Description

Technical Field

[0001] This invention relates to the field of drilling rig technology, specifically a portable folding exploration drilling rig main body device. Background Technology

[0002] Geological exploration is a fundamental step in mineral resource development, engineering construction, and scientific research. Traditional exploration drilling rigs are usually large and heavy, relying on large vehicles for transportation, making it difficult to access remote mountainous areas or rugged terrain.

[0003] Although some portable drilling rigs have appeared on the market, existing portable drilling rigs are limited by size and weight, often adopting a single-stage telescopic or directly fixed structure, and most of them have the problem of limited drilling stroke, which affects the normal progress of exploration work. Therefore, in view of the above situation, there is an urgent need to provide a portable folding exploration drilling rig main body device to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a portable, foldable exploration drilling rig main body device, which aims to solve the problems mentioned in the background art.

[0005] This invention is implemented as follows: a portable, foldable exploration drilling rig main body device, comprising:

[0006] The housing is a square frame structure, and a multi-functional side plate is hinged to the side of the housing. A working hole is provided at the bottom of the housing.

[0007] The housing includes a storage assembly and a drilling assembly. The storage assembly controls the multi-functional side panel switch while allowing the end of the drilling assembly to enter and exit the housing through the working hole.

[0008] The drilling assembly includes a multi-stage telescopic component, which is disposed on the housing assembly, and the end of the multi-stage telescopic component is provided with a drilling component. The housing assembly is provided with a drive component for driving the drilling component to work.

[0021] The first-stage telescopic tube is slidably installed on the guide rod 2, and the top of the first-stage telescopic tube has an internal thread hole that is threaded to connect with the first-stage threaded tube.

[0022] As a further aspect of the present invention: the secondary telescopic unit includes:

[0023] The secondary telescopic pipe is located inside the primary telescopic pipe. A limit block is fixedly installed on the top of the secondary telescopic pipe, and a strip groove that is slidably connected to the limit block is opened on the side wall of the primary telescopic pipe.

[0024] The secondary threaded pipe is rotatably installed inside the primary telescopic pipe. The secondary threaded pipe can move along the length of the primary telescopic pipe. The top of the secondary telescopic pipe is provided with an internal threaded hole that is threadedly connected to the secondary threaded pipe.

[0025] And transmission components, used to realize the power transmission between the primary threaded pipe and the secondary threaded pipe.

[0026] As a further aspect of the present invention: the transmission component includes a drive gear fixedly installed at the bottom of the primary threaded tube, and multiple sets of strip-shaped internal tooth grooves are equally spaced on the inner wall of the secondary threaded tube. The multiple sets of strip-shaped internal tooth grooves are combined to form an internal tooth ring structure that can mesh with the drive gear, and the drive gear and the strip-shaped internal tooth grooves can slide relative to each other in the length direction of the primary threaded tube, so that the primary threaded tube can always drive the secondary threaded tube to rotate during the movement of the secondary threaded tube following the primary telescopic tube.

[0027] As a further aspect of the present invention: the drilling assembly includes a drill bit and a locking buckle.

[0028] As a further aspect of the present invention: the driving component includes:

[0029] The support frame is fixedly mounted on the support plate;

One end of the telescopic drive shaft is fixedly installed with a drive block, and the other end of the telescopic drive shaft is rotatably installed on a support frame. The top of the drill bit has a groove that engages with the drive block.

[0031] And a drive motor for rotating the telescopic transmission shaft, the drive motor being mounted on a support frame.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] 1. Existing portable drilling rigs, limited by size and weight, often employ single-stage telescopic or directly fixed structures, resulting in limited drilling depth (stroke) and difficulty in meeting the needs of deep-hole exploration under complex geological conditions. This invention innovatively designs a multi-stage telescopic assembly comprising a primary telescopic unit and a secondary telescopic unit. The primary threaded tube drives the primary telescopic tube for the first stage of extension, while simultaneously utilizing the meshing transmission mechanism of the drive gear and the internal toothed groove to synchronously drive the secondary threaded tube to rotate during the first stage of extension, thereby driving the secondary telescopic tube for the second stage of extension. This nested, two-stage telescopic structure allows the device to remain compact in its stored state, while in operation, it can release an effective working stroke far exceeding its own height. Without increasing the overall transport volume of the equipment, it significantly expands the operating depth range of the drill bit, effectively solving the technical pain points of traditional portable drilling rigs—short stroke and inability to adapt to deep exploration.

