Description

Technical Field

[0001] This utility model relates to the field of rapid assembly technology for portable drilling rigs, and in particular to a rapid assembly structure for portable drilling rigs used in geological exploration. Background Technology

[0002] A portable drilling rig for geological exploration is a device used in geological exploration work to obtain underground rock core samples. Its function is to extract deep underground rocks through drilling operations in different geological environments, so that geologists can analyze them to understand important information about underground geological structures and mineral resource distribution. In field exploration scenarios, portable drilling rigs need to have the characteristics of rapid transfer and assembly, adapt to complex and changing terrain conditions, and improve the efficiency of exploration work.

[0003] In existing portable drilling rig technologies for geological exploration, the assembly structure usually adopts a traditional method, which commonly involves splicing together multiple scattered parts and fixing them with bolts and nuts. This method can achieve the assembly of the drilling rig to a certain extent and enable it to operate normally in a stable working environment.

[0004] The existing rapid assembly structure of portable drilling rigs has many problems. The existing portable drilling rigs use bolts to fix the scattered parts one by one to avoid loosening of the parts during transportation and ensure the integrity of the parts during transportation. However, during the assembly process, the workers need to manually operate wrenches to tighten a large number of bolts and nuts one by one. The operation is extremely cumbersome and time-consuming. In the complex field environment, especially in mountainous and jungle terrain, the space for workers to operate is limited, and it is even more difficult to tighten bolts and nuts with tools. This leads to low assembly efficiency, affects the stability of the component connection, reduces the reliability of the drilling rig during operation, and fails to meet the geological exploration requirements for rapid and efficient operation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a portable geological exploration drilling rig quick assembly structure, including a base 1. The base 1 supports and stabilizes the entire drilling rig structure, providing a basic platform for the components. Telescopic rods 3 are fixedly connected to the four corners of the top of the base 1. The height of the telescopic rods 3 is adjustable. The tops of multiple telescopic rods 3 are fixedly connected to the same fixing plate 4, ensuring the stability of the device installation. A hydraulic actuator 5 is fixedly connected to the top of the fixing plate 4, providing power for the extension and retraction of hydraulic rods 6. The bottom of the hydraulic actuator 5 penetrates the interior of the fixing plate 4 and is fixedly connected to the top of the hydraulic rods 6. The hydraulic rods 6 drive a lower movable plate 7 to move up and down. The bottom of the hydraulic rods 6 is fixedly connected to the movable plate 7, which slides on the outer wall of the telescopic rods 3 to ensure stability during movement. The four corners of the movable plate 7 are slidably connected to the outer wall of the telescopic rods 3, making the movement of the movable plate 7 more stable and ensuring accuracy during operation. Support rods 8 are threadedly connected to the front and rear sides of the bottom of the movable plate 7. 8. To improve stability during drilling, both support rods 8 are threadedly connected to a press 9 at their bottom. The press 9 provides downward impact force to assist the drill rod 10 in its work, improving efficiency. The bottom of the press 9 is rotatably connected to the drill rod 10. The drill rod 10 rotates and is pressed down under the action of the press 9 to achieve geological drilling and sample acquisition. The bottom of the drill rod 10 is rotatably connected to a quick-connect coupling 11, which facilitates quick replacement of different types of drill bits, improving work efficiency. The top front of the base 1 is slidably connected to a rod receiving box 12, which is used to store multiple drill pipes 13, making it convenient to add drill pipes 13 during drilling. The rod receiving box 12 is equipped with multiple drill pipes 13 inside, which are connected to the drill rod 10 to extend the drilling depth and meet different exploration needs. The top rear of the base 1 is equipped with a dust extraction mechanism 2, which is used to reduce flying dust, reduce the impact of dust generated during drilling on the environment and operators, improve work efficiency, and improve the working environment.

