Abstract
Description
Installation structure of damage monitoring box for long-span bridge structures Technical Field
[0001] This utility model relates to the field of bridge monitoring technology, and in particular to the installation structure of a damage monitoring box for long-span bridge structures. Background Technology
[0002] With the acceleration of urbanization and the continuous improvement of transportation infrastructure, long-span bridges are playing an increasingly important role in modern transportation networks. These bridges not only improve traffic flow efficiency but also alleviate pressure on surface traffic to some extent. However, long-span bridges have complex structures, bear large loads, and operate in harsh environments, making them prone to structural damage such as cracks, deformation, and corrosion. These problems directly affect the safety and service life of the bridges; therefore, real-time and effective structural damage monitoring of long-span bridges is particularly important.
[0003] Traditional methods for monitoring bridge structural damage primarily rely on periodic manual inspections. These methods are not only inefficient but also fail to provide real-time and comprehensive information on the bridge's structural condition. In recent years, with the development of sensor and automated monitoring technologies, new monitoring devices have been gradually applied to practical engineering projects. These sensors typically include pressure sensors, temperature sensors, distance sensors, and cameras. A monitoring box is usually installed on the bridge. The sensors transmit the monitored data to the monitoring box, which then integrates the data and sends it to a remote monitoring center. Existing monitoring boxes rely heavily on fasteners for positioning and fixing, requiring multiple fasteners during installation. Furthermore, the fasteners often need to be manually adjusted to ensure hole alignment before installation, making installation cumbersome and inconvenient for subsequent disassembly and maintenance. Summary of the Invention
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an installation structure for a damage monitoring box for long-span bridge structures.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] The installation structure of a damage monitoring box for long-span bridge structures includes: a base plate, fixedly installed on a concrete base, with multiple raised positioning blocks on its upper surface, each positioning block having a positioning groove with an upper opening; a back plate, fixedly installed on the rear side of the base plate, vertically positioned and perpendicular to the base plate, with raised locking blocks on the front surface of the back plate, each locking block having a locking port with an upper opening; a monitoring box, with positioning protrusions embedded in the positioning grooves at the bottom, and an insert block and a limiting block connected to the rear side, the insert block being inserted into the locking port, and the limiting block having a horizontally extending limiting hole; and a limiting member, detachably connected to the back plate, the limiting member partially inserted into the limiting hole.
[0007] Furthermore, the base plate has a first clearance hole in the middle, and four positioning blocks and positioning protrusions are provided accordingly, with the positioning blocks surrounding the first clearance hole.
[0008] Furthermore, a first soft sleeve is embedded in the positioning groove, which is used to wrap the positioning protrusion embedded in the positioning groove.
[0009] Furthermore, a second soft sleeve is embedded in the card slot, which is used to wrap the insert block inserted into the card slot.
[0010] Furthermore, the upper end of the insertion block is provided with an extension block that extends forward and is connected to the rear side wall of the monitoring box, and the extension block is higher than the locking block.
[0011] Furthermore, the insertion block is located on the upper part of the monitoring box, and there are two insertion blocks arranged at intervals on the left and right.
[0012] Furthermore, the limiting block is attached to the side wall of one side of the locking block, and the bottom of the limiting block is lower than the bottom of the locking block.
[0013] Furthermore, a mounting block is provided on the front side of the back plate, the mounting block is provided with a threaded hole, and the limiting member is a screw threaded to the threaded hole.
[0014] Furthermore, the end of the screw is provided with a cylindrical portion for insertion into a limiting hole.
[0015] Furthermore, the back plate is provided with a second clearance hole.
[0016] This utility model has the following beneficial effects:
[0017] By using a positioning protrusion at the bottom of the monitoring box to embed into a positioning groove, and a rear insert block to insert into a locking slot, the monitoring box achieves rapid positioning and limiting. This allows the monitoring box to move only upwards, a single degree of freedom, which is restricted by the limiting component inserted into the limiting hole. This ensures omnidirectional fixation of the monitoring box. Disassembly and installation only require removing and installing the limiting component, reducing the number of fasteners needed during installation. Furthermore, the positioning protrusion embedding into the positioning groove and the insert block inserting into the locking slot enable rapid positioning during installation, ensuring precise alignment of the monitoring box and facilitating the insertion of the limiting component into the limiting hole.

