Description

Technical Field

[0001] This invention belongs to the field of rock mechanics test specimen preparation technology, specifically relating to a device for the precise preparation of energy-absorbing anchor solid structures and its preparation method. Background Technology

[0002] Due to its superior safety and reliability, ease of operation, and significant economic advantages, rock bolt support has been widely used in coal mine roadways in my country. The basic principle of anchoring technology lies in using the bonding force provided by the anchoring agent to bond the anchor bolt to the reinforced rock and soil mass into a load-bearing assembly, thereby improving the stability of the reinforced body.

[0003] Many scholars have studied the distribution patterns of axial force, shear stress, and anchoring force of anchor rods (cables) under different constraint conditions by preparing anchor body samples in the laboratory and taking the interaction relationship between anchor rods, anchoring agents, and surrounding rock as the starting point.

[0004] The current mainstream process for preparing anchor solid specimens still follows the traditional technical route. The standard operating procedure is as follows: First, the specimen is poured into the mold. Then, the anchor hole structure is reserved in the center of the specimen. After the standard curing cycle, the specimen is manually demolded and prepared as an anchor solid specimen.

[0005] However, the existing operating method requires manual positioning of the anchor rod by tightening multiple bolts after inserting it into the reserved anchor hole. This makes it difficult to achieve precise concentric positioning of the anchor rod and the anchor hole, resulting in insufficient positioning accuracy and potentially affecting the accuracy of experimental data. Summary of the Invention

[0012] Preferably, the bottom surface of the arc-shaped track is provided with a connector, and the two ends of the connector are fixedly connected to the arc-shaped track and the second arc-shaped plate respectively. The arc surface of the second arc-shaped plate has two sliding grooves, and the positioning plate is slidably connected inside the sliding grooves.

The connecting rod is fixedly connected to the surface of the rectangular block, and three second springs are fixedly connected to the surface of the rectangular block. All three second springs are fixedly connected to the inner wall of the square groove. The size of the rectangular block is smaller than the size of the square groove.

[0015] Preferably, the surface of the connector is provided with a groove, the connecting rod passes through the connector through the groove, and the end of the connecting rod away from the rectangular block is fixedly connected to a connecting block.

[0016] Preferably, the surface of the frame is also provided with a lifting platform, the output end of the lifting platform is fixedly connected to an installation plate, the end face of the installation plate is provided with a first clamping plate, a second clamping plate is provided on one side of the first clamping plate, the anchor bolt mold is located between the first clamping plate and the second clamping plate, the surface of the first clamping plate is threaded with two screws, and the arc surface of the anchor bolt mold is threaded with a nut.

[0017] A method for precise fabrication of energy-absorbing anchor solid structures.

[0018] S1. Place a layer of polyethylene foam hollow thin tube with the same inner diameter as the outer diameter of the anchor bolt mold on the surface of the anchor bolt mold and fix it firmly with structural adhesive, etc., and evenly coat the surface of the polyethylene foam hollow thin tube with a layer of water-based release agent, so that the whole tube can be used as a mold and inserted into the sleeve for concrete pouring.

[0019] S2. After the standard curing period, ensure that the concrete strength meets the requirements. Before demolding, check whether the surface of the demolding template is flat and smooth, and conduct a trial demolding to check whether the application of the release agent and the condition of the concrete surface meet the requirements.

[0020] S3. When demolding, remove the anchor bolt mold and the polyethylene foam hollow thin tube as a whole. Tools (such as hydraulic tools) can be used to assist in demolding. After demolding, if some polyethylene foam is stuck to the concrete, physical methods (such as using a knife) can be used to pry the foam to separate it from the concrete.

