Description

Technical Field

[0002] Photovoltaic power generation in the desert typically requires installing multiple photovoltaic panels, which convert sunlight into electricity. The panels are supported on the desert sand by support structures (such as support columns). During installation, a drilling device is typically used to drill holes in the desert sand, and then the support structure is installed in the drilled holes.

[0003] At present, drilling is usually performed manually by driving a drilling device and manipulating a drilling tool. When multiple photovoltaic panels need to be installed, the drilling device needs to be driven to move the position so as to perform drilling operations one by one multiple times to obtain multiple hole positions. The position of the hole is determined by manually moving the drilling device multiple times. This drilling method has problems such as low accuracy of the drilling position and low efficiency of the drilling operation. Utility Model Content

By adjusting the mounting platform to a horizontal position, the drilling tool can avoid deviation in the drilling position during drilling, further improving drilling position accuracy.

[0035] Furthermore, the drilling device includes a fine-adjustment mechanism. Since the fine-adjustment mechanism is disposed on the mounting platform and fixedly connected to the drilling tool, the fine-adjustment mechanism can drive the drilling tool to move in a first direction relative to the mounting platform. Thus, the fine-adjustment mechanism can precisely adjust the position of the drilling tool. By improving the accuracy of adjusting the drilling tool position, the accuracy of the drilling position can be improved.

[0036] Furthermore, the auxiliary fixing mechanism is connected to the drilling tool and to the connecting rod and / or the mounting platform, and can move relative to the mounting platform. The auxiliary fixing mechanism can improve the stability of the drilling tool when moving relative to the mounting platform.

[0037] Furthermore, adjacent drilling tools are connected by cross bars, which can maintain the relative positions between adjacent drilling tools and help to further improve the accuracy of drilling positions. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] As mentioned in the background art, existing drilling equipment has problems of poor drilling accuracy and low working efficiency of drilling operations.

[0066] In order to solve the above technical problems, an embodiment of the present application provides a drilling device, including: a mounting platform; a plurality of sets of drilling tools, which are distributed at intervals and integrated on the mounting platform; a motion mechanism, connected to the mounting platform, for driving the mounting platform to move in at least one direction; during the period when the motion mechanism drives the mounting platform to move and / or during the operation of the drilling tools, the relative positions between adjacent drilling tools remain unchanged.

[0067] By adopting the technical solution of the embodiment of the present application, multiple sets of drilling tools are integrated on a single mounting platform to achieve synchronous drilling, thereby ensuring the accuracy of the layout of multiple holes. Multiple holes arranged according to preset requirements can be drilled at one time, greatly reducing the positional error between holes.

[0068] Furthermore, when the drilling device is processed or assembled, the distance between multiple sets of drilling tools 2 can be reasonably set according to actual needs. Subsequently, the relative positions between adjacent drilling tools 2 remain unchanged during the movement of the drilling device and the implementation of the drilling operation, so that the drilled holes meet the preset requirements and improve the drilling accuracy and efficiency of the drilling operation.

[0069] Furthermore, by driving the mounting platform in at least one direction through the motion mechanism, the drilling tool on the mounting platform can also be moved to adjust the drilling position, thereby allowing the mounting platform and the drilling tool carried on the mounting platform to quickly move to and align with the target drilling position to perform the drilling operation. By operating the drilling device of this embodiment, multiple drilling tools can be operated simultaneously, significantly improving the drilling operation efficiency of the drilling device.

[0070] In order to make the above-mentioned objectives, features and beneficial effects of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0071] Figure 1 This is a schematic diagram of a drilling device 100 according to an embodiment of the present application.

[0072] refer to Figure 1 The drilling device 100 includes a mounting platform 1; multiple sets of drilling tools 2 spaced apart and integrated with the mounting platform 1; and a motion mechanism 3 connected to the mounting platform 1 for driving the mounting platform 1 in at least one direction. The multiple sets of drilling tools 2 are used for drilling holes in places such as the ground and deserts.

[0073] Thus, multiple sets of drilling tools 2 are integrated on a single mounting platform 1, achieving synchronized drilling and ensuring the accuracy of the layout of multiple holes. Multiple holes arranged according to preset requirements can be drilled at one time, greatly reducing the positional errors between holes. Furthermore, the motion mechanism 3 drives the mounting platform 1 to move in at least one direction, and can also drive the drilling tool 2 on the mounting platform 1 to move and adjust the drilling position, so that the mounting platform 1 and the drilling tool 2 supported on the mounting platform 1 can be quickly moved to and aligned with the target drilling position to perform the drilling operation. By operating the drilling device 100 of this embodiment, multiple drilling tools 2 can be operated simultaneously at one time, significantly improving the drilling operation efficiency of the drilling device 100.

[0074] Further, combined Figure 27In addition to multiple sets of drilling tools 2, the mounting platform 1 may also be equipped with various electrical components, such as an electrical box 90 located in the middle of the mounting platform 1, which is used to control the movement of various components on the mounting platform 1 (such as the drilling tools 2 and the motion mechanism 3). For another example, multiple water tanks 91 located on either side of the electrical box 90 are used to pump water to each set of drilling tools 2 during drilling. In some non-limiting embodiments, the at least one direction may include: the direction of travel of the drilling device 100, a direction within the plane of the mounting platform 1 that intersects the direction of travel of the drilling device 100 (such as a direction perpendicular to the direction of travel), a direction perpendicular to the plane of the mounting platform 1, and a direction of rotation within the plane of the mounting platform 1.

[0075] For ease of description, the length direction of the drilling device 100 is referred to as the y-direction, the width direction of the drilling device 100 is referred to as the x-direction, and the height direction of the drilling device 100 is referred to as the z-direction. Accordingly, the x-direction and y-direction are the travel direction of the aforementioned mounting platform 1 and the direction intersecting with it within the plane of the mounting platform 1, respectively. The z-direction is the direction perpendicular to the plane of the mounting platform 1.

[0076] In some non-limiting embodiments, the direction of travel of the drilling device 100 is recorded as the first direction. The second direction intersects with the direction of travel of the drilling device 100 in the plane where the mounting platform 1 is located, that is, the first direction intersects with the second direction. For example, the first direction is perpendicular to the second direction. It should be noted that the drawings provided in this embodiment are illustrated by taking the first direction and the second direction as an example. The second direction in the figure refers to the positive and negative directions of x, the first direction is the positive and negative directions of y, and the third direction is the positive and negative directions of z. It can be understood that the angle at which the first direction intersects with the second direction can also be 15°, 30°, 45°, etc. The specific value of the angle at which the first direction and the second direction intersect can be configured according to actual needs, and examples will not be given here one by one.

[0077] In some non-limiting embodiments, the drilling centers of the respective sets of the drilling tools 2 are on the same straight line. Figure 1 The line connecting the centers of the holes drilled by the four sets of drilling tools 2 shown can be parallel to the y-direction. In practical applications, the number of drilling tools 2 installed on a single mounting platform 1 can be adjusted as needed, such as 3, 5, or 8 sets. Thus, after the drilling operation, multiple holes with centers aligned on the same straight line can be obtained, facilitating the subsequent installation of arrayed photovoltaic panels. In one variation, the centers of the holes drilled by the various sets of drilling tools 2 can be arranged in different directions, such as in a wavy pattern or in a multi-row array, to accommodate the installation requirements of photovoltaic panels with different arrangements.

