Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and in particular to a portable drilling device for geological exploration. Background Technology

[0002] Geological exploration is a scientific and engineering activity used to study and understand the Earth's internal structure, geological features, and resource distribution. Its main purpose is to obtain information about the Earth's crust and subsurface to support various applications, including resource exploration, environmental protection, land planning, and geological hazard prediction. During geological exploration, workers need to use drilling rigs for drilling operations. However, most existing drilling rigs have a single structural function, are too bulky and inconvenient to move and carry, and do not effectively handle the vibrations generated during drilling, leading to deviations in the drilling position. To address these issues, improvements are needed to the drilling equipment used in geological exploration. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a portable drilling device for geological exploration. This invention employs a damping structure, which includes a housing frame, a first slide rod, a spring, and an energy dissipator. When the drill rod drills, it vibrates, and the housing frame vibrates simultaneously. The first slide rod exerts a force on the energy dissipator, and the energy dissipator exerts a counterforce on the first slide rod to counteract the force exerted by the drill rod vibration on the first slide rod. As a result, the vibration amplitude of the housing frame is reduced under the action of the energy dissipator, and the vibration amplitude of the steel beam platform connected to the housing frame is also reduced, thus solving the problem of drill rod position displacement caused by vibration.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a portable geological exploration drilling device, the drilling device comprising a steel beam platform, a platform support, a geological exploration device placed on the platform support, and a damping structure placed on the steel beam platform. The platform support is movably installed on the upper side of the steel beam platform. The damping structure comprises a receiving frame, a first sliding rod, and an energy dissipator. The receiving frame is a hollow structure. There are multiple first sliding rods, which are respectively installed on the four side walls of the receiving frame. The energy dissipator is disposed in the hollow cavity of the receiving frame. Each first sliding rod is provided with a spring. The spring is located between the end of the first sliding rod near the energy dissipator and the inner side wall of the receiving frame, and the spring can push the end of the first sliding rod to press against the outer side wall of the energy dissipator.

[0005] Preferably, the drilling device further includes a polytetrafluoroethylene plate, the energy consumer is a hollow square box, and the polytetrafluoroethylene plate is disposed at the bottom of the energy consumer.

[0006] Preferably, the platform support includes two support rods and a movable platform. The movable platform is mounted on the two support rods. The two support rods are arranged in parallel and the bottom of each support rod is detachably connected to the steel beam platform. The two support rods form an L-shaped structure after being connected to the steel beam platform. The support rod is the vertical end of the L-shaped structure, and each support rod is provided with a rack along its length.

[0007] Preferably, the geological exploration device includes a first hydraulic motor, a second hydraulic motor, a connecting rod, and a drill rod. The first hydraulic motor is mounted on the upper side of the movable platform, and its output shaft passes downward through the movable platform and connects to the top of the drill rod. The second hydraulic motor is mounted on the side wall of the movable platform, and its output shaft is connected to the connecting rod. Both ends of the connecting rod are rotatably connected to the movable platform. The connecting rod is equipped with two gears, which mesh with racks on two support rods respectively.

[0008] Preferably, the first slide rod has a first through hole at its middle along its length direction, and a limiting rod is slidably provided near the first slide rod in the accommodating frame. The outer diameter of the limiting rod is consistent with the inner diameter of the first through hole. When the first slide rod is compressed by the spring and the first through hole reaches the outside of the accommodating frame, the limiting rod is pushed into the first through hole so that the first slide rod is away from the energy consumer. A rubber gasket is provided at the end of the first slide rod near the energy consumer.

[0009] Preferably, a protective shell is provided on the lower side of the steel beam platform. A third hydraulic motor is installed on one side of the protective shell. The output end of the third hydraulic motor is equipped with a threaded rod with opposite thread directions on both sides. The end of the threaded rod away from the third hydraulic motor is rotatably connected to the protective shell. Movable seats are threaded onto both sides of the threaded rod. Connecting parts are installed on the front and rear sides of each movable seat. A first connecting rod is hinged to the lower side of each connecting part. A support plate is hinged to the end of the first connecting rod away from the connecting part. Limiting blocks are provided at the left and right ends of the support plate. The limiting blocks are slidably connected to the limiting grooves on the inner side of the protective shell. Universal wheels are provided at the four corners of the lower side of the support plate.

