图1为本申请实施例提供的连接节第一视角的整体结构示意图。
如图1所示，本申请提供一种连接节，用于连接主臂和副臂机构，包 括架体1，架体1包括第一支杆101、第二支杆102以及第三支杆103；第二支杆102的两端分别与第一支杆101和第三支杆103的一端相连接，且第二支杆102与第三支杆103的连接处形成有第一连接孔2，第一连接孔2用于连接副臂机构的下节臂8；第一支杆101上设有第二连接孔301，第二连接孔301用于连接副臂机构的第一桅杆10；第二支杆102上设有第三连接孔401，第三连接孔401用于连接副臂机构的第二桅杆9；第一支杆101与第三支杆103远离第二支杆102的一端均形成有第四连接孔5。
相对于现有技术，本申请提供的连接节具有以下优势：
本申请提供的连接节，第一支杆101、第二支杆102以及第三支杆103组成架体1，通过第二支杆102与第三支杆103相连，且形成的第一连接孔2能够实现下节臂8与架体1的连接，通过在第一支杆101设置第二连接孔301，能够方便第一桅杆10与架体1的连接，通过在第二支杆102上设置第三连接孔401，能够方便第二桅杆9与架体1的连接，从而通过第一连接孔2、第二连接孔301以及第三连接孔401，能够将下节臂8、第二桅杆9以及第一桅杆10集成在架体1上。并且，由于第一支杆101和第三支杆103远离第二支杆102的一端形成有第四连接孔5，从而能够通过架体1，使下节臂8、第二桅杆9以及第一桅杆10快速地与起重机的主臂11相连接。
本申请中第一支杆101与第二支杆102均为圆柱形杆，由于副臂机构的下节臂8与起重吊钩相连接，因此，优选地，本申请中的第三支杆103由两块宽度大于第一支杆101和第二支杆102直径的支板组成，两块支板相对设置，第二支杆102远离第一支杆101的一端插入两块支板之间，从而保证了连接强度和对下节臂8的支撑强度。
此处需要补充说明的是，本申请中的第一支杆101和第二支杆102的连接以及第二支杆102和第三支杆103的连接均可以通过焊接的方式进行连接，从而使连接后的第一支杆101、第二支杆102以及第三支杆103能够形成稳定的架体1。
本申请中主臂呈框架结构，且远离起重机本体的一端形成有至少四个连接位，因此，本申请中的连接节为两个，且相对设置，两个连接节通过第四连接部与主臂11的连接位相连接，从而能够稳定的对下节臂8、第二 桅杆9以及第一桅杆10进行连接定位。
其中，如图1所示，第一连接部上形成有第一连接孔2；第三支杆103与竖直方向呈角度设置，且第三支杆103远离第四连接部的一端向远离第一支杆101的方向倾斜；第二支杆102与水平方向呈角度设置，且第二支杆102远离第一支杆101的一端向远离第三支杆103的第四连接部的方向倾斜，以使第一连接孔2的孔心偏离主臂11的延伸方向设置。
本申请中的第三支杆103与竖直方向呈角度设置，且远离第四连接部的一端向远离第一支杆101的方向倾斜，第二支杆102与水平方向呈角度设置，且第二支杆102远离第一支杆101的一端向远离第三支杆103的第四连接孔5的方向倾斜，能够使第二支杆102与第三支杆103的连接交点向远离第一支杆101的方向偏离于主臂11的延伸方向。
由于本申请中主臂11沿竖直方向设置，因此，第一连接孔2位于主臂11的延伸方向的外侧，一方面能够更加方便的进行下节臂8与主臂11的连接，另一方面，也能够使架体1具有更足够的空间布置第二连接孔301和第三连接孔401的位置，从而使下节臂8、第二桅杆9以及第一桅杆10和架体1连接后能够独立作业，互不干扰。
具体地，如图1所示，第一支杆101和第三支杆103之间以及第二支杆102和第三支杆103之间均设有多个加强筋6。
由于本申请中的下节臂8连接吊钩，进行起重作业，因此，通过在第一支杆101和第三支杆103之间以及第二支杆102和第三支杆103之间设置多个加强筋6，能够提升架体1的整体强度和对下节臂8的支撑强度。
进一步地，如图1所示，第三支杆103上设有提升滑轮组1031，提升滑轮组1031位于第一连接孔2与第三连接孔401之间。
由于起重机吊钩的升降控制需要经过提升滑轮组1031，且本申请中的下节臂8通过第一连接孔2与架体1相连接，因此，在第三支杆103上设置提升滑轮组1031，作业时能够直接将钢丝绳通过提升滑轮组1031与下节臂8上的吊钩相连接。
优选地，本申请中提升滑轮组1031位于第一连接孔2与第三连接孔401之间，从而能够避免提升滑轮组1031在作业时，对下节臂8的转动产生干扰。
其中，如图1所示，第一支杆101上设有滑轮支架1011，滑轮支架1011上设有导向滑轮组1012。
本申请中的滑轮支架1011与第一支杆101组成三角形结构，从而能够使导向滑轮组1012的作业更加稳定，通过在滑轮支架1011上设置的导向滑轮组1012，改变主臂11的倾斜角度。
