Description

Technical Field

[0001] The invention relates to the technical field of geological prospecting sampling, in particular to geological prospecting drilling sampling equipment. Background Art

[0002] The geological prospecting drilling sampling device is an indispensable and important tool in modern geological science and engineering technology. The drilling mechanism is usually composed of a drill pipe, a drill bit and a drilling power system. The drill pipe is usually made of high-strength steel, and the drill bit is selected according to the geological conditions. The sampling system is its core part, including core drilling sampling and cuttings drilling sampling, which are used to obtain continuous core samples or loose granular cuttings samples. Some equipment also includes auxiliary equipment such as mud circulation systems, support structures, safety protection equipment, sampling containers and identification systems to support drilling operations.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] Depend on Figures 1 to 6 The geological prospecting drilling sampling equipment of the present invention comprises a bridge gantry 1, both sides of the bottom end of the bridge gantry 1 are equipped with a Fuma wheel 2, a convex slide 3 is slidably installed on the top of the bridge gantry 1, and an X-axis positioning unit 4 for driving the convex slide 3 to slide horizontally is installed on the outer wall of one side of the bridge gantry 1. The convex slide 3 is driven to move horizontally by the X-axis positioning unit 4, and the operator can fine-tune the position of the convex slide 3 according to the drilling needs;

[0038] A double-layer right-angle frame 5, the double-layer right-angle frame 5 is installed on one side outer wall of the convex slide 3, and a spline-type lifting drilling sampling module 9 for drilling sampling is arranged inside the double-layer right-angle frame 5, a middle partition 6 is fixed on the outer wall of one side of the double-layer right-angle frame 5 away from the convex slide 3, and a stuffing box 7 is installed on one side outer wall of the middle partition 6, and a bending plate 601 extending toward the direction of the spline-type lifting drilling sampling module 9 is integrally formed at the bottom end of the middle partition 6, and a circular notch 602 is arranged on one side outer wall of the bending plate 601;

[0039] The X-axis positioning unit 4 can move the wheeled backfill module 8 to the position above the predetermined hole, ensuring accurate placement of the filler and avoiding waste and uneven distribution;

[0040] The belt wheel backfill module 8 is installed on the side slope wall of the stuffing box 7. The bottom end of the stuffing box 7 is installed with a material control structure. The output end of the spline lifting drilling sampling module 9 is installed with a belt wheel transmission module 10 for maintaining power connection with the input end of the belt wheel backfill module 8.

[0041] The control panel 11 is installed on one side of the surface of the bridge gantry 1. The output end of the control panel 11 is electrically connected to the input end of the X-axis positioning unit 4 and the spline-type lifting drilling sampling module 9. The control panel 11 includes functions such as drilling speed, pressure control and speed adjustment to ensure accurate control and real-time monitoring of the drilling process. The operator can adjust and optimize the drilling parameters through the control panel 11 to cope with different geological conditions and sampling requirements.

[0042] It should be noted that the pulley transmission module 10 serves to connect the pulley backfill module 8 and the spline-type lifting drilling sampling module 9, so that the pulley backfill module 8 and the spline-type lifting drilling sampling module 9 work under the drive of a motor. By controlling the speed and power of the direct drive motor 902, the movement speed and strength of the pulley backfill module 8 can be accurately adjusted to ensure the accurate backfilling of soil into the drill hole.

[0043] The X-axis positioning unit 4 includes a first cylinder 401 installed on the outer wall of one side of the bridge gantry 1 and two parallel horizontal columns 402 horizontally fixed on the top of the bridge gantry 1. A square sleeve 403 is slidably installed on one end of the surface of the horizontal column 402, and the convex slide 3 is fixed between the two square sleeves 403.

[0044] A longitudinal beam is fixed between the two transverse columns 402 , and a through hole is provided inside the longitudinal beam for the piston rod of the first cylinder 401 to pass through.

[0045] It should be noted that the longitudinal beam is one of the main structures supporting the bridge gantry 1 and other components. Through the internal through-hole design, the piston rod of the first cylinder 401 can directly pass through the longitudinal beam to transfer the force to the bridge gantry 1 or other components that need to be moved; the through-hole design allows the piston rod of the first cylinder 401 to be directly embedded in the longitudinal beam. This direct connection method helps to improve the operating stability of the equipment.

[0046] When the X-axis positioning unit 4 is working, the extension and retraction amount of the first cylinder 401 is controlled by the control panel 11. The first cylinder 401 can also be replaced by an electric push rod. The piston rod of the first cylinder 401 drives the convex slide 3 and the square sleeve 403 to slide in the extension direction of the cross column 402. At this time, the convex slide 3 drives the stuffing box 7 and the wheeled backfilling module 8 to move together through the double-layer right-angle frame 5 and the middle partition 6, so as to adjust the horizontal drilling point of the spline-type lifting drilling sampling module 9 and the soil backfilling position of the wheeled backfilling module 8, so as to ensure the accuracy of the drilling sampling and soil backfilling actions.

