Description

一种铁轨轨头磨耗仪 技术领域
本发明涉及轨道运输中的铁轨测量技术，涉及铁轨轨头垂直磨耗和侧面磨耗的测量，尤其是一种铁轨轨头磨耗仪。
 背景技术
轨道运输所用铁轨的加工和检测过程中，经常需要对各种大小不同、形状各异的铁轨进行轨头垂直和侧面磨耗测量。
现有技术的铁轨磨耗仪，一个铁轨磨耗仪只能通过轨头非工作面的轨头下部圆弧折弯处来定位，以确定该轨头的垂直磨耗和侧面磨耗的被测点位置，然后通过铁轨磨耗仪上的游标标尺或数显标尺测量出铁轨轨头的垂直磨耗和侧面磨耗值。由于在铁路的实际建设中，由于各段铁路的主要使用目的不同，铁轨的型号也有不同，不同型号的铁轨的轨头下部圆弧折弯处的弧度尺寸也不同，这样导致在检测不同型号铁轨轨头垂直磨耗和侧面磨耗的过程中，需要配备不同的型号的铁轨磨耗仪来实现精确定位，以达到精确测量的目的。
 技术问题
铁路运输部门的各个工务段因需测量不同轨型的铁轨而必须配备不同型号的铁轨磨耗仪，这样不利于轨道运输部门降低成本和进行工具管理，不能适应现代轨道运输快速发展中对不同铁轨的快速测量需求。
 技术解决方案
本发明的目的是针对现有技术的不足，提供一种可对不同规格型号轨头进行垂直磨耗和侧面磨耗快速精确检测的铁轨轨头磨耗仪，实现一支磨耗仪能同时精确与便捷测量多种轨型轨头垂直磨耗和侧面磨耗的目的。
实现本发明目的的技术方案如下：
一种铁轨轨头磨耗仪，包括底座、尺身、垂直测量部分和水平测量部分；
所述底座上端面为水平设置，底座的下部左侧设有底座斜边，中部设有底座垂直边，所述底座斜边与底座垂直边相交；尺身垂直于所述底座的上端面设置在底座上，所述尺身的上部刻设有垂直磨耗轨型选择线；
所述垂直测量部分包括垂直尺框，所述垂直尺框滑动安装在所述尺身上并可上下滑动；垂直尺框的顶部向左侧延伸形成尺框爪，在所述尺框爪的前部下端设有尺框爪测头；
垂直数显装置，所述垂直数显装置设置在所述垂直尺框的下部；
垂直尺框游标，所述垂直尺框游标设置在所述垂直尺框的上部；
所述水平测量部分包括水平尺框，所述水平尺框设置在所述垂直尺框的中上部，
水平测杆，所述水平测杆的左端顶部为水平测杆测头，所述水平测杆的左部刻设有水平测杆轨型选择线；
水平数显装置，所述水平数显装置设置在所述水平尺框的右部；
水平尺框游标，所述水平尺框游标刻设有水平尺框游标定位线；所述水平尺框游标设置在所述水平尺框的左部；所述水平尺框游标定位线与所述水平测杆轨型选择线相对应；
所述水平测杆滑动安装在所述水平尺框上并可左右滑动。
进一步地，包括手柄，所述手柄为框式手柄，所述手柄的上部与所述尺身的上部连接，手柄的下部与所述底座连接。
上述的铁轨轨头磨耗仪测量铁轨轨头的垂直磨耗和侧面磨耗的测量方法，包括如下步骤：
1）根据被测铁轨轨型，调节垂直尺框的位置，使垂直尺框上的垂直尺框游标上斜边的上边缘与尺身上的轨型选择线内的该轨型线对齐；
2）按垂直数显装置上的清零开关使显示屏置零；
3）根据被测铁轨轨型，调节水平测杆的位置，使水平尺框游标定位线与水平测杆轨型选择线内的被测铁轨轨型线对齐；
4）按水平数显装置上的清零开关使显示屏置零；
5）向上移动垂直尺框及向后移动水平测杆以让开被测铁轨轨头，同时将底座卡住被测铁轨工作边下方的铁轨底座，使底座斜边以及底座垂直边与被测铁轨底座斜边及铁轨底座垂直边紧密贴合；
6）向下移动垂直尺框，使尺框爪测头与被测铁轨顶部接触并保持；
7）向左移动水平测杆，使水平测杆测头与被测铁轨侧面接触并保持；
8）此时垂直数显装置显示屏上显示的数字即为该型被测铁的垂直磨耗，此时水平数显装置显示屏上显示的数字即为该型被测铁轨的侧面磨耗值。
本发明不采用现有的铁轨磨耗仪使用轨头下部圆弧折弯处作为垂直磨耗和侧面磨耗被测点的定位基准，或以铁轨底座底边与其侧垂直边缘交汇处作为垂直磨耗被测点的定位基准，而采用以下两种创新性定位方式实现了一支磨耗仪能同时精确与便捷测量多种轨型轨头垂直磨耗和侧面磨耗的目的：
1. 如图2图3所示，采用铁轨底座上斜边与铁轨底座侧垂直边的交汇点A作为定位基准点，通过该定位基准点至相应轨型垂直磨耗被测点的垂直距离确定尺框爪的伸出长度，以确保尺框爪测头的测量面始终能与所选铁轨的垂直磨耗被测点接触；同时，当垂直尺框游标的上斜边与某轨型选择线对齐时，尺框爪测头量面C1至底座斜边与底座垂直边交汇点A1的垂直距离，即C1-A1的垂直距离D1等于该型标准铁轨轨头垂直磨耗被测点C至该型标准铁轨底座上斜边与底座侧垂直边交汇点A的名义垂直距离，即标准铁轨C-A的名义垂直距离ND1；
