Description

Technical Field

[0001] This application relates to the field of environmental monitoring technology for mine blasting holes, and in particular to a leveling device and leveling equipment. Background Technology

[0002] In mining blasting operations, after the blasting holes are drilled, they are typically measured manually using a measuring tape. This method is cumbersome, inefficient, and labor-intensive, and is easily affected by human error and environmental factors, leading to significant measurement errors. More importantly, manual measurement only obtains the hole depth and cannot accurately detect environmental parameters such as hole diameter variations, hole wall smoothness, and the development of surrounding rock fissures. The lack of these parameters and measurement deviations directly result in a mismatch between the subsequent explosive loading plan and the actual working conditions inside the hole, leading to uneven blasting energy distribution, large dispersion in blast fragment size, high root residue rate, and increased risk of flyrock, ultimately resulting in uncontrollable blasting effects and substandard blasting quality. Therefore, borehole environmental measurement requires the use of borehole environmental monitoring devices.

[0003] In related technologies, a borehole environment detection device includes a measuring device and a detection pendant. The measuring device includes a main reel and a signal line wound on the main reel. The end of the signal line is connected to the detection pendant via a line length acquisition device and a pressure detection sensor. The main reel releases the line, allowing the detection pendant to enter the blast hole under gravity. The main unit of the measuring device can determine the motion state and position information of the detection pendant in the borehole by acquiring the signal change characteristics collected by the pressure detection sensor, and detect the depth of the blast hole and the environmental information inside the hole based on the motion state and position information. The borehole environment detection device can quickly and accurately detect environmental information such as the depth of the borehole, the water depth inside the hole, the smoothness of the borehole sidewalls, and protrusion locations. The attitude and position of the borehole environment detection device are crucial to the accuracy of the detection results. When using a borehole environment detection device, it is usually placed on the ground to detect boreholes. Due to the uneven terrain in mines, the detection device is often tilted during use. In this case, the initial falling direction of the detection plumb bob is no longer aligned with the axis of the blast hole, and it may enter the borehole at an angle. The probability of the plumb bob colliding with the borehole wall during its descent is significantly increased. In addition, when the main sheave releases the signal line, there is a risk of friction between the signal line and the sheave wall, which affects the accuracy of the detection results of pressure sensors and other detection components. Summary of the Invention

[0004] The purpose of this application is to provide a leveling device and equipment, which aims to solve the technical problem that current hole environment detection devices are prone to tilting during use, thus affecting the accuracy of detection results.

[0005] A first aspect of this application provides a leveling device, the leveling device comprising:

[0006] A base and an adjustment assembly, wherein the adjustment assembly is connected to the base;

[0007] A mounting bracket and a level, the mounting bracket being adapted to be connected to a hole environment detection device, the level being mounted on the mounting bracket for detecting the levelness of the mounting bracket, and the mounting bracket being kinetically connected to the adjustment assembly;

[0008] The control module is electrically connected to the level and the adjustment component. The control module can drive the adjustment component to adjust the spatial posture of the mounting frame based on the deflection angle information of the mounting frame fed back by the level, so that the level is parallel to the horizontal plane.

[0009] In the above-mentioned solution, the leveling device provided in this application is connected to the hole environment detection device through the mounting frame. After the device is moved into place, if the mounting frame and the connected hole environment detection device tilt due to uneven terrain, the control module can automatically drive the adjustment component to adjust the spatial posture of the mounting frame based on the deflection angle data fed back by the level instrument, so as to ensure that the mounting frame always maintains a horizontal state, so as to synchronously correct the posture of the hole environment detection device, so that the initial falling direction of the detection pendant is precisely aligned with the axis of the blast hole, establishing a reliable benchmark for subsequent detection operations, thereby significantly improving the accuracy of the detection results of the hole environment detection device.

[0010] Optionally, the adjustment assembly includes a base plate and a boom, a first adjustment arm, and a second adjustment arm disposed on the base plate. The base plate is connected to the base. The mounting frame has corresponding first and second sides in the horizontal direction. The boom is connected to the middle of the first side of the mounting frame. The second side has corresponding first and second ends. The first and second adjustment arms are respectively connected to the first and second ends. The first adjustment arm is configured to adjust the height of the first end, and the second adjustment arm is configured to adjust the height of the second end.

[0011] In the above scheme, the adjustment component forms a three-point force support with the boom, the first adjustment arm, and the second adjustment arm, which conforms to the principle of triangular stability structure. This can effectively distribute the weight of the mounting frame and the hole environment detection device, avoid posture swaying or displacement during the leveling process, and the three-point support can accurately lock the horizontal reference of the mounting frame, ensuring that the mounting frame has no additional torsion or displacement when the adjustment arm is adjusted in height, thus providing a stable structural foundation for the level detection and control module adjustment.

