Method for inspecting tires, enabling the on-site detector of defects, the state of wear of the rubber, or the internal condition of the tire

摘要

The invention relates to a technical inspection method which comprises the specific application of an ultrasound wave perfectly adapted for interacting with the rubber and for detecting: defects, tears, gaps, the state of wear of the rubber, and the breakage of steel wires or meshes in giant OTR (off-the-road) tires. Said inspection consists of injecting, into any sector of the tire and using an ultrasound defect detector device, ultrasound waves that generate echoes by bouncing off breaks or interfaces in the material, the assessment of which yields a diagnosis of the internal condition and operating state of the tire.

主权项

1. Method for inspecting tires having an original thickness, which allows the detection of in situ defects, rubber degradation states, or tire internal condition, wherein said method comprises the following stages:
a. Calibrating an ultrasonic equipment with specific parameters; b. Determining a rubber remaining thickness of the tire and determining wear condition of the tire compared with the original thickness, wherein the tires are off the road tires comprising rims ranging from 22 to 70 inches; c. Using said ultrasonic equipment, manually running an ultrasonic scan over the tire wherein the running consists of perfectly conditioned high-energy ultrasonic waves entering into the tire rubber remaining thickness; and d. Receiving response echoes from reflections produced by the tire internal defects or discontinuities and collecting information about the internal condition through interpretation of the echoes.
