Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to a drilling and inclination detection equipment used for geological exploration. Background Art

[0002] The main purpose of drilling inclination during geological survey is to ensure the verticality and accuracy of the borehole, avoid geological information errors caused by borehole deviation, and thus affect subsequent engineering design and construction. If the borehole is deviated, it may cause the collected data to be inaccurate and affect the judgment of the underground structure. Therefore, during geological exploration operations, it is necessary to place the drilling inclinometer at the borehole measurement site at regular intervals to measure the degree of borehole deviation.

[0003] When conducting drilling operations for geological surveys, in order to ensure the verticality and accuracy of the borehole and avoid geological information errors caused by borehole deviation, it is necessary to detect the inclination of the borehole at certain depths. During the detection, a cylindrical angle detector is generally placed into the borehole to detect the borehole inclination. However, due to the different borehole diameters, a larger borehole diameter requires a larger detector probe to ensure the accuracy and stability of the measurement. When measuring boreholes of different diameters, it is often necessary to replace probes of different diameters multiple times, which is inconvenient.

[0004] The patent document with the announcement number CN117514145B discloses a tool for measuring inclination while drilling. The device can enter the working state only when needed, with extremely low tool loss and power consumption, which greatly improves the overall endurance. However, the device is difficult to adapt to the inclination detection of inclined boreholes. Since vertical drilling and inclined drilling are generally used in geological surveys, the inclination measurement method of vertical boreholes is generally detected by measuring whether the central axis of the borehole has an angle change with the vertical line of the earth's center. When surveying and drilling inclined boreholes, if the central axis of the borehole is rotated and offset with the vertical line of the earth's center, this will cause the angle between the central axis of the borehole and the vertical line of the earth's center to remain unchanged, but the actual borehole orientation has deviated from the original borehole angle.

[0005] In addition, after measuring the borehole angle, the current drilling inclinometer used in geological survey still needs to compare the measured angle data with the original borehole angle data to analyze whether the angle has shifted, which makes it difficult for workers to quickly and intuitively confirm whether the measured area deviates from the initial angle. Therefore, we propose a drilling inclinometer for geological survey to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to make up for the shortcomings of the prior art and proposes a drilling inclination detection equipment for geological exploration.

[0009] A positioning mechanism is provided inside the storage tube, and the positioning mechanism includes a fixed column, an inner wall of the fixed column is slidably connected with a sliding rod, a positioning tube is fixed to the top of the sliding rod, a wiring harness transmitter is installed inside the positioning tube, and the positioning tube is adapted to the positioning hole. A limiting mechanism is also provided inside the storage tube, and the limiting mechanism is used to limit and fix the fixed column.

[0010] Specifically, a straight sleeve is provided inside the main tube, the central axis of the straight sleeve coincides with the central axis of the main tube, the straight sleeve is fixed to the storage tube, an electric push rod is fixed to the inner wall of the straight sleeve, a support frame is fixed to the telescopic end of the electric push rod, two slides are fixed to the outer surface of the blocking shell, both of the slides are slidably connected to the storage tube, both of the slides are fixed to the support frame, a cover plate is fixed to the outer surface of the blocking shell, and a launching rope is installed above the cover plate.

[0011] By adopting the above technical solution, the electric push rod is controlled to drive the support frame to move, and the support frame can drive the sealing shell to move, so that the sealing shell blocks the opening of the storage tube to prevent the internal parts of the storage tube from being hit by falling debris from the outside when testing the inclination. The pulley group is set to facilitate the sliding of the device in the drill hole.

[0012] A motor 1 is fixed to the inner wall of the straight sleeve, a one-way threaded rod is fixed to the output end of the motor 1, a threaded tube is threadedly connected to the outer surface of the one-way threaded rod, the clamping mechanism also includes a movable plate and two hinged rods, one end of the two hinged rods are hinged to the threaded tube, the other ends of the two hinged rods are hinged to the movable plate, a sliding frame is fixed to the outer surface of the straight sleeve, the sliding frame is slidably connected to the movable plate, a plurality of connecting columns are fixed between the movable plate and the clamping plate, and the plurality of connecting columns are slidably connected to the main tube.

