Description

Technical Field

[0001] This invention relates to the field of blasting technology, specifically to a vibration monitoring device for blasting. Background Technology

[0002] With the rapid development of mining, railway and water conservancy construction, urban excavation, and building demolition, blasting operations have become a core method for efficient rock breaking and demolition. However, blasting vibration waves pose significant safety hazards: First, if the vibration waves exceed the tolerance threshold of surrounding buildings and structures, they can easily cause wall cracking, foundation settlement, and even irreversible damage to ancient cultural relics and underground pipelines; second, national standards such as the "Safety Regulations for Blasting" GB6722-2014 clearly require that blasting operations must monitor parameters such as vibration velocity and frequency in real time to ensure that the impact on the surrounding environment is controllable.

[0003] Against this backdrop, the traditional method of relying on manual estimation and calculating vibration values ​​based on explosive charge and distance can no longer meet the requirements for accuracy and compliance. There is an urgent need for dedicated vibration monitoring devices to achieve real-time data acquisition and analysis. However, existing monitoring devices mostly rely on bolt fixation. Blasting sites are often complex environments such as rock, soil, and concrete. If the drilling depth is insufficient, the hole diameter is off, or the devices are subjected to long-term blasting impact vibration, the bolts are prone to loosening, making it difficult to maintain a stable vibration transmission state.

[0004] In view of this, the inventor has specially innovated a vibration monitoring device for blasting. Summary of the Invention

[0005] The purpose of this invention is to provide a vibration monitoring device specifically for blasting. By setting up an installation part, it solves the problem that most traditional monitoring devices rely on bolts for fixation during use. However, blasting sites are often complex carriers such as rock, soil, and concrete. If the drilling depth is insufficient, the hole diameter is deviated, or the device is subjected to long-term blasting impact vibration, the bolts are prone to loosening, making it difficult to maintain a stable vibration transmission state.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a vibration monitoring device for blasting applications, comprising a vibration monitor and a connecting line mounted on the vibration monitor. It also includes: a mounting section, comprising several mounting sections all mounted on the vibration monitor; a fixing section, comprising several fixing sections all mounted on the vibration monitor; a connecting section, comprising several connecting sections all mounted on the vibration monitor; the mounting section includes a connecting assembly mounted on the vibration monitor; and a reset assembly, comprising several reset assemblies all mounted on the connecting assembly. The connecting assembly includes a first connecting rod located on the right side of the vibration monitor, with a connecting roller fixedly connected to the bottom of the first connecting rod, and several second connecting rods fixedly connected to the inner wall of the connecting roller; wherein the second connecting rods are arranged in a circumferential array on the connecting roller.

[0008] Furthermore, the fixing part includes a limiting component mounted on the connecting component; and an insertion component disposed on the limiting component; wherein both the limiting component and the insertion component are located on the outer wall of the connecting rod.

[0009] Furthermore, the connecting part includes a threaded rod two fixedly connected to the top of the connecting rod one, and a connecting plate two is provided on the outer wall of the threaded rod two. The side of the connecting plate two away from the threaded rod two is fixed to the vibration monitoring instrument, and a threaded component is provided on the threaded rod two; wherein, the connecting plate two is adapted to the vibration monitoring instrument, and the connecting plate two is sleeved on the outer wall of the threaded rod two, and the threaded component includes a hexagonal block two threadedly connected to the outer wall of the threaded rod two; wherein, the hexagonal block two is in contact with the connecting plate two.

[0010] Furthermore, the reset assembly includes a limiting plate rotatably connected to the outer wall of the second connecting rod. A conical spring is sleeved on the outer wall of the second connecting rod. The top of the conical spring is fixedly connected to the connecting roller, and the bottom of the conical spring is fixedly connected to the limiting plate. The end of the limiting plate is relatively sharp.

[0011] Furthermore, the limiting component includes a hollow rod disposed on the outer wall of the connecting rod, a fixing ring fixedly connected to the outer wall of the hollow rod, a limit ring fixedly connected to the top of the fixing ring, a plurality of threaded rods rotatably connected to the top of the fixing ring, a pressure plate disposed on the plurality of threaded rods, the plurality of threaded rods being threadedly connected to the pressure plate, and a hexagonal block being fixedly connected to the top of the plurality of threaded rods, the hexagonal block being disposed on the hexagonal block; wherein, the threaded rods and the pressure plate are arranged in a circumferential array, the hollow rod is sleeved on the connecting rod, and the tightening component includes a fastening ring disposed within the pressure plate, the fastening ring having a compensation opening; wherein, the fastening ring is adapted to the pressure plate, and the pressure plate is in contact with the fastening ring.

