The invention provides a fabricated truss arm and a working machine. The fabricated truss arm comprises an inclined web member assembly and a plurality of chord member assemblies. The inclined web member assembly comprises a plurality of inclined web members which are sequentially installed at an angle. The two ends of each inclined web member are hinged to the two corresponding adjacent chord member assemblies. At least one inclined web member arranged adjacently is a detachable inclined web member and comprises a first inclined web member connecting rod and a second inclined web member connecting rod which are detachably connected with each other. The fabricated truss arm is provided with the inclined web member assembly and the plurality of chord member assemblies, the adjacent chord member assemblies are hinged through the inclined web members, and at least one inclined web member arranged adjacently is arranged to be the detachable inclined web member. Thus, in the unfolded state, the detachable inclined web members are matched with other inclined web members to be supported in the adjacent chord member assemblies to be assembled into a whole to be matched with the working machine to work. During transition transportation, the whole fabricated truss arm can be in a folded state by detaching the corresponding inclined web members, so that the outline space of an arm support is reduced, the cost is reduced, and the transportation requirement is met.

    本发明提供一种装配式桁架臂和作业机械,包括斜腹杆组件和多个弦杆组件;斜腹杆组件包括:依次呈角度安装的多个斜腹杆;每个斜腹杆的两端均与相邻的两个弦杆组件铰接;相邻设置的至少一斜腹杆为可拆卸斜腹杆,包括:相互可拆卸连接的第一斜腹杆连杆和第二斜腹杆连杆。本发明提供的装配式桁架臂,设有斜腹杆组件和多个弦杆组件,通过斜腹杆将相邻的弦杆组件铰接,将相邻设置的至少一斜腹杆设置为可拆卸斜腹杆。使得在展开状态时,可拆卸斜腹杆配合其它斜腹杆支撑在相邻弦杆组件中,装配成整体配合作业机械工作。而当转场运输时,能够通过将对应斜腹杆拆卸,使整个配式桁架臂呈折叠姿态,以减少臂架轮廓空间,减少成本,满足运输要求。