[0010] Preferably, two second slide rods are provided between the inner walls of the left and right ends of the protective shell. The two second slide rods are located on the front and rear sides of the threaded rod respectively and are arranged in parallel. The second slide rods pass through the connector and are slidably connected with the connector.

[0011] Preferably, a fixing block is provided at each of the four lower corners of the outer side of the protective shell, and a long tapered rod is internally threaded onto the fixing block.

[0012] Preferably, push handles are installed on both the left and right sides of the protective shell.

[0013] Preferably, a hydraulic station is provided on the side of the steel beam platform near the second hydraulic motor. The hydraulic station is placed on the ground and is connected to the first hydraulic motor, the second hydraulic motor and the third hydraulic motor respectively.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This invention employs a damping structure, which includes a receiving frame, a first sliding rod, a spring, and an energy dissipator. When the drill rod vibrates during drilling, the receiving frame vibrates simultaneously. The first sliding rod exerts a force on the energy dissipator, and the energy dissipator exerts a counterforce on the first sliding rod to counteract the force exerted by the drill rod vibration on the first sliding rod. As a result, the vibration amplitude of the receiving frame decreases under the action of the energy dissipator, and the vibration amplitude of the steel beam platform connected to the receiving frame decreases synchronously, thus solving the problem of drill rod position displacement caused by vibration.

[0016] 2. This invention uses a detachable support rod and steel beam platform. When in use, the support rod is connected to the support rod connecting seat on the steel beam platform. After use, the support rod is removed from the support rod connecting seat, which solves the problem of the drilling device being difficult to carry.

[0017] 3. This invention uses a support plate that can move up and down. A caster wheel is set on the lower side of the support plate. When the equipment needs to be moved, the support plate is slid down to make the caster wheel contact the ground. The caster wheel pushes the equipment to move. After reaching the drilling location, the support plate is slid up to make the caster wheel leave the ground, thus solving the problem of the drilling device being difficult to move.

[0018] 4. The present invention has a fixing block on the outside of the protective shell and a long push rod inside the fixing block. After the caster wheel is off the ground, the long push rod is rotated to make the long push rod rotate into the soil. Adjusting the depth of the long push rod inserted into the soil can also keep the equipment horizontal, thus solving the problems of inconvenient and unstable fixing of the drilling device.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0038] like Figures 1 to 3 As shown, the drilling apparatus includes a steel beam platform 1, a platform support 2, a geological exploration device placed on the platform support 2, and a damping structure placed on the steel beam platform 1. The platform support 2 is movably installed on the upper side of the steel beam platform 1. The damping structure includes a receiving frame 3, a first sliding rod 4, and an energy dissipator 5. The receiving frame 3 is a hollow structure. There are multiple first sliding rods 4, which are respectively installed on the four sides of the receiving frame 3. The energy dissipator 5 is set in the hollow cavity of the receiving frame 3. Each first sliding rod 4 is equipped with a spring 6. The spring 6 is located between the end of the first sliding rod 4 near the energy dissipator 5 and the inner side wall of the receiving frame 3, and the spring 6 can push the end of the first sliding rod 4 to press against the outer side wall of the energy dissipator 5.

[0039] The accommodating frame 3 is a hollow square structure. Two second through holes 33 are provided on the four sides of the square structure. There is a distance between the two second through holes 33 on the same side wall. A first sliding rod 4 passes through each second through hole 33. After passing through the second through hole 33, the first sliding rod 4 is pressed against the energy consumer 5.

