The invention discloses a lifting appliance for a concrete cylinder, comprising: a base having a size smaller than that of the cylinder so that the base can extend into the cylinder, and having a plurality of horizontally arranged holes; the limiting ring is installed on the base, when the limiting ring abuts against the top wall of the cylinder, the base can be rotated, and at least part of the holes and all the hoisting holes are coaxially arranged in a one-to-one correspondence mode; the plurality of pin shafts are inserted into the holes and the hoisting holes to fix the base and the cylinder; according to the lifting appliance for the concrete cylinder, the base can extend into the cylinder, the base is provided with the hole matched with the lifting hole, and the pin shaft is inserted into the lifting hole and the hole in a penetrating mode to connect the cylinder with the base; during hoisting, the stress points of the cylinder are all in the hoisting holes, the tensile force received by the cylinder is close to a vertical state, and other positions of the cylinder are not stressed; the edge of the cylinder can be effectively prevented from being damaged, and the integrity of the cylinder can be further guaranteed.
本发明公开了一种用于混凝土圆筒的吊具,包括:基座,具有小于圆筒的尺寸以使得其可以伸入到圆筒内部,其上具有多个水平布置的孔洞;限位环,安装在基座上,当限位环抵靠圆筒的顶壁时,可转动基座,至少使得部分孔洞与所有吊装孔一一对应同轴布置;多个销轴,穿插在孔洞和吊装孔的内部对基座与圆筒进行固定;本发明提出的用于混凝土圆筒的吊具的基座可伸入到圆筒的内部,且基座上具有与吊装孔配合的孔洞,将销轴穿插在吊装孔和孔洞内对圆筒与基座连接;起吊时,圆筒的受力点均在吊装孔内,且圆筒收到的拉力较为接近竖直状态,圆筒的其他位置不受力;可以有效的防止圆筒边沿的损坏,可进一步保证圆筒的完整性。