[0012] Optionally, the first adjusting arm includes a first driving member, a first rotating arm, and a first adjusting rod. The first driving member is connected to the base plate, and the first adjusting rod is connected to the first driving member through the first rotating arm.

[0013] The first driving member is used to drive the first rotating arm to rotate. The axis of rotation of the first rotating arm is parallel to the horizontal plane, the first adjusting rod is perpendicular to the horizontal plane, one end of the first adjusting rod is hinged to the first rotating arm, and the other end of the first adjusting rod is hinged to the first end.

[0014] In the above scheme, the first driving component drives the first rotating arm to swing around the horizontal axis. Through the linkage structure, the circular swing of the rotating arm is converted into the vertical linear motion of the first adjusting rod. The precise conversion of this motion form can directly and stably drive the corresponding end of the mounting frame to adjust the height, ensuring the accuracy of the leveling action. Moreover, the first driving component is located on one side of the mounting frame, reducing the space occupied in the vertical direction and making the structure more compact.

[0015] Optionally, the second adjusting arm includes a second driving member, a second rotating arm, and a second adjusting rod. The second driving member is connected to the base plate, and the second adjusting rod is connected to the second driving member through the second rotating arm.

[0016] The second driving member is used to drive the second rotating arm to rotate. The axis of rotation of the second rotating arm is parallel to the horizontal plane, the second adjusting rod is perpendicular to the horizontal plane, one end of the second adjusting rod is hinged to the second rotating arm, and the other end of the second adjusting rod is hinged to the second arm.

[0017] In the above scheme, the second driving component drives the second rotating arm to swing around the horizontal axis. Through the linkage structure, the circular swing of the rotating arm is converted into the vertical linear motion of the second adjusting rod. The precise conversion of this motion form can directly and stably drive the corresponding end of the mounting frame to adjust the height, ensuring the accuracy of the leveling action. Moreover, the second driving component is located on one side of the mounting frame, reducing the space occupied in the vertical direction and making the structure more compact.

[0018] Optionally, the boom is connected to the mounting frame via a boom rod, the top end of the boom rod is hinged to the boom rod, the hinge axis of the boom rod is parallel to the horizontal plane and perpendicular to the rotation axis of the first boom rod, and the bottom end of the boom rod is hinged to the mounting frame.

[0019] In the above scheme, the hinge shaft at the top of the boom is arranged perpendicularly to the first swing arm shaft, forming a cross-shaped hinge degree of freedom. This structure allows the mounting frame to flexibly deflect in both the X and Y axes on the horizontal plane, without restricting the leveling action of the first and second adjusting arms due to the fixed connection of the boom, ensuring that the posture adjustment of the mounting frame is uninterrupted during the leveling process.

[0020] Optionally, the adjustment component includes a fourth driving member, the substrate is connected to the base through the fourth driving member, the fourth driving member is used to drive the substrate to rotate, and the rotation axis of the substrate is perpendicular to the horizontal plane.

[0021] In the above scheme, the fourth driving component drives the substrate to rotate around the vertical axis, which can simultaneously drive the mounting frame and the hole environment detection device to rotate horizontally; even if there is an angular deviation between the initial placement position of the leveling device and the blast hole, there is no need to manually move the whole machine. The orientation can be adjusted directly by the fourth driving component to ensure that the initial falling direction of the detection pendant is precisely aligned with the axis of the blast hole, thereby further eliminating positioning errors.

[0022] Optionally, the adjustment assembly further includes a third driving member, the substrate is connected to the fourth driving member through the third driving member, the fourth driving member is used to drive the third driving member to rotate, the rotation axis of the third driving member is perpendicular to the horizontal plane, the third driving member is used to drive the substrate to rotate, and the rotation axis of the substrate is perpendicular to the horizontal plane.

[0023] In the above scheme, the double-layer vertical rotation structure can realize the superimposed rotational motion of the substrate, breaking through the rotation angle limitation of a single driving component; the fourth driving component can drive the substrate to achieve large-angle rapid rotation, which is used to quickly align the approximate location of the blast hole; the third driving component is responsible for small-angle fine-tuning, controlling the alignment error between the falling direction of the detection pendant and the axis of the blast hole within a very small range; this graded adjustment mode takes into account both rotation angle and alignment efficiency and accuracy, and solves the problem that a single driving component cannot simultaneously meet the requirements of large-range rapid adjustment and high-precision calibration.

[0024] Optionally, the adjustment assembly further includes a rotating plate that extends horizontally. One end of the rotating plate is connected to the fourth driving member, which drives the rotating plate to rotate and is located above the rotating plate. The other end of the rotating plate is connected to the third driving member, which is located below the rotating plate. The output shaft of the third driving member extends vertically and is fixedly connected to the rotating plate. The base plate is fixedly connected to the third driving member.

