具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出。下面通过参考附图 描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面结合附图1和图2具体描述根据本公开实施例的轨道梁组件100。
根据本公开实施例的轨道梁组件100包括：第一轨道梁10、关节轴承20、第二轨道梁30和连接轴40。第一轨道梁10上设有第一轴承座11，关节轴承20设在第一轴承座11内。第二轨道梁30上设有第二轴承座31。连接轴40穿过关节轴承20和第二轴承座31以连接第一轨道梁10和第二轨道梁30。
换言之，该轨道梁组件100主要由第一轨道梁10、关节轴承20、第二轨道梁30和连接轴40组成。第一轴承座11布置在第一轨道梁10上，第二轴承座31布置在第二轨道梁30上。在第一轴承座11内布置有关节轴承20，连接轴40可以穿过关节轴承20和第二轨道梁30上的第二轴承座31，以实现第一轨道梁10和第二轨道梁30的连接。
通过在第一轴承座11内设置有关节轴承20，且连接轴40穿过关节轴承20和第二轴承座31，不仅实现用于轨道梁转辙的组合形式的装置，并且可以将第一轨道梁10和第二轨道梁30进行相连，使其形成为一个整体，结构更加整体化。
由此，根据本公开实施例的轨道梁组件100，通过将关节轴承20布置在第一轨道梁10的第一轴承座11内，连接轴40穿过关节轴承20和第二轴承座31，进而将第一轨道梁10和第二轨道梁30相连接。采用关节轴承20为连接装置可以实现用于轨道梁转辙的组合形式的装置，即将关节轴承20、连接轴40和轴承座(第一轴承座11和第二轴承座31)装配为组合体，再通过组合体上第一轴承座11和第二轴承座31分别与第一轨道梁10和第二轨道梁30相连接，既可以承受较大的径向载荷，且带有密封结构，能保证具有良好的润滑环境，具有很长的使用寿命。此外，关节轴承20为标准件，可靠性高，采购十分方便，成本较低，关节轴承20的内圈可以多方向转动，装配轨道梁时较方便。该轨道梁组件100的可承受的载荷大、密封性好、使用寿命长、成本较低。
在本公开的一些具体实施方式中，第二轴承座31包括两个，两个第二轴承座31在上下方向上间隔开分布，第一轴承座11设在两个第二轴承座31之间。
也就是说，第二轨道梁30上具有两个第二轴承座31，且两个第二轴承座31沿着第二轨道梁30的竖直方向(图1中上下方向所示)间隔设置，即其中一个第二轴承座31位于另一个第二轴承座31的正上方，两个第二轴承座31之间布置有设在第一轨道梁10上的第一轴承座11，即第一轴承座11位于两个第二轴承座31之间。
通过将两个第二轴承座31上下间隔布置，且将第一轴承座11设置在两个第二轴承座31之间，使连接轴40的两端穿过第一轴承座11后、分别穿过两个第二轴承座31，进而将第一轨道梁10和第二轨道梁30相连接，使得第一轨道梁10和第二轨道梁30连接成为一个整体，且连接可靠，结构更加稳定。
在一个实施中，连接轴40可以为柱状体。如图1和图2所示，连接轴40为沿竖直方向(如图1所示的上下方向)延伸的柱状体，连接轴40可以在竖直方向上穿过第二轨道梁30上端的第二轴承座31、关节轴承20(位于第一轴承座11内)和第二轨道梁30下端的第二轴承座31，进而将第一轨道梁10和第二轨道梁30连接，使得第一轨道梁10和第二轨道梁30形成一个整体，实现整个结构的整体化。
在本公开的一些具体实施方式中，第一轨道梁10包括两个，每个第一轨道梁10上均设有第一轴承座11，第二轨道梁30的两端分别设有第二轴承座31。
换句话说，轨道梁组件100包括有两个第一轨道梁10、关节轴承20、第二轨道梁30和连接轴40。两个第一轨道梁10分别位于第二轨道梁30的左右两侧，即其中一个第一轨道梁10位于第二轨道梁30的左侧，另一个第一轨道梁10位于第二轨道梁30的右侧，在每个第一轨道梁10上均布置有第一轴承座11，位于第二轨道梁30的左侧的第一轨道梁10的右侧中部设置有第一轴承座11，位于第二轨道梁30的右侧的第一轨道梁10的左侧中部设置有第一轴承座11。
相对应地，在第二轨道梁30的左右两侧分别布置有第二轴承座31。即在第二轨道梁30的左侧布置上下间隔的两个第二轴承座31，在第二轨道梁30的右侧布置上下间隔的两个第二轴承座31。第二轨道梁30左侧的两个第二轴承座31与位于第二轨道梁30左侧的第一轨道梁10上的第一轴承座11相匹配，第二轨道梁30右侧的两个第二轴承座31与位于第二轨道梁30右侧的第一轨道梁10上的第一轴承座11相匹配，以实现第一轨道梁10与第二轨道梁30的配合相连。
可选地，第一轴承座11与关节轴承20、第二轴承座31和连接轴40装配成组合体后与第一轨道梁10和第二轨道梁30相连。
