Description

Technical Field

[0001] This utility model relates to the field of fixing frame technology, and in particular to a fixing structure for drilling rods in rock and soil exploration. Background Technology

[0002] According to a drill rod fixing structure disclosed in Chinese Publication No. CN223136050U, this drill rod fixing structure, through the setting of a control component, when the drill rod rotates, the turntable and support block fixed on the surface of the drill rod will synchronously perform circular motion. When the support block moves, it will abut against the tangential surface of the slide rod. When the slide rod is under force, the movable block fixed on the surface of the slide rod will synchronously slide on the surface of the liquid storage frame. The horizontal bar fixed on the surface of the movable block will move laterally within the vertical plate under the support of the spring. When the movable block moves, the through hole opened on the surface of the movable block will fit with the circular hole, so the lubricating oil in the liquid storage frame can flow out and fall into the guide frame and enter the arc plate. Then, the ball bearings can attach the lubricating oil to the connection between the drill rod and the fixing plate when the drill rod rotates. The lubricating oil helps to absorb and buffer the vibration and impact energy during the working process, reduce the instantaneous strong impact on the connection, and reduce the possibility of fatigue damage leading to breakage.

[0003] The aforementioned technologies and existing fixed structures are integrally welded and assembled, and cannot be effectively disassembled or folded for storage. This results in them occupying a large space when not in use. Furthermore, due to their large size and weight, multiple people are required to handle and transport them on-site, and they cannot be easily transported by conventional vehicles or carrying tools, making them unsuitable for surveying tasks that require frequent relocation of construction sites. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing fixed structures, which are integrally welded or assembled, have a large volume and cannot be folded, resulting in large space occupation, high weight, and the need for multiple people to cooperate in handling and transportation, making them inconvenient for frequent site relocation. Therefore, a new fixed structure for rock and soil exploration drill rods is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a drilling rod fixing structure for rock and soil exploration, including a fixing frame, with storage grooves on both sides of the fixing frame, two fixing shafts on the surface of each of the two storage grooves, mounting grooves on the top of each of the four fixing shafts, magnets inside the four mounting grooves, legs on one side of each of the four fixing shafts, diagonal rods on the top of each of the four legs, a base plate at one end of each of the four legs, through holes on the top surface of each of the four base plates, ground nails inside the four through holes, a top frame on the top of the fixing frame, a servo motor on the top of the top frame, a spindle at the bottom of the servo motor, guide grooves on both sides of the inner walls of the fixing frame, a moving block at the bottom of the top frame, guide blocks on both sides of the moving block, a mounting frame between the two guide blocks, a DC motor on the top of the mounting frame, and a drilling rod body at the bottom of the DC motor.

[0006] Preferably, both of the storage slots are provided with the bottom end of a fixing frame, the fixing frame is U-shaped, the two fixing shafts on the surface of the two storage slots are parallel, and the fixing shafts are provided with the bottom end of the storage slots, and all four fixing shafts are welded to the fixing frame.

[0007] Preferably, the mounting slots at the top of the four fixed shafts are all located on the surface of the storage slot, and the mounting slots are all perpendicular to the fixed shafts. The magnets inside the mounting slots are all bonded to the fixing frame.

[0008] Preferably, the legs on one side of the four fixed axes are all connected to the fixed axes, and the base plates are all located at the ends of the legs away from the fixed axes, and the base plates are all integrally formed with the legs.

[0009] Preferably, one end of each of the four diagonal braces at the top of the tripod is bolted to the tripod, and the other end of each diagonal brace is bolted to the fixing frame.

[0010] Preferably, the top frame is installed on the top surface of the fixed frame and bolted to the fixed frame. The servo motor is installed in the middle position on the top surface of the top frame and bolted to the top frame. The top end of the spindle passes through the top frame and is splined to the servo motor. The bottom end of the spindle passes through the moving block and is shaft-connected to the fixed frame.