[0025] In the above scheme, the fourth driving component is located above the rotating plate, and the third driving component is located below the rotating plate, forming a compact structure with upper and lower layers. This design can avoid the problem of excessive vertical height caused by the coaxial arrangement of the two driving components and effectively reduce the overall height of the adjustment component.

[0026] Optionally, the substrate extends in a direction away from the mounting bracket, and the substrate has a mounting cavity; the third driving component includes a third motor, a third reducer, and a third synchronous belt. The third motor is located at the bottom of the substrate at the end away from the mounting bracket, and the output shaft of the third motor extends into the mounting cavity. The output shaft of the third motor is provided with a third driving pulley. The third reducer is located at the top of the substrate at the end near the mounting bracket, and the input shaft of the third reducer extends into the mounting cavity. The input shaft of the third reducer is provided with a third driven pulley. The third synchronous belt is sleeved on the third driving pulley and the third driven pulley. The output shaft of the third reducer is fixedly connected to the rotating plate.

[0027] In the above scheme, the third driving pulley, the third driven pulley, and the third synchronous belt are all integrated into the mounting cavity of the substrate, avoiding the exposure of transmission components. This design can effectively isolate dust, gravel, and other impurities in the mine site, reduce the wear and jamming risk of transmission components, and significantly reduce the external space occupied by the third drive component. The third motor is arranged at the bottom of the substrate away from the mounting frame, and the third reducer is arranged at the top of the substrate near the mounting frame. The two are connected by the synchronous belt in the mounting cavity to transmit power. This staggered layout allows the power transmission path to conform to the extension direction of the substrate, avoids interference between the transmission structure and surrounding components, and makes the overall structure of the adjustment assembly more compact.

[0028] A second aspect of this application provides a leveling device, including a leveling vehicle and the leveling device described above. The leveling vehicle includes a frame and a plurality of wheels mounted on the frame. The base of the leveling device is connected to the bottom of the frame, and the bottom of the wheels extends downward out of the leveling device.

[0029] It should be noted that the technical effects brought about by the second aspect of this application can be referred to the technical effects brought about by the corresponding implementation of the first aspect, and will not be repeated here. Attached Figure Description

[0051] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0052] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0054] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, where the range of similarity is within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0055] In mining blasting operations, after the blasting holes are drilled, they are typically measured manually using a measuring tape. This method is cumbersome, inefficient, and labor-intensive, and is easily affected by human error and environmental factors, leading to significant measurement errors. More importantly, manual measurement only obtains the hole depth and cannot accurately detect environmental parameters such as hole diameter variations, hole wall smoothness, and the development of surrounding rock fissures. The lack of these parameters and measurement deviations directly result in a mismatch between the subsequent explosive loading plan and the actual working conditions inside the hole, leading to uneven blasting energy distribution, large dispersion in blast fragment size, high root residue rate, and increased risk of flyrock, ultimately resulting in uncontrollable blasting effects and substandard blasting quality. Therefore, borehole environmental measurement requires the use of borehole environmental monitoring devices.

[0056] In related technologies, a borehole environment detection device includes a measuring device and a detection pendant. The measuring device includes a main reel and a signal line wound on the main reel. The end of the signal line is connected to the detection pendant via a line length acquisition device and a pressure detection sensor. The main reel releases the line, allowing the detection pendant to enter the blast hole under gravity. The main unit of the measuring device can determine the motion state and position information of the detection pendant in the borehole by acquiring the signal change characteristics collected by the pressure detection sensor, and detect the depth of the blast hole and the environmental information inside the hole based on the motion state and position information. The borehole environment detection device can quickly and accurately detect environmental information such as the depth of the borehole, the water depth inside the hole, the smoothness of the borehole sidewalls, and protrusion locations. The attitude and position of the borehole environment detection device are crucial to the accuracy of the detection results. When using a borehole environment detection device, it is usually placed on the ground to detect boreholes. Due to the uneven terrain in mines, the detection device is often tilted during use. In this case, the initial falling direction of the detection plumb bob is no longer aligned with the axis of the blast hole, and it may enter the borehole at an angle. The probability of the plumb bob colliding with the borehole wall during its descent is significantly increased. In addition, when the main sheave releases the signal line, there is a risk of friction between the signal line and the sheave wall, which affects the accuracy of the detection results of pressure sensors and other detection components.

[0057] In this regard, combined with Figures 1 to 4 As shown in the illustration, this application provides a leveling device 1, which includes a base, an adjusting component 10, a mounting frame 20, a level, and a control module. The base serves as a support structure for the leveling device 1, allowing it to rest on the ground; in this case, the base has a frame structure. Alternatively, the leveling device 1 can be mounted on a support frame or a traveling frame, with the base acting as a connector to connect the adjusting component 10 to the support frame or traveling frame. In this case, the base can be a seat structure for connection, or it can be the housing of the adjusting component 10, without limitation. The adjusting component 10 is connected to the base, making the base the mounting foundation for the adjusting component 10. The mounting frame 20 is adapted to connect to a hole environment detection device 30. The mounting frame 20 is provided with mounting holes that match the housing of the hole environment detection device 30, allowing the housing of the hole environment detection device 30 to be inserted into the mounting holes and connected to the mounting frame 20. The connection method between the mounting frame 20 and the hole environment detection device 30 is not limited; for example, bolt connection, snap-fit, or welding are not restricted.

