Description

Technical Field

[0001] The present invention relates to the field of geological exploration, in particular to a mining geological exploration drilling sampling device. Background Art

[0002] A drilling sampling device is a device specially used in geological exploration, mineral resource exploration and other fields. Its core function is to obtain underground rock, soil or lava samples through drilling for subsequent geological analysis, mineral evaluation or radiochemical analysis.

[0003] Drilling and sampling equipment used for mine geological exploration typically includes a drill rig, a drill rod, and a lifting mechanism. During the drilling process, the drill rig drives the drill rod to rotate, and the lifting mechanism drives the drill rig to descend, allowing the drill rod to drill downward. During the drilling process, rock or soil is gradually cut and falls into a sampler inside the drill rod. When the predetermined drilling depth or sampling volume is reached, drilling is stopped and the lifting mechanism drives the drill rig to rise, thereby removing the drill rod and the sampler inside the drill rod. After analyzing the rock or soil in the sampler, the mine geological exploration is completed.

[0004] The lifting mechanism for lifting the drilling rig usually uses a vertically set linear module to directly drive the motor. During the process of removing the drill rod after drilling, the drill rod is prone to fall off or breakage due to stress concentration, which is inconvenient and makes it difficult to ensure the safety and stability of the drill rod when it is removed.

[0008] By adopting the above technical solution, during drilling and sampling, the drilling mount is first clamped by the clamping assembly to achieve fixation between the first lifting mount and the drilling mount, and then the drill rig drives the rotation of the drill rod and the first linear module drives the movement of its own slider to achieve downward drilling of the drill rod; after reaching the predetermined drilling depth or sampling volume, the clamping assembly is released from the drilling mount, and then the fixed driving assembly drives each fixing rod to move toward the axis of the fixing ring so that each fixing rod can achieve a tight fixation on the drill rod, and then the second linear module drives the movement of its own slider in sections to pull the drill rod out of the drilling area, thereby finally achieving the removal of the entire drill rod; after each fixing rod clamps the drill rod and then removes the drill rod through multiple vertical movements, it helps to reduce shaking and deviation during the removal of the drill rod, thereby improving drilling efficiency and ensuring the stability and accuracy of the drill rod during the removal process. In addition, by clamping different parts of the drill rod multiple times, it can better adapt to changes in different strata and rock types, ensure the smooth progress of the drilling process, and reduce drilling accidents and losses caused by changes in geological conditions.

[0012] By adopting the above technical solution, when the fixed motor drives its own output end to rotate, the transmission worm drives the transmission worm wheel and the transmission gear to move synchronously, and finally drives the fixed drive ring to rotate. The self-locking effect between the transmission worm wheel and the transmission worm is conducive to ensuring the stability of the position of the fixed drive ring after it finally drives the fixed rods to move.

[0016] By adopting the above technical solution, the setting of the fixing spring enables the first fixing part to have a stroke amount that moves along the radial direction of the fixing ring, so that the first fixing part plays an elastic buffering role during the drilling and sampling of the drill rod, which facilitates the correction of the drill rod during the drilling process and ensures the stability and work efficiency of the drill rod during drilling.

[0021] Optionally, a pressing roller is rotatably mounted on one end of each of the first fixing portions facing the axis of the fixing ring.

[0022] By adopting the above technical solution, the setting of the pressure roller ensures that the friction between the drill rod and the end of the first fixed part during the rotation and drilling of the drill rod is rolling friction, so that the first fixed part is not prone to wear caused by friction with the drill rod when guiding and correcting the drill rod, which is beneficial to ensuring the service life of the fixed rod.

[0023] Optionally, the fixing ring is fixedly mounted with a plurality of fixing guide rails which are arranged in one-to-one correspondence with the fixing rods and extend along the radial direction of the fixing ring.

The clamping motor is used to drive the bidirectional clamping screw to rotate. The drilling mounting seat is provided with positioning grooves on both sides in the horizontal direction for plugging and engaging with the two clamping rods.

[0026] By adopting the above technical solution, when the two clamping rods are located at the same horizontal line as the two clamping grooves, the bidirectional clamping screw is driven to rotate by the clamping motor, and the two clamping rods are matched with the threads of the bidirectional clamping screw and move toward or away from each other under the limiting action of the clamping slide groove.