[0013] By adopting the above technical solution, when the device is put into the borehole, the pulley group is used to enable the device to slide in the borehole. When the inclination is detected, the driving motor drives the one-way threaded rod to rotate, and the rotation of the one-way threaded rod drives the threaded tube to move. When the threaded tube moves, the clamping plate on the moving plate is driven by the hinged rod to approach the borehole wall, so that the three clamping plates move synchronously and clamp the borehole wall, so that the central axis of the main tube coincides with the central axis of the borehole, so that the device can adapt to boreholes of different diameters.

[0014] Furthermore, the vertical detection mechanism also includes a ring seat, a rotating ring and a rotating plate. The ring seat is fixed to the sealing shell. Two rotating rods 2 are fixed to the outer surface of the rotating ring. Both of the two rotating rods 2 are rotatably connected to the ring seat. Two scale rings 2 are fixed to the outer surface of the ring seat. Two groups of pointer blocks are fixed to the outer surface of the rotating ring. The number of pointer blocks in each group is two. The two groups of pointer blocks are respectively adapted to the two scale rings 2.

[0016] By adopting the above technical solution, the counterweight ball rotates freely under the action of gravity. After the counterweight ball stops, the central axis of the counterweight ball coincides with the vertical line of the center of the earth. If the borehole is tilted, the detection head records the angle change of the pointer column on the scale ring one and the angle change of the pointer block on the scale ring two, so as to calculate the offset slope of the borehole here.

[0018] By adopting the above technical solution, after the counterweight ball is stationary, the central axis of the counterweight ball coincides with the vertical line of the earth's center, and the rotating bidirectional threaded rod drives the two clamping half rings to approach each other. The two clamping half rings clamp and fix the anti-slip ring, thereby limiting and fixing the counterweight ball in a vertical state.

[0019] Furthermore, the positioning mechanism also includes a fixed ring rail, a pressure plate and a moving cylinder, the two sliding plates are fixed to the fixed ring rail, the pressure plate is located at the bottom of the fixed ring rail, two sliding blocks are fixed to the outer surface of the pressure plate, the two sliding blocks are slidably connected to the fixed ring rail, two limit plates are fixed to the outer surface of the moving cylinder, the two limit plates are slidably connected to the pressure plate, the top of the moving cylinder is fixedly connected to a spherical sleeve, the inner wall of the spherical sleeve is rotatably connected to a universal ball, the universal ball is fixed to a fixed column, a telescopic spring 1 is fixed to the bottom surface of the positioning tube, a baffle is fixed to the outer surface of the fixed column, and both ends of the telescopic spring 1 are respectively fixed to the baffle and the positioning tube.

[0020] By adopting the above technical solution, the original inclination of the borehole is marked and measured, the counterweight ball in a vertical state is first limited and fixed, and then the fixed column is freely moved, and the fixed column is quickly positioned by inserting the positioning tube into the positioning hole. At this time, the harness transmitter can be sensed by the double-hole harness receiver, because the central axis of the fixed column coincides with the central axis of the counterweight ball, that is, the central axis of the fixed column coincides with the vertical line of the center of the earth.

[0021] The inner wall of the above-mentioned moving cylinder is slidably connected with a push pressure column, the top of the push pressure column is provided with anti-slip grooves, the outer surface of the push pressure column is fixed with two push pressure plates, the two push pressure plates are both slidably connected with the moving cylinder, the upper surface of the pressure plate is fixed with two anti-slip edge strips, the two anti-slip edge strips respectively correspond to the two push pressure plates, the upper surfaces of the two push pressure plates are fixed with two telescopic springs, and the two telescopic springs are both fixed to the moving cylinder.

[0022] Furthermore, a linkage mechanism is provided on the outside of the two sliders, and the linkage mechanism includes a top pressure block and a slide rail, the slide rail is fixed to the slider, the inner wall of the slide rail is slidably connected with a brake block, the brake block is slidably connected to the slider, an extrusion rod is fixed on the outer surface of the brake block, an inclined slide groove matched with the extrusion rod is provided on the outer surface of the top pressure block, the extrusion rod is slidably connected to the inner wall of the inclined slide groove, a square rod is fixed on the upper surface of the top pressure block, a fixed seat is fixed on the upper surface of the slider, the square rod is slidably connected to the fixed seat, and a telescopic spring three is sleeved on the outer surface of the square rod, and the two ends of the telescopic spring three are respectively fixed to the fixed seat and the top pressure block.

