Description

Technical Field

[0001] This utility model relates to the field of hole measurement equipment technology, and specifically to a drilling test device. Background Technology

[0002] Currently, drilling operations in underground engineering processes such as blasting excavation, grouting reinforcement, and anchor bolt support are still mainly carried out manually or by manually operated machinery. During the drilling process, it is difficult to accurately control the orientation and inclination of the borehole. After the drilling is completed, the orientation and inclination of the borehole need to be checked and verified.

[0003] For example, patent CN219511441U discloses a borehole measuring instrument, which includes: a multi-segment telescopic rod, a measuring rod, and a protractor. The multi-segment telescopic rod and the measuring rod are connected collinearly. It also includes a movable rod and a gravity ball. The movable rod is sleeved on the measuring rod and can move flexibly on it. The movable rod and the measuring rod are perpendicular to each other and are detachably connected. The protractor is fixedly connected to the movable rod, with its arc surface facing downwards and its horizontal plane perpendicular to the movable rod. The gravity ball is hinged to the protractor. This device, through the combination of the multi-segment telescopic rod, the measuring rod, the movable rod, the protractor, the gravity ball, and the spring-loaded movable block, achieves the measurement of borehole depth and borehole inclination angle.

[0004] However, current on-site verification tests of borehole azimuth and inclination require the use of tools such as compasses or angle gauges. During measurement, a gravity ball must be fixed to the measuring rod, and the inclination angle is read visually. This measurement method is susceptible to human error, mechanical friction, and vibration, resulting in low efficiency and measurement accuracy. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a drilling test device to solve the technical problems of low efficiency and low measurement accuracy in the existing methods of measuring drilling orientation and inclination, which are easily affected by human reading errors, mechanical friction and vibration.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a drilling test device, including: a positioning component, a horizontal measuring component, and an attitude sensor. The positioning component has a positioning end with an outer diameter that matches the inner diameter of the hole to be tested. The positioning end is used to insert into the hole to position it. The horizontal measuring component is connected to the positioning component and has a horizontal measuring end perpendicular to the axis of the positioning end for measuring the lateral levelness of the positioning end. The attitude sensor is connected to the positioning component, and the reference axis measured by the attitude sensor is parallel to or coincides with the axis of the positioning end.

[0007] In some embodiments, the positioning element includes a rigid fixing part and a flexible positioning part. The rigid fixing part is connected to the horizontal measuring element and the attitude sensor, and its axis is parallel or coincident with the reference axis of the attitude sensor and perpendicular to the horizontal measuring end. The flexible positioning part is sleeved on the rigid fixing part, and its outer diameter matches the inner diameter of the hole to be measured, and it can generate relative deformation when in contact with the hole wall.

[0008] In some embodiments, the flexible positioning part includes a fixed rubber sleeve and a plurality of annular wing plates. The fixed rubber sleeve is sleeved and connected to the rigid fixing part. The plurality of annular wing plates are spaced apart along the axial direction of the fixed rubber sleeve and are connected to the outer wall of the fixed rubber sleeve.

[0009] In some embodiments, two flexible positioning parts are provided, and the two flexible positioning parts are respectively disposed at both ends of the rigid fixing part.

[0010] In some embodiments, the drilling test apparatus further includes a rotating gimbal, wherein the horizontal measuring element and the conveying attitude sensor are rotatably connected to the positioning element via the conveying rotating gimbal.

[0011] In some embodiments, the rotating gimbal includes an upper plate, a lower plate, and a locking knob. The upper plate is connected to the horizontal measuring element and the attitude sensor. The lower plate is connected to the positioning element, and one end of the lower plate extends into the upper plate and is rotatably connected to the upper plate. The locking knob is located on one side of the upper plate, and one end of the lower plate is threadedly connected to the upper plate and abuts against the lower plate.

[0012] In some embodiments, the rotating gimbal further includes a first fixing screw, one end of which is fixedly connected to the lower plate, and the other end of which is threadedly connected to a first threaded hole provided at one end of the positioning member.

