Description

Technical Field

[0001] This utility model relates to the field of bridge monitoring technology, and in particular to a mounting bracket for a bridge main tower monitoring sensor. Background Technology

[0002] In bridge structural health monitoring systems, sensors are key front-end devices for sensing structural conditions. The reliability, convenience, and accuracy of their installation directly determine the quality of monitoring data and the effectiveness of the entire system. As the main load-bearing component, the main tower of a bridge is particularly important to monitor, and various sensors, such as accelerometers and inclinometers, are usually installed on the surface of the tower.

[0003] However, these traditional installation methods have revealed many prominent problems in practical applications: when installing on a steel structure, the four lead screws must be precisely aligned and the nuts tightened simultaneously. Any asymmetrical tightening will cause the support base plate to be twisted by force, thus failing to meet the installation reference of some sensors, thereby affecting the sensing accuracy of the sensors.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1:

[0030] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a mounting bracket for a bridge main tower monitoring sensor, including a base plate 1. Each of the four corners inside the base plate 1 is connected with a lead screw 2. A back plate 5 is provided between one end of the four lead screws 2. A nut 3 is threadedly connected to the surface of the end of the lead screw 2 inside the base plate 1.

[0031] When personnel need to install the sensor on the main tower of the bridge for testing, firstly, the back plate 5 is attached to the steel structure surface of the main tower of the bridge. At this time, the four lead screws 2 will surround the side of the steel structure. Then, the personnel bring the base plate 1 close to the steel structure so that the four lead screws 2 are inserted into the interior of the base plate 1. Finally, the movable plate 401 is sleeved between the surfaces of the four lead screws 2 and then tightened with bolts. At this time, the sensor mounting bracket is completed. Finally, the personnel place the sensor on the horizontal surface of the base plate 1 to complete the sensor installation.

[0032] Auxiliary component 4 is disposed in substrate 1;

[0033] The auxiliary component 4 includes a movable plate 401 disposed in the base plate 1, a paddle 403 disposed inside the movable plate 401, and a pressing plate 406 disposed behind the movable plate 401 for increasing the pre-tightening force of the overall support.

[0034] Example 2:

[0035] Reference Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the auxiliary component 4 also includes a through hole 402 formed on the surface of the movable plate 401, through which the lead screw 2 passes and into the through hole 402, and the nut 3 on the surface of the lead screw 2 is in contact with the movable plate 401.

[0037] When the aforementioned movable plate 401 is sleeved on the surface of the four lead screws 2, it can simultaneously limit the position and axial distance of the four lead screws 2, and maintain the angular consistency of the four lead screws 2.

[0038] Specifically, the auxiliary component 4 also includes a groove 404 formed on the surface of the lead screw 2, and a slot 405 is formed in the lower inner part of the groove 404. The paddle 403 is engaged in the slot 405 and its other end is fixedly connected to the inner wall of the through hole 402.

[0039] When the movable plate 401 is sleeved on the surface of the lead screw 2, the paddle 403 in the through hole 402 of the movable plate 401 will first enter the groove 404 of the lead screw 2. The width of the paddle 403 is the same as that of the groove 404, which can limit the path of the movable plate 401.

[0040] Specifically, the paddle 403 and the movable plate 401 are connected as a single unit, and the design angle of the paddle 403 is set opposite to the direction of travel of the movable plate 401.

[0041] When the movable plate 401 moves, the paddle 403, whose angle is opposite to that of the movable plate 401, can be pressed and deformed when it is in contact with the inner lower part of the groove 404, reducing its tilt angle. When the movable plate 401 stops to a certain point, the pressing force disappears, and the paddle 403 will rebound using its own elasticity, so that its end will rebound into the groove 404, which can pre-position the movable plate 401, which is beneficial for personnel to install it step by step later.

[0042] Specifically, a collar 409 with an inner diameter matching that of the perforation 402 is provided inside the movable plate 401 at the perforation 402.

[0043] When the movable plate 401 is inserted, the longer sleeve can slide on the surface of the lead screw 2, thereby increasing the thickness of the movable plate 401 from the side. This allows the movable plate 401 to be limited in angle and position, so that it can only maintain horizontal displacement.

[0044] Example 3:

[0045] Reference Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0046] Specifically, a slot 408 is formed on the surface of the substrate 1, and an extrusion plate 406 is located in the substrate 1. The extrusion plate 406 is designed for horizontal use, and a pressure plate 407 is provided at the corner of the extrusion plate 406, which corresponds to the movable plate 401. The extrusion plate 406 is made of stainless steel and can deform as the extrusion pressure increases. The other two ends of the extrusion plate 406 correspond to the bridge structure. The slot 408 on the surface of the substrate 1 and the extrusion plate 406 have the same curvature and are both arc-shaped.

[0047] After the movable plate 401 moves to a certain position, it contacts the pressure plate 407 of the extrusion plate 406. At this time, the back of the extrusion plate 406 is pressed, and its whole body will extend outward along the groove 408 of the base plate 1. At this time, the other two ends of the extrusion plate 406 will be in contact with the steel structure surface of the main tower of the bridge. As the extrusion pressure continues to increase, the two ends of the extrusion plate 406 will change from oblique movement to vertical movement along the surface of the steel structure, which can improve the pre-tightening force between the base plate 1, the back plate 5 and the steel structure, and ensure the overall stability of the sensor bracket.

[0048] After all the above steps are completed, the personnel can put the nut 3 on the surface of the lead screw 2 and turn it to tighten. Since the exposed end length of each lead screw 2 is the same, the torque difference of the nuts 3 located at the four corners of the base plate 1 will also be kept within the same controllable range.

[0049] In use, first, the back plate 5 is attached to the steel structure surface of the main tower of the bridge. Then, the base plate 1 is brought close to the steel structure so that the four lead screws 2 are inserted into the interior of the base plate 1. Next, the movable plate 401 is horizontally fitted between the four lead screws 2. At this time, the collar 409 can horizontally limit the movable plate 401, keeping its edges and corners on the same axis. When the movable plate 401 is inserted to a certain position, the lever 403 will engage in the slot 405 to pre-position the movable plate 401, so that the exposed connectable ends of the four lead screws 2 are all of the same length. Thus, when the personnel install the nuts 3, they can maintain the torque of each nut 3, ensure the uniform tightness of the installation of the base plate 1 edges and corners, and ensure the sensing accuracy of the sensor. Finally, the personnel place the sensor on the horizontal surface of the base plate 1 to complete the sensor installation.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
