Description

Technical Field

[0001] This utility model relates to the field of bridge construction and maintenance technology, specifically to a high-precision bridge vibration sensing device fixture. Background Technology

[0002] In bridge engineering, high-precision bridge vibration sensing devices play a crucial role in the safety monitoring, maintenance, and management of bridges. These devices can collect bridge vibration data in real time, including vibration amplitude and frequency. Typically, such devices consist of high-precision sensors and a data acquisition system. The sensors are installed at key locations on the bridge, such as beams and columns, while the data acquisition system is responsible for collecting, storing, and transmitting the data measured by the sensors. During installation, it is essential to ensure the device maintains a stable working state during bridge vibration, preventing it from loosening or falling off during vibration, and also avoiding any impact on measurement accuracy due to shaking or displacement. Therefore, this invention proposes a high-precision bridge vibration sensing device fixation device.

[0003] According to a search, Chinese patent document CN219368722U discloses a fixing device for strain sensors in bridge monitoring. By setting a fixing bracket and a slot, the strain sensor can be more securely fixed, preventing it from impacting the protective box and causing damage during shaking. Side lugs allow for bolt or pin connections via drilling, or direct welding to the reinforcing steel frame. The sponge reduces stress on the protective box, providing protection and preventing damage due to lack of elasticity. However, this device is cumbersome to install and fix in actual use, and it is not applicable to different sensor models. It is inconvenient to install and disassemble, has low applicability, and reduces overall work efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a high-precision bridge vibration sensing device fixture, which has the advantages of convenient installation, strong applicability, and improved work efficiency, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-precision bridge vibration sensing device fixture, comprising a base, a column fixedly mounted on the top surface of the base, a drive motor fixedly mounted on the top surface of the column, a first sliding groove on the right side of the column, a first threaded rod and a first slider installed inside the first sliding groove, a lifting platform fixedly mounted on the right side of the first slider, a second sliding groove and a third sliding groove on the lifting platform, a second slider installed inside the second sliding groove, a third slider and a bidirectional lead screw installed inside the third sliding groove, a first handle fixedly mounted on the outer end face of the bidirectional lead screw, a baffle fixedly mounted on the top surface of the third slider, a fourth sliding groove on the inner side of the baffle, a second threaded rod and a fourth slider installed inside the fourth sliding groove, a second handle fixedly mounted on the top surface of the second threaded rod, and a pressure plate fixedly mounted on the outer side of the fourth slider.

[0008] Preferably, the first slider is slidably installed inside the first groove, and the first slider is threadedly connected to the outer surface of the first threaded rod, and the output shaft of the drive motor is fixedly connected to the top end of the first threaded rod.

[0009] With the above technical solution, when the drive motor is started, the output shaft of the drive motor can drive the first threaded rod to rotate, and the first threaded rod can then drive the first slider and other parts such as the lifting platform to move in the vertical direction. Therefore, the height position of the sensing device can be effectively adjusted, making it suitable for different working scenarios and improving the overall practicality.

[0010] Preferably, there are two of each of the second slide groove, the third slide groove, the second slider, and the third slider. The second slider is slidably installed inside the second slide groove, and the third slider is slidably installed inside the third slide groove.

[0011] With the above technical solution, when the two second sliders and the two third sliders slide inside the second slide groove and the third slide groove respectively, the second sliders and the third sliders can drive the baffle to move in the horizontal direction, thereby effectively limiting and fixing the position of sensing devices of different sizes, improving the overall stability and applicability.

[0012] Preferably, there are two of each of the bidirectional lead screw and the first handle, and the two second sliders are threaded to the outer surface of one of the bidirectional lead screws, and the two third sliders are threaded to the outer surface of the other bidirectional lead screw.

[0013] By rotating the two first handles, the two first handles can drive the two bidirectional lead screws to rotate. The bidirectional lead screws can then drive the two second sliders and the third slider to move relative to each other, thereby allowing the baffle to initially fix the sensing device. The operation is simple and convenient, improving the overall convenience.

[0014] Preferably, there are four of each of the baffle, the fourth slide groove, the second threaded rod, the fourth slider, the second handle, and the pressure plate, and the fourth slider is slidably installed inside the fourth slide groove and threadedly connected to the outer surface of the second threaded rod.

[0015] By rotating the four second handles, the second handles can drive the second threaded rods to rotate, which in turn can drive the fourth slider and the pressure plate to move vertically. The pressure plate can thus effectively press and fix the sensing devices of different sizes, improving the overall stability and convenience of the device.

[0016] Preferably, rubber pads are provided on the inner sides of the four baffles and the bottom surfaces of the four pressure plates.

[0017] With the above technical solution, when the baffle and pressure plate press and fix the sensing device, the multiple rubber pads can not only increase the friction between the sensing device and the sensing device, but also prevent damage to its surface, thus improving the overall stability and practicality.

[0018] Preferably, the top surface of the base has four mounting holes.

[0019] The above technical solution allows for easy installation and fixation of the device by staff in special environments through four mounting holes, further improving the stability of the device.

[0020] Compared with the prior art, this utility model provides a high-precision bridge vibration sensing device fixture, which has the following advantages:

[0021] 1. This utility model involves rotating two first handles, which in turn drive two bidirectional lead screws to rotate. The bidirectional lead screws then drive two second and third sliders to move relative to each other, thereby initially fixing the sensing device with a baffle. Subsequently, rotating four second handles drives two threaded rods to rotate, which in turn drive a fourth slider and a pressure plate to move vertically. The pressure plate can thus effectively press and fix sensing devices of different sizes, improving the overall stability and convenience of the device.

