Description

Technical Field

[0001] The present invention relates to the technical field of mine geological exploration, and particularly to a mine geological exploration device. Background Art

[0002] When conducting geological exploration on mines such as gold mines, the precise installation and stable operation of underground detection equipment (such as rock layer imagers, ultrasonic sensors, etc.) rely on the quality of the inner wall of the pre-drilled exploration holes. Traditional exploration holes mostly adopt a circular cross-section design, and the inner wall grinding technology is relatively mature, usually achieved through grinding tools with a fixed diameter or rigid guiding devices.

[0003] However, there are the following technical bottlenecks in actual projects: 1. Contradiction between mine requirements and processing: Under complex geological conditions (such as fractured rock formations or alternating hard and soft strata), irregular deformations are likely to occur during the drilling process, resulting in the hole channels presenting abnormal cross-sections such as ellipses and polygons. Existing grinding equipment, limited by fixed-size grinding heads or rigid structures, cannot conform to the contour of the mine wall, causing problems such as uneven grinding and local residual protrusions, seriously affecting the contact stability between the sensor and the hole wall, and leading to distorted exploration data. 2. Insufficient dynamic adaptability: The exploration holes in mines often undergo secondary deformations due to rock mass stress release or groundwater erosion, and periodic re-inspections and re-grinding are required. Traditional technologies rely on manual intervention to adjust grinding parameters, with low efficiency and safety risks in underground operations, and it is difficult to meet the adaptive operation and maintenance requirements of intelligent exploration equipment. 3. Compatibility and cost constraints: Although special treatment solutions for mine holes (such as customized mold guiding, segmented grinding processes) can solve some problems, the equipment has poor compatibility and complex processes, significantly increasing the cost of mine exploration and restricting the promotion of technologies.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Example 1, please refer to Figures 1-8 , a mine geological survey device, including a housing 200, on which a grinding mechanism 300 is provided, and the grinding mechanism 300 is used to grind the mine tunnel 100.

[0043] The grinding mechanism 300 includes an installation pipe 310 slidably arranged on the housing 200. A number of grinding wheel assemblies 320 are circumferentially and equidistantly arranged on the installation pipe 310. The grinding wheel assembly 320 includes a rotating cylinder 321 rotatably arranged on the installation pipe 310. A first sliding groove 322 is formed in the rotating cylinder 321. A sliding rod 323 is slidably arranged in the first sliding groove 322. One end of the sliding rod 323 is elastically connected to the inner wall of the first sliding groove 322 through a first spring 325, and the other end of the sliding rod 323 is connected to a grinding wheel 324.

[0044] The grinding mechanism 300 further includes a first rotating assembly 330, which is used to drive the installation pipe 310 and a number of grinding wheels 324 to rotate along the inner wall of the mine tunnel 100 for grinding.

[0045] The grinding wheel assembly 320 further includes a universal joint 326 and a second spring 327. The two ends of the universal joint 326 are respectively connected to the sliding rod 323 and the grinding wheel 324, and the two ends of the universal joint 326 are elastically connected through the second spring 327.

[0046] The first rotating assembly 330 includes a limiting block 331 arranged on the installation pipe 310. A connecting cylinder 333 is arranged in the housing 200. A second sliding groove 332 is formed in the connecting cylinder 333, and the limiting block 331 is slidably connected in the second sliding groove 332.

[0047] In this embodiment: The mine tunnel 100 with the feature of a special-shaped hole in the legend is oval, and it can actually be other shapes. After the housing 200 is erected, when the connecting cylinder 333 rotates in place in the housing 200, and then the installation pipe 310 is driven to move up and down reciprocally. Since the limiting block 331 on the installation pipe 310 is polygonal, and the limiting block 331 slides along the second sliding groove 332 which is also polygonal, the installation pipe 310 will rotate while moving up and down, thereby driving a number of grinding wheels 324 to perform circular motion and up and down motion along the inner wall of the mine tunnel 100 for grinding.

[0048] During the grinding process, a number of grinding wheels 324 are attached to the inner wall of the mine tunnel 100 under the elastic force of the first spring 325. According to the change of the inner diameter, the sliding rod 323 and the grinding wheel 324 can slide relative to each other in the rotating cylinder 321 to automatically adjust the distance.

