Description

Technical Field

[0001] This invention relates to the field of geological exploration equipment technology, specifically to a geological exploration straightening device. Background Technology

[0002] In geological exploration operations, especially during deep-hole core drilling, the drill rod and drill bit are prone to radial swaying and deviation during drilling due to factors such as uneven formation hardness, developed rock fractures, or changes in drilling pressure. This swaying not only affects the core recovery rate and sampling quality but also leads to accelerated drill bit wear and even causes accidents inside the borehole. Therefore, drilling equipment is usually equipped with a drill bit straightening device to constrain the movement trajectory of the drill rod and ensure the verticality or designed angle of the borehole.

[0003] Existing drill bit straightening devices typically include a straightening frame installed on the drilling platform or at the borehole opening. The straightening frame is fixed to the ground base at the borehole opening by bolts or hydraulic means. The straightening frame has a straightening ring or clamping mechanism inside. The drill rod passes through the straightening ring, and the swing of the drill rod during drilling is restricted by mechanical contact.

[0004] However, in practical applications, existing ground-fixed centering devices have significant limitations. Because the centering point is only located on the surface, and as drilling depth increases, the drill rod length increases, reducing its rigidity as a slender rod, when the drill bit encounters complex hard rock layers deep underground and generates severe swaying forces, this force is transmitted to the surface centering point through the long drill rod. Since the centering point is too far from the drill bit, the lever arm is too long, significantly weakening the actual constraint force of the centering device on the drill bit. More importantly, the foundation for this centering device is surface soil or rock. When the surface foundation is soft or subjected to vibration, the centering device itself is prone to displacement or swaying, failing to provide stable centering support for deep drill bits. Summary of the Invention

[0005] To address the aforementioned problems, the main objective of this invention is to provide a geological exploration straightening device that can effectively suppress radial oscillation of the drill bit, thereby improving drilling quality and construction safety.

[0006] To achieve the above objectives, the present invention provides a geological exploration straightening device for correcting the position of a geological exploration drill rod. The device includes a support assembly, a first straightening assembly, and a second straightening assembly. The support assembly includes a main support plate and a top support plate, with the top support plate located on the top surface of the main support plate. The first straightening assembly is located on the back side of the main support plate and includes a pusher, a driven gear, a moving platform, a drive member, and a fixing rod. A square groove is provided above the back side of the main support plate. The moving platform is horizontal and movably disposed within the square groove in the vertical direction. The driven gear is rotatably mounted on the moving platform. The pusher drives the moving platform to move, and the drive member drives the driven gear to rotate. The upper end of the fixing rod passes through the moving platform and is fixedly connected to the lower end face of the driven gear. A helical anchor is provided at the lower end of the fixing rod. The second straightening assembly is located in front of the main support plate and is used to limit the position of the geological exploration drill rod.

[0007] Preferably, the square groove is provided with several longitudinally arranged protruding strips, and the inner side of the moving platform is provided with several sliding grooves. The protruding strips are located in their corresponding sliding grooves, and the two ends of the moving platform are movable up and down and locked onto the inner walls of both sides of the square groove.

[0008] Preferably, the lower end of the pusher is provided with a telescopic rod, the lower end of which is connected to the center of the top surface of the driven gear through a bearing, and the output end of the drive member is provided with a driving gear that meshes with the driven gear.

[0009] Preferably, the first straightening component further includes an annular clip, which is fixed to the back of the main support plate by a connecting rod, and the fixing rod is sleeved inside the annular clip.

[0010] Preferably, the support assembly further includes a side support frame and two mounting side plates, the two mounting side plates being vertically mounted on both sides of the front end face of the main support plate, and the side support frame being located below the rear end face of the main support plate.

[0011] Preferably, the side support frame includes a mounting block, a rotating component, a rear baffle, and a base plate. The mounting block is fixed to the back of the main support plate, the rotating component is rotatably connected to the mounting block, one end of the rear baffle is fixedly connected to the rotating component, and the other end is fixedly connected to the top of the base plate. The base plate is provided with several positioning holes.

