Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a drilling rig for geological engineering exploration. Background Art

[0002] Geological exploration is extremely important. It's a crucial tool for humanity to understand the Earth's internal structure and resource distribution. Through systematic exploration, we can accurately locate various mineral resources, providing an indispensable material foundation for energy development and industrial production, and meeting society's ongoing demand for metals, energy, and other resources. In engineering construction, geological exploration can identify the geological conditions of the construction area, such as stratum stability and groundwater conditions, in advance, effectively mitigating geological disaster risks and ensuring the safe and smooth construction of major infrastructure such as bridges, tunnels, and high-rise buildings. Furthermore, exploration of areas prone to geological disasters helps us gain a deeper understanding of disaster mechanisms, establish early warning systems, and minimize loss of life and property. It plays an irreplaceable role in safeguarding the human living environment and promoting sustainable economic and social development.

[0035] See Figure 1 、 Figure 2and Figure 3 , Figure 1 、 Figure 2 and Figure 3 The figure shows a structural diagram of a geological engineering exploration drilling rig in one embodiment of the present application. The present application provides a geological engineering exploration drilling rig in one embodiment, comprising: a mobile frame 1 and a drilling mechanism 3;

[0036] The mobile frame 1 is provided with a drilling drive mechanism 2, which includes a drilling drive assembly 21 and a lifting assembly 22. The output end of the lifting assembly 22 is in transmission connection with the drilling drive assembly 21 so that the drilling drive assembly 21 can be lifted and lowered along the direction of gravity.

[0037] The drilling mechanism 3 includes a drilling tube 31 and multiple extension tubes 32. The drilling tube 31 includes a first tube wall 311 and a second tube wall 312. The first tube wall 311 and the second tube wall 312 are pivotally connected via a first pivot axis 313. A first fixing member 3111 is provided on a side of the first tube wall 311 away from the first pivot axis 313. A first fixing groove is provided on a side of the second tube wall 312 away from the first pivot axis 313. The first fixing groove extends axially along the first pivot axis 313. The first fixing member 3111 is detachably engaged with the first fixing groove. A drilling head 314 is provided at one end of the drilling tube 31, and a first connecting tube head 315 is provided at the other end.

[0038] The extension tube 32 includes a third tube wall 321 and a fourth tube wall 322, which are pivotally connected via a second pivot axis 323. A second fixing member 3211 is provided on the side of the third tube wall 321 away from the second pivot axis 323, and a second fixing groove 3221 is provided on the side of the fourth tube wall 322 away from the second pivot axis 323. The second fixing groove 3221 extends axially along the second pivot axis 323, and the second fixing member 3211 and the second fixing groove 3221 are detachably engaged. A second connecting tube head 324 is provided at one end of the extension tube 32, and a third connecting tube head 325 is provided at the other end of the extension tube 32.

[0039] The first connecting pipe head 315 and the second connecting pipe head 324 are detachably adapted; the second connecting pipe head 324 of one of the two extension pipes 32 is detachably connected to the third connecting pipe head 325 of the other;

[0040] The output end of the drilling drive assembly 21 is connected to the first connecting pipe head 315 or the third connecting pipe head 325 driven by the drilling mechanism 3, so that the drilling mechanism 3 can perform a drilling action on the exploration bottom surface.