[0011] Preferably, the guide blocks on both sides of the movable block are integrally formed with the movable block, and the guide blocks are installed in the guide grooves on both sides of the inner wall of the fixed frame. The guide blocks and guide grooves are V-shaped. The mounting frame is set on the surface of the movable block and is integrally formed with the movable block. The DC motor is installed on the top surface of the mounting frame and is bolted to the mounting frame. The top end of the drill rod body is splined to the DC motor.

[0012] Beneficial effects

[0013] In this invention, during use, the operator first rotates the two legs stored in the storage slots on both sides of the fixed frame outwards along the fixed axis until they are in contact with the ground. The outer bottom of the two legs is provided with a flat base plate, ensuring stable contact with the ground. Simultaneously, diagonal braces are installed between the main body of the fixed frame and the two legs, with each end of the brace connected to the legs and the fixed frame via pins, forming a stable triangular support structure. After the legs are unfolded and fixed in place, ground nails are driven into the ground through the through holes in the base plate of the legs, achieving a firm anchoring of the entire fixed frame to the ground and improving its resistance to tipping and vibration. When disassembly and storage are required, the operator simply pulls out the ground nails, then pulls out the pins used to fix the ends of the diagonal braces, removing the braces from between the legs and the fixed frame. After removal, the triangular support structure is released. Subsequently, the legs are rotated inwards and folded along the rotation axis, gradually retracting and completely rotating into the storage slots on both sides of the fixed frame. The inner wall of the storage slot is equipped with magnets embedded in the mounting slot. After the legs are folded into the storage slot, they can be attracted and fixed by the magnets to prevent accidental unfolding during transportation. Through the above structural design, the legs can form a stable triangular mechanical support structure in the use state, and completely fit against both sides of the fixed frame in the storage state, making the entire fixed frame present a flat structure, significantly reducing the volume and space occupied. This facilitates single-person handling, storage, and transportation by conventional vehicles, effectively solving the disadvantages of fixed structures that are integrally welded or assembled, large in size, non-foldable, resulting in large space occupation, high weight, and the need for multiple people to cooperate in handling and transportation, making it inconvenient for frequent relocation.

The fixed frame 1 is U-shaped, and the two fixed shafts 3 on the surface of the two storage slots 2 are parallel and at the bottom of the storage slots 2. All four fixed shafts 3 are welded to the fixed frame 1, and the mounting grooves 16 on the top of the four fixed shafts 3 are provided with... The mounting slots 16 are all perpendicular to the fixed shafts 3 and stand on the surface of the storage slot 2. The magnets 17 inside the mounting slots 16 are all bonded to the fixed frame 1. The four legs 7 on one side of the fixed shafts 3 are all axially connected to the fixed shafts 3. The base plates 13 are all located at the ends of the legs 7 away from the fixed shafts 3 and are integrally formed with the legs 7. One end of the diagonal rods 8 at the top of the four legs 7 is bolted to the legs 7 and the other end of the diagonal rods 8 is bolted to the fixed frame 1. The top frame 4 is installed on the top surface of the fixed frame 1 and is bolted to the fixed frame 1. The servo motor 5 is installed in the middle of the top surface of the top frame 4 and is bolted to the top frame 4. The top end of the spindle 6 passes through the top frame 4 and is splinedly connected to the servo motor 5. The bottom end of the spindle 6 passes through the moving block 10 and is axially connected to the fixed frame 1. The guide blocks 11 on both sides of the moving block 10 are integrally formed with the moving block 10. The guide blocks 11 are installed in the guide grooves 9 on both sides of the inner wall of the fixed frame 1. The guide blocks 11 and the guide grooves 9 are both V-shaped. The mounting frame 12 is set on the surface of the moving block 10 and is integrally formed with the moving block 10. The DC motor 18 is installed on the top surface of the mounting frame 12 and is bolted to the mounting frame 12. The top end of the drill rod body 19 is splinedly connected to the DC motor 18.

