Technical Field
[0001] This utility model relates to the field of municipal bridge inspection technology, specifically to a bridge crack detection device that is easy to assemble. Background Technology
[0002] Bridges are generally structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. During use, bridges often develop cracks, which can seriously affect the safety of bridge use. Therefore, it is often necessary to inspect bridges for cracks during their use.
[0003] Currently, most existing bridge monitoring equipment uses video recorders to take pictures of the sides and bottom of the bridge from an upward angle, which facilitates subsequent comparison and detection. However, in actual operation, this method requires the use of trailers, support poles and other devices to lift the video recorder, and the stability of the video recorder must be ensured during lifting. Therefore, the installation process is very long and cumbersome, which can easily slow down the measurement efficiency and reduce the effectiveness of the device. Utility Model Content

[0020] Please see Figures 1 to 4 The present invention provides a technical solution: a bridge crack detection device that is easy to assemble, including a fixed base 1, a pedal 11 fixedly installed on the side end of the fixed base 1, a connecting box 2 slidably installed on the lower end of the fixed base 1, a first camera 23 installed on the side end of the connecting box 2, a connecting base plate 24 slidably installed on the lower end of the connecting box 2, a support arm 3 rotatably installed on the lower end of the connecting base plate 24, and a second camera 35 rotatably installed on the side end of the support arm 3.
[0021] In this embodiment, as Figure 1 and Figure 2 As shown, three first mounting frames 12 are fixedly installed at the lower end of the pedal 11. Each first mounting frame 12 has a first rolling wheel 13 rotatably installed inside. A support rod 14 is fixedly installed at the upper end of the fixed base 1. A fixed handle 15 is fixedly installed at the upper end of the support rod 14. This structure allows the first mounting frames 12 and the first rolling wheels 13 installed below the pedal 11 to facilitate subsequent sliding of the fixed base 1 with the fixed handle 15.
[0022] In this embodiment, as Figure 1 and Figure 3 As shown, extension plates 22 are slidably installed on both the upper and lower sides of the connecting box 2. A drive motor 21 is installed inside the connecting box 2. Each extension plate 22 is extended by cooperating with the connecting box 2 through the drive motor 21. This structure can extend the extension plates 22 to the upper and lower sides by cooperating with the drive motor 21 through the connecting box 2, thereby facilitating subsequent measurement of bridge bodies of different thicknesses.
[0023] In this embodiment, as Figure 1 and Figure 3 As shown, the connecting base plate 24 is slidably connected to the connecting box 2 via the extension plate 22. A second mounting frame 25 is fixedly installed at the upper end of the connecting base plate 24. A second rolling wheel 26 is rotatably installed inside the second mounting frame 25. This structure facilitates subsequent sliding of the device through the second mounting frame 25 and the second rolling wheel 26 installed above the connecting base plate 24.
[0024] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, two connecting rings 27 are fixedly installed at the lower end of the connecting base plate 24, and a rotating shaft 31 is rotatably installed at the side end of the support arm 3. This structure allows for quick connection between the connecting base plate 24 and the support arm 3 through the connecting rings 27 at the bottom of the connecting base plate 24 and the rotating shaft 31.
[0025] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, a first rotating motor 32 is rotatably mounted on the side end of the rotating shaft 31. The support arm 3 is rotatably mounted below the connecting base plate 24 through the rotating shaft 31, the first rotating motor 32 and the connecting ring 27. This structure can drive the rotating shaft 31 to rotate by starting the first rotating motor 32, and then cooperate with the connecting ring 27 to limit the position, thereby driving the support arm 3 to rotate below the connecting base plate 24.
[0026] In this embodiment, as Figure 1 and Figure 4 As shown, a limit frame 33 is rotatably mounted on the side end of the support arm 3, a second rotary motor 34 is rotatably mounted on the side end of the limit frame 33, and a second camera 35 is mounted on the lower end of the limit frame 33. This structure can adjust the camera angle of the second camera 35 by starting the second rotary motor 34 to drive the limit frame 33 to rotate along the support arm 3.
[0027] The method of use and advantages of this utility model: This easy-to-assemble bridge crack detection device operates as follows:
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when using the device, the user first places it on a horizontal surface. The user picks up the fixed base 1, installs a pedal 11 on the side of the fixed base 1, installs three first mounting frames 12 below the pedal 11, installs first rolling wheels 13 inside the three first mounting frames 12, installs a support rod 14 above the fixed base 1, and installs a fixed handle 15 above the support rod 14. Then, the user picks up the connecting box 2, installs a drive motor 21 inside the connecting box 2, installs extension plates 22 on the upper and lower sides of the connecting box 2, installs a first camera 23 on the side of the connecting box 2, and installs a connecting base plate 24 at the lower end of the extension plate 22 below the connecting box 2. Install the second mounting frame 25, install the second rolling wheel 26 inside the second mounting frame 25, and install two connecting rings 27 below the connecting base plate 24. Then, align the assembled connecting box 2 with the bottom of the fixed base 1 along the upper extension plate 22. Then, lift the support arm 3, install the rotating shaft 31 on the side of the support arm 3, install the first rotating motor 32 on the side of the rotating shaft 31, install the upper limit frame 33 on the side of the support arm 3 away from the rotating shaft 31, install the second rotating motor 34 on the side of the limit frame 33, and install the second camera 35 below the limit frame 33. Then, align the assembled support arm 3 with the rotating shaft 31 and the first rotating motor 34. 32 is installed in conjunction with the connecting ring 27. When the user needs to use the device, the user places the device on one side of the bridge to be measured, then steps on the pedal 11, extending the side connecting box 2 and other parts outside the bridge. Then, the user starts the drive motor 21, which, together with the connecting box 2, extends the extension plates 22 to the upper and lower sides until the upper part of the second rolling wheel 26 is lower than the bottom of the bridge. Then, the user pulls the fixed handle 15, positioning the three first rolling wheels 13 installed at the pedal 11 above the bridge surface and the second rolling wheel 26 below the bridge surface. At this time, the first rotating motor 32 and the second rotating motor 34 are started, and the first rotating motor 32 rotates in conjunction with the second rotating motor 34. The moving shaft 31 and connecting ring 27 drive the support arm 3 to rotate, which in turn drives the limit frame 33 to rotate along the support arm 3, thereby adjusting the camera angle of the second camera 35. When the appropriate illumination angle is adjusted, the user starts the first camera 23 and the second camera 35 to record. Then, the user pushes the fixed handle 15. With the cooperation of the fixed handle 15, the first mounting frame 12, the first rolling wheel 13, the second mounting frame 25, and the second rolling wheel 26, the device moves laterally. During the movement, the first camera 23 and the second camera 35 will record the bottom and sides of the bridge, which will be convenient for subsequent bridge crack detection.