[0078] Furthermore, the line connecting the drilling centers of each set of drilling tools 2 passes through the rotation center of the plane of the mounting platform 1, wherein the plane of the mounting platform 1 is perpendicular to the extension direction (e.g., the z-direction) of the drilling tools 2. This allows the center of gravity of the system consisting of multiple sets of drilling tools 2 to coincide with the projection of the center of gravity of the mounting platform 1 along the direction of gravity (e.g., the z-direction), thereby ensuring the stability of the entire drilling device 100.

[0079] In some embodiments, while the movement mechanism 3 drives the installation platform 1 to move, the relative positions of adjacent drilling tools 2 remain unchanged.

[0080] In some embodiments, adjacent drilling tools 2 are connected by a cross bar 4 .

[0081] Specifically, when there are multiple sets of drilling tools 2, the drilling apparatus 100 further includes a crossbar 4, which connects adjacent drilling tools 2. Thus, the crossbar 4 not only maintains and fixes the relative distance between adjacent drilling tools 2, but also connects multiple sets of drilling tools 2 into a single unit, thereby enhancing the overall structural stability of the drilling apparatus 100.

[0082] In some embodiments, the crossbars 4 in various drilling devices 100 may have the same or different sizes. The specific size of the crossbars 4 may be configured according to the required hole spacing of the drilling device 100. The hole spacing refers to the distance between adjacent holes.

[0083] In some non-limiting embodiments, the crossbar 4 can be configured as a telescopic structure, so that the length of the crossbar 4 can be flexibly adjusted according to the punching spacing.

[0084] Furthermore, the motion mechanism 3 includes a travel mechanism 31 mounted on the mounting platform 1 and configured to drive the mounting platform 1 to move in a first direction parallel to the plane of the mounting platform 1. For example, the first direction may include the direction of travel of the mounting platform 1, such as the y-direction or the x-direction. Thus, the travel mechanism 31 facilitates and expedites the movement of the drilling apparatus 100, thereby improving the efficiency of the drilling operation.

[0085] In some non-limiting embodiments, the travel mechanism 31 is a crawler mechanism. For example, a pair of crawlers can be provided on opposite sides of the mounting platform 1 along the x-direction, with each pair of crawlers including two crawlers spaced apart along the y-direction, for a total of four crawlers.

[0086] In a variation, the traveling mechanism 31 may also be other suitable traveling mechanisms, such as wheels.

[0087] Further, refer to Figures 1 to 4The motion mechanism 3 further includes a swivel mechanism 32 for driving the travel mechanism 31 and the mounting platform 1 in relative rotation. Thus, by adjusting the position relative to the target drilling position via the swivel mechanism 32, after the travel mechanism 31 reaches the target drilling position, it may not be possible to ensure that the arrangement direction of the multiple sets of drilling tools 2 is parallel to the line containing the target drilling positions. In this case, rotating the mounting platform 1 so that the line connecting the multiple sets of drilling tools 2 is parallel to the line containing the target drilling positions can improve drilling accuracy.

[0088] In some embodiments, corresponding drive devices can be configured for the slewing mechanism 32 and the traveling mechanism 31. When the slewing mechanism 32 is required to operate, the drive device corresponding to the slewing mechanism 32 (referred to as the first drive device 5) is activated. When the traveling mechanism 31 is required to operate, the drive device corresponding to the traveling mechanism 31 (referred to as the second drive device 50) is activated. For either the first drive device 5 or the second drive device 50, the drive device can be, for example, a motor.

[0089] Specifically, each crawler mechanism can be configured with a corresponding second drive device 50 for driving the corresponding crawler. In response to only one crawler of the two crawlers opposite each other in the x-direction being driven by the corresponding second drive device 50, the drilling device 100 can be rotated toward the inactive crawler to achieve steering.

[0090] Furthermore, the motion mechanism 3 may further include a transmission module 33 for transmitting the power of the first drive device 5 to the rotary mechanism 32 to drive the travel mechanism 31 to rotate relative to the installation platform 1. The transmission module 33 may achieve transmission through mechanical means such as a gear transmission structure.

[0091] For example, the transmission module 33 includes a transmission tooth 331, and the rotating mechanism 32 includes a first tooth 321. The transmission tooth 331 is engaged with the first tooth 321. The power of the first driving device 5 is transmitted to the rotating mechanism 32 via the transmission tooth 331 and the first tooth 321 to drive the mounting platform 1 to rotate relative to the travel mechanism 31.

[0092] In a typical application scenario, when the entire drilling device moves to the preset drilling position through the traveling mechanism 31, the arrangement direction of multiple sets of drilling tools is not parallel to the arrangement direction of the preset drilling points. At this time, the rotating mechanism 32 can be driven by the first driving device 5 to rotate around the axis in the z direction, thereby driving the mounting platform 1 to rotate relative to the traveling mechanism 31 in the plane where the mounting platform 1 is located, until the arrangement direction of multiple sets of drilling tools is parallel to the arrangement direction of the preset drilling points, so as to facilitate further position adjustment of the drilling tools.

[0093] In one variation, the rotary mechanism 32 and the travel mechanism 31 can share a common drive device. Specifically, a transmission mechanism can be added to control the drive device's transmission connection with one of the rotary mechanism 32 and the travel mechanism 31, and disconnect it from the other. This simplifies the overall structure of the drilling device 100, reducing production and manufacturing costs.

[0094] For example, the driving device can be connected to one of the rotating mechanism 32 and the traveling mechanism 31 through a circuit control method such as a control module.

[0095] In some embodiments, reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 The drilling device 100 further includes a position adjustment mechanism 34 for driving the mounting platform 1 to move in a second direction, wherein the first direction and the second direction intersect within the plane of the mounting platform 1. For example, the first direction is the y-direction shown in the figure, and the second direction is the x-direction shown in the figure. For another example, the first direction is the x-direction shown in the figure, and the second direction is the y-direction shown in the figure.

[0096] In a specific embodiment, the position adjustment mechanism 34 includes at least one body 341, wherein each body 341 is connected to the mounting platform 1 via at least one set of adjustment components 342. For example, the position adjustment mechanism 34 may include a single body 341, wherein the single body 341 is connected to the mounting platform 1 via one or more sets of adjustment components 342. For another example, the position adjustment mechanism 34 may include multiple bodies 341, wherein each body 341 is connected to the mounting platform 1 via one or more sets of adjustment components 342, and the number of adjustment components 342 connected to different bodies 341 can be the same or different. Figure 1 and Figure 6 An example is given for illustrative demonstration using two bodies 341 , where each body 341 is connected to the mounting platform 1 via two adjustment components 342 .

[0097] Furthermore, the adjustment assembly 342 may include a moving assembly 3421 and a driving assembly 3422. One end of the moving assembly 3421 is movably connected to the body 341, and the other end of the moving assembly 3421 is connected to the mounting platform 1. The driving assembly 3422 is connected to the moving assembly 3421 to drive the moving assembly 3421 to move the mounting platform 1 in the second direction relative to the body 341.

[0098] From the above, the positions of multiple sets of drilling tools 2 can be adjusted in the traveling direction through the traveling mechanism 31, and the driving component 3422 in the position adjustment mechanism 34 can also drive the moving component 3421 to move, thereby driving the installation platform 1 to move. Since multiple sets of drilling tools 2 are connected to the installation platform 1, the second direction in the plane where the installation platform 1 is located intersects with the traveling direction of the drilling device 100 (for example, the y direction), so as to realize the adjustment of the positions of multiple sets of drilling tools 2 in the second direction, thereby improving the accuracy of the drilling position.