[0028] 1. Each fixing rod clamps the drill rod and then removes the drill rod through multiple vertical movements, which helps to reduce the shaking and deviation during the removal of the drill rod, thereby improving the drilling efficiency and ensuring the stability and accuracy of the drill rod during the removal process.

[0029] 2. The provision of two sets of fixing rods allows each drill rod to be limited in more positions when clamped and fixed by the fixing rods, thereby further ensuring the clamping stability of each fixing rod when clamping the drill rod and thus removing the drill rod.

[0038] The present application discloses a mining geological exploration drilling sampling device. Figure 1 The mining geological exploration drilling and sampling device includes a drilling mechanism and a lifting mechanism, wherein the drilling mechanism includes a drill rod 1, a drill rig 2 and a drilling mounting seat 3.

[0039] Reference Figure 1 and Figure 2The lifting mechanism includes a lifting base 4, a first lifting assembly, and a second lifting assembly. A vertical through-hole 5 is provided on the top of the lifting base 4 for the drill rod 1 to pass through. The first lifting assembly includes a first linear module 6 and a first lifting mount 7. The first linear module 6 is vertically mounted on the top of the lifting base 4 and is located near one end of the lifting base 4 in the longitudinal direction. The first lifting mount 7 is fixedly mounted on the slider of the first linear module 6, so that the first linear module 6 drives the first lifting mount 7 to move in the vertical direction.

[0040] Reference Figure 1 The first lifting mount 7 is provided with a clamping assembly, specifically, the clamping assembly includes a clamping rod 8, a bidirectional clamping screw 9 and a clamping motor 10, wherein the first lifting mount 7 is provided with a clamping slot 11 extending in the horizontal direction on the side away from the first linear module 6, and two clamping rods 8 are provided and both slide in the clamping slot 11, and the bidirectional clamping screw 9 is horizontally rotatably installed on the clamping rod 8, and the two ends of the bidirectional clamping screw 9 with opposite threads are respectively passed through and slidably fitted on the two clamping rods 8, and the clamping motor 10 is installed at one end in the length direction of the first lifting mount 7 and is used to drive the bidirectional clamping screw 9 to rotate, so that when the clamping motor 10 drives the bidirectional clamping screw 9 to rotate, the two clamping rods 8 move toward or away from each other along the length direction of the clamping slot 11.

[0041] Continue to refer to Figure 1 , there are clamping grooves 12 on both sides of the drilling mounting seat 3 in the horizontal direction, and the two clamping grooves 12 are respectively plugged into the two clamping rods 8. When the two clamping rods 8 are respectively inserted into the two clamping grooves 12 in the direction of approaching each other, the clamping and fixation between the first lifting mounting seat 7 and the drilling mounting seat 3 are realized, so that it is convenient to drive the vertical movement of its own slider through the first linear module 6 to synchronously realize the downward drilling of the drill rod 1.

[0042] Reference Figure 1 and Figure 2 The second lifting mechanism includes a second linear module 13 and a second lifting mounting seat 14. The second linear module 13 is vertically arranged on the lifting fixed seat 4. The first linear module 6 and the second linear module 13 are respectively arranged near the two ends of the length direction of the lifting fixed seat 4. The second lifting mounting seat 14 is fixedly installed on the slider of the second linear module 13, so that the second linear module 13 drives the second lifting mounting seat 14 to move in the vertical direction.

[0043] Reference Figure 2 and Figure 3The second lifting mount 14 is provided with a fixing mechanism, which includes a fixing ring 15, a fixing rod 16 and a fixed drive assembly, wherein the fixing ring 15 includes a first ring body 151, a second ring body 152 and a connecting rod 153, the first ring body 151 and the second ring body 152 are coaxially arranged, the first ring body 151 is fixedly mounted on the top of the second lifting mount 14, the second ring body 152 is located on the top of the first ring body 151, and the middle parts of the first ring body 151 and the second ring body 152 both have a through hole 17 for the drill rod 1 to pass through.