[0040] When the drilling device vibrates, the housing frame 3 vibrates simultaneously with the direction of the drilling device's vibration. When the housing frame 3 moves to the right, the first slide rods 4 on both sides of the housing frame 3 move to the right simultaneously. When the first slide rod 4 on the left side of the energy consumer 5 moves to the right, it exerts a rightward force on the energy consumer 5. The energy consumer 5 exerts a reverse force on the first slide rod 4, causing the first slide rod 4 to maintain its original state under the action of the spring 6. At the same time, the first slide rod 4 on the right side of the energy consumer 5 also maintains its original state due to the action of the spring 6. Therefore, the vibration amplitude of the housing frame 3 decreases under the action of the first slide rod 4. Since the housing frame 3 is connected to the steel beam platform 1, the vibration amplitude of the steel beam platform 1 decreases. The vibration amplitude of the platform support 2 on the steel beam platform 1 decreases, and thus the vibration amplitude of the geological exploration device on the platform support 2 decreases.

[0041] The drilling rig also includes a polytetrafluoroethylene (PTFE) plate. The energy consumer 5 is a hollow square box, with the PTFE plate located at the bottom. The hollow cavity of the energy consumer 5 can be filled with any solid material.

[0042] By utilizing the low coefficient of friction of the polytetrafluoroethylene (PTFE) sheet, the energy dissipator 5 reduces friction during its left-right sliding motion, thereby improving its energy dissipation effect on the first sliding rod 4. During use, to increase the weight of the energy dissipator 5 and further enhance its energy dissipation effect, a solid material can be filled into the hollow cavity of the energy dissipator 5. This solid material can be soil, sand, or other readily available materials from the surrounding borehole, depending on the site conditions. After the hollow cavity of the energy dissipator 5 is filled with solid material, the energy dissipator 5, through its own weight and reaction force on the first sliding rod 4, can reduce the vibration amplitude of the steel beam platform 1. Furthermore, the hollow structure of the energy dissipator 5 facilitates its portability for personnel when traveling.

[0043] The platform support 2 includes two support rods 15 and a movable platform 16. The movable platform 16 is installed on the two support rods 15. The two support rods 15 are arranged in parallel and the bottom of the two support rods 15 are detachably connected to the steel beam platform 1. After the two support rods 15 are connected to the steel beam platform 1, they form an L-shaped structure. The support rods 15 are the vertical ends of the L-shaped structure. Each support rod 15 is provided with a rack 7 along its length.

[0044] The steel beam platform 1 is a square frame. Two support rod connecting seats (not shown in the figure) are provided at the ends of the steel beam platform 1 furthest from the receiving frame 3. These two supporting rod connecting seats are respectively located on the front and rear ends of the frame of the steel beam platform 1. During use, the support rods 15 are detachably installed within the supporting rod connecting seats, providing upward support to the movable platform 16. After use, the support rods 15 are separated from the supporting rod connecting seats, making the drilling equipment easy to carry. Racks 7 are located on the side of the support rods 15 furthest from the receiving frame 3, and the racks 7 on the two support rods 15 are parallel.

[0045] The geological exploration device includes a first hydraulic motor 8, a second hydraulic motor 9, a connecting rod 10, and a drill rod 11. The first hydraulic motor 8 is located on the upper side of the movable platform 16, and its output shaft passes downward through the movable platform 16 and connects to the top of the drill rod 11. The second hydraulic motor 9 is installed on the side wall of the movable platform 16, and its output shaft is connected to the connecting rod 10. Both ends of the connecting rod 10 are rotatably connected to the movable platform 16. Two gears 12 are provided on the connecting rod 10, and the two gears 12 mesh with the racks 7 on the two support rods 15 respectively.

[0046] The second hydraulic motor 9 drives the connecting rod 10 to rotate, and the connecting rod 10 drives the two gears 12 to rotate synchronously. The gears 12 move up and down along the rack 7 and drive the movable platform 16 to move up and down. When the gears 12 drive the movable platform 16 to move downward, they provide a downward force to the first hydraulic motor 8. The first hydraulic motor 8 drives the drill rod 11 to drill downward.

[0047] like Figure 2 , Figure 3 and Figure 5 As shown, a first through hole 13 is provided in the middle of the first slide rod 4 along its length direction. A limit rod 14 is slidably provided in the accommodating frame 3 near the first slide rod 4. The outer diameter of the limit rod 14 is consistent with the inner diameter of the first through hole 13. When the first slide rod 4 compresses the spring 6 and drives the first through hole 13 to the outside of the accommodating frame 3, it pushes the limit rod 14 into the first through hole 13 so that the first slide rod 4 is far away from the energy consumer 5. A rubber gasket 28 is provided at the end of the first slide rod 4 near the energy consumer 5.