[0099] In some embodiments, the moving assembly 3421 may include: a track 34211 , which is disposed on the body 341 and extends along the second direction; and a roller assembly 34212 , which is connected to the mounting platform 1 and can move along the track 34211 .

[0100] Specifically, combined Figure 6 and Figure 7 The movable assembly 3421 may further include a bearing portion 34213. The bearing portion 34213 is connected to the mounting platform 1. The roller assembly 34212 is connected to the bearing portion 34213, supported by the body 341, and movable relative to the body 341 along the second direction (e.g., the x-direction). The bearing portion 34213 serves as a carrier for carrying the roller assembly 34212.

[0101] In some non-limiting embodiments, there are multiple roller assemblies 34212 to improve the movement stability of the moving assembly 3421. For example, the embodiment of the present application uses an example in which the position adjustment mechanism 34 includes two moving assemblies 3421, and each moving assembly 3421 includes four roller assemblies 34212.

[0102] Further reference Figure 7 The roller assembly 34212 includes a wheel axle a, a bearing b, a wheel c, and a locking portion d. The wheel axle a is fixedly connected to the support portion 34213. The wheel axle a is fixedly connected to the support portion 34213. The wheel c is mounted on the bearing b and rotates relative to the wheel axle a. The locking portion d is connected to the wheel axle a to restrict the wheel c from axially moving along the wheel axle a and disengaging from the wheel axle a.

[0103] Furthermore, the locking portion d includes a locking portion d1, a locking ring d2, and a locking screw d3. The locking portion d1 is connected to the end of the wheel axle a away from the bearing portion 34213 and abuts against the wheel c. The locking ring d2 is sleeved over the locking portion d1. The locking screw d3 passes through the locking ring d2 and the locking portion d1 to lock the locking ring d2 and the locking portion d1 to the wheel axle a.

[0104] Furthermore, the body 341 is provided with a track 34211, which is adapted to the roller assembly 34212 and is configured to guide the roller assembly 34212 to move along the second direction (e.g., the x-direction). Specifically, the track 34211 extends parallel to the second direction (e.g., the x-direction) to guide the roller assembly 34212 to reciprocate along the second direction (e.g., the x-direction).

[0105] In some embodiments, the body 341 has a cavity 3411 with an open top, and the cavity 3411 is used to accommodate at least a portion of the drive assembly 3422 and the movable assembly 3421. By accommodating at least a portion of the drive assembly 3422 and the movable assembly 3421 in the cavity 3411, interference between at least a portion of the drive assembly 3422 and the movable assembly 3421 and other components of the drilling device 100 can be avoided, thereby ensuring the normal operation of the drilling device 100.

[0106] Furthermore, the driving assembly 3422 includes: a driving motor 34221, which is arranged on the main body 341; a worm gear assembly 34222, which is connected to the driving motor 34221 and the roller assembly 34212, and the driving motor 34221 drives the roller assembly 34212 to move along the track 34211 through the worm gear assembly 34222.

[0107] In some non-limiting embodiments, the drive motor 34221 is stationary relative to the body 341. For example, the drive motor 34221 is connected to the body 341 and is stationary relative to the body 341. The worm gear assembly 34222 is connected to the drive motor 34221 and the supporting portion 34213. Driven by the drive motor 34221, the worm gear assembly 34222 causes the moving assembly 3421 to move relative to the body 341 along the second direction (e.g., the x-direction), thereby driving the supporting portion 34213 and the plurality of roller assemblies 34212 to move relative to the body 341 along the second direction (e.g., the x-direction).

[0108] Furthermore, the worm gear assembly 34222 includes a worm wheel and a worm, and the worm is adapted to the worm wheel. Through the cooperation of the worm and the worm wheel, the rotational motion of the drive motor 34221 can be converted into linear motion, thereby driving the roller assembly 34212 to move relative to the body 341 along the second direction (e.g., the x-direction).

[0109] In a typical application scenario, the position adjustment mechanism 34 can be installed on the installation platform 1 in a liftable manner. If the position adjustment mechanism 34 is lifted off the ground and the travel mechanism 31 contacts the ground, the position adjustment mechanism 34 is off the ground and is in a suspended state (such as Figure 2 As shown in the figure), the moving component 3421 is connected to the installation platform 1 and is fixed relative to the ground. At this time, the worm is also fixed relative to the ground. The driving motor 34221 drives the worm wheel to move relative to the worm. The driving motor 34221 is fixedly connected to the main body 341, thereby driving the main body 341 to move relative to the installation platform 1 along the second direction (for example, the x direction), thereby realizing the movement of the position adjustment structure 4 relative to the installation platform 1 along the second direction (for example, the x direction). If the position adjustment mechanism 34 descends to contact the ground and props up the entire mounting platform 1, causing the travel mechanism 31 to leave the ground, the position adjustment mechanism 34 is fixed relative to the ground, and the travel mechanism 31 is in a suspended state. Since the drive motor 34221 is fixedly connected to the main body 341, the drive motor 34221 is fixed relative to the ground. The worm moves relative to the ground under the drive motor 34221 and the worm gear. The worm is connected to the bearing portion 34213, so that the moving assembly 3421 moves relative to the main body 341, and the moving assembly 3421 drives the mounting platform 1 connected thereto to move in the second direction (for example, the x direction). By alternately contacting the ground with the position adjustment mechanism 34 and the travel mechanism 31, the position of multiple sets of drilling tools 2 can be continuously adjusted in the second direction (for example, the x direction), achieving precise positioning of the drilling position.

[0110] Furthermore, at least a portion of the drive assembly 3422 is accommodated within the cavity 3411, which means that a portion or all of the drive assembly 3422 is located within the cavity 3411. For example, a portion of the worm gear assembly 34222 of the drive assembly 3422 is located within the cavity 3411, wherein the worm gear can be located entirely within the cavity 3411, or partially within the cavity 3411 and partially outside the cavity 3411, and the drive motor 34221 can be located partially within the cavity 3411 or partially outside the cavity 3411. The relative positional relationship between the drive assembly 3422 and the cavity 3411 is configured according to actual needs, as long as it does not affect the normal operation of the drilling device 100.

[0111] In some embodiments, when the position adjustment mechanism 34 includes multiple moving components 3421, each moving component 3421 can be respectively configured with a corresponding driving component 3422 to independently control the moving component 3421; or a corresponding driving component 3422 can be configured for one of the moving components 3421, and the moving component 3421 configured with the driving component 3422 serves as an active moving component, and the moving component 3421 not configured with the driving component 3422 serves as a driven moving component, and the active moving component can drive the driven moving component to move.

[0112] In some non-limiting embodiments, the position adjustment mechanism 34 may include two bodies 341 , and the two bodies 341 are disposed on both sides of the moving mechanism 31 along the first direction.

[0113] Furthermore, each body 341 is connected to the mounting platform 1 via two sets of adjustment assemblies 342. The two sets of adjustment assemblies 342 provided on the same body 341 are spaced apart along the second direction. This ensures that the position adjustment mechanism 34 is more stable when adjusting the position of the drilling device 100, preventing accidents such as tipping over.

[0114] In some embodiments, reference Figure 1 、 Figure 2 and Figure 5 , the motion mechanism 3 may also include: a leveling component 35, connecting the moving component 3421 and the mounting platform 1 to adjust the angle between the mounting platform 1 and the horizontal plane. Thus, the leveling component 35 can be used to adjust the plane where the mounting platform 1 is located to a horizontal state. When multiple sets of drilling tools 2 are drilling, it can be ensured that the drilling direction is perpendicular to the horizontal direction, and it is not easy to deviate during drilling, thereby further improving the drilling accuracy. Among them, the horizontal state in the embodiment of the present application refers to an absolute horizontal state. The absolute horizontal state in this embodiment refers to a horizontal state relative to the ground plane where the drilling device 100 is located.

