Description

Technical Field

[0001] The present invention relates to the technical field of blasting, in particular to a vibration monitoring device dedicated to blasting. Background Art

[0002] With the rapid development of mining, railway and water conservancy construction, urban excavation, and building demolition, blasting has become a core method for efficient rock breaking and structure demolition. However, blasting vibration waves pose significant safety risks. 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 real-time monitoring of parameters such as vibration speed and frequency during blasting operations to ensure that the impact on the surrounding environment is controllable.

[0003] In this context, the traditional method of manually estimating vibration values ​​based on blasting charge and distance is no longer able to meet the requirements of accuracy and compliance. Dedicated vibration monitoring devices are urgently needed to enable real-time data collection and analysis. However, existing monitoring devices often rely on bolts for fastening. Blasting sites are often composed of complex materials such as rock, soil, and concrete. If the bolts are not drilled deep enough, the hole diameter is off, or they are exposed to long-term blasting shock vibrations, they are prone to loosening, making it difficult to maintain stable vibration transmission.

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

[0005] The purpose of the present invention is to provide a vibration monitoring device specifically for blasting. By providing a mounting portion, the present invention solves the problem that most traditional monitoring devices rely on bolts for fixation during use. However, blasting sites are mostly complex carriers such as rock, soil, and concrete. If the drilling depth is insufficient or the hole diameter deviates during bolt installation, or the device is affected by blasting impact vibration for a long time, the bolts are likely to loosen, making it difficult to maintain a stable vibration transmission state.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a vibration monitoring device specially used for blasting, comprising a vibration monitor and a connecting line arranged on the vibration monitor, and further comprising: a mounting part, wherein a plurality of mounting parts are provided, and the plurality of mounting parts are all installed on the vibration monitor; a fixing part, wherein a plurality of fixing parts are provided, and the plurality of fixing parts are all provided on the vibration monitor; a connecting part, wherein a plurality of connecting parts are provided, and the plurality of connecting parts are all installed on the vibration monitor; the mounting part comprises a connecting assembly, and the connecting assembly is installed on the vibration monitor; and a reset assembly, wherein a plurality of reset assemblies are provided, and the plurality of reset assemblies are all provided on the connecting assembly; the connecting assembly comprises a connecting rod 1 arranged on the right side of the vibration monitor, the bottom of the connecting rod 1 is fixedly connected to a connecting roller, and the inner wall of the connecting roller is fixedly connected to a plurality of connecting rods 2; wherein the connecting rods 2 are distributed on the connecting roller in a circular array.

[0007] Furthermore, the fixing portion includes a limiting component, which is installed on the connecting component; and an inserting component, which is arranged on the limiting component; wherein the limiting component and the inserting component are both located on the outer wall of the connecting rod.

[0008] Furthermore, the connecting portion includes a threaded rod 2 fixedly connected to the top of the connecting rod 1, a connecting plate 2 is provided on the outer wall of the threaded rod 2, the connecting plate 2 is fixed to the vibration monitor on the side away from the threaded rod 2, and a threaded part is provided on the threaded rod 2; wherein, the connecting plate 2 is adapted to the vibration monitor, the connecting plate 2 is sleeved on the outer wall of the threaded rod 2, and the threaded part includes a hexagonal block 2 threadedly connected to the outer wall of the threaded rod 2; wherein, the hexagonal block 2 is in contact with the connecting plate 2.

[0009] Furthermore, the reset assembly includes a limit plate rotatably connected to the outer wall of the second connecting rod, the outer wall of the second connecting rod is sleeved with a conical spring, 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 limit plate; wherein, the end of the limit plate is relatively sharp.

[0010] Furthermore, the limiting assembly includes a hollow rod arranged on the outer wall of a connecting rod, the outer wall of the hollow rod is fixedly connected to a fixing ring, the top of the fixing ring is fixedly connected to a limiting ring, the top of the fixing ring is rotatably connected to a plurality of threaded rods, a plurality of the threaded rods are provided with pressure plates, a plurality of the threaded rods are threadedly connected to the pressure plate, the tops of a plurality of the threaded rods are fixedly connected to a hexagonal block, and a tightening piece is provided on the hexagonal block; wherein, the threaded rod and the pressure plate are distributed in a circular array, the hollow rod is sleeved on the connecting rod, and the tightening piece includes a fastening ring arranged in the pressure plate, and a compensation port is opened on the fastening ring; wherein, the fastening ring is adapted to the pressure plate, and the pressure plate is in contact with the fastening ring.

