EGJQ-150轻型架桥机设计

设计说明
1、 总体结构说明：
架桥机主要结构由主梁、横联、前后中支腿、中后顶高支腿、边梁挂架、起吊天车、中系梁、操作室、液压及电气控制系统等组成。具体情况可见轻型架桥机总体图。
   2、分项说明：
    2．1、主梁
     架桥机共两道主梁，主梁长度按架50m跨设计，每一道主梁长80m，每一道主梁由8节10m长的梁段通过柱销连接组装。主梁采用“A”字形断面，断面尺寸为2.8×1.5m；两道主梁中心距为5m，净距3.5m；主梁共分为5类梁段。
l 主梁主要技术性能：
主梁外侧尺寸：长×宽×高：80×6.5×2.8（m）
设计最大起重能力：150T
适用跨径：20 — 50m
最大梁段重：7.03T
最大梁段长度:10.435m
2．1．2、主梁内力计算：
主梁采用《ALGOR FEAS》空间桁架程序进行计

Design Notes
1 shows the general structure:
Erector main structure from the main beam, cross-linking, around the legs, the legs after the roof height, beam rack, lifting crane, the tie beam, operating rooms, hydraulic and electric control system, etc.. Visible light erecting machine specific overall plan.
   2, item description:
    2.1, the main beam
     Erector were two main beam, main beam length by 50m inter-frame design, every main beam length 80m, every eight 10m from the main beam length of beam segment through the column pin connection assembly. Main Beam "A" shaped cross section, cross section dimensions of 2.8 × 1.5m; two main beam center distance of 5m, spacing 3.5m; main beam is divided into five categories Beam.
l girder main technical performance:
Outside the main beam dimensions: length × width × height: 80 × 6.5 × 2.8 (m)
Design maximum lifting capacity: 150T
For Span: 20 - 50m
Maximum Beam weight: 7.03T
The maximum beam length: 10.435m
2.1.2, the main internal force calculation:
Main Beam "ALGOR FEAS" total process of space truss
