摘要
根据《MT-T929-2004矿用高强度紧凑链》中有关规定,当链条累计输送量达到产品设计的输送量时,应至少进行一次破断负荷试验,链条的破断负荷不得小于公称破断负荷的90%。这样,许多待报废的链条就可以通过破断试验来判断是否完好,是否能够继续使用。为此,研制一种链条拉力试验的设备,用于检测链条。
According to the relevant provisions of the MT/T929 -2004 cumulative amount of the chain to achieve the delivery of product design, broken load shall not be less than 90% of the nominal breaking load. In be judged by breaking test to determine whether or not to continue to use. test equipment for testing the chain. mining high strength compact chain, when the should be at least a broken load test, the chain this way, many of the chain to be scrapped can To this end, the development of a chain tension test equipment for testing the chain.