[0011] Furthermore, the insertion assembly includes a connecting plate 1 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 1; wherein the ends of the tapered rods are tapered.

[0012] The present invention has the following beneficial effects: 1. The present invention provides a mounting portion, firstly opens a mounting hole adapted to the connecting rod 1 at the monitoring target position, and then rotates the connecting rod 1 after being placed in the hole, driving the linked connecting roller to rotate synchronously, providing power for subsequent actions; as the speed of the connecting roller increases, the internal limit plate is thrown out due to centrifugal force to overcome the initial constraint of the conical spring, and at the same time, the conical spring twists and stores energy to form a "throw-out-energy storage" effect; when the limit plate contacts the inner wall of the mounting hole, the connecting rod 1 is quickly reversed, and the conical spring releases potential energy to assist the limit plate in clamping the hole wall to achieve preliminary locking. Continuous reversal can also allow the edge of the limit plate to cut into the soil, completing the transition from "clamping in the hole" to "deep embedding" fixation, and finally achieving the installation of the connecting rod 1, so that the connecting rod 1 forms a high-strength rigid connection with the mounting carrier, eliminating the problem of traditional bolt loosening and signal attenuation of flexible connections, ensuring that the vibration sensor and the carrier vibrate synchronously, and laying the foundation for collecting data such as blasting vibration speed and frequency; 2. The present invention provides a fixing part. After the connecting rod is installed, the installation hole is filled to eliminate the gap in the hole to enhance the stability of the foundation. Then, the hollow rod, the fixing ring and the connecting plate are sequentially put on the connecting rod. When the connecting plate is pressed downward, the tapered rod connected to it is inserted into the soil. The anchoring effect of the tapered structure provides stable support for subsequent fixing components. Then, the fixing ring is put on the hollow rod, and the hexagonal block is rotated to drive the threaded rod to move synchronously, thereby pushing the pressure plate downward. In the process, the hexagonal block is rotated diagonally to move the threaded rod. The camming mechanism of the screw thread is used to move the screw thread of the connecting rod to the soil carrier, thereby preventing the pressure plate from getting stuck due to uneven force. As the pressure plate continues to move downward, an inward squeezing force is generated on the fastening ring, causing the fastening ring to gradually shrink. At this time, the compensation port slowly becomes smaller as the fastening ring shrinks, and the shape of the fastening ring is adaptively adjusted to adapt to the tightening requirements. Finally, the fastening ring is in close contact with the connecting rod 1 during continuous contraction, achieving a rigid fixation of the hollow rod and the connecting rod 1, achieving the goal of preventing the connecting rod 1 from rotating, greatly improving the bonding strength between the fixed structure and the soil carrier, avoiding fixation failure caused by loose carrier, and providing solid support for subsequent locking of the connecting rod. 3. The present invention provides a connecting portion. After completing the fixation of the connecting rod 1 and the hollow rod, the connecting plate 2 provided with the vibration monitor is first aligned with the preset threaded rod 2 on the connecting rod 1. Through the precise adaptation of the mounting hole of the connecting plate 2 and the threaded rod 2, the connecting plate 2 is stably sleeved on the threaded rod 2 to ensure that the vibration monitor is in the preset installation position; then the hexagonal block 2 is threadedly connected to the threaded rod 2. With the help of the threaded structure of the hexagonal block 2, the hexagonal block 2 is rotated by a tool or manually to move it downward along the thread track of the threaded rod 2, gradually squeezing the connecting plate 2; when the hexagonal block 2 is tightened to fit tightly with the connecting plate 2, the self-locking property and squeezing force of the threaded connection are utilized to firmly fix the connecting plate 2 on the threaded rod 2, thereby realizing the rigid connection between the vibration monitor and the connecting rod 1, completing the fixing operation of the entire instrument, and being able to quickly guide the vibration monitor to find the correct installation position, avoiding the sensor angle deviation caused by the instrument offset in the traditional installation, and ensuring that the three-axis vibration sensor of the vibration monitor is consistent with the monitoring target direction, laying the foundation for the accuracy of data acquisition.
