Description

Technical field: [0001] The invention relates to a device for detecting the size of an infrared bridge concrete component, which belongs to the technical field of bridge detection equipment. Background technique: [0002] The application field of this technology is mainly aimed at the following three types of bridges: 1. Bridges under construction; 2. Bridges that are about to be opened to traffic and need to be inspected; 3. Bridges that need to be inspected after they are opened to traffic. According to the relevant regulations of the Ministry of Transport, the size of the concrete members must be inspected to ensure the safe operation of the bridge during its opening to traffic. At present, the commonly used method for measuring the size of bridge concrete components is the conventional method in which inspectors use steel tapes to directly measure the size of bridge concrete components. However, there are still three problems in the above method in the actual detection ...

AI Technical Summary

Problems solved by technology

However, there are still three problems in the above method in the actual detection work: 1. The detection error is large. When detecting the size of the bridge concrete member, a steel ruler is used for detection, but the steel ruler often appears in the actual construction site. The situation of sagging, twisting, and deformation , the detection is affected by factors such as external wind, dangerous terrain, and personnel operation, so the detection error is relatively large; 2. The work efficiency is low. When using a steel ruler to detect concrete components, because the detection personnel need to reach the vicinity of the component to detect, However, in actual work, inspectors need to use bridge inspection vehicles or climb steep cliffs to reach the vicinity of the components, so the direct measurement method of steel rulers is inefficient in detecting the size of concrete components of bridges; When measuring the size of concrete components of bridges, inspectors need to use bridge inspection vehicles or climb cliffs and steep slopes to reach the vicinity of the components. When climbing cliffs and steep slopes, inspectors face huge safety hazards, such as falls, rockfall injuries, steep slopes, and other dangerous situations It often happens, and sometimes the inspectors even pay the price of their lives, so the direct measurement method of steel rulers to detect the size of bridge concrete components has a great potential safety hazard

[0003] In order to overcome the shortcomings of existing bridge concrete component size detection devices, such as large detection errors, low work efficiency, and large safety hazards, the present invention is provided