[0115] In some non-limiting embodiments, a level meter or angle sensor or other level detection device may be installed on the mounting platform 1. When the leveling assembly 35 adjusts the plane of the mounting platform 1, the level detection device can detect whether the mounting platform 1 is in a horizontal state.

[0116] In some embodiments, one end of a lifting assembly 351 is mounted perpendicular to the mounting platform 1, and the other end is hinged to the moving assembly 3421. The lifting assembly 351 is configured to drive the body 341 to move back and forth in a direction perpendicular to the plane of the mounting platform 1 (i.e., a third direction, such as the z direction shown in the figure). The lifting assembly 351 can be, for example, an electric push rod.

[0117] Specifically, refer to Figures 6 to 9The lifting assembly 351 includes a connecting portion 3511 and a mating portion 3512. The connecting portion 3511 is used to connect to the mounting platform 1. The mating portion 3512 is movably connected to the moving assembly 3421 and is adapted to fit the connecting portion 3511. Multiple position adjustment mechanisms 34 support the ground. The connecting portion 3511 can be configured to drive the mounting platform 1 to reciprocate in the z-direction perpendicular to the plane on which the mounting platform 1 is located until the plane on which the mounting platform 1 is located is adjusted to a horizontal state.

[0118] Furthermore, the connecting portion 3511 includes a fixing member 35111 and a movable member 35112. The fixing member 45111 is fixedly connected to the mounting platform 1. The movable member 35112 is movably connected to the fixing member 45111 and the matching portion 3512 and can move relative to the mounting platform 1 in the z direction.

[0119] In some non-limiting embodiments, the fixing member 35111 may be cylindrical and sleeved on the movable member 35112 .

[0120] In some embodiments, the movable member 35112 can be driven by the motor 352 to reciprocate along the third direction.

[0121] Continue to refer Figures 9 to 11 The movable member 35112 includes a rod portion e and a spherical connector f connected to the rod portion e. The rod portion e is movably connected to the fixed member 45111. The mating portion 3512 includes a ball seat 35121 and a locking member 35122. The ball seat 35121 is adapted to accommodate the spherical connector f. The locking member 35122 is used to confine the spherical connector f within the ball seat 35121.

[0122] Furthermore, the locking member 35122 may include a ball cap g and a ball cap locking portion h. Both the ball cap g and the ball cap locking portion h are provided with a hole for passing the rod e. The inner diameter of the hole in the ball cap g is smaller than the outer diameter of the rod e and larger than the ball diameter of the spherical connector f, thereby confining the spherical connector f within the ball seat 35121. The ball cap locking portion h is used to lock the ball cap g to the ball seat 35121.

[0123] Furthermore, a gap gap is defined between the locking member 35122 and the rod portion e, and the gap gap is configured as an offset space for the rod portion e.

[0124] In some non-limiting embodiments, in combination Figures 11 to 14The uppermost inner ring of the locking member 35122 is chamfered to form the gap. This gap is located at the uppermost end of the locking member 35122. The offset space provided by the gap allows the drilling device 100 to be leveled on sloped terrain. Specifically, when the drilling device 100 moves to a terrain with a certain slope, the main body 341 is driven by the lifting assembly 351 to descend and support the ground. The mounting platform 1 is in an inclined state relative to the horizontal direction, and the connecting part 3511 is in an inclined state relative to the vertical direction. The mounting platform 1 is driven to adjust horizontally by adjusting the connecting part 3511. During this process, the connecting part 3511 is always perpendicular to the mounting platform 1. The connecting part 3511 needs to rotate relative to the matching part 3512, that is, the spherical connector f needs to move in the ball seat 35121, and the configured gap gap can avoid interference between the rod e and the locking part 35122, so that the rod e can swing in any direction around the center of the spherical connector f, that is, the connecting part 3511 can swing in any direction around the center of the spherical connector f relative to the matching part 3512. Since the connection portion 3511 is connected to the mounting platform 1, and the connection portion 3511 can swing in any direction around the center of the spherical connector f relative to the matching portion 3512, the connection portion 3511 drives the mounting platform 1 to move toward the horizontal plane until the plane where the mounting platform 1 is located reaches a horizontal state, thereby achieving the leveling of the mounting platform 1. Figure 12 As shown, the dotted line portion represents the position of the connecting portion 3511 after being offset relative to the matching portion 3512.

[0125] In some non-limiting embodiments, the connecting portion 3511 can be offset in a 360° direction around the mating portion 3512 .

[0126] In some non-limiting embodiments, the setting of the gap can provide a relatively large offset space, and the offset angle between the axis of the locking member 35122 and the axis of the rod e can reach 12 degrees, so as to achieve automatic leveling of terrain with a relatively large slope, so that the drilling device 100 can adapt to a working environment with relatively complex terrain.

[0127] In some embodiments, there may be multiple leveling components 35, and the multiple leveling components 35 cooperate with each other to adjust the position of the mounting platform 1 relative to the ground. Figure 1 In the embodiment shown, a total of four leveling assemblies 35 are provided on the mounting platform 1. It is understood that in practice, the number of leveling assemblies 35 can also be other numbers, which are not illustrated one by one here.

[0128] In some embodiments, each set of the adjustment components 342 is configured with the leveling component 35. For example, referring to Figure 14Each movable assembly 3421 is integrated with a corresponding adjustment assembly 35. In other words, an adjustment assembly 35 is provided at each of the four corners of the plane on which the mounting platform 1 is located. Thus, multiple sets of leveling assemblies 35 can be used to adjust the position of the mounting platform 1 relative to the ground at multiple points, thereby adapting to different slopes and improving the efficiency and flexibility of adjusting the plane on which the mounting platform 1 is located to a horizontal state.

[0129] In some embodiments, reference Figure 15 The drilling device 100 further includes a fine-tuning mechanism 6 disposed on the mounting platform 1 and connected to the drilling tools 2. The fine-tuning mechanism 6 is configured to drive multiple sets of the drilling tools 2 to move synchronously relative to the mounting platform 1 in a first direction (e.g., the y-direction). Thus, by adjusting the fine-tuning mechanism 6, the drilling accuracy of the drilling device 100 can be further improved.

[0130] In some non-limiting embodiments, the fine-tuning mechanism 6 is further configured to drive multiple sets of the drilling tools 2 to move synchronously along the second direction (eg, x-direction) relative to the mounting platform 1 .

[0131] In a typical application scenario, the travel mechanism 31 drives the mounting platform 1 and the multiple sets of drilling tools 2 mounted thereon to the approximate drilling location. The fine-tuning mechanism 6 then fine-tunes the position of the drilling tools 2 in a first direction (e.g., the y-direction). For example, the position of the drilling tools 2 can be determined using GPS positioning. After the fine-tuning of the position of the drilling tools 2 is completed, the drilling tools 2 are controlled to drill.

[0132] As can be seen from the above scheme, multiple sets of drilling tools 2 of the drilling apparatus 100 are installed on the mounting platform 1. Because the fine-adjustment mechanism 6 is installed on the mounting platform 1 and fixedly connected to the drilling tools 2, the fine-adjustment mechanism 6 can drive the drilling tools 2 to move in a first direction (for example, the y-direction) relative to the mounting platform 1. In this way, the position of the drilling tools 2 can be precisely adjusted by the fine-adjustment mechanism 6. By improving the adjustment accuracy of the position of the drilling tools 2, the accuracy of the drilling position can be improved.

