UPPER LATTICE PLATE LIFTING DEVICE
To provide an upper lattice plate lifting device that allows a worker to stably pass through a lattice of the upper lattice plate.SOLUTION: An upper lattice plate lifting device (1), which is installed in an upper grid plate (101) located in a reactor of a nuclear power plant, includes two ladders (2R, 2 L) inserted into the upper lattice plate (101) to extend vertically, two poles (3R, 3 L) extending upward relative to the upper lattice plate (101), a plurality of connecting sections (4) connecting the ladders (2R, 2 L) and the poles (3R, 3 L), two plates (5R, 5 L) contacting the top of the upper lattice plate ( 101) to support the upper lattice plate lifting device (1), four hooks (6R1, 6R2, 6 L1, 6 L2) for hooking onto the upper lattice plate (101), and four clamping sections for clamping each of the four hooks (6R1, 6R2, 6 L1, 6 L2) and the upper lattice plate (101).SELECTED DRAWING: Figure 2
【課題】作業者が上部格子板の格子を安定して通過できる上部格子板昇降装置を提供する。【解決手段】上部格子板昇降装置（１）は、原子力プラントの炉内に配置された上部格子板（１０１）に設置される装置であって、上部格子板（１０１）に挿通して上下方向に伸びた２つの梯子（２Ｒ、２Ｌ）と、上部格子板（１０１）に対して上方に伸びた２つのポール（３Ｒ、３Ｌ）と、梯子（２Ｒ、２Ｌ）とポール（３Ｒ、３Ｌ）とを連結する複数の連結部（４）と、上部格子板（１０１）の上面に当接して上部格子板昇降装置（１）を支持する２つのプレート（５Ｒ、５Ｌ）と、上部格子板（１０１）に引っ掛かる４つの引っ掛け部（６Ｒ１、６Ｒ２、６Ｌ１、６Ｌ２）と、４つの引っ掛け部（６Ｒ１、６Ｒ２、６Ｌ１、６Ｌ２）の各々と上部格子板（１０１）を挟持する４つの挟持部と、を備える。【選択図】図２