[0034] Please refer to Figures 1 and 2. In a preferred embodiment of the present invention, the installation structure of the damage monitoring box for a long-span bridge structure includes a base plate 100, a back plate 200, a monitoring box 300, and a limiting member 400.
[0035] The base plate 100 is used for fixed installation on the concrete base. Specifically, the base plate 100 has mounting holes 130 at its four corners. Fasteners can be installed in the mounting holes 130 to fix the base plate 100 on the concrete base. The fasteners can be expansion bolts, or threaded sleeves can be pre-embedded in the concrete base, and screws that fit the threaded sleeves can be inserted into the mounting holes 130.
[0036] The upper surface of the base plate 100 is provided with a plurality of protruding positioning blocks 110, and the positioning blocks 110 are provided with positioning grooves 111 with openings at the top.
[0037] The back plate 200 is fixedly installed on the rear side of the base plate 100. The back plate 200 is vertically set and perpendicular to the base plate 100. The front surface of the back plate 200 is provided with a protruding locking block 210, and the locking block 210 is provided with a locking slot 211 with an upper opening.
[0038] The bottom of the monitoring box 300 is provided with a positioning protrusion 310 embedded in the positioning groove 111. The rear side of the monitoring box 300 is connected to an insert block 320 and a limiting block 330. The insert block 320 is inserted into the locking port 211. The limiting block 330 is provided with a horizontally extending limiting hole 331. Specifically, the limiting hole 331 extends horizontally through the limiting block 330 in the left and right direction.
[0039] The limiting member 400 is detachably connected to the back plate 200, and part of the limiting member 400 is inserted into the limiting hole 331.
[0040] In a preferred embodiment of this utility model, the installation structure of a damage monitoring box for a long-span bridge structure is provided. The positioning protrusion 310 at the bottom of the monitoring box 300 is embedded in the positioning groove 111, and the insert block 320 on the rear side is inserted into the locking slot 211. This achieves rapid positioning and limiting of the monitoring box 300. With these structures in place, the monitoring box 300 has only one degree of freedom of movement: upward. This upward movement is restricted by the limiting member 400 inserted into the limiting hole 331, thus achieving omnidirectional fixation of the monitoring box 300. Disassembly and installation of the monitoring box 300 only require disassembling and assembling the limiting member 400, reducing the number of fasteners required during installation. Furthermore, the positioning protrusion 310 embedded in the positioning groove 111 and the insert block 320 inserted into the locking slot 211 achieve rapid positioning during installation, ensuring precise alignment of the monitoring box 300 during installation. This facilitates the alignment of the limiting member 400 into the limiting hole 331. Compared to existing technologies, this utility model embodiment reduces the need for manual adjustment to align the holes before installing fasteners.
[0041] Referring to Figures 2 and 5, in some embodiments of this utility model, four positioning blocks 110 and four positioning protrusions 310 are provided respectively, thereby enabling multi-position positioning and limiting, and improving installation stability. In addition, in order to reduce the weight of the base plate 100 and increase the space at the bottom of the monitoring box 300 to reduce heat accumulation, a first clearance hole 120 is provided in the middle of the base plate 100, and the positioning blocks 110 are arranged around the periphery of the first clearance hole 120.
[0042] Referring to Figures 2 and 5, in some embodiments of this utility model, a first soft sleeve 112 is embedded in the positioning groove 111. The first soft sleeve 112 is used to wrap the positioning protrusion 310 embedded in the positioning groove 111. Through the buffering effect of the first soft sleeve 112, vibration transmitted to the monitoring box 300 is reduced, component damage is reduced, and the durability of the equipment is further improved. The first soft sleeve 112 can be made of rubber. It is understood that the first soft sleeve 112 is clamped by the positioning protrusion 310 and the inner wall of the positioning groove 111 within the positioning groove 111, and it also serves to eliminate installation gaps.
[0043] Referring to Figure 3, in some embodiments of this utility model, a second soft sleeve 212 is embedded in the slot 211. The second soft sleeve 212 is used to wrap the insert 320 inserted into the slot 211. By wrapping the insert 320 inserted into the slot 211, not only is the installation stability of the insert 320 improved and the installation gap eliminated, but also the cushioning effect of the second soft sleeve 212 reduces the vibration transmitted to the monitoring box 300. The second soft sleeve 212 can be made of rubber.