[0021] S4. After demolding, check the quality of the concrete surface. If there are any defects, repair them in time. At the same time, clean and smooth the surface of the mold. If there is any damage or rough edges, repair them in time to prepare for the next use.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention involves setting a circular tube on the anchor bolt mold. During the downward movement of the anchor bolt mold, the circular tube engages with two lower baffles to achieve gear and tooth block transmission, thereby merging the two first arc-shaped plates together to surround the anchor bolt mold. As the anchor bolt mold continues to move downward, the circular tube engages with the connecting rod through its own spiral groove, causing the first arc-shaped plates to rotate and press against multiple positioning plates. By having multiple positioning plates move towards the center simultaneously, the anchor bolt mold is pressed, achieving the effect of center positioning of the anchor bolt mold and aligning the center of the anchor bolt mold with that of the sleeve.

[0024] During the downward movement of the anchor bolt mold, the round tube first cooperates with the baffle to merge the first arc plate together and surround the anchor bolt mold. Then, the round tube cooperates with the connecting rod to make the first arc plate rotate, achieving the effect of automatic center positioning, making the operation more convenient.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Reference Figures 1-12 As shown, the present invention provides a device for precise preparation of energy-absorbing anchor solid structures, including a frame 1, a first motor 102 fixedly installed on the surface of the frame 1, a transmission box 103 installed at the output end of the first motor 102, the transmission box 103 installed on the surface of the frame 1, a three-jaw chuck 104 installed on the end face of the transmission box 103, a sleeve 105 installed on the end face of the three-jaw chuck 104, and an anchor bolt mold 101 provided above the sleeve 105;

[0043] In this embodiment, the first motor 102 and the transmission box 103 are existing technologies. The transmission box 103 is equipped with a transmission component that is connected to the output end of the first motor 102 and the bottom of the three-jaw chuck 104, so that the first motor 102 can drive the three-jaw chuck 104 to rotate after starting. The three-jaw chuck 104 is existing technology and plays the role of clamping the sleeve 105. The above are technologies well known to those skilled in the art, and will not be described in detail here.

[0044] The clamping mechanism 2 includes two fixed rails 201 that are fixedly connected to the inner walls of the frame 1 on both sides. The inner walls of the two fixed rails 201 are slidably connected to the slide plates 202. The ends of the two slide plates 202 that are close to each other are fixedly connected to the arc-shaped rails 203. The inner walls of the two arc-shaped rails 203 are slidably connected to the first arc-shaped plate 204. The sleeve 105 is provided with two baffles 211 above it. The ends of the two baffles 211 that are far from each other are fixedly connected to the magnet plates 210. The magnet plates 210 are provided with gears 212 above them. The bottom surface of the slide plates 202 is fixedly connected to multiple tooth blocks 213. The gears 212 are located below the slide plates 202. The arc surface of the anchor bolt mold 101 is fixedly connected to the round tube 216.

[0045] In this embodiment, the internal groove of the fixed track 201 is shaped like an inverted convex character to facilitate the movement of the toothed block 213. The distance between the two baffles 211 is greater than the diameter of the anchor bolt mold 101 and less than the diameter of the round tube 216, so that when the anchor bolt mold 101 moves down, it can pass through first and then be squeezed by the round tube 216 onto the baffle 211, thereby facilitating the movement of the anchor bolt mold 101 to the bottom of the sleeve 105.

[0046] In an optional embodiment: a locking block 205 is fixedly connected to one end of the first arc plate 204, and a slot 206 adapted to the locking block 205 is opened at the other end of the first arc plate 204. A fixing plate 207 is fixedly connected to the surface of the fixing track 201. A rotating rod 208 is rotatably connected to the surface of the fixing plate 207. A connecting plate 209 is fixedly connected to the arc surface of the rotating rod 208. A magnet plate 210 is fixedly connected to the bottom surface of the connecting plate 209. A gear 212 is fixedly connected to the arc surface of the rotating rod 208.

[0047] It should be noted that the two first arc-shaped plates 204 will eventually engage with each other using the locking blocks 205 and the slots 206 on each other to form a complete circle. The two first arc-shaped plates 204 after being merged can rotate in the two arc-shaped tracks 203. After the magnet plate 210 is detached from the connector 301, it will swing under the action of gravity. At this time, the rotating rod 208 will drive the gear 212 to rotate. The gear 212 will transmit power to multiple tooth blocks 213, so that the two slide plates 202 will slide out from the fixed track 201. The two first arc-shaped plates 204 will eventually engage with each other using the locking blocks 205 and the slots 206 on each other. It should be noted that when the baffle 211 swings to the lowest point under its own gravity, the gear 212 is still engaged with the tooth blocks 213.

