Bidirectional large-expansion-ratio shelter expansion mechanism
The invention provides a bidirectional large-expansion-ratio shelter expansion mechanism which comprises a frame, a guide rod, a transmission pipe and a transmission shaft, and the frame is fixedly connected with a shelter carrying vehicle; the guide rod and the transmission rod are installed on the frame in the expansion direction of the square cabin. The guide rod comprises a fixed sleeve and a movable sleeve which are coaxially nested, the fixed sleeve is fixedly connected with the frame, and the movable sleeve is fixedly connected with the expansion cabin and can move relative to the fixed sleeve in the axial direction; the transmission rod comprises a fixed sleeve and a movable sleeve which are coaxially nested, the fixed sleeve is fixedly connected with the frame, a rack is arranged on the side wall of the movable sleeve in the axial direction, and the rack can be driven by the transmission shaft to move relative to the fixed sleeve in the axial direction to drive the expansion cabin to move; and a folding bottom plate jacking mechanism is arranged on the transmission rod. The expansion type shelter has the advantages of being good in structural stability, smooth and reliable in expansion and retraction process, good in sealing performance and the like, and further expansion of the expansion type shelter in the electromagnetic shielding technology direction can be achieved.
本发明提供了一种双向大扩展比方舱扩展机构，包括框架、导向杆、传动管和传动轴，所述的框架与方舱载车固连；所述的导向杆和传动杆沿方舱扩展方向安装在框架上；所述的导向杆包括同轴嵌套的固定套管和活动套管，固定套管与所述的框架固连，活动套管与扩展舱固连，能够沿轴向相对固定套管移动；所述的传动杆包括同轴嵌套的固定套管和活动套管，固定套管与所述的框架固连，活动套管侧壁沿轴向设置有齿条，能够在传动轴的驱动下沿轴向相对固定套管移动，带动扩展舱移动；所述的传动杆上设置有折叠底板顶起机构。本发明具有结构稳定性好、扩展撤收过程平滑、可靠、密封性好等特点，能够实现扩展式方舱在电磁屏蔽技术方向的进一步拓展。
