Description

Technical Field

[0002] During the process of mineral exploration, it is necessary to core and analyze underground mineral rocks to understand the mineral composition, chemical composition, and physical properties of the rocks or ores, so as to conduct qualitative analysis of the mineral types. According to the quality and distribution characteristics of the core samples, the reserves and grades of minerals can be preliminarily evaluated, providing an important basis for the development and utilization of mineral resources. During the design and construction of mine shafts, the core data can be used to guide the layout and driving direction of roadways, ensuring the safety and stability of the roadways.

[0034] Refer to Figure 1 , Figure 2 As shown, before starting the coring operation, the driving mechanism 4 is used to drive the second vertical seat 13 to move towards the coring surface, that is, the drilling mechanism 3 can drill a positioning hole on the coring surface; after the positioning hole is drilled, the driving mechanism 4 is used to drive the second vertical seat 13 to move away from the coring surface; the fixing component 51 is fixed in the positioning hole, and then the driving mechanism 4 is used to drive the first vertical seat 12 to drive the frame 2 to move towards the coring surface, and then the relative position between the positioning sleeve 52 and the fixing component 51 is fixed through the connecting component 53 (refer to Figure 3 ), and the coring mechanism 21 is moved towards the coring surface along the length direction of the frame 2, that is, the coring operation can be carried out. The fixing component 51 can provide a supporting force for the frame 2 during the coring operation, providing the stability of the frame 2 to avoid slipping due to the reaction force of the coring surface.

[0035] Refer to Figure 3 , Figure 4As shown, the fixing component 51 includes a fixing ring 511. Along the circumferential direction of the fixing ring 511, a plurality of tightening bolts 512 are distributed. The tightening bolts 512 are all threadedly connected to the fixing ring 511 in the radial direction of the fixing ring 511. By screwing the tightening bolts 512 and making the ends of the tightening bolts 512 abut against the hole wall of the positioning hole, the fixing ring 511 can be fixedly installed into the positioning hole. The connecting component 53 includes a connecting sleeve 531. A screw rod 532 is threadedly connected inside the connecting sleeve 531. A threaded hole for inserting the screw rod 532 is provided on the positioning sleeve 52. By rotating the screw rod 532 to make the screw rod 532 extend out of the connecting sleeve 531 and be threadedly connected to the threaded hole of the positioning sleeve 52, the relative position between the positioning sleeve 52 and the fixing ring 511 can be fixed, thereby fixing the relative position between the frame 2 and the positioning hole, so as to improve the stability of the frame 2 during the subsequent core-taking process.

[0036] Referring to Figure 5 As shown, the drilling mechanism 3 includes a drilling motor 31. On the side of the second vertical seat 13 facing the core-taking surface, a second motor seat 32 is welded. The drilling motor 31 is fixedly installed on the second motor seat 32. The output shaft of the drilling motor 31 is coaxially connected with a drilling disc 33. Start the drilling motor 31 to drive the drilling disc 33 to rotate, and then drive the second vertical seat 13 to move towards the core-taking surface and contact the core-taking surface through the driving mechanism 4. During the process of continuing to move forward for a certain distance, the drilling disc 33 can drill a positioning hole on the core-taking surface.

[0037] Referring to Figure 3 As shown, the core-taking mechanism 21 includes a core-taking seat 211, a core-taking motor 212, and a core-taking drill rod 213. The core-taking drill rod 213 is a hollow drill rod with a hollow interior. The core-taking seat 211 is slidably arranged in the frame 2 along the length direction of the frame 2. A moving component 22 for driving the core-taking seat 211 to move is arranged on the frame 2. The core-taking motor 212 is fixedly arranged on the core-taking seat 211. The core-taking drill rod 213 is fixedly connected to the output shaft of the core-taking motor 212. The moving component 22 includes a moving motor 221 and a lead screw 222. The lead screw 222 is rotatably connected in the frame 2. The moving motor 221 is fixedly arranged at one end of the frame 2 and the output shaft of the moving motor 221 is fixedly connected to the lead screw 222. A threaded hole is provided at one end of the core-taking seat 211 and is threadedly connected to the lead screw 222. Start the core-taking motor 212 to drive the lead screw 222 to rotate, which can drive the core-taking seat 211 to move along the length direction of the frame 2, thereby driving the core-taking to move towards the core-taking surface in the mine, and the core-taking rod can drill and take the core.

