The invention belongs to the technical field of auxiliary construction facilities, and relates to a base plate hoisting unit which comprises a supporting frame, an upper hoisting column, a lower hoisting column and a locking piece. The upper hoisting column is connected with the supporting frame, and the lower hoisting column is detachably connected with the upper hoisting column; the upper hoisting column comprises an upper outer pipe and an upper inner shaft which are coaxially arranged, the upper inner shaft can rotate and axially move relative to the upper outer pipe, and the lower hoisting column comprises a lower outer pipe and a lower inner shaft capable of ascending and descending; the upper outer pipe and the lower outer pipe are detachably connected, and the upper inner shaft andthe lower inner shaft are detachably connected through a threaded structure; a second driving mechanism used for driving the inner shaft to ascend and descend relative to the outer pipe is arranged on the supporting frame; the locking piece is connected with the lower end of the lower outer pipe and is in running fit with the lower outer pipe; a conversion structure is arranged between the lowerend of the lower inner shaft and the locking piece, and the lifting motion of the lower inner shaft is converted into the rotating motion of the locking piece. The hoisting columns are divided into the upper part and the lower part, the lower hoisting column is arranged in a pile of base plates in a penetrating mode before laying, the upper hoisting column and the lower hoisting column are directly in butt joint during laying, and rapid connection is achieved.

    本发明属于辅助施工设施技术领域,涉及一种垫板吊装单元,包括支撑架、上吊柱、下吊柱和锁止件;上吊柱与支撑架连接,下吊柱与上吊柱可拆卸地连接;上吊柱包括同轴设置的上外管和上内轴,上内轴能够相对于上外管转动和轴向运动,下吊柱包括下外管以及可升降的下内轴;上外管和下外管可拆卸连接,上内轴与下内轴通过螺纹结构可拆卸连接;支撑架上设置有用于驱动内轴相对于外管升降的第二驱动机构;锁止件与下外管的下端连接,并转动配合;下内轴的下端与锁止件之间设置有转换结构,将下内轴的升降运动转换为锁止件的旋转运动。本发明将吊柱分为上下两部分,铺设前下吊柱穿设在一摞垫板中,铺设时直接将上吊柱与下吊柱对接,实现快速连接。