[0058] A level is mounted on the mounting bracket 20. The level can be positioned on the top surface of the mounting bracket 20, and the plane containing the top surface of the mounting bracket 20 is parallel to the level of the mounting bracket 20. The level is used to detect the levelness of the mounting bracket 20. When the level is level, the mounting bracket 20 is also level. The level can be an electronic level or a six-axis sensor; there are no restrictions. Figure 3 and Figure 4As shown, the mounting frame 20 is connected to the adjustment assembly 10 via a transmission connection, allowing the attitude of the mounting frame 20 to be adjusted via the adjustment assembly 10. This adjustment, in turn, adjusts the attitude of the hole environment detection device 30 connected to the mounting frame 20. When the top surface of the mounting frame 20 is parallel to the horizontal plane, the detection pendant of the hole environment detection device 30 is perpendicular to the horizontal plane. The control module is electrically connected to the level and the adjustment assembly 10. Based on the deflection angle information of the mounting frame 20 fed back by the level, the control module drives the adjustment assembly 10 to adjust the spatial attitude of the mounting frame 20, ensuring that the level is parallel to the horizontal plane.

[0059] The leveling device 1 provided in this embodiment is connected to the hole environment detection device 30 via the mounting frame 20. After the device is moved into place, if the mounting frame 20 and the connected hole environment detection device 30 tilt due to uneven terrain, the control module can automatically drive the adjustment component 10 to adjust the spatial posture of the mounting frame 20 based on the deflection angle data fed back by the level instrument, so as to ensure that the mounting frame 20 always maintains a horizontal state, so as to synchronously correct the posture of the hole environment detection device 30, so that the initial falling direction of the detection pendant is precisely aligned with the axis of the blast hole, establishing a reliable benchmark for subsequent detection operations, thereby significantly improving the accuracy of the detection results of the hole environment detection device 30.

[0060] In some implementations, combined Figures 5 to 7 As shown, the adjustment assembly 10 includes a base plate 11 and a boom 12, a first adjustment arm 13, and a second adjustment arm 14 disposed on the base plate 11. The base plate 11 is connected to the base, wherein the base plate 11 and the base can be directly connected or indirectly connected through other structures, without limitation. The mounting frame 20 is rectangular and has corresponding first and second sides along the horizontal direction. The boom 12 is connected to the middle of the first side of the mounting frame 20 and is located above the mounting frame 20. The second side has corresponding first and second ends. The first adjustment arm 13 and the second adjustment arm 14 are respectively connected to the first and second ends, and both the first adjustment arm 13 and the second adjustment arm 14 are located above the mounting frame 20 to avoid affecting the connection between the mounting frame 20 and the hole environment detection device 30. The first adjustment arm 13 is configured to adjust the height of the first end, and the second adjustment arm 14 is configured to adjust the height of the second end, thereby adjusting the posture of the mounting frame 20.

[0061] In use, the leveling device 1 is placed in the corresponding position, and the levelness of the mounting bracket 20 is detected by a spirit level. If the X-axis deflection angle of the mounting bracket 20 is +2.5°, the control module calculates the extension and retraction of the first adjusting arm 13 and the second adjusting arm 14, and outputs a signal to control the first adjusting arm 13 and the second adjusting arm 14 to extend or retract respectively, until the X-axis angle of the mounting bracket 20 returns to ±0.05°, and the Y-axis is adjusted similarly. During the adjustment process, the spirit level continuously provides angle information, and the control module adjusts the first adjusting arm 13 and the second adjusting arm 14 in real time, forming a closed-loop control, until both the X and Y axis angles meet the level threshold requirements. The control module then outputs a leveling completion signal, and the hole environment detection device 30 can start detection.

[0062] In this design, the adjustment component 10 forms a three-point support with the boom 12, the first adjustment arm 13, and the second adjustment arm 14, which conforms to the principle of triangular stability. This effectively distributes the weight of the mounting frame 20 and the hole environment detection device 30, preventing posture swaying or displacement during the leveling process. Furthermore, the three-point support can accurately lock the horizontal reference of the mounting frame 20, ensuring that the mounting frame 20 does not twist or shift when the adjustment arm is adjusted in height, thus providing a stable structural foundation for the level instrument detection and control module adjustment.

