Temporary back-supporting device and method for large-span grid structure
The invention provides a large-span grid structure temporary back-supporting device and method, and belongs to the technical field of temporary back-supporting devices.The large-span grid structure temporary back-supporting device comprises a first-stage jig frame; the second-stage rack is mounted between the inner walls of the first-stage jig frame through a group of guide mechanisms; the third-stage rack is mounted between the inner walls of the second-stage rack through a group of guide mechanisms; the supporting mechanism is arranged on the lower side of the first-stage jig frame, and the supporting mechanism is connected with the first-stage jig frame and used for supporting the first-stage jig frame; a driving assembly is powered on to start, a second driven gear in the driving assembly drives a lead screw to rotate, the lead screw is in sliding fit with the lead screw to push a cross-shaped sliding block to ascend and descend, the cross-shaped sliding block drives a second-stage rack to ascend and descend, and a third-stage rack ascends and descends through a plurality of traction assemblies in the ascending and descending process of the second-stage rack. And then the multiple supporting blocks are lifted, so that the heights of the multiple supporting blocks are adjusted, and the multiple supporting blocks can adapt to supporting of maintenance points of large-span grid structures with different heights.
本发明提供一种大跨度网架结构临时回托装置及方法，属于临时回托装置技术领域，其包括一级胎架；二级台架，二级台架通过一组导向机构安装于一级胎架的内壁之间；三级台架，三级台架通过一组导向机构安装于二级台架的内壁之间；支撑机构，支撑机构设置于一级胎架的下侧，支撑机构与一级胎架相连接，用以支撑一级胎架；通电启动驱动组件，驱动组件中的第二从动齿轮带动丝杆进行旋转，丝杆通过与丝杆滑动配合推动十字滑块进行升降，十字滑块带动二级台架进行升降，二级台架的升降过程中通过多组牵引组件对三级台架进行升降，继而实现对多个支撑块进行升降，使得对多个支撑块进行高度调节，致使多个支撑块能适应不同高度的大跨度网架结构维修点支撑。
