一种焊接球钢性抓取装置
摘要：
本实用新型属于建筑安装技术领域，具体涉及一种焊接球钢性抓取装置，包括固定部分和提取部分组成，所述固定部分包括两块活动连接的半圆钢条，所述两半圆钢条能绕其中一半圆钢条的一端相对转动，所述两半圆钢条能绕其中一半圆钢条的另一端相对固定；所述提取部分包括至少三条吊装吊带，所述每一吊装吊带下设有吊钩，所述吊钩固定连接于两半圆钢条上，固定连接于两半圆钢条的相邻两吊钩间隔距离相等；所述吊装吊带另一端通过一吊环汇聚成一股。本实用新型在吊装过程中不再需要在球型节点上采用其他措施，故不会因焊接、切割而产生的热量等问题对其质量产生影响。
摘要（英）：

The utility model belongs to the technical field of construction and installation, and particularly relates to a rigid gripping device for welded balls. The device comprises a fixing part and a fetching part, wherein the fixing part comprises two movably connected semicircular steel bars, and the two semicircular steel bars can rotate relatively to one end of one semicircular steel bar and can be fixed relatively to the other end of one semicircular steel bar; the fetching part comprises at least three hoisting slings, a hook is arranged under each hoisting sling and is fixedly connected with the two semicircular steel bars, and the distance between every two hooks fixedly connected with the two semicircular steel bars is equal; the other ends of the hoisting slings are gathered through a hoisting ring to form one strand. The rigid gripping device has the advantage that other measures are not needed to be taken on ball nodes during a hoisting process, so that the influence, due to problems like heat generated by welding and cutting, on the quality is avoided.
