Description

Technical Field

[0001] This utility model relates to the technical field of road and bridge maintenance, specifically a bridge crack detection device. Background Technology

[0002] As a crucial component of transportation infrastructure, the structural safety of bridges directly impacts road safety and bridge lifespan. Over long periods of use, bridge structures are susceptible to damage such as cracks due to factors like loads, environmental conditions, and material aging. Failure to detect and address these issues promptly will severely compromise the bridge's load-bearing capacity and durability. Therefore, regular and precise inspection of bridge cracks is of paramount importance.

[0003] Currently, bridge crack detection mainly relies on manual visual inspection or the use of simple measuring tools such as calipers and crack width comparison cards, which suffers from low detection efficiency, strong subjectivity, and low data accuracy. In addition, some non-contact or electronic detection equipment, such as ultrasonic detectors and image recognition systems, although highly accurate, are complex, expensive, and require highly specialized personnel, making them difficult to deploy and use quickly in field or high-altitude working environments.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, see [reference] Figures 1-4 A bridge crack detection device includes a positioning frame 1, a scale 2, and a transducer 22.

[0023] The positioning frame 1 is fixedly connected to a dividing frame 3, and the two ends of the positioning frame 1 are fixedly connected to a connecting frame 5. The connecting frame 5 is provided with multiple sets of equidistant positioning holes 6. The two ends of the scale 2 are fixedly connected to a connecting seat 4, and the connecting seat 4 is fixedly connected to a connecting rod 7. The connecting rod 7 cooperates with the positioning holes 6.

[0024] The connecting frame 5 is equipped with an elastic support component for elastically supporting and fixing the positioning frame 1;

[0025] The transducer 22 is provided in two sets. The scale 2 is provided with a sliding groove 16. Two sets of positioning and mounting components are slidably installed in the sliding groove 16. The two sets of transducers 22 are respectively installed in the two sets of mounting components.

[0026] This utility model first adjusts the relative distance between the positioning frame 1 and the scale 2 according to the direction of the crack. During this process, the positioning hole 6 and the connecting rod 7 can cooperate to achieve stable installation between the positioning frame 1 and the scale 2, and at the same time adjust the relative distance between the positioning frame 1 and the scale 2.

[0027] Then, based on the direction of the crack, the relative position and distance between the two sets of installation components are adjusted by sliding. During this process, the relative position and distance between the two sets of transducers 22 are accurately measured using a scale ruler 2. Then, the device is pressed to compress the spring 11 support assembly, thereby moving the device closer to the road surface and allowing the transducers 22 to adhere to the road surface for crack detection. During the detection process, the positioning frame 1 and the dividing line frame 3 are used for precise observation of the crack, enabling rapid crack detection.

[0028] In one instance of this embodiment, please refer to Figures 1-4 The elastic support assembly includes a fixed frame 8 fixedly connected to the connecting frame 5, a fixed cylinder 9 fixedly connected to the fixed frame 8, a stop block 10 slidably connected inside the fixed cylinder 9, a connecting rod 12 fixedly connected to the stop block 10, a support block 13 fixedly connected to the connecting rod 12 passing through the fixed cylinder 9, a spring 11 installed inside the fixed cylinder 9 at the top of the stop block 10, a lifting frame 14 fixedly connected between the fixed cylinders 9, and a handle 15 fixedly connected to the lifting frame 14;

[0029] This invention uses the handle 15 and the lifting frame 14 to stabilize the operation of the device. When the device is in use, first, the support block 13 is oriented towards the ground and the device is placed in the crack. Then, the handle 15 is pressed, and the pressure is applied to the spring 11 through the connecting rod 12, thereby compressing the spring 11. At this time, the device is compressed and moves closer to the road surface, thus causing the transducer 22 to adhere to the road surface. After the test is completed, the handle 15 is released, and the spring 11 releases its elastic potential energy, thereby causing the transducer 22 to automatically rise away from the road surface.

[0030] In one instance of this embodiment, please refer to Figures 1-4 The positioning and mounting assembly includes a slider 17 slidably connected in the slide groove 16, an mounting cylinder 18 fixedly connected to the slider 17, a pointer 21 fixedly connected to the top of the mounting cylinder 18, the pointer 21 cooperating with the scale 2, the transducer 22 slidably connected to the mounting cylinder 18, and a limit block 23 fixedly connected to the top of the transducer 22, the limit block 23 cooperating with the mounting cylinder 18.

[0031] The positioning and installation assembly first inserts the transducer 22 into the installation cylinder 18. Then, the limiting block 23 cooperates with the installation cylinder 18 to limit the distance between the installation cylinder 18 and the transducer 22, thereby achieving stable installation of the transducer 22. After that, the position and relative distance of the two sets of transducers 22 can be adjusted by sliding the connection between the slide groove 16 and the slider 17. During this process, the position and relative distance of the two sets of transducers 22 are accurately measured by the cooperation between the pointer 21 and the scale 2.

[0032] In one instance of this embodiment, please refer to Figures 1-4 The mounting cylinder 18 is provided with a threaded hole 19, and a clamping bolt 20 is threadedly connected to the threaded hole 19. This utility model uses the cooperation between the clamping bolt 20 and the transducer 22 to push and clamp the transducer 22, thereby fixing the transducer 22 into the mounting cylinder 18.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
