Description

Technical Field

[0001] This utility model relates to the field of mining sampling technology, specifically a sampling device for sandstone-type uranium mining. Background Technology

[0002] Sandstone-type uranium deposits are an important type of uranium resource, widely distributed globally, characterized by shallow burial, wide distribution, and complex ore body morphology. When setting up sampling equipment after locating the deposit, the complex terrain makes direct installation impossible; the ground must be leveled first. This complicates sampling operations, and the levelness of the equipment after leveling cannot be guaranteed. Deviation during sampling can lead to discrepancies in the actual drilling area, affecting the accuracy of the samples and causing inconvenience. Even after leveling, the complex terrain can cause rock fractures, leading to equipment vibration, affecting stability, and hindering normal operation. Utility Model Content

A vertical support rod is fixedly mounted on the top of the mounting base, and a mounting ring seat is fixedly mounted on the top of the vertical support rod. An adjustable tilt angle mounting platform is provided on the inner side of the mounting ring seat. A positioning device for fixing to the sandstone surface is provided at the bottom of the mounting base, and a counterweight ring is fixedly mounted on the bottom of the mounting platform.

[0007] Preferably, a positioning bracket is fixedly installed on the inner wall of the mounting ring seat, and the mounting platform is movably engaged with the inner side of the positioning bracket. The positioning bolt is threaded to the outer wall of the mounting ring seat, and the inner end of the positioning bolt passes through the positioning bracket and supports and fixes the outer wall of the mounting platform. A snap-fit ​​groove is provided on the top of the mounting platform, and a sliding bolt fixing seat is slidably engaged inside the snap-fit ​​groove. The sampling drilling equipment is installed and fixed by bolts and the sliding bolt fixing seat.

[0008] Preferably, the positioning device includes a mounting base, a positioning column, an adjusting shaft, a control threaded sleeve, a lower positioning sleeve, a lower positioning plate, an upper positioning sleeve, an upper positioning plate, an anti-slip nail head, and a mounting cavity. The mounting base is fixedly installed on the top of the mounting base. The positioning column is threadedly installed on the inner side of the mounting base, with its bottom end extending below the mounting base. The adjusting shaft is rotatably installed on the inner side of the positioning column via a bearing. The mounting cavity is formed on the surface of the positioning column. The lower and upper positioning sleeves are both engaged inside the mounting cavity. The control threaded sleeve is fixedly installed on the outer wall of the adjusting shaft. The control threaded sleeve is threadedly connected to the lower and upper positioning sleeves. The lower positioning plate is hinged to the outer wall of the lower positioning sleeve via a hinge. The upper positioning plate is hinged to the outer wall of the upper positioning sleeve via a hinge. The bottom end of the upper positioning plate and the inner side of the top end of the lower positioning plate are hinged together via a hinge. The anti-slip nail head is installed on the outer surface of the upper and lower positioning plates.

[0009] Preferably, the outer wall of the installation platform is spherical, and the inner wall of the positioning card seat is formed with a matching arc surface, so that the installation platform can deflect along the inner side of the positioning card seat.

[0010] Preferably, the threads on the upper and lower ends of the control threaded sleeve have opposite helical directions, the lower positioning sleeve is threadedly connected to the lower thread of the control threaded sleeve, and the upper positioning sleeve is threadedly connected to the upper thread of the control threaded sleeve.

[0013] Compared with the prior art, this utility model provides a sampling device for sandstone-type uranium mining, which has the following advantages:

[0014] 1. This sampling device for sandstone-type uranium mining involves drilling holes in the ground where sampling is required, inserting positioning pins into the holes, and then controlling the lower and upper positioning plates to extend outwards so that the anti-slip nail heads are engaged in the rock, thereby completing the fixing of the mounting base. By setting the fixing position within the rock strata, the stability of the fixing is prevented from being affected by ground vibrations, and it can also prevent displacement and shaking, thus improving the stability of subsequent sampling drilling.

