Description

Technical Field

[0001] This invention relates to the field of geological survey and sampling technology, and in particular to a geological survey equipment. Background Technology

[0002] With the advancement of industrialization, especially the booming development of mining, construction and transportation infrastructure, the demand for geological information is constantly increasing, and the exploitation and utilization of underground resources is becoming more and more urgent. The exploration of mineral resources, the investigation of groundwater resources and the construction of various underground projects require scientific and efficient sampling techniques. Therefore, the development of equipment that can effectively obtain geological samples and gain a deeper understanding of underground layered structures has become an important topic in the fields of geology and engineering.

[0003] A search revealed a Chinese patent application, CN214471899U, which discloses a geological exploration sampling device. The device includes handles and an outer frame. Handles are located at both ends of the outer frame, and both handles are fitted with anti-slip sleeves. A switch is located at the upper end of the anti-slip sleeve on the left handle, and a rotating shaft is located at the lower end of the anti-slip sleeve. An oil volume control valve is located at the lower end of the rotating shaft. This device utilizes a valve located at the lower end of the water inlet of existing geological exploration sampling devices. However, the sampling tube in this device, like ordinary sampling tubes, relies entirely on threaded connections for connection. This connection method is not only difficult to disassemble after prolonged tightening, but also prone to disengagement during tube removal due to the close thread spacing.

[0004] To address the issue that sampling tubes relying entirely on threaded connections are prone to being difficult to disassemble later and easily detached during tube removal, we propose a novel geological surveying device. Summary of the Invention

[0005] To overcome the above-mentioned shortcomings in the prior art, the present invention aims to provide a geological surveying device that is easy to connect and prevents detachment during pipe pulling.

[0006] This invention provides a geological exploration equipment, including a drive module, a support frame, and a drill rod module. The drill rod module includes a splicing pipe and a drill bit pipe of the same diameter. A drill bit ring is welded and fixed to the bottom end of the drill bit pipe. The top ends of the drill bit pipe and the splicing pipe have annular grooves of the same size on their inner circumferences, and each annular groove has a threaded groove on its inner circumference. The bottom end of the splicing pipe has a threaded pipe with a wall thickness smaller than that of the splicing pipe. The threaded pipe and the threaded groove form a threaded connection. The drill bit pipe and the splicing pipe... The outer circumference of the pipe is provided with identical strip grooves near the top, and the extension direction of the strip grooves is parallel to the axis of the splicing pipe. The top of the strip grooves extends to the middle of the threaded groove. The top and bottom of the strip grooves are provided with through holes that communicate with the interior. The threaded pipe is provided with a positioning pin hole coaxial with the through hole. A locking mechanism is slidably connected in the strip groove. The locking mechanism includes a slide bar. The top of the slide bar is reserved with a protrusion that can be inserted into both the through hole and the positioning pin hole.

[0007] Furthermore, the inner circumference of the drill bit tube is provided with a plurality of centrally symmetrically distributed embedded grooves near the bottom end, and the inner circumference of the drill bit ring is provided with anti-disengagement protrusions that are adapted to the embedded grooves near the top end. The anti-disengagement protrusions are in an inverted "L" shape.

[0008] Furthermore, the inner walls of the opposite sides of the strip groove are respectively provided with side grooves, and the openings of the two side grooves are opposite to each other and consistent with the extension direction of the strip groove. The two sides of the slider rod away from the convex post are respectively reserved with coaxial convex shafts, and the two convex shafts are slidably connected in the two side grooves. The end of the slider rod near the convex post and on the same side as the convex shaft is provided with a through block rotating hole, and a strip block is rotatably connected in the block rotating hole. The height of the block rotating hole is adapted to the groove width of the side groove, and the strip block can rotate freely in the block rotating hole. When the strip block rotates to a horizontal state, its two ends are just inserted into the side grooves on both sides. At this time, the slider rod is fixed in the strip groove to prevent the convex post inserted into the positioning pin hole and the through hole from falling off during the drilling process.

