods 62. Each limiting rod 61 is fixedly mounted on the bottom wall of the adjusting plate 222 and extends toward the foundation. Each limiting rod 61 corresponds to the installation position of the support leg 11, so that the support cylinder 221 is surrounded by the four limiting rods 61. Corresponding to each support rod 62, each limiting rod 61 is provided with a limiting groove 63. The limiting groove 63 is set along the length direction of the limiting rod 61 and is a dovetail groove. Each limiting rod 61 is provided with a limiting block 64 for sliding in the limiting groove 63. The limiting block 64 and the limiting groove 63 are in concave-convex fit. The support rod 62 is located between the support cylinder 221 and the limiting rod 61. One end of the support rod 62 is ball-jointed with the support cylinder 221, and the other end of the support rod 62 is ball-jointed with the limiting block 64. The length of the support rod 62 is greater than the distance between the limiting block 64 and the support cylinder 221.

[0038] When the drill frame 1 tilts, the hydraulic cylinder 41 corresponding to the support leg 11 in the tilting direction extends. The remaining hydraulic cylinders 41 also extend to cooperate with the hydraulic cylinders 41 in adjusting the adjusting plate 222. Then, the hydraulic cylinders 41 lift the adjusting plate 222 from the downward tilt position upward. At this time, the hydraulic cylinders 41 drive the connecting block 422 to slide in the connecting groove 423. The connecting plate 421 rotates around the rotating shaft to cooperate with the extension of the hydraulic cylinders 41 to lift the adjusting plate 222. While the adjusting plate 222 is lifted, the two drive motors 7 drive the first adjusting screw 23 and the second adjusting screw 24 to rotate respectively. The first adjusting screw 23 drives the support plate 25 to slide, and the second adjusting screw 24 drives the sliding plate 21 to slide, thereby moving the drill shaft 3 to the initial position, thereby realizing the adjustment of the drill shaft 3 and enabling the drill shaft 3 to return to the initial position and vertical state.

[0039] When the drill shaft 3 rotates, the adjusting block 22 is connected to the limiting block 64 via the support rod 62 on the support cylinder 221, which restricts the circumferential rotation of the adjusting block 22. This improves the strength of the circumferential fixation of the adjusting plate 222 and enhances the stability of the drill shaft 3 rotation. As the drill frame 1 tilts, the drill shaft 3 causes the support cylinder 221 to tilt relative to the drill frame 1. At this time, the limiting block 64 slides in the limiting groove 63, allowing the limiting block 64 to be in different positions to adapt to the tilt between the support cylinder 221 and the limiting rod 61. This improves the flexibility of the limiting rod 61 and the support rod 62 in restricting the circumferential rotation of the adjusting block 22.

[0040] Reference Figure 1The horizontal monitoring unit 5 includes a laser generator 51, a laser receiver 52, and two controllers 53. The laser receiver 52, hydraulic cylinder 41, and one of the controllers 53 are electrically connected and transmit signals. The rotating motor 26, laser generator 51, and the other controller 53 are electrically connected and transmit signals. The laser generator 51 is a laser rangefinder capable of generating laser light and measuring distance. The laser receiver 52 has a built-in photosensitive element. The laser light source from the laser generator 51 illuminates the photosensitive element of the laser receiver 52, causing the controller 53 to be in a conductive state. The laser generator 51 is mounted on the adjusting plate 222. Four support rods 54 are provided on the foundation, each corresponding to a support leg 11. Each support rod 54 has a rotating adjusting screw 55. The adjusting screw 55 rotates along... The adjusting screw 55, which is set along the length of the support rod 54, includes a first adjusting section 551 and a second adjusting section 552. The threads of the first adjusting section 551 and the second adjusting section 552 have opposite directions. A first slider 553 and a second slider 554 are slidably mounted on the support rod 54. A first connecting section passes through the first slider 553 and is threadedly connected. A second connecting section passes through the second slider 554 and is threadedly connected. There are three sets of laser receivers 52 on each support rod 54. The three sets of laser receivers 52 are spaced apart along the length of the support rod 54. One set of laser receivers 52 is mounted on the first slider 553, another set of laser sensors is mounted on the second slider 554, and the remaining set of laser receivers 52 is fixedly mounted on the support rod 54 and located between the first slider 553 and the second slider 554. The laser generator 51 faces the laser receivers 52.

[0041] Reference Figure 1 Each support rod 54 has an adjusting rod 56 at its bottom. One end of the adjusting rod 56 is inserted into the support rod 54 and threadedly connected to it. The other end of the adjusting rod 56 has a tip for insertion into the foundation.

[0042] When adjusting the position of the drill frame 1, the height of each position of the drill frame 1 is adjusted so that each laser generator 51 is aligned with the laser receiver 52 in the middle position, thereby ensuring that the drill shaft 3 is in a vertical state, and the distance between the laser generator 51 and the corresponding laser receiver 52 is fixed. When the drill frame 1 tilts, the laser generator 51 corresponding to the tilted position deflects vertically, and the distance between the laser generator 51 and the laser receiver 52 changes. When the laser generator 51 is offset to be aligned with the upper and lower laser receivers 52, the laser receiver 52 drives the hydraulic cylinder 41 at the corresponding position to extend and retract through the controller 53 to adjust the tilt of the adjusting plate 222. At the same time, the laser generator 51 drives the rotating motor 26 to adjust the position of the sliding plate 21, so that the drill shaft 3 returns to the initial position. When the drill shaft 3 returns to the initial position, the laser generator 51 is aligned with the corresponding middle laser receiver 52, and the distance is the same as the initial position. The hydraulic cylinder 41 and the rotating motor 26 stop driving, thereby realizing the adjustment of the offset angle of the drill shaft 3, and improving the timeliness of the tilt adjustment of the drill shaft 3.

[0043] By rotating the adjusting screw 55, the distance between the middle laser receiver 52 and the two side laser receivers 52 can be adjusted, and the angle of the drill shaft 3 offset can be adjusted. The controller 53 controls the extension and retraction of the hydraulic cylinder 41 to adjust the drill shaft 3, thereby enabling the adjustment of the sensitivity of the positioning adjustment device and improving the applicability of the adjustment device. By rotating the adjusting rod 56, the installation height of the laser receiver 52 on the support rod 54 can be adjusted, thereby facilitating the horizontal position adjustment of the laser receiver 52 and the laser generator 51.

[0044] The implementation principle of the drilling rig positioning and adjustment device in this application embodiment is as follows: Before drilling the pile hole, the drill frame 1 is first installed on the foundation through multiple support legs 11, and then adjusted to be horizontal, so that the drill shaft 3 is in a vertical state. Support rods 54 are installed at the corresponding foundation positions of each support leg 11. Then, the pile hole is drilled. The adjustment block 22 rotates relative to the drill rod under the pull of the support rod 62 and the limit rod 61. As drilling progresses, the laser generator 51 and the laser receiver 52 in the middle position are shifted to one of the other two laser receivers 52. At this time, the laser receiver 52 controls the adjustment unit 4 at the corresponding position of the support leg 11 through the controller 53 to push the adjustment block 22 to rotate in the adjustment hole 211, so that the drill shaft 3 is in a vertical position. At the same time, the laser generator 51 controls the rotating motor 26 through the controller 53 to drive the sliding plate 21 to slide, so that the drill shaft 3 returns to the initial position, thereby reducing the impact of foundation depression on the verticality of the pile hole and improving the verticality of the drilling rig during drilling.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