[0012] Preferably, the second straightening component includes a servo motor, an external threaded rod, a bending plate, and a positioning rod. A connecting plate is provided between the two side support frames, and the external threaded rod is rotatably disposed between the top support plate and the connecting plate.

[0013] Preferably, the servo motor is mounted on the top support plate, and the output end of the servo motor is fixedly connected to the upper end of the external thread rod. The external thread rod is provided with a moving block, and the moving block is fixedly connected to the positioning rod.

[0014] Preferably, the outer end of the positioning rod is provided with a first annular sleeve, the two ends of the bending plate are respectively fixedly connected to the outer end face of the side support frame, and the middle of the bending plate is provided with a second annular sleeve, the second annular sleeve and the first annular sleeve are coaxially arranged.

[0015] Preferably, the geological exploration drill rod is inserted into the first annular sleeve and the second annular sleeve. The first annular sleeve is provided with a fixing screw, which is used to fix the position of the geological exploration drill rod.

[0016] Through the above technical solution, the beneficial effects of the present invention include: the geological exploration straightening device of the present invention is provided with a support component and two straightening components, which are installed on the support component. The second straightening component can fix the geological exploration drill rod, and the first straightening component can fix the support component on the ground and underground, transferring the straightening support point from a traditional single position on the ground to a predetermined position inside the hole near the drill bit. Because the support point significantly shortens the lever arm distance with the working end of the drill bit, it can directly apply a centering constraint force from the source of drill bit sway, effectively overcoming the problem of ground straightening failure caused by the slender drill rod, and achieving high-precision and high-strength straightening of the drill bit, thereby improving the stability of the first straightening component, that is, improving the stability of the geological exploration drill bit.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Please refer to Figures 1 to 6 The present invention provides a geological exploration straightening device for straightening drill rods during geological exploration to suppress their radial sway. It mainly includes a support assembly, and a first straightening assembly and a second straightening assembly installed on the support assembly. The first straightening assembly is used to firmly fix the entire device to the ground and underground borehole, while the second straightening assembly is used to directly clamp and guide the drill rod.

[0027] like Figure 1 and Figure 2 As shown, the support assembly of the present invention includes a main support plate 11, a top support plate 12, two mounting side plates 14, and a side support frame 13. The top support plate 12 is horizontally arranged and fixedly connected to the top of the main support plate 11. The two mounting side plates 14 are parallel, vertical, and fixedly connected to both sides of the front end face of the main support plate 11, forming a space for accommodating and installing the second straightening assembly. The side support frame 13 is arranged below the rear end face of the main support plate 11 and is used to provide auxiliary support for the entire device when the device is working.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the first straightening component of the present invention is located on the back of the main support plate 11. Its main function is to anchor the lower part of the device to the ground. Specifically, the first straightening component includes a pusher 21, a driven gear 22, a moving platform 23, a drive component 24, and a fixing rod 25. A longitudinally extending square groove 111 is provided on the upper part of the back of the main support plate 11. The moving platform 23 is arranged horizontally and can be moved up and down and accommodated in the square groove 111. In order to ensure the smooth movement of the moving platform 23, as a preferred embodiment, several longitudinally arranged protrusions 112 are provided on the inner wall of the square groove 111. In this embodiment, there are two protrusions 112. Correspondingly, several sliding grooves 231 corresponding to the protrusions 112 are provided on the inner side of the moving platform 23. Therefore, in this embodiment, there are also two sliding grooves 231. The protrusions 112 are embedded in the sliding grooves 231, thereby guiding the moving platform 23 to slide up and down along the inner wall of the square groove 111. More preferably, the two ends of the mobile platform 23 are movable up and down and are locked onto the inner walls of the square groove 111. Specifically, the inner ends of the two sides of the mobile platform 23 are provided with protrusions (not shown in the figure), and the inner walls of the two sides of the square groove 111 are provided with strip-shaped grooves. The protrusions are slidably locked into the grooves, thereby further improving the stability of the mobile platform 23 during movement.