[0133] In particular, in the embodiment of the present application, when multiple sets of drilling tools 2 are provided, the fine-tuning mechanism 6 drives the multiple sets of drilling tools 2 to move synchronously relative to the mounting platform 1 in a first direction (e.g., the y-direction). Thus, when multiple holes need to be drilled, the fine-tuning mechanism 6 drives the multiple sets of drilling tools 2 to move synchronously relative to the mounting platform 1 in the first direction (e.g., the y-direction). This allows multiple holes to be drilled simultaneously using the multiple sets of drilling tools 2, while ensuring the accuracy of the distances between adjacent holes.

[0134] In some embodiments, each set of drilling tools 2 can also independently correspond to a fine-tuning mechanism 6, so that the movement of each set of drilling tools 2 in multiple sets of drilling tools 2 can be independently adjusted through their respective corresponding fine-tuning mechanisms 6, which helps to flexibly adjust the movement of each set of drilling tools 2 according to the actual requirements of the distance between adjacent holes, and meet the personalized requirements for the distance between adjacent holes in different application scenarios.

[0135] Further reference Figure 15 The fine-tuning mechanism 6 may include: a connecting rod 61, connected to the drilling tool 2 and movably connected to the mounting platform 1, the extension direction of the connecting rod 61 being parallel to the first direction (for example, the y direction); a driving portion 62, used to drive the connecting rod 61 to move along the first direction (for example, the y direction); wherein the connecting rod 61 is configured to drive the multiple sets of drilling tools 2 to move synchronously relative to the mounting platform 1 along the first direction (for example, the y direction) under the drive of the driving portion 62.

[0136] In some embodiments, there are multiple sets of drilling tools 2 , and the connecting rods 61 connect the multiple sets of drilling tools 2 in series to achieve synchronous movement of the multiple sets of drilling tools 2 relative to the installation platform 1 .

[0137] In some embodiments, the drive unit 62 may be a micro-motor that serves as a power source for the movement of the connecting rod 61 to drive the connecting rod 61 to reciprocate linear motion along a first direction (e.g., the y-direction). The drive unit 62 may convert its own rotational motion into linear motion or directly provide linear motion.

[0138] In some embodiments, adjacent drilling tools 2 are connected by a connecting rod 61 , and the number of the driving part 62 is one and the driving part 62 is provided on the connecting rod 61 between any adjacent drilling tools 2 .

[0139] Further, refer to Figure 17 , the fine-tuning mechanism 6 also includes: a limiting assembly 63. The limiting assembly 63 is connected to the connecting rod 61 and the drilling tool 2, and is used to limit the relative position of the connecting rod 61 and the drilling tool 2 to ensure the fixedness of the relative position of the connecting rod 61 and the drilling tool 2. The limiting assembly 63 can limit the movement of the connecting rod 61 relative to the drilling tool 2 in a first direction (for example, the y direction) to keep the relative position of the connecting rod 61 and the drilling tool 2 accurately fixed. Especially in some typical application scenarios, when there are multiple sets of drilling tools 2, ensuring the fixedness of the relative position of the connecting rod 61 and the drilling tool 2 by the limiting assembly 63 can help the connecting rod 61 to synchronously drive multiple sets of drilling tools 2 to move synchronously along the first direction (for example, the y direction).

[0140] In some embodiments, the limiting assembly 63 includes a pair of limiting clips. The pair of limiting clips are sleeved on the connecting rod 61 and abut against both sides of the drilling tool 2. In other words, the limiting assembly 63 achieves a fixed connection between the connecting rod 61 and the drilling tool 2. Specifically, along a first direction (e.g., the y-direction), the connecting rod 61 passes through the drilling tool 2, and a limiting clip is provided on each side of the drilling tool 2. The limiting clips on both sides of the drilling tool 2 can fix the relative position of the connecting rod 61 and the drilling tool 2, preventing the connecting rod 61 from moving relative to the drilling tool 2 in the first direction (e.g., the y-direction).

[0141] In some non-limiting embodiments, each position-limiting clip can include a first clip and a second clip, which can be connected by fasteners such as bolts. Specifically, the first clip and the second clip are provided with grooves, the shape of which matches the shape of the connecting rod 61. After both the first clip and the second clip are clamped to the connecting rod 61, the first clip and the second clip are fastened together using fasteners to achieve a fixed connection between the position-limiting clip and the connecting rod 61.

[0142] In some embodiments, reference Figure 21 The drilling tool 2 may include: a column 21, a drill rod portion 22, and a lifting mechanism 23. When a position limiting assembly 63 is configured, and the position limiting assembly 63 includes a pair of position limiting clamps, the column 21 is provided with a mounting hole, the connecting rod 61 passes through the mounting hole and penetrates the column 21, and the pair of position limiting clamps are sleeved on the connecting rod 61 and abut against both sides of the column 21 to achieve precise fixation of the relative position of the connecting rod 61 and the drilling tool 2.

[0143] In some embodiments, multiple sets of drilling tools 2 spaced apart along the same direction (e.g., the y-direction) and connected together by cross bars 4 can be referred to as a drilling tool group. Each set of drilling tool groups can independently adjust the movement of its respective drilling tools 2 relative to the mounting platform 1 through the drive unit 62 in its respective fine-tuning mechanism 6. Alternatively, the drive unit 62 in the fine-tuning mechanism 6 of one set of drilling tool groups can be used to adjust the synchronous movement of the drilling tools 2 in all drilling tool groups relative to the mounting platform 1. In this case, the connecting rods 61 in each drilling tool group are connected to achieve the linkage of all drilling tools 2. The drawings of the embodiments of the present application illustrate a set of drilling tool groups, each of which includes four sets of drilling tools 2, and the position adjustment of all drilling tools 2 is achieved through one of the drive units 62. For multiple sets of drilling tool groups or other modified structures, please refer to the illustrations of this embodiment, and they will not be shown one by one here.

[0144] In some embodiments, combined Figure 16 、 Figure 18 as well as Figure 19The drilling device 100 further includes an auxiliary fixing mechanism 7 connected to the drilling tool 2 and to the connecting rod 61 and / or the mounting platform 1, and adapted to follow the movement of the drilling tool 2 relative to the mounting platform 1 in the first direction (e.g., the y-direction). Thus, when the fine-tuning mechanism 6 adjusts the relative position of the drilling tool 2 and the mounting platform 1, the auxiliary fixing mechanism 7 is configured to maintain the stability of the drilling tool 2 as it moves relative to the mounting platform 1.

[0145] Furthermore, the auxiliary fixing mechanism 7 includes a sliding portion 71 , a portion of which is fixedly connected to the drilling tool 2 , and another portion of which is slidably connected to the mounting platform 1 ; and a first pull rod 72 , one end of which is connected to the drilling tool 2 and the other end of which is connected to the sliding portion 71 .

[0146] In some non-limiting embodiments, the sliding portion 71 includes a connecting plate 711 and a sliding member 712. One end of the connecting plate 711 is connected to the drilling tool 2. The sliding member 712 is connected to the connecting plate 711 and is slidably connected to the mounting platform 1. As a result, when the drilling tool 2 moves relative to the mounting platform 1, driven by the connecting rod 61, the sliding portion 71 moves with the drilling tool 2. This maintains the stability of the drilling tool 2 relative to the mounting platform 1 without affecting its movement, thereby preventing the drilling tool 2 from shaking relative to the mounting platform 1.

