Abstract

Methods and devices for measuring elongation, wear, and internal temperature of a conveyor belt to catch signs of conveyor belt failure such as breakage by detecting a magnetic field from a magnetic body by using a magnesium sensor, as well as a rubber magnet sheet as a magnetic body and a method of producing the sheet, the rubber magnet sheet being able to be used while it is embedded in the conveyor belt. To measure elongation of a running conveyor belt ( 11 ), a magnetic field of a magnetic body ( 2 ) embedded in the belt ( 11 ) is detected by a magnetism sensor ( 3 ) fixed to the earth, and elongation of the belt ( 11 ) is calculated from temporal variation of the detected magnetic field.

Description

technical field [0001] The present invention relates to a method and a device for measuring the elongation of a conveyor belt, a method and a device for measuring the amount of wear of a conveyor belt, a method and a device for measuring the temperature of a conveyor belt, a rubber magnetic plate and a A method of manufacturing a rubber magnetic plate. Background technique [0002] Large conveyor belts are often used where they are out of sequence and therefore inaccessible, such as natural resource extraction sites, so that maintenance and inspection of the conveyor belt cannot be adequately realized. In such a case, the elongation, wear, or temperature of a part of the conveyor belt sometimes increases abnormally, causing the conveyor belt to suddenly break, so that the work has to be stopped. In this case, more time and expense are required for repair. Therefore, it is highly desirable to have a method for detecting unexpected symptoms in advance for preventive maintena...
