Patent number: 8251628Abstract: A joint tong apparatus for a radiation shielding facility. A spherical ball has a through-hole. An inner spherical socket and an outer spherical socket are installed in a hole formed in a partition between a radiation-shielded room and a control room so as to enclose the spherical ball on inner and outer sides. A bar is inserted and coupled into and to the through-hole of the spherical ball. An inner joint assembly has a first housing coupled to a shielded room-side end of the bar and a first pivot member pivotably mounted on a free end of the first housing. An outer joint assembly having a second housing coupled to a control room-side end of the bar and a second pivot member pivotably mounted on a free end of the second housing. The apparatus further includes a tong assembly, a handle assembly, a tong manipulation cable, and a pair of pivot manipulation cables.Type: GrantFiled: October 28, 2008Date of Patent: August 28, 2012Assignees: Korea Atomic Energy Research Institute, Korea Hydro & Nuclear Power Co., Ltd.Inventors: Eun Pyo Lee, Won Myung Choung, Dong Hee Hong, Jeong Hoe Ku, Won Kyung Lee, Il Je Cho, Dong Hak Kook, Kie Chan Kwon, Gil Sung You, Ji Sup Yoon