由于第一支杆101与第三支杆103位于第二支杆102的两端，因此，使第一支杆101上的导向滑轮组1012以及第三支杆103上的提升滑轮组1031位于架体1的两端，作业时，导向滑轮组1012对架体1的力和提升滑轮组1031对架体1的力能够在一定程度上互相抵消，从而在一定程度上提升了架体1的支撑强度、连接强度以及连接稳定性。
具体地，如图1所示，滑轮支架1011上设有第一连接座3，第二连接孔301位于第一连接座3上。
通过在滑轮支架1011上设置第一连接座3，使第二连接孔301位于第一连接座3上，能够降低第一桅杆10对第一支杆101施加的力，从而提升整体装置的使用强度。
并且，由于第一桅杆10在作业时需要进行转动，因此，通过设置第一连接座3，能够避免第一桅杆10的转动对第一支杆101的磨损。
进一步地，如图1所示，第二支杆102上设有第二连接座4，第三连接孔401位于第二连接座4上。
通过设置第二连接座4能够避免第二桅杆9的转动对第二支杆102的磨损，并且，由于本申请中的第二连接座4位于第一连接孔2的后方，因此，能够使第二桅杆9的重心位于下节臂8重心的后方，从而能够在一定程度上提高下节臂8的载荷能力。
更进一步地，如图1所示，第二支杆102上设有第三连接座7，第三连接座7位于第二连接座4与第一连接孔2之间；第三连接座7上开设有定位孔701，定位孔701用于连接下节臂8的防后倾支杆801。
由于下节臂8在作业时，容易产生后倾的趋势，因此，下节臂8上通常会设置防后倾支杆801。通过在第二支杆102上设置第三连接座7，且使第三连接座7位于第二连接座4与第一连接孔2之间，并在第三连接座7上开设定位孔701，能够使防后倾支杆801远离下节臂8的一端与架体1 相连接，从而能够通过防后倾支杆801使架体1对下节臂8起到支撑作用，进而避免下节臂8的后倾。
此处需要补充说明的是，本申请中防后倾支杆801的两端与架体1和下节臂8均为转动连接，一方面避免对下节臂8的转动产生影响，另一方面，也能够保证对下节臂8起到支撑作用。
图2为本申请实施例提供的副臂机构的整体结构示意图。
此外，如图2所示，本申请提供一种副臂机构，包括上述的连接节以及变幅副臂组件或固定副臂组件；变幅副臂组件与固定副臂组件均包括下节臂8和第一桅杆10，变幅副臂组件还包括第二桅杆9；
下节臂8的一端与第一连接孔2转动连接，第一桅杆10的一端与第二连接孔301转动连接，第二桅杆9的一端与第三连接孔401转动连接。
采用本申请提供的连接节的副臂机构在作业时，可以将变幅副臂组件与连接节相连接，或将固定副臂组件与连接节相连接，从而实现变幅副臂组件或固定副臂组件与主臂的连接。
而连接节可以直接与起重机的主臂11相连接即可，运输时，使连接节与主臂11分离，由于下节臂8与第一连接孔2转动连接，第二桅杆9与第三连接孔401转动连接，第一桅杆10与第二连接孔301转动连接，因此，带有连接节的副臂机构无需进行拆装，可以直接进行运输，从而在一定程度上提升了运输效率。
并且，由于下节臂8、第二桅杆9以及第一桅杆10均能够转动至适当位置，因此，也能够在一定程度上降低副臂机构在运输时的空间占用。
优选地，本申请中下节臂8、第二桅杆9以及第一桅杆10与架体1均为铰接，保证了下节臂8、第二桅杆9以及第一桅杆10能够相对架体1转动的同时，也保证了连接强度。
本申请中下节臂8、第二桅杆9以及第一桅杆10还可以通过销轴与架体1转动连接，并且，通过销轴连接能够实现下节臂8、第二桅杆9以及第一桅杆10与架体1之间的可拆卸连接，当需要对其中某一结构进行维修时，能够快速地进行拆装。
此处需要补充说明的是，在作业状态下，本申请中的第一桅杆10与连接节相对固定，第二桅杆9能够相对连接节转动。
图3为本申请提供的起重机的整体结构示意图。
如图3所示，本申请还提供一种起重机，包括上述的副臂机构以及起重机本体主臂11；主臂11呈框架结构，主臂11远离起重机主体的一端形成有多个连接位，第一支杆101的第四连接部和第三支杆103的第四连接部与多个连接位相连接，以使副臂机构与主臂11相连接。
由于本申请提供的副臂机构可以将下节臂8、第二桅杆9以及第一桅杆10均集成在连接节上，且连接节上开设有第四连接孔5，因此，作业时，通过第四连接孔5能够直接将副臂机构与主臂11相连接，从而能够快速地完成起重机吊臂的组装，进而在一定程度上提升了作业效率。
此处需要补充说明的是，本申请中架体1与主臂11为可拆卸连接，当需要运输时，通过将架体1拆下，使副臂机构与主臂11相分离。
由于起重机的主臂11通常由多个臂架组成，因此，本申请中的架体1也可以与主臂11的其中一部分臂架相连接，安装时，直接将臂架与主臂11进行安装即可。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
