機場捷運軌道銲接設備功能簡介 Introduction to the Rail Welding Equipment in TIAA MRT System
鋼軌電動輸送設備及單軌吊車。

機場捷運之軌道銲接設備配置於青埔機廠銲軌場、蘆竹機廠銲軌場,亦可支援機廠及主線現場鋼軌銲接等所需之銲軌作業。軌道銲接設備包含電阻火花(Flash-butt)銲接機以及附屬設備包括鋼軌研磨設備、鋼軌踏面研磨設備、鋼軌垂直壓直機、鋼軌水平壓直機、拉軌器、移軌器、空氣乾燥機、柴油發電機組、壓縮空氣設備、超音波探傷儀、線形量測工具、鋼軌電動輸送設備及吊車等,能夠完整執行鋼軌銲接作業需求。機廠內銲接係將銲軌設備安置於銲軌場內進行銲軌工作等,正線現場銲接作業則應用貨櫃式銲軌設備,將銲軌設備安裝在一台23英尺的貨櫃,並安置於平板台車上由機車頭拖曳至現場進行銲接作業。
軌道銲接設備係以電阻火花銲接為長銲軌,並使鋼軌能承受包括由列車載重、熱循環及軌道支撐動態產生之應力。銲軌機由機械系統、供電系統、冷卻系統及銲接控制系統所組成,並經由可程式邏輯控制器及電腦資料擷取系統,控制銲接過程中的每個環節以確保銲接參數的正確及可靠。電腦資料擷取系統能夠擷取在銲接過程中全部之技術資料,進行資料分析以判斷銲接是否合格,並對整個銲接過程之銲接電壓、電流、位移以及壓力進行即時監測及記錄,以確認銲接品質。

The rail welding equipment is distributed in Chingpu Rail Welding Factory and Lujhu Rail Welding Factory which can be used for welding on both depot and main line rails. The equipment includes flash-butt welding machine, rail grinder machine, rail profile grinding machine, vertical rail joint bender, horizontal rail joint bender, rail tensor, rail changer, air dryer, diesel generator, air compressor, ultrasonic flaw detector, straightness measurer, rail electrical transport crane, etc which can fully accomplish all rail welding demands. For welding in the depot, the rail welding equipment is installed in the welding factory for the welding process; for welding on the main line, the welding equipment is installed into a 23 foot container, transferred onto a rail wagon and towed to the welding site by locomotives.
The flash-butt welding machine welds the rail into a long rail which can hold train load, heat cycle pressure and rail shoring dynamic stress. The welding equipment is made of mechanical system, power supply system, cooling system and a control system. The programmable logic controller and data acquisition system is responsible for ensuring the accuracy and reliability of welding parameters in the welding process. The data acquisition system can capture all technical records and conduct data analysis to determine whether the welding results are qualified. Moreover, it ensures the welding quality by monitoring and recording voltage change, current fluctuation, displacement and pressure during the entire welding process.
