新型高强度铁路路基捣固镐头的研发应用

The research of new high strength tamper used in railway embankment construction

目前,具有国际领先水平的国产首台三枕连续式捣固稳定车在中国铁建昆明中铁集团公司下线。而与之配套使用的铁路路基捣固镐头,是铁路路基维护过程中,消耗量最大、工况最恶劣的易损易耗工具。本文从分析捣镐的工作原理及其两种失效形式(磨损与断裂)入手,对捣镐进行了改进研究,在硬质合金牌号选择、焊料与焊剂的选用、焊接工艺技术、焊接设备选型四个方面进行了创新和改进。研发的新型捣固镐头,机械性能和质量稳定性全面提升,使用寿命大幅度提高。

Nowadays, the first been made in China by China railway the machine, consumed greatly and tamping machine which was in international advanced level has machinery CO. LTD.Kunming. The tamper is very important for damaged frequently during the construction. The tamper was im tampers characterize better mechanical properties and higher quality stability and received high praise from the users.