[0147] In a specific embodiment, the sliding member 712 can have a variety of structural styles. For example, Figure 18 and Figure 19 The sliding member 712 includes a slide groove 7121, and the slide groove 7121 is adapted to the guide rail 7122 on the mounting platform 1. Figure 16 and Figure 26 The sliding member 712 includes a sleeve 7123 provided on the connecting plate 711 and a shaft 7124 provided on the mounting platform 1 , the sleeve 7123 is sleeved on the shaft 7124 , and the axial direction of the shaft 7124 is parallel to the first direction (eg, the y direction).

[0148] Furthermore, in some embodiments, Figure 1 、 Figures 15 to 19The auxiliary fixing mechanism 7 further includes a first tie rod 72. One end of the first tie rod 72 is connected to the drilling tool 2, and the other end is connected to the sliding portion 71. For example, one end of the first tie rod 72 is connected to the column 21. The other end of the first tie rod 72 is connected to the connecting plate 711. The provision of the first tie rod 72 allows a force to be applied to the drilling tool 2 in a direction perpendicular to the first direction (e.g., the y-direction) on the plane of the mounting platform 1, thereby achieving auxiliary fixation of the drilling tool 2 in a direction perpendicular to the first direction (e.g., the y-direction) on the plane of the mounting platform 1, thereby ensuring the stability of the drilling tool 2. Furthermore, a triangular support structure can be formed between the first tie rod 72, the drilling tool 2, and the sliding portion 71 to further enhance the auxiliary fixation effect of the drilling tool 2 and ensure the stability of the drilling tool 2. In some non-limiting embodiments, one end of the first tie rod 72 is rotatably connected to the drilling tool 2, and the other end of the first tie rod 72 is rotatably connected to the sliding portion 71. For example, the rotational connection may be a hinge connection, that is, one end of the first pull rod 72 is hinged to the drilling tool 2, and the other end of the first pull rod 72 is hinged to the sliding portion 71. The two ends of the first pull rod 72 are rotationally connected to the drilling tool 2 and the sliding portion 71, respectively. In this way, a small amount of rotation can occur at the end connection position to prevent stress concentration.

[0149] Furthermore, the auxiliary fixing mechanism 7 may further include: a second pull rod 73 , one end of which is connected to the drilling tool 2 , and the other end of which is connected to the connecting rod 61 .

[0150] In other embodiments, reference Figure 1 and Figure 15 , the auxiliary fixing mechanism 7 may include a second pull rod 73. One end of the second pull rod 73 is connected to the drilling tool 2, and the other end of the second pull rod 73 is connected to the connecting rod 61. For example, one end of the second pull rod 73 is connected to the column 21. By setting the second pull rod 73, a force can be applied to the drilling tool 2 in a first direction (for example, the y direction) to achieve auxiliary fixation of the drilling tool 2 in the first direction (for example, the y direction) and ensure the stability of the drilling tool 2. In addition, a triangular support structure can be formed between the second pull rod 73, the drilling tool 2 and the connecting rod 61 to further improve the auxiliary fixation effect of the drilling tool 2 and ensure the stability of the drilling tool 2.

[0151] In some non-limiting embodiments, one end of the second tie rod 73 is rotatably connected to the drilling tool 2, and the other end of the second tie rod 73 is rotatably connected to the connecting rod 61. For example, the rotatable connection may be a hinged connection, where one end of the second tie rod 73 is hingedly connected to the drilling tool 2, and the other end of the second tie rod 73 is hingedly connected to the connecting rod 61. In other words, the two ends of the second tie rod 73 are rotatably connected to the drilling tool 2 and the connecting rod 61, respectively. As a result, a small amount of rotation can occur at the end connection locations to prevent stress concentration.

[0152] Further reference Figure 1 and Figure 15 The number of drilling tools 2 in the multiple sets of drilling tools 2 is at least two (for example, four), and at least two sets of drilling tools 2 are arranged along the first direction (for example, the y direction), and at least the two sets of drilling tools 2 located on both sides are respectively configured with the second pull rod 73.

[0153] In some embodiments, taking the example of four sets of drilling tools 2 installed on a single mounting platform 1, each drilling tool 2 can be connected to a first tie rod 72, and the two outer drilling tools 2 can also be connected to a second tie rod 73. Thus, for the two outer drilling tools 2 along the spacing arrangement direction (e.g., the y-direction), the first tie rod 72 and the second tie rod 73 work together to ensure the stability of the drilling tools 2. For the two drilling tools 2 in the middle, since their shaking amplitude can be limited to a certain extent by the adjacent drilling tools 2, the second tie rod 73 is preferably omitted. This helps to reduce the size of the mounting platform 1 in the y-direction, making the entire drilling device 100 more compact and flexible.

[0154] In some embodiments, the first and second tie rods 72, 73 are located on different sides of the drilling tool 2. The first and second tie rods 72, 73 extend in different directions. For example, the first and second tie rods 72, 73 are located on different sides of the column 21. This allows for multi-directional auxiliary fixation of the drilling tool 2, further improving its stability.

[0155] It should be understood that the auxiliary fixing mechanism 7 may include only the sliding portion 71, only the second pull rod 73, the sliding portion 71 and the first pull rod 72, the first pull rod 72 and the second pull rod 73, the sliding portion 71 and the second pull rod 73, or the sliding portion 71, the first pull rod 72 and the second pull rod 73. The auxiliary fixing mechanism 7 can improve the fixity of the relative position of the drilling tool 2 and the fine-tuning mechanism 6. In particular, in some scenarios, when the height of the drilling tool 2 is relatively high, the auxiliary fixing mechanism 7 can prevent the bottom of the drilling tool 2 from being deformed when being pulled and moved, thereby ensuring force balance, so that the fine-tuning mechanism 6 can relatively smoothly drive the drilling tool 2 to move relative to the mounting platform 1.

[0156] In some embodiments, combined Figure 22 The drilling mechanism 100 may further include a support structure 9 connected to the mounting platform 1 and located below the connecting rod 61. The support structure 9 is configured to slidably support the connecting rod 61 on the mounting platform 1 and guide the connecting rod 61 to slide relative to the mounting platform 1 along the first direction (e.g., the y-direction). The support structure 9 may be, for example, a roller.

[0157] In some embodiments, combined Figure 1 、 Figure 15 and Figure 21 The drilling tool 2 includes: a column 21, which is vertically installed on the mounting platform 1; a drill rod portion 22, which is movably installed on the column 21; a lifting mechanism 23, which is installed on the column 21 and connected to the drill rod portion 22, and the lifting mechanism 23 is used to drive the drill rod portion 22 to move relative to the column 21 in a third direction (for example, the z direction) perpendicular to the plane of the mounting platform 1.

[0158] Furthermore, the column 21 may include a plurality of sections, and adjacent sections may be connected by fasteners such as bolts, etc. This facilitates transportation and storage of the column 21.

[0159] In some embodiments, the column 21 may be provided with one or more holes 211 (see Figures 16 to 19 The hole 211 provided can reduce the weight of the column 21, thereby reducing the overall weight of the drilling device 100. The hole 211 can be an oblong hole (also called a waist-shaped hole), or a round hole or other suitable type of hole.