[0023] Furthermore, the limiting mechanism includes a moving frame and a transmission circular plate, the outer surfaces of the two slides are fixed with limiting rods 2, the two limiting rods 2 are slidably connected to the moving frame, the moving frame is rotatably connected to the transmission circular plate, the bottom surface of the blocking shell is fixed with electric push rods 2, the telescopic end of the electric push rods 2 is fixed to the moving frame, the outer surface of the transmission circular plate is fixed with a gear ring, the lower part of the moving frame is fixed with motor 2, the output end of the motor 2 is fixed with a gear, and the gear is meshed with the gear ring.

[0024] By adopting the above technical scheme, when the main cylinder slides in the drill hole, the device may rotate as a whole in the drill hole. In order to prevent the device from rotating as a whole and causing the position of the fixed column to shift, resulting in the misalignment of the fixed column and the counterweight ball, the transmission circular plate is driven to rotate by driving motor 2. Since the transmission circular plate squeezes the pressure plate, the transmission circular plate and the pressure plate are frictionally connected, so that the rotation of the transmission circular plate drives the pressure plate to rotate, and the rotation of the pressure plate drives the fixed column to rotate around the central axis of the main cylinder, thereby avoiding the misalignment of the fixed column and the counterweight ball.

[0025] Compared with the prior art, the drilling and inclination detection equipment for geological exploration has the following beneficial effects: 1. The present invention sets a vertical detection mechanism and a positioning mechanism. When measuring the original inclination angle of the borehole, the counterweight ball rotates freely under the action of gravity. After the counterweight ball is stationary, the central axis of the counterweight ball coincides with the vertical line of the earth's center. The counterweight ball in a vertical state is limited and fixed, and the position of the fixed column is freely moved until the wire beam emitted by the wire beam transmitter can be sensed by the double-hole wire beam receiver. The fixed column is then limited and fixed. At this time, the central axis of the fixed column coincides with the vertical line of the earth's center. Then the device is placed in the detection area. If the borehole in the detection area is offset, the main cylinder follows the offset, so that the central axis of the fixed column cannot coincide with the central axis of the counterweight ball. At this time, the double-hole wire beam receiver cannot receive the rays of the wire beam transmitter. Through the information feedback of the double-hole wire beam receiver, the staff can directly confirm whether inclination occurs. The device can adapt to the inclination detection of inclined boreholes, and can quickly and intuitively confirm whether the measured area deviates from the initial angle.

[0026] 2. The present invention arranges a pulley block and a clamping mechanism. When the device is put into a borehole, the pulley block is used to enable the device to slide in the borehole. When the inclination is detected, the driving motor drives the one-way threaded rod to rotate, and the rotation of the one-way threaded rod drives the threaded tube to move. When the threaded tube moves, the clamping plate on the moving plate is driven to approach the borehole wall through the hinged rod, so that the three clamping plates move synchronously and clamp the borehole wall, so that the central axis of the main cylinder coincides with the central axis of the borehole, thereby enabling the device to adapt to boreholes of different diameters.

[0047] When the fixed column 608 needs to be locked, the electric push rod 806 is controlled to drive the moving frame 801 to move upward, so that the transmission circular plate 802 presses the pressure plate 602, the pressure column 614 and the pressure block 701, so that the position of the fixed column 608 is locked. At the same time, after the pressure plate 602 is pressed, the transmission circular plate 802 is frictionally connected with the pressure plate 602; After the top pressure column 614 is pressed, the top pressure column 614 will squeeze the universal ball 607 to limit and fix the universal ball 607 so that the universal ball 607 will not rotate with the spherical sleeve 606. When the top pressure column 614 is pressed, the top pressure plate 615 will squeeze the anti-slip edge strip 617 to limit and fix the moving cylinder 604 so that the moving cylinder 604 will not slide with the pressure plate 602. After the pressing block 701 is pressed, the inclined slide groove 702 will squeeze the pressing rod 703, so that the brake block 704 brakes the pressure plate 602, so that the pressure plate 602 does not rotate with the fixed ring rail 601.

[0048] Please refer to Figure 5 and Figure 6 The limiting mechanism 8 includes a moving frame 801 and a transmission circular plate 802. The outer surfaces of the two slide plates 10 are fixed with limiting rods 807. The two limiting rods 807 are both slidably connected to the moving frame 801. The moving frame 801 is rotatably connected to the transmission circular plate 802. An electric push rod 806 is fixed to the bottom surface of the blocking shell 3. The telescopic end of the electric push rod 806 is fixed to the moving frame 801. A gear ring 803 is fixed to the outer surface of the transmission circular plate 802. A motor 804 is fixed below the moving frame 801. A gear 805 is fixed to the output end of the motor 804. The gear 805 is meshed with the gear ring 803.