[0063] In some implementations, combined Figures 5 to 7 As shown, the first adjusting arm 13 includes a first driving member 131, a first rotating arm 132, and a first adjusting rod 133. The first driving member 131 is connected to the base plate 11, and the first adjusting rod 133 is connected to the first driving member 131 via the first rotating arm 132. The first driving member 131 drives the first rotating arm 132 to rotate, and the axis of rotation of the first rotating arm 132 is parallel to the horizontal plane. The first adjusting rod 133 is perpendicular to the horizontal plane. One end of the first adjusting rod 133 is hinged to the end of the first rotating arm 132 away from the first driving member 131, and the other end of the first adjusting rod 133 is hinged to the first end of the second side of the mounting bracket 20, so that the first rotating arm 132 is swung by the first driving member 131, and the first adjusting rod 133 and the first end of the second side of the mounting bracket 20 connected thereto are moved vertically by the first rotating arm 132. The other end of the first adjusting rod 133 can be hinged to the first end of the second side of the mounting bracket 20 via a ball joint. The outer circumference of the ball joint is covered with a first protective sleeve to ensure the bearing sealing effect and enable the ball joint to swing at a large angle. Alternatively, the bottom end of the first adjusting rod 133 can be connected to the mounting bracket 20 via elastic blocks such as rubber blocks to enable multi-angle swing between the two without restriction.

[0064] In this design, the first driving component 131 drives the first rotating arm 132 to swing around the horizontal axis. Through the linkage structure, the circular swing of the rotating arm is converted into the vertical linear motion of the first adjusting rod 133. This precise conversion of motion can directly and stably drive the corresponding end of the mounting frame 20 to adjust its height, ensuring the accuracy of the leveling action. Furthermore, the first driving component 131 is located on one side of the mounting frame 20, reducing the space occupied in the vertical direction and making the structure more compact.

[0065] In some examples, the first adjusting arm 13 includes a first adjusting seat 134, which is connected to the base plate 11 and extends vertically downward. The first driving member 131 includes a first motor 1311, a first reducer 1312, and a first synchronous belt. The first motor 1311 has a power of 75W and an operating angle of ±15°. The first motor 1311 is connected to the side of the first adjusting seat 134 facing away from the mounting bracket 20, and the end face of the first motor 1311 is sealed to the first adjusting seat 134 by a sealing ring. The first reducer 1312 is connected to the side of the first adjusting seat 134 facing the mounting bracket 20, and the end face of the first reducer 1312 is sealed to the first adjusting seat 134 by a sealing ring. The height of the first reducer 1312 is higher than the height of the first motor 1311, and the output shaft of the first motor 1311 extends into the first adjusting seat 1311. Inside 4, the output shaft of the first motor 1311 is provided with a first driving pulley, the input shaft of the first reducer 1312 extends into the interior of the first adjusting seat 134, the input shaft of the first reducer 1312 is provided with a first driven pulley, the first synchronous belt is sleeved on the first driving pulley and the first driven pulley, so that the first driving pulley can drive the first synchronous belt to circulate and transport, so as to drive the first driven pulley to rotate synchronously, and the output shaft of the first reducer 1312 is connected to the end of the first rotating arm 132 that is away from the first adjusting rod 133.

[0066] In some specific examples, the output end face of the output shaft of the first reducer 1312 is provided with a first cover, the output end face of the first reducer 1312 is provided with a first sealing groove, and a second sealing groove is provided at the position corresponding to the first sealing groove on the first cover. A first sealing ring is provided in the first sealing groove and the second sealing groove to prevent dirt from entering the interior of the component and to avoid affecting the adjustment accuracy on that side.

[0067] In this design, the first adjusting seat 134 extends vertically downwards, and the first motor 1311 is arranged on the side away from the mounting frame 20, while the first reducer 1312 is arranged on the side facing the mounting frame 20 and is higher than the motor height. This staggered layout can effectively compress the horizontal space occupied by the first adjusting arm 13, avoid interference with the base, mounting frame 20 and other surrounding components, and the vertical structure can also make the transmission components compactly arranged in the vertical direction. Furthermore, the first driving pulley, the first driven pulley and the first synchronous belt are all integrated inside the first adjusting seat 134, avoiding the transmission components from being exposed to the outside, effectively isolating dust, gravel and other impurities at the mine site, and reducing the risk of wear and jamming of the transmission components.

[0068] In some implementations, reference continues. Figures 5 to 7 The second adjusting arm 14 includes a second driving member 141, a second rotating arm 142, and a second adjusting rod 143. The second driving member 141 is connected to the base plate 11, and the second adjusting rod 143 is connected to the second driving member 141 via the second rotating arm 142. The second driving member 141 drives the second rotating arm 142 to rotate. The axis of rotation of the second rotating arm 142 is parallel to the horizontal plane, and the first rotating arm 132 and the second rotating arm 142 are arranged opposite each other to reduce space occupation. The second adjusting rod 143 is perpendicular to the horizontal plane. One end of the second adjusting rod 143 is hinged to the end of the second rotating arm 142 away from the second driving member 141, and the other end of the second adjusting rod 143 is hinged to the second end of the second side of the mounting bracket 20, so that the second rotating arm 142 is swung by the second driving member 141, and the second adjusting rod 143 and the second end of the second side of the mounting bracket 20 connected thereto are moved vertically by the second adjusting arm 142. Figure 8 As shown, the other end of the second adjusting rod 143 can be hinged to the second end of the second side of the mounting bracket 20 via a ball joint. The outer circumference of the ball joint is covered with a second protective sleeve to ensure the bearing sealing effect and to enable the ball joint to swing at a large angle. Alternatively, the bottom end of the second adjusting rod 143 can be connected to the mounting bracket 20 via elastic blocks such as rubber blocks to enable multi-angle swing between the two without restriction.

