Abstract

The invention discloses a detection device for cracks in bridges, comprising a flat plate, a first flaw detection device, and a second flaw detection device. A control box is arranged on one side above the top of the flat panel. The second flaw detection device of the present invention detects cracks on the inside and outside of the side wall of the guardrail by changing different angles through the rotating lifting device, and adjusts the angle of the second flaw detection device through the angle adjustment device to detect cracks on the bottom of the bridge. The inner side and outer side of the wall and the bottom of the bridge are all tested by the second flaw detection device, which reduces the production and use costs and improves the scope of application of the device. The first flaw detection device can move in the length and width directions of the surface of the bridge to realize There is no dead angle detection on the surface of the bridge, which improves the working efficiency of the device.

Description

technical field

[0001] The invention belongs to the technical field of bridge detection, in particular to a detection device applied to bridge cracks. Background technique

[0002] A bridge is a building that is erected on rivers, lakes and seas so that vehicles and pedestrians can pass smoothly. Under the action of external factors, bridges often deform, leading to cracks or even damage. More than 90% of the damage of concrete bridges is caused by cracks. Engineering practice and theoretical analysis show that almost all concrete components work with cracks, and some cracks Small, even invisible to the naked eye (<0.05mm), generally there is no great harm to the normal use of the structure, and its existence is allowed, but some cracks are constantly generated and expanded under the action of load or external physical and chemical factors. Cracks above 0.20-0.30 mm will directly destroy the structural integrity of the bridge, cause concrete carbonization, peeling of the...
