[0023] Combination Figure 1-2 As shown, a bridge bearing detection device is used in the detection scenario of appearance defects of bridge bearings, including a telescopic rod 10, a detection host body 20, and a power supply 30; one end of the telescopic rod 10 is fixedly connected to the bottom of the power supply 30, and the detection host body 20 is fixedly arranged on a side of the power supply 30 away from the telescopic rod 10 and has a graphic analysis and processing system, and the detection host body 20 is electrically connected to the power supply 30; an external storage interface 211 is opened on one side of the detection host body 20, and the cross-sectional profile of the external storage interface 211 is consistent with the cross-sectional profile of the external storage unit.
[0024] The bridge bearing detection device provided in this application can be applied not only to the detection of appearance defects of bridge bearings, but also to other scenes that are inaccessible to humans (super-high, super-low, overhanging, etc.), and can be applied to the appearance defect detection of structures with potential safety hazards. Among them, the staff can stand on the ground, hold one end of the telescopic rod 10, and deliver the detection host body 20 fixed at the other end of the telescopic rod 10 to the station to be detected in the above scene, and then implement the detection, which optimizes the detection environment of the staff. The detection host body 20 in this application is connected to the mobile phone APP through a wireless signal, and the staff can wirelessly operate the detection host body 20 through the mobile phone, and the graphics analysis and processing system of the detection host body 20 itself can well process the data of appearance defects of the images collected for detection, and the difficulty of operation is significantly reduced. The power supply 30 used in this application is a conventional lithium battery, and the detection host body 20 is powered by a conventional lithium battery. When the power supply 30 is out of power, it can be charged or replaced, which effectively saves energy consumption.
[0025] It also includes a pan-tilt head 40, one end of which is fixedly connected to one side of the telescopic rod 10 close to the power supply 30, and the other end of the pan-tilt head 40 is fixedly connected to the bottom of the telescopic rod 10. The pan-tilt head 40 is movably connected to the power supply 30 relative to the telescopic rod 10.
[0026] The pan-tilt head 40 in the present application can adopt the pan-tilt head 40 in the prior art, and the rotation angle of the plumb plane is 60°, and the rotation angle of the horizontal plane is 360°. The pan-tilt head 40 in the present application fixedly connects the power supply 30 with the telescopic rod 10, in order to prevent the power supply 30 and the telescopic rod 10 from falling off during the inspection work of the staff, thereby causing a safety accident. On the other hand, through the setting of the pan-tilt head 40, the staff can adjust the angle of the power supply 30 in the horizontal plane, and then adjust the angle of the detection host body 20 located at the upper end of the power supply 30 in the horizontal plane, thereby realizing the multi-angle detection of the appearance of the bridge bearing by the detection host body 20, so as to improve the authenticity of the detection result.
[0027] The telescopic rod 10 includes a plurality of telescopic section rods 11 . The telescopic section rods 11 include a large diameter section and a small diameter section. The small diameter section of the telescopic section rod 11 is plug-fitted with the large diameter section of the adjacent telescopic section rod 11 .
[0028] The telescopic rod 10 in the present application is composed of a plurality of telescopic section rods 11, which can be extended to a height of 1-15M. The staff holds one end of the first telescopic section rod 11 and extends the remaining telescopic section rods 11 of the target height, and delivers the detection host body 20 to the detection station for detection. The small diameter section of the first telescopic section rod 11 is interference-fitted with the large diameter section of the adjacent telescopic section rod 11. This setting is to prevent the telescopic rod 10 from retracting when the staff holds the telescopic section rod 10 for detection, thereby avoiding interruption of normal detection operations.
[0029] The detection host body 20 includes a casing 21, a collection lens 22, and a fill light 23; the bottom of the casing 21 is fixedly connected to the side of the power supply 30 relative to the telescopic rod 10, the collection lens 22 is recessed in the front of the casing 21, and the fill light 23 is arranged beside the collection lens 22 and fixedly connected to the casing 21. The collection lens 22 and the fill light 23 are electrically connected to the graphic analysis and processing system attached to the detection host body 20 to perform image collection operations.
[0030] The acquisition lens 22 in this application uses a 4x optical zoom, which can perform 4k high-definition shooting to ensure the clarity of the image quality of the acquired image, and then ensure the validity of the data during subsequent image analysis and processing. The acquisition lens 22 is recessed in the front of the housing 21. On the one hand, when performing detection operations in a strong light environment, the edge of the housing 21 can be used to block part of the light to avoid the appearance of light spots in the image due to strong light; on the other hand, when performing detection operations in a rainy environment, the edge of the housing 21 can be used to guide water droplets to avoid unclear images due to water stains on the lens. The fill light 23 in this application is a professional-grade photography light with a color temperature of 5500K, and it is set next to the acquisition lens 22. The staff can send wireless signals through the mobile phone APP to control the detection subject to perform fill light operations to improve the quality of the acquired image.
[0031] The telescopic rod 10 is made of one or more of carbon fiber, aluminum alloy, and stainless steel. The purpose is to facilitate the staff to make multiple choices of the material of the telescopic rod 10, and to maximize economic savings by selecting the appropriate material to adapt to different working scenes. The telescopic rod 10 in the present application is made of carbon fiber, which is light, rigid, and easy to shrink, and can cope with most detection scenes.
[0032] In order to ensure that the telescopic section rod 11 is firmly connected to the adjacent telescopic section rod 11 when the operator holds the telescopic rod to deliver the detection host body 20 for detection, the inner side of the small diameter section of the telescopic section rod 11 is affixed with an anti-slip cover 12, the cross-sectional profile of the anti-slip cover 12 is trapezoidal, and the small diameter end of the anti-slip cover 12 is arranged on the side away from the small diameter section of the telescopic section rod 11. The provision of the anti-slip cover 12 can also ensure the stable progress of the detection operation. When the detection operation is completed, the operator only needs to pull the single telescopic section rod 11 back into the first telescopic section rod 11.
[0033] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.
[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the present invention.