[0033] Specifically, the base 1 is placed at the predetermined exploration location. Based on the terrain and actual needs of the exploration site, the height of the telescopic rods 3 at the four corners of the top of the base 1 is adjusted to ensure the drilling rig is horizontally stable during operation. After adjustment, the tops of multiple telescopic rods 3 are jointly supported and fixedly connected to the same fixed plate 4. The hydraulic actuator 5 connected to the top of the fixed plate 4 begins to operate, providing power for the extension and retraction of the hydraulic rods 6. When the hydraulic actuator 5 starts, the hydraulic oil is pressurized and pushed. Under the push of the hydraulic rods 6, the moving plate 7 slides downwards along the outer wall of the telescopic rods 3. As the moving plate 7 descends, the support rods 8 connected to the front and rear sides of the bottom of the moving plate 7 also descend accordingly. When drilling begins, the bottom of the support rods 8 contacts the ground and provides support, improving the overall stability of the drilling rig during drilling. The presses 9 connected to the bottom of the two support rods 8 also begin to operate, providing downward impact force for the drilling of the drill rod 10. The presses 9 utilize their own power unit to generate a powerful impact force that is transmitted to the rotating drill rod 10 below, assisting the drill rod 10 in overcoming... Geological resistance improves drilling efficiency. Under the action of the press 9, the drill rod 10 rotates and is subjected to downward pressure to drill into the geology and obtain geological samples. The quick-connect coupling 11 connected to the bottom of the drill rod 10 plays a role in the process. When it is necessary to change different types of drill bits to adapt to different geological conditions, the quick-connect coupling 11 can quickly and conveniently change the drill bits, which greatly improves work efficiency. During the drilling process, it is necessary to further extend the drilling depth to meet different exploration needs. Take out the multiple drill pipes 13 stored in the rod connection box 12. The operator takes out the drill pipes 13 from the rod connection box 12 and connects them to the drill rod 10, which increases the total length of the drill rod 10 and enables deeper geological drilling. The dust extraction mechanism 2 on the top rear side of the base 1 works continuously throughout the drilling process. The drilling process generates a lot of dust. The dust extraction mechanism 2 sucks in and treats the flying dust generated by drilling through its own dust collection device, reducing the pollution of flying dust to the environment, reducing the impact of dust on the health of operators, and improving work efficiency and the overall working environment.

[0034] Reference Figure 1 , Figure 2 and Figure 4The dust extraction mechanism 2 of the portable geological exploration drilling rig includes a fan 201, which generates suction to achieve the dust extraction function. The fan 201 is slidably connected to the top rear side of the base 1, allowing the fan 201 to be flexibly adjusted in position as needed. An air inlet pipe 202 is fixedly connected to the middle of the front side of the fan 201, guiding dust into the fan 201. A filter screen 203 is rotatably connected to the inner wall of the front side of the air inlet pipe 202, filtering out large particles of impurities in the dust and preventing them from entering the air. The intake fan 201 is damaged. A radiator 204 is fixedly connected to the right side of the fan 201. The radiator 204 can dissipate heat when the fan 201 is working and ensure the stable operation of the fan 201. A connector 205 is fixedly connected to the middle of the left side of the fan 201. The connector 205 can connect and replace the exhaust pipes 206 of different lengths to realize the connection between components. The exhaust pipe 206 is rotatably connected to the inner wall of the connector 205. The exhaust pipe 206 is used to discharge the treated air and dust.

[0035] Specifically, when the dust extraction mechanism 2 of the portable geological exploration drilling rig is working, the fan 201 starts, generating a strong suction to initiate the dust extraction process. The bottom of the fan 201 is slidably connected to the top rear side of the base 1, allowing for flexible position adjustment to ensure precise alignment with the dust outlet. The air intake pipe 202 connected to the front center of the fan 201 guides dust-laden air into the fan 201 under the suction. The filter screen 203 connected to the inner wall of the front side of the air intake pipe 202 intercepts and filters large particles of dust, preventing them from entering the fan 201 and effectively preventing dust accumulation inside the fan 201 due to large particles. Impurities wear and tear, and the fan 201 generates heat during operation. The radiator 204 connected on the right continuously dissipates heat from the fan 201, ensuring stable operation and maintaining stable suction. The treated air and dust flow to the exhaust pipe 206 through the connector 205 connected to the middle of the left side of the fan 201. The inner wall of the connector 205 is connected to the exhaust pipe 206. The exhaust pipe 206 can be connected and replaced with different lengths according to actual needs to achieve flexible connection between components. The exhaust pipe 206 discharges the treated air and dust, completing the entire dust extraction process.

