困難であった。``Conventional Techniques'' Conventionally, damage to steel cords buried inside belt conveyors, wire beams, etc., was not detected and caused cutting accidents. There is a device that detects metal fragments in ore carried out by a belt conveyor (Japanese Patent Laid-Open No. 53
-66787), it was difficult to predict belt breakage accidents.

て構成される。``Problems to be solved by the invention'' The purpose of the present invention is to prevent cutting accidents by detecting damage positions in long belt conveyors, wire ropes, etc. in advance. The present invention detects an inductance change signal at a joint or damaged part of a steel cord in an endless belt, wire rope, etc. and a reference position of the belt, rope, etc., and determines the damaged position of the steel cord. It is composed of a characteristic method for detecting damaged parts of steel cords on belt conveyors.

A driven roller 3 is provided at the other end, and the return belt 1 is provided with a tension roller 4, a tension weight 5, and a guide roller 6. The endless belt 1 has a belt reference position 7.
A reference position detection sensor 8 and a steel cord inductance detection sensor 9 are provided on the return belt side. An amplifier 10 is connected to the inductance detection sensor 9, and the amplifier 10 and the reference position detection sensor 8 are connected to the analysis bag jilt.
and connect it to the display unit 12. Connection may be made by wireless or wired signals. The analyzer 1) compares the detection signal from the amplifier 10 and the belt reference position mark 7 with a preset joint map based on the pattern of the detection signal from the detection sensor 8.
Determine whether the signal detected is at the joint or damaged location of the steel cord. In addition, it is preferable that the analysis device 1) is a device that can display the damaged location on the display unit 12 and issue an alarm when the same damaged location is detected once or several times in a row.
