为了准确掌握线路的轨距水平状态,考核线路质量,指导工区消灭超限处所,确保行车安全;为了提高检查作业的准确性,减轻劳动强度,提高工作效率,我们研制了GJ—1型轨距水平检查小车,如图1。已于1983年1月经局鉴定通过。鉴定认为,小车技术较为先 In order to accurately grasp the level of track gauge level, assess the quality of the line, guiding the work area to eliminate overrun spaces, to ensure traffic safety; In order to improve the accuracy of inspection operations, reduce labor intensity and improve work efficiency, we developed the GJ-1 gauge Check the car level, shown in Figure 1. In January 1983 by the Bureau identified. Identification that the car technology is more first