[0029] In addition, the driven gear 22 in this invention is rotatably mounted on the moving platform 23. The pushing member 21 can be a hydraulic cylinder or a pneumatic cylinder. The pushing member 21 is fixedly mounted on the top of the main support plate 11 or the top support plate 12. Its lower end is provided with a telescopic rod 211, which can be a piston rod. The lower end of the telescopic rod 211 is connected to the center of the top surface of the driven gear 22 through a bearing 212. This connection method allows the pushing member 21 to drive the moving platform 23 and the driven gear 22 mounted on it to move up and down as a whole, while the driven gear 22 can rotate freely relative to the telescopic rod 211. In other embodiments, the telescopic rod 211 of the pushing member 21 can be directly fixedly connected to the moving platform 23, thereby allowing the pushing member 21 to directly push the moving platform 23 to move.

[0030] Please refer to the accompanying drawings. The driving component 24 of the present invention is fixedly mounted on the mobile platform 23. Its output end is provided with a driving gear 26, which is also rotatably mounted on the mobile platform 23. The driving gear 26 meshes with the driven gear 22. By activating the driving component 24, it drives the driving gear 26 to rotate, thereby driving the driven gear 22 to rotate on the mobile platform 23. In addition, the upper end of the fixing rod 25 passes through the mobile platform 23 and is fixedly connected to the lower end face of the driven gear 22, so that it rotates synchronously with the driven gear 22. The lower end of the fixing rod 25 is provided with a spiral anchor 251, which is a structure similar to a drill bit or ground anchor, used to screw into the ground to provide radial constraint on the slender fixing rod 25 and prevent it from swinging.

[0031] Furthermore, the first straightening component of the present invention is also provided with one or more annular clips 27. The annular clips 27 are fixedly connected to the back of the main support plate 11 via connecting rods 28 and are located below the square groove 111. The fixing rod 25 is slidably sleeved in the annular clips 27. The annular clips 27 can both allow the fixing rod 25 to move up and down and rotate, and can effectively limit its radial displacement, thus ensuring the accuracy of anchoring.

[0032] like Figure 2 , Figure 5 and Figure 6 As shown, the second straightening component of this invention is located in front of the main support plate 11 and is used to define and straighten the geological exploration drill rod. Specifically, the second straightening component of this invention includes a servo motor 31, an external threaded rod 32, a bending plate 33, and a positioning rod 34. A connecting plate 35 is provided between the two mounting side plates 14, with the connecting plate 35 located at a lower position. The external threaded rod 32 is vertically arranged between the top support plate 12 and the connecting plate 35, with its two ends rotatably mounted on the top support plate 12 and the connecting plate 35, respectively. The servo motor 31 of this invention is fixedly mounted on the top support plate 12, and its output end is fixedly connected to the upper end of the external threaded rod 32 for driving the external threaded rod 32 to rotate.

[0033] In addition, the second straightening component of the present invention is also provided with a moving block 36, which is threaded onto the external thread rod 32. When the external thread rod 32 rotates, the moving block 36 will move up and down along it. One end of the positioning rod 34 is fixedly connected to the moving block 36, and the other end extends forward of the device and is fixedly provided with a first annular sleeve 37 at its end. The first annular sleeve 37 is provided with a fixing screw 39. The bending plate 33 in the present invention is generally C-shaped or U-shaped. Its two ends are fixedly connected to the outer end faces of the two mounting side plates 14 respectively. The middle part of the bending plate 33 spans across the front of the drill pipe channel and is fixedly provided with a second annular sleeve 38 here. The second annular sleeve 38 and the first annular sleeve 37 are coaxially arranged to form the straightening channel of the drill pipe. The geological exploration drill pipe passes through the first annular sleeve 37 and the second annular sleeve 38. The fixing screw 39 provided on the first annular sleeve 37 can be used to fix the position of the drill pipe. That is, tightening the fixing screw 39 can lock the drill pipe.

