The invention relates to a truss type concrete pump truck arm support structure, and belongs to concrete pump truck arm support structures. One ends of the three main chord members are respectively welded with the inclined straight round tube, the other ends of the three main chord members are respectively welded with the double hinge lugs, the middle parts of the three main chord members are welded into a triangle through the straight web members, and the two ends of the inclined web members are respectively welded with the joints of the straight web members and the main chord members and are arranged in a W shape; the pipe clamps are fixedly connected with the inner sides of the main chord members through the open round pipes respectively, and the conveying pipe is arranged in the middle of the truss arm frame and connected with the pipe clamps in a clamped mode. The invention has the advantages of novel structure, light weight, good manufacturability, less welding amount, no initial welding deformation, easiness in installation, realization of light weight of the whole vehicle, reduction of the overall load of the structure, prolonging of the service life of each electric appliance and hydraulic element, effective reduction of oil consumption, and environmental protection.
本发明涉及一种桁架式混凝土泵车臂架结构，属于混凝土泵车臂架结构。三根主弦杆一端分别与斜直圆管焊接、另一端分别与双铰耳焊接、中间部分通过各直腹杆焊接成三角形，斜腹杆两端分别与直腹杆与主弦杆的连接处焊接、且布置为“W”形，该斜直圆管的前端分别固定连接单铰耳，管卡通过开口圆管分别与主弦杆内侧固定连接，输送管布置在桁架臂架中间、且与管卡卡接。优点是结构新颖，质轻、工艺性好、焊接量少，无初始焊接变形、易于安装，实现整车轻量化，降低结构整体负载，增加各电器、液压元件使用寿命，同时有效地降低油耗、更加环保。
