Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically a hydraulic and environmental geological drilling equipment. Background Technology

[0002] Geological drilling is an investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It is a work of investigating and researching the geological conditions of rocks, strata, structures, minerals, hydrology, and landforms in a certain area.

[0003] Modern hydrogeological drilling equipment typically involves fixing the drilling equipment to the ground using a support frame. Due to the complex and varied external geological environment, uneven rock strata or mountains are frequently encountered. Therefore, the angle of the drilling equipment needs to be adjusted according to the angle of the rock strata or mountains. Once the angle is adjusted, the drilling equipment receives the reaction force from the rock strata or mountains, which is then transmitted to the support frame. Since the angle of the support frame cannot be adjusted, uneven force distribution can easily lead to tilting problems. Summary of the Invention

There are two third transmission gears, which are symmetrically distributed on both sides of the fixed frame and connected to each other through a transmission assembly. The internal components of the second adjustable support assembly and the first adjustable support assembly are identical.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Please see Figures 1 to 5 This embodiment provides a hydrogeological drilling device, including a fixed frame 1 and a drilling device 2. The drilling device 2 is rotatably connected to the fixed frame 1 via a first rotating shaft 3. A first synchronous pulley 6 is installed at the end of the first rotating shaft 3. A first transmission rod 101 is also installed on the fixed frame 1. A third transmission gear 10 is installed at one end of the first transmission rod 101. The third transmission gear 10 is connected to the first synchronous pulley 6. A first adjustable support assembly 13 is also installed on the fixed frame 1. A first eccentric column 11 is installed on the third transmission gear 10 at a position away from the center. The first adjustable support assembly 13 includes a frame 131, a second rotating shaft 132, and a sliding rod 133. The frame 131 has a cavity 134 and an air inlet pipe 135. A second rotating shaft 132 is installed on the end of the frame 131 near the drilling equipment 2. The second rotating shaft 132 is rotatably connected to the fixed frame 1. The frame 131 has a cavity 134. The slide rod 133 is inserted into the cavity 134. The frame 131 has an air inlet pipe 135 that communicates with the cavity 134. A first connecting rod 12 is hinged between the first eccentric column 11 and the frame 131. A first transmission gear 4 is also installed on the end of the first rotating shaft 3 away from the first synchronous wheel 6. A drive gear 5 that meshes with the first transmission gear 6 is also installed on the fixed frame 1. A hand crank 51 is installed on the drive gear 5.

[0023] In the above scheme, when the angle of the drilled terrain changes, manually cranking the hand crank 51 drives the drive gear 5, the first transmission gear 4, the first rotating shaft 3, and the drilling equipment 2 to rotate by a certain angle. The rotating first rotating shaft 3 can also drive the third transmission gear 10 to rotate by a certain angle. The rotating third transmission gear 10, in turn, drives the first adjustable support assembly 13 to rotate by a certain angle away from the fixed frame 1 through the first connecting rod 12. At this time, the slide rod 133 in the first adjustable support assembly 13 can slide a certain distance towards the ground in the cavity 134 on the frame 131 until the slide rod 133 contacts the ground and stops. This can enhance the stability of the device. Compared with the non-adjustable fixed frame 1, the angle of the first adjustable support assembly 13 can change with the angle of the drilling equipment 2, and has the characteristics of good adjustability and good stability. This solves the problem of poor stability of existing hydrogeological drilling equipment.

[0024] Please see Figures 1 to 5 As one embodiment of this application, a second adjustable support assembly 16 is also hinged to the fixed frame 1. The second adjustable support assembly 16 and the first adjustable support assembly 13 are symmetrically distributed on both sides of the fixed frame 1. There are two third transmission gears 10, which are symmetrically distributed on both sides of the fixed frame 1 and connected to each other by a transmission assembly 18. The internal components of the second adjustable support assembly 16 and the first adjustable support assembly 13 are identical. The second adjustable support assembly 16 is connected to the other of the two third transmission gears 10 through a second connecting rod 15. The air inlet pipes 135 in the first adjustable support assembly 13 and the second adjustable support assembly 16 are respectively connected to gas through a first air guide pipe 14 and a second air guide pipe 17. The conveying mechanism 19 includes a second transmission gear 8 mounted on the fixed frame 1. The second transmission gear 8 meshes with a third transmission gear 10. A second synchronous pulley 9 is coaxially connected to the second transmission gear 8. A synchronous belt 7 connects the first synchronous pulley 6 and the second synchronous pulley 9. A fourth transmission gear 102 is also mounted on the first transmission rod 101 connected to the two third transmission gears 10. The transmission assembly 18 includes a fifth transmission gear 181, a second transmission rod 182, and a sixth transmission gear 183. The fifth transmission gear 181 and the sixth transmission gear 183 are both mounted on the second transmission rod 182. The second transmission rod 182 is rotatably connected to the fixed frame 1. The fifth transmission gear 181 and the sixth transmission gear 183 are meshed with the fourth transmission gear 102.

[0025] In the above scheme, the design of the transmission component 18 enables the two third transmission gears 10 to have the same direction of rotation and speed. Thus, when the drilling equipment 2 rotates towards the second adjustable support component 16 (referring to the direction of the drill rod), the third transmission gear 10 connected to it can drive the second adjustable support component 16 to rotate towards the fixed frame 1 via the second connecting rod 15. Meanwhile, the other third transmission gear 10 can drive the first adjustable support component 13 to rotate away from the fixed frame 1 via the first connecting rod 12. When the drilling equipment 2 rotates away from the second adjustable support component 16 (referring to the direction of the drill rod), the principle is the same as above. When the drill rod drills into geological rock formations in a certain direction, the reaction force during drilling is in the opposite direction. Therefore, a support component should be installed in the opposite direction; otherwise, the drilling equipment 2 will easily tilt. For example, the first adjustable support component 13 and the second adjustable support component 16 mentioned above change according to the drilling angle of the drilling equipment 2, ultimately providing support and exhibiting good stability and practicality.

