The invention discloses an arm tail structure. The arm tail structure comprises a three-section arm tail and a four-section arm tail, pulley fixing structures are symmetrically arranged on the end face of the tail of the three-section arm, pulleys are installed on the pulley fixing structures, the rear sides of the pulley fixing structures are of open structures, and rope baffles capable of being assembled are arranged on the rear sides of the pulley fixing structures. The arm tail of the four-section arm comprises a rear side of the arm tail of the four-section arm, the rear side of the arm tail of the four-section arm is arranged to be of a stepped structure and used for compressing the space between the three-section arm and the four-section arm, and an inhaul cable head and an inhaul cable seat are installed between the arm tail of the four-section arm and the arm tail of the three-section arm and on the rear side of the arm tail of the four-section arm. The pulley fixing structure of the boom tail structure is in an open type, the cylinder head support of the oil cylinder can be assembled before the pulley, and the problem that the cylinder head support cannot be assembled after the pulley is assembled when the width of the cross section of the cargo boom is reduced is solved.

    本发明公开了一种臂尾结构,包括三节臂臂尾和四节臂臂尾;所述三节臂臂尾的端面上对称设有滑轮固定结构,所述滑轮固定结构安装有滑轮,所述滑轮固定结构的后侧设为开放式结构,所述滑轮固定结构的后侧设有可装配的绳档;所述四节臂臂尾包括四节臂臂尾后侧,所述四节臂臂尾后侧设为阶梯式结构,用于压缩三四节臂之间的空间,在所述四节臂臂尾与三节臂臂尾之间,且在四节臂臂尾后侧处安装有拉索绳头和拉索座。本发明臂尾结构的滑轮固定结构为开放式,此种结构可以实现油缸缸头支架先于滑轮装配,避免起重臂截面宽度变小时,滑轮装配完成后缸头支架将无法装配的问题。
