Description

Technical Field

[0001] This utility model relates to the field of pipeline blasting technology, and in particular to a device suitable for fixing vibration monitoring sensors for pipeline blasting. Background Technology

[0002] In pipeline construction and operation, monitoring pipeline blasting vibration is a crucial step in ensuring construction safety and pipeline structural stability. Accurate monitoring of blasting vibration signals allows for effective assessment of the impact of blasting operations on surrounding pipelines and the environment, providing important data for optimizing blasting parameters and mitigating safety risks. Existing sensor mounting devices for pipeline blasting vibration monitoring are mostly fixed in location. Due to the influence of the blasting point location and pipeline routing, sensors need to be positioned at different angles to obtain more comprehensive and accurate vibration data. This results in fixed-position sensors lacking effective adjustment mechanisms, making it impossible to flexibly adjust their position according to monitoring needs, thus reducing monitoring accuracy. Therefore, this invention proposes a device suitable for fixing sensors in pipeline blasting vibration monitoring. Utility Model Content

[0030] Embodiment

[0031] As Figure 1 and Figure 2 As shown, a device suitable for fixing a pipeline blasting vibration monitoring sensor proposed by the present utility model includes: a frame 1. The frame 1 is arranged in a "冂"-shaped structure. A bidirectional threaded rod 2 is rotatably arranged between the frames 1 through bearings. The "冂"-shaped structure can stably support the bidirectional threaded rod 2 to ensure stable rotation. One end of the bidirectional threaded rod 2 penetrates through the frame 1 and extends to be connected with a rotating cap 3, and the bidirectional threaded rod 2 can be rotated stably between the frames 1 by rotating the rotating cap 3.

[0032] Furthermore, a set of fixing components 4 for clamping the pipeline is threadedly sleeved on the outer wall of the bidirectional threaded rod 2. The fixing components 4 include a set of threaded sleeve blocks 41 threadedly sleeved on the outer wall of the bidirectional threaded rod 2. By rotating the bidirectional threaded rod 2, the threaded sleeve blocks 41 can be driven to move relatively or oppositely at the same time. One end of each threaded sleeve block 41 is fixedly connected with an arc-shaped clamping plate 42. The arc-shaped clamping plate 42 can closely adhere to the outer wall of the pipeline to ensure the stability of clamping. Rubber pads 8 are respectively fixedly arranged on the inner ring surfaces of the arc-shaped clamping plates 42. The rubber pads 8 not only enhance the friction with the pipeline to prevent sliding, but also can effectively isolate external stray vibrations to ensure the accuracy of data acquisition. One end of the arc-shaped clamping plate 42 is fixedly connected with a fixing block 43. A limiting bolt 44 is threadedly penetrated between the fixing blocks 43. By cooperating the limiting bolt 44 with the fixing blocks 43, one end of the arc-shaped clamping plate 42 can be stably limited.