[0044] Reference Figure 3 and Figure 4 A plurality of connecting rods 153 are evenly distributed circumferentially around the axis of the first ring body 151. In the embodiment of the present application, the number of connecting rods 153 is set to three. One end of each connecting rod 153 is fixedly mounted to the first ring body 151 and the other end is fixedly mounted to the second ring body 152, thereby achieving a stable connection between the first ring body 151 and the second ring body 152. Two groups of fixing rods 16 are provided corresponding to the first ring body 151 and the second ring body 152. The two groups of fixing rods 16 are respectively located on the side close to the first ring body 151 and the second ring body 152. In the embodiment of the present application, each group of fixing rods 16 is evenly distributed around the axis of the fixing ring 15.

[0045] Reference Figure 2 and Figure 3 Specifically, the fixing rod 16 includes a first fixing portion 161, a second fixing portion 162 and a fixing spring 163. Three fixing guide rails 18 are fixedly installed on the side where the first ring body 151 and the second ring body 152 are close to each other, and are arranged one by one in correspondence with the fixing rod 16 and extending along the radial direction of the first ring body 151. In the embodiment of the present application, the cross-section of the fixing guide rail 18 is T-shaped. The fixing guide rail 18 is sequentially inserted into the first fixing portion 161 and the second fixing portion 162 of the fixing rod 16 and slidably cooperates with the first fixing portion 161 and the second fixing portion 162 of the fixing rod 16 to ensure the stability of the first fixing portion 161 and the second fixing portion 162 when moving along the radial direction of the first ring body 151.

[0046] Reference Figure 2The first and second fixing portions 161, 162 are radially arranged from the inside outward along the fixing ring 15. A fixing spring 163 is located between the first and second fixing portions 161, 162. One end of the fixing spring 163 is connected to the first fixing portion 161 and the other end is connected to the second fixing portion 162. This allows the first fixing portion 161 to act as an elastic buffer for the drill rod 1 during drilling and sampling, facilitating deviation correction of the drill rod 1 during drilling, and ensuring stability and efficiency during drilling. Each first fixing portion 161 is rotatably mounted with a pressure roller 19 at one end facing the axis of the fixing ring 15. The axis of the pressure roller 19 is parallel to the axis of the drill rod 1. This ensures that the friction between the drill rod 1 and the end of the first fixing portion 161 during drilling is rolling friction. This reduces the wear of the first fixing portion 161 caused by friction with the drill rod 1 during guidance and correction, and helps to ensure the service life of the first fixing portion 161.

[0047] Continue to refer to Figure 2 The first fixing portion 161 is rotatably installed with an adjusting screw 20 at one end facing the second fixing portion 162. The adjusting screw 20 is passed through the radial direction of the fixing ring 15 and slidably fitted on the second fixing portion 162. The adjusting screw 20 is passed through one end of the first fixing portion 161 and is threadedly fitted with an adjusting nut 21. When the adjusting nut 21 is rotated so that the adjusting nut 21 is fixed in different length directions of the adjusting screw 20, the maximum distance between the first fixing portion 161 and the second fixing portion 162 is adjusted, and finally the elastic force of the fixing spring 163 is accurately adjusted, so that the first fixing portion 161 can be adaptively adjusted according to drilling conditions of different geology, and has strong applicability.

[0048] Reference Figure 2 and Figure 4 Furthermore, the adjusting screw 20 is fixedly installed with a horizontally arranged fixing screw 22, and the second fixing portion 162 is provided with a fixing slot 23 extending along the radial direction of the fixing ring 15 and horizontally passing through. The two ends of the fixing screw 22 are respectively passed through the two notches of the fixing slot 23 and slidably fitted in the fixing slot 23. Both ends of the fixing screw 22 are passed through the outside of the fixing slot 23 and are threadedly fitted with a fixing nut 24. Screwing the fixing nut 24 so that the fixing nut 24 is tightened against the second fixing portion 162 can achieve a firm fixation of the fixing screw 22 and the first fixing portion 161, thereby facilitating the stable clamping of the drill rod 1 during the removal process through the first fixing portion 161.

[0049] Reference Figure 3 and Figure 4The fixed drive assembly is used to drive each fixed rod 16 to move toward or away from the axial direction of the fixed ring 15. Specifically, the fixed drive assembly includes a fixed motor 25, a fixed drive ring 26 and a fixed drive rod 27. The fixed drive ring 26 is coaxially mounted on the top of the second ring body 152. The fixed drive ring 26 is provided with a vertically penetrating avoidance hole 28 for the drill rod 1 to pass through.