[0013] In some embodiments, the drilling test apparatus further includes a mounting platform and a touch display screen. The mounting platform is connected to the upper plate and has a mounting surface perpendicular to the axis of the positioning end. The touch display screen and the horizontal measuring element are both mounted on the mounting surface.

[0015] In some embodiments, the level measuring element is a bubble level.

[0016] Compared with existing technologies, the drilling testing device provided by this utility model, through the setting of a positioning component, a horizontal measuring component, and an attitude sensor, allows the positioning component's outer diameter to match the inner diameter of the hole to be tested, enabling it to be stably inserted into the hole to locate its position. The horizontal measuring component can measure the lateral levelness of the positioning end in real time, ensuring the accuracy of the borehole inclination measurement benchmark. Simultaneously, the device uses a low-power, high-precision attitude sensor as the measuring unit, which can directly measure the inclination angle of the positioning end axis, quickly and accurately acquiring the borehole's azimuth and inclination data. This achieves precise positioning of the hole and accurate measurement of its inclination angle. The entire measurement process is simple to operate, highly efficient, and provides accurate and reliable data. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problems of low efficiency and low accuracy in measuring borehole orientation and inclination angle, which are easily affected by human reading errors, mechanical friction, and vibration, this utility model provides a borehole testing device that achieves precise positioning of the borehole and accurate measurement of its inclination angle. The measurement process is simple to operate, highly efficient, and provides accurate and reliable data.

[0021] Please see Figure 1 and Figure 2The drilling test device includes: a positioning component 1, a horizontal measuring component 2, and an attitude sensor 3. The positioning component 1 has a positioning end whose outer diameter is configured to match the inner diameter of the hole to be tested. The positioning end is used to insert into the hole to be tested to position the hole. The horizontal measuring component 2 is connected to the positioning component 1 and has a horizontal measuring end perpendicular to the axis of the positioning end, used to measure the lateral levelness of the positioning end. The attitude sensor 3 is connected to the positioning component 1, and the reference axis measured by the attitude sensor 3 is parallel to or coincides with the axis of the positioning end.

[0022] In this device, the outer diameter of the positioning end of the positioning component 1 matches the inner diameter of the hole to be measured, allowing it to be stably inserted into the hole to position it. The horizontal measuring component 2 can measure the lateral levelness of the positioning end in real time, providing a static reference. By leveling the horizontal measuring component 2, the coordinate system of the positioning component 1 can be aligned with the direction of gravity, thereby eliminating measurement errors caused by tilting and ensuring the accuracy of the borehole inclination measurement reference. The reference axis measured by the attitude sensor 3 is parallel or coincident with the axis of the positioning end, so that the pitch angle and yaw angle measured by it are the borehole inclination and dip angle, thus enabling the rapid and accurate acquisition of borehole azimuth and inclination data. This device is suitable for measuring the azimuth and inclination of boreholes used in blasting, grouting, and anchor bolt support.

[0023] It should be noted that the attitude sensor 3 includes motion sensors such as a three-axis gyroscope, a three-axis accelerometer, and a three-axis electronic compass. Utilizing a quaternion-based three-dimensional algorithm and advanced data fusion technology, it can provide drift-free three-dimensional attitude and orientation information in real time, expressed in quaternions and Euler angles. By using the attitude sensor 3, the orientation and inclination data of the borehole can be acquired quickly and accurately. Furthermore, this device can be used not only for measuring boreholes in the vertical direction but also for measuring boreholes in the horizontal direction. When measuring boreholes in the horizontal direction, the positioning end of the positioning component 1 is inserted into the hole to be measured. Then, the horizontal measuring component 2 is adjusted to a horizontal state, and the orientation and inclination data of the borehole are measured using the attitude sensor 3.

[0024] In this embodiment, the positioning component 1 consists of two parts: a rigid fixing part 11 and a flexible positioning part 12. The rigid fixing part 11 is connected to the horizontal measuring component 2 and the attitude sensor 3. Its axis is parallel or coincident with the reference axis of the attitude sensor 3 and perpendicular to the horizontal measuring end. The flexible positioning part 12 is sleeved on the rigid fixing part 11. Its outer diameter matches the inner diameter of the hole to be measured and it can generate relative deformation when it contacts the hole wall.

