The invention discloses an elevator with a safety protection function for constructional engineering, and relates to the technical field of building construction equipment. Comprising a first bottom plate, the first bottom plate is fixedly connected with symmetrically-distributed first electric push rods, the telescopic ends of the first electric push rods are fixedly connected with first fixing blocks, the first fixing blocks are slidably connected with symmetrically-distributed sliding rods, and telescopic frames are hinged between the symmetrically-distributed sliding rods on the symmetrically-distributed first fixing blocks; second electric push rods which are symmetrically distributed are fixedly connected to the first bottom plate, first rectangular frames are fixedly connected to the telescopic ends of the second electric push rods, first transmission rods are slidably connected between the sliding rods on the same sides of the symmetrically distributed first fixing blocks, limiting blocks are fixedly connected to the first rectangular frames, and rotating blocks are rotatably connected to the first rectangular frames. The adjacent rotating blocks are limited through the limiting blocks, and then the first transmission rods are limited, so that workers are protected, and the situation that due to the fact that the first transmission rods are abnormal, the telescopic frames rapidly contract downwards is avoided.
本发明公开了一种建筑工程用具有安全保护功能的升降机,涉及建筑施工装备技术领域。包括有第一底板,第一底板固接有对称分布的第一电动推杆,第一电动推杆的伸缩端固接有第一固定块,第一固定块滑动连接有对称分布的滑动杆,对称分布的第一固定块上对称分布的滑动杆之间铰接有伸缩架,第一底板固接有对称分布的第二电动推杆,第二电动推杆的伸缩端固接有第一矩形框,对称分布的第一固定块上同侧的滑动杆之间滑动连接有第一传动杆,第一矩形框固接有限位块,第一矩形框转动连接有旋转块。本发明通过限位块对相邻旋转块进行限位,进而对第一传动杆限位,以此对工作人员进行保护,避免因第一传动杆出现异常,导致伸缩架向下快速收缩。
