Abstract

In the Belt Conveying Laboratory (LTT) at the Faculty of Geoengineering, Mining and Geology at Wroclaw University of Technology a new area of application has been found for the newly developed high resolution magnetic diagnostic device for assessment of steel cord conveyor belts condition. In addition to monitoring of belts during their operation on conveyors this device can be used in LTT as the new tool in belts resistance to puncture investigations. High resolution images of changes in magnetic field of magnetized cord wires can be used for evaluation of failures and cuts caused by dynamic impact of iron head (striker) during laboratory tests without belt cover removal. The usefulness of the device is even greater due to not only condition of steel cord belts can be evaluated, what for this device was developed, but it allows also on observations of failures in impact-resistant metal breakers in textile belts. Breakers are frequently made of thin wires vulcanized above carcass inside the top cover laterally to the center line of the belt. The aim of breakers is protection of the expensive core against failures caused by big lumps of rock with sharp edges falling onto belt surface in loading points. Their role is shock absorption to minimize gouging and resistance of longitudinal rips. Due to breaker wires can also be magnetized after changing the direction of samples of punctured belts they can be monitored using the developed device at the testing conveyor. In the paper the first outcomes of application of magnetic diagnostic device for evaluation of punctured steel cord belts and textile belts with metal breakers are presented.

一种研究皮带抗穿刺性能的新工具

在弗罗茨瓦夫工业大学地球工程、采矿和地质学院的带式输送实验室(LTT)，新开发的用于评估钢丝绳输送带状况的高分辨率磁性诊断装置已经找到了一个新的应用领域。除了监测输送带在输送机上的运行情况外，该装置还可作为LTT中输送带抗穿刺性调查的新工具。在不拆除带盖的情况下，利用高分辨率的磁化帘子线磁场变化图像，对实验室试验中铁头(打头)动态冲击造成的故障和割伤进行评估。该设备的实用性甚至更大，因为不仅可以评估钢帘线带的状况，为该设备开发的内容，而且还可以观察纺织品带中抗冲击金属断路器的故障。破碎机通常由薄钢丝制成，硫化在上盖内的胴体上方，横向与皮带中心线相连。破碎机的目的是保护昂贵的岩心，防止在装载点上大块锋利的岩石落在带表面造成破坏。它们的作用是减震，以尽量减少纵撕裂的凿削和阻力。由于断路器导线也可以在改变穿孔带样品的方向后磁化，因此可以使用开发的设备在测试输送机上对其进行监测。本文介绍了磁性诊断装置在钢丝帘子带和带金属断路器的纺织带穿孔检测中的初步应用结果。