[0049] The grinding wheel 324 is connected to the sliding rod 323 through a universal shaft 326 and a second spring 327. The elastic force of the second spring 327 keeps it in a vertical state, and when it contacts the port of the mine tunnel 100, it can also grind the port. When the installation pipe 310 further extends into the mine tunnel 100, several grinding wheels 324 deflect to a horizontal state and closely adhere to the inner wall of the mine tunnel 100.

[0050] Embodiment 2 is an improved description based on Embodiment 1. Specifically, please refer to Figures 1-9 , the grinding mechanism 300 further includes a second rotation assembly 340, and the second rotation assembly 340 is used to drive several grinding wheels 324 to rotate self while making a circular motion around the installation pipe 310.

[0051] The second rotation assembly 340 includes a fixed pipe 343 arranged in the housing 200. A third chute 344 is opened on the fixed pipe 343. A sliding pipe 345 is slidably arranged in the third chute 344. A first bevel gear 341 is arranged on the sliding pipe 345. Second bevel gears 342 are arranged on several rotating cylinders 321, and several second bevel gears 342 are all meshed with the first bevel gear 341.

[0052] The grinding mechanism 300 further includes a driving assembly 350, and the driving assembly 350 is used to drive the installation pipe 310 to reciprocally slide along the inner wall of the mine tunnel 100 and drive the first rotation assembly 330 and the second rotation assembly 340 to operate.

[0053] The driving assembly 350 includes a motor 351 arranged in the housing 200. A third bevel gear 352 is arranged on the output shaft of the motor 351. A fourth bevel gear 353 meshed with the third bevel gear 352 is arranged on the connecting cylinder 333.

[0054] A rotating rod 354 is rotatably arranged on the housing 200. A fifth bevel gear 355 meshed with the fourth bevel gear 353 is arranged at one end of the rotating rod 354, and a turntable 356 is arranged at the other end of the rotating rod 354.

[0055] The driving assembly 350 further includes a connecting rod 357. One end of the connecting rod 357 is rotatably connected to the edge of the turntable 356 through a rotating shaft. The other end of the connecting rod 357 is rotatably connected with a push plate 358 through a rotating shaft. The connecting cylinder 333 is rotatably connected to the push plate 358.

[0056] In this embodiment: The sliding pipe 345 moves along with the first water pipe 410 through the connection of the rotating block 450 and the rotating groove 460, and the first water pipe 410 moves along with the installation pipe 310. By sliding the sliding pipe 345 within the polygonal third sliding groove 344, the angle of the first bevel gear 341 can be kept unchanged. Furthermore, while several rotating cylinders 321 and grinding wheels 324 rotate along with the installation pipe 310, through the meshing of the second bevel gear 342 and the first bevel gear 341, the rotating cylinders 321 and the grinding wheels 324 rotate self - sufficiently.

[0057] When the motor 351 operates, it can drive the fourth bevel gear 353 and the fifth bevel gear 355 to rotate. The rotation of the fourth bevel gear 353 drives the grinding wheel 324 to rotate self - sufficiently while making a circular motion. When the fifth bevel gear 355 rotates, it drives the rotating rod 354 and the turntable 356 to rotate, and then drives the connecting cylinder 333 and the installation pipe 310 to make a reciprocating up - and - down motion through the transmission of the connecting rod 357.

[0058] Embodiment 3 is an improved description based on Embodiment 2. Specifically, please refer to Figures 1-9 , a cooling mechanism 400 is further provided on the housing 200, and the cooling mechanism 400 is used to spray cooling water onto the inner wall of the mine tunnel 100.

[0059] The cooling mechanism 400 includes a first water pipe 410. Several rotating cylinders 321 are all connected to the first water pipe 410. A first communication groove 420 is opened on the first water pipe 410. Several second communication grooves 430 are opened on several rotating cylinders 321, and several second communication grooves 430 are all communicated with the first communication groove 420. Several water spraying holes 440 communicated with the second communication grooves 430 are further opened on the rotating cylinders 321.

[0060] A rotating block 450 is provided on the first water pipe 410. A rotating groove 460 is opened on the sliding pipe 345, and the rotating block 450 is rotatably connected within the rotating groove 460.

[0061] An injection mechanism 500 is further provided on the housing 200, and the injection mechanism 500 is used to inject water into the first water pipe 410.

