摘　　要：针对基坑(含浅基坑)轨道衡存在基坑内部积水、秤体大梁变形、设备维护维修不便等问题,研制一种无基坑超偏载数字指示轨道衡。介绍无基坑超偏载数字指示轨道衡的设计要求、结构和主要组成,并开展静态称重和超偏载测试。测试结果满足GB/T 15561—2008《静态电子轨道衡》、JJG 781—2019《数字指示轨道衡》和JJG(铁道)129—2004《铁道货车超偏载检测装置》等相关要求。In response to the problems of water accumulation inside the foundation pit(including shallow foundation pits),deformation of the weighing body beam,and inconvenient equipment maintenance and repair of the railweightbridge,the digital indicating railweightbridge without foundation pit developed.The paper introduces the design requirements,structure and main composition of the digital indicating railweightbridge without foundation pit with the function of detecling overload and unbalance load,and static weighing and unbalance load test are carried out.The test results meet the requirements of GB/T 15561—2008 Electronic static rail weighbridge,JJG 781—2019 Digital indicating railweighbridges,JJG(Railway)129—2004 Detecting device for overload and unbalance load of rail wagons and other related requirements.