[0034] 2. This invention cleverly couples the opening and closing actions of the storage assembly and the multi-functional side panel through a mechanical linkage mechanism. Specifically, the lifting and lowering movement of the support plate on the guide rod not only controls the entry and exit of the drilling assembly, but also directly drives the multi-functional side panel to rotate around the hinge point through the linkage rod.

[0035] Storage state: When the support plate moves up, the linkage rod pulls the multi-functional side plate to fold inward and fit tightly against the shell, forming a closed box structure, which greatly reduces the space occupied and makes it easy for a single person to carry or for vehicle transportation. It is especially suitable for working environments with inconvenient transportation, such as deep mountains and dense forests.

[0036] Operating state: When the support plate moves downward, the linkage pushes the multi-functional side plate outward. The unfolded side plate not only increases the bottom support area of ​​the equipment, improving overall stability during operation and preventing machine swaying during drilling, but also allows the portable holes on the side plate to be converted into fixed holes. Workers can securely lock the device to the ground using ropes or ground stakes, further enhancing its anti-tipping capability. This "one-action, two-function" design simplifies the operation process and improves the efficiency of field operations.

[0037] 3. The entire device adopts a modular design, highly integrating drive, transmission, telescopic, and drilling functions within the housing. The drive motor and telescopic transmission shaft are coaxially arranged, resulting in a short power transmission path and minimal energy loss. The primary and secondary telescopic tubes utilize a nested sleeve structure, maximizing internal space utilization. Furthermore, the drill bit is secured to the bottom of the secondary telescopic tube with a locking mechanism, facilitating easy disassembly and quick replacement of different drill bit specifications based on geological hardness. When internal components require maintenance, simply reverse the knob to retract the assembly into the housing for repair, eliminating the need for large disassembly tools and reducing maintenance costs and complexity.

[0038] 4. In the power transmission process of the two-stage telescopic movement, this invention employs a unique gear-rack (internal gear ring) sliding meshing technology. The drive gear is fixed to the bottom of the primary threaded tube, while the inner wall of the secondary threaded tube has a strip-shaped internal tooth groove. This design allows the drive gear to slide freely axially within the strip-shaped internal tooth groove while driving the secondary threaded tube to rotate. This means that regardless of the position extended by the primary telescopic tube, power can be continuously and stably transmitted to the secondary mechanism without power interruption or jamming. Simultaneously, the characteristics of the threaded transmission ensure the smoothness and self-locking of the telescopic movement. When the drive stops, the drill bit position remains fixed and will not retract due to gravity or reaction force, thus ensuring the verticality and accuracy of the drilling operation.

[0039] 5. This device is not only suitable for geological and mineral resource exploration, but can also be widely used in various fields such as foundation testing for building engineering, environmental monitoring sampling, and forestry soil analysis. Its high-strength, square-frame shell structure effectively protects internal precision components from outdoor impacts, dust, and water damage. The rationally designed working hole ensures smooth drill rod entry and exit while also providing dust protection when not in use. The overall design fully considers adaptability to harsh outdoor environments and has extremely high potential for widespread application. Attached Figure Description

[0057] The present invention will be further explained below with reference to specific embodiments.

[0058] Please see Figures 1-12 The present invention provides a portable foldable exploration drilling rig main body device, comprising:

[0059] The housing 1 has a square frame structure and a multi-functional side plate 2 is hinged to the side of the housing 1. The bottom of the housing 1 has a working hole 25.

[0060] The housing assembly and the drilling assembly are located inside the housing 1. The housing assembly is used to control the switch of the multi-functional side plate 2 while allowing the end of the drilling assembly to enter and exit the housing 1 through the working hole 25.

[0061] The drilling assembly includes a multi-stage telescopic component, which is disposed on the housing assembly, and the end of the multi-stage telescopic component is provided with a drilling component. The housing assembly is provided with a drive component for driving the drilling component to work.

[0062] In an embodiment of the present invention, the housing 1 and the two multi-functional side plates 2 form a storage box, which facilitates the folding and storage of the drilling assembly and makes it easy to carry. The storage assembly can open the multi-functional side plates 2 by rotating them at the hinge point between the housing 1 and the multi-functional side plates 2, and at the same time, push the drilling assembly out through the working hole 25 to facilitate drilling operations. The drilling assembly can be drilled in the exploration area by using the drive component to drive the drilling assembly to rotate. The open multi-functional side plates 2 make it easy for workers to fix the device. When it needs to be folded and stored, the storage assembly can be used to drive the multi-functional side plates 2 and the drilling assembly to return to their original positions, which effectively improves the convenience of the device.

