Modularized steel truss girder cable-stayed bridge girder erection crane
The invention relates to a modular steel truss girder cable-stayed bridge girder erection crane which comprises two truss sets, a middle parallel connection, a hoisting module, an anchoring walking device and a steel truss girder, the number of the truss sets is two, the two truss sets each comprise a main truss, the main trusses are arranged in parallel, and a side parallel connection is fixed between the main trusses; two ends of the middle horizontal bracing are fixedly connected with the truss group; the hoisting modules are connected to the main trusses; the anchoring walking device is connected to the bottoms of the two truss sets. The steel truss girder is fixedly arranged at the bottom of the anchoring walking device. The invention has the following beneficial effects: 1, the parallel connection and the edge parallel connection are structures for ensuring lateral stability and do not participate in main stress of hoisting, so that the structural weight is small; and 2, only the width of the middle parallel bracing needs to be adjusted when the device encounters bridges with different widths, and when the width of the bridge is small and the tonnage of the segmental beam is small, only the middle parallel bracing needs to be disassembled and the width of the boundary beam needs to be adjusted by the girder erection crane, so that a small girder erection crane is formed, and the universality is high.
本发明涉及一种模块化钢桁梁斜拉桥架梁吊机，包括桁架组、中平联、吊重模块、锚固行走装置及钢桁梁，桁架组设有两组，两组桁架组均包括主桁架，主桁架平行设置，主桁架之间固定有边平联；中平联两端与桁架组固定连接；吊重模块连接设于每个主桁架上；锚固行走装置连接设于两组桁架组底部；钢桁梁固定设于锚固行走装置底部。本发明的有益效果在于：1、本申请中平联与边平联为保证侧向稳定的结构，不参与吊重主受力，其结构重量小；2、本申请遇到不同宽度的桥梁时，仅需调整中平联宽度，当桥梁宽度较小和节段梁吨位较小时，架梁吊机只需拆除中平联、调整边梁宽度，形成小架梁吊机，通用性强。
