The invention relates to the field of aerial work equipment, and discloses a U-shaped boom support component, U-shaped boom and aerial work equipment. The U-shaped boom support component comprises a first boom support (10) and a second boom support which is nested in the inner side of the first boom support, the first boom support comprises a first lower cover plate (11) and a second lower cover plate (12) and the second boom support comprises a first lower cover plate (11) and a second lower cover plate (12), the first lower cover plates comprise arc-shaped parts with arc-shaped cross sections and the second lower cover plates comprise arc-shaped parts with arc-shaped cross sections, and contact parts which are in slide fit with one another are arranged on the arc-shaped parts of the first boom support and on the arc-shaped parts of the second boom support correspondingly to generate contact force which forms antitorque moment when the first boom support and the second boom support rotate relatively. The contact parts are arranged to generate the contact force when the first boom support and the second boom support rotate relatively to form a torsion-resistant moment to prevent the first boom support and the second boom support from continuing to rotate relatively.
本发明涉及高空作业设备领域,公开了一种U型臂架组件、U型臂和高空作业设备,其中,所述U型臂架组件包括第一臂架(10)和嵌套在所述第一臂架内侧的第二臂架(20),所述第一臂架和所述第二臂架分别包括第一下盖板(11)和第二下盖板(21),所述第一下盖板和第二下盖板均包括横截面为弧形的弧形部,所述第一臂架的弧形部上和所述第二臂架的弧形部上分别设置彼此滑动配合的接触件,以能够在所述第一臂架和所述第二臂架发生相对转动时产生形成抗扭力矩的接触力。通过设置接触件,可以在第一臂架和第二臂架发生相对转动时产生接触力,以形成抗扭力矩,阻碍第一臂架和第二臂架继续相对转动。
