Radioactive emergency shielding device for density tool while drilling

The utility model relates to a while-drilling density tool radiation emergency shielding device which comprises a semi-cylinder, the outer side of the semi-cylinder is of an arc structure, a trapezoid groove is formed in the middle of the semi-cylinder, the trapezoid groove and the semi-cylinder are coaxially arranged, and a containing cavity capable of containing a density tool is formed by the trapezoid groove. The number of the inner bushings is one, and the inner bushings are arranged in the trapezoidal grooves; the two ends of the connecting plate are detachably connected with the neck bush and the semi-cylinder respectively. The radiation emergency shielding device for the density tool while drilling has the beneficial effects that the radiation emergency shielding device for the density tool while drilling can be simultaneously used for density tools of multiple specifications, effectively prevents radiation and is convenient to mount and dismount. 本实用新型涉及一种随钻密度工具放射应急屏蔽装置，包括半柱体，所述半柱体外侧圆弧结构，中部设置有梯形凹槽，所述
