The invention discloses a safety anti-falling device for house building construction, and belongs to the technical field of building construction, the safety anti-falling device comprises a mounting block, and sliding rails are symmetrically and fixedly mounted on the top wall of the mounting block; a loading mechanism; comprising a bottom plate slidably mounted on a sliding rail, a material conveying box is fixedly mounted on the top wall of the bottom plate, and a top plate is fixedly mounted on the top wall of the material conveying box. Through cooperation of a lifting plate, a first spring, an igniter and a gas generator, the first spring shrinks and drives the lifting plate to move downwards and extrude the igniter at the moment that a steel wire rope is broken, and the gas generator generates a thermal reaction under the action of the igniter and generates a large amount of nitrogen; under the action of nitrogen, a first fixing rod is pushed and gradually inserted into a first fixing groove, and then a top plate stops falling under the action of the first fixing groove and the first fixing rod, namely, the material conveying box and a bottom plate stop falling, so that major accidents caused by high falling of the material conveying box due to breakage of a steel wire rope are effectively prevented; and the effect of improving the safety is achieved.
本发明公开了一种房建施工用安全防坠装置,属于建筑施工技术领域,包括安装块,安装块的顶壁上对称固定安装有滑轨;装载机构;包括滑动安装在滑轨上的底板,底板的顶壁上固定安装有运料箱,运料箱的顶壁上固定安装有顶板。通过提拉板、第一弹簧、点火器、气体发生器的配合,在钢丝绳断裂的瞬间第一弹簧收缩并带动提拉板向下移动并挤压点火器,在点火器的作用下气体发生器发生热效反应并产生大量的氮气,然后在氮气的作用下第一固定杆被推动并逐渐插入第一固定槽内,然后在第一固定槽与第一固定杆的作用下顶板停止下坠,即此时运料箱与底板停止下降,进而有效防止钢丝绳断裂导致运料箱高坠造成重大事故,起到了提高安全性的作用。