[0036] Reference Figure 1 , Figure 3 and Figure 5A slide groove 14 is fixedly connected to the far side of the fan 201. The slide groove 14 provides a sliding track for the positioning pin 15, realizing the limit and positioning functions. The positioning pin 15 is slidably connected inside the left slide groove 14. The positioning pin 15 can slide in the slide groove 14 to play a role in precise positioning. Multiple fixing blocks 16 are fixedly connected to the front and rear sides of the left side of the press 9. The fixing blocks 16 enhance the stability of the overall structure. Two slide grooves 21 are fixedly connected to the front and rear sides of the bottom of the base 1. The slide grooves 21 provide sliding space for the conical slider 22 to facilitate specific sliding operations. The two front slide grooves 21 and the two rear slide grooves 21 are connected to each other. Conical sliders 22 are slidably connected between adjacent parts. The conical sliders 22 slide within the second groove 21. The conical shape can provide fixed support on soft ground. Protective pads 23 are fixedly connected around the bottom of the outer wall of the hydraulic unit 5. The protective pads 23 can effectively protect the bottom of the hydraulic unit 5 and reduce wear and external damage. Fixing screws 24 are rotatably connected at the four corners of the protective pads 23. The fixing screws 24 are used to firmly fix the protective pads 23 to the outer wall of the hydraulic unit 5. The bottom of the multiple fixing screws 24 penetrates the interior of the protective pads 23 and is threaded to the top of the fixing plate 4. The protective pads 23 and the fixing plate 4 are firmly fixed through the threaded connection.

[0037] Specifically, slide groove 14 serves as a limiting and positioning mechanism. Positioning pin 15 slides within slide groove 14, which provides a sliding track for the positioning pin 15, achieving precise limiting and positioning functions. This ensures the accuracy and stability of the fan 201's position during operation. Multiple fixing blocks 16 are connected to the front and rear sides of the left side of the press 9. These fixing blocks 16 effectively enhance the overall structural stability of the press 9, ensuring its smooth operation. Two slide grooves 21 are connected to the front and rear sides of the bottom of the base 1. Conical sliders 22 are connected between adjacent sections of the two front and two rear slide grooves 21. Slide grooves 21 provide sliding space for the conical sliders 22. To achieve the sliding adjustment operation, when the device is placed on soft ground, the conical slider 22 can slide within the slide groove 21, using its conical structure to provide fixed support and enhance the overall stability of the device. The bottom of the outer wall of the hydraulic unit 5 is connected with a protective pad 23, which can effectively protect the bottom of the hydraulic unit 5 and reduce wear and external damage. Each of the four corners of the protective pad 23 is connected with a fixing screw 24. The bottom of the multiple fixing screws 24 penetrates the interior of the protective pad 23 and is connected to the top of the fixing plate 4. The protective pad 23 is firmly fixed to the fixing plate 4 through a stable threaded connection, ensuring that the protective pad 23 can stably provide protection for the hydraulic unit 5.

[0038] Reference Figure 1 , Figure 2 and Figure 5Each of the two front and two rear fixed blocks 16 is threaded with an auxiliary rod 18, which enhances the connection stability between the fixed blocks 16 and makes the overall structure sturdy. Each of the two front and two rear fixed blocks 16 is rotatably connected with two fixing bolts 17. The outer walls of the multiple fixing bolts 17 penetrate the interior of the auxiliary rods 18, and the auxiliary rods 18 are tightly connected to the fixed blocks 16 through the fixing bolts 17 to ensure the reliability of the connection. Each of the two auxiliary rods 18 is rotatably connected with a handle 19 on the left side, which facilitates the user to perform auxiliary operation on the press 9. The outer walls of the handles 19 are fixedly connected with rubber sleeves 20 on the front and rear sides. The rubber sleeves 20 can provide a better grip, increase friction, and prevent slippage during operation.

