The invention relates to the technical field of concrete structures, and discloses a lifting ring for large precast concrete. The lifting ring comprises a lifting rope, wherein a lifting ring body isfixedly connected to the bottom of the lifting rope, a preformed part is arranged in the lifting ring body, a bearing block is arranged at the bottom of the prefabricated part, a bearing plate is slidably connected to the top of the bearing block, extrusion springs are fixedly connected to the bottom of the bearing plate, an extrusion rod is rotatably connected to the surface of the bearing plate,supporting shafts are rotatably connected to the two sides of a transverse rod, air injection fans are fixedly connected to the sides, opposite to each other, of the two supporting shafts, inertia blocks are slidably connected to the surface of the transverse rod, and metal plates are fixedly connected to the side faces of the inertia blocks through connecting rods. According to the lifting ringfor the large precast concrete, through cooperative use of the bearing plate and an expansion airbag, the situation that the preformed part is damaged due to excessive extrusion force on the portion,making contact with the lifting ring body, of the preformed part in the lifting process is prevented.

    本发明涉及混凝土结构技术领域,且公开了一种用于大型混凝土预制件的起吊环,包括吊绳,所述吊绳的底部固定连接有吊环,所述吊环的内部设置有预制件,所述预制件的底部设置有承接块,所述承接块的顶部滑动连接有承接板,所述承接板的底部固定连接有挤压弹簧,所述承接板的表面转动连接有挤压杆,所述横杆的两侧转动连接有支撑轴,两个所述支撑轴相背的一侧固定连接有喷气扇,所述横杆的表面滑动连接有惯性块,所述惯性块的侧面通过连杆固定连接有金属板。该用于大型混凝土预制件的起吊环,通过承接板与膨胀气囊的配合使用,从而达到了在吊起预制件时,防止与吊环接触部分的挤压力过大损坏预制件的效果。