[0009] Furthermore, the slider rod has an adjusting screw hole on the side away from the protrusion that communicates with the rotating hole of the abutment, and the center line of the adjusting screw hole coincides with the center line of the rotating hole of the abutment. The strip-shaped abutment has a square hole on the side near the adjusting screw hole, and an internal hexagonal stud is screwed into the adjusting screw hole. The end of the internal hexagonal stud near the strip-shaped abutment has a square strip that matches the square hole. When the strip-shaped abutment needs to be rotated, the internal hexagonal stud only needs to be screwed on.

[0010] Furthermore, a marking hole is provided at the end of the internal hexagonal stud away from the strip-shaped abutment, and the position of the marking hole is consistent with the pointing direction of the strip-shaped abutment. Through the marking hole, the state of the strip-shaped abutment in the abutment hole can be known, and locking and unlocking can be completed more quickly.

[0011] Furthermore, the outer circumferential wall of the splicing pipe is provided with a pointing tip at one end near the threaded pipe, and the pointing tip is located directly above the positioning pin hole. The position of the positioning pin hole can be quickly determined by the pointing tip, so that the positioning pin hole and the through hole can be aligned more quickly when assembling and connecting the drill rod module.

[0012] Furthermore, the outer circumference of the splicing pipe has three centrally symmetrically distributed clamping surfaces near the top. The drive module includes a drive housing with a handle on its outer wall. The lower surface of the drive housing has a reserved output shaft, and a hexagonal fixing post is fixed to the bottom of the output shaft. Three centrally symmetrical sides of the hexagonal fixing post are hinged with movable grippers. A retaining spring is fixed between the end of the three movable grippers near the drive housing and the hexagonal fixing post. The inner side of the bottom of the three movable grippers fits perfectly with the three clamping surfaces, and the side of the three movable grippers away from the splicing pipe is fitted with the same tightening frame.

[0013] Furthermore, a compression spring is fixed to the bottom end of the hexagonal fixing post, and a pressure plate is fixed to the bottom end of the compression spring. The size of the pressure plate is adapted to the size of the top opening of the splicing pipe. Through the pressure plate and the compression spring, pressure can be transmitted to the drill pipe module more effectively.

[0014] Furthermore, the support frame includes a fixed outer frame, and a plurality of anti-detachment blocks are fixed to the outer wall of the fixed outer frame in a centrally symmetrical manner. Each anti-detachment block is fitted with an outwardly inclined support leg. A fixed ring is fixed in the middle of the fixed outer frame, and three inclined rollers are arranged in a centrally symmetrical manner on the lower surface of the fixed ring. The roller surface of the inclined rollers is tangent to the outer wall of the splicing pipe that vertically passes through the middle of the fixed ring. By setting a support frame with inclined rollers, the drill rod module can maintain a predetermined trajectory as much as possible when drilling downwards.

[0015] Furthermore, a positioning pin is provided near the top of the side of the support leg away from the fixing ring, and a positioning oblique hole is provided at the bottom of the support leg. When fixing, a rod-shaped object can be nailed into the positioning oblique hole to improve the stability of the support frame.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. By setting a connection method with a locking mechanism, the density of the threads can be reduced and the width of the teeth can be increased, thereby improving the tensile strength after engagement. It can also complete the connection faster during screwing. In conjunction with the protrusion that passes through two docking targets at the same time, the tensile strength and anti-disengagement performance of the drill pipe module can be improved, thus allowing the drill pipe module to drill deeper.

[0018] 2. By setting anti-detachment protrusions embedded in the inner groove, the anti-detachment effect can be improved in terms of physical structure. In addition, welding fixation makes the drill bit ring more firmly attached to the bottom end of the drill bit tube.

