Bridge simply supported-continuous hogging moment tensioning trolley
The invention discloses a bridge simply supported-continuous hogging moment tensioning trolley, which comprises a bottom support; an outer steel pipe is vertically and upwards arranged in the middle of the bottom support; an inner steel pipe penetrates into the outer steel pipe; two vertically upward angle steels are symmetrically arranged on the outer wall of the outer steel pipe; the top ends ofthe two angle steels are connected with the bottom of the supporting steel plate; two mounting steel plates are fixed on the surface of the supporting steel plate; a pulley is arranged between the mounting steel plates; a penetrating hole is formed in the supporting steel plate below the pulley; the steel wire rope is connected with the top of the inner steel pipe after passing through the pulleyand the penetrating hole; the other end of the steel wire rope is connected with a winch; the winch is connected with a motor; the bottom of the inner steel pipe is connected with a sliding rail; andone end of the sliding rail is rotationally connected with a jack mounting plate which is provided with a jack. According to the trolley, the jack is lifted through a rotating and telescopic structure, one-time numerical control tensioning of a whole bundle of steel strands can be achieved, the working intensity is greatly reduced, the stress of the same bundle of steel strands is uniform, and the purpose of numerical control tensioning is achieved.
本发明公开了一种桥梁先简支后连续负弯矩张拉台车，包括有底部支架，底部支架的中间竖直向上设置有1根外钢管，外钢管内部穿入1根内钢管，外钢管外壁对称设有2根竖直向上的角钢，2根角钢顶端与支撑钢板底部连接，支撑钢板表面固定有2块安装钢板，安装钢板之间设有滑轮，滑轮下方的支撑钢板上设有穿入孔，钢丝绳经滑轮以及穿入孔后，与内钢管顶部连接，钢丝绳另一端与卷扬机连接，卷扬机与电动机连接，内钢管的底部连接有滑轨，滑轨的一端转动连接有千斤顶安装板，千斤顶安装板上安装有千斤顶。该台车利用旋转、伸缩结构托举千斤顶，可实现整束钢绞线一次数控张拉，将大大降低工作强度、同束钢铰线受力均匀、实现数控张拉的目的。
