Description

A forward and reverse drilling rig for geological exploration Technical Field

[0001] This invention relates to the field of geological exploration technology, specifically to a forward and reverse drilling rig for geological exploration. Background Technology

[0002] Geological exploration involves using various methods to investigate and explore the geology, in order to understand the underground geological structure, mineral resource distribution, hydrogeological conditions, and other information. This provides data support for research in geology, geophysics, and other disciplines, and also provides a basis for engineering construction and implementation, ensuring the safety and stability of the project.

[0003] Drilling rigs are often used in geological exploration. However, existing equipment is large in size and weight, and during operation, it is subject to the reaction force of the soil layer, which may cause it to overturn. Therefore, we propose a new type of forward and reverse drilling rig for geological exploration. Summary of the Invention

[0004] The purpose of this invention is to provide a forward and reverse drilling rig for geological exploration, to solve the problem mentioned in the background art where the equipment is subject to the reaction force exerted by the soil layer, which may lead to the risk of overturning. To achieve the above objective, this invention provides the following technical solution: A forward and reverse drilling rig for geological exploration, including a base, which is the basic support structure of the entire drilling rig. A fixing assembly is provided inside the base, the fixing assembly including a hydraulic cylinder, which is fixedly connected inside the base. A hydraulic plug is movably connected inside the hydraulic cylinder, and a fixing cone is fixedly connected to one end of the hydraulic plug. A lowering drilling assembly is provided at the top of the base, the lowering drilling assembly including a motor, a rotating shaft movably connected inside the motor, a bevel gear fixedly connected to the side surface of the rotating shaft, a bevel gear meshing with one side of the bevel gear, a drill rod fixedly connected to the bottom of the bevel gear, a drill bit fixedly connected to the bottom of the drill rod, and drill blades fixedly connected to the side surface of the drill rod. Activating the fixing assembly... The hydraulic plug moves the fixed cone downwards, inserting it into the ground. This makes the device more stable, preventing displacement of the drilling rig during drilling and avoiding overturning due to the reaction force of the soil layer. This ensures the stability of the drilling rig. Then, motor one is started, causing rotating shaft one to drive bevel gear one to rotate. Simultaneously, bevel gear two, meshed on one side of bevel gear one, rotates, causing the drill rod, fixed to the bottom of bevel gear two, to drive the drill bit downwards to drill into the ground, obtaining samples or probing the geological structure. When the drill rod descends to the designated position, the two motors rotate in opposite directions, causing the drill rod to rise, withdrawing the drill bit, bringing soil out of the strata, and clearing debris to complete the geological exploration. It can also be used to try to release the drill in case of jamming, improving the practicality of the drilling rig and its ability to cope with complex geological conditions.

[0005] More preferably, a lifting block is fixedly connected to the bottom of the first motor, a fixing plate is fixedly connected to one end of the first motor by bolts, the fixing plate is fixedly connected to the top of the lifting block, and the drill rod is movably connected inside the lifting block.

[0006] More preferably, a lifting assembly is provided on one side of the lifting block. The lifting assembly includes a threaded rod, which is movably connected inside the lifting block. One end of the threaded rod is fixedly connected to a transmission wheel, and a rotating shaft is fixedly connected inside the transmission wheel. One end of the rotating shaft is movably connected to a motor. A transmission belt is movably connected to the side surface of the transmission wheel. The side of the transmission belt away from the transmission wheel is movably connected to the transmission wheel. A threaded rod is fixedly connected inside the transmission wheel. When the motor is started, the rotating shaft rotates, which in turn drives the transmission wheel to rotate, causing the threaded rod fixedly connected to the bottom of the transmission wheel to rotate. Simultaneously, the transmission belt drives the transmission wheel to rotate, causing the threaded rod fixedly connected to the bottom of the transmission wheel to rotate as well. This causes the lifting block, which is connected to the side surfaces of the threaded rods, to move the drill rod downwards until the drill bit inserts into the ground.

[0007] More preferably, a placement platform is movably connected to the side surface of the threaded rod, and the threaded rod passes through the placement platform.

