The invention discloses a sleeve type synchronous lifting assembly capable of sealing in place, which comprises a winch, a steering adjusting pulley block, a rope distribution pulley block, a base anda sleeve assembly; the sleeve assembly is formed by sequentially sleeving more than three sleeves, and the innermost sleeve is sleeved on the base; a steering adjusting pulley block and a rope distribution pulley block are arranged on a ground foundation, the winch is arranged under the ground foundation, the steering adjusting pulley block adjusts a plurality of steel wire ropes in the verticaldirection into the horizontal direction, and then evenly distributes the steel wire ropes to hanging points of the outermost sleeve of the sleeve assemblies through the rope distribution pulley block,and meanwhile, the horizontal force is converted into vertical pulling force to pull the sleeves to ascend to realize controlled synchronous lifting of the sleeve assemblies; after the sleeves are lifted in place, the axial positioning of the adjacent sleeves is realized through bolt assemblies arranged on the sleeves, and the in-place sealing between the adjacent sleeves is achieved through extrusion deformation between the in-place sealing structures. According to the invention, a plurality of sleeves can be synchronously lifted and sealed in place, and the implementation of an integral protection scheme of a dome cover is ensured.
本发明公开了一种可到位密封的套筒式同步升降组件,包括卷扬机、转向调整滑轮组、配绳滑轮组、基座和套筒组件;套筒组件由三个以上的套筒依次套装组成,最内层的套筒套装在基座上;地面基础上安装转向调整滑轮组和配绳滑轮组,卷扬机安装在地面基础之下,转向调整滑轮组将竖直方向的多根钢丝绳调整为水平方向后通过配绳滑轮组均匀分配到套筒组件最外层套筒的吊点上,同时将水平力转化为竖直拉力牵拉套筒上升实现套筒组件受控同步升降,套筒上升到位后通过安装在套筒上的插销总成实现相邻套筒的轴向定位,通过到位密封结构之间的挤压变形实现相邻套筒间的到位密封。本发明能够实现多个套筒同步升降和到位密封,确保圆顶罩的整体防护方案的实现。
