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.
Description
technical field [0001] The invention relates to high-altitude operation equipment, in particular to a U-shaped arm frame assembly, a U-shaped arm and high-altitude operation equipment. Background technique [0002] Aerial work equipment is a special equipment that lifts operators to a designated position in the sky for installation, maintenance, rescue and other operations. Compared with other lifting construction machinery, it is a manned equipment, so it pays more attention to safety. [0003] Since the U-shaped jib has fewer welds, is convenient for built-in steel wire ropes, has good buckling resistance and smaller lateral deflection, it is more suitable for the needs of aerial work equipment. However, because the bottom of the U-shaped jib is a circular arc surface, the U-shaped combined jib (including the combined jib with multiple U-shaped jibs) has poor torsion resistance, especially when the adjacent jibs are prone to damage at the arc surface. Large relative rotat...