[0012] Furthermore, the insertion assembly includes a connecting plate fixedly connected to the outer wall of the hollow rod, and a plurality of tapered rods are fixedly connected to the bottom of the connecting plate; wherein the ends of the tapered rods are tapered.

[0013] The present invention has the following beneficial effects:

[0014] 1. This invention, through the installation part, first opens an installation hole at the monitoring target position that matches the connecting rod. After the connecting rod is placed into the hole and rotated, it drives the linked connecting roller to rotate synchronously, providing power for subsequent actions. As the rotation speed of the connecting roller increases, the internal limiting plate is thrown out due to centrifugal force overcoming the initial constraint of the conical spring. At the same time, the conical spring twists and stores energy, forming a "throw-out-energy storage" effect. When the limiting plate contacts the inner wall of the installation hole, the connecting rod is quickly reversed. The conical spring releases potential energy to assist the limiting plate in clamping the hole wall to achieve initial locking. Continuous reversal can also allow the edge of the limiting plate to cut into the soil, completing the fixation from "clamping in the hole" to "deep embedding". Finally, the installation of the connecting rod is achieved, allowing the connecting rod to form a high-strength rigid connection with the installation carrier, eliminating the problems of traditional bolt loosening and signal attenuation of flexible connections, ensuring that the vibration sensor vibrates synchronously with the carrier, and laying the foundation for collecting data such as blasting vibration speed and frequency.

[0015] 2. This invention, by setting a fixing part, fills the mounting hole after the connecting rod is installed to eliminate gaps and enhance foundation stability. Then, the hollow rod, fixing ring, and connecting plate are sequentially fitted onto the connecting rod. When the connecting plate is pressed down, the tapered rod connected to it inserts into the soil, providing stable support for subsequent fixing components through the anchoring effect of the tapered structure. Subsequently, the fixing ring is fitted onto the hollow rod, and rotating the hexagonal block causes the threaded rod to move synchronously, thereby pushing the pressure plate downwards. During this process, the diagonal rotation of the hexagonal block... This process prevents the pressure plate from jamming due to uneven force. As the pressure plate continues to move downward, it exerts an inward squeezing force on the fastening ring, causing the fastening ring to gradually shrink. At this time, the compensation port gradually shrinks with the shrinking of the fastening ring, adaptively adjusting the shape of the fastening ring to meet the tightening requirements. Finally, the fastening ring makes tight contact with the connecting rod 1 during continuous shrinkage, achieving rigid fixation between the hollow rod and the connecting rod 1, thus preventing the connecting rod 1 from rotating. This significantly improves the bonding strength between the fixing structure and the soil carrier, avoiding fixation failure due to loose carrier, and providing solid support for subsequent locking of the connecting rod.

[0016] 3. This invention, by setting a connecting part, after fixing the connecting rod one and the hollow rod, first aligns the connecting plate two of the vibration monitor with the pre-set threaded rod two on the connecting rod one. Through the precise fit between the mounting hole of the connecting plate two and the threaded rod two, the connecting plate two is stably fitted onto the threaded rod two, ensuring that the vibration monitor is in the preset installation position. Then, the hexagonal block two is threadedly connected to the threaded rod two. With the help of the threaded structure of the hexagonal block two, the hexagonal block two is rotated by tools or manually, causing it to move downwards along the threaded trajectory of the threaded rod two, gradually squeezing the connecting plate two. When the hexagonal block two is tightened to fit tightly with the connecting plate two, the self-locking property and squeezing force of the threaded connection are used to firmly fix the connecting plate two onto the threaded rod two, thereby achieving a rigid connection between the vibration monitor and the connecting rod one, completing the entire instrument fixing operation. This can quickly guide the vibration monitor to find the correct installation position, avoiding sensor angle deviation caused by instrument offset in traditional installation, ensuring that the three-dimensional vibration sensor of the vibration monitor is consistent with the monitoring target direction, and laying the foundation for the accuracy of data acquisition.

The end of the limiting plate 221 is relatively sharp. By setting the mounting part 2, the problem of loosening of traditional bolts and signal attenuation of flexible connection are eliminated, ensuring that the vibration sensor vibrates synchronously with the carrier, laying the foundation for collecting data such as blasting vibration speed and frequency.

