Concrete pump truck arm frame and concrete pump truck
The invention discloses a concrete pump truck arm frame. The concrete pump truck arm frame comprises an arm frame main body made of an aluminum alloy and two side shaft sleeves, wherein the arm framemain body comprises a first splicing part and a second splicing part which are C-shaped; the first splicing part and the second splicing part are oppositely spliced to form an arm frame main body in ashape of a square box; the two side shaft sleeves are respectively arranged at two ends of the arm frame main body; each side shaft sleeve is provided with an articulation mechanism for articulationand comprises a first left side sleeve and a first right side sleeve; the sections of the first left side sleeves and the second right side sleeves are inverted L-shaped; the first left side sleeves and the first right side sleeves are respectively coated on the side walls corresponding to splicing surfaces of the arm frame main body; and the sum of the widths of the tops of the first left side sleeves and the first right side sleeves is smaller than the width of the top of the arm frame main body. According to the concrete pump truck arm frame, the strength requirement of the arm frame can bemet; meanwhile, the weight of the arm frame can be reduced; the process is simple; and the manufacturing cost is low.
本发明公开了一种混凝土泵车臂架，包括：铝合金制成的臂架主体，所述臂架主体包括“C”型的第一拼接件和第二拼接件，所述第一拼接件和第二拼接件相对拼接而成方箱状的臂架主体；两个边轴套，两所述边轴套分别设置在所述臂架主体的两端，所述边轴套上设有用于铰接的铰接机构，所述边轴套包括第一左边套和第一右边套，所述第一左边套和第一右边套的截面均为倒“L”型，所述第一左边套和第一右边套分别包覆在所述臂架主体的拼接面对应的侧壁上，所述第一左边套和第一右边套的顶部宽度和小于所述臂架主体的顶部宽度。能够满足臂架的强度要求同时降低臂架的重量，工艺简单，制造成本低。
