若本发明实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。
本发明实施例一种尾梁，如图1、图2所示，包括主梁11及第一支耳组12、第二支耳组13，主梁11沿长度方向的两端用于连接外部调平支腿，第一支耳组12、第二支耳组13的结构相同，其中，第一支耳组12包括一对第一支耳121，一对第一支耳121的支耳孔处均设置有回转轴承125，第一支耳组 12及第二支耳组13均连接于主梁11上，一对第一支耳121与主梁11之间留有间距，第一支耳组12、第二支耳组13相对于主梁11沿长度方向的中点相互对称，第一支耳组12、第二支耳组13均与主梁11相互垂直。具体地，各回转轴承125均焊接于支耳孔处，靠近每个回转轴承处设置有注油孔，用来注入润滑脂对回转轴承润滑。在实际使用中，外部调平支腿连接于主梁11沿长度方向的两端，第一支耳组12、第二支耳组13用于安装起竖回转轴，及在运输、装填运输物时作为车架后支撑回转点。本发明实施例一种尾梁，由于主梁11上还设置有第一支耳组12、第二支耳组13，并且两支耳组的支耳孔处设置有回转轴承，因此在向挂车上装填运输物时，能够以两支耳组作为支撑回转点，装填过程更方便，并且由于两支耳组与主梁11之间留有间距，在装填运输物的过程中不与车架产生干涉。
可选地，第一支耳组12还包括第一安装板122、第一连接板123、第一顶板、第一底板及两第一立板124，第一顶板、第一底板及两第一立板124相互连接形成“口”字形结构，两第一立板124一端与一对第一支耳121相连接，两第一立板124另一端连接于主梁11的侧壁上，第一连接板123连接于一对第一支耳121之间，第一安装板122一端连接于第一底板的远离第一支耳121的一端，第一安装板122另一端连接于主梁11的底面上。具体地，两第一立板124与一对第一支耳121之间通过角缝焊相互连接，第一安装板122与第一底板之间通过塞焊相互连接，两第一立板124、第一安装板122与主梁11相互焊接。由于支耳121通过第一顶板、第一底板及两第一立板124连接于主梁11上，一对第一支耳121之间设置有第一连接板123，因此大大增强第一支耳组12、第二支耳组13的整体刚度。
可选地，如图1、图3、图4、图5所示，主梁11沿长度方向的两端的高度高于中间的高度，上述设置有效保证车架中部与运输物体之间留有有效间隙。主梁11上设置有减重孔和漏水孔，保证主梁11能够正常使用和具有足够强度的同时做到轻量化。
可选地，主梁11包括主梁盖板、主梁底板及两主梁侧板，主梁盖板、主 梁底板及两主梁侧板相互连接形成“口”字型结构，主梁11两端形成“口”字型端口，两主梁侧板上分别连接有液压管路绞盘接口111及电缆绞盘接口112。由于主梁11两端形成“口”字型端口，便于将调平支腿安装于“口”字型端口内。
可选地，本发明实施例一种尾梁还包括两门型板131，两门型板131分别连接于主梁11的两端部，两门型板131的豁口与主梁11的“口”字型端口平齐，两门型板131顶部均高于主梁盖板。具体地，两门型板131与主梁盖板及两主梁侧板通过坡口焊接。由于装填物重量较大，在装填过程中调平支腿对于主梁盖板、主梁底板的压力载荷较大，设置门型板131能够提高门型板131与主梁盖板、主梁立板的整体结构强度，并且由于门型板131顶部高于主梁盖板，还能够有效降低门型板131的应力水平。
可选地，本发明实施例一种尾梁还包括第一上筋板组14及第二上筋板组，第一上筋板组14与第二上筋板组结构相同，第一上筋板组14及第二上筋板组在主梁11上对称设置，其中第一上筋板组14包括两上筋板单元，两上筋板单元结构相同，两上筋板单元均为一端较宽、一端较窄的薄板，两上筋板单元均连接于门型板131的高出主梁盖板的部分及主梁盖板上，并且两上筋板单元相互平行，两上筋板单元分别与两主梁侧板平齐。具体地，上筋板单元与门型板131、主梁盖板均相互焊接。第一上筋板组14及第二上筋板组的设置，提高主梁的结构强度。
可选地，本发明实施例一种尾梁还包括第一垫块组15及第二垫块组，第二垫块组与第一垫块组15结构相同，第二垫块组与第一垫块组15相互对称设置，其中第一垫块组15包括两垫块单元，两垫块单元均为长方形薄板，两垫块单元均连接于主梁盖板内壁的一端部，两垫块单元相互平行，两垫块单元端部相互平齐。具体地，两垫块单元均通过坡口焊与主梁盖板相互焊接。由于第一垫块组15及第二垫块组的设置，安装调平支腿后，第一垫块组15及第二垫块组与调平支腿直接接触，将调平支腿上的载荷传递至主梁盖板及上筋板组，防止装填运输物过程中调平支腿上载荷过大造成损坏，另一方面调平支腿上开设有与垫块单元相适应的导向槽，在安装过程中垫块单元对调平支腿具有导向 作用，保证调平支腿安装准确。
可选地，本发明实施例一种尾梁还包括第一限位块24及第二限位块，第一限位块24与第二限位块结构相同，第一限位块24与第二限位块在主梁11上的位置相互对称，其中第一限位块24为连接于主梁底板外侧一端部的凸块，第一限位块24突出于主梁11的“口”字形端部外，具体地，第一限位块24与主梁底板相互焊接。如图6所示，尾梁上的第一限位块24与支腿31上的支腿限位块311配合，在支腿31向尾梁中安装的过程中支腿限位块311与第一限位块24相互接触时，支腿31安装到位，第一限位块24起到定位及限位的作用。
