Description

Technical Field

[0001] This utility model relates to the field of building vibration monitoring technology, and in particular to a vibration monitoring sensor fixing device. Background Technology

[0002] As a vital transportation hub connecting the sea and land, the safety and stability of port infrastructure are crucial for ensuring the normal operation of the port. Among these, buildings play a pivotal role, serving not only as places for people to live, work, study, produce, operate businesses, entertain, store goods, and conduct other social activities, but also as important components of the port's landscape and landmarks. However, due to the frequent impact of surrounding heavy-duty transport vehicles, coupled with the complex geological and climatic conditions of the port, these buildings face safety hazards such as cracking and deformation caused by vibration. Conventional building assessment techniques primarily target the current state of existing buildings, rather than the process by which potential hazards arise. However, the damage caused by vibration to buildings is often a continuous process; by the time it is detected, the damage has already occurred. Therefore, long-term vibration monitoring of port buildings is extremely important for assessing the impact of vibration on buildings.

[0003] Currently, after conventional vibration monitoring sensors are installed, the data collected is inaccurate due to the sensor not fitting tightly to the concrete structure and the deviation between the installation angle and the sensor's set acquisition angle. Over time, this can even lead to the sensor fixing device loosening or falling off.

[0004] Therefore, a vibration monitoring sensor mounting device is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a vibration monitoring sensor fixing device. By adopting a U-shaped fixing frame and a fixing bolt screw connection design between the fixing frame and the concrete structure, combined with the function of a universal level and adjusting bolts, it can ensure that the sensor maintains continuous and tight contact with the concrete structure, significantly reducing the problems of sensor loosening and inaccurate angle, and improving the continuity and reliability of data acquisition.

[0006] A vibration monitoring sensor mounting device includes a U-shaped mounting frame, fixing bolts, multiple front adjustment bolts, and two side adjustment bolts. The U-shaped mounting frame has two fixing plates, two side plates, and a top plate. The two fixing plates are fixed to the lower ends of the two side plates, and the two ends of the top plate are fixed to the upper ends of the two side plates. Two fixing bolts are installed on the two fixing plates of the U-shaped mounting frame to connect the U-shaped mounting frame to a concrete structure. The multiple front adjustment bolts are installed on the top plate of the U-shaped mounting frame. The two side adjustment bolts are symmetrically installed on the two side plates of the U-shaped mounting frame.

[0007] Furthermore, it also includes a universal level, which is mounted on the top plate.

[0008] Furthermore, there are three front adjustment bolts arranged in a triangle, and the universal level is installed between the three front adjustment bolts.

[0009] Furthermore, pads are installed on the end faces of both the front and side adjusting bolts that contact the vibration monitoring sensor.

[0010] Furthermore, the fixing bolts are expansion bolts.

[0011] Furthermore, anti-vibration pads are installed on the expansion bolts.

[0012] The advantages and beneficial effects of this utility model are:

[0013] 1. This utility model's U-shaped mounting bracket allows vibration monitoring sensors to be tightly attached to the side of concrete structural members, thereby improving the accuracy and consistency of monitoring data. This precise fit is especially crucial for detecting small amplitude vibrations.

[0014] 2. This utility model has pads installed on the end faces of the front and side adjusting bolts that contact the vibration monitoring sensor. With the help of a universal level, it can ensure that the vibration monitoring sensor maintains continuous and tight contact with the concrete structure, which significantly reduces the problems of loose vibration monitoring sensor and inaccurate angle, and improves the continuity and reliability of data acquisition.

[0015] 3. This utility model installs anti-vibration pads on the exposed threads of the fixing bolt. The disconnected anti-vibration pads can improve the anti-vibration performance. By adjusting the screwing depth of the fixing bolt, it is suitable for vibration monitoring sensors of various sizes and models. Attached Figure Description

Detailed Implementation

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] like Figures 1-3 The vibration monitoring sensor fixing device shown is used to make the vibration monitoring sensor 12 fit tightly against the concrete structure component 11. The fixing device includes a U-shaped fixing frame, fixing bolts 6, three front adjusting bolts 2, two side adjusting bolts 5, and a universal level 10.

