Description

吊装装置及吊装设备 技术领域
本实用新型涉及吊装装置及吊装设备，它们特别适用于电动汽车电池箱的更换。
背景技术
节能减排是未来发展必须面对的重要任务。由于传统的生物燃料所产生的温室气体对地球环境的破坏，电动汽车的需求日益增加。由于材料所限，电动汽车中的电池存在着续航里程短，充电耗时长等缺点，对于商用车辆来说，这些缺点尤为严重，因此车电分离的换电模式逐步为商用车领域所关注。
在换电基站中，电池箱的更换需要使用电池箱的吊装装置。传统的吊装装置采用钢丝绳吊装电池箱，在吊装过程中，随着钢丝绳的伸长，吊具和顶托之间柔性越大，搬运过程中发生的偏移量也越大，钢丝绳的偏移会加快连接处和钢丝绳的磨损，存在不可忽视的安全隐患。
发明内容

具体实施方式
为了对实用新型的技术特征、目的和效果有更加清楚的理解，现对照附图说明本实用新型的具体实施方式，在各图中相同的标号表示结构相同或结构相似但功能相同的部件。
在本文中，“示意性”表示“充当实例、例子或说明”，不应将在本文中被描述为“示意性”的任何图示、实施方式解释为一种更优选的或更具优点的技术方案。
为使图面简洁，各图中只示意性地表示出了与本实用新型相关的部分，它们并不代表其作为产品的实际结构。
图1为本实用新型的吊装装置的一种示意性实施方式的结构示意图。如图1所示，吊装装置100包括一个刚性伸缩机构10、一个柔性连接机构20、一个吊具30和一个导向机构40。
刚性伸缩机构10包括一个顶托12、一个伸缩结构14、一个升降机16和一个底托18。伸缩结构14的一端固定在顶托12上，升降机16与伸缩结构14连接，以带动伸缩结构14伸缩，底托18与伸缩结构14的另一端相连。柔性连接机构20连接至底托18。吊具30的一端与柔性连接机构20相连接，另一端可选择性地连接被吊装物(图1中未示)，被吊装物例如为电动车辆的电池箱。在底托18和吊具30之间采用柔性连接机构20，可保留一定的偏移量。在吊装被吊装物过程中，吊具30能够产生一定的位移量，便于吊具30和吊装物之间对位连接。
在图1所示的示意性实施方式中，导向机构40包括两对导柱42和导套44(为图面简洁起见，图中仅标注出了其中一对导柱和导套)，导柱42设置在吊具30上，导套44设置在顶托12上。
图2是沿图1中箭头II所示方向所视的吊装装置100的结构示意图。如图所示，导向机构40包括导柱42和导套44，导套44具有一个锥形接口。在吊具30沿图2中箭头所示方向上升时，导柱42随之上升，当导柱42与导套44插接后，可以防止吊具30摆动。
该吊装装置，结合了刚性伸缩机构和柔性连接机构，克服了如电池箱等重物在搬运过程中产生的大偏移量，利于消除安全隐患。柔性连接机构使吊具保留一定偏移量，方便吊具与被吊装物对接。
在图1所示的示意性实施方式中，伸缩结构14为剪式伸缩机，其结构简单，体积小，占地少。但不限于此，在其他示意性实施方式中，伸缩结构14也可以采用其它类型的刚性伸缩结构。
在图1所示的示意性实施方式中，升降机16为丝杠，丝杠与伸缩结构14螺纹连接并通过转动带动伸缩结构14伸缩。该结构简单，控制方便，无需复杂的控制设备。但不限于此，在其他示意性实施方式中，升降机16也可以采用其它的升降结构。
在示意性实施方式中，柔性连接机构20包括绳索，优选采用钢丝绳，其结构简易，种类繁多，价格低廉，操作方便。
图3和图4示意性地展示了本实用新型的吊装设备的一种示意性实施方式。如图3所示，吊装设备包括一个托架50和一个如图1所示的吊装装置100。如图4所示，托架50包括一组导轨52和一个动力装置54。吊装装置100的顶托12设置于导轨52上，通过动力装置54使吊装装置100在导轨52上沿图中所示的X方向的移动。如图3所示， 吊装装置100的吊具30吊起被吊装物60。被吊装物60可以是如电动车辆的电池箱等。
如图3和4所示，将本实用新型的吊装装置100的顶托12安装在托架50上，通过动力装置54使吊装装置100在导轨52上运动。升降机16带动伸缩结构14上下运动。使用时，还可将本实用新型的吊装设备通过托架50放置在搬运现场现有的行架轨道上用于搬运。
该吊装设备，结合了刚性伸缩机构和柔性连接机构，克服了如电池箱等重物在搬运过程中产生的大偏移量，消除安全隐患。柔性连接机构使吊具保留一定偏移量，方便吊具与被吊装物对接。吊装设备中的托架增加了运动维度，使吊装操作更为便利。
上文所列出的一系列的详细说明仅仅是针对本实用新型的可行性实施例的具体说明，它们并非用以限制本实用新型的保护范围，凡未脱离本实用新型技艺精神所作的等效实施方案或变更，如特征的组合、分割或重复，均应包含在本实用新型的保护范围之内。
