Description

便携式钢轨探伤车自动调节轮式探头支架
技术领域
本发明涉及一种便携式钢轨探伤车自动调节轮式探头支架,属钢轨探伤车技术领域。 
背景技术
目前,超声波轮式探头在钢轨探伤中已广为应用。但是,现有的钢轨探伤车仅是简单地将轮式探头固定在钢轨探伤车上,由于钢轨的轨距经常会有变化,因此,钢轨探伤车在运行过程中,轮式探头即随着钢轨轨距的变化而发生偏离钢轨中心线的现象,致使轮式探头难以准确的探测钢轨的轨头和轨腰范围内(包括接头附近)的疲劳缺陷和焊接缺陷,以及轨底锈蚀和月牙掉块、轨头压溃等损伤情况。 
发明内容
本发明的目的在于提供一种能够随着钢轨轨距的变化而变化、从而使探头能够始终保持在钢轨的中心线上、准确检测钢轨状况的便携式钢轨探伤车自动调节轮式探头支架。 
其技术方案是:一种便携式钢轨探伤车自动调节轮式探头支架,包括前、后钢轨行走轮和分别连接前、后钢轨行走轮的轮轴以及连接前、后轮轴的底架,其特征在于:所述连接在底架上的前、后轮轴之间,设置有由前、后轮轴联接板、悬梁、调节板和固定板构成的探头支架,悬梁的前侧一端和一边侧分别固接前、后轮轴联接板,前、后轮轴联接板的另一端分别与固接在前、后钢轨行走轮上的轴向套筒连接;悬梁的后侧两端分别固接调节板和固定板,探头安装固定在调节板和固定板之间;前、后钢轨行走轮凸缘一侧的前、后轮轴上,分别套装有弹簧。 
其技术效果是:本发明由于将安装固定有探头的探头支架固定连接在前、后钢轨行走轮的一侧,并在前、后钢轨行走轮的凸缘一侧的前、后轮轴上分别套装弹簧,利用弹簧的作用力下,使钢轨行走轮的凸缘始终紧靠钢轨的内侧,确保了钢轨行走轮随钢轨轨距的变化而变化,从而使探头始终保持在钢轨的中心线上、实现了准确检测钢轨状况的目的。其结构简单,安装、调整方便。 
附图说明
图1是本发明结构示意图; 
图2是图1的侧视图。 
具体实施方式
如图1、2所示,便携式钢轨探伤车自动调节轮式探头支架,包括前、后钢轨行走轮9和分别连接前、后钢轨行走轮的轮轴7以及连接前、后轮轴的底架8。连接在底架上的前、后轮轴7之间,设置有由前、后轮轴联接板、悬梁、调节板和固定板构成的探头支架,悬梁11的前侧一端和一边侧分别固接前、后轮轴联接板4、5,前、后轮轴联接板的另一端分别与固接在前、后钢轨行走轮9上的轴向套筒10连接。悬梁的后侧两端分别固接调节板2和固定板3,探头1安装固定在调节板和固定板之间。前、后钢轨行走轮的凸缘一侧的前、后轮轴上,分别套装有弹簧6。在弹簧的作用力下,钢轨行走轮的凸缘即始终紧靠钢轨的内侧,从而保证探头支架上的探头始终保持在钢轨的中心线上。 
为了防止钢轨行走轮在过叉道口时,套装在前、后轮轴上的弹簧将钢轨行走轮推向其行走钢轨的外侧,进而将钢轨行走轮推到另外一条钢轨上的问题发生,在悬梁11的前侧设有与拨叉12的叉口配合的端块13,拨叉的另一端通过支点14铰接在左侧顶架15上并与拨叉杆连接。当钢轨探伤车的钢轨行走轮通过叉道口时,操作人员只需通过往外推动拨叉即可将钢轨行走轮凸缘一侧的弹簧压缩,使钢轨行走轮继续在原钢轨上行走,从而避免钢轨行走轮跑到另外一条钢轨上;叉道口过后,放松拨叉,弹簧即恢复到原来的工作状态。