[0041] Specifically, the lifting assembly 22 of the drilling drive mechanism 2 on the mobile frame 1 can control the drilling drive assembly 21 to rise and fall along the direction of gravity, thereby flexibly adjusting the drilling height and depth to adapt to various exploration scenarios. The drilling pipe 31 of the drilling mechanism 3 is pivoted by the first pipe wall 311 and the second pipe wall 312 via a first pivot axis 313. The first fixing member 3111 of the first pipe wall 311 and the first fixing groove of the second pipe wall 312 are detachably matched, and the first fixing groove extends axially along the first pivot axis 313. This design not only facilitates the opening and closing operation of the drilling pipe 31, but also facilitates the convenient opening of the pipe wall to remove samples from the pipe after the exploration is completed. The drilling head 314 at one end of the drilling pipe 31 is responsible for the drilling operation, and the first connecting pipe head 315 at the other end can be adapted to be connected to the second connecting head of the extension pipe. The third tube wall 321 and the fourth tube wall 322 of the extension tube 32 are pivotally connected by a second pivot shaft 323. The second fixing member 3211 of the third tube wall 321 and the second fixing groove 3221 of the fourth tube wall 322 are also detachably matched. The second connecting pipe head 324 at one end of the extension tube 32 and the third connecting pipe head 325 at the other end can be connected to each other, thereby achieving flexible assembly of the extension tube 32 and expanding the drilling depth. The output end of the drilling drive assembly 21 is connected to the first connecting pipe head 315 of the drilling tube 31 or the third connecting pipe head 325 of the extension tube 32, driving the drilling mechanism 3 to drill the exploration ground. After drilling is completed, the various connecting components can be easily separated and the tube wall opened, allowing the geological sample in the tube to be relatively completely removed, greatly reducing damage and loss of the sample, providing reliable guarantees for subsequent accurate geological analysis, and significantly improving the quality and efficiency of geological exploration work.

[0042] The specific operation process of the device is as follows: after the mobile frame 1 moves to the target exploration position, the first connecting pipe head 315 of the drilling pipe 31 is connected to the output end of the drilling drive assembly 21, and the lifting assembly 22 lifts the drilling drive assembly 21 to a suitable height along the gravity direction, so that the drilling head 314 of the drilling pipe 31 performs a drilling operation on the target ground. When the drilling pipe 31 is about to be completely drilled into the ground, the first connecting pipe head 315 of the drilling pipe 31 is disassembled from the drilling drive assembly 21, and the second connecting pipe head 324 of the extension pipe 32 is connected to the first connecting pipe head 315 of the drilling pipe 31, and the extension pipe 32 is connected. The third connecting pipe head 325 of the extension pipe 32 is connected to the output end of the drilling drive assembly 21, so that the drilling rig can continue to explore and sample deep underground. After all exploration tasks are completed, it is only necessary to pull the extension pipe 32 and the drilling pipe 31 out of the ground in turn, and open the extension pipe 32 and the drilling pipe 31 through the second fixing piece 3211, the second fixing groove 3221, the second pivot shaft 323, the first fixing piece 3111, the first fixing groove and the first pivot shaft 313 to take out the geological samples in the pipe, which solves the problem of sampling difficulty of existing related devices and achieves the purpose of saving manpower, time and improving efficiency.

[0043] The device pivots the first tube wall 311 and the second tube wall 312 along the first pivot axis 313, and has a detachable first fixing member 3111 and a first fixing groove on the corresponding side, so that the drilling tube 31 can be used to extract geological samples; the third tube wall 321 and the fourth tube wall 322 are pivoted by the second pivot axis 323, and have a detachable second fixing member 3211 and a second fixing groove 3221 extending axially and correspondingly, so that the extension tube 32 can be used to extract samples, thereby solving the problems of difficulty in sampling in the sampling tube and easy damage to the sample during the sampling process in related devices, thereby saving manpower and time and improving work efficiency.

[0044] The device features a first connecting pipe head 315 at one end of a drilling tube 31, and second and third connecting pipe heads 324 and 325 at each end of an extension tube 32. The first and second connecting pipe heads 315 and 324 are easily removable and adaptable, and the second connecting pipe head 324 of one extension tube 32 can be easily removably connected to the third connecting pipe head 325 of the other extension tube 32. This effectively resolves the problem of related devices often requiring multiple small-volume sampling, resulting in a cumbersome and inefficient sampling process. Furthermore, the outer diameter of the extension tube 32 is the same as that of the drilling tube 31.