[0048] A sliding limiting rod 14 is provided on the side wall of the receiving frame 3. When the first sliding rod 4 is pulled outward, the spring 6 is compressed along the first sliding rod 4, and the first through hole 13 moves outward simultaneously. When the first through hole 13 moves to the outer side wall of the receiving frame 3, it pushes the limiting rod 14 to insert into the first through hole 13, keeping the first through hole 13 outside the receiving frame 3. When the first through holes 13 on all the first sliding rods 4 around the receiving frame 3 are located outside the receiving frame 3 and the limiting rod 14 is inserted into the first through hole 13 in each of them, the restriction of the first sliding rod 4 on the energy consumer 5 is released. At this time, the energy consumer 5 can be removed from the receiving frame 3. The rubber gasket 28 can prevent the first sliding rod 4 from impacting the energy consumer 5 when it moves towards the energy consumer 5, thus preventing damage to the outer wall of the energy consumer 5.

[0049] like Figure 1 , Figure 4 and Figure 6 As shown, a protective shell 21 is provided on the lower side of the steel beam platform 1. A third hydraulic motor 29 is installed on one side of the protective shell 21. A threaded rod 30 with opposite thread directions on both sides is installed at the output end of the third hydraulic motor 29. The end of the threaded rod 30 away from the third hydraulic motor 29 is rotatably connected to the protective shell 21. Movable seats 31 are threadedly connected to the threads on both sides of the threaded rod 30. Connecting parts 18 are installed on the front and rear sides of each movable seat 31. A first connecting rod 19 is hinged to the lower side of each connecting part 18. A support plate 32 is hinged to the end of the first connecting rod 19 away from the connecting part 18. Limiting blocks 22 are provided at the left and right ends of the support plate 32. The limiting blocks 22 are slidably connected to the limiting groove 23 on the inner side of the protective shell 21. Universal wheels 20 are provided at the four corners of the lower side of the support plate 32.

[0050] The protective shell 21 can be two square plates, which are fixedly installed at the left and right ends of the lower side of the steel beam platform 1. Alternatively, the protective shell 21 can be four square plates, which are joined end-to-end and fixedly connected to the lower side of the steel beam platform 1. A third hydraulic motor 29 is installed on the side of the protective shell 21 away from the receiving frame 3. The output axis of the third hydraulic motor 29 passes through the side wall of the protective shell 21 and is fixedly connected to the threaded rod 30. The support plate 32 slides up and down along the limiting groove 23 via the limiting block 22, which restricts the direction of the support plate 32's up-and-down sliding.

[0051] like Figure 6 As shown, two second slide rods 17 are provided between the inner walls of the left and right ends of the protective shell 21. The two second slide rods 17 are located on the front and rear sides of the threaded rod 30 respectively and are arranged parallel to each other. The second slide rods 17 pass through the connector 18 and are slidably connected to the connecting rod 18. The third hydraulic motor 29, the threaded rod 30, the connector 18, the second slide rods 17 and the first connecting rod 19 form a lifting mechanism that pushes the support plate 32 to move up and down.

[0052] In use, the third hydraulic motor 29 drives the threaded rod 30 to rotate, and the two movable seats 31 on the threaded rod 30 rotate in opposite directions. The connecting piece 18 connected to the movable seat 31 moves in opposite directions along the second slide rod 17. Then, the connecting piece 18 drives the support plate 32 to move up or down along the limiting groove 23 through the first connecting rod 19. When the third hydraulic motor 29 drives the threaded rod 30 to rotate, the two movable seats 31 move closer to each other. Then, the connecting parts 18 on both sides of the second slide rod 17 move closer to each other under the drive of the movable seats 31. The first connecting rod 19 pushes the support plate 32 to move downward along the direction of the limiting groove 23. The universal wheel 20 moves downward synchronously. Therefore, when the two movable seats 31 move closer to each other, they can drive the universal wheel 20 to move downward. At this time, the equipment can be moved by the universal wheel 20. If the two movable seats 31 move away from each other, the connecting parts 18 on both sides of the second slide rod 17 move away from each other under the drive of the movable seats 31. The first connecting rod 19 drives the support plate 32 to move upward along the direction of the limiting groove 23. The universal wheel 20 moves upward synchronously. At this time, the universal wheel 20 is lifted off the ground.