如图2所示，轨道梁组件100在组装时，首先将第一轴承座11、关节轴承20、第二轴承座31和连接轴40组装。可以先将关节轴承20装配在第一轴承座11内，然后将连接轴40穿过第一轴承座11内的关节轴承20，最后将两个第二轴承座31分别套设在连接轴40的两端，完成第一轴承座11、关节轴承20、第二轴承座31和连接轴40的组装。
进一步地，将第一轴承座11与关节轴承20、第二轴承座31和连接轴40装配成组合体后，再将装配好的组合体与第一轨道梁10和第二轨道梁30连接，即将第一轴承座11连接在第一轨道梁10上，将第二轴承座31连接在第二轨道梁30上，使关节轴承20的内圈可以多方位转动，该种装配方法使得轨道梁组件100在装配时、十分方便，装配工序简单。
在一个实施例中，组合体与第一轨道梁10和第二轨道梁30焊接或螺栓连接。
也就是说，组合体与第一轨道梁10和第二轨道梁30可以通过焊接相连，或可以通过螺栓相连，采用焊接方式将组合体与第一轨道梁10和第二轨道相连，不仅连接部件之间的 焊口牢固、耐久，严密性好，且焊缝的强度大，节省了多余的连接部件，降低了装配成本，且使用时连接可靠，不需要经常维修，施工进度快，劳动强度低。
通过螺栓连接的方式将组合体与第一轨道梁10和第二轨道相连，不仅对加工的精度要求较低，可方便对组合体与第一轨道梁10和第二轨道进行拆卸与装配，维修时更换零部件便利，且连接十分可靠，大大地加强了结构的稳定性。
在一个实施例中，第一轴承座11与第一轨道梁10一体成型，第二轴承座31与第二轨道梁30一体成型。
由此，第一轴承座11与第一轨道梁10一体形成的结构可以保证第一轨道梁10的结构、性能稳定性，第二轴承座31与第二轨道梁30一体形成的结构可以保证第二轨道梁30的结构、性能稳定性，并且方便成型、制造简单，而且省去了多余的装配件以及连接工序，大大提高了轨道梁组件100的装配效率，保证第一轨道梁10与第二轨道梁30的连接可靠性，再者，一体形成的结构的整体强度和稳定性较高，组装更方便，寿命更长。
可选地，第一轨道梁10和第二轨道梁30的端部分别设有台车50。
也就是说，在第一轨道梁10的端部布置有台车50，在第二轨道梁30的端部同样布置有台车50。多个台车50分别设置在第一轨道梁10和第二轨道梁30上，由于台车50限制轨道梁绕x轴(如图1中所示的x轴)方向的转动，使得轨道梁只能环绕Z轴(如图1中所示的z轴)轴向和Y轴(图中未示出)轴向进行转动，满足了轨道梁在转辙时的自由度需求。
在一个实施例中，台车50设在第一轨道梁10或第二轨道梁30的底部。
参照图1，台车50布置在第一轨道梁10和第二轨道梁30的底部，即台车50位于第一轨道梁10和第二轨道梁30的底部。第一轨道梁10和第二轨道梁30的下端分别与台车50固定连接，防止第一轨道梁10和第二轨道梁30绕x轴进行转动(如绕x轴进行转动，就会发生倾翻事故)。使第一轨道梁10和第二轨道梁30顺利转辙，而且相连接的第一轨道梁10和第二轨道梁30及其他梁在工作时需要时可绕Z轴轴向和Y轴轴向的转动。
当然，本公开的轨道梁组件100的结构并不限于此。第一轨道梁10的数量可以大于等于一个，例如，三个或三个以上，相邻两个第一轨道梁10之间设置一个第二轨道梁30，且相邻布置的第一轨道梁10和第二轨道梁30通过由第一轴承座11、关节轴承20、第二轴承座31和连接轴40装配成的组合体连接，装配工序简单。
下面结合具体实施例对本公开实施例的轨道梁组件100进行描述。
如图1和图2所示，根据本公开实施例的轨道梁组件100包括两个第一轨道梁10、关节轴承20、第二轨道梁30和连接轴40。在每个第一轨道梁10上均设置有第一轴承座11，在第二轨道梁30上的左右两侧均设置有两个第二轴承座31。
两个第一轨道梁10分别位于第二轨道梁30的左右两侧，在每个第一轨道梁10上均布 置有第一轴承座11，同时在第二轨道梁30的左侧和右侧分别设置有两个与第一轴承座11相对应的第二轴承座31。关节轴承20安装在第一轴承座11内，连接轴40沿竖直方向延伸形成柱状体。第一轴承座11与关节轴承20、第二轴承座31与连接轴40装配形成组合体，组合体通过焊接或者螺栓连接的方式与第一轨道梁10和第二轨道梁30相连接。
通过将关节轴承20布置在第一轨道梁10的第一轴承座11内，连接轴40穿过关节轴承20和第二轴承座31，进而将第一轨道梁10和第二轨道梁30相连接。采用关节轴承20为连接装置可以实现用于轨道梁转辙的组合形式的装置，即将关节轴承20、连接轴40和轴承座装配为组合体，再通过组合体上第一轴承座11和第二轴承座31分别与第一轨道梁10和第二轨道梁30相连接，既可以承受较大的径向载荷，且带有密封结构，能保证具有良好的润滑环境，具有很长的使用寿命。此外，关节轴承20为标准件，可靠性高，采购十分方便，成本较低，关节轴承20的内圈可以多方向转动，装配轨道梁时较方便。
因此，该轨道梁组件100的可承受的载荷大、密封性好、、使用寿命长、成本较低。
