隨著鐵路行業(yè)的高效開展，關于鐵路車輛的維修和養(yǎng)護也提出了較高的請求。面對日益增加的維護需求，內窺鏡維修逐步成了主流，在車輛維修行業(yè)大展神威。

工業(yè)內窺鏡檢測與其他無損檢測方式最大的不同是，它能夠直接反映出被檢測物體內表面面的狀況，內窺鏡設備維修不需求經過數據的比照或檢測人員的技藝和經歷來判別缺陷的存在與否。
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.
并且在檢測的同時，我們能夠運用工業(yè)內窺鏡設備對整個檢測過程停止動態(tài)的錄影記載或照相記載，并能對發(fā)現的缺陷停止定量剖析，丈量缺陷的長度，面積等數據。
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.

總的來說內窺鏡設備維修在鐵路行業(yè)中的應用十分的普遍，觸及到鐵路工程車輛和運輸車輛的開發(fā)制造，維護檢修等不同的范疇，以至在鐵路的基建過程，如橋梁和隧道的建造，維修中也能找到工業(yè)內窺鏡的應用。那么在鐵路車輛的檢修工作中，內窺鏡的主要應用包括齒輪箱，空心程度車軸，電動機，轉向架側架，搖枕和避震彈簧，空互換氣系統(tǒng)檢查等各方面。

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.