[0031] The fixing part 3 includes a limiting component 31, which is mounted on the connecting component 21; and an insertion component 32, which is disposed on the limiting component 31. Both the limiting component 31 and the insertion component 32 are located on the outer wall of the connecting rod 211. The limiting component 31 includes a hollow rod 311 disposed on the outer wall of the connecting rod 211. A fixing ring 312 is fixedly connected to the outer wall of the hollow rod 311. A limit ring 313 is fixedly connected to the top of the fixing ring 312. A plurality of threaded rods 314 are rotatably connected to the top of the fixing ring 312. A pressure plate 315 is disposed on each of the threaded rods 314. Each of the threaded rods 314 is threadedly connected to the pressure plate 315. A hexagonal block 316 is fixedly connected to the top of each of the threaded rods 314. The 16 is equipped with a tightening component; wherein, the threaded rod 314 and the pressure plate 315 are arranged in a circumferential array, the hollow rod 311 is sleeved on the connecting rod 211, the insertion assembly 32 includes a connecting plate 321 fixedly connected to the outer wall of the hollow rod 311, and several tapered rods 322 are fixedly connected to the bottom of the connecting plate 321; wherein, the end of the tapered rod 322 is tapered, the tightening component includes a fastening ring 317 disposed in the pressure plate 315, and the fastening ring 317 is provided with a compensation port 318; wherein, the fastening ring 317 is adapted to the pressure plate 315, and the pressure plate 315 is in contact with the fastening ring 317. By setting the fixing part 3, the bonding strength between the fixing structure and the soil carrier is greatly improved, avoiding fixing failure caused by the loosening of the carrier, and providing solid support for the subsequent locking of the connecting rod.

[0032] The connecting part 4 includes a threaded rod 411 fixedly connected to the top of the connecting rod 211. A connecting plate 412 is provided on the outer wall of the threaded rod 411. The side of the connecting plate 412 away from the threaded rod 411 is fixed to the vibration monitor 111. A threaded component is provided on the threaded rod 411. The connecting plate 412 is adapted to the vibration monitor 111 and is sleeved on the outer wall of the threaded rod 411. The threaded component includes a hexagonal block 413 threadedly connected to the outer wall of the threaded rod 411. The hexagonal block 413 is in contact with the connecting plate 412. By setting the connecting part 4, the vibration monitor 111 can be quickly guided to find the correct installation position, avoiding sensor angle deviation caused by instrument offset in traditional installation, ensuring that the three-dimensional vibration sensor of the vibration monitor 111 is consistent with the direction of the monitoring target, and laying the foundation for the accuracy of data acquisition.

[0033] In use, first, four mounting holes are made at the location to be tested. Then, the connecting rod 211 is placed into the mounting holes. Next, the connecting rod 211 is rotated. As the connecting rod 211 rotates, the connecting roller 212 also rotates. When the connecting roller 212 rotates, centrifugal force throws out the limiting plate 221. When the limiting plate 221 is thrown out, the conical spring 222 is twisted, and then quickly reverses direction. During this reversal, the limiting plate 221 gets stuck in the mounting holes. The reversal continues. When connecting rod 211 is installed, the limiting plate 221 will be deeply inserted into the soil, thus achieving the installation effect of connecting rod 211. After installing connecting rod 211, fill the mounting hole, then put hollow rod 311, fixing ring 312 and connecting plate 321 onto connecting rod 211, and then press connecting plate 321 down. At this time, tapered rod 322 will be inserted into the soil. Then put fixing ring 312 onto hollow rod 311, and then rotate hexagonal block 3. 16. At this time, the threaded rod 314 will move downwards along with the pressure plate 315. The diagonally rotating hexagonal block 316 prevents the pressure plate 315 from jamming. As the pressure plate 315 continues to move downwards, it will press the fastening ring 317 inwards. As the fastening ring 317 is compressed, it will contract. During this contraction, the compensation port 318 will gradually decrease to accommodate the tightening of the fastening ring 317. As the fastening ring 317 continues to tighten, it will engage with the connecting rod 2. 11. Make contact, thereby fixing the hollow rod 311 and the connecting rod 211 together, thus preventing the connecting rod 211 from rotating. Then, align the connecting plate 412 on the vibration monitor 111 with the threaded rod 411 on the connecting rod 211. After the connecting plate 412 is fitted onto the threaded rod 411, thread the hexagonal block 413 onto the threaded rod 411. Tighten the hexagonal block 413 to fix the vibration monitor 111.

Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