[0038] Referring to Figure 3 、 Figure 4As shown, the frame body 2 is rotatably installed between two first vertical seats 12. A turning member 14 for driving the frame body 2 to turn is provided on one of the first vertical seats 12. The turning member 14 includes a turning motor 141, a worm gear 142, and a worm 143. The frame body 2 is rotatably connected between two first vertical seats 12 through a rotating shaft 201. The worm gear 142 is coaxially connected to one end of the rotating shaft 201 located inside one of the first vertical seats 12. Two support blocks 144 are provided on the first vertical seat 12. The worm 143 is rotatably connected between the two support blocks 144 and meshes with the worm gear 142. The turning motor 141 is fixedly installed on one of the support blocks 144, and the output shaft of the turning motor 141 is fixedly connected to the worm 143. When the turning motor 141 is started to drive the worm 143 to rotate, the worm gear 142 rotates synchronously under the meshing of the worm 143, thereby driving the frame body 2 to rotate through the rotating shaft 201. And because there is a self-locking ability between the worm gear 142 and the worm 143, it can be kept in a specified position after driving the frame body 2 to rotate.

[0039] Refer to Figure 4 As shown, the connecting sleeve 531 and the fixing ring 511 are coaxially arranged and are rotatably connected inside the fixing ring 511 through a rotating column 533. The first vertical seat 12 includes a first base 121 and a first top seat 122. The first base 121 is hollow, and the first top seat 122 is slidably arranged inside the first base 121. An elevating electric cylinder 123 for driving the first top seat 122 to move along the length direction of the first base 121 is provided on the first base 121. When the core-taking direction needs to be inclined upward or downward, the frame body 2 is driven by the turning member 14 to rotate to a specified state, and then the first top seat 122 is driven by the elevating electric cylinder 123 to move a corresponding height into or out of the first base 121. When the fixing ring 511 is installed in the positioning hole, the rotating column 533 is in a horizontal state, and then the connecting sleeve 531 is rotated upward or downward, and the screw 532 is screwed and threadedly connected into the positioning sleeve 52, so as to realize the fixing effect between the frame body 2 in an inclined state in the up and down direction and the positioning hole.

[0040] Refer to Figure 1 、 Figure 3As shown, the support disk 11 is rotatably arranged on the base 1. A rotating member 16 for driving the support disk 11 to rotate is arranged on the base 1. The rotating member 16 includes a rotating motor 161, a driving gear 162 and a driven toothed ring 163. A first motor base 164 is fixedly arranged on the base 1. The rotating motor 161 is fixedly arranged on the first motor base 164. The driving gear 162 is coaxially connected to the output shaft of the rotating motor 161. The driven toothed ring 163 is coaxially connected to the support disk 11 and meshes with the driving gear 162. Starting the rotating motor 161 drives the driving gear 162 to rotate. The driven gear drives the support disk 11 to rotate under the meshing action of the driving gear 162, so as to drive the frame 2 and the core-taking mechanism 21 to deflect in the left-right direction. When installing the fixing ring 511 into the positioning hole, make the rotating column 533 in the vertical state, and then rotate the connecting sleeve 531 to the left or right. Screw the screw 532 and thread the screw 532 into the positioning sleeve 52, that is, to realize the fixing effect between the frame 2 in the inclined state in the left-right direction and the positioning hole.

[0041] Referring to Figure 5 、 Figure 6 As shown, the driving mechanism 4 includes a driving electric cylinder 41 and a driving block 42. The cylinder barrel of the driving electric cylinder 41 is fixedly installed on the support disk 11. The driving block 42 includes a first support block 421 and a second support block 422. The first support block 421 is rotatably connected to the piston rod of the driving electric cylinder 41. Referring to Figure 7 As shown, a first telescopic groove 4211 is opened at one end of the first support block 421. The second support block 422 is slidably arranged in the first telescopic groove 4211 and one end of the second support block 422 extends out of the first telescopic groove 4211. Driving grooves 15 for inserting the second support block 422 are opened on both sides of the second vertical seat 13 and on the side of the two first vertical seats 12 close to each other. When drilling the positioning hole on the core-taking surface in the mine, rotate the first support block 421 and make the second support block 422 face the second vertical seat 13, and then insert the second support block 422 into the driving groove 15 of the second vertical seat 13. Start the driving electric cylinder 41 and make the piston rod of the driving electric cylinder 41 move out of the cylinder barrel, that is, it can drive the second vertical seat 13 to move towards the core-taking surface, so that the drilling mechanism 3 drills out the positioning hole on the core-taking surface; when taking the core, drive the second vertical seat 13 to move away from the core-taking surface through the driving electric cylinder 41, and take out the second support block 422 from the driving groove 15 of the second vertical seat 13. Rotate the first support block 421 by 180° and insert the second support block 422 into the driving groove 15 of the first vertical seat 12. Start the driving electric cylinder 41 and make the piston rod of the driving electric cylinder 41 move out of the cylinder barrel, driving the first vertical seat 12 to move towards the core-taking surface, so that the core-taking mechanism 21 performs the core-taking operation on the core-taking surface.

