Abstract
A device and method for measuring the elongation, or stretch, of a conveyor belt. The device comprises a base, a measurement starting mark on the base and an elongation scale on the base spaced from the measurement starting mark and indicative of a percentage of belt elongation for a first belt pitch. A first repeating, measurable feature of the conveyor belt is aligned with the measurement starting mark and the position of a second repeating, measurable feature of the conveyor belt relative to the elongation scale is measured to determine a percentage of elongation.
Claims19
A device for measuring elongation of a conveyor belt, comprising:
- a base;
- a measurement starting mark on the base;
- and
- an elongation scale spaced from the measurement starting mark, the elongation scale comprising a sequence of marks on the base, each mark corresponding to a percentage of belt elongation for a first belt pitch.
A device for measuring elongation of a conveyor belt, comprising:
- a base;
- a measurement starting mark on the base;
- a first elongation measurement region spaced from the measurement starting mark by a first distance, the first elongation measurement region corresponding to a first belt pitch, wherein the first distance is a multiple of the first belt pitch;
- and
- a second elongation measurement region spaced from the measurement starting mark by a second distance, the second elongation measurement region corresponding to a second belt pitch, wherein the second distance is a multiple of the second belt pitch.
A method of measuring conveyor belt elongation in a conveyor belt comprising a plurality of connected conveyor belt modules, comprising the steps of:
- aligning a first structural feature of a first conveyor belt module with a measurement starting mark on a base of a measuring device;
- aligning a second conveyor belt module with an elongation scale on the base of the measuring device;
- and
- determining a position of a first structural feature of the second conveyor belt module along the elongation scale on the measuring device.
