Abstract

本实用新型涉及一种紧密布置探头阵列，具体地说是用于列车车轮的在线探伤，属于超声波探伤技术领域。特征是采用第一斜探头与第二斜探头面对面布置组成斜探头对，斜探头对与双晶探头紧密相连成阵列布置，设置在阵列箱体上。所述的阵列箱体上设置接近开关组件。本实用新型结构简单、紧凑，合理；由于探头连续紧密布置，斜探头的交叉重叠测试，可以等效实现对车轮的完全覆盖测试，有效防止漏检误判。

Description

一种紧密布置探头阵列
技术领域
本实用新型涉及一种紧密布置探头阵列，具体地说是用于列车车轮的在线探伤，属于超声波探伤技术领域。
背景技术
目前，列车车轮在线探伤，探头布置是有较大间距的。不能实现对整个车轮的连续检测或等效的完全覆盖检测，可能产生漏检误判。
发明内容
本实用新型的目的在于克服上述不足之处，从而提供一种紧密布置探头阵列，可等效实现对车轮的完全覆盖测试，有效防止漏检误判。
本实用新型的主要解决方案是这样实现的：
本实用新型主要包括斜探头、双晶探头，特征是采用第一斜探头与第二斜探头面对面布置组成斜探头对，斜探头对与双晶探头紧密相连成阵列布置，设置在阵列箱体上。
所述的阵列箱体上设置接近开关组件。
本实用新型与已有技术相比具有以下优点：
本实用新型结构简单、紧凑，合理；由于探头连续紧密布置，斜探头的交叉重叠测试，可以等效实现对车轮的完全覆盖测试，有效防止漏检误判。
附图说明
图1为本实用新型结构主视示意图。
图2为本实用新型结构左视示意图。
具体实施方式
下面本实用新型将结合附图中的实施例作进一步描述：
本实用新型主要由第一斜探头1、第二斜探头2、双晶探头3、阵列箱体4及接近开关组件5组成。
本实用新型主要采用第一斜探头1与第二斜探头2面对面(相向)布置组成斜探头对，实现测试区域的交叉重叠。斜探头对与双晶探头3紧密相连成阵列布置，设置在阵列箱体4上。所述的阵列箱体4上设置接近开关组件5，接近开关5主要起测速作用。接近开关组件5数量明显少于双晶探头3的数量。
由少数探头实时触发接近开关，由接近开关的信号，计算出被测车轮的速度，再由速度计算出其它探头的耦合时刻，进行采样。以上速度计算与采样信号的激励、采样等，都由计算机程序自动实现。
