所述第一吊挂座11为盆型钢结构，所述盆型钢结构为截面为近似盆形或带有外缘的U形的弯折钢板结构，所述第一吊挂座11的外缘通过螺栓固定在安装 框架上，所述第一弹性减振器12安装于第一吊挂座11的底部。
所述第一吊挂组件还包括第一防脱结构，所述第一防脱结构包括防脱耳14和防脱螺栓15，所述防脱耳14上设有防脱孔16，所述防脱螺栓15穿过防脱孔16横向固定在安装框架上，所述防脱孔16的侧壁与防脱螺栓15之间存在空隙，所述防脱耳14直接或间接与被悬挂的设备固定连接，在正常状态下，防脱孔16的侧壁与防脱螺栓15不接触，避免运行过程中的振动等因素导致防脱螺栓15发生松动，当螺栓松动导致被吊挂设备松动时，被吊挂的设备带动防脱耳14下降，防脱耳14通过防脱孔16吊挂在防脱螺栓15上，防止设备脱落。
所述第二吊挂座21可以为U形弯折钢板结构。所述第二吊挂座21与第二安装座23之间设有第二防脱结构25，所述第二防脱结构25为倒置的L形钢板结构，所述倒置的L形钢板结构下部的纵向钢板部分通过螺栓固定在第二安装座23上，所述倒置的L形钢板结构上部的横向钢板部分位于第二吊挂座21的底部上方且与第二吊挂座21的底部之间存在空隙，在正常状态下，第二防脱结构25与第二吊挂座21不接触，避免运行过程中的振动等因素导致第二安装座23与第二防脱结构25之间的连接螺栓发生松动，当第二弹性减振器22的中间螺栓发生松动或脱落时，第二安装座23同被吊挂的设备一起下降，带动第二防脱结构25下降，使第二防脱结构25的横向钢板部分吊挂在第二吊挂座21上，防止设备脱落。
本实施例中，所述横梁为板焊箱型梁结构，主要起到承载作用，所述第一吊挂组件和第二吊挂组件均设置于横梁上，所述纵梁由圆钢管材制成，主要起到连接作用，增加整体安装框架的强度和刚度。
如图1所示，具体地，本实施例的安装框架包括两个横梁和两个纵梁，分别为横梁Ⅰ1、横梁Ⅱ2、纵梁Ⅰ3和纵梁Ⅱ4，可以将第一吊挂组件和第二吊挂组件作为柴油机、传动装置和冷却装置等大部件的吊挂结构。柴油机与传动装置刚性连接为一体，通过三点弹性吊挂在安装框架下面，也就是通过三个第一吊挂组件吊挂在安装框架下，三个第一吊挂组件分别为第一吊挂组件Ⅰ5、第一吊挂组件Ⅱ6和第一吊挂组件Ⅲ7，柴油机上一点通过第一吊挂组件Ⅰ5吊挂在横梁Ⅱ2上，传动装置上两点通过第一吊挂组件Ⅱ6和第一吊挂组件Ⅲ7吊挂在横梁Ⅰ1上。所述冷却装置通过四点弹性吊挂在安装框架下面，每根横梁上两个吊挂点，采用弹性减振器倒垂悬挂连接结构，其中横梁Ⅰ1的端部设有两个第二吊挂组件Ⅰ8，两个第二吊挂组件Ⅰ8对称设置，使得第二防脱结构的横板部分 方向相对，防脱效果更为可靠，同理，横梁Ⅱ2的端部设有两个第二吊挂组件Ⅱ9，两个第二吊挂组件Ⅱ9也对称设置，使得第二防脱结构的横板部分方向相对，第二吊挂组件Ⅰ8和第二吊挂组件Ⅱ9的位置相对应。
本发明的实施方式并不限于同时设置第一吊挂组件和第二吊挂组件的情况，也可以根据设计需要在安装框架上设置第一吊挂组件，不设置第二吊挂组件，也可以设置第二吊挂组件，不设置第一吊挂组件，根据具体的情形进行选择即可。
以上所述的实施例仅仅是对本发明的优选实施方式进行描述，并非对本发明的范围进行限定，在不脱离本发明设计精神的前提下，本领域普通技术人员对本发明的技术方案做出的各种变形和改进，均应落入本发明权利要求书确定的保护范围内。