[0024] The fixing frame 1 in this application is an integral U-shaped frame structure. Both outer surfaces of the frame are provided with storage slots 2 for storing the legs 7. Two fixing shafts 3 are arranged in parallel along the horizontal direction on the surface of each storage slot 2. The four fixing shafts 3 are welded to the bottom inner wall of the storage slot 2, serving as the rotation hinge shafts of the legs 7. The top of the four fixing shafts 3 is provided with mounting slots 16 along the vertical direction. The mounting slots 16 are arranged perpendicular to the fixing shafts 3. The four mounting slots 16 are embedded with magnets 17 made of permanent magnets. The magnets 17 are firmly bonded to the fixing frame 1 with structural adhesive, which is used to attract and fix the legs 7 to the inner wall of the storage slot 2 after storage and folding to prevent accidental unfolding. Each fixed shaft 3 is rotatably connected to a leg 7 on one side. The leg 7 is a steel tubular structure, with a flat base plate 13 integrally formed at the end away from the fixed shaft 3 for large-area contact with the ground to enhance support stability. Each base plate 13 has a through hole 14 vertically penetrating its top surface, into which a ground nail 15 can be inserted to anchor the bottom of the leg 7 to the ground. The choice of ground nail 15 can be made according to the terrain. Each leg 7 is bolted to a diagonal rod 8 at its upper end. The diagonal rod 8 is a detachable rod structure, and its other end is bolted to the side wall of the fixed frame 1. The leg 7, diagonal rod 8, and fixed frame 1 form a triangular support structure. The triangular force-bearing structure can effectively withstand the vertical load and eccentric lateral force from the drill pipe during operation, preventing the fixed frame 1 from tipping over. A top frame 4 is installed on the top of the fixed frame 1. The top frame 4 is fixedly connected to the top surface of the fixed frame 1 by bolts. A servo motor 5 is installed in the middle of the top of the top frame 4 by bolts. The output end of the servo motor 5 is splinedly connected to the spindle 6. The upper end of the spindle 6 passes through the top frame 4 and meshes with the spline of the output shaft of the servo motor 5. The lower end passes through the middle of the fixed frame 1 and rotates with the fixed frame 1. The spindle 6 can achieve forward and reverse rotation output under the drive of the servo motor 5. The inner walls of both sides of the fixed frame 1 are provided with V-shaped guide grooves 9 in the vertical direction. Guide blocks 11 are installed in the guide grooves 9. The two guide blocks 11 are integrally formed with the moving block 10. The moving block 10 slides up and down along the guide grooves 9. With the cooperation of the guide blocks 11 and the V-shaped guide grooves 9, precise linear guidance can be achieved and shaking can be avoided. The top surface of the moving block 10 is integrally formed with a mounting frame 12. The top surface of the mounting frame 12 is bolted with a DC motor 18. The output shaft of the DC motor 18 is meshed with the upper end of the drill rod body 19 through a spline, so that the DC motor 18 can drive the drill rod body 19 to rotate at high speed to realize drilling operation. The servo motor 5 drives the spindle 6 to rotate, which can drive the moving block 10 to move up and down along the guide grooves 9, thereby realizing the lifting and lowering control of the drill rod body 19. During the drilling operation, the servo motor 5 provides axial thrust, and the DC motor 18 provides rotational torque. The two work together to complete the vertical drilling operation of the drill rod.In actual use, the operator first rotates the legs 7, which are folded and stored in the storage slots 2 on both sides of the fixed frame 1, outwards along their respective fixed axes 3, so that the legs 7 are rotated out of the storage slots 2 to the position in contact with the ground. Then, the upper end of each leg 7 is connected to the corresponding diagonal bar 8 with bolts, and the other end of the diagonal bar 8 is fixed to the side wall of the fixed frame 1 with bolts. The four sets of legs 7, together with the fixed frame 1 and the diagonal bars 8, form four stable triangular support units, which constitute a spatial four-legged support frame, greatly improving the overall stability of the fixed frame 1. Then, the ground nails 15 are passed through the through holes 14 on the bottom plate 13 of each leg 7 and nailed into the ground to firmly anchor the legs 7 to the ground to resist the vibration and counter torque generated during the drilling process, so that the fixed frame 1 is stably erected. After the support structure is erected, the operator starts the servo motor 5 and DC motor 18 on the top frame 4. The servo motor 5 drives the spindle 6 to rotate, which in turn drives the moving block 10 to move up and down along the guide groove 9, thereby achieving the axial advancement of the drill rod body 19. At the same time, the DC motor 18 drives the drill rod body 19 to rotate at high speed, performing drilling and sampling operations on the lower strata. During the operation, the V-shaped surface cooperation between the guide groove 9 and the guide block 11 ensures that the lifting and lowering movements of the moving block 10 and the drill rod body 19 are smooth and without swaying, preventing the drill rod from deflecting. The four sets of triangular support legs 7 resist the radial swaying force and torque reaction force from the drilling process, maintaining the verticality and overall stability of the drill rod body 19. When the drilling operation is completed and dismantling and storage are required, the operator first pulls the four ground nails 15 out of the ground to release the bottom anchorage, then removes the bolts at both ends of the diagonal rod 8 in sequence, removes the diagonal rod 8 from between the leg 7 and the fixed frame 1, and releases the triangular support structure. Then, the leg 7 is rotated and folded inward along the rotation axis of each leg 7, so that the leg 7 is flipped and folded in sequence and completely rotated into the storage slots 2 on both sides of the fixed frame 1. After the leg 7 is folded and stored, its outer surface will be magnetically attracted and fixed by the magnet 17 in the mounting slot 16 on the inner wall of the storage slot 2, thereby preventing it from popping out on its own due to vibration during transportation. Finally, the entire fixed frame 1 is stored as a flat structure, which is small in size and easy for a single person to carry, store and transport by conventional vehicles. Specific Implementation Example 2:

[0026] Reference Figure 1-4A drilling rod fixing structure for geotechnical exploration is further based on the basic structure in Specific Embodiment 1. Before operation, the operator first flips and unfolds the legs 7 stored in the storage slots 2 on both sides of the fixing frame 1 outward along the fixing axis 3, so that the bottom plate 13 of the legs 7 makes large-area contact with the ground to form initial support. Then, the upper end of each leg 7 is connected to the diagonal bar 8 with bolts. The other end of the diagonal bar 8 is connected to the side wall of the fixing frame 1 with bolts, thereby forming a stable triangular mechanical support unit. This triangular support structure can decompose and transfer the vertical load, vibration impact force and eccentric lateral force generated by the drill rod to the ground, so that the fixing frame 1 remains stable and does not tilt during operation. Then, the operator anchors the ground nails 15 through the through holes 14 on the bottom plate 13 of the legs 7 to the ground, so that the entire support system is firmly fixed to the ground, further enhancing its anti-tilting and anti-vibration capabilities. After the support is fixed, the operator starts the servo motor 5 installed on the top frame 4 and the DC motor 18 on the mounting frame 12 through the external control device. The output shaft of the servo motor 5 is connected to the upper spline of the spindle 6 through a spline. The spline connection allows the rotational torque of the servo motor 5 to be transmitted to the spindle 6 without slippage. The lower end of the spindle 6 passes through the middle of the fixed frame 1 and rotates with the fixed frame 1 in a bearing-type structure, so that the spindle 6 can achieve stable forward and reverse rotation under the drive of the servo motor 5. The rotation of the spindle 6 drives the moving block 10 installed on it to move up and down along the V-shaped guide grooves 9 on both sides of the fixed frame 1 through the thread. The cooperation between the V-shaped guide groove 9 and the guide block 11 on the moving block 10 ensures the precise linear guidance of the moving block 10 and the drill rod body 19 installed on it during the lifting process and avoids shaking. Thus, the servo motor 5 applies a controllable axial thrust to the drill rod body 19 through the spindle 6. Meanwhile, the DC motor 18, mounted on the moving block 10, is fixed to the top surface of the mounting bracket 12 by bolts. Its output shaft is also connected to the upper spline of the drill pipe body 19 via a spline. This spline connection structure can ensure efficient torque transmission while avoiding slippage, allowing the high-speed rotational power of the DC motor 18 to be directly transmitted to the drill pipe body 19, driving the drill pipe body 19 to rotate at high speed to cut the underlying formation. During drilling, the servo motor 5 drives the spindle 6 to rotate slowly and propel the moving block 10 downward, providing a continuous axial feed force to the drill pipe body 19. The DC motor 18 provides high-speed rotational torque. The two work together to enable the drill pipe body 19 to complete the vertical drilling operation of the formation under the action of stable axial thrust and continuous rotational cutting force. Throughout the process, the fit between the V-shaped guide groove 9 and the guide block 11 ensures that the movement trajectory of the drill rod body 19 remains vertical and accurate, avoiding drill rod swaying due to lateral shaking; the four sets of triangular support units composed of the legs 7, the diagonal rods 8 and the fixed frame 1 effectively absorb and disperse the radial impact force and counter-torque generated during drilling, keeping the fixed frame 1 stable as a whole.After the operation is completed, turn off the motor and remove the ground nails 15 and diagonal rods 8. Rotate and fold the stand 7 inward along the fixed axis 3 and retract it into the storage slot 2. After the stand 7 is folded, it is attracted and fixed by the magnets 17 in the mounting slot 16, thus storing the entire mounting frame 1 into a flat structure for easy transportation and redeployment. It should be noted that the DC motor 18 and servo motor 5 of this device are powered by external power or mains power via cables, and are controlled by a position control device and operated by an operator.

