随着铁路行业的高效开展，关于铁路车辆的维修和养护也提出了较高的请求。面对日益增加的维护需求，内窥镜维修逐步成了主流，在车辆维修行业大展神威。

工业内窥镜检测与其他无损检测方式最大的不同是，它能够直接反映出被检测物体内表面面的状况，内窥镜设备维修不需求经过数据的比照或检测人员的技艺和经历来判别缺陷的存在与否。
The biggest difference between industrial endoscope inspection and other non-destructive inspection methods is that it can directly reflect the condition of the inner surface of the inspected object. Endoscope equipment maintenance does not require data comparison or the skill and experience of the inspector to identify defects The existence or not.
并且在检测的同时，我们能够运用工业内窥镜设备对整个检测过程停止动态的录影记载或照相记载，并能对发现的缺陷停止定量剖析，丈量缺陷的长度，面积等数据。
And at the same time of inspection, we can use industrial endoscope equipment to stop dynamic video recording or photographic recording of the entire inspection process, and to quantitatively analyze the defects found to measure the length, area and other data of the defect.

总的来说内窥镜设备维修在铁路行业中的应用十分的普遍，触及到铁路工程车辆和运输车辆的开发制造，维护检修等不同的范畴，以至在铁路的基建过程，如桥梁和隧道的建造，维修中也能找到工业内窥镜的应用。那么在铁路车辆的检修工作中，内窥镜的主要应用包括齿轮箱，空心程度车轴，电动机，转向架侧架，摇枕和避震弹簧，空互换气系统检查等各方面。

In general, the application of endoscope equipment maintenance in the railway industry is very common, involving the development and manufacturing of railway engineering vehicles and transportation vehicles, maintenance and repair, and even in the railway infrastructure process, such as bridges and tunnels. The application of industrial endoscopes can also be found in construction and maintenance. Then in the maintenance of railway vehicles, the main applications of endoscopes include gearboxes, hollow axles, motors, bogie side frames, bolsters and shock absorber springs, and air interchange air system inspections.
