无基坑静态轨道衡在贸易计量中的应用——论本钢老专用线有基坑轨道衡改造成无基坑轨道衡

Application of non excavation static rail weighbridge in the trade measurement——On the old sidings with foundation pit of Benxi Iron and Steel rail weighbridge transformed into non excavation track scale

本钢板材股份有限公司(以下简称"本钢")老专用线原先安装一台贸易用的有基坑静态轨道衡。使用的时间不长,但已经出现刚性台面变形等机械方面的问题。计量准确度不稳定,维护周期逐渐频繁,维护工作量在增加,半年检定压力增大。因此,本钢决定对该轨道衡进行无基坑改造,来保证轨道衡的稳定性,减少维护工作量。改造中,还增加了动态计量的功能,动态计量性能达到《JJG 234-2012自动轨道衡》的1级。

Benxi Iron and Steel had to install a pit static rail weighhridge with old siding~ which has problems such as the mechanical aspects of the rigid surface deformation within a short time, such as instable measurement accuracy, the increasingly frequent maintenance cycle, maintenance workload increases, and pressure increases first half of verification. Therefore, Benxi Iron and Steel company decided to increases the dynamic measuring function, dynamic measurement of performance to the JJG 234-2012 automatic weighbridge level 1 to ensure the stability of track scale and reduce maintenance workload.