[0025] The flexible positioning part 12 enhances the adaptability of the device, allowing it to maintain a tight fit with the hole wall even when the hole size is non-standard or the hole wall has slight deformation. Simultaneously, during measurement, the deformation generated by the contact between the flexible positioning part 12 and the hole wall provides additional friction, preventing the device from sliding or rotating within the hole, thus ensuring the reliability of the measurement results. The rigid fixing part 11 provides stable support for the flexible positioning part 12; this combination of rigidity and flexibility ensures both the stability of the device and enhances its adaptability to different holes. Of course, in other possible embodiments, the positioning element 1 can also be a rigid guide rod with an outer diameter matching the inner diameter of the hole to be measured, allowing it to be directly inserted into the hole for positioning.

[0026] In one embodiment, the rigid fixing part 11 includes a guide rod 111, the bottom of which is designed to be hemispherical so as to extend into the hole to be measured. The flexible positioning part 12 includes a fixing rubber sleeve 121 and several annular wing plates 122. The fixing rubber sleeve 121 is detachable and is sleeved and connected to the rigid fixing part 11. When measuring holes of different sizes, flexible positioning parts 12 with different outer diameters can be replaced to adapt to holes with different inner diameters. Several annular wing plates 122 form positioning ends, which are evenly and spaced along the axial direction of the fixing rubber sleeve 121 on the outer side wall of the fixing rubber sleeve 121. The outer diameter of the annular wing plate 122 matches the inner diameter of the hole to be measured, and the axis of its outer diameter coincides with the central axis of the guide rod 111. The annular wing plate 122 has a certain elasticity, so that the annular wing plate 122 can generate relative deformation when it contacts the hole wall, thereby tightly fitting the hole wall to accurately locate the orientation of the hole to be measured.

[0027] Furthermore, in some possible embodiments, two flexible positioning parts 12 are provided, with each flexible positioning part 12 respectively disposed at both ends of the rigid fixing part. When the device is inserted into the hole to be measured, the flexible positioning parts 12 at both ends can simultaneously contact the hole wall, forming dual positioning, effectively preventing the device from shifting within the hole, and further improving the accuracy of hole measurement.

[0028] It should be noted that in other possible embodiments, the rigid fixing part 11 and the flexible positioning part 12 may also adopt other structural forms. For example, the rigid fixing part 11 may adopt an adjustable-length telescopic rod design to adapt to the test hole of different depths. The flexible positioning part 12 may adopt a cylindrical structure made of rubber, which is sleeved on the outside of the rigid fixing part 11 and can contact the hole wall to position the test hole.

[0029] In some embodiments, the drilling test apparatus further includes a rotating gimbal 4, and the horizontal measuring element 2 and the attitude sensor 3 are rotatably connected to the positioning element 1 via the rotating gimbal 4. The design of the rotating gimbal 4 allows for 360-degree rotation of the attitude sensor 3 and the horizontal measuring element 2 in the horizontal plane, facilitating measurement of different orientations of the hole under test and enabling omnidirectional, multi-angle measurement of the hole.

[0030] In one embodiment, the rotating gimbal 4 includes an upper plate 41, a lower plate 42, and a locking knob 43. The upper plate 41 is connected to the horizontal measuring element 2 and the attitude sensor 3. The lower plate 42 is connected to the positioning element 1, and one end of the lower plate 42 extends into the upper plate 41 and is rotatably connected to the upper plate 41, allowing the horizontal measuring element 2 and the attitude sensor 3 to rotate relative to the positioning element 1. The locking knob 43 is located on one side of the upper plate 41, and one end of the lower plate 42 is threaded to the upper plate 41 and abuts against the portion of the lower plate 42 that extends into the upper plate 41. It is used to lock the relative position between the upper plate 41 and the lower plate 42, thereby fixing the rotation angle of the horizontal measuring element 2 and the attitude sensor 3.

