Portable bridge structure appearance inspection apparatus

Abstract

The invention discloses a portable bridge structure appearance inspection apparatus, which comprises a WIFI camera, a camera fixation cover, a lighting device, an adapter bracket assembly, a first control rod, a second control rod and a receiving device, wherein the WIFI camera and the lighting device are arranged on the camera fixation cover, the camera fixation cover is fixedly connected on thefirst control rod through the adapter bracket assembly, the end portion of the second control rod is provided with a bush, the bush is connected on the first control rod in a sleeved manner, and the WIFI camera is connected to the receiving device through a WIFI signal. The portable bridge structure appearance inspection apparatus of the present invention has characteristics of simple structure, easy carrying, no influence on traffic, substantially saved manpower cost, substantially saved material resources and substantially saved equipment cost, and can complete the bridge inspection work bytwo people.

Description

technical field [0001] The invention belongs to the technical field of structure inspection, and in particular relates to a portable bridge structure appearance inspection device. Background technique [0002] At present, there are more than 700,000 bridges in the country. In the past 30 years, the number of bridges built in China is two or three times more than any other country in the world. The "Code for Maintenance of Highway Bridges and Culverts" stipulates that periodic inspections of highway bridges and culverts should be carried out. Bridge inspections are divided into regular inspections, regular inspections and special inspections. At the same time, my country's bridges are facing the same problem as bridges in many countries in the world, that is, a large number of bridges have entered the "aging" stage, and many of them have already suffered from various "diseases", but they have been operating with "diseases" all year round, lurking presents a huge security risk...

AI Technical Summary

Problems solved by technology

[0005] Second, use the telescope method: the jitter has a great influence during the inspection, it is easy to lose the target from the field of vision, and it is impossible to take pictures of the diseased target for evidence collection

[0006] Third, set up the bracket: it can only be used in the case of low headroom, and the inspection cost is high and the efficiency is extremely low. It is only used in special inspection cases

[0007] Fourth, portable bridge structure appearance inspection equipment: when encountering a bridge whose superstructure is a beam-lattice system, such as a T-girder bridge or a small box-girder bridge, the inspection blind spot is very large, which is basically not practical, and the equipment structure is complex, and it is difficult for each equipment High requirements for components to work together and poor stability

[0008] Fifth, height-climbing equipment: There are high requirements for the ground under the bridge. Generally, it is required that the operating vehicle equipment can be driven under the bridge span to be inspected, and the application range is small.

[0009] Sixth, unmanned aircraft: the problem of satellite signal loss under the bridge cannot be solved, and the problems of stability and anti-collision also need to be solved urgently.

But the shortcomings are also obvious. Bridge inspection vehicles have a greater impact on traffic, especially bridges with few lanes; the cost of use is high, and the manpower and material resources required for traffic maintenance are relatively large; there are trees and wires under the bridge. For bridge spans in other situations, basically we can only give up the inspection. For bridge spans with sign boards and lampposts on bridge guardrails, etc., the workload of retracting and retracting is heavy and the efficiency is low.
