输送带接头运行寿命试验装置的研制及应用

摘要

输送带在使用过程中，易发生因接头疲劳而断开的安全事故。为此，研制了输送带接头运行寿命试验装置。该装置采用滑台作为试验台基座，电动机与减速器作为驱动系统，液压系统控制输送带的张力，光电传感器测量周转数，工控机与可编程控制器实施集散式控制。通过试验验证，该装置运行可靠，满足试验要求。%The conveyor belt is easy to fracture due to its splicer fatigue in use. For this purpose, an operating life test device for conveyor splicer was developed. This device adopts a sliding table as the test base, an electric motor and reducer as driving system, apply a hydraulic system for the tension control of the conveyor belt, a photoelectric sensor for the revolution measurement, an industrial PC and programmable controller for the implementation of centralized - distributed control. Experimental verification showed that this test system is reliable in operation and can meet the test requirements.
