Bridge cavity crack detector

Abstract

The invention relates to the technical field of bridge flaw detection, in particular to a bridge cavity crack detector, which can be folded, can automatically adjust the moving detection range of a flaw detection head according to bridges with different widths, and replaces the traditional operation mode by using a long-arm beam. The working flexibility of the device is improved; comprising a frame, a flaw detection head, a connecting plate, a telescopic moving assembly, a steering assembly and a folding assembly, the steering assembly is installed on the frame, the folding assembly is installed on the steering assembly, the flaw detection head is fixedly installed on the upper end face of the connecting plate, the connecting plate is installed on the telescopic moving assembly, and the telescopic moving assembly is installed on the folding assembly.

Description

technical field [0001] The invention relates to the technical field of bridge flaw detection, in particular to a bridge cavity crack detector. Background technique [0002] Bridges, as the hubs of roads, highways, railways and other transportation systems, need to be inspected and tested regularly to evaluate the damage status of bridges. Bridge cracks, as one of the most important bridge diseases, seriously affect the safety of bridges. If the bridge is used, the accident of bridge crash and death will occur more seriously. Therefore, it is very important to detect bridge cracks. At present, the main method for bridge detection is to use two sets of cantilever cranes on both sides of the bridge deck. The arm beam is hoisted, and the long-arm beam is under the bridge. One detection method is that the operator stands on the long-arm beam and moves to detect bridge cracks. Another method is to install the detection device through the lead screw slider mechanism. The detection...

[0002] As the hub of traffic systems such as roads, highways, and railways, bridges need to be regularly inspected and tested to evaluate the damage status of bridges. As one of the most important bridge diseases, bridge cracks seriously affect the safety of bridges. More serious accidents of bridge destruction will occur. Therefore, it is very important to detect bridge cracks. At present, the main way of bridge detection is to use two groups of cantilever cranes to inspect a group of long The arm beam is hoisted, and the long arm beam is under the bridge. One detection method is that the operator stands on the long arm beam and moves to detect bridge cracks. The other way is to install the detection device through the screw slider mechanism. The detection is carried out on the long-arm crossbeam, but such an operation method will make it difficult for the device to perform obstacle avoidance operations during the movement process, resulting in poor flexibility of the device, and different types of long-arm crossbeams need to be used according to bridges of different widths. The limitations of the use of the device are greatly improved