[0050] Continue to refer to Figure 3 and Figure 4 The fixed drive rods 27 are vertically arranged and fixedly connected to the second fixing portions 162 of the two fixing rods 16. The top of the second ring body 152 is provided with three fixed drive grooves 29, which correspond to and extend through the fixing rods 16. The fixed drive grooves 29 extend radially along the second ring body 152. One end of each fixed drive rod 27 slides within each fixed drive groove 29. The fixed drive ring 26 is provided with three arcuate drive grooves 30 evenly distributed circumferentially around its axis. One end of each fixed drive rod 27 slides within each arcuate drive groove 30. When the fixed drive ring 26 rotates, the fixed drive rods 27, driven by the arcuate drive grooves 30, drive the fixing rods 16 along the fixed drive grooves 29 toward or away from the axis of the fixing ring 15, thereby facilitating the clamping or unclamping of the drill rod 1 in a convenient and quick manner.

[0051] Continue to refer to Figure 3 and Figure 4 The fixed motor 25 is used to drive the fixed drive ring 26 to rotate. Specifically, the fixed motor 25 is installed on the side of the second ring body 152 facing the first ring body 151. The fixed motor 25 drives the fixed drive ring 26 to rotate through the transmission assembly. The transmission assembly includes a transmission worm 31, a transmission worm wheel 32 and a transmission gear 33. Among them, the transmission worm 31 is fixedly installed at the output end of the fixed motor 25. The transmission worm wheel 32 is meshed with the transmission worm 31 and is rotatably installed at the bottom of the second ring body 152, that is, the side of the second ring body 152 facing the first ring body 151. The transmission gear 33 It is coaxially fixedly installed on the transmission worm wheel 32 and located at the top of the second ring body 152. The transmission gear 33 is engaged with the outer peripheral surface of the fixed drive ring 26, so that when the fixed motor 25 drives the transmission worm 31 to rotate, the transmission worm wheel 32 drives the fixed drive ring 26 to rotate together through the transmission worm wheel 32 and the transmission gear 33. The self-locking effect between the transmission worm wheel 32 and the transmission worm 31 is conducive to ensuring the stability of the position of the fixed drive ring 26 after the fixed rods 16 are finally driven to move, thereby facilitating the first fixing portion 161 of each fixed rod 16 to achieve stable clamping of the rotating rod.

[0052] The implementation principle of a mining geological exploration drilling and sampling device in an embodiment of the present application is: during the drilling and sampling process, the two clamping rods 8 are first driven by the clamping motor 10 to move in a direction close to each other to achieve clamping of the two sides of the drilling mounting seat 3, and then the first lifting mounting seat 7 and the drilling mounting seat 3 are fixed, and then the drill rig 2 drives the rotation of the drill rod 1 and the first linear module 6 drives the movement of its own slider to achieve downward drilling of the drill rod 1; after reaching the predetermined drilling depth or sampling volume, the clamping motor 10 drives the two clamping rods 8 to move in a direction away from each other to release the clamping and fixation of the two sides of the drilling mounting seat 3.

[0053] Subsequently, the fixed drive ring 26 is driven to rotate by the fixed motor 25, thereby driving each fixed rod 16 to move toward the axial direction of the fixed ring 15 so that each fixed rod 16 can achieve a tight fixation on the drill rod 1, and then cooperate with the second linear module 13 to drive the movement segment of its own slider to pull the drill rod 1 out of the drilling area, thereby finally achieving the removal of the drill rod 1 as a whole; each fixed rod 16 clamps the drill rod 1 and then removes the drill rod 1 through multiple vertical movements, which helps to reduce the shaking and deviation of the drill rod 1 during the removal process, thereby improving the drilling efficiency and ensuring the stability and accuracy of the drill rod 1 during the removal process. In addition, by clamping different parts of the drill rod 1 multiple times, it can better adapt to the changes in different strata and rock types, ensure the smooth progress of the drilling process, and reduce drilling accidents and losses caused by changes in geological conditions.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
