The invention discloses an expansion type construction hoist ladder cage which comprises two symmetrically-arranged portal frames. An extension guide mechanism is arranged at the bottoms of the two portal frames. First mounting racks are arranged on the two sides of the bottom of the extension guide mechanism. Two opening and closing mechanisms in left-and-right symmetry are movably mounted on thefront side and the rear side of an inner cavity of each portal frame. According to the expansion type construction hoist ladder cage, through the arrangement of the extension guide mechanism, when shipping materials are large and long, users screw off first locking nuts and second locking nuts, then the portal frames are pulled towards the two sides, first sliding pins are driven by sliding columns to slide in inner cavities of long round holes, and under the action of limiting rails, stability of ladder cage extension is guaranteed; and a first limiting mechanism can limit extension of the portal frames, stability during ladder cage extension is guaranteed, large and long materials are transported, materials do not need to be cut and welded when transported, time and labor are saved, operation is convenient and rapid, and the expansion type construction hoist ladder cage is convenient for users to use.

    本发明公开了一种扩展式施工升降机梯笼,包括两个对称设置的龙门架,两个龙门架的底部设置有延展导向机构,所述延展导向机构底部的两侧均设置有安装架一,所述龙门架内腔的前侧和后侧均活动安装有两个左右对称的开合机构。本发明通过延展导向机构的设置,在遇到装运材料较大较长时,使用者拧松锁紧螺帽一和锁紧螺帽二,然后向两侧拉动龙门架通过滑动柱带动滑动销一在长圆孔的内腔滑动,在限位轨的作用下,保证梯笼延展的稳定性,而限位机构一也能够对龙门架的延展进行限位,保证梯笼延展时的稳定性,对较大、较长的材料进行运输,不用在运输材料时对材料进行切割再焊接,省时省力,方便快捷,方便使用者使用。