[0026] Please see Figures 1 to 5 As one embodiment of this application, the gas delivery mechanism 19 includes a pressurizing assembly 191 and a housing assembly 192. The pressurizing assembly 191 includes a rotating wheel 1911, a second eccentric column 1912, a third connecting rod 1913, and a first piston 1914. The rotating wheel 1911 is mounted on the first transmission rod 101 at one end away from the third transmission gear 10. The second eccentric column 1912 is mounted on the rotating wheel 1911 at a position away from the center. The first piston 1914 is mounted inside the housing assembly 192. The third connecting rod 1913 is hinged between the second eccentric column 1912 and the first piston 1914. The housing assembly 192 includes a first sealing cavity 1921, a second sealing cavity 1922, a first gas outlet pipe 1923, a connecting pipe 1924, a second piston 1925, and a second gas outlet pipe 1926. The first sealing cavity 1921... A connecting pipe 1924 is installed between the first piston 1914 and the second sealing cavity 1922. The first piston 1914 is fitted to the inner wall of the first sealing cavity 1921, and the second piston 1925 is fitted to the inner wall of the second sealing cavity 1922. A first vent pipe 1923 and a second vent pipe 1926 are respectively installed on the first sealing cavity 1921 and the second sealing cavity 1922. A first air guide pipe 14 and a second air guide pipe 17 are respectively connected to the first vent pipe 1923 and the second vent pipe 1926. The connecting pipe 1924 is positioned higher than the first piston 1924 and lower than the second piston 1925. The first vent pipe 1923 is lower than the first piston 1914, and the second vent pipe 1926 is higher than the second piston 1925.

[0027] In the above scheme, while the drilling equipment 2 rotates to adjust the angle, it can also drive the rotating wheel 1911 to rotate. This, in turn, drives the first piston 1914 to reciprocate linearly within the first sealed cavity 1921 via the second eccentric column 1912 and the third connecting rod 1913, thereby compressing the gas. The gas in the first sealed cavity 1921 is compressed into the second sealed cavity 1922 and the cavity 134 in the first adjustable support assembly 13 through the connecting pipe 1924 and the first vent pipe 1923. The gas entering the second sealed cavity 1922 then pushes the second piston 1925 to move. The second piston 1925 then compresses the gas in the second sealed cavity 1922 into the cavity 134 in the second adjustable support assembly 16 through the second vent pipe 1926. The gas entering the cavity 134 then pushes the sliding rod 133 to slide. Ultimately, this achieves the function of adjusting both the angle and length of the first adjustable support assembly 13, possessing the characteristics of good adjustability, good stability, and strong practicality.

[0028] In use, manually cranking the hand crank 51 drives the drive gear 5, the first transmission gear 4, the first rotating shaft 3, and the drilling equipment 2 to rotate at a certain angle. The rotating first rotating shaft 3 can also drive the third transmission gear 10 to rotate at a certain angle. When the drilling equipment 2 rotates towards the second adjustable support assembly 16 (referring to the orientation of the drill rod), the third transmission gear 10 connected to it can drive the second adjustable support assembly 16 to rotate towards the fixed frame 1 via the second connecting rod 15. Meanwhile, the other third transmission gear 10 can drive the first adjustable support assembly 13 to rotate away from the fixed frame 1 via the first connecting rod 12. When the drilling equipment 2 rotates away from the second adjustable support assembly 16 (referring to the orientation of the drill rod), the principle is the same as described above. While rotating to adjust the angle, the drilling equipment 2 can also drive the rotating wheel. Rotation of 1911, in turn, drives the first piston 1914 to reciprocate linearly within the first sealed cavity 1921 via the second eccentric column 1912 and the third connecting rod 1913, thereby compressing the gas. This compresses the gas within the first sealed cavity 1921 into the second sealed cavity 1922 and the cavity 134 within the first adjustable support assembly 13 through the connecting pipe 1924 and the first vent pipe 1923. The gas entering the second sealed cavity 1922 then pushes the second piston 1925 to move. The second piston 1925 then compresses the gas within the second sealed cavity 1922 into the cavity 134 within the second adjustable support assembly 16 through the second vent pipe 1926. The gas entering the cavity 134 then pushes the sliding rod 133 to slide, ultimately achieving the function of adjusting both the angle and length of the first adjustable support assembly 13.

[0029] In summary, the rotating first shaft 3 can also drive the third transmission gear 10 to rotate at a certain angle. The rotating third transmission gear 10, in turn, drives the first adjustable support assembly 13 to rotate at a certain angle away from the fixed frame 1 via the first connecting rod 12. At this time, the slide rod 133 in the first adjustable support assembly 13 can slide a certain distance towards the ground within the cavity 134 on the frame 131 until it stops when it contacts the ground. This enhances the stability of the device. Compared to the non-adjustable fixed frame 1, the angle of the first adjustable support assembly 13 can change with the angle of the drilling equipment 2, possessing the characteristics of good adjustability and good stability. This solves the problem of poor stability in existing hydrogeological drilling equipment.
