关于架桥机主机车架前辅助支撑的减载作用

Load decrement by auxiliary strut in front of main frame of bridge girder erecting equipment

以DJK140型架桥机机臂悬伸 38m工况为例 ,分析了架桥机主机车架前辅助支撑对其前转向架的减载作用 ,得出了前辅助支撑所受荷载的计算公式。在实际应用中 。

The load decrement by auxiliary strut in front of the main\|frame of the bridge girder erecting equipment is studied under the condition of the boom of DJK140 bridge girder erecting machine overhanging 38 m. The formula for computing the load on this auxiliary strut is obtained. In practical use, the user may increase or decrease the load decrement by adjusting the spacing between the auxiliary strut and the rail surface.