[0047] Embodiment 2

[0048] Based on the first embodiment, Figure 7 , Figure 8 and Fig. 9 Given.

[0049] The spline-type lifting drilling sampling module 9 includes a hollow vertical frame 901 fixed inside the double-layer right-angle frame 5, a spline telescopic shaft 903 rotatably installed inside the hollow vertical frame 901, a second cylinder 904 installed on the outer wall of one side of the double-layer right-angle frame 5, a bearing plate 906 fixed at the bottom end of the piston rod of the second cylinder 904, and a drill barrel 905 rotatably installed at the bottom end of the bearing plate 906, the top end of the drill barrel 905 is fixedly connected to the bottom end of the spline telescopic shaft 903, and the top end of the hollow vertical frame 901 is installed with a direct drive motor 902 for interconnecting with the top end of the spline telescopic shaft 903.

[0050] During the operation of the spline lifting drilling sampling module 9, the second cylinder 904 controls the bearing plate 906 and the drill barrel 905 to actively move downward, and in this process, the direct drive motor 902 drives the spline telescopic shaft 903 to rotate. The spline telescopic shaft 903 can still drive the drill barrel 905 to rotate while changing its length, thereby realizing the simultaneous lifting and rotating functions of the drill barrel 905. Then, the drill barrel 905 continues to penetrate into the soil under the thrust of the second cylinder 904, and the drilled soil will be retained in the drill barrel 905 until the drill barrel 905 moves downward to the limit position. The drilling depth is limited by the length of the spline telescopic shaft 903 and the cylinder length of the second cylinder 904, thereby realizing the drilling and sampling operation of the soil. After the sampling is completed, the second cylinder 904 drives the bearing plate 906, the drill barrel 905 and other components to move upward.

[0051] Furthermore, the present invention has a "F"-shaped rotating shaft 9061 rotatably installed inside the bearing plate 906, the bottom end of the "F"-shaped rotating shaft 9061 is fixedly connected to the top end of the drill tube 905, the spline telescopic shaft 903 includes an inner spline shaft installed on the output end of the direct drive motor 902 through a coupling, and an outer spline shaft installed in a sliding manner in the inner spline shaft, the bottom end of the outer spline shaft is fixedly connected to the top end of the "F"-shaped rotating shaft 9061, when the direct drive motor 902 drives the spline telescopic shaft 903 to rotate, the rotary power of the direct drive motor 902 is transmitted to the outer spline shaft through the inner spline shaft, and the "F"-shaped rotating shaft 9061 and the drill tube 905 are driven to rotate together through the outer spline shaft, the "F"-shaped rotating shaft 9061 and the drill tube 905 can be lifted and lowered under the drive of the bearing plate 906, and can also rotate together with the inner spline shaft;

[0052] A guide rail 907 is fixed on the outer wall of one side of the double-layer right-angle frame 5 close to the hollow vertical frame 901, and a slider 908 is slidably installed on the outer wall of one side of the guide rail 907. One end of the bearing plate 906 is fixedly connected to the outer wall of one side of the slider 908. When the bearing plate 906 is lifted or lowered, one end of the bearing plate 906 slides relative to the guide rail 907 through the slider 908. The slider 908 and the guide rail 907 ensure the lifting and lowering stability of the bearing plate 906, the drill barrel 905 and other components on the one hand, and also allow the drill barrel 905 to rotate stably on the other hand.

[0053] Embodiment 3

[0054] Based on the second embodiment, Fig.10 , Fig.11 and Fig.12 Given.

[0055] The material control structure includes a trapezoidal discharge box 701 installed at the bottom of the stuffing box 7, and a baffle plate 702 slidably inserted inside the trapezoidal discharge box 701. One end of the baffle plate 702 extends to the outside of the trapezoidal discharge box 701. When it is necessary to backfill the hole with soil, the staff manually pulls the baffle plate 702 so that the baffle plate 702 no longer blocks the bottom opening of the trapezoidal discharge box 701, ensuring that the soil in the stuffing box 7 falls smoothly into the wheeled backfill module 8. The design of the baffle plate 702 effectively prevents the soil from accidentally flowing out when backfilling is not needed, reducing the waste of resources, and can be flexibly adjusted according to actual conditions and operational requirements to ensure the accuracy of the backfilling process.

