检衡车及测速装置在动态汽车衡检定中的应用研究

Study on applying value-check car and speed-measuring device to verify instruments for weighing road vehicles in motion

介绍了车载液压起重尾板式专用检衡车的结构设计(包括车辆底盘、货箱改装和检定专用随车叉车等)、工作原理和操作使用方法,并比较说明同传统液压吊臂式检衡车相比较在开展动态汽车衡检定工作时的优越性,论述了便携式车辆测速装置在动态汽车衡动态称量参数检定中的具体应用。综合应用这两项新技术的专用检衡车设计合理、功能齐全、性能稳定,各项指标均满足JJG 907-2006对开展动态汽车衡计量检定的技术要求。

This paper introduced the structure design, working principle and operation method of the special value-check car of hydraulic lifting tailboard type （including the vehicle chassis, container conversion and special forklift for verification）. Compared with the traditional hydraulic arm type of value-check car, it is superior in verification of instruments for weighing road vehicles in motion. And the authors discussed the specific application of the portable vehicle speed-measuring device in dynamic verification. The special value-check car that used two new technologies was reasonable designed. It is muhifunctional and stable in performance, and all the parameters are accord with the related technical requirements of JJG 907-2006.