[0042] Referring to Figure 5 、 Figure 6As shown, the second vertical seat 13 includes a second base 131 and a second top seat 132. The second base 131 is hollow, and the second top seat 132 is slidably arranged within the second base 131. A positioning groove 1321 is formed on one side of the second top seat 132 located within the second base 131. A second telescopic groove 4221 is formed at one end of the second support block 422 facing the positioning groove 1321. A positioning block 43 is arranged within the second telescopic groove 4221. When the second top seat 132 moves outward relative to the second base 131, the positioning block 43 can be inserted into the positioning groove 1321. When drilling operations are carried out, it is necessary to move the second top seat 132 outward relative to the second base 131 to increase the overall height of the second vertical seat 13. When the second top seat 132 moves upward to a specified position, the positioning block 43 is inserted into the positioning groove 1321 to fix the position of the second top seat 132. After the drilling operations are completed, it is necessary to move the second top seat 132 inward relative to the second base 131 to reduce the overall height of the second vertical seat 13, so that the overall height of the drilling mechanism 3 is lower than the height of the frame 2 for the frame 2 to pass through. At this time, the second support block 422 is moved into the first support block 421 and separated from the driving groove 15. At the same time, the positioning block 43 moves out of the positioning groove 1321 to release the fixation of the position of the second top seat 132. Under the action of the self-weights of the drilling mechanism 3 and the second top seat 132, the second top seat 132 moves into the second base 131, reducing the overall height of the second vertical seat 13 so that the frame 2 can pass above the drilling mechanism 3.

[0043] Refer to Figure 6 , Figure 7 As shown, a first return spring 423 for driving the second support block 422 to move outward relative to the bottom wall of the first telescopic groove 4211 is connected between the second support block 422 and the bottom wall of the first telescopic groove 4211. A traction member 44 is arranged within the second support block 422. One end of the traction member 44 is located within the second telescopic groove 4221, and the other end passes through the first telescopic groove 4211 and extends outside the first support block 421. A second return spring 431 is connected between the positioning block 43 and one end of the traction member 44 located within the second telescopic groove 4221. When it is necessary to move the second support block 422 out of the driving groove 15, by pulling the traction member 44, the second support block 422 can be driven to move into the first support block 421, thereby disengaging from the driving groove 15, facilitating the process of releasing the fixation of the position between the driving block 42 and the first vertical seat 12 or the second vertical seat 13.

[0044] Refer to Figure 7As shown, the traction member 44 includes a traction rod 441. One end of the second support block 422 facing the first support block 421 is provided with a threaded hole. The traction rod 441 is provided with an external thread and is threadedly connected in the threaded hole. The first support block 421 is provided with a through hole 4212 for the traction rod 441 to pass through. One end of the traction rod 441 extends outside the through hole 4212 and is fixedly provided with a pulling handle 442. The other end of the traction rod 441 extends into the second telescopic groove 4221 and is rotatably provided with a support piece 443. The second return spring 431 is connected between the support piece 443 and the positioning block 43. In the initial state, both the first return spring 423 and the second return spring 431 are in the original length state. One end of the second support block 422 extends outside the first support block 421, and one end of the positioning block 43 extends outside the second support block 422. By rotating the pulling handle 442 and moving the support piece 443 towards the bottom wall of the second telescopic groove 4221, the whole positioning block 43 can be driven to move into the second telescopic groove 4221 and disengage from the positioning groove 1321. Then, by pulling the traction rod 441 through the pulling handle 442, since the traction rod 441 is connected to the second support block 422 in a threaded connection manner, when the traction rod 441 moves, it can drive the second support block 422 to move into the first telescopic groove 4211, so that the second support block 422 is separated from the driving groove 15.

[0045] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
