滑移支架刚性硬管护套装置
摘要：
本发明公开了一种滑移支架刚性硬管护套装置，由三件套筒焊接在一起，顶部由圆钢板封顶，形成滑移支架刚性硬管护套装置，装置上部设有上下布置的两个销孔，上面的一个销孔通过销轴与托梁连接，下面的一个销孔通过销轴与立柱连接，圆钢板与所述托梁的顶板直接接触。避免销轴受力而导致的销轴受剪切力而断裂；并避免了立柱柱头与托梁顶板直接接触而导致的立柱柱头受损。
摘要（英）：

The invention discloses a slipping support rigidity hard tube protective sleeve device. Three sleeve tubes are welded together, the top is sealed by a round steel plate, and thus the slipping supportrigidity hard tube protective sleeve device is formed, two pin holes arranged in an up-down mode are arranged on the upper part of the device, one pin hole on the upper part is connected with a bracket beam through a pin shaft, one pin hole on the lower part is connected with a stand column through a pin shaft, and the round steel plate is directly contacted with the top plate of the bracket beam.The situation that the pin shafts crack by shear force due to stress of the pin shafts is avoided; and the situation that the column head of the stand column is destroyed due to direct contact of thecolumn head of the stand column and the top plate of the bracket beam is also avoided.
