Lead screw type adjustable joint for assembly type inner support
The invention discloses a lead screw type movable joint for an assembly type inner support. The movable joint comprises a movable assembly, a fixed assembly and a locking assembly; the movable assembly and the fixed assembly are mutually nested through a sector-ring-shaped plate and can coaxially and relatively slide; the locking assembly is arranged on a lead screw of the movable assembly; and the contact surfaces of the locking assembly and the fixed assembly are correspondingly provided with a saw-toothed disc. In the using process, when a jack applies prestress, the movable assembly and the locking assembly are separated from the fixed assembly. Due to the fact that one side of the sawtooth-shaped disc I of the fixed assembly and one side of the sawtooth-shaped disc II of the locking assembly are both flat and straight faces, reverse rotation of the locking assembly is limited, the locking assembly is also limited to move in the direction away from the fixed assembly, and loss of pre-applied axial force is effectively prevented; and meanwhile, the adjustable joint has the advantages of being good in structural integrity, free of redundant accessories, even in stress and the like.
本发明公开了一种用于装配式内支撑的丝杠式活络接头，该活络接头包括活动组件、固定组件和锁定组件。活动组件与固定组件通过扇环形板互相嵌套，二者可以同轴相对滑动。锁定组件设置在活动组件的丝杠上。锁定组件与固定组件的接触面分别设置了锯齿状碟片。在使用过程中，当千斤顶施加预应力时，活动组件连带锁定组件与固定组件分离。由于固定组件的锯齿状碟片Ⅰ与锁定组件的锯齿状碟片Ⅱ均有一侧是平直面，限制了锁定组件的反向转动，也就限制了锁定组件向远离固定组件的方向移动，有效地防止预加轴力的损失。同时，该活络接头具有结构整体性好，没有多余配件，受力均匀等优势。
