Arch rib folding device for steel tube arch bridge
The invention belongs to the field of bridge construction, and discloses a steel tube arch bridge arch rib folding device which comprises a sliding rail shaft, a pair of symmetrically-arranged sliding seats are slidably clamped in the sliding rail shaft, vertically-arranged supporting shaft sets are fixed to the sliding seats, connecting blocks are fixed to the upper ends of the supporting shaft sets, and fixing plates are fixed to the positions, close to the bottoms, of the supporting shaft sets. Vertically-placed limiting rods are fixed between the fixing plates and the connecting blocks correspondingly, and vertically-placed first sliding grooves are formed in the sides, close to the limiting rods, of the supporting shaft sets correspondingly; the lifting mechanism is used for winding the pull rope to enable the adjusting mechanism to drive the arch rib to move upwards, meanwhile, the limiting rods are used for limiting and restraining the first sliding plate and the adjusting mechanism, the arch rib can be prevented from shaking under the influence of external wind power in the lifting process, and when the arch rib moves upwards to the needed position, the arch rib can be adjusted according to the radian of an arch ring of the arch bridge. And any end of the arch rib is selectively controlled to tilt to a corresponding degree, so that the arch rib can be accurately aligned and folded.
本发明属于桥梁施工领域，公开一种钢管拱桥拱肋合拢装置，包括滑轨轴，滑轨轴内滑动卡接有一对对称放置的滑座，滑座上均固定有竖直放置的支撑轴组，支撑轴组上端均固定有连接块，支撑轴组靠近底部的位置处均固定有固定板，固定板与连接块之间均固定有竖直放置的限位杆，支撑轴组靠近限位杆的一侧均开设有竖直放置的第一滑槽；本发明通过吊装机构卷收拉绳使得调节机构带动拱肋上移，同时通过限位杆对第一滑动板、调节机构的限位约束，可避免拱肋吊装过程中受外界风力影响而晃动，且当拱肋上移至所需位置处，可根据拱桥拱圈的弧度，选择性控制拱肋任一端翘起至相应程度，便于拱肋的精准对齐合拢。