[0031] Furthermore, in some possible embodiments, the device also includes a mounting platform 5 and a touch display screen 6. The upper plate 41 is connected to the horizontal measuring element 2 and the attitude sensor 3 via the mounting platform 5. The mounting platform 5 is connected to the upper plate 41 and is L-shaped. It has a vertical axis and a horizontal axis that are connected to each other. A groove is provided on one side of the vertical axis, through which the attitude sensor 3 is mounted. The outer side of the horizontal axis has a mounting surface perpendicular to the axis of the positioning end. The touch display screen 6 and the horizontal measuring element 2 are both mounted on the mounting surface.

[0032] Furthermore, in some possible embodiments, the interior of the horizontal axis of the mounting platform 5 is a hollow structure, housing an electronic motherboard 7, a rechargeable battery 8, and a charging interface 9. One end of the charging interface 9 is located on the side wall of the horizontal axis for easy connection to an external power source, providing power to the electronic motherboard 7 and the rechargeable battery 8. The electronic motherboard 7 is electrically connected to the touch display screen 6 and the attitude sensor 3, and is used to receive and process the data measured by the attitude sensor 3, displaying the processing results on the touch display screen 6.

[0033] In some possible embodiments, the rotating gimbal 4 further includes a first fixing screw 44 and a second fixing rod. One end of the first fixing screw 44 is fixedly connected to the lower plate 42, and the other end of the first fixing screw 44 is threadedly connected to a first threaded hole provided at one end of the positioning member 1. One end of the second fixing screw 45 is fixedly connected to the upper plate 41, and the other end of the second fixing screw 45 is threadedly connected to a second threaded hole opened at the bottom of the mounting platform 5. The design of the first fixing screw 44 and the second fixing screw 45 facilitates the disassembly and assembly of the rotating gimbal 4, the positioning member 1, and the mounting platform 5, and facilitates subsequent maintenance and replacement of components.

[0034] Preferably, in this embodiment, the level measuring component 2 is a bubble level 21. The core component of the bubble level 21 is a bubble tube, which is perpendicular to the guide rod 111 and is filled with liquid with air bubbles. The bubbles can move freely within the liquid cavity, and when the bubbles are centered, it indicates that the measuring surface is parallel to the horizontal plane. The bubble tube is also provided with scale lines, which are engraved on the outer surface of the liquid cavity or on the transparent protective layer covering it, to indicate the position of the bubbles relative to the liquid cavity, so that the levelness can be read intuitively.

[0035] Of course, in other possible embodiments, the level measuring element 2 may also adopt other types of level measuring structures, such as electronic levels, etc.

[0036] To better understand this utility model, the following is combined with... Figure 1 and Figure 2 The technical solution of this utility model is described in detail, including the following steps: (1) Select a positioning element 1 that matches the test aperture and install it on the guide rod 111.

[0037] (2) Insert the guide rod 111 into the borehole to be tested.

[0038] (3) Rotate the rotating gimbal 4 until the bubble level 21 is in a horizontal state, so that the longitudinal axis of the attitude sensor 3 is aligned with the borehole axis.

[0039] (4) Operate the touch screen 6, read the yaw angle measured by the sensor, which is the drilling tendency, and read the pitch angle measured by the sensor, which is the drilling inclination angle.

[0040] This invention utilizes a positioning component 1, a horizontal measuring component 2, and an attitude sensor 3. The outer diameter of the positioning end of the positioning component 1 matches the inner diameter of the hole to be measured, allowing it to be securely inserted into the hole for positioning. The horizontal measuring component 2 measures the lateral levelness of the positioning end in real time, ensuring accurate measurement of the borehole's inclination angle. Simultaneously, the device employs a low-power, high-precision attitude sensor 3 as the measuring unit, which can directly measure the tilt angle of the positioning end axis. This allows for rapid and accurate acquisition of the borehole's azimuth and inclination angle data, achieving precise positioning of the hole and accurate measurement of its tilt angle. The entire measurement process is simple to operate, highly efficient, and provides accurate and reliable data.