2. 如图2图3所示，采用被测轨头顶部中心线最高处作为定位基准，根据相应国家标准中轨头顶部中心线最高处至轨头侧面磨耗被测点的垂直距离要求确定当前铁轨侧面磨耗被测点的位置（注：一个国家标准中的轨头侧面磨耗被测点对于该标准内的所有轨型都是同一位置，如加拿大铁轨标准即规定为从被测铁轨轨头顶部中心线最高处往下5/8”处作为所有轨型轨头侧面磨耗被测点）；同时，当水平尺框游标定位线与水平测杆上的某轨型选择线对齐时，水平测杆量面B1至底座斜边与底座垂直边交汇点A1的水平距离，即B1-A1的水平距离D2等于该型标准铁轨轨头侧面磨耗被测点B至该型标准铁轨底座上斜边与铁轨底座侧垂直边交汇点A的名义水平距离，即标准铁轨B-A的名义水平距离ND2。
 有益效果
采用本磨耗仪在检测铁轨轨头时，每个工务段只需一把铁轨轨头磨耗仪即可对所有型号的铁轨进行垂直磨耗和侧面磨耗的快速精确测量，结构简单，经济实用，调整灵活，适应轨道交通部门对各种轨型磨耗快速精确测量的需要。

所述水平测杆7滑动安装在所述水平尺框6上并可左右滑动。
进一步地，包括手柄10，所述手柄10为框式手柄，所述手柄10的上部与所述尺身2的上部连接，手柄10的下部与所述底座1连接。采用框式手柄使本磨耗仪方便使用者进行测量操作时握持，并有利于磨耗仪整体的结构稳定性。
具体地，尺身2垂直铆接于底座上方，在尺身2的上部刻制有多条垂直磨耗轨型选择线2-1，垂直数显装置4用螺钉紧固连接于垂直尺框3的下部，在垂直尺框上的上部用螺钉紧固连接垂直尺框游标5，水平尺框6用螺钉紧固连接在垂直尺框3上方，水平测杆7滑动安装在水平尺框6上并可前后滑动，水平测杆7刻制有多条水平测杆轨型选择线7-2，水平数显装置8用螺钉紧固连接于水平尺框6上，刻制有一条水平尺框游标定位线9-1的水平尺框游标9用螺钉紧固连接于水平尺框6左前部。
如图2图3所示，垂直尺身2上的尺身轨型选择线2-1的标注规则为：采用铁轨底座上斜边与铁轨底座侧垂直边的交汇点A作为定位基准点，通过该定位基准点至相应轨型垂直磨耗被测点的垂直距离确定尺框爪3-1的伸出长度，以确保尺框爪测头3-2的测量面始终能与所选铁轨12的垂直磨耗被测点接触；同时，当垂直尺框游标上斜边5-1与某轨型选择线对齐时，尺框爪测头量面C1至底座斜边与底座垂直边交汇点A1的垂直距离，即C1-A1的垂直距离D1等于该型标准铁轨轨头垂直磨耗被测点C至该型标准铁轨底座上斜边与底座侧垂直边交汇点A的名义垂直距离，即标准铁轨C-A的名义垂直距离ND1；
如图2图3所示，水平测杆7上的水平测杆轨型选择线7-2的标注规则为：采用被测轨头顶部中心线最高处作为定位基准，根据相应国家标准中轨头顶部中心线最高处至测量轨头侧面磨耗被测点的垂直距离要求确定当前铁轨侧面磨耗被测点的位置（注：一个国家标准中的轨头侧面磨耗被测点对于该标准内的所有轨型都是同一位置，如加拿大铁轨标准即规定为从被测铁轨轨头顶部中心线最高处往下5/8”处作为所有轨型轨头侧面磨耗被测点）；同时，当水平尺框游标定位线9-1与水平测杆7上的某轨型选择线对齐时，水平测杆量面B1至底座斜边与底座垂直边交汇点A1的水平距离，即B1-A1的水平距离D2等于该型标准铁轨轨头侧面磨耗被测点B至该型标准铁轨底座上斜边与铁轨底座侧垂直边交汇点A的名义水平距离，即标准铁轨B-A的名义水平距离ND2。
如图4所示，上述的铁轨轨头磨耗仪测量133RE型铁轨轨头的垂直磨耗和侧面磨耗的测量方法，包括如下步骤：
1）根据被测铁轨11轨型，调节垂直尺框3的位置，使垂直尺框3上的垂直尺框游标上斜边5-1的上边缘与尺身轨型选择线2-1内的133RE轨型线对齐；
2）按垂直数显装置4上的清零开关使显示屏置零；
3）根据被测铁轨11轨型，调节水平测杆7的位置，使水平尺框游标定位线9-1与水平测杆轨型选择线7-2内的133RE轨型线对齐；
4）按水平数显装置8上的清零开关使显示屏置零；
5）向上移动垂直尺框3及向后移动水平测杆7以让开铁轨轨头，同时将底座1卡住被测铁轨11工作边下方的铁轨底座，使底座斜边1-1以及底座垂直边1-2与被测铁轨底座斜边及铁轨底座垂直边紧密贴合；
6）向下移动垂直尺框3，使尺框爪测头3-2与被测铁轨11顶部接触并保持；
7）向前移动水平测杆7，使水平测杆测头7-1与被测铁轨11侧面接触并保持；
8）此时垂直数显装置4显示屏上显示的数字即为该133RE被测铁轨11轨头的垂直磨耗，此时水平数显装置8显示屏上显示的数字即为该133RE被测铁轨11轨头的侧面磨耗值。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的保护范围由所附权利要求及其等同物限定。
