Description

动车组变流装置防脱型底板 技术领域
本发明涉及高速动车组变流装置底部检修用底板，具体为动车组变流装置防脱型底板。
背景技术
在动车组运行过程中，为避免变流装置底部检修用底板脱落影响动车组安全运行，检修用底板需采用可靠的防脱设计。现有高速动车组上变流装置底部检修用底板的防脱设计方案为：在底板与箱体上开相应的螺栓孔，通过螺栓与变流装置箱体进行连接。以检修用底板3为例说明，检修用底板3开9个螺栓孔，通过9个螺栓连接至变流装置箱体底部。检修用底板3安装示意如图3所示，底板与箱体间的连接仅通过螺栓连接，仅有一级防脱措施。若螺栓松动掉落，底板将会脱落，影响动车组运行安全。
本发明在既有的螺栓紧固防脱结构的前提下，同时采用特殊锁具，在螺栓全部掉落的情况下，特殊锁具仍可保证底板与箱体的正常连接，实现底板的多级防脱功能。
发明内容
本发明针对上述问题，提供了动车组变流装置防脱型底板，实现高速动车组变流装置检修用底板多级防脱功能。
本发明是采用如下的技术方案实现的：动车组变流装置防脱型底板，底板上设置螺栓安装孔、拉紧锁安装孔和防脱锁安装孔，紧固螺栓安装在螺栓安装孔内，底板与箱体通过紧固螺栓进行连接，实现底板的第一级防脱；拉紧锁通过拉紧锁安装孔安装在底板上，其锁舌通过旋转，与箱体框架实现搭接，在紧固螺栓松动掉落的情况下可保证底板不会脱落，实现底板的第二级防脱，防脱锁通过防脱锁安装孔安装在底板上，其锁舌通过旋转，与箱体框架实现搭接，在紧固螺栓松动掉落且拉紧锁开启的情况下仍 可保证底板不会脱落，实现底板的第三级防脱。
变流装置底板与箱体的连接同时采用了紧固螺栓、拉紧锁、防脱锁三种连接方式，有效的实现了底板的多级防脱功能，大大降低底板脱落的风险，将因底板脱落而影响动车组运行安全的隐患降至最低。

图中：1-紧固螺栓，2-拉紧锁，3-防脱锁，4-底板。
具体实施方式
变流装置底板设置螺栓安装孔、拉紧锁安装孔、防脱锁安装孔，紧固螺栓通过相应的安装孔与箱体实现紧固，实现底板的第一级防脱；拉紧锁、防脱锁通过对应的安装孔安装在底板上，通过锁舌连接在箱体上，实现底板的第二级、第三级防脱。以检修用底板3为例说明。检修用底板3具体方案见图4。
拉紧锁具备收缩的功能，可实现底板与箱体的紧密贴合，保证箱体的密封性。同时拉紧锁也具备防脱功能，其锁舌通过旋转，与箱体框架实现搭接，在紧固螺栓松动掉落的情况下可保证底板不会脱落，实现第二级防脱功能，拉紧锁安装及内部结构示意图见图5。
防脱锁也具备防脱功能，其锁舌通过旋转，与箱体框架实现搭接，在紧固螺栓松动掉落且拉紧锁开启的情况下仍可保证底板不会脱落，实现第三级防脱功能，防脱锁安装及内部结构示意图见图8。
