Description

Technical Field

[0001] This utility model belongs to the field of crack monitoring technology, and more specifically, it relates to a real-time monitoring device for bridge cracks. Background Technology

[0002] Transverse cracks at the mid-span of the bridge bottom are a common bridge defect during bridge inspection. Cracks are usually discovered in the early stages of development during inspection. With increasing traffic volume and the rise of overweight vehicles, cracks develop rapidly. Manually monitoring cracks on every bridge 24 hours a day is impractical, and regular monitoring may miss the optimal treatment period, leading to bridge collapse and irreversible safety accidents and economic losses.

[0003] Application number CN202222610621.4 discloses a device for automatic alarm monitoring of cracks, specifically relating to the technical field of automatic alarm devices for crack monitoring. It includes a crack measuring device, a central processing unit, a high-definition camera, a display screen, a red light, a wireless SMS alarm, a green light, and a yellow light. The output terminals of the crack measuring device and the high-definition camera are both connected to the input terminal of the central processing unit. This invention, by setting the sensing distance between the photoelectric transmitter and receiver sensors, can convert the real-time measurement displacement of the crack width into an electrical signal. The video information transmitted from the high-definition camera to the display screen allows for immediate preliminary observation of the crack's condition, enabling timely intervention. Furthermore, it allows for real-time observation of the crack's condition, achieving dual monitoring and alarm functions: manual viewing of the crack via video and automatic alarm activation by the device. This results in better crack monitoring and alarm effects for bridges.

[0004] Based on the above patent searches and understanding of the application of existing bridge crack real-time monitoring equipment: When monitoring bridge cracks in real time, most of them install crack gauges at the outer end of the crack for monitoring. The fixed structure of traditional equipment is mostly fixed in design, making it difficult to flexibly adjust the fixed point position according to the structural characteristics around the cracks of different bridges. This makes it difficult to install on some special bridge structures, and it cannot be stably fixed, affecting the accuracy of monitoring.

[0005] When the detection rod of some monitoring equipment moves with the crack, stress bending is likely to occur, which makes the sliding between the detection rod and the monitoring body less smooth, thus affecting the accuracy of the monitoring data and making it impossible to reflect the actual changes of the crack in a timely and accurate manner. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a real-time bridge crack monitoring device. This addresses the issues of existing monitoring devices having fixed structures that are difficult to adjust the fixing point positions flexibly according to the structural characteristics surrounding different bridge cracks, leading to installation difficulties and unstable fixation on some special bridge structures, affecting monitoring accuracy. Furthermore, some monitoring devices' detection rods are prone to stress bending when moving with crack changes, resulting in insufficient smooth sliding between the detection rod and the monitoring body, thus affecting the accuracy of monitoring data and failing to reflect the actual changes in the cracks in a timely and accurate manner.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A bridge crack real-time monitoring device includes a dual-tube crack gauge; the dual-tube crack gauge has a sliding groove on each of its upper two sides, and the two upper sliding grooves of the dual-tube crack gauge are slidably connected to the lower two sides of a fork-shaped detection rod, a docking block is fixedly connected to the top middle position of the fork-shaped detection rod, a limiting frame B is fixedly installed on the left and right sides of the docking block, a screw B is rotatably connected to the middle position of each limiting frame B, an adjusting plate B is slidably connected to the inside of the limiting frame B, a threaded hole is opened in the middle position of the adjusting plate B, and the screw B is located in the threaded hole of the adjusting plate B.

[0009] According to one embodiment of the present invention, an L-shaped positioning plate B is fixedly installed on the outer side of each adjustment plate B, and a through hole is provided at the middle of the front end of each positioning plate B.

[0010] According to one embodiment of the present invention, a limiting frame A is fixedly installed on both sides of the lower position of the dual-tube crack gauge. The two limiting frames A are symmetrically distributed, and a screw A is rotatably connected to the middle position inside each limiting frame A.

[0011] According to one embodiment of the present invention, an adjusting plate A is slidably connected to the inner position of the limiting frame A, and a threaded hole is opened in the middle position of the adjusting plate A, and the screw A is located in the threaded hole of the adjusting plate A.

[0012] According to one embodiment of the present invention, an L-shaped positioning plate A is fixedly installed on the outer side of each of the adjustment plates A, and a through hole is provided at the middle of the front end of each positioning plate A.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting limit frame A and limit frame B, and with screw A and adjusting plate A and screw B and adjusting plate B respectively inside them, the horizontal position of positioning plate A and positioning plate B can be adjusted. This design can flexibly adjust the fixing point according to different structural environments around bridge cracks, so that the equipment can adapt to various bridge structures, ensure stable installation, and solve the problem of poor installation adaptability of traditional equipment.