[0048] In an optional embodiment: a positioning mechanism 3, comprising two second arc-shaped plates 302 located between two first arc-shaped plates 204, each of the inner arc surfaces of the two first arc-shaped plates 204 having two limiting grooves 308, and each of the arc surfaces of the two second arc-shaped plates 302 being slidably connected to two positioning plates 304, the surface of the first arc-shaped plate 204 being provided with a connecting rod 312, and the arc surface of the round tube 216 being provided with multiple spiral grooves 315 that cooperate with the connecting rod 312, the multiple spiral grooves 315 serving to ensure that the connecting rod 312 can be inserted into one of the spiral grooves 315 when moving.

[0049] The bottom surface of the arc track 203 is provided with a connector 301. The two ends of the connector 301 are fixedly connected to the arc track 203 and the second arc plate 302 respectively. The arc surface of the second arc plate 302 is provided with two sliding grooves 303. The positioning plate 304 is slidably connected inside the sliding groove 303. The bottom surface of the positioning plate 304 is fixedly connected with a first block 305. The surface of the first block 305 is fixedly connected with a first spring 306. The other end of the first spring 306 is fixedly connected with a second block 307. The second block 307 is fixedly connected to the inner bottom wall of the sliding groove 303.

[0050] It should be noted that the connector 301 is made of iron material. In the initial state, it is attracted to the magnet plate 210. The cross-sectional shape of the slide groove 303 is an inverted convex shape. The first spring 306 facilitates the rebound of the positioning plate 304.

[0051] In an optional embodiment: a square groove 309 is provided on the inner arc surface of the first arc plate 204, a rectangular block 310 is slidably provided inside the square groove 309, a connecting rod 312 is fixedly connected to the surface of the rectangular block 310, three second springs 311 are fixedly connected to the surface of the rectangular block 310, and all three second springs 311 are fixedly connected to the inner wall of the square groove 309. The size of the rectangular block 310 is smaller than the size of the square groove 309. A groove 314 is provided on the surface of the connector 301, and the connecting rod 312 passes through the connector 301 through the groove 314. A connecting block 313 is fixedly connected to the end of the connecting rod 312 away from the rectangular block 310. The connecting block 313 is hemispherical in shape so that it can slide when squeezed.

[0052] It should be noted that the height of the rectangular block 310 is the same as the height of the square groove 309, which restricts the rectangular block 310 to move only laterally inside the square groove 309. When the round tube 216 is pressed to the center position by the positioning plate 304, the position of the round tube 216 changes, and the position of the connecting rod 312 will change. The connecting rod 312 will drive the rectangular block 310 to move inside the square groove 309. The second spring 311 will be compressed and deformed. The second spring 311 plays the role of stabilizing the rectangular block 310 inside the square groove 309, so that the rectangular block 310 will not fall out of the square groove 309. Since the spiral groove 315 has a certain depth, the connecting rod 312 is not easy to slip out of the spiral groove 315.

[0053] When the two first arc-shaped plates 204 are joined together, the connecting rod 312 will contact the arc surface of the circular tube 216. One of the second springs 311 is in a compressed state. At this time, two situations will occur. First, as the circular tube 216 continues to move downward, the connecting rod 312 will be aligned with one of the spiral grooves 315. The compressed second spring 311 will rebound, causing the connecting rod 312 to drive the connecting block 313 to slide into one of the spiral grooves 315. As the circular tube 216 moves downward, the connecting rod 312 slides along the inner wall of the spiral groove 315, causing the two to merge. After the first arc plate 204 rotates, in the second case, the connecting rod 312 is between two adjacent spiral grooves 315. Since the spiral grooves 315 are spiral-shaped, as the round tube 216 continues to move downward, when the connecting block 313 is in the position of the spiral groove 315, the compressed second spring 311 will rebound. The connecting rod 312 will drive the connecting block 313 to slide into one of the spiral grooves 315. As the round tube 216 moves downward, the connecting rod 312 slides along the inner wall of the spiral groove 315, causing the two merged first arc plates 204 to rotate.

