在一个实施例中,升降机构130为多个,多个升降机构130间隔设置,且均与升降平台110驱动连接;其中,多个升降机构130同步可运行地设置。多个升降机构130的设置可以稳定地对升降平台110进行驱动,升降机构130可以选用两个。
如图12至图14所示,跑合试验台120还包括:固定平台122,固定平台122固定在基底100上;支撑台123,支撑台123设置在固定平台122上,支撑座121位置可调节地设置在支撑台123远离固定平台122的一端;其中,支撑台123成对设置,成对的两个支撑台123间隔设置,且支撑台123上均设置有支撑座121,成对的两个支撑台123上的支撑座121分别用于与两个轴箱2相连接。支撑座121用于与轴箱2固定连接,其位置可调节地设置在支撑台123上,以此满足不同电力机车驱动单元1的使用。
在一个实施例中,每个支撑台123上设置有两个支撑座121,用于支撑在位于车轴4上的轴箱2的两端。固定平台122通过多个垫块125安装在基底100上,垫块125及地脚螺栓可以用于调整支撑台123的平整度。可选地,垫块125为垫铁。
在一个实施例中,跑合试验台120还包括:电机支撑台124,电机支撑台124设置在固定平台122上,电机支撑台124用于支撑电力机车驱动单元1的电机。电机支撑台124的设置用于支撑电机,也可以使得电力机车驱动单元1的稳定性更好。
如图8至图11所示,升降平台110包括:活动台112,活动台112用于支撑电力机车驱动单元1的车轮3;活动电机支撑台113,活动电机支撑台113设置在活动台112上,且与电机支撑台124相对设置;其中,活动电机支撑台113相对于活动台112可移动地设置,以在活动台112由第一位置移动至第二位置时,电机支撑台124与活动电机支撑台113相接触,并驱动活动电机支撑台113向上移动,以使活动电机支撑台113支撑电机;并在活动台112由第二位置移动至第一位置时,活动电机支撑台113在自重的作用下向下移动直至与活动台112相平齐。
在一个实施例中,活动电机支撑台113的设置主要是配合电机支撑台124使用,即考虑到活动电机支撑台113的高度有限,故设置有一个活动电机支撑台113来支撑电机。在具体使用时,当活动台112移动到一定位置后,电机支撑台124与活动电机支撑台113相接触,并驱动活动电机支撑台113向上移动,以使活动电机支撑台113支撑电机。
在一个实施例中,活动电机支撑台113可拆卸地设置在活动台112上。活动电机支撑 台113相对于活动台112很容易拆卸,故可更换不同类型的活动电机支撑台113,以此满足不同电力机车驱动单元1的使用。
在一个实施例中,升降平台110包括:活动台112,活动台112用于支撑电力机车驱动单元1的车轮3;活动梯台114,活动梯台114相对于活动台112可移动地设置,以在活动台112由第一位置移动至第二位置时,基底100与活动梯台114相接触,并驱动活动梯台114向上移动,以使活动梯台114凸出活动台112;并在活动台112由第二位置移动至第一位置时,活动梯台114在自重的作用下向下移动直至与活动台112相平齐;其中,活动梯台114为多个,多个活动梯台114依次设置,且高度均不相同。高度不同的活动梯台114的设置主要是方便操作人员使用。
在一个实施例中,基底100上设置有成对的第一轨道段102,升降平台110上设置有成对的第二轨道段111;其中,当升降平台110位于第一位置时,第二轨道段111与第一轨道段102相对接,以使第二轨道段111接收第一轨道段102上的电力机车驱动单元1。第一轨道段102和第二轨道段111的设置可以方便电力机车驱动单元1的转运。其中,第一轨道段102和第二轨道段111可以为单轨或多轨,即轨距可调节。
本发明的电力机车驱动单元跑合试验台可以实现流水线作业,自动化程度高,大大减轻了工人的劳动强度,安全可靠,工作效率大幅提高。全程不再需要行车配合。工人劳动强度大大降低。且可以通过调整活动电机支撑台113适配不同车型。另外还兼容标准轨(1435mm),宽轨(1520mm)两种轨距。