[0033] As Figure 1 and Figure 3 As shown, a connecting block 5 is fixedly installed on one side of the frame 1. An adjustment component 6 for monitoring pipeline burst vibration is fixedly installed at one end of the connecting block 5. The adjustment component 6 includes an arc-shaped plate 61 fixedly installed at one end of the connecting block 5. A slot 9 is opened on the outer ring surface of the arc-shaped plate 61. A guide groove 62 is opened on the arc-shaped plate 61. A guide frame 63 is slidably installed inside the guide groove 62, which allows the guide frame 63 to move according to the direction of the guide groove 62, thereby ensuring the accurate direction of sensor movement. A fixing post 64 is movably inserted through the guide frame 63. A pull cap is fixedly installed at the upper end of the fixing post 64. The lower end is fixedly connected to a limiting plate 65, and the limiting plate 65 is located between the guide frame 63 and the guide groove 62. The outer wall of the fixing post 64 is fixedly sleeved with a fixing sleeve plate 66. The inner ring surface of the fixing sleeve plate 66 is fixedly provided with a locking block 10, which can be engaged with the locking groove 9 on the arc plate 61. The outer wall of the fixing post 64 is sleeved with a first spring 67. One end of the first spring 67 is fixedly connected to the guide frame 63, and the other end of the first spring 67 is fixedly connected to the limiting plate 65. Through the elastic force of the first spring 67, the locking block 10 on the bottom surface of the fixing sleeve plate 66 can be stably engaged with the locking groove 9 on the arc plate 61.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, a limiting component 7 for fixing the sensor is provided on one side of the adjusting component 6. The limiting component 7 includes a connecting plate 71 fixedly disposed on one side of the guide frame 63. A pull rod 72 is movably disposed through the connecting plate 71. A protective shell 73 is fixedly connected to the lower end of the pull rod 72. The protective shell 73 can protect the sensor and prevent the sensor from being damaged during the explosion. A bolt 74 is threaded through the outer wall of the protective shell 73. One end of the bolt 74 is rotatably connected to a limiting block 75 through a bearing, which can stably limit the sensor inside the protective shell 73. A limiting collar 76 is fixedly sleeved on the outer wall of the pull rod 72. The limiting collar 76 can limit the pull rod 72. A second spring 77 is sleeved on the outer wall of the pull rod 72. One end of the second spring 77 is fixedly connected to the connecting plate 71, and the other end of the second spring 77 is fixedly connected to the protective shell 73. The second spring 77 can provide pressure to the sensor, which can make the output end of the sensor fit tightly against the outer wall of the pipe.

[0035] The working principle of this embodiment is as follows: First, the upper end of the sensor is placed inside the protective shell 73, and the bolt 74 is rotated. The bolt 74, through its threaded engagement with the protective shell 73, drives the limiting block 75 to move, thereby limiting the sensor placed inside the protective shell 73.

[0036] Subsequently, the operator first places the frame 1 of the device on the outside of the pipe to be monitored, then rotates the rotating cap 3, causing the bidirectional threaded rod 2 to rotate. As a set of threaded sleeves 41 threaded onto the outer wall of the bidirectional threaded rod 2 rotates, they move towards each other, and the arc-shaped clamp 42 connected to the threaded sleeves 41 also moves closer to the pipe. Once the arc-shaped clamp 42 contacts the pipe surface, the rotating cap 3 is rotated further until the arc-shaped clamp 42 tightly clamps the pipe. At this point, further fixation is achieved by the limiting bolts 44 between the fixing blocks 43, ensuring that the arc-shaped clamp 42 stably clamps the pipe. Furthermore, the rubber pad 8 on the inner ring surface of the arc-shaped clamp 42 not only increases the friction with the pipe, making the clamping more stable, but also prevents damage to the pipe surface during clamping. Moreover, for pipes of different diameters, stable clamping can be achieved by adjusting the bidirectional threaded rod 2, greatly enhancing the device's adaptability to different pipe specifications.

[0037] Next, based on the location of the blast point and the pipeline route, the operator first pulls the fixing column 64 upwards. The fixing column 64 drives the fixing sleeve 66 and the limiting plate 65 to move upwards. At this time, the first spring 67 is compressed, and the locking block 10 on the inner ring surface of the fixing sleeve 66 disengages from the locking groove 9 on the outer ring surface of the arc plate 61. Then, the guide frame 63 is pushed, causing it to slide along an arc-shaped trajectory within the guide groove 62 of the arc plate 61, thereby driving the limiting component 7 and the sensor connected to one side of the guide frame 63 to move. When the sensor is adjusted to a suitable monitoring angle, the fixing column 64 is released. Under the elastic force of the first spring 67, the fixing column 64 moves downwards, and the locking block 10 re-engages into the corresponding locking groove 9, thus fixing the guide frame 63 and completing the adjustment of the sensor angle. This allows for flexible adjustment of the monitoring angle, ensuring that the sensor can acquire more comprehensive and accurate vibration data and improving monitoring accuracy.

[0038] During the final monitoring, the protective shell 73 is pushed vertically downward by the elastic force of the second spring 77. The protective shell 73 causes the internally fixed sensor to fit tightly against the outer wall of the pipe, thereby monitoring the vibration stability of the pipe during the blasting process.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