[0008] More preferably, the bottom of the placement platform is fixedly connected to a column, the bottom of which is fixedly connected to the top of the base. The column supports the lifting assembly, which helps to maintain the stability of the overall structure during drilling and reduces the impact of vibration on drilling accuracy and equipment life.

[0009] More preferably, the bottom of the base is movably connected to a track, and the track is movably connected to a wheel. The track and wheel can move the device to the location where exploration and detection are required. In geological exploration, it is necessary to move the drilling rig on different terrains to find suitable drilling points. The track can adapt to relatively complex terrains, such as rugged ground and soft ground, which facilitates the transfer of the drilling rig between different locations.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] In this invention, by setting up a fixing component, the hydraulic plug connected to the inside of the hydraulic cylinder drives the fixing cone to move downward and insert the fixing cone into the ground. This makes the device more stable, prevents the drilling rig from shifting during drilling, and can also effectively prevent the device from overturning due to the reaction force of the soil layer on the device during operation, thus ensuring the stability of the drilling rig.

[0012] In this invention, the down-drilling assembly can drill in both forward and reverse directions. When drilling in the forward direction, the drill bit moves downward to carry out normal drilling operations, penetrate deep into the strata to obtain samples or explore the stratum structure. When drilling in the reverse direction, the drill bit can be withdrawn to bring the soil out of the strata and clean up debris. It can also attempt to release the stuck drill bit when it gets stuck, thus improving the practicality of the drilling rig and its ability to cope with complex geological conditions.

[0020] The technical solutions of the embodiments 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please refer to Figures 1-6. This invention provides a technical solution: a forward and reverse drilling rig for geological exploration, including a base 1, which is the basic support structure of the entire drilling rig. A fixing component 6 is installed inside the base 1, including a hydraulic cylinder 601 fixedly connected inside the base 1. A hydraulic plug 602 is movably connected inside the hydraulic cylinder 601, and a fixing cone 603 is fixedly connected to one end of the hydraulic plug 602. Activating the fixing component 6 causes the hydraulic plug 602 to drive the fixing cone 603 downwards, inserting the fixing cone into the ground. This makes the device more stable, preventing displacement of the drilling rig during drilling and avoiding overturning due to the reaction force of the soil layer during operation, thus ensuring the stability of the drilling rig. A lowering drilling component 2 is installed on the top of the base 1, including a motor 201. A rotating shaft 209 is movably connected inside the motor 201, and the side surface of the rotating shaft 209... A bevel gear 202 is fixedly connected, and a bevel gear 203 meshes with one side of the bevel gear 202. A drill rod 204 is fixedly connected to the bottom of the bevel gear 203, and a drill bit 206 is fixedly connected to the bottom of the drill rod 204. A drill blade 205 is fixedly connected to the side surface of the drill rod 204. When the motor 201 is started, the rotating shaft 209 drives the bevel gear 202 to rotate, which in turn drives the bevel gear 203 meshing with the bevel gear 202 to rotate. This causes the drill rod 204, which is fixedly connected to the bottom of the bevel gear 203, to drive the drill blade 205 to drill down into the ground, to obtain samples or explore the geological structure. When the drill rod 204 descends to the designated position, the two motors rotate in opposite directions, causing the drill rod 204 to rise, withdraw the drill bit, and bring the soil out of the strata for cleaning up debris, thus completing the geological exploration. It can also be used to try to release the drill when it gets stuck, improving the practicality of the drilling rig and its ability to cope with complex geological conditions.

[0022] In this embodiment, as shown in Figures 3 and 4, a lifting block 207 is fixedly connected to the bottom of the motor 201, and a fixing plate 208 is fixedly connected to one end of the motor 201 by bolts. The fixing plate 208 is fixedly connected to the top of the lifting block 207, and the drill rod 204 is movably connected inside the lifting block 207.