[0053] like Figure 1 and Figure 2 As shown, a fixing block 24 is provided at each of the four lower corners of the outer side of the protective shell 21, and a long tapered rod 25 is internally threaded onto the fixing block 24.

[0054] The fixing block 24 is located on the lower outer side of the protective shell 21. The fixing block 24 can limit the position of the long conical rod 25. Rotating the long conical rod 25 can insert it into the soil. By adjusting the depth of insertion of the long conical rod 25 into the soil, the equipment can be kept horizontal. Keeping the equipment horizontal can prevent the drill rod 11 from deviating from the original drilling point during drilling. The long push rod 25 can fix the drilling device to the ground to prevent shaking during operation. If there is a gap between the bottom of the fixing block 24 and the soil after the long conical rod 25 is inserted into the soil, a shim can be inserted into the gap between the fixing block 24 and the soil. The shim will keep the fixing block 24 at its initial height, preventing the long conical rod 25 from continuing to insert into the soil during drilling, which would cause the fixing block 24 to move downwards, making the equipment unable to remain horizontal and affecting the drilling direction of the drill bit.

[0055] like Figure 1 and Figure 2 As shown, push handles 26 are installed on both the left and right sides of the protective shell 21.

[0056] When the device needs to be moved, it can be moved by pushing the armrest 26.

[0057] like Figure 1 and Figure 2As shown, a hydraulic station 27 is provided on the side of the steel beam platform 1 near the second hydraulic motor 9. The hydraulic station 27 is placed on the ground and is connected to the first hydraulic motor 8, the second hydraulic motor 9 and the third hydraulic motor 29 respectively.

[0058] The hydraulic station 27 can drive the first hydraulic motor 8, the second hydraulic motor 9 and the third hydraulic motor 29 to operate respectively.

[0059] In use, the third hydraulic motor 29 is started, which drives the support plate 32 to slide upward along the limiting groove 23. After the caster wheel 20 leaves the ground, the third hydraulic motor 29 stops working. At this time, the bottom of the protective shell 21 contacts the ground. The long cone rod 25 is rotated to insert it into the soil along the fixing block 24. At the same time, the depth of the four long cone rods 25 inserted into the soil can be adjusted to keep the steel beam platform 1 horizontal. Then, the support rod 15 is installed on the support rod connecting seat, the movable platform 16 is installed on the support rod 15, the energy consumer 5 is placed in the receiving frame 3, and the limiting rod 14 is slid out of the first through hole 13. Rod 4 is pressed against energy consumer 5 by spring 6. Solid materials readily available at the construction site are added to energy consumer 5 according to the site conditions. Finally, the first hydraulic motor 8 and the second hydraulic motor 9 are started. The second hydraulic motor 9 drives gear 12 to rotate. Gear 12 drives the movable platform 16 to move downward along rack 7. The first hydraulic motor 8 drives the drill rod 11 to drill downward along the ground surface under the drive of the movable platform 16. The drill rod 11 vibrates during the downward drilling process. The vibration is weakened by the interaction of energy consumer 5, housing frame 3 and first slide rod 4, avoiding the problem of drill rod 11 being misaligned due to severe equipment vibration. After use, the support rod 15 is separated from the support rod connecting seat, and the first slide rod 4 is pulled outward to insert the limiting rod 14 into the first through hole 13. A distance is left between the first slide rod 4 and energy consumer 5. The solid materials in energy consumer 5 are taken out, and the long tapered rod 25 is screwed out of the ground. Then, the third hydraulic motor 29 is started to make the caster wheel 20 contact the ground. The equipment is then moved by pushing the handle 26. The problem of drilling position deviation caused by vibration during drilling was solved by the energy dissipator 5, the housing frame 3, and the first slide bar 4.

[0060] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