[0063] In one embodiment of the present invention, please refer to Figures 1-12 The storage assembly includes:

[0064] A guide rod 10 is fixedly installed inside the housing 1. A support plate 7 is slidably installed on the guide rod 10, and both ends of the support plate 7 are in sliding contact with the inner wall of the housing 1.

[0065] The threaded rod 8 is rotatably installed inside the housing 1. The support plate 7 has an internal threaded hole for threaded connection with the threaded rod 8, and the end of the threaded rod 8 extends to the outside of the housing 1.

[0066] and knob 3, which is fixedly installed on the threaded rod 8;

[0067] The storage assembly also includes:

[0068] Support base 5, wherein multiple sets of support base 5 are fixedly installed on each multifunctional side plate 2;

[0069] And a linkage rod 11, one end of which is rotatably connected to the support plate 7, and the other end of which is rotatably connected to the support base 5;

[0070] The multifunctional side plate 2 is also provided with multiple portable holes 4, which facilitates transportation and also makes it easier for staff to fix the device when drilling.

[0071] In this embodiment, the operator can easily rotate the storage threaded rod 8 using the knob 3. The rotating storage threaded rod 8 can drive the support plate 7 to move along the length of the guide rod 10, thereby driving the drilling assembly to rise and fall. During the rising and falling movement of the support plate 7, the linkage rod 11 can drive the multi-functional side plate 2 to rotate around the hinge, realizing the opening and closing of the multi-functional side plate 2. When the support plate 7 moves down, the support plate 7 can drive the linkage rod 11 to push the multi-functional side plate 2 open. At this time, the multi-functional side plate 2 unfolds outward. The portable hole 4 opened on the multi-functional side plate 2 makes it easy for the operator to hold and fix it. When the support plate 7 moves up, the linkage rod 11 will pull the multi-functional side plate 2 back to its original position. At the same time, the drilling assembly moves into the housing 1 for easy storage, effectively improving the portability of the device.

[0072] In one embodiment of the present invention, please refer to Figures 1-12 The multi-stage telescopic assembly includes a primary telescopic unit disposed on the storage assembly, and the primary telescopic unit is provided with a secondary telescopic unit for directly driving the end of the drilling unit to rise and fall.

[0073] The primary telescopic unit includes:

[0074] A primary threaded tube 18 is rotatably mounted on a support plate 7. The support plate 7 is provided with a drive assembly for driving the primary threaded tube 18 to rotate. The drive assembly consists of a motor and a reduction mechanism, which are not specifically limited here.

[0075] Guide rod 2 14, which is fixedly installed on the support plate 7, and multiple sets of guide rod 2 14 are arranged around the primary threaded tube 18;

[0076] The first-stage telescopic tube 9 is slidably installed on the guide rod 14, and the top of the first-stage telescopic tube 9 is provided with an internal thread hole that is threadedly connected to the first-stage threaded tube 18.

[0077] The secondary telescopic unit includes:

[0078] A secondary telescopic pipe 15 is located inside the primary telescopic pipe 9. A limiting block 21 is fixedly installed on the top of the secondary telescopic pipe 15, and a strip groove that is slidably connected to the limiting block 21 is provided on the side wall of the primary telescopic pipe 9.

[0079] The secondary threaded pipe 22, which is rotatably installed inside the primary telescopic pipe 9, can move along the length direction of the primary threaded pipe 18 with the primary telescopic pipe 9, and the top of the secondary telescopic pipe 15 is provided with an internal threaded hole that is threadedly connected to the secondary threaded pipe 22.

[0080] And transmission components, used to realize power transmission between the primary threaded pipe 18 and the secondary threaded pipe 22;

[0081] The transmission component includes a drive gear 24 fixedly installed at the bottom of the primary threaded tube 18. Multiple sets of strip-shaped internal toothed grooves 20 are equally spaced on the inner wall of the secondary threaded tube 22. The multiple sets of strip-shaped internal toothed grooves 20 are combined to form an internal toothed ring structure that can mesh with the drive gear 24. The drive gear 24 and the strip-shaped internal toothed grooves 20 can slide relative to each other in the length direction of the primary threaded tube 18, so that the primary threaded tube 18 can always drive the secondary threaded tube 22 to rotate as the secondary threaded tube 22 moves with the primary telescopic tube 9.

[0082] The drilling assembly includes a drill bit 16 and a locking buckle 19. The drill bit 16 is rotatably mounted on the bottom of the secondary telescopic tube 15 via the locking buckle 19, and the drill bit 16 can move along the secondary telescopic tube 15 in the length direction of the primary threaded tube 18.