[0015] 2. The design combines a dual-tube crack gauge with a fork-shaped detection rod. The dual-tube structure provides a stable guide for the sliding of the fork-shaped detection rod, effectively preventing stress bending when the detection rod moves with crack changes. This ensures the smooth sliding of the fork-shaped detection rod, enabling the dual-tube crack gauge to more accurately capture crack changes and improve the reliability of monitoring data.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a bridge crack real-time monitoring device, including a dual-tube crack gauge 1; the upper two sides of the dual-tube crack gauge 1 are respectively provided with a sliding groove, and the two upper sliding grooves of the dual-tube crack gauge 1 are respectively slidably connected to the lower two sides of the fork-shaped detection rod 101. A docking block 102 is fixedly connected to the top middle position of the fork-shaped detection rod 101. A limiting frame B3 is fixedly installed on the left and right sides of the docking block 102. A screw B301 is rotatably connected to the middle position of the interior of each limiting frame B3. An adjusting plate B302 is slidably connected to the interior position of the limiting frame B3. A threaded hole is opened in the middle position of the adjusting plate B302, and the screw B301 is located in the threaded hole of the adjusting plate B302.

[0028] Each adjustment plate B302 has an L-shaped positioning plate B303 fixedly installed on its outer side, and each positioning plate B303 has a through hole at the middle of its front end.

[0029] Among them, a limiting frame A2 is fixedly installed on both sides of the lower position of the double tube crack gauge 1. The two limiting frames A2 are symmetrically distributed, and a screw A201 is rotatably connected to the middle position inside each limiting frame A2.

[0030] The limiting frame A2 has an adjusting plate A202 slidably connected to its internal position. The adjusting plate A202 has a threaded hole in the middle position, and the screw A201 is located in the threaded hole of the adjusting plate A202.

[0031] Each adjustment plate A202 has an L-shaped positioning plate A203 fixedly installed on its outer side, and each positioning plate A203 has a through hole at the middle of its front end.

[0032] When using:

[0033] Place the dual-tube crack gauge 1 at a suitable monitoring position for bridge cracks, with the dual-tube crack gauge 1 and the fork-shaped detection rod 101 at their initial shrinkage values.

[0034] Rotating screw A201 causes the adjusting plate A202 to slide horizontally within the limiting frame A2, as the adjusting plate A202 is slidably connected to the limiting frame A2 and the screw A201 is located within the threaded hole of the adjusting plate A202. This rotation of the screw A201 causes the adjusting plate A202 to slide horizontally within the limiting frame A2. The sliding motion of the adjusting plate A202 moves the positioning plate A203, which is fixedly connected to it, until the rear end of the positioning plate A203 is in a suitable fixed position against the surface of the bridge structure. Using the through hole in the middle of the front end of the positioning plate A203, bolts are used to fix the positioning plate A203 to the bridge structure, completing the fixation of the equipment below.

[0035] Rotating screw B301 causes the adjusting plate B302 to slide horizontally within the limiting frame B3, as the adjusting plate B302 is slidably connected to the limiting frame B3 and the screw B301 is located within the threaded hole of the adjusting plate B302. The sliding of the adjusting plate B302 causes the positioning plate B303 to move, so that the rear end of the positioning plate B303 fits against the corresponding fixed position on the surface of the bridge structure. Using the through hole at the front end of the positioning plate B303, the positioning plate B303 is fixed to the bridge structure with bolts.

[0036] After the equipment is installed and fixed, the dual-tube crack gauge 1 begins to monitor bridge cracks in real time. When the crack changes, the fork-shaped detection rod 101 will slide accordingly in the groove of the dual-tube crack gauge 1. The dual-tube crack gauge 1 converts this change into a monitorable signal, thereby realizing the real-time monitoring function of bridge cracks. The dual-tube design of the dual-tube crack gauge 1 avoids stress bending of the fork-shaped detection rod 101 when sliding, further improving the smoothness of sliding monitoring between the fork-shaped detection rod 101 and the dual-tube crack gauge 1.

While this specification contains details of many specific implementations, these should not be construed as limiting the scope of the claims, but rather as descriptions of features specific to particular embodiments. The scope of this application is defined by the appended claims and their equivalents, and is not limited to the embodiments described above.