[0034] Furthermore, such as Figure 1 and Figure 2As shown, the side support frame 13 of this invention consists of a mounting block 131, a rotating component 132, a rear baffle 133, and a base plate 134. The mounting block 131 is fixed to the back of the main support plate 11. The rotating component 132 is rotatably connected to the mounting block 131. The rotating component 132 can be a hinge-like structure or a hinge. One end of the rear baffle 133 is fixedly connected to the rotating component 132, and the other end is fixedly connected to the top of the horizontally set base plate 134. The base plate 134 is provided with multiple positioning holes 135 for fixing the base plate 134 to the ground with fixing components such as ground nails. This rotatable structural design of the present invention allows the side support frame 13 to be folded up when not in use, facilitating transportation and storage. When in use, it is unfolded, which not only enhances the stability of the device on the ground but also provides temporary support.

[0035] The working process and principle of the present invention will be described in detail below with reference to the accompanying drawings: Before conducting geological exploration drilling operations, the straightening device of the present invention is first transported to the drilling location. According to the site terrain, the side support frame 13 is unfolded, and the base plate 134 is firmly fixed to the ground by installing ground nails or other fasteners in the positioning hole 135, thus achieving the initial positioning of the device.

[0036] Then, according to the preset drill rod alignment depth, the pusher 21 is activated. The pusher 21 pushes the moving platform 23 downward along the square groove 111 via the telescopic rod 211. The sliding of the moving platform 23 is guided by the protruding strip 112 and the slide groove 231, and the movement is smooth and precise. The downward movement of the moving platform 23 causes the fixed rod 25 and the spiral anchor 251 at its end to descend together until the tip of the spiral anchor 251 touches the ground.

[0037] Subsequently, the drive unit 24 is activated, which drives the driven gear 22 to rotate via the driving gear 26. The driven gear 22 drives the fixed rod 25 and the spiral anchor 251 to rotate. Under the combined action of rotation and downward pressure, the spiral anchor 251 is screwed into the ground like a self-tapping screw, reaching the predetermined depth. At this point, the entire device is not only fixed to the ground surface by the side support frame 13, but also obtains strong anchoring force from the underground rock and soil layer through the spiral anchor 251 that penetrates deep underground, achieving dual fixation on the ground and underground, greatly improving the device's anti-overturning and anti-disturbance capabilities.

[0038] Then, the geological exploration drill rod passes through the second annular sleeve 38 and the first annular sleeve 37 in sequence. In this embodiment, there are two bending plates 33 and two annular sleeves 38, located above and below the first annular sleeve 37, respectively. Therefore, the drill rod passes through the first second annular sleeve 38, the first annular sleeve 37, and the second second annular sleeve 38 from top to bottom. Then, the drill rod is temporarily fixed in the first annular sleeve 37 by tightening the fixing screw 39. The servo motor 31 is started, and the servo motor 31 drives the external thread rod 32 to rotate, causing the moving block 36 to move the positioning rod 34 and the first annular sleeve 37 to a predetermined height. When the drilling rig starts working, the fixing screw 39 is loosened, allowing the drill rod to be flexibly positioned in the first annular sleeve 37. The first annular sleeve 37 and the second annular sleeve 38 together constrain the drill rod, effectively limiting the radial swing of the drill rod.

[0039] In summary, the present invention achieves deep anchoring of the device itself through the first straightening component and precise and stable straightening of the drill rod through the second straightening component, effectively solving the technical problem of unstable drill bit straightening caused by only fixing on the ground in the prior art, and significantly improving the quality and safety of geological exploration boreholes.

[0040] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