[0039] Specifically, the two front fixing blocks 16 and the two rear fixing blocks 16 provide basic support and connection. Auxiliary rods 18 are connected between adjacent fixing blocks 16, which enhances the connection stability between the fixing blocks 16 and makes the overall structure more robust. Two fixing bolts 17 are connected inside the two front fixing blocks 16 and the two rear fixing blocks 16. The outer walls of the multiple fixing bolts 17 penetrate the interior of the auxiliary rods 18. By tightening the fixing bolts 17, the auxiliary rods 18 and the fixing blocks 16 can be tightly connected to ensure the reliability of the connection. When auxiliary operation of the stamping machine 9 is required, the user can hold the handle 19 connected between the two adjacent auxiliary rods 18 on the left side. The rubber sleeves 20 connected to the front and rear sides of the outer wall of the handle 19 can provide a better grip, increase friction, prevent slippage during operation, and help the user to carry out auxiliary operation of the stamping machine 9 more conveniently and stably, ensuring the smooth operation of the stamping work.

[0040] Working Principle: The base 1 is placed at the predetermined exploration location. Based on the terrain and actual needs of the exploration site, the height of the telescopic rods 3 at the four corners of the top of the base 1 is adjusted to ensure the drilling rig is horizontally stable during operation. After adjustment, the hydraulic actuator 5 on the top of the fixed plate 4 begins operation, providing power for the extension and retraction of the hydraulic rods 6. When the hydraulic actuator 5 is activated, the hydraulic oil is pressurized and pushed. Under the push of the hydraulic rods 6, the moving plate 7 slides downwards along the outer wall of the telescopic rods 3. As the moving plate 7 descends, when drilling begins, the bottom of the support rod 8 contacts the ground and provides support, improving the overall stability of the drilling rig during drilling. The press 9 generates a powerful impact force that is transmitted downwards. The rotating drill rod 10 helps overcome geological resistance and improve drilling efficiency. Under the action of the press 9, the drill rod 10 rotates and is subjected to downward pressure to drill into the geology and obtain geological samples. When it is necessary to change different types of drill bits to adapt to different geological conditions, the quick-connect coupling 11 can quickly and conveniently change the drill bits, which greatly improves work efficiency. During the drilling process, if it is necessary to further extend the drilling depth to meet different exploration needs, take out the multiple drill pipes 13 stored in the connecting rod box 12. The operator takes out the drill pipes 13 in the connecting rod box 12 and connects them to the drill rod 10, which increases the total length of the drill rod 10 and enables deeper geological drilling.

[0041] When the dust extraction mechanism 2 of the portable geological exploration drilling rig is working, the fan 201 starts, generating a strong suction to initiate the dust extraction process. The fan 201 can be flexibly adjusted within the partition on the base 1 to ensure precise alignment with the dust extraction location. The air intake pipe 202 connected to the front center of the fan 201 guides dust-laden air into the fan 201 under the action of suction. The filter screen 203 on the front side of the air intake pipe 202 intercepts and filters large particles of impurities in the dust, preventing them from entering the fan 201 and effectively avoiding damage to the inside of the fan 201 due to wear caused by large particles of impurities. The working process of the fan 201... The heat generated during operation is discharged through radiator 204, continuously cooling the fan 201, ensuring stable operation of the fan 201, and maintaining stable suction. The treated air and dust flow to the exhaust pipe 206 through connector 205. The inner wall of connector 205 is connected to the exhaust pipe 206. Exhaust pipes 206 of different lengths can be connected and replaced according to actual needs to achieve flexible connection between components. The exhaust pipe 206 discharges the treated air and dust, reducing dust pollution to the environment, reducing the impact of dust on the health of operators, and improving work efficiency and the overall working environment.
