Abstract
A tire inspection device includes a gas sensor disposed outside of a tire and facing an outer surface of the tire. The gas sensor detects a gas that fills the tire.
Claims13
A gas leak inspection device comprising:
- a gas sensor disposed outside of a hollow inspection target and facing an outer surface of the hollow inspection target;
- and
- an actuator that produces relative movement between the hollow inspection target and the gas sensor while the gas sensor faces the outer surface of the hollow inspection target,
- wherein the gas sensor detects a gas that escapes the hollow inspection target,
- wherein the actuator produces relative movement between the hollow inspection target and the gas sensor by rotating the hollow inspection target about an axis of the hollow inspection target, and
- wherein the gas sensor comprises a plurality of gas sensors spaced apart in a circumferential direction of the hollow inspection target and centered about the axis of the hollow inspection target.
A gas leak inspection system comprising:
- a gas leak inspection device comprising:
- a gas sensor disposed outside of a hollow inspection target and facing an outer surface of the hollow inspection target, wherein the gas sensor detects a gas that escapes the hollow inspection target;
- and
- an actuator that produces relative movement between the hollow inspection target and the gas sensor while the gas sensor faces the outer surface of the hollow inspection target;
- and
- an additional gas leak inspection device including an additional gas sensor and that covers a partial area of the outer surface of the hollow inspection target and inspects the partial area for presence of a gas leak.
A gas leak inspection method using a gas leak inspection device including a gas sensor configured to be disposed outside of a hollow inspection target, to face an outer surface of the hollow inspection target, and to detect a gas escaping the hollow inspection target and an additional gas leak inspection device including an additional gas sensor and being configured to cover a partial area of the outer surface of the hollow inspection target and to inspect the partial area for presence of a gas leak, the method comprising:
- inspecting the hollow inspection target for a gas leak using the gas leak inspection device;
- and
- inspecting the partial area for presence of the gas leak using the additional gas leak inspection device after the hollow inspection target is inspected for the gas leak using the gas leak inspection device.
A gas leak inspection device comprising:
- a gas sensor disposed outside of a hollow inspection target and facing an outer surface of the hollow inspection target;
- a housing unit that houses the hollow inspection target;
- and
- a stirrer that stirs air inside the housing unit,
- wherein the gas sensor is disposed in the housing unit and detects a gas that has leaked out from inside the hollow inspection target housed in the housing unit, and
- wherein the stirrer includes a fan disposed inside the housing unit.
A gas leak inspection method comprising:
- disposing a hollow inspection target inside a housing unit;
- introducing a gas into the hollow inspection target;
- and
- detecting the gas that escapes the hollow inspection target, in an atmosphere outside the hollow inspection target,
- wherein the gas comprises a reactive gas that reacts with a gas sensor disposed outside of the hollow inspection target, the gas sensor being disposed in the housing unit, and
- wherein detecting the gas comprises detecting the reactive gas with the gas sensor, in the atmosphere outside the hollow inspection target.