[0045] Specifically, during geological exploration, when the extension tube 32 is connected to increase the drilling depth, the consistent outer diameter ensures the stability and balance of the entire drilling mechanism 3 during drilling. Changes in tube diameter do not create additional resistance or uneven force on the drill rod, thereby reducing the risk of bending, deformation, or even breakage of the drill rod during drilling, ensuring smooth drilling operations. Furthermore, the consistent outer diameter ensures a consistent appearance of the drilling mechanism 3, making installation, disassembly, and transportation more convenient and facilitating unified operation and management by operators.

[0046] Furthermore, the first connecting pipe head 315 and the second connecting pipe head 324 are threadedly connected; and the second connecting pipe head 324 of one of the two extension pipes 32 is threadedly connected to the third connecting pipe head 325 of the other.

[0047] Specifically, threaded connections feature a simple structure and reliable connection. In the complex environment of geological exploration, they ensure a tight connection between the various components of the drilling mechanism 3, effectively preventing loosening or disconnection caused by external forces such as vibration and torsion during the drilling process, thereby ensuring the continuity and stability of the drilling operation. Furthermore, threaded connections facilitate installation and disassembly. When the combination of the drilling tube 31 and the extension tube 32 needs to be replaced or adjusted, the operator can simply connect or disconnect them with a simple rotation. This convenient and efficient operation saves time and manpower, while also improving the flexibility and adaptability of the entire exploration equipment, facilitating the requirements of geological exploration at varying depths.

[0048] Furthermore, the first fixing groove is provided with a plurality of first threaded holes, and the plurality of first threaded holes are distributed at intervals along the extension direction of the first fixing groove;

[0049] The first fixing member 3111 is engaged with the first fixing groove, and the first fixing member 3111 is provided with a plurality of light holes corresponding to the plurality of first threaded holes;

[0050] Each first threaded hole is threadedly connected with a first screw.

[0051] Specifically, the cooperation of multiple first threaded holes and light holes can realize the fastening connection between the first fixing piece 3111 and the first fixing groove, so that the opening and closing state of the drilling pipe 31 can be flexibly adjusted according to actual needs, that is, after the geological exploration sampling is completed, the geological samples with relatively complete geology can be easily taken out.

[0052] Furthermore, the second fixing groove 3221 is provided with a plurality of second threaded holes 3222 , and the plurality of second threaded holes 3222 are distributed at intervals along the extending direction of the second fixing groove 3221 ;

[0053] The second fixing member 3211 is engaged with the second fixing groove 3221 , and the second fixing member 3211 is provided with a plurality of light holes corresponding to the plurality of second threaded holes 3222 ;

[0054] Each second threaded hole 3222 is threadedly connected with a second screw.

[0055] Specifically, the cooperation of multiple second threaded holes 3222 and second light holes 3212 can realize the fastening connection between the first fixing piece 3111 and the first fixing groove, so that the opening and closing state of the extension tube 32 can be flexibly adjusted according to actual needs, that is, after the geological exploration sampling is completed, the geological samples with relatively complete geology can be easily taken out.

[0056] Furthermore, the drilling drive assembly 21 includes a drive motor 211 and a rotating drive rod 212, the output end of the drive motor 211 is transmission-connected to one end of the rotating drive rod 212, and the other end of the rotating drive rod 212 is detachably connected to the first connecting pipe head 315 or the third connecting pipe head 325.

[0057] Specifically, the drive motor 211, serving as a power source, provides stable and powerful driving force for the drilling operation. Its output drives the rotary drive rod 212 to rotate at high speed, thereby initiating rotation of the connected drilling mechanism 3, thereby achieving drilling operations on the exploration surface. The detachable connection between the rotary drive rod 212 and the connecting pipe head greatly enhances the flexibility and convenience of the device. During actual exploration operations, when it is necessary to extend the sampling depth, the connecting pipe head and the rotary drive rod 212 can be quickly separated and reassembled.