[0062] The injection mechanism 500 includes a second water pipe 510 provided on the housing 200. A fourth sliding groove 520 is opened on the second water pipe 510, and the first water pipe 410 is slidably connected within the fourth sliding groove 520.

[0063] Several adjusting components 530 are provided on several rotating cylinders 321, and the adjusting components 530 are used to adjust the size of the water flow sprayed out from several water spraying holes 440.

[0064] The adjusting assembly 530 includes a piston rod 531 disposed on the sliding rod 323. A first piston 532 is provided on the piston rod 531. A fourth communication groove 533 is formed in the rotary cylinder 321. The second communication groove 430 communicates with a plurality of water spraying holes 440 through the fourth communication groove 533, and the fourth communication groove 533 is configured as a cone with its tip facing the direction of the second communication groove 430.

[0065] In this embodiment: Water is injected into the second water pipe 510 through the water pump assembly 540. The cooling water enters the water spraying holes 440 through the first communication groove 420, the second communication groove 430, and the fourth communication groove 533, and then the cooling water is sprayed from the plurality of water spraying holes 440 onto the inner wall of the mine tunnel 100 to cool the grinding process. At the same time, since the first water pipe 410 is fixed to the plurality of rotary cylinders 321, as the installation pipe 310 moves, the first water pipe 410 maintains waterway communication during the movement through the annular fourth sliding groove 520.

[0066] According to the change in the inner diameter of the mine tunnel 100, the distance between the water spraying holes 440 and the inner wall of the mine tunnel 100 changes. At this time, the fixed water pressure will cause differences in the cooling effect, thereby affecting the grinding effect. To unify the cooling effect, when the sliding rod 323 automatically expands and contracts with the change in the inner diameter of the mine tunnel 100, it drives the piston rod 531 and the first piston 532 to move radially relative to the first water pipe 410. Since the fourth communication groove 533 is conical, when the inner diameter of the mine tunnel 100 decreases, the passage area formed by the first piston 532 and the fourth communication groove 533 decreases, thereby reducing the size of the sprayed water flow.

[0067] Embodiment 4 is an improved description based on Embodiment 3. Specifically, please refer to Figures 2-10 The water injection mechanism 500 further includes a water pump assembly 540. The water pump assembly 540 includes a third water pipe 541 disposed on the housing 200. The third water pipe 541 is connected to the second water pipe 510, and a fourth water pipe 542 is provided on the third water pipe 541.

[0068] A fixed plug 543 and a second piston 544 are disposed in the third water pipe 541. Check valves 545 are provided on both the fixed plug 543 and the second piston 544. The two check valves 545 are used to restrict the unidirectional flow of the cooling water from the upper end of the third water pipe 541 to the lower end of the third water pipe 541.

[0069] The second piston 544 is connected to the push plate 358 through a connecting member 546. A sealing block 547 is provided on the connecting member 546. A sealing groove 548 is formed in the third water pipe 541. The sealing block 547 is slidably connected to the sealing groove 548.

[0070] In this embodiment: The fourth water pipe 542 can be connected to an external water source such as tap water, and the water pump assembly 540 is driven to operate by the push plate 358. The second piston 544 makes a reciprocating up-and-down sliding driven by the push plate 358 and the connecting member 546. Both one-way valves 545 restrict the water flow to flow unidirectionally from top to bottom. When the second piston 544 and the one-way valve 545 on the upper side move upward, the one-way valve 545 on the lower side closes, while the one-way valve 545 on the upper side opens, creating a negative pressure environment between the fixed plug 543 and the second piston 544. Under the pressure difference between the negative pressure environment and the water source, the cooling water is pumped into the space between the fixed plug 543 and the second piston 544.

[0071] When the second piston 544 and the one-way valve 545 on the upper side move downward, the one-way valve 545 on the lower side opens, and the one-way valve 545 on the upper side closes, allowing the water flow to enter the first water pipe 410 from the lower end of the fixed plug 543.

[0072] In addition, when the sealing block 547 makes a reciprocating up-and-down movement along with the connecting member 546, the upper and lower ends of the sealing block 547 are respectively connected to the upper and lower inner walls of the sealing groove 548, so that when the connecting member 546 moves up and down, the water flow will not leak from the sealing groove 548.

[0073] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0074] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
