Description

磁轨制动器电磁吸力测试装置 技术领域
本发明涉及磁轨制动器技术领域，具体的说，涉及磁轨制动器电磁吸力测试装置。
背景技术
随着高速列车、地铁、轻轨等轨道交通工具的迅猛发展，磁轨制动器作为轨道交通工具上制动系统中不可或缺的制动部件，也得到快速迅猛的发展和应用。电磁吸力是磁轨制动器的最主要技术指标，其性能的好坏直接影响磁轨制动器对列车产生制动力的大小。因此，高效准确的测量磁轨制动器的电磁吸力值对于磁轨制动器的发展和列车制动安全性具有十分重要的意义。
目前，测量磁轨制动器电磁吸力的方法有多种。常用的测量方法为：拉力机直接拉动磁轨制动器的两侧，致使磁极与轨道整体脱离，进而获得磁力大小，这种测量方法较为简单方便，一旦在测量过程中磁轨制动器两端施力不均匀，易导致接触面一端先脱开，进而影响测量结果或导致测力失败。
中国专利号CN201080055887公开了一种用于电磁制动器的检测装置，通过在制动弹簧和弹簧板之间设置用于检测制动弹簧回复力的测力计，制动弹簧朝制动轮侧激励制动臂，制动臂上安装有制动蹄片，弹簧板保持制动弹簧处于压缩变形状态，判断部分基于测力计的输出而判断电磁制动器的制动力是否在规定的正常范围以外。由此可知上述检测装置通过测量制动弹簧回复力测量制动力，这种测量方法较为适用测量电梯制动力，且是一种电磁制动器的检测装置，不适用于磁轨制动器的电磁吸力测试。
发明内容
本发明的目的是提供一种磁轨制动器电磁吸力测试装置，可高效精确的测量磁轨制动器的电磁吸力值，确保列车行车制动的可靠性和安全性。

所述限位板固定于槽体内壁，且所述测力轨块和所述弹性测力装置均位于所述槽体内部，且所述测力轨块安装于所述限位板的上方，钢板未放置磁极时，所述测力轨块下端与所述限位板上端接触；放置磁极时，所述测力轨块上端与钢轨上表面齐平且吸附于磁极上，所述测力轨块下端与限位板脱离；
所述弹性测力装置安装于所述限位板的下方，所述测力轨块与所述弹性测力装置通过中间连接杆连接，所述弹性测力装置下端与所述拉力机连接，所述拉力机自下而上拉动所述弹性测力装置和所述测力轨块沿槽体内壁垂直运动。
进一步，为确保测量精确性，所述槽体为矩形槽体，所述槽体外壁与两侧钢轨固定，且所述槽体内表面设置为光滑面。
更进一步，为减小测力轨块和弹性测力装置与槽体内壁的摩擦力，所述盖板和所述槽体的内壁上分布有多个小孔，小孔内储存润滑油脂。
进一步，所述槽体内壁的四角各安装一块限位板，所述限位板上安装有缓冲测力轨块对限位块产生撞击力的软质衬垫。
进一步，为避免槽体、盖板和连接杆影响磁极对测力轨块吸力，所述盖板、槽体和连接杆均采用不导磁材质。
进一步，为确保测力轨块所受拉力值均匀变化，所述弹性测力装置采用具有缓冲作用和测力作用的矩形弹性块，弹性块内设有测量拉力值的测力传感器。
本发明与现有技术相比的有益效果为：
1)该吸力测试装置与传统测力装置相比，结构简单、测力方便，避免传统测试过程中，因接触面一端易脱开，导致测量结果不精确或测力失败；
2)为保证测力结果的准确性，盖板、槽体和连接杆均采用不导磁材质，槽体内表面设置为光滑面，且盖板和槽体的内壁上分布有多个储存润滑油脂的小孔，以避免运动摩擦对测力过程产生影响；