[0058] Furthermore, the lifting assembly 22 includes a main rod 221 and a moving rod 222. The main rod 221 is connected to the moving frame 1. The main rod 221 and the moving rod 222 are telescopically connected. The end of the moving rod 222 away from the main rod 221 is fixedly connected to a lifting frame 2221. The lifting frame 2221 is fixedly connected to the drive motor 211 to support the drive motor 211.

[0059] Specifically, a lifting frame 2221 is fixed to the end of the mobile rod 222 away from the main rod 221, and the lifting frame 2221 is fixedly connected to the drive motor 211, thereby supporting the drive motor 211. During the geological exploration process, this structure can easily adjust the height position of the drilling drive assembly 21. When drilling is required at exploration points of different depths or heights, the drilling drive assembly 21 and the drilling mechanism 3 connected thereto can be accurately raised and lowered to the appropriate operating height by telescoping the main rod 221 and the mobile rod 222, which is suitable for the complex and changeable exploration site terrain and different drilling depth requirements. This not only ensures the accuracy and effectiveness of the drilling operation, but also improves the adaptability and operational convenience of the entire drilling rig in different operating environments, reduces the time and manpower consumption caused by the inconvenience of height adjustment, and further improves the efficiency of geological exploration work. Among them, the lifting assembly 22 can be an electric push rod, a linear motor, a lifting cylinder, etc.

[0060] Furthermore, the main rod 221 is covered with a guide sleeve 2211 , the guide sleeve 2211 is slidably connected to the main rod 221 , and the guide sleeve 2211 is fixedly connected to the housing of the driving motor 211 .

[0061] Specifically, the guide sleeve 2211 plays a key role in guiding and supporting the lifting assembly 22 during its lifting operation. When the movable rod 222 extends and retracts relative to the main rod 221, thereby driving the drive motor 211 to move up and down, the guide sleeve 2211 ensures that the drive motor 211 moves smoothly along the axis of the main rod 221, preventing the drive motor 211 from deflecting or shaking during the lifting process, thereby ensuring the stability and accuracy of the drilling drive assembly 21 during the lifting process.

[0062] Furthermore, a plurality of wheel frames 11 are provided on the mobile frame 1, and wheels 111 are pivotally connected to the wheel frames 11. The wheel frames 11 are pivotally connected to the mobile frame 1 through a third pivot shaft so that the wheel frames 11 can rotate around the axis of the third pivot shaft to be retracted off the ground or lowered to the ground.

[0063] Specifically, when the drilling rig needs to be fixed in one position for drilling operations, the wheel frame 11 can be folded up to lift the wheel 111 off the ground, ensuring the stability of the drilling rig during operation and avoiding the movement or shaking of the wheel 111 affecting the drilling operation; and when the drilling rig needs to be moved to different exploration locations, the wheel frame 11 can be lowered to let the wheel 111 grounded, thereby realizing convenient transportation and flexible movement of the drilling rig, greatly improving the adaptability and operability of the device in different working conditions, and providing more convenience and efficiency for geological engineering exploration operations.

[0064] Furthermore, a plurality of evenly distributed anchor members 12 are provided on the mobile frame 1, and the anchor members 12 are pivotally connected to the mobile frame 1 through a fourth pivot shaft 121 so that the anchor members 12 can rotate along the axis of the fourth pivot shaft 121 to be folded or lowered, and a plurality of anchor rod holes 122 are provided on the anchor member 12, and the anchor rod holes 122 are used for passing the anchor rods.

[0065] Specifically, during geological exploration operations, when the drilling rig reaches the designated location and is ready to begin drilling, the anchor member 12 can be used to pass the anchor rod through the anchor hole and drive it into the ground. In this way, the frame is firmly fixed to the ground, effectively enhancing the stability of the drilling rig during operation, preventing it from being displaced or shaken due to factors such as vibration and reaction force generated by the drilling rig, and ensuring that the drilling operation can be carried out accurately and smoothly. When the drilling rig needs to be moved, the anchor rod can be easily removed and the anchor member 12 can be stowed for smooth transfer of the drilling rig.
