The invention provides a self-erecting and self-demounting device and method of a cargo boom, and mainly relates to the technical field of cranes. According to the self-erecting and self-demounting device and method of the cargo boom, a base plate, a cross beam, an underframe, a lower rotating table, an upper rotating table, a pivoting support, a balance arm, a balance weight, a balance arm pull rod and the cargo boom are included, and a left sliding device and a right sliding device are arranged on the two sides of the underframe. The self-erecting and self-demounting device and method have the beneficial effects that the left sliding device and the right sliding device are mounted on the underframe, other machines for assisting in mounting are not needed in the mounting and demounting process of the cargo boom, the time and cost for mounting auxiliary hoisting equipment are saved, meanwhile, workers do not need to work in the air, risks are reduced, mounting and demounting are achieved in a platform, efficiency is higher than that of aerial demounting and mounting, and the whole construction progress can be accelerated better.
本发明提供一种起重臂自架设自拆卸的装置和方法,主要涉及起重机技术领域。一种起重臂自架设自拆卸的装置和方法,包括垫板、横梁、底架、下转台、上转台、回转支承、平衡臂、配重、平衡臂拉杆、起重臂,所述底架两侧设有左滑移装置与右滑移装置。本发明的有益效果在于:本发明通过在底架上安装左、右滑移装置,使得起重臂安装和拆卸过程中不在需要其他机械进行辅助安装,节省了安装辅助起重设备的时间和成本,同时工人不需要进行空中作业减小了风险,而且在平台内安装拆卸效率高于空中拆装,更能加快整个施工进程。
