DEVICE AND A METHOD FOR INSPECTING LINER ABRASION, CAPABLE OF EASILY MOVING AND INSTALLING

摘要

PURPOSE: A device and method for inspecting liner abrasion are provided to multiply the accuracy of an liner abrasion inspection because liner abrasion is calculated by measuring a distance between two liners facing to each other by receiving/transmitting laser.;CONSTITUTION: A device(400) for inspecting liner abrasion comprises a liner abrasion calculation unit(410) and a magnetic holder(420). The liner abrasion calculation unit measures a distance two liners facing to each other through laser receiving/transmitting operation and calculates liner abrasion based on a measurement result. The magnetic holder attaches or separates the liner abrasion calculation unit to one liner between the two liners facing to each other. The liner abrasion calculation unit comprises a laser sensor and signal processing unit. The laser sensor counts a time that laser is reflected and returned after the laser sensor irradiates the laser, thereby measuring the distance between the two liners. The signal processing unit converts the distance between the two liners measured by the laser sensor into the liner abrasion.;COPYRIGHT KIPO 2012