[0022] 2. By starting the drive motor, the output shaft of the drive motor can drive the first threaded rod to rotate. The first threaded rod can then drive the first slider and other parts such as the lifting platform to move in the vertical direction. Therefore, the height position of the sensing device can be effectively adjusted, making it suitable for different working scenarios and improving the overall practicality.

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.

[0029] Please see Figure 1-4A high-precision bridge vibration sensing device fixture includes a base 1, a column 2 fixedly mounted on the top surface of the base 1, a drive motor 3 fixedly mounted on the top surface of the column 2, a first slide groove 4 on the right side of the column 2, a first threaded rod 5 and a first slider 6 installed inside the first slide groove 4, a lifting platform 7 fixedly mounted on the right side of the first slider 6, a second slide groove 8 and a third slide groove 9 on the lifting platform 7, a second slider 10 installed inside the second slide groove 8, a third slider 11 and a bidirectional lead screw 12 installed inside the third slide groove 9, a first handle 13 fixedly mounted on the outer end face of the bidirectional lead screw 12, a baffle 14 fixedly mounted on the top surface of the third slider 11, a fourth slide groove 15 on the inner side of the baffle 14, a second threaded rod 16 and a fourth slider 17 installed inside the fourth slide groove 15, a second handle 18 fixedly mounted on the top surface of the second threaded rod 16, and a pressure plate 19 fixedly mounted on the outer side of the fourth slider 17.

[0030] Specifically, the first slider 6 is slidably installed inside the first groove 4, and the first slider 6 is threadedly connected to the outer surface of the first threaded rod 5. The output shaft of the drive motor 3 is fixedly connected to the top of the first threaded rod 5. The advantage is that, with this structure, when the drive motor 3 is started, the output shaft of the drive motor 3 can drive the first threaded rod 5 to rotate. The first threaded rod 5 can then drive the first slider 6 and other components such as the lifting platform 7 to move vertically. Therefore, the height position of the sensing device can be effectively adjusted, making it suitable for different working scenarios and improving overall practicality.

[0031] Specifically, there are two of each of the following: the second slide groove 8, the third slide groove 9, the second slider 10, and the third slider 11. The second slider 10 is slidably installed inside the second slide groove 8, and the third slider 11 is slidably installed inside the third slide groove 9. The advantage is that, with this structure, when the two second sliders 10 and the two third sliders 11 slide inside the second slide groove 8 and the third slide groove 9 respectively, the second sliders 10 and the third sliders 11 can drive the baffle 14 to move horizontally. This effectively restricts and fixes the position of sensing devices of different sizes, improving overall stability and applicability.

[0032] Specifically, there are two bidirectional lead screws 12 and two first handles 13. Two second sliders 10 are threadedly connected to the outer surface of one of the bidirectional lead screws 12, and two third sliders 11 are threadedly connected to the outer surface of the other bidirectional lead screw 12. The advantage is that by rotating the two first handles 13, the two first handles 13 can drive the two bidirectional lead screws 12 to rotate. The bidirectional lead screws 12 can then drive the two second sliders 10 and the third sliders 11 to move relative to each other, thereby allowing the baffle 14 to initially fix the sensing device. This simple and convenient operation improves overall ease of use.

[0033] Specifically, four baffles 14, four slide grooves 15, two threaded rods 16, four sliders 17, two handles 18, and four pressure plates 19 are provided. The fourth slider 17 is slidably installed inside the fourth slide groove 15 and threadedly connected to the outer surface of the second threaded rod 16. The advantage is that by rotating the four second handles 18, the second handles 18 can drive the second threaded rods 16 to rotate, which in turn drives the fourth sliders 17 and the pressure plates 19 to move vertically. Therefore, the pressure plates 19 can effectively press and fix sensors of different sizes, improving the overall stability and convenience of the device.

[0034] Specifically, rubber pads 20 are provided on the inner sides of the four baffles 14 and the bottom surfaces of the four pressure plates 19. The advantage is that, with this structure, when the baffles 14 and pressure plates 19 press and fix the sensing device, the multiple rubber pads 20 can not only increase the friction between the sensing device and the device, but also prevent damage to its surface, thus improving the overall stability and practicality.

[0035] Specifically, the top surface of the base 1 has four mounting holes 21. The advantage is that the four mounting holes 21 make it convenient for workers to install and fix the device as a whole in some special environments, further improving the stability of the device.

[0036] In use, rotating the two first handles 13 drives the two bidirectional lead screws 12 to rotate, which in turn drives the two second sliders 10 and the third slider 11 to move relative to each other. This allows the baffle 14 to initially fix the sensing device. Then, rotating the four second handles 18 drives the second threaded rod 16 to rotate, which in turn drives the fourth slider 17 and the pressure plate 19 to move vertically. The pressure plate 19 can thus effectively press and fix sensing devices of different sizes, improving the overall stability and convenience of the device. By starting the drive motor 3, the output shaft of the drive motor 3 drives the first threaded rod 5 to rotate, which in turn drives the first slider 6 and the lifting platform 7 to move vertically. This allows for effective adjustment of the height of the sensing device, making it suitable for different working scenarios and improving its overall practicality.