[0044] Referring to Figures 3 and 4, in some embodiments of this utility model, the upper end of the insert block 320 is provided with an extension block 340 that extends forward and is connected to the rear side wall of the monitoring box 300, so that there is a gap between the insert block 320 and the rear side wall of the monitoring box 300 to accommodate the front side wall of the locking port 211, thus avoiding structural interference. The extension block 340 is higher than the locking block 210, thereby preventing the gravity load of the monitoring box 300 from being transmitted through the contact between the extension block 340 and the locking block 210, which would cause stress concentration at the extension block 340 and make it easy to be damaged.
[0045] Referring to Figure 2, in some embodiments of this utility model, the insert block 320 is disposed on the upper half of the monitoring box 300, and two insert blocks 320 are provided and spaced apart from each other on the left and right. The insert block 320 is disposed on the upper half of the monitoring box 300 so that the cooperation between the insert block 320 and the locking slot 211 can limit the upper half of the monitoring box 300. The positioning protrusion 310 embedded in the positioning groove 111 mainly limits the bottom of the monitoring box 300, thereby achieving a more comprehensive limitation of the monitoring box 300. Compared with the traditional monitoring box 300, which is only fixed at the bottom with fasteners and has no limitation at the top, the embodiments of this utility model have more comprehensive limitation and improve installation stability.
[0046] Referring to Figure 3, in some embodiments of this utility model, the limiting block 330 is abutted against one side wall of the locking block 210, and the bottom of the limiting block 330 is lower than the bottom of the locking block 210. Thus, the limiting block 330 and the locking block 210 are abutted to achieve positioning, and the bottom of the limiting block 330 is lower than the bottom of the locking block 210. During installation, the limiting block 330 first abuts against the locking block 210 to achieve positioning, and then the insert block 320 can be aligned and inserted into the locking slot 211. This eliminates the need for repeated adjustments to align the insert block 320 with the locking slot 211 during installation, improving installation convenience.
[0047] Referring to Figures 3 and 4, in some embodiments of this utility model, a mounting block 220 is provided on the front side of the back plate 200. The mounting block 220 has a threaded hole 221, and the limiting member 400 is a screw threadedly connected to the threaded hole 221. The threaded connection enables the detachable connection of the limiting member 400. Moreover, with the threaded connection, during disassembly, it is only necessary to loosen the limiting member 400 so that the limiting member 400 disengages from the limiting hole 331, without completely disassembling the limiting member 400, which facilitates subsequent reinstallation. It is understandable that the limiting component 400, the mounting block 220, and the limiting block 330 can be symmetrically arranged in two sets on the left and right sides to achieve multi-position limiting and improve the stability of the limiting. Only two fasteners (limiting component 400) are needed for disassembly and assembly. Compared with the traditional monitoring box installation, which requires at least four fasteners to achieve stable installation with multi-position limiting, although this embodiment only uses two fasteners (limiting component 400) to install and fix the monitoring box, the bottom of the monitoring box has a positioning protrusion 310 that is embedded in the positioning groove 111 to achieve positioning and limiting, and the back also has an insert block 320 that can be aligned with the insertion slot 211 to achieve positioning and limiting. The positioning and limiting in this embodiment is sufficient and more comprehensive. Moreover, during installation, since the positioning protrusion 310 is embedded in the positioning groove 111 and the insert block 320 is inserted into the slot 211, the threaded hole 221 can be automatically aligned with the limiting hole 331, which makes it convenient for the limiting component 400 to be inserted into the limiting hole 331.
[0048] Referring to Figures 3 and 4, in a further embodiment of this utility model, the end of the screw is provided with a cylindrical portion 410 to insert into the limiting hole 331. Inserting the cylindrical portion 410 into the limiting hole 331 enhances the fit stability compared to embedding the threaded surface into the limiting hole 331. Of course, to reduce vibration transmission, as shown in Figure 4, a rubber sleeve 420 can also be fitted onto the cylindrical portion 410.
[0049] Referring to Figure 2, in a further embodiment of this utility model, the back plate 200 is provided with a second clearance hole 230. The second clearance hole 230 can not only reduce the weight of the back plate 200, but also reduce heat accumulation on the back of the monitoring box 300, and also facilitate wiring.
[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