[0054] In an optional embodiment: the surface of the frame 1 is also provided with a lift 4, the output end of the lift 4 is fixedly connected to a mounting plate 401, a first clamping plate 402 is installed on the end face of the mounting plate 401, a second clamping plate 403 is provided on one side of the first clamping plate 402, the anchor bolt mold 101 is located between the first clamping plate 402 and the second clamping plate 403, two screws 404 are threadedly connected to the surface of the first clamping plate 402, and a nut 405 is threadedly connected to the arc surface of the anchor bolt mold 101;

[0055] The second clamping plate 403 has screw holes at the positions corresponding to the two screws 404. By placing the anchor bolt mold 101 between the first clamping plate 402 and the second clamping plate 403, and by turning the two screws 404, the two screws 404 are inserted into the corresponding screw holes on the second clamping plate 403 to clamp the anchor bolt mold 101. Then, the nut 405 is installed on the anchor bolt mold 101 to further improve the stability of the anchor bolt mold 101.

[0056] In this embodiment, the elevator 4 is existing technology, consisting of a motor, telescopic rod and other transmission components. It is a technology well known to those skilled in the art, and will not be described in detail here. After the first clamping plate 402 and the second clamping plate 403 complete the clamping of the anchor bolt mold 101, the center position of the clamped part of the anchor bolt mold 101 is basically concentric with the lower sleeve 105.

[0057] In summary, during the downward movement of the anchor bolt mold 101, the round tube 216 first cooperates with the baffle 211 to merge the first arc plate 204 together and surround the anchor bolt mold 101. Then, the round tube 216 cooperates with the connecting rod 312 to make the first arc plate 204 rotate, achieving the effect of automatic center positioning, making the operation more convenient.

[0058] The working principle of the present invention is as follows: When in use, because the anchor bolt mold 101 is too long, when the anchor bolt mold 101 moves downward, the lower end of the anchor bolt mold 101 is prone to slight swaying, causing the bottom end of the anchor bolt mold 101 and the center of the sleeve 105 to be out of concentricity.

[0059] First, a layer of polyethylene foam hollow thin tube with the same inner diameter as the outer diameter of the anchor bolt mold 101 is fitted onto the surface of the anchor bolt mold 101 and fixed firmly with structural adhesive, etc. Then, the round tube 216 is fixed to a suitable position on the outer surface of the polyethylene foam hollow thin tube with glue, and a layer of water-based release agent is evenly applied to the surface of the polyethylene foam hollow thin tube and the surface of the round tube 216, so that the whole is used as a mold and inserted into the sleeve 105 for concrete pouring;