[0069] In this design, the second drive member 141 drives the second rotating arm 142 to swing around the horizontal axis. Through the linkage structure, the circular swing of the rotating arm is converted into the vertical linear motion of the second adjusting rod 143. This precise conversion of motion can directly and stably drive the corresponding end of the mounting frame 20 to adjust the height, ensuring the accuracy of the leveling action. Moreover, the second drive member 141 is located on one side of the mounting frame 20, reducing the space occupied in the vertical direction and making the structure more compact.

[0070] In some examples, the second adjusting arm 14 includes a second adjusting seat 144 connected to the base plate 11 and extending vertically downwards. The second driving member 141 includes a second motor 1411, a second reducer 1412, and a second synchronous belt. The power of the second motor 1411 is 75W, and the operating angle of the second motor 1411 is ±15°. The second motor 1411 is connected to the side of the second adjusting seat 144 facing away from the mounting bracket 20, and the end face of the second motor 1411 is sealed to the second adjusting seat 144 by a sealing ring. The second reducer 1412 is connected to the side of the second adjusting seat 144 facing the mounting bracket 20, and the end face of the second reducer 1412 is sealed to the second adjusting seat 144 by a sealing ring. The height of the second reducer 1412 is higher than the height of the second motor 1411, and the output shaft of the second motor 1411 extends into the second adjusting seat 1411. Inside 4, the output shaft of the second motor 1411 is provided with a second driving pulley, the input shaft of the second reducer 1412 extends into the interior of the second adjusting seat 144, the input shaft of the second reducer 1412 is provided with a second driven pulley, the second synchronous belt is sleeved on the second driving pulley and the second driven pulley, so that the second driving pulley can drive the second synchronous belt to circulate and transport, so as to drive the second driven pulley to rotate synchronously, and the output shaft of the second reducer 1412 is connected to the end of the second rotating arm 142 that is away from the second adjusting rod 143.

[0071] In some specific examples, the output end face of the output shaft of the second reducer 1412 is provided with a second cover, the output end face of the second reducer 1412 is provided with a third sealing groove, and a fourth sealing groove is provided at the position corresponding to the third sealing groove on the second cover. A second sealing ring is provided in the third sealing groove and the fourth sealing groove to prevent dirt from entering the interior of the component and to avoid affecting the adjustment accuracy on that side.

[0072] In this design, the second adjusting seat 144 extends vertically downwards, and the second motor 1411 is arranged on the side away from the mounting frame 20, while the second reducer 1412 is arranged on the side facing the mounting frame 20 and is higher than the motor height. This staggered layout can effectively compress the horizontal space occupied by the second adjusting arm 14, avoid interference with the base, mounting frame 20 and other surrounding components, and the vertical structure can also make the transmission components compactly arranged in the vertical direction. Furthermore, the second driving pulley, the second driven pulley and the second synchronous belt are all integrated inside the second adjusting seat 144, avoiding the transmission components from being exposed to the outside, effectively isolating dust, gravel and other impurities at the mine site, and reducing the risk of wear and jamming of the transmission components.

[0073] In some implementations, combined Figures 1 to 7As shown, the boom 12 is connected to the mounting frame 20 via a boom 121. The top end of the boom 121 is hinged to the boom 12, and the hinge axis of the boom 121 is parallel to the horizontal plane and perpendicular to the rotation axis of the first rotating arm 132. The bottom end of the boom 121 is hinged to the mounting frame 20. The bottom end of the boom 121 and the mounting frame 20 can be hinged via a ball joint, such as... Figure 12 As shown, the outer circumference of the ball shaft is provided with a third protective sleeve 122 to ensure the bearing sealing effect and at the same time enable the ball shaft to swing at a large angle; or the bottom end of the hanger 121 and the mounting bracket 20 can be moved together by elastic blocks such as rubber blocks to enable multi-angle swing between the two without restriction.

[0074] In this design, the hinge shaft at the top of the boom 121 is arranged perpendicularly to the pivot shaft of the first rotating arm 132, forming a cross-shaped hinged degree of freedom. This structure allows the mounting frame 20 to flexibly deflect in both the X and Y axes on the horizontal plane, without restricting the leveling action of the first adjusting arm 13 and the second adjusting arm 14 due to the fixed connection of the boom 12, ensuring that the posture adjustment of the mounting frame 20 is uninterrupted during the leveling process.