[0049] As the main cylinder 1 slides in the borehole, the device may rotate as a whole in the borehole. In order to prevent the device from rotating as a whole and causing the fixed column 608 to shift in position, resulting in the fixed column 608 and the counterweight ball 404 being misaligned, the transmission circular plate 802 is driven to rotate by the driving motor 804. As the transmission circular plate 802 squeezes the pressure plate 602, the transmission circular plate 802 and the pressure plate 602 are frictionally connected to each other, so that the rotation of the transmission circular plate 802 drives the pressure plate 602 to rotate, and the rotation of the pressure plate 602 drives the fixed column 608 to rotate around the central axis of the main cylinder 1, thereby avoiding the misalignment of the fixed column 608 and the counterweight ball 404.

[0050] Working principle: When checking the inclination of a borehole, please pay special attention to Fig.14 and Fig.15 At this time, it is necessary to mark and measure the original inclination of the borehole first, insert the main tube 1 into the borehole, control the three clamping plates 904 to clamp the borehole wall, so that the central axis of the main tube 1 coincides with the central axis of the borehole, control the electric push rod 13 to move the support frame 11, and move the positioning mechanism 6 from the inside of the storage tube 2 to the outside of the storage tube 2. The counterweight ball 404 rotates freely under the action of gravity. After the counterweight ball 404 is stationary, the central axis of the counterweight ball 404 coincides with the vertical line of the center of the earth. The rotating bidirectional threaded rod 501 drives the two clamping half rings 502 to approach each other. The two clamping half rings 502 clamp and fix the anti-slip ring 408, thereby limiting and fixing the counterweight ball 404 in a vertical state.

[0051] The fixed column 608 is freely moved, and the fixed column 608 is quickly positioned by inserting the positioning tube 609 into the positioning hole 413. At this time, the harness transmitter 610 can be sensed by the double-hole harness receiver 405, and then the electric push rod 806 is controlled to drive the movable frame 801 to move upward, so that the transmission circular plate 802 presses the pressure plate 602, the pressure column 614 and the pressure block 701. After the pressure column 614 and the pressure plate 602 are pressed, the fixed column 608 will be limited and fixed to lock the position of the fixed column 608. After the pressure plate 602 is pressed, the transmission circular plate 802 is connected to the pressure plate 602 through friction transmission.

[0052] After the fixed column 608 is limited and fixed, the central axis of the fixed column 608 coincides with the central axis of the counterweight ball 404, that is, the central axis of the fixed column 608 coincides with the vertical line of the center of the earth, and then the drilling and inclination detection are started. At this time, the limit of the counterweight ball 404 is cancelled, and the electric push rod 13 is controlled to move the positioning mechanism 6 into the storage tube 2, and then the device is placed in the detection area and fixed by clamping the borehole wall with three clamping plates 904. After waiting for the freely rotating counterweight ball 404 to stop, the driving motor 2 804 drives the transmission circular plate 802 to rotate, and the rotation of the transmission circular plate 802 drives the pressure plate 602 to rotate, and the rotation of the pressure plate 602 drives the fixed column 608 to rotate around the central axis of the main tube 1.

[0053] If the drilling hole in the detection area has not shifted, after the fixed column 608 rotates one circle around the central axis of the main tube 1, the central axis of the fixed column 608 can eventually move to coincide with the central axis of the counterweight ball 404. At this time, the double-hole wire beam receiver 405 can receive the rays of the wire beam transmitter 610. Through the information feedback of the double-hole wire beam receiver 405, the staff can directly confirm that the drilling hole in the detection area is not tilted.

[0054] If the drilling in the detection area is offset, the main cylinder 1 is offset along with the drilling, and the central axis of the fixed column 608 is also deflected relative to the vertical line of the center of the earth. When the fixed column 608 rotates one circle with the central axis of the main cylinder 1 as the center, the central axis of the fixed column 608 cannot coincide with the central axis of the counterweight ball 404. At this time, the double-hole wire beam receiver 405 cannot receive the rays of the wire beam transmitter 610. Through the information feedback of the double-hole wire beam receiver 405, the staff can directly confirm that the drilling hole is tilted, and then use the detection head 18 to record the deflection angle of the pointer column 406 and the pointer block 411, so as to calculate the offset slope of the drilling hole here.
