一种电动汽车电池更换设备中的升降架 技术领域
本发明涉及一种电动汽车电池更换设备中的升降架。
背景技术
在对电动汽车进行自动更换电池的过程中，需要对电池进行放置，这个过程中涉及到使用升降座对电池进行升降，升降座通常由支架、驱动组件和拉绳组件组成，驱动组件和拉绳组件均设置有两组，每组驱动组件和拉绳组件配合来控制升降座的一侧的升降，这种结构存在的问题在于，由于驱动组件需要两组，增加制造成本，此外，由于两组驱动组件之间存在启动误差，容易导致升降座的两端不能同步上升和下降，从而导致升降座不能平稳的上升。
发明内容
本发明要解决的技术问题是提供一种电动汽车电池更换设备中的升降架，由一个驱动组件控制升降座的升降，降低成本，且升降座的升降更为平稳。
为了解决上述技术问题，本发明提供的技术方案如下：
一种电动汽车电池更换设备中的升降架，包括：支架；驱动组件，所述驱动组件固定在所述支架的顶部；转轴，所述转轴设置有两个，两个所述转轴的一端和所述驱动组件连接，且所述转轴和所述支架转动连接；卷线筒，所述卷线筒设置有两个，两个所述卷线筒分别固定在两个所述转轴上；升降座，所述升降座和所述支架滑动连接；拉绳组件，所述拉绳组件设置有两组，两组所述拉绳组件连接在所述升降座的两侧和两个所述卷线筒之间，所述拉绳组件包括拉绳、第一导线轮、第二导线轮、第三导线轮、第四导线轮和第五导线轮，所述第一导线轮和所述第二导线轮转动安装在所述升降座的一侧，所述第三导线轮和所述第四导线轮转动安装在所述支架的顶部，且所述第三导线轮设置在所述第一导线轮的上方相应处，所述第四导线轮设置在所述第二导线轮的上方相 应处，所述第五导线轮位于所述第三导线轮的一侧，所述拉绳的一端固定在所述卷线筒上，所述拉绳的另一端固定在所述支架的顶部，且所述拉绳依次穿过所述第三导线轮、所述第一导线轮、所述第五导线轮、所述第四导线轮和所述二滚轮。
优选的：还包括轴承座，轴承座固定在支架上，所述轴承座设置有四个，每根转轴对应设置有两个所述轴承座，所述转轴转动安装在所述轴承座上。
优选的：所述驱动组件包括电机和减速机，所述电机与所述减速机连接用于驱动所述减速机的输出轴转动，所述转轴固定在所述减速机的输出轴上。
优选的：所述支架包括底座、顶座和连杆，所述连杆设置有四个，四个所述连杆连接在所述底座和所述顶座的四个边角之间。
优选的：所述升降座的四个边角均设置有滑动组件，所述滑动组件包括第一滚轮和第二滚轮，所述第一滚轮和所述第二滚轮均转动安装在所述升降座上，且所述第一滚轮和第二滚轮间隔设置在所述升降座的边角的两侧，且所述第一滚轮和第二滚轮分别抵靠在所述连杆的两个相邻面上。
优选的：所述第一滚轮和所述第二滚轮均设置有两个。
本发明的有益效果是：驱动组件带动转轴转动，转轴的转动带动卷线筒的转动，卷线筒的转动带动拉绳收缩，拉绳的收缩带动第一导线轮和第二导线轮上升，由于转轴设置有两个，并由同一个驱动组件驱动，因此转轴同步转动，转轴的同步转动促使两组拉绳组件中的第一导线轮和第二导线轮同步上升，从而使得升降座的两端同步升降，升降更为稳定，同时由于只有一个驱动组件，因此降低了生产成本。

如图1至图4所示，
实施例一：
一种电动汽车电池更换设备中的升降架，包括：
支架1；
驱动组件，驱动组件固定在支架1的顶部；具体来说，驱动组件包括电机2和减速机3，电机2与减速机3连接用于驱动减速机3的输出轴转动；
转轴4，转轴4设置有两个，两个转轴4的一端和驱动组件连接，且转轴4和支架1转动连接；具体来说，转轴4固定在减速机3的输出轴上；
卷线筒5，卷线筒5设置有两个，两个卷线筒5分别固定在两个转轴4上；
升降座6，升降座6和支架1滑动连接；
拉绳组件，拉绳组件设置有两组，两组拉绳组件连接在升降座6的两侧和两个卷线筒5之间，拉绳组件包括拉绳7、第一导线轮8、第二导线轮9、第三导线轮10、第四导线轮11和第五导线轮12，第一导线轮8和第二导线轮9转动安装在升降座6的一侧，第三导线轮10和第四导线轮11转动安装在支架1的顶部，且第三导线轮10设置在第一导线轮8的上方相应处，第四导线轮11设置在第二导线轮9的上方相应处，第五导线轮12位于第三导线轮10的一侧，拉绳7的一端固定在卷线筒5上，拉绳7的另一端固定在支架1的顶部，且拉绳7依次穿过第三导线轮10、第一导线轮8、第五导线轮12、第四导线轮11和二滚轮9。
这样一来，驱动组件带动转轴4转动，转轴4的转动带动卷线筒5的转动，卷线筒5的转动带动拉绳7收缩，拉绳7的收缩带动第一导线轮8和第二导线 轮9上升，由于转轴4设置有两个，并由同一个驱动组件驱动，因此转轴4同步转动，转轴4的同步转动促使两组拉绳组件中的第一导线轮8和第二导线轮9同步上升，从而使得升降座6的两端同步升降，升降更为稳定，同时由于只有一个驱动组件，因此降低了生产成本。
另外的，还包括轴承座13，轴承座13固定在支架1上，轴承座13设置有四个，每根转轴4对应设置有两个轴承座13，转轴4转动安装在轴承座13上。
这样一来，便稳定地实现了转轴4和支架1的转动连接。
另外的，支架1包括底座101、顶座102和连杆103，连杆103设置有四个，四个连杆103连接在底座101和顶座102的四个边角之间。
这样一来，支架1的整体结构稳定，且成本较低。
实施例二：
在该实施例中，升降座6的四个边角均设置有滑动组件，滑动组件包括第一滚轮14和第二滚轮15，第一滚轮14和第二滚轮15均转动安装在升降座6上，且第一滚轮14和第二滚轮15间隔设置在升降座6的边角的两侧，且第一滚轮14和第二滚轮15分别抵靠在连杆103的两个相邻面上。具体来说，第一滚轮14和第二滚轮15均设置有两个。
这样一来，使得升降座6的四个边角无法横向移动，只能升降，从而使升降座6无法横向移动，只能升降，且第一滚轮14和第二滚轮15在连杆103上滑动，因此受到的阻力较小，使得升降座6能平稳顺畅地升降。
总之，以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