[0075] In some implementations, combined Figures 1 to 4 As shown, the adjustment assembly 10 includes a fourth driving member 16. The substrate 11 is connected to the base through the fourth driving member 16. The substrate 11 and the output shaft of the fourth driving member 16 can be directly connected or indirectly connected, without limitation. The fourth driving member 16 is used to drive the substrate 11 to rotate, and the rotation axis of the substrate 11 is perpendicular to the horizontal plane.

[0076] In this design, the fourth drive component 16 drives the base plate 11 to rotate around the vertical axis, which can simultaneously drive the mounting frame 20 and the hole environment detection device 30 to rotate horizontally. Even if there is an angular deviation between the initial placement position of the leveling device 1 and the blast hole, there is no need to manually move the whole machine. The orientation can be adjusted directly by the fourth drive component 16 to ensure that the initial falling direction of the detection pendant is precisely aligned with the axis of the blast hole, thereby further eliminating positioning errors.

[0077] In some implementations, reference continues. Figures 1 to 4 The adjustment assembly 10 also includes a third driving member 15. The substrate 11 is connected to a fourth driving member 16 via the third driving member 15. Specifically, the output shaft of the third driving member 15 is connected to the substrate 11. The third driving member 15 is used to drive the substrate 11 to rotate, and the rotation axis of the substrate 11 is perpendicular to the horizontal plane. The output shaft of the fourth driving member 16 is connected to the third driving member 15, and the fourth driving member 16 is used to drive the third driving member 15 to rotate. The rotation axis of the third driving member 15 is perpendicular to the horizontal plane.

[0078] In this design, the double-layer vertical rotation structure enables the superimposed rotational motion of the substrate 11, breaking through the rotation angle limitation of a single driving component and allowing the mounting frame and the hole environment detection device 30 connected to it to be adjusted at any position within a certain range. The fourth driving component 16 can drive the substrate 11 to achieve large-angle rapid rotation, which is used to quickly align the approximate location of the blast hole. The third driving component 15 is responsible for small-angle fine-tuning, controlling the alignment error between the falling direction of the detection pendant and the axis of the blast hole within a very small range. This graded adjustment mode takes into account both rotation angle and alignment efficiency and accuracy, solving the problem that a single driving component cannot simultaneously meet the requirements of large-range rapid adjustment and high-precision calibration.

[0079] In some implementations, combined Figures 1 to 4 As shown, the adjustment assembly 10 also includes a rotating plate 17, which extends horizontally. One end of the rotating plate 17 is connected to a fourth driving member 16, which drives the rotating plate 17 to rotate and is located above the rotating plate 17. The other end of the rotating plate 17 is connected to a third driving member 15, which is located below the rotating plate 17. The output shaft of the third driving member 15 extends vertically and is fixedly connected to the rotating plate 17. The base plate 11 is fixedly connected to the third driving member 15.

[0080] In use, the fourth driving member 16 can drive the rotating plate 17 to rotate, which in turn drives the third driving member 15 and the substrate 11 to rotate. The output shaft of the third driving member 15 is fixedly connected to the rotating plate 17. Therefore, when the third driving member 15 drives its output shaft to rotate, the third driving member 15 itself will rotate around the rotating shaft, which in turn drives the substrate 11 to rotate.

[0081] In this design, the fourth drive component 16 is located above the rotating plate 17, and the third drive component 15 is located below the rotating plate 17, forming a compact structure with upper and lower layers. This design can avoid the problem of excessive vertical height caused by the coaxial arrangement of the two drive components and effectively reduce the overall height of the adjustment component 10.

[0082] In some implementations, combined Figure 10 and Figure 11As shown, the fourth driving component 16 includes a fourth motor 161, a fourth reducer 162, and a fourth synchronous belt 163. The power of the fourth motor 161 is 1000W, and the movement angle of the fourth motor 161 is ±180°. The fourth motor 161 is connected to a base, which can be the housing of the fourth reducer 162. The fourth reducer 162 is connected to the top of the rotating plate 17, and the output shaft of the fourth reducer 162 is connected to the rotating plate 17. The housing of the fourth motor 161 and the housing of the fourth reducer 162 are connected through a connecting seat 18. The housing of the fourth reducer 162 is rotatably connected to the rotating plate 17, and the end face of the fourth reducer 162 is sealed to the rotating plate 17 by a sealing ring. The output shaft of the fourth motor 161 extends into the interior of the connecting seat 18, and the end face of the fourth motor 161 is sealed to the connecting seat 18 by a sealing ring. The output shaft of the fourth motor 161 is equipped with a fourth driving pulley. The input shaft of the fourth reducer 162 extends into the interior of the connecting seat 18, and the end face of the fourth reducer 162 is sealed to the connecting seat 18 by a sealing ring. The input shaft of the fourth reducer 162 is equipped with a fourth driven pulley. A fourth synchronous belt 163 is fitted over the fourth driving pulley and the fourth driven pulley, enabling the fourth driving pulley to drive the fourth synchronous belt 163 to circulate and transport, thereby driving the fourth driven pulley to rotate synchronously, and consequently causing the rotating plate 17 to rotate relative to the housing of the fourth reducer 162. The fourth driving pulley, the fourth driven pulley, and the fourth synchronous belt 163 are all integrated inside the connecting seat 18, preventing the transmission components from being exposed and reducing environmental pollution.

