The invention relates to the technical field of dynamic compaction machines, and discloses a dynamic compaction machine for engineering construction, which comprises a mounting block, a main body, a lifting hook and a detacher, a first air bag is fixedly connected to the top of the inner side of the main body, a second air bag is arranged in the first air bag, and an ejector rod is fixedly connected to the top of the second air bag; a gas conveying groove is formed in the ejector rod, a sliding cavity is fixedly formed in the outer side of the top of the main body, a magnetic sliding plate is slidably connected into the sliding cavity, and a gas film is fixedly connected to the top of the magnetic sliding plate through a connecting rod. By designing the main body, the first air bag, the magnetic pressing plate and the sliding hole, the lifting hook is promoted to move upwards along the sliding hole through potential energy generated when the heavy hammer is separated from the lifting hook, and the magnetic pressing plate is promoted to extrude the first air bag through upward movement of the lifting hook, so that the potential energy generated when the heavy hammer falls off is buffered; the situation that the lifting hook continuously shakes due to potential energy generated when the heavy hammer falls off is avoided, the shaking amplitude of the lifting hook is reduced, and a certain danger coefficient is reduced.

    本发明涉及强夯机技术领域,且公开了一种工程建设施工用强夯机,包括安装块、主体、吊钩和脱钩器,所述主体内侧的顶部固定连接有第一气囊,所述第一气囊内部设有第二气囊,所述第二气囊的顶部固定连接有顶杆,所述顶杆的内部开设有输气槽,所述主体顶部的外侧固定设有滑腔,所述滑腔的内部滑动连接有磁滑板,所述磁滑板的顶部通过连杆固定连接有气膜。本发明通过设计主体、第一气囊、磁压板和滑孔,通过重锤脱离吊钩时所产生的势能促使吊钩顺着滑孔上移,利用吊钩的上移促使磁压板对第一气囊进行挤压,使得重锤脱落所产生的势能得到缓冲,避免吊钩受重锤脱落的势能造成吊钩不断的晃动,减小了吊钩的晃动幅度,降低了一定的危险系数。
