The invention discloses a jib luffing linkage mechanism, which relates to the technical field of high-altitude operation and comprises a base, a jib assembly, a connecting rod telescopic assembly and a driving assembly. The connecting rod telescopic assembly is connected between the base and the arm frame assembly, and the connecting rod telescopic assembly forms a shear fork type structure; the driving assembly is arranged on the connecting rod telescopic assembly, is in transmission connection with the arm frame assembly and can drive the arm frame assembly to move and change amplitude. According to the jib luffing linkage mechanism, the jib assembly is high in stability during luffing, the required length of the jib assembly is short at the same operation height, and deflection is reduced.
本发明公开了一种臂架变幅联动机构,涉及高空作业技术领域,包括底座、臂架组件、连杆伸缩组件和驱动组件。连杆伸缩组件连接在底座和臂架组件之间,且连杆伸缩组件形成剪叉式结构;驱动组件设置于连杆伸缩组件,驱动组件与臂架组件传动连接,能够驱动臂架组件移动变幅。本发明的臂架变幅联动机构,臂架组件变幅时稳定性高,在同样作业高度,臂架组件所需长度较短,减少挠度。