[0027] In summary:

[0028] 1. When using the device, the operator first rotates the two legs 7 stored in the storage slots 2 on both sides of the fixed frame 1 outwards along the fixed axis 3 until they are in contact with the ground. The bottom of the outer end of the two legs 7 is provided with a flat base plate 13, which can stably contact the ground. At the same time, diagonal rods 8 are installed between the main body of the fixed frame 1 and the two legs 7. The two ends of the diagonal rods 8 are connected to the legs 7 and the fixed frame 1 by pins, so that the main body of the fixed frame 1, the legs 7 and the diagonal rods 8 form a stable triangular support structure. After the legs 7 are unfolded and fixed in place, ground nails 15 are driven into the ground through the through holes 14 on the base plate 13 of the legs 7, so as to achieve a firm anchoring of the entire fixed frame 1 to the ground and improve the anti-tipping and anti-vibration ability. When disassembly and storage are required, the operator simply needs to pull the ground nails 15 out of the ground, then pull out the pins used to fix the two ends of the diagonal rod 8 in sequence, and remove the diagonal rod 8 from between the leg 7 and the fixing frame 1. After removal, the triangular support structure can be released. Subsequently, the leg 7 is rotated and folded inward along the rotation axis of the leg 7, so that the leg 7 gradually retracts and completely rotates into the storage slots 2 provided on both sides of the fixing frame 1. The inner wall of the storage slot 2 is provided with magnets 17 embedded in the mounting slot 16. After the leg 7 is folded into the storage slot 2, it can be attracted and fixed by the magnets 17 to prevent accidental unfolding during transportation. Through the above structural design, the tripod 7 can form a stable triangular mechanical support structure in the use state, while in the storage state it is completely attached to both sides of the fixed frame 1, making the entire fixed frame 1 present as a flat structure, which significantly reduces the volume and space occupied, making it easy for a single person to carry, store and transport by conventional vehicles. It effectively solves the shortcomings of the fixed structure being integrally welded or assembled, which is large in size and cannot be folded, resulting in large space occupation, high weight, and the need for multiple people to cooperate in handling and transportation, making it inconvenient for frequent relocation.