[0019] 3. The clamping frame, which is set with three movable claws, can be fixed together. When drilling is required, simply squeeze the three movable claws towards the end of the clamping spring at the same time, then clamp the clamping cut surface at the top of the spliced ​​pipe after docking, and then slide the clamping frame upward to fit and fix the three movable claws.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] In this embodiment, refer to Figure 1-10 This solution provides a geological exploration equipment, specifically including a drive module 1, a support frame, and a drill pipe module. The drill pipe module includes a splicing pipe 7 and a drill bit pipe 8 of the same diameter, with the wall thickness of the splicing pipe 7 equal to the wall thickness of the drill bit pipe 8. A drill bit ring 801 is welded and fixed to the bottom end of the drill bit pipe 8. The top ends of the drill bit pipe 8 and the top ends of the splicing pipe 7 have annular grooves of the same size on their inner circumferences, and the inner circumferences of the annular grooves are both provided with threaded grooves 19. The bottom end of the splicing pipe 7 has a threaded pipe 703 with a wall thickness less than that of the splicing pipe 7, and the length of the threaded pipe 703 is equal to the height of the annular groove. The threaded pipe 703 and the threaded groove 19 form a threaded connection, and the inner diameter of the threaded pipe 703 is equal to the inner diameter of the splicing pipe 7. The outer circumferences of the drill bit pipe 8 and the splicing pipe 7 near their top ends are both provided with strip-shaped grooves 16 of the same structure, and the extension of the strip-shaped grooves 16... The direction is parallel to the axis of the splicing pipe 7. The top of the strip groove 16 extends to the middle of the threaded groove 19. The top and bottom of the strip groove 16 are provided with through holes 17 that communicate with the interior. The threaded pipe 703 is provided with a positioning pin hole 704 that is coaxial with the through hole 17. A locking mechanism 14 is slidably connected in the strip groove 16. The locking mechanism 14 includes a slide bar. The top of the slide bar is reserved with a protrusion 143 that can be inserted into the through hole 17 and the positioning pin hole 704 at the same time. By setting the connection method with the locking mechanism 14, the density of the thread can be reduced and the width of the teeth can be increased, thereby improving the tensile strength after engagement. And the docking can be completed faster during screwing. With the protrusion 143 that passes through two docking targets at the same time, the tensile strength and anti-disengagement performance of the drill pipe module can be improved, thereby allowing the drill pipe module to drill deeper.

[0033] Reference Figures 7-8 The inner circumference of the drill tube 8 has multiple centrally symmetrically distributed embedded grooves 802 near the bottom. The inner circumference of the drill ring 801 has anti-detachment protrusions that are compatible with the embedded grooves 802 near the top. The anti-detachment protrusions are in an inverted "L" shape. By setting anti-detachment protrusions embedded in the embedded grooves 802, the anti-detachment effect can be improved in terms of physical structure. In addition, welding fixation makes the drill ring 801 more firmly attached to the bottom of the drill tube 8.

[0034] Reference Figures 8-10 The inner walls of the two opposite sides of the strip groove 16 are respectively provided with side grooves 18, and the openings of the two side grooves 18 are opposite each other and in the same direction of extension as the strip groove 16. On the opposite sides of the end of the slide bar away from the protrusion 143, coaxial protrusions 141 are respectively reserved, and the two protrusions 141 are slidably connected in the two side grooves 18. A through block turning hole 146 is provided at the end of the slide bar near the protrusion 143 on the same side as the protrusion 141. A strip-shaped abutment 142 is rotatably connected in 146. The height of the abutment hole 146 is adapted to the width of the side sliding groove 18. The strip-shaped abutment 142 can rotate freely in the abutment hole 146. When the strip-shaped abutment 142 rotates to a horizontal state, its two ends are inserted into the side sliding grooves 18 on both sides. At this time, the slide bar is fixed in the strip-shaped sliding groove 16 to prevent the protrusion 143 inserted into the positioning pin hole 704 and the through hole 17 from falling off during the drilling process.

[0035] Reference Figures 8-9 The slider rod has an adjusting screw hole 144 on the side away from the protrusion 143, which is connected to the rotating hole 146 of the abutment. The center line of the adjusting screw hole 144 coincides with the center line of the rotating hole 146 of the abutment. The strip abutment 142 has a square hole on the side near the adjusting screw hole 144, and an internal hexagonal stud 145 is screwed into the adjusting screw hole 144. The end of the internal hexagonal stud 145 near the strip abutment 142 has a square strip that matches the square hole. When it is necessary to rotate the strip abutment 142, simply screw the internal hexagonal stud 145.