[0083] The driving component includes:

[0084] Support frame 13, which is fixedly installed on support plate 7;

[0085] A telescopic drive shaft 17 is rotatably installed inside the primary threaded tube 18. One end of the telescopic drive shaft 17 is fixedly installed with a drive block 23, and the other end of the telescopic drive shaft 17 is rotatably installed on the support frame 13. The top of the drill bit 16 has a groove that engages with the drive block 23. The drive block 23 has a polygonal structure, and the shape of the groove matches the shape of the drive block 23, so that the primary threaded tube 18 can drive the drill bit 16 to rotate.

[0086] And a drive motor 12 for rotating the telescopic transmission shaft 17, the drive motor 12 being mounted on the support frame 13.

[0087] In this embodiment, the drive motor 12 drives the telescopic transmission shaft 17 to rotate, which in turn drives the drill bit 16 to rotate via the transmission block 23 for drilling. The drive assembly drives the primary threaded tube 18 to rotate, which in turn drives the primary telescopic tube 9 to move along the primary telescopic tube 9, achieving primary telescopic movement. The drive gear 24 meshes with the strip-shaped internal tooth groove 20, which in turn drives the secondary threaded tube 22 to rotate via the primary threaded tube 18. When the secondary threaded tube 22 rotates, it drives the secondary telescopic tube 15 to slide within the primary telescopic tube 9, achieving secondary telescopic movement. The two telescopic movements allow for adjustment of the working position of the drill bit 16, extending the working stroke of the drill bit 16 without increasing the overall length of the device, effectively solving the problem of limited stroke in existing portable drilling machines.

[0088] In summary, the working principle of this invention is as follows:

[0089] 1. Initial storage state

[0090] In its non-operating state, the device is in a fully retracted configuration. At this time, the support plate 7 is located at its highest point inside the housing 1, tightly against the inner top wall of the housing. The linkage rod 11 is in a retracted state, pulling the multi-functional side plates 2 on both sides to fit tightly against the sides of the housing 1, forming a single rectangular box for easy transport. The primary telescopic tube 9 and the secondary telescopic tube 15 are fully retracted, and the drill bit 16 is stored inside the housing 1, not protruding from the bottom working hole 25. The telescopic drive shaft 17 is in a compressed or natural length state, and the transmission block 23 remains connected to the groove at the top of the drill bit 16 without relative displacement.

[0091] 2. Device Deployment and Positioning Process

[0092] Upon arrival at the exploration site, the staff first transported the device to the designated location through port 4. Then, they began unfolding the storage assembly.

[0093] Step 1: The worker rotates the knob 3 located outside the housing 1. The knob 3 causes the threaded rod 8 to rotate inside the housing 1.

[0094] Step 2: Since the support plate 7 has an internal threaded hole that mates with the threaded rod 8, and the rotational freedom of the support plate 7 is restricted by the guide rod 10, the rotational motion of the threaded rod 8 is converted into a linear motion of the support plate 7 downward along the axis of the guide rod 10.

[0095] Step 3: As the support plate 7 moves downward, the linkage rods 11 fixed at both ends of it move downward accordingly. The other end of the linkage rod 11 is rotatably connected to the support seat 5 fixed on the multi-functional side plate 2. According to the principle of a four-bar linkage, the downward pushing force of the linkage rod 11 forces the multi-functional side plate 2 to flip outward and open around its hinge point with the housing 1.

[0096] Step 4: When the support plate 7 descends to the predetermined working position, the multi-functional side plate 2 fully unfolds and contacts the ground, forming a stable support base. Workers can use tools to secure the side plate to the ground through the portable hole 4 to prevent displacement during operation. Simultaneously, the entire drilling assembly mounted on the support plate 7 also descends, and the drill bit 16 passes through the working hole 25 at the bottom of the housing 1, making initial contact with or approaching the ground to be drilled.

[0097] 3. Multi-stage telescopic drilling process

[0098] After the device is deployed and secured, the drive assembly and multi-stage telescopic assembly are activated to perform drilling operations:

[0099] Drill bit rotation drive:

[0100] The drive motor 12, mounted on the support frame 13, is started. The output shaft of the drive motor 12 drives the telescopic transmission shaft 17 to rotate. The telescopic transmission shaft 17 passes through the center of the primary threaded tube 18, and its bottom transmission block 23 (usually a polygonal structure, such as a hexagonal head) is embedded in the matching groove on the top of the drill bit 16. Therefore, the rotational power of the drive motor 12 is transmitted to the drill bit 16 sequentially through the telescopic transmission shaft 17 and the transmission block 23, driving the drill bit 16 to rotate at high speed and begin cutting the rock and soil. Because the telescopic transmission shaft 17 has a telescopic function, it can adapt to the axial distance change caused by the subsequent change in the length of the telescopic tube, ensuring continuous power transmission.

