称量液、固态载货车的动态轨道衡

Dynamic Weighbridge for both Waggons Loaded with Solid or Liquid

本文介绍一种既能称量载有固态货物的货车又能称量装有液体货物的罐式货车的动态轨道衡,它根据固态货车和罐车车体的尺寸特征,自动切换称量方式:对罐车采用整车计量;对固态货车则采用双转向架计量。不仅成功地克服了罐车内液体晃动对称量精度的影响,且确保了尺寸繁多的各种固态货物车的正常称量。运行状况良好。

In this paper, a kind of dynamic weighbridge is introduced, by which both the waggons loaded with solid and ones with liquid can be weighed. The measuring mode of the weighbridge can automatically change according to the difference between the bodies of solid-waggons and liquid-waggons. The former are measured in two times, half by half, and the later are weighed as a whole. By this way, the accuracy of the measurement is not effected by the sloshing of the liquid in the moving waggons, on the other hand, all kinds of waggons for all kinds of solid cargo can also be accurately weighed. One of this kind of weighbridge has worked in good state since March, 1992 at Shacheng Railway Station, Beijing Railway Bureau. The economic benefit is over 1. 2 million Yuans each year. In March, 1992 and November, 1992, it passed the examine and determine by the State Weighbridge Examine Center. Its measuring accuracy is in ±0. 2% and the permited passing speed for solid-waggons is 3-12 km/h and for liquid-waggons is 3-10 km/h.