[0023] In this embodiment, as shown in Figures 2, 3, 4, and 5, a lifting assembly 3 is provided on one side of the lifting block 207. The lifting assembly 3 includes a threaded rod 305, which is movably connected inside the lifting block 207. One end of the threaded rod 305 is fixedly connected to a transmission wheel 302. A rotating shaft 307 is fixedly connected inside the transmission wheel 302. One end of the rotating shaft 307 is movably connected to a motor 301. A transmission belt 303 is movably connected to the side surface of the transmission wheel 302. A transmission wheel 304 is movably connected to the side of the transmission belt 303 away from the transmission wheel 302. A threaded rod 306 is fixedly connected inside the transmission wheel 304. When the motor 301 is started, the rotating shaft 307 rotates, which in turn drives the transmission wheel 302 to rotate, causing the threaded rod 305 fixedly connected to the bottom of the transmission wheel 302 to rotate. At the same time, the transmission belt 303 drives the transmission wheel 304 to rotate, causing the threaded rod 306 fixedly connected to the bottom of the transmission wheel 304 to also rotate. This causes the lifting block 207, which is connected to the side surfaces of the threaded rod 305 and the threaded rod 306, to move the drill rod 204 downward until the drill bit 206 inserts into the ground.

[0024] In this embodiment, as shown in Figures 1, 2, 3 and 6, the side surface of the threaded rod 305 is movably connected to the placement platform 5, and the threaded rod 305 passes through the placement platform 5.

[0025] In this embodiment, as shown in Figures 1, 2 and 4, a column 4 is fixedly connected to the bottom of the platform 5. The bottom of the column 4 is fixedly connected to the top of the base 1. The column 4 supports the lifting assembly 3, which helps to maintain the stability of the overall structure during drilling and reduces the impact of vibration on drilling accuracy and equipment life.

[0026] In this embodiment, as shown in Figures 1, 2 and 4, the bottom of the base 1 is movably connected to the track 7, and the track 7 is movably connected to the track wheel 701. The track 7 and the track wheel 701 can move the device to the location where exploration and detection are required. In geological exploration, it is necessary to move the drilling rig on different terrains to find suitable drilling points. The track 7 can adapt to relatively complex terrains, such as rugged ground and soft ground, which facilitates the transfer of the drilling rig between different locations.

[0027] The method of use and advantages of this invention: The forward and reverse drilling rig for geological exploration operates as follows:

[0028] As shown in Figures 1, 2, 3, 4, 5, and 6, during operation, the device is moved to the location requiring exploration and detection via the traveling tracks 7 and track wheels 701. In geological exploration, the drilling rig needs to be moved across different terrains to find suitable drilling points. The traveling tracks 7 can adapt to complex terrains, such as rugged and soft ground, facilitating the transfer of the drilling rig between different locations. Then, the fixing assembly 6 is activated, causing the hydraulic plug 602 to move the fixing cone 603 downwards, inserting the fixing cone into the ground. This makes the device more stable, preventing displacement of the drilling rig during drilling and avoiding tipping due to the reaction force of the soil layer, ensuring the stability of the drilling rig. Next, the motor 301 is started, causing the rotating shaft 307 to rotate, which in turn drives the transmission wheel 302 to rotate, causing the threaded rod 305 fixedly connected to the bottom of the transmission wheel 302 to rotate. Simultaneously, the transmission belt 30... 3. The transmission wheel 304 rotates, causing the threaded rod 306 fixedly connected to the bottom of the transmission wheel 304 to also rotate. This causes the lifting block 207, which is connected to the side surfaces of the threaded rod 305 and the threaded rod 306, to move the drill rod 204 downwards until the drill bit 206 inserts into the ground. The motor 201 is then started, causing the rotating shaft 209 to drive the bevel gear 202 to rotate. At the same time, the bevel gear 203 meshing with the bevel gear 202 rotates, causing the drill rod 204 fixedly connected to the bottom of the bevel gear 203 to drive the drill bit 205 to drill down into the ground, obtaining samples or probing the geological structure. When the drill rod 204 descends to the designated position, the two motors rotate in opposite directions, causing the drill rod 204 to rise, withdrawing the drill bit, bringing the soil out of the strata, and cleaning up debris to complete the geological exploration. It can also be used to try to release the drill bit when it gets stuck, improving the practicality of the drilling rig and its ability to cope with complex geological conditions.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