[0160] In some embodiments, the drill rod portion 22 is provided with a spiral blade 221 extending around the axial direction of the drill rod portion 22 . The spiral blade 221 rotates to drill into the ground and discharge soil to obtain a hole of a certain depth.

[0161] In some non-limiting embodiments, the spiral blade 221 includes at least two sections, wherein the diameter of the spiral blade farthest from the mounting platform 1 is the largest. In this way, a countersink can be drilled to meet the drilling requirements in a specific application scenario. It is understandable that the diameter of the entire spiral blade 221 can be the same. The diameter of the spiral blade 221 can be set according to the requirements of the actual application scenario. In a specific implementation, the lifting mechanism 23 serves as the power source of the drill rod portion 22, and is used to drive the drill rod portion 22 to move along the z direction toward the ground or away from the ground.

[0162] In some embodiments, continue to refer to Figure 15 and Figure 21 The drilling tool 2 may further include a power head assembly 26. The power head assembly 26 is disposed on the top of the drill rod portion 22. The power head assembly 26 drives the drill rod portion 22 to rotate, and at the same time, the lifting mechanism 23 drives the drill rod portion 22 and the power head assembly 26 to move toward the ground, thereby achieving the drilling function.

[0163] The power head assembly 26 may be connected to the drill rod portion 22 via fasteners such as bolts.

[0164] In some embodiments, reference Figure 21The lifting mechanism 23 may include a lifting motor 231, a chain 232, and a sprocket 233. The sprocket 233 may be a gear. The chain 232 is mounted to the upper and lower ends of the column 21 via the sprocket 233, and the sprocket 233 is mounted to the column 21 via a pin. The chain 232 meshes with the sprocket 233. The chain 232 is connected to the power head assembly 26. The lifting motor 231 is connected to the sprocket 233 to drive the sprocket 233 to rotate. The sprocket 233 and the chain 232 cooperate to drive the power head assembly 26 to move upward or downward toward the ground or away from the ground. The lifting motor 231 can be connected to the column 21, that is, the lifting motor 231 can be set on the column 21.

[0165] Further reference Figure 1 、 Figure 15 and Figure 21 、 Figures 23 to 25 The drilling tool 2 also includes a casing 24 that is sleeved over at least a portion of the drill rod 22. The casing 24 is connected to the lifting mechanism 23 via an automatic locking and unlocking mechanism 25. The automatic locking and unlocking mechanism 25 is configured to automatically unlock the casing 24 and the lifting mechanism 23 as the lifting mechanism 23 drives the casing 24 and the drill rod 22 toward the target surface. As the lifting mechanism 23 drives the drill rod 22 away from the target surface, the casing 24 and the lifting mechanism 23 automatically lock, thereby driving the casing 24 to move synchronously. Thus, during the drilling process, the casing 24 effectively improves drilling accuracy and protects the drilled hole from being backfilled by surrounding loose soil, thereby avoiding the need for repeated drilling and significantly improving drilling efficiency, ensuring both drilling accuracy and hole roundness. Furthermore, the casing 24 and the drill rod 22 share a common lifting mechanism 23, simplifying the structure and reducing costs.

[0166] Specifically, refer to Figures 23 to 25 Casing 24 is sleeved on at least a portion of drill rod portion 22 to prevent drill rod portion 22 from shaking, thereby guaranteed drilling accuracy and roundness. In addition, casing 24 is also used for the soil that is drilled out to be discharged from the upper end opening of casing 24.

[0167] In some embodiments, during drilling operations, the casing 24 is positioned over the drill rod portion 22 in the section adjacent to the target surface and abuts against the target surface. Furthermore, as the spiral blades 221 rotate, soil expelled from the hole moves upward along with the spiral blades 221 to the end of the casing 24 away from the target surface and is expelled from the casing 24, rather than being deposited directly around the opening of the target surface.

[0168] Furthermore, when the drill rod 22 moves to the target point for drilling, the automatic locking and unlocking mechanism 25 always locks the casing 24 and the lifting mechanism 23 together, so that the casing 24 moves with the drill rod 22 without manual handling, saving labor costs.

[0169] Furthermore, when the lifting mechanism 23 drives the drill rod 22 and casing 24 downward to the target surface, the automatic locking and unlocking mechanism 25 automatically unlocks. At this point, the connection between the casing 24 and the lifting mechanism 23 is released, and the casing 24 remains above or in close proximity to the target surface, while the drill rod 22 continues downward to complete the drilling operation. Thus, the automatic locking and unlocking mechanism 25 ensures that the casing 24 does not hinder the further advancement of the drill rod 22 and also prevents damage to the casing 24 due to excessive pressure.

[0170] Furthermore, when the drilling operation is completed and the drill rod 22 and casing 24 need to be lifted (for example, when the drill rod 22 needs to be withdrawn from the drilled hole and the casing 24 needs to be stowed in order to move to the next drilling location to continue the drilling operation), the lifting mechanism 23 will move in the reverse direction. At this time, the automatic locking and unlocking mechanism 25 will automatically lock, and the casing 24 will reconnect with the lifting mechanism 23, allowing the casing 24 to move synchronously with the rise of the lifting mechanism 23, so that the casing 24 can be retrieved.

[0171] Thus, the automatic locking and unlocking mechanism 25 ensures that the sleeve 4 is always mounted on the outer periphery of the drill rod 22, thereby preventing the drill rod 22 from shaking and improving the drilling accuracy and roundness. When the drill rod 22 is recovered after drilling, the casing 24 can also be recovered together with the casing 24, so as to quickly prepare for the next drilling operation.

[0172] In some embodiments, the casing 24 and the drill rod portion 22 share a lifting mechanism 23, simplifying the structure and reducing costs. Moreover, it is precisely because the casing 24 and the drill rod portion 22 share a lifting mechanism 23 that the casing 24 and the drill rod portion 22 can achieve synchronous movement at certain times.

[0173] In some embodiments, the automatic locking and unlocking mechanism 25 can use a sensor distance measurement system. For example, the automatic locking mechanism 5 can control the connection and disconnection between the casing 24 and the lifting mechanism 23 according to the distance to the target surface.

[0174] In some embodiments, continue to refer to Figures 23 to 25The automatic locking and unlocking mechanism 25 includes: a hanging portion 251, which is arranged on the protective tube 24; and a supporting portion 252, which is arranged on the lifting mechanism 23; wherein, the protective tube 24 is hung on the supporting portion 252 through the hanging portion 251 under the action of gravity and moves synchronously with the lifting mechanism 23. As the protective tube 24 moves to the target surface, the hanging portion 251 is separated from the supporting portion 252 under the blocking action of the target surface.

[0175] Specifically, the hanging portion 251 is provided on the casing 24 , and its main function is to cooperate with the supporting portion 252 so that the casing 24 can be stably hung (or connected) on the lifting mechanism 23 under the force of gravity or the push of the lifting mechanism 23 .

[0176] Furthermore, the supporting portion 252 is provided on the lifting mechanism 23 for receiving and supporting the hanging portion 251. The supporting portion 252 can ensure that the weight of the casing 24 is stably carried during the normal operation of the drilling tool 2, and through interaction with the hanging portion 251, the casing 24 and the lifting mechanism 23 can achieve synchronous movement and automatic decoupling.

[0177] In a typical application scenario, during the operation of the drilling tool 2, when the lifting mechanism 23 drives the drill rod portion 22 and the casing 24 to move downward, the casing 24 is tightly hung (or connected) to the supporting portion 252 through the hanging portion 251 under the action of gravity, thereby achieving synchronous movement with the lifting mechanism 23.