[0036] Reference Figure 8 The end of the internal hexagonal stud 145 away from the strip-shaped abutment 142 has a marking hole, and the position of the marking hole is consistent with the pointing direction of the strip-shaped abutment 142. Through the marking hole, the state of the strip-shaped abutment 142 in the abutment hole 146 can be known, and locking and unlocking can be completed more quickly.

[0037] Reference Figure 3The outer circumference of the splicing pipe 7 is provided with a pointing tip 701 at one end near the threaded pipe 703, and the pointing tip 701 is located directly above the positioning pin hole 704. By setting the pointing tip 701, the position of the positioning pin hole 704 can be quickly determined, so that the positioning pin hole 704 and the through hole 17 can be aligned more quickly when assembling and docking the drill pipe module.

[0038] Reference Figure 2 and Figure 4 The outer circumference of the splicing pipe 7 has three centrally symmetrical clamping surfaces 702 near the top. The drive module 1 includes a drive housing with a handle on its outer wall. The lower surface of the drive housing has a reserved output shaft, and the bottom end of the output shaft is fixed with a hexagonal fixing post 13. Three of the centrally symmetrical sides of the hexagonal fixing post 13 are hinged with movable claws 3. The end of the three movable claws 3 near the drive housing is fixed with a clamping spring 2. The inner side of the bottom end of the three movable claws 3 fits perfectly with the three clamping surfaces 702. The side of the three movable claws 3 away from the splicing pipe 7 is fitted with the same tightening frame 11. With this configuration, when drilling is required, simply squeeze the end of the three movable claws 3 near the clamping spring 2 towards the middle at the same time, then clamp the clamping surfaces 702 at the top of the splicing pipe 7 after docking, and then slide the tightening frame 11 upward to fit and fix the three movable claws 3.

[0039] Reference Figure 2 and Figure 4 A compression spring 15 is fixed to the bottom end of the hexagonal fixing post 13, and a pressure plate 12 is fixed to the bottom end of the compression spring 15. The size of the pressure plate 12 is adapted to the size of the top opening of the splicing pipe 7. Through the pressure plate 12 and the compression spring 15, pressure can be transmitted to the drill pipe module more effectively.

[0040] Reference Figures 2-3 The support frame includes a fixed outer frame 10. Multiple anti-detachment blocks 9 are fixed on the outer wall of the fixed outer frame 10 in a centrally symmetrical manner. Each anti-detachment block 9 is fitted with an outwardly inclined support leg 5. A fixed ring 4 is fixed in the middle of the fixed outer frame 10. Three inclined rollers 6 are arranged in a centrally symmetrical manner on the lower surface of the fixed ring 4. The roller surface of the inclined rollers 6 is tangent to the outer wall of the splicing pipe 7 that passes vertically through the middle of the fixed ring 4. By setting a support frame with inclined rollers 6, the drill rod module can maintain the predetermined trajectory as much as possible when drilling downwards.

[0041] Reference Figure 3 A positioning pin 502 is provided on the side of the support leg 5 away from the fixing ring 4 near the top, and a positioning oblique hole 501 is provided at the bottom end of the support leg 5. When fixing, a rod-shaped object can be nailed into the positioning oblique hole 501 to improve the stability of the support frame.

[0042] Working principle: Before use, the internal hexagon stud 145 is tightened with a special small wrench until both ends of the strip-shaped abutment 142 disengage from the two side sliding grooves 18. Then, the protruding post 143, together with the sliding rod, is rotated around the protruding shaft 141 until the protruding post 143 disengages from the through hole 17. Next, the threaded tube 703 at the bottom of the splicing pipe 7 to be connected is slowly screwed into the threaded groove 19 at the top of the drill bit tube 8 until it is fully screwed in. At this point, the locating pin hole 704 is aligned with the through hole 17. Then... Then rotate the slide bar in the opposite direction around the convex shaft 141, so that the convex post 143 is simultaneously inserted into the aligned through hole 17 and the positioning pin hole 704. Finally, screw the internal hexagon stud 145 so that the two ends of the strip block 142 are inserted into the side sliding grooves 18 on both sides to lock the slide bar. Finally, insert the assembled drill rod module into the middle of the support frame and install the drive module to start drilling. When installing the next splicing pipe 7, the steps are the same as the installation method of the first splicing pipe 7.
