Description

Technical Field

[0001] This utility model relates to the field of bridge inspection technology, specifically a novel device for monitoring cracks in the exterior facade of bridges. Background Technology

[0002] As transportation routes expand to be wider and longer, bridges need to be built in many places due to limitations such as terrain. These bridges require regular monitoring and maintenance to ensure traffic safety. Currently, many bridge inspections rely on human observation to check for damage, cracks, or weld defects. This method is subjective and depends on the observer's experience. Furthermore, it is difficult to detect potential safety hazards in bridges under insufficient lighting conditions.

[0003] For example, application number CN202121022250.7 and publication number CN215894414U, "A Bridge Crack Monitoring Device", by setting up connecting components including a U-shaped connecting rod, a vertical hydraulic cylinder and a horizontal hydraulic cylinder, can realize the monitoring device occupying the space on the pedestrian bridge to monitor the area under the bridge.

[0004] The aforementioned patent still has some problems. The device can only monitor the area under the bridge and cannot monitor the sides of the bridge. Cracks can also appear on the outer side of the bridge, posing a safety hazard.

[0005] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the dimensions of the components in the drawings are not actual dimensions.

[0025] This utility model embodiment provides a novel device for monitoring cracks in the exterior facade of bridges, such as... Figure 1-3 As shown, it includes a moving component 1, a connecting component 2, and a monitoring component 3. The moving component 1 and the monitoring component 3 are connected by the connecting component 2. The moving component 1 is equipped with a cylinder 11, and the output end extends out of the top of the moving component 1. The extension and retraction of the output end of the cylinder 11 can drive the connecting component 2 and the monitoring component 3 to move up and down to adjust the position of the camera 34.

[0026] Reference Appendix Figure 1-3The connecting assembly 2 includes a connecting plate 21, a connecting arm 22, a first hydraulic cylinder 23, and a second hydraulic cylinder 24. One end of the connecting plate 21 is fixed to the output end of the cylinder 11, and the other end extends laterally beyond the moving assembly 1. The cylinder body of the first hydraulic cylinder 23 is hinged to the upper end of the connecting plate 21. The output shaft of the first hydraulic cylinder 23 is hinged to one end of the connecting arm 22. The end of the connecting plate 21 away from the moving assembly 1 is hinged to the middle of the connecting arm 22 near the output shaft of the first hydraulic cylinder 23. The end of the connecting arm 22 away from the first hydraulic cylinder 23 is hinged to the monitoring assembly 3. The lower end of the monitoring assembly 3 is provided with an extension arm 31. The extension arm 31 extends laterally beyond the monitoring assembly 3 in the direction away from the moving assembly. The cylinder body of the second hydraulic cylinder 24 is hinged to the middle position of the connecting arm 22. The output shaft of the second hydraulic cylinder 24 is hinged to the end of the extension arm 31 away from the monitoring assembly 3.

[0027] With attachment Figure 2 Taking a perspective example, when the output shaft of hydraulic cylinder 23 retracts, it drives the connecting arm 22 to rotate counterclockwise; when it extends, it rotates clockwise. When the output shaft of hydraulic cylinder 24 retracts, it drives the extension arm 31 and the monitoring component 3 to rotate counterclockwise; when it extends, it rotates clockwise. Through the cooperation of hydraulic cylinders 23 and 24, the horizontal and vertical states of the monitoring component 3 are fixed, thereby enabling the monitoring of cracks at the bottom and outer surface of the bridge body.

[0028] The side wall of the moving component 1 is provided with a counterweight frame 12, into which counterweights can be added to increase the stability of the overall device.

[0029] The hinges between hydraulic cylinder 23 and connecting plate 21 and connecting arm 22, the hinges between hydraulic cylinder 24 and connecting arm 22 and extension arm 31, and the hinges between connecting plate 21 and connecting arm 22 are all completed through auxiliary connector 4.

[0030] The monitoring component 3 includes a plate 32, one end of which is provided with a connecting groove 33. The end of the connecting arm 22 away from the hydraulic cylinder 23 extends into the connecting groove 33 and is hinged to the plate 32. When the monitoring component 3 is subjected to the extension and retraction of the hydraulic cylinder 24, it rotates with the connecting arm 22 through the connecting groove 33.

[0031] The plate 32 is equipped with a camera 34 and a ring light 35. The camera 34 is located in the center of the ring light 35. The top of the plate 32 away from the connecting groove 33 is equipped with a barrier 36. The barrier 36 on the plate 32 of the monitoring component 3 can prevent the camera 34 from getting too close to the bridge body and being damaged when the device is working. The ring light 35 makes the illumination more uniform, thereby obtaining a more accurate monitoring effect.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
