在矿山发展的新形势下,对安全系数和生产效率的要求越来越高。矿山的高效、安全生产是发展的基础保障。然而,随着设备使用年限的增加,设备故障也会逐年攀升,对设备可开动率造成了很大的影响。因此,如何科学合理地管理并维护好运输设备、提高设备可开动率就显得尤为重要。为此,开展"多维一体"设备管理模式[1],提高设备可开动率就显得尤为重要。 相似文献

The key of articulated truck is to connect the front and rear parts of the hinged joint, which connects the power part of the vehicle with the load part. As the connector of the front frame and the rear frame, the hinged joint plays an important role in the hinged joint. After a long time running, the hinge joint is affected by the impact, bending moment and other composite loads, and its thread will appear wear, break and other failure forms. Based on the analysis of the structure and current situation of the hinge joint, the advantages and disadvantages of the hardfacing process and the inlay process are compared, and a better scheme for repairing the thread wear of the hinge joint is proposed. 相似文献