[0083] In some implementations, such as Figure 9 As shown, the substrate 11 extends in a direction away from the mounting bracket 20, and the substrate 11 is provided with a mounting cavity 111; the third drive member 15 includes a third motor 151, a third reducer 152 and a third synchronous belt 153, the power of the third motor 151 is 750W, and the movement angle of the third motor 151 is ±90°. The third motor 151 is located at the bottom of the substrate 11 away from the mounting bracket 20. The end face of the third motor 151 is sealed to the substrate 11 by a sealing ring. The output shaft of the third motor 151 extends into the mounting cavity 111. The output shaft of the third motor 151 is provided with a third driving pulley. The third reducer 152 is located at the top of the substrate 11 near the mounting bracket 20. The input shaft of the third reducer 152 extends into the mounting cavity 111. The input shaft of the third reducer 152 is provided with a third driven pulley. The third synchronous belt 153 is sleeved on the third driving pulley and the third driven pulley. The output shaft of the third reducer 152 is fixedly connected to the rotating plate 17. The housing of the third reducer 152 is rotatably connected to the rotating plate 17. The end face of the third reducer 152 is sealed to the rotating plate 17 by a sealing ring.

[0084] In this design, the third driving pulley, the third driven pulley, and the third synchronous belt 153 are all integrated into the mounting cavity 111 of the base plate 11, avoiding the exposure of transmission components. This design can effectively isolate dust, gravel, and other impurities at the mine site, reduce the wear and jamming risk of transmission components, and significantly reduce the external space occupied by the third drive component 15. The third motor 151 is arranged at the bottom of the base plate 11 away from the mounting bracket 20, and the third reducer 152 is arranged at the top of the base plate 11 near the mounting bracket 20. The two are connected by the synchronous belt in the mounting cavity 111 to transmit power. This staggered layout allows the power transmission path to conform to the extension direction of the base plate 11, avoiding interference between the transmission structure and surrounding components, and making the overall structure of the adjustment component 10 more compact.

[0085] In this design, the leveling device 1 adjusts the position of the hole environment detection device 30 through the third drive component 15 and the fourth drive component 16, and adjusts the posture of the hole environment detection device 30 through the first adjusting arm 13 and the second adjusting arm 14. The third drive component 15, the fourth drive component 16, the first adjusting arm 13, and the second adjusting arm 14 form a position and posture linkage adjustment mechanism, which can achieve automated adjustment through a unified control system, eliminating the need for manual adjustment and reducing the labor intensity of operators. Each drive component and adjusting arm adopts a modular design and uses a rotary drive method to reduce the relative displacement between components. The structure is compact and has a strong load-bearing capacity, which can adapt to the harsh working conditions such as high-frequency vibration and high dust in the mine. Moreover, the synchronous belt transmission is less affected by external factors, ensuring transmission accuracy. The leveling device 1 in this way is also convenient for later maintenance and component replacement, further extending the service life of the equipment and improving the reliable operation capability of the equipment in complex working environments.

[0086] like Figure 13 As shown, this application also provides a leveling device, including a leveling vehicle 2 and the aforementioned leveling device 1, wherein the leveling device 1 includes all the technical features of the aforementioned leveling device 1. The leveling vehicle 2 includes a frame 200 and a plurality of wheels 210 disposed on the frame 200. The base of the leveling device 1 is connected to the bottom of the frame 200, and the bottom of the wheels 210 extends downward out of the leveling device 1. The base of the leveling device 1 may be the housing of the fourth motor 161, or one side of the base may be connected to the housing of the fourth motor 161, and the other side of the base may be connected to the bottom of the frame 200. When the hole environment detection device 30 is connected to the mounting bracket 20, the bottom of the wheels 210 should also extend downward out of the bottom of the hole environment detection device 30.

[0087] In this design, the leveling device 1 is mounted on the frame 200 with wheels 210, which can be quickly moved to different blast hole detection points without the need for manual handling of heavy equipment, thus increasing the efficiency of transportation. The design of the leveling device 1 extending from the bottom of the wheels 210 ensures that the leveling device 1 will not scrape against the ground when the equipment is moved, taking into account both mobility and structural protection.
