The invention discloses a combined cantilever crane of a tower crane, relates to the technical field of cantilever cranes, and aims to solve the problem of high mounting cost, the combined cantilever crane comprises a first single-section cantilever crane and a second single-section cantilever crane, the first single-section cantilever crane and the second single-section cantilever crane are mounted together, and the first single-section cantilever crane and the second single-section cantilever crane are mounted together. The first single-section arm frame and the second single-section arm frame are each composed of two arm frames which are installed together in an end-to-end mode, and the two arm frames are connected and fixed through a third pin shaft, a second cotter pin and a connecting rod. According to the scheme, the tower crane cargo boom is effectively modularized and is combined according to different working condition requirements. The manufacturing cost is greatly reduced, the efficiency is improved, segmented pin shaft connection is adopted under the condition that the structural safety is fully guaranteed, and assembly, disassembly and transportation are convenient. The structural design is compact and light, and the manufacturing process is simple.

    本发明公开了一种塔式起重机的组合臂架,涉及臂架的技术领域,本发明旨在解决安装成本较高的问题,本发明包括第一单节臂架和第二单节臂架,所述第一单节臂架和第二单节臂架安装在一起,所述第一单节臂架和第二单节臂架均由两个首尾安装在一起的臂架组成,两个所述臂架通过第三销轴、第二开口销、连杆连接固定。本方案有效将塔机起重臂模块化,根据不同的工况需求进行有组合。大大的降低制造成本提升了效率,在充分保证结构安全的情况下,采用分段销轴连接,便于安拆、运输。结构设计紧凑、轻巧,制造工艺简单。
