Description

一种铁路施工智能防护装置 技术领域
本实用新型涉及铁路轨道养护技术领域，尤其涉及一种铁路施工智能防护装置。
背景技术
铁路轨道简称路轨、铁轨、轨道等，主要用于铁路上，并与转辙器合作，令火车无需转向便能行走。铁路轨道通常由两条平行的钢轨组成，钢轨固定放在轨枕上，轨枕之下为路碴。由轨撑、扣件、压轨器、道夹板、弹条、铁路道钉等铁路配件紧固。铁路路轨以钢铁制成的路轨，可以比其它物料承受更大的重量。轨枕亦称枕木、灰枕，或路枕，功用是将钢轨的重量及钢轨所受压力分开散布，和保持固定轨距，维持路轨的轨距。由原先木枕，改为混凝土枕。作用令火车无需转向便能行走。技术原理：轨道承受着多变化的垂直、横向、纵向的静荷载和动荷载，荷载从钢轨通过轨枕和道床传递到路基。通过力学理论，分析研究在各种荷载条件下，轨道各组成部分所产生的应力和应变，而确定其承载能力和稳定性。轨道力学分析轨道结构在机车车辆作用下的受力和变形，以及轨道结构病害对轨道破坏及列车运行的影响，为设计轨道结构，制定轨道管理标准提供依据。组成结构由轨道由道床、轨枕、钢轨、联接零件、防爬设备及道岔组成。
铁路施工的时候，需要在铁路轨道上安装防护装置，一般的防护装置仅仅只是展示正在施工的功能，往往需要车站需要给工人通知，工人才能停止施工，但是这样会增加施工的风险性，同时一般防护装置也无法测量两个轨道之间距离。