[0060] Next, the anchor bolt mold 101 is placed between the first clamping plate 402 and the second clamping plate 403. Two screws 404 are tightened into corresponding screw holes on the second clamping plate 403 to clamp the anchor bolt mold 101. Then, a nut 405 is installed on the anchor bolt mold 101 to further enhance its stability. It is important to ensure that the bottom end of the anchor bolt mold 101 is positioned between the two baffles 211. Then, the elevator 4 is started via an external power controller, causing the anchor bolt mold 101 to descend. The bottom end of the anchor bolt mold 101 passes between the two baffles 211. As the anchor bolt mold 101 descends, the round tube 216 is pressed against the two baffles 211, causing the baffles 211 to be compressed. As the magnetic plate 210 swings downwards, it detaches from the attraction of the connector 301. Under the weight of the baffle 211 itself, the baffle 211 and the magnetic plate 210 continue to swing downwards, disengaging from the circular tube 216. During the swing of the magnetic plate 210, the rotating rod 208 drives the gear 212 to rotate. The gear 212 transmits power to multiple toothed blocks 213, causing the two sliding plates 202 to slide out from inside the fixed track 201. The two first arc-shaped plates 204 eventually engage with each other using the locking blocks 205 and slots 206. It is important to note that even when the baffle 211 swings to its lowest point under its own weight, the gear 212 remains engaged with the toothed blocks 213. During this process, the connecting rod 312 moves along with the first arc-shaped plates 204. The connecting rod 312 will contact the arc surface of the circular tube 216. One of the second springs 311 is in a compressed state. At this time, two situations will occur. First, as the circular tube 216 continues to move downward, the connecting rod 312 will be aligned with one of the spiral grooves 315. The compressed second spring 311 will rebound, causing the connecting rod 312 to drive the connecting block 313 to slide into one of the spiral grooves 315. As the circular tube 216 moves downward, the connecting rod 312 slides along the inner wall of the spiral groove 315, causing the two merged first arc plates 204 to rotate. Second, the connecting rod 312 is between two adjacent spiral grooves 315. Since the spiral grooves 315 are spiral-shaped, as the circular tube 216 continues to move downward, when the connecting block 313 is in the spiral groove 315... When the anchor bolt mold 101 is in the correct position, the compressed second spring 311 rebounds, and the connecting rod 312 drives the connecting block 313 to slide into one of the spiral grooves 315. As the circular tube 216 moves downward, the connecting rod 312 slides along the inner wall of the spiral groove 315, causing the two merged first arc-shaped plates 204 to rotate. Under the action of the limiting groove 308, the inner wall of the limiting groove 308 will press against the positioning plate 304, and all four positioning plates 304 will extend simultaneously. At this time, the first spring 306 is in a deformed state, and the positioning plate 304 will press against the circular tube 216, causing the circular tube 216 to shift and move to the center position, achieving the effect of placing the bottom of the anchor bolt mold 101 at the center of the sleeve 105. Since the circular tube 216 and the anchor bolt mold 101 are integrated,The connecting rod 312 is located inside the spiral groove 315. When the position of the circular tube 216 changes, the position of the connecting rod 312 will also change accordingly. The connecting rod 312 will drive the rectangular block 310 to move inside the square groove 309. The second spring 311 will be compressed and deformed. The second spring 311 will stabilize the rectangular block 310 inside the square groove 309, preventing the rectangular block 310 from falling out of the square groove 309.

[0061] Next, concrete can be poured into the sleeve 105. After the standard curing period, ensure that the concrete strength meets the requirements. Before demolding, check whether the surface of the demolding template is flat and smooth, and conduct a trial demolding to check whether the application of the release agent and the state of the concrete surface meet the requirements. During demolding, pull the magnet plate 210. At this time, the rotating rod 208 drives the gear 212 to rotate in the opposite direction, which drives the tooth block 213, so that the two first arc plates 204 separate from each other to facilitate demolding. Then, remove the anchor mold 101 and the polyethylene foam hollow thin tube as a whole. Tools such as hydraulic tools can be used to assist in demolding. After demolding, if some polyethylene foam is stuck to the concrete, physical methods such as using a knife can be used to pry the foam to separate it from the concrete. After demolding, check the quality of the concrete surface. If there are any defects, repair them in time. At the same time, clean and flatten the surface of the mold. If there is any damage or rough edges, repair them in time to prepare for the next use.

[0062] Next, the anchor bolt mold 101 is taken out, the anchor bolt is placed between the first clamping plate 402 and the second clamping plate 403 and tightened. Then, following the above steps, the anchor bolt is inserted into the center position of the pre-reserved anchor hole in the sleeve 105, and the sleeve 105 is filled with anchoring agent. The first motor 102 is started by the external power controller, and through the transmission box 103, the three-jaw chuck 104 drives the sleeve 105 to rotate. The three-jaw chuck 104 is controlled to rotate at a low speed, and at the same time, the elevator 4 is controlled to drive the anchor bolt to slowly descend to the bottom of the sleeve 105. The preparation of the anchor solid sample is completed.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
