The invention discloses a lifting hook for hollow blocks and relates to the technical field of hollow four-leg blocks. The lifting hook comprises a lifting ring and a clamping rod. The clamping rod isused for clamping hollow bricks and further comprises an internal expansion mechanism. The internal expansion mechanism is rotatably connected with the lifting ring, the clamping rod is movably connected with the internal expansion mechanism and located on the outer side of the internal expansion mechanism, and the internal expansion mechanism is used for pushing the position of the clamping rodoutward. Assembly clamping plates are fixed to the two sides of the bottom end of the lifting ring and connected with the internal expansion mechanism through first rotation pins, a clamping part comprises a pull rod and a lower movable arm, and the pull rod is fixed to one side of the lower movable arm. Through a novel structural design of the lifting hook, the lifting hook well solves the lifting problem of dead-corner hollow cubes, the lifting ring does not need to be embedded in the cube bodies, a band is not needed either, only one worker is required to hang the lifting hook, and the lifting hook is easy to use, safe and efficient, greatly lowers the lifting cost, and improves the production efficiency.

    本发明公开了一种空心块体吊钩,涉及四脚空心方块技术领域。本发明专利包括吊环和卡抓杆,卡抓杆用于卡紧空心砖,还包括内扩机构,内扩机构与吊环转动连接,卡抓杆与内扩机构活动连接,卡抓杆位于内扩机构的外侧,内扩机构用于将卡抓杆的位置向外侧推动,吊环底端的两侧固定有配装夹板,配装夹板与内扩机构通过第一转动销连接,卡抓件包括拉杆和配动下臂,拉杆固定在配动下臂的一侧。本发明专利通过新型的吊钩结构设计,很好的解决了死角空心方块的吊装问题,不用块体上预埋吊环也不用绑带,只需要一名工人把吊钩挂入即可,使用简单,安全高效,极大的节省了吊装成本,提高了生产效率。
