一种臂架式混凝土泵车回转机构铆焊定位装置
本技术涉及建筑建设设备领域,具体涉及一种臂架式混凝土泵车回转机构铆焊定位装置。
技术介绍
随着我国经济建设的快速发展,市场对于建筑工程机械,尤其是混凝土泵车的需求日益增大。混凝土泵车是一种常用的混凝土输送设备,混凝土泵车是利用压力将混凝土沿管道连续输送的机械设备,其主要由臂架结构、泵体和输送管组成,混凝土泵车在工作过程中,混凝土通过输送管末端软管喷出进行浇筑,施工人员可通过调整相连臂架间的俯仰角度来控制布料范围,也可以拉动末端软管水平摆动来扩大布料范围。需强调的是,其相应臂架相对于底盘或者底架的回转运动就是通过回转机构实现的。采用传统的工艺生产臂架式混凝土泵车的回转机构时,通常由工人通过划线及吊装完成回转机构部件的定位、组对和铆焊,要求每个铆工都要记录大量定位数据,并且在划线、吊装时对工人技术要求极高,即使再细致有经验的工人也很难保证尺寸精度的一致性,经常导致后端工序需要反复校正,同时也加大了焊接难度,不仅造成了回转机构生产成本上的浪费,而且还会延长回转机构的生产周期。甚至会导致整机安装精度下降,严重影响产品质量,最后导致 ...