[0025] The U-shaped fixing frame provides vertical stability. It has two fixing plates 9, two side plates 4, and a top plate 1. The two fixing plates 9 are fixed to the lower ends of the two side plates 4, and the two ends of the top plate 1 are fixed to the upper ends of the two side plates 4. Two fixing bolts 6 are installed on the two fixing plates 9 of the U-shaped fixing frame, connecting the U-shaped fixing frame to the concrete structure 11. Anti-vibration washers 8 and nuts 7 are sequentially installed on the exposed threads of the fixing bolts 6. The fixing plates 9 are fixed by rotating the nuts 7. The discontinuous anti-vibration washers 8 improve vibration damping performance and prevent the nuts 7 from loosening due to frequent vibration. Various sizes and models of vibration monitoring sensors 12 can be accommodated by adjusting the screw depth of the fixing bolts 6. The U-shaped fixing frame is a U-shaped steel frame. The fixing bolts 6 are expansion bolts.

[0026] The front adjusting bolt 2 and the side adjusting bolt 5 provide horizontal stability, ensuring the correct positioning of the vibration monitoring sensor 12 on the side of the concrete structure 11 and preventing displacement. Three front adjusting bolts 2 are installed on the top plate 1 of the U-shaped fixing frame in a triangular arrangement; two side adjusting bolts 5 are symmetrically installed on the two side plates 4 of the U-shaped fixing frame. Pads 3 are installed on the end faces of the front adjusting bolts 2 and the side adjusting bolts 5 that contact the vibration monitoring sensor 12. The fit between the front adjusting bolts 2 and the side adjusting bolts 5 and the vibration monitoring sensor 12 can be adjusted by screwing the pads 3 into the bolts.

[0027] The universal level 10 is installed between the three front adjustment bolts 2. In conjunction with the universal level 10, the front adjustment bolts 2 and the side adjustment bolts 5 ensure that the vibration monitoring sensor 12 maintains continuous and tight contact with the concrete structure 11, which significantly reduces the problems of loosening and inaccurate angle of the vibration monitoring sensor 12 and improves the continuity and reliability of data acquisition.

[0028] like Figures 4-5 The diagram shows the usage state of the vibration monitoring sensor 12 fixing device of this utility model. The U-shaped fixing frame is fixed at an appropriate position on the side of the concrete structure 11. Then, the vibration monitoring sensor 12 is fixed on the side of the concrete structure 11. The fixing bolt 6 is tightened to make the vibration monitoring sensor 12 fit between the U-shaped fixing frame and the concrete structure 11. The front adjusting bolt 2 and the side adjusting bolt 5 are adjusted to fix the vibration monitoring sensor 12 between the U-shaped fixing frame. Finally, the universal level 10 is adjusted to the center horizontal position and the nut 7 is tightened to make the vibration monitoring sensor 12 and the concrete structure 11 fit tightly together.

[0029] In this invention, the U-shaped fixing bracket is threadedly connected to the concrete structure 11 by fixing bolts 6. The front adjusting bolts 2 and the side adjusting bolts 5 ensure that the vibration monitoring sensor 12 is firmly pressed onto the concrete structure 11 at all times. This design effectively transmits pressure, ensuring that there is no gap between the vibration monitoring sensor 12 and the concrete structure 11, and maintaining good contact even when the concrete structure 11 vibrates or deforms.

[0030] This utility model features a universal level 10 mounted on a U-shaped fixing frame, with a vibration monitoring sensor 12 installed inside the U-shaped fixing frame. The level bubble on the U-shaped fixing frame ensures that the vibration monitoring sensor 12 can be stably installed at a predetermined position on the side of the concrete structure 11, avoiding inaccurate monitoring data due to installation deviations and improving the sensitivity and accuracy of monitoring.

[0031] The U-shaped fixing bracket in this invention is a key component of the entire fixing device. It is connected to the concrete structure 11 via a threaded connection, allowing the operator to adjust the position of the fixing bolt 6 by rotation, thereby controlling the pressure exerted by the vibration monitoring sensor 12 on the concrete structure 11. The U-shaped structure design makes it easy for the operator to apply force, improving the convenience and flexibility of use.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