[0056] The wheeled backfill module 8 includes two parallel ribs 804 fixed on the slope wall of the stuffing box 7, a linear feeding rack 801 fixed at the bottom ends of the two ribs 804, and a wheeled feeding structure 803 installed inside the linear feeding rack 801 for receiving and conveying soil in the stuffing box 7. The ribs 804, on the one hand, serve to connect the linear feeding rack 801 and the stuffing box 7, and on the other hand, create a gap between the linear feeding rack 801 and the stuffing box 7 for the movement of soil, while allowing the soil to be stably conveyed between the two ribs 804.

[0057] The input end of the pulley feeding structure 803 and the spline telescopic shaft 903 are connected in power via a pulley transmission module 10 , and a plurality of U-shaped fixing frames 802 are installed on the back of the linear feeding frame 801 .

[0058] Specifically, the above-mentioned pulley transmission module 10 includes a right-angle platform 1001 fixed on the outer wall of one side of the hollow vertical frame 901, a transmission shaft 1002 rotatably installed inside the right-angle platform 1001, a bevel gear transmission structure 1003 installed at one end of the transmission shaft 1002 for connecting to the internal spline shaft, and a crawler transmission structure 1004 installed at the other end of the transmission shaft 1002 for connecting to the input end of the pulley feeding structure 803. The pulley transmission can smoothly transmit power and motion, reduce noise and mechanical wear caused by impact and vibration during the transmission process, and by selecting pulleys of different diameters, the transmission ratio can be adjusted to meet different speed and torque requirements.

[0059] When the direct drive motor 902 drives the spline telescopic shaft 903 to rotate, the inner spline shaft in the spline telescopic shaft 903 drives the transmission shaft 1002 to rotate through the bevel gear transmission structure 1003, and the rotational power of the transmission shaft 1002 is transmitted to the belt wheel feeding structure 803 through the crawler transmission structure 1004. Then, the soil falling on the belt wheel feeding structure 803 is actively transported along the extension direction of the slope of the stuffing box 7 and the bending plate 601 under the rotation of the belt wheel feeding structure 803 until the soil is backfilled into the hole;

[0060] Compared with manual operation, the motor-driven system is not limited by fatigue and working hours, and can continuously and accurately backfill soil, which greatly improves the efficiency of operation and ensures that each backfill operation reaches the designed soil quantity and uniformity.

[0061] When in use, the staff first moves the bridge gantry 1 and the equipment to the sampling point through the Foma wheel 2. The bridge gantry 1, as the main body of the overall structure of the equipment, provides a stable support and mobile platform, and moves on the ground through the Foma wheel 2 to accurately locate the drilling point. The Foma wheel 2 has good load-bearing capacity and stability, and has the ability to move and lift, and can adapt to the movement needs under different terrain conditions;

[0062] When the equipment reaches the designated position, the staff turns on the X-axis positioning unit 4 through the control panel 11 to start working, and the X-axis positioning unit 4 drives the convex slide 3, the double-layer right-angle frame 5, the middle partition 6, the stuffing box 7, the wheeled backfill module 8 and other structures to move in the X-axis direction, so that the entire spline-type lifting drilling sampling module 9 can be fine-tuned in the horizontal direction to quickly reach the best drilling position. Then the staff controls the spline-type lifting drilling sampling module 9 through the control panel 11 to work. The spline-type lifting drilling sampling module 9 is responsible for the actual drilling and sampling operations, that is, the spline-type lifting drilling sampling module 9 can perform downward movement and complete the sampling work;

[0063] When the spline-type lifting drilling sampling module 9 completes the soil sampling operation, it automatically resets and actively lifts the drilled soil until it is separated from the soil. The staff then turns on the X-axis positioning unit 4 and the wheeled backfill module 8 through the control panel 11 to work, and uses the stable support of the bridge gantry 1, the mobile positioning of the Foma wheel 2, and the fine-tuning of the X-axis positioning unit 4 to make the discharge end of the wheeled backfill module 8 located above the drilling hole. The staff then opens the material control structure at the bottom of the stuffing box 7, so that the material control structure is normally open, and then the soil in the stuffing box 7 enters the wheeled backfill module 8 under the action of gravity. The wheeled backfill module 8 accurately backfills the soil discharged from the stuffing box 7 into the drilled hole along the downslope of the bending plate 601, ensuring accurate delivery of the filler and avoiding waste and uneven distribution.

[0064] The above-mentioned equipment of the present invention can complete soil drilling and sampling work, and use the wheeled backfill module 8 to complete the backfill process of the hole without manual operation, reducing the time waste and inefficiency problems that may be caused by manual operation. In large-scale drilling operations, the saved time can be used to increase drilling points or perform other important geological exploration tasks, thereby improving overall work efficiency and output results. At the same time, the automatic backfilling function can accurately control the backfilling amount and distribution of soil materials, reduce soil loss during the filling process, and ensure the surface flatness and ecological environment stability after backfilling.