[0015] 2. This sampling device for sandstone-type uranium mining, after the mounting base is fixed, has the center of gravity of the counterweight ring located below the center of gravity of the mounting platform. When the installation ground is uneven, the weight of the counterweight ring will cause the mounting platform to rotate along the inner side of the positioning bracket to a vertical state. Then, the mounting platform is fixed from the outside by the positioning bolts, so that the mounting plane at the top of the mounting platform is in a horizontal state. This allows the equipment installed above the mounting platform to perform vertical drilling and sampling during operation, ensuring the accuracy of the sampling points, preventing deviations, and improving the accuracy of sampling.

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

[0022] Please see Figure 1-4This utility model provides a sampling device for sandstone uranium mining, including a mounting base 1, a mounting platform 4, and a positioning device 6. A vertical support rod 2 is fixedly installed on the top of the mounting base 1, and a mounting ring seat 3 is fixedly installed on the top of the vertical support rod 2. The mounting platform 4, which can adjust the tilt angle, is provided on the inner side of the mounting ring seat 3. The positioning device 6 for fixing to the sandstone surface is provided on the bottom of the mounting base 1. A counterweight ring is fixedly installed on the bottom of the mounting platform 4. The center of gravity of the counterweight ring is located below the center of gravity of the mounting platform 4. When the ground is uneven, the weight of the counterweight ring will drive the mounting platform 4 to deflect to a vertical state along the inner side of the positioning seat 41. Then, the mounting platform 4 is fixed from the outside by the positioning bolt 42, so that the mounting plane at the top of the mounting platform 4 is in a horizontal state. This allows the equipment installed on the mounting platform 4 to perform vertical drilling and sampling during operation, ensuring the accuracy of the sampling point, preventing deviations, and improving the accuracy of sampling.

[0023] Furthermore, a positioning bracket 41 is fixedly installed on the inner wall of the mounting ring seat 3. The mounting platform 4 is movably engaged with the inner side of the positioning bracket 41. The positioning bolt 42 is threaded to the outer wall of the mounting ring seat 3. The inner end of the positioning bolt 42 passes through the positioning bracket 41 and supports and fixes the outer wall of the mounting platform 4. The top of the mounting platform 4 is provided with a snap-fit ​​groove 43. A sliding bolt fixing seat 44 is slidably engaged inside the snap-fit ​​groove 43. The sampling drilling equipment is installed and fixed by bolts and sliding bolt fixing seat 44. Through the cooperation of the mounting platform 4 and the positioning bracket 41, the installation angle of the mounting platform 4 can be adjusted. The adjusted mounting platform 4 is clamped and fixed from the outside by the positioning bolt 42.

[0024] Furthermore, the positioning device 6 includes a mounting base 61, a positioning pin 62, an adjusting shaft 63, a control threaded sleeve 64, a lower positioning sleeve 65, a lower positioning plate 66, an upper positioning sleeve 67, an upper positioning plate 68, an anti-slip screw head 69, and a mounting cavity 70. The mounting base 61 is fixedly mounted on the top of the mounting base 1. The positioning pin 62 is threaded onto the inner side of the mounting base 61, with its bottom end extending below the mounting base 1. The adjusting shaft 63 is rotatably mounted on the inner side of the positioning pin 62 via a bearing. The mounting cavity 70 is formed on the surface of the positioning pin 62. The lower positioning sleeve 65 and the upper positioning sleeve 67 are both engaged inside the mounting cavity 70. The threaded sleeve 64 is fixedly installed on the outer wall of the adjusting shaft 63. The control threaded sleeve 64 is threadedly connected to the lower positioning sleeve 65 and the upper positioning sleeve 67. The lower positioning plate 66 is hinged to the outer wall of the lower positioning sleeve 65 via a hinge. The upper positioning plate 68 is hinged to the outer wall of the upper positioning sleeve 67 via a hinge. The bottom end of the upper positioning plate 68 and the inner side of the top end of the lower positioning plate 66 are hinged. The anti-slip nail head 69 is installed on the outer side of the upper positioning plate 68 and the lower positioning plate 66. The positioning device 6 extends into the drilled rock hole to fix the mounting base 1. By extending into the rock layer for fixing, the fixing effect is improved.

