随着社会的发展，火车、高铁、汽车、飞机等交通工具也都使得人们的出行更加便利。80%的人会选择火车或者高铁火车这种经济安全的交通方式。作为许多人会选择的一种出行方式，那么它的运行安全就需要特别重视。众所周知，火车是在轨道上运行的，那轨道就特别重要，铁道线上两条钢轨的好坏，直接关系到火车的安全。所以钢轨是火车安全运行的核心。在铁路车辆运行过程中，钢轨不断受到摩擦，积压，冲击，疲劳等作用会产生内部损伤，钢轨内部损伤会引起许多断轨事故，及时发现轨道疲劳损伤、微小裂痕等隐患是铁路安全运行的重要保障。这个时候素有铁路医生的轨道探伤车就出现在人们的视野。

Rail doctor-Automatic rail detection trolley & Rail flaw detection trolley

With the fast development of our society, railway, high-speed railway, motors and jets make our travel become more and more convenient. Over 80% of us travel by train or high-speed railway because they are safe and cost saving vehicles. As a vehicle which is chosen by most of us, we past pay more attention to its safety. Its well known to us all that they run on the rail so the quality of the rail is very important for the safety of the vehicle. So the rail is the core factor to make sure the safety of vehicle running. In the process of running, the inner hurt derives from fabric, heavy load, pressure may cause accidents. So if have found the hurt and tinny scar of the rail in advance, we would keep away from many accidents. At this time, the so-called rail flaw detection vehicle appear.

帕菲特企业2015年着手研究制造出了轨道探伤车，主要包括驱动系统、伺服系统、探伤系统和电气控制系统等四个子系统。具有检测效率高、检测准确率高、现场实时探伤、组装方便，续航能力强等特点。

Perfect have searched and manufacture the rail detection trolley since 2015.It mainly includes four subsystems:drive system,servo system,flaw detection system and electrical control system with character of high detection efficiency,high detection accuracy,site real-time detection,convenient assemble and strong endurance etc.

为了保证道轨巡检车在轨道上运行不脱轨，不掉道，其行走轮外形尺寸参考了铁路车辆车轮相关尺寸，设计有轮缘角、踏面斜面、轮缘内侧圆弧等。同时为了上下道方便，便于搬运，车体做了轻量化的设计。帕菲特将继续研究，为铁路安全做贡献。

In order to avoid the trolley droping off from the rail,the wheel dimensions refers to the relevant dimensions of the railway vehicle wheels are designed with flange angle,tread slope,inner arc of the wheel rim,etc.Meanwhile,we apply lightweight design to make it is easy to carry.In the future,perfect will continue to study and contribute to railway safety.
