Problems solved by technology
The work intensity and danger of bridge inspectors going under the bridge to check are very high
[0012] 2. Restricted by the bridge structure (such as a high bridge) and the bridge's environment (such as a water bridge), bridge inspectors cannot fully complete the inspection under the bridge with tools such as ladders, boats, and high-power telescopes, making these bridges exist for a long time. Missed inspections increase the safety hazards of bridges
Since the location information of the shooting site cannot be added to the photo, the bridge inspection personnel can only record the name of the photo on the spot, and after returning to the base, use other means to merge the certificate photo with the bridge inspection record
Increased workload and chance of error for bridge inspectors
[0014] 4. Since the high-power telescope does not have the shooting function, it is difficult to take a photo of the certificate when using a high-power telescope for visual inspection
Bridge inspectors can only describe the found diseases in written form
[0015] 5. The forms frequently inspected by bridges are paper forms filled in by hand, which is not conducive to reading, saving and querying

Embodiment Construction
[0046] The inspection system used in the present invention is mainly composed of three parts: a stand, a video component and an operation terminal.
[0047] Such as figure 1 , figure 2 As shown, the platform is mainly composed of a multi-section telescopic sleeve rod 1, a hook arm 2, a fixed fixture 3, a movable fixture I4, a movable fixture II5, a telescopic wire rope 6, a wire rope hoist 7, a motor 8, a transmission gear 9, Several parts such as guide pulley 10 form. In order to reduce the weight, the stand is made of aluminum alloy and plastic parts, and the weight of the whole stand is less than 11 kg.
[0048] Such as figure 1 , image 3 As shown, the hooking arm 2 and the fixing jig 3 are foldable for storage, and the hooking arm 2 and the fixing jig 3 are in the storage state when the stand is moved and stored, which can effectively reduce the volume when carried. Before use, the hook arm 2 and the fixing fixture 3 need to be launched, and the fixing fixture 3 is ...

The method has the advantages of meticulous and comprehensiveness, high automation degree, light weight and quickness andhigher scientific degree and systematization.
Description
technical field [0001] The invention relates to an inspection method, in particular to a method for video inspection of a bridge structure by using a video inspection system, and belongs to the technical field of bridge structure inspection. Background technique [0002] According to the "Technical Specifications for Urban Bridge Maintenance (CJJ99-2003)" promulgated and implemented by the Ministry of Construction of the People's Republic of China on March 1, 2004 and the "Code for Maintenance of Highway Bridges and Culverts (JTG H11-2004)" promulgated and implemented on June 28, 2004 Provisions. Bridge inspections are divided into regular inspections, regular inspections and special inspections. [0003] 3.2.1 of "Code for Maintenance of Highway Bridges and Culverts (JTG H11-2004)" stipulates that the cycle of frequent inspection depends on the technical condition of the bridge, generally not less than once a month, and irregular inspections should be strengthened during t...