[0178] When casing 24 moves downward to the target surface, it is blocked by the target surface and cannot continue to move downward. The lifting mechanism 23 must then drive the drill rod 22 to continue its downward movement to complete the drilling operation. At this point, under the blocking force of the target surface, the connection between the stationary support portion 251 and the supporting portion 252, which continues to move downward as the drill rod 22 moves, is automatically released, ultimately causing them to separate. This separation automatically unlocks the casing 24 from the lifting mechanism 23, allowing the casing 24 to remain above or in close proximity to the target surface while the drill rod 22 continues to move downward to complete the drilling operation.

[0179] In a non-limiting embodiment, the hanging portion 251 includes a hook 2511 extending from the protective tube 24 toward the column 21, and the supporting portion 252 includes a hanging rod 2521 extending from the lifting mechanism 23, and the hook 2511 is used to hook the hanging rod 2521. Therefore, the cooperation between the hook 2511 and the hanging rod 2521 can make the connection (or locking) and separation (or unlocking) between the protective tube 24 and the lifting mechanism 23 smoother.

[0180] In some embodiments, the chain 232 includes a hinge axis 2321 , the supporting portion 252 can reuse the hinge axis 2321 of the chain 232 , and the length of the hinge axis 2321 reused as the supporting portion 252 is greater than the length of other hinge axes 2321 of the chain 232 .

[0181] In some embodiments, reference Figure 20 The drilling device 100 further includes a shock absorbing assembly 8, which cooperates with the lifting mechanism 23 to alleviate the vibration of the drill rod 22 in the axial direction of the drill rod 22. In this way, the drilling accuracy can be improved and the service life of the parts can be extended.

[0182] Furthermore, the shock absorbing assembly 8 includes a horizontal shaft 81 and at least one vertical shaft 82. The horizontal shaft 81 is connected to the lifting mechanism 23. One end of the vertical shaft 82 is connected to the horizontal shaft 81, and the other end is connected to the column 21 via an elastic member 83.

[0183] In some embodiments, a sprocket 233 is sleeved on the transverse shaft 81 to enable the chain 232 to be installed on the upper end of the column 21 .

[0184] In some non-limiting embodiments, the elastic member 83 is located on the top of the column 21 and is sleeved on the vertical shaft 82 .

[0185] In some embodiments, the elastic member 83 may be a spring, elastic rubber or other elastic component. The limiting member 84 may be a locking nut. The vertical shaft 82 is threadedly connected to the locking nut.

[0186] In some embodiments, the shock absorbing assembly 8 further includes a limiter 84. The limiter 84 is connected to the vertical shaft 82 and is located on top of the elastic member 83. The limiter 84 can limit the maximum deformation of the elastic member 83, which is used to provide the maximum vibration amplitude during shock absorption.

[0187] Furthermore, a gasket 85 may be provided between the elastic member 83 and the limiting member 84 .

[0188] In a specific implementation, the rotation directions of adjacent drill tools 2 are opposite. That is, one of the adjacent drill tools 2 rotates in the forward direction, while the other drill tool 2 rotates in the reverse direction. This can offset the vibration caused by the operation of the drill tools 2, thereby improving the drilling accuracy and hole quality.

[0189] In some embodiments, there may be multiple mounting platforms 1 , and the multiple mounting platforms 1 may be detachably connected, thereby facilitating the transportation and assembly of the drilling device 100 .

[0190] For example, two mounting platforms 1 can be Figure 1The posture shown is connected end to end along the x-direction. This allows a greater number of holes to be drilled simultaneously in the same direction.

[0191] For another example, two mounting platforms 1 can be Figure 1 The posture shown is spliced ​​along the y direction. In this way, multiple holes arranged in an array can be drilled simultaneously.

[0192] For another example, the width direction of one mounting platform 1 and the length direction of another mounting platform can be connected in a manner such that a row of holes distributed along the x direction and a row of holes distributed along the y direction can be drilled simultaneously.

[0193] In some embodiments, the number of the motion mechanisms 3 is consistent with the number of the mounting platforms 1. Alternatively, the same motion mechanism 3 is used to drive the synchronous movement of multiple mounting platforms 1. This can further simplify the structure of the drilling device 100 and reduce production and manufacturing costs.

[0194] As described above, the technical solution of the embodiment of this application integrates multiple sets of drilling tools 2 on a single mounting platform 1, achieving synchronized drilling and ensuring the accuracy of multiple hole layouts. Furthermore, the mounting platform 1 is driven in at least one direction by a motion mechanism 3, enabling the mounting platform 1 and the drilling tools 2 supported thereon to be quickly moved to the target drilling location to execute the drilling operation. By operating the drilling apparatus 100 of this embodiment, multiple drilling tools 2 can be operated simultaneously, significantly improving the drilling efficiency of the drilling apparatus 100.

[0195] Furthermore, the position adjustment mechanism 34 includes at least one body 341 and at least one set of adjustment components 342. The at least one set of adjustment components 342 further includes a moving component 3421 and a driving component 3422. The moving component 3421 is movably connected to the body 341 at one end and to the mounting platform 1 at the other end. The driving component 3422 is connected to the moving component 3421 to drive the moving component 3421 to move the mounting platform 1 relative to the body in a second direction (e.g., the x-direction). In this way, not only can the position of the drilling tool 2 be adjusted by driving the drilling device 100 in its own moving direction (for example, the y direction), but the driving component 3422 in the position adjustment mechanism 34 can also drive the moving component 3421 to move, thereby driving the installation platform 1 to move. Since the drilling tool 2 is connected to the installation platform 1, the second direction (for example, the x direction) in the plane where the installation platform 1 is located intersects with the moving direction (for example, the y direction) of the drilling device 100 (for example, the y direction), so as to achieve the adjustment of the position of the drilling tool 2 in the second direction (for example, the x direction), thereby improving the accuracy of the drilling position.

[0196] Furthermore, the leveling assembly 35 includes a lifting assembly 351, one end of which is mounted perpendicular to the mounting platform 1 and the other end is hinged to the moving assembly 3421. The lifting assembly 351 is configured to drive the body 341 to move back and forth in a direction perpendicular to the plane of the mounting platform 1. This facilitates adjusting the angle between the mounting platform 1 and the horizontal plane, thereby maintaining a horizontal position. By adjusting the mounting platform 1 to a horizontal position, the drilling tool 2 can avoid deviation in the drilling position during drilling, further improving drilling position accuracy.

[0197] Furthermore, the drilling device includes a fine adjustment mechanism 6. Since the fine adjustment mechanism 6 is disposed on the mounting platform 1 and fixedly connected to the drilling tool 2, the fine adjustment mechanism 6 can drive the drilling tool 2 to move in a first direction (e.g., the y-direction) relative to the mounting platform 1. Thus, the position of the drilling tool 2 can be precisely adjusted by the fine adjustment mechanism 6. By improving the adjustment accuracy of the position of the drilling tool 2, the accuracy of the drilling position can be improved.

[0198] Furthermore, the auxiliary fixing mechanism 7 is connected to the drilling tool 2 and to the connecting rod 61 and / or the mounting platform 1, and can move relative to the mounting platform 1. The auxiliary fixing mechanism 7 can improve the stability of the drilling tool 2 when moving relative to the mounting platform 1.

[0199] Furthermore, adjacent drilling tools 2 are connected by a cross bar 4, which can maintain the relative positions between adjacent drilling tools 2 and help to further improve the accuracy of the drilling position.