[0025] Furthermore, the outer wall of the mounting platform 4 is spherical, and the inner wall of the positioning bracket 41 is formed with a matching arc surface. The mounting platform 4 can deflect along the inner side of the positioning bracket 41. The spherical contact surface design allows the mounting platform 4 to rotate to different directions, thereby increasing the adjustment angle range and improving the applicability.

[0026] Furthermore, the threads on the upper and lower ends of the control threaded sleeve 64 have opposite helical directions. The lower positioning sleeve 65 is threadedly connected to the lower thread of the control threaded sleeve 64, and the upper positioning sleeve 67 is threadedly connected to the upper thread of the control threaded sleeve 64. When the adjusting shaft 63 is rotated, the adjusting shaft 63 drives the control threaded sleeve 64 to rotate. The control threaded sleeve 64 drives the upper positioning sleeve 67 to move downward through the upper thread, and at the same time drives the lower positioning sleeve 65 to move upward through the lower thread.

[0027] Furthermore, the surface of the mounting platform 4 is provided with sampling holes 5 for supplying the drill bit to extend downwards, and the sampling drill rod extends straight down through the sampling holes 5 to perform drilling and sampling work.

[0028] Furthermore, there are several anti-slip nail heads 69, and the lengths of the anti-slip nail heads 69 are different. The length of the anti-slip nail head 69 gradually increases at the end away from the lower positioning plate 66 and the upper positioning plate 68 that are connected to each other. When the lower positioning plate 66 and the upper positioning plate 68 are deflected outward, the anti-slip nail head 69 in the middle position moves outward a greater distance than the anti-slip nail head 69 in the far middle position. This allows anti-slip nail heads 69 of different lengths to contact the inner wall of the rock hole simultaneously, improving the fixing effect. The position where the upper positioning plate 68 and the lower positioning plate 66 are connected protrudes outward. When the lower positioning sleeve 65 and the upper positioning sleeve 67 move closer to the middle, the ends of the lower positioning plate 66 and the upper positioning plate 68 will extend outward and will not move inward. The lower positioning plate 66 and the upper positioning plate 68 drive the anti-slip nail head 69 to extend outward and contact and engage with the inner wall of the rock hole, thereby completing the fixing work.

[0029] In use, a hole is drilled into the rock strata using drilling equipment. The positioning pin 62 is connected to the mounting base 61 by rotating it. The bottom end of the positioning pin 62 is inserted into the rock hole. Then, a wrench is used to rotate the adjusting shaft 63, which in turn rotates the threaded sleeve 64. This drives the lower positioning sleeve 65 upwards and the upper positioning sleeve 67 downwards, bringing them closer together. At this point, the connecting ends of the lower and upper positioning plates 66 and 68 extend outwards, causing the anti-slip nail heads 69 at their ends to extend outwards. The anti-slip nail heads 69 contact the inner wall of the rock hole, and pressure is used to fix the anti-slip nail heads 69 to the inner wall of the rock hole. This process is achieved by inserting the nail head into the rock hole and engaging with the inner wall. The snap-fit ​​fixing method can prevent the poor stability of the bottom surface rock from affecting the fixing stability. After all three positioning columns 62 are fixed, the mounting base 1 is kept stable. Then, the positioning bolt 42 is rotated to move outward, contacting the clamping of the mounting platform 4. The mounting platform 4 deflects under the gravity of the bottom counterweight, so that the center of gravity of the mounting platform 4 and the center of gravity of the counterweight are in the same vertical line. This keeps the surface of the mounting platform 4 for mounting the drilling and sampling equipment horizontal. Then, the positioning bolt 42 is rotated to move inward, clamping the outside of the mounting platform 4, thus fixing the mounting platform 4 and keeping the top of the mounting platform 4 horizontal. Then, the drilling and sampling equipment is installed by bolts and sliding bolt fixing seat 44, so that vertical drilling and sampling can be performed, improving the sampling accuracy.