[0101] First-stage telescopic feed:

[0102] The drive assembly controlling the first-stage telescopic movement is activated, causing the first-stage threaded tube 18 to rotate. The first-stage telescopic tube 9 is threadedly connected to the first-stage threaded tube 18 through its internal threaded hole at the top, and the outer side of the first-stage telescopic tube 9 is limited by the guide rod 14, preventing it from rotating with the first-stage threaded tube 18. Therefore, the rotation of the first-stage threaded tube 18 drives the first-stage telescopic tube 9 to move downwards in a straight line along the guide rod 14. At this time, the first-stage telescopic tube 9 drives all its internal components (including the second-stage telescopic unit and the drill bit) to extend downwards as a whole, completing the drilling to the first stage depth.

[0103] Two-stage synchronous telescopic feed:

[0104] As the primary telescopic tube 9 extends downwards, the secondary telescopic action occurs simultaneously; this is the core innovation of this invention.

[0105] Power transmission: The drive gear 24, which is fixed at the bottom of the primary threaded tube 18, rotates together with the primary threaded tube 18.

[0106] Meshing transmission: The drive gear 24 meshes with the strip-shaped internal toothed groove 20 located on the inner wall of the secondary threaded tube 22. Although the secondary threaded tube 22 moves downward with the primary telescopic tube 9, the drive gear 24 can slide freely within the groove because the strip-shaped internal toothed groove 20 is a long groove structure that runs through the axial direction, thus maintaining the meshing state at all times. Therefore, the rotational power of the primary threaded tube 18 is transmitted to the secondary threaded tube 22 in real time, driving its rotation.

[0107] Secondary extension: The secondary telescopic tube 15 is located inside the primary telescopic tube 9. The limiting block 21 at its top is engaged in the strip groove on the side wall of the primary telescopic tube 9, restricting the rotational freedom of the secondary telescopic tube 15. When the secondary threaded tube 22 rotates, it drives the secondary telescopic tube 15 to move downward linearly relative to the primary telescopic tube 9 through thread engagement with the top of the secondary telescopic tube 15.

[0108] Superimposed effect: At this point, the total downward displacement of drill bit 16 is equal to the downward displacement of the first-stage telescopic pipe 9 plus the extension of the second-stage telescopic pipe 15 relative to the first-stage pipe. This double superimposed effect allows the drill bit to operate at twice the speed or depth of a single-stage telescopic pipe, greatly improving drilling efficiency and working stroke.

[0109] 4. Dynamic adjustments during the operation process

[0110] During drilling, if hard rock formations are encountered and the torque needs to be increased or the rotation speed adjusted, the parameters of the drive motor 12 can be adjusted through the control system. If drilling needs to be paused but the hole depth needs to be maintained, due to the self-locking characteristic of the threaded drive (especially when the lead angle is large or when in conjunction with a brake), after the primary threaded tube 18 and the secondary threaded tube 22 stop rotating, the primary telescopic tube 9 and the secondary telescopic tube 15 will be firmly locked at the current height, preventing the drill bit 16 from sliding down due to gravity or being pushed up by the reaction force of the rock, thus ensuring operational safety.

[0111] 5. Finishing work and putting things back in their original positions

[0112] Once the borehole reaches the predetermined depth or sampling is completed, a reset operation is performed:

[0113] Step 1: Stop the drive motor 12 and the first-stage telescopic drive assembly, and the drill bit 16 stops rotating and feeding.

[0114] Step 2: Rotate knob 3 in the opposite direction to reverse the direction of the threaded rod 8.

[0115] Step 3: The support plate 7 rises upward along the guide rod 10. During this process:

[0116] Drilling assembly retraction: The upward movement of the support plate 7 causes the primary telescopic tube 9 and the internal secondary telescopic tube 15 to retract upward as a whole. In a typical design, gravity or reverse driving force will cause the secondary telescopic tube to retract into the primary tube first, then the primary tube will retract into the housing, and finally the drill bit 16 will completely enter the housing 1 and leave the ground.

[0117] Side panel folding: As the support plate 7 moves upward, the linkage rod 11 is pulled upward, which in turn pulls the support seat 5, forcing the multi-functional side plate 2 to flip inward around the hinge point until it completely fits the side of the housing 1.

[0118] Step 4: When the support plate 7 returns to its initial highest point, the device returns to its compact, box-like storage state. At this point, the portable port 4 can be lifted for transfer, preparing for the next task.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