3)在实际测力过程中，可选取单位长度的测力轨块测量电磁吸力值，并可根据单位测力轨块长度值与电磁吸力值之间的关系，得到任意长度测力轨块的电磁吸力值，通过该测量方法可大大减小测试磁轨制动器电磁吸力的测试面积，降低磁轨制动器电磁吸力大小对钢轨测试面的敏感性，测量结果准确、稳定。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动的前提下所获得的所有其他实施例，均属于本发明的保护范围。
实施例1
参见图1和图2，磁轨制动器电磁吸力测试装置，包括钢轨1、测力轨块2、导向槽3、弹性测力装置4和拉力机5，钢轨1为分段式钢轨，分段式钢轨中间设有安装导向槽3的间隙，磁轨制动器的磁极放置于钢轨1的轨面上。
图3和图4为导向槽3的结构示意图，导向槽3垂直设置于分段式钢轨之间的间隙，且与两侧钢轨1固定。导向槽3包括槽体6、盖板7和限位板，槽体6为矩形槽体，槽体6外壁与两侧钢轨1固定，且槽体6内表面设置为光滑面。限位板固定于槽体6内壁。且在槽体6内壁的四角各安装一块限位板，限位板上安装有软质衬垫8，用以缓冲测力轨块2对限位块产生的撞击。
测力轨块2位于槽体6内部，且安装于限位板的上方，测力轨块2沿限位板上方的槽体6内壁垂直运动。未放置磁极时，测力轨块2下端与限位板上端的软质衬垫8接触；放置磁极时，测力轨块2由于吸力作用脱离限位板，测力轨块2上端与钢轨1上表面齐平且吸附于磁极上，测力轨块2下端与限位板脱离。
弹性测力装置4位于槽体6内部，且安装于限位板的下方，弹性测力装置4沿限位板下方的槽体6内壁垂直运动。弹性测力装置4上端与测力轨块2通过连接杆连接，弹性测力装置4下端通过连接杆与拉力机5连接，并由拉力机5带动弹性测力装置4和测力轨块2沿槽 体6内壁垂直运动。
盖板7可拆卸的安装于槽体6的前侧。为不影响磁极与测力轨块2之间的吸力，盖板、槽体6和连接杆均采用不导磁材质。为减小测力轨块2和弹性测力装置4沿槽体6内壁运动时的摩擦力，盖板和槽体6的内壁上分布有多个小孔，小孔内储存润滑油脂。
弹性测力装置4采用矩形弹性块，通过弹性块确保测力轨块2所受拉力值均匀变化，弹性块内设有测量拉力值的测力传感器。
该吸力测试装置的工作过程为：
测量时，选取一定长度的钢轨，将磁轨制动器的磁极放置于钢轨1的轨面上，在磁极吸力作用下，测力轨块2的下端脱离限位块，测力轨块2的上端吸附于磁轨制动器的磁极上。
启动拉力机5，通过拉力机5给弹性测力装置4施加向下的拉力，此时弹性测力装置4沿着导向槽3内壁竖直向下移动，进而将竖直向下的拉力传递给测力轨块2。弹性测力装置4继续向下运动，测力轨块2所受拉力将不断增大，当测力轨块2所受拉力与测力轨块2所受磁极吸力相等时，测力轨块2与磁极脱离。弹性测力装置4的测力传感器采集并输出最大拉力值，此时压力值即为磁极对测力轨块2的电磁吸力值。
本领域技术人员可以理解，在实际测量过程中，可选取单位长度的测力轨块2测量电磁吸力值，并可根据单位测力轨块2长度值与电磁吸力值之间的关系，得到任意长度测力轨块2的电磁吸力值，通过该测量方法可大大减小测试磁轨制动器电磁吸力的测试面积，降低磁轨制动器电磁吸力大小对钢轨测试面的敏感性，测量结果准确、稳定。
本领域技术人员可理解附图只为一个优选的实施例的示意图，附图中的工作流程并不一定是实施本发明所必须的。
最后应说明的是：以上实施例仅用于说明本发明的技术方案，而非对其进行限制，尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
