Ⅱ型混凝土轨枕专用量具,属于非标量具,包括孔距测量器、孔斜测量器、厚度测量尺及坡度测量尺(含塞尺)。目前国内Ⅱ型枕专用量具为各厂自己加工制作,设计不合理,制造精度低,规格不统一。有些轨枕厂甚至没有专用量具,无法按TB2190对轨枕外形尺寸进行质量控制。该文详细介绍了Ⅱ型混凝土轨枕专用量具的设计原理、读数方法与尺寸传递。它解决了测量中关键性的定位问题,经试用和鉴定,该套专用量具具有操作简便,就位正确,测量准确的特点。它统一了各轨枕厂的测量尺度,使其检测的数据具有可比性,推动了轨枕检验标准化的工作,为正确评估轨枕产品质量提供了手段。
Type Ⅱ special measuring sleepers for concrete sleepers belong to non-standard measuring instruments, including hole gauge, hole skew gauge, thickness gauge and slope gauge (including feeler). At present, the special measuring tools for type Ⅱ pillow are manufactured by the factories themselves. The design is unreasonable, the manufacturing precision is low and the specifications are not uniform. Some sleeper factory does not even have special measuring tools, can not according to TB2190 sleeper dimensions quality control. This paper introduces in detail the design principle, reading method and size transfer of type Ⅱ concrete sleepers. It solves the key positioning problems in the measurement, the trial and identification, the set of special measuring tools with easy operation, the right place, the measurement accuracy. It unifies the sleeper factory measurement standards, to make it comparable to the test data, promote the standardization of sleeper inspection work, to correctly assess the sleeper product quality provides a means.
