Half-through arch bridge arched girder cross installation support and installation device thereof
The invention belongs to the technical field of bridge construction, and discloses a half-through arch bridge arched girder cross mounting support and a mounting device.The half-through arch bridge arched girder cross mounting support comprises a pair of symmetrically-arranged fixing bases, vertically-upwards-arranged supporting frames are fixed to the fixing bases correspondingly, and supporting plates are slidably clamped to the supporting frames correspondingly; the end, away from the supporting frame, of the supporting plate on any supporting frame extends towards the end of the other supporting frame, a pair of vertically-upwards-placed telescopic air cylinders is fixed to each supporting plate, the plane where the central axes of the two telescopic air cylinders on any supporting plate are located is parallel to the symmetrical plane of the two first screw rods, and containing grooves are fixed to the upper ends of the telescopic air cylinders. First screw rods which are coaxially arranged are arranged in the support frames; the problem that in the prior art, an installation support is poor in stability is solved, the two fixing bases are connected into a whole through the first connecting plate, the stability of the supporting frames on the two sides is improved, when a lifting arched beam moves upwards, a drill rod is synchronously inserted into a soil layer, and the stability of the installation support in the arched beam lifting process is improved.
本发明属于桥梁施工技术领域，公开一种中承式拱桥拱梁交叉安装支架及其安装装置，包括一对对称放置的固定座，固定座上均固定有竖直向上放置的支撑架，支撑架上均滑动卡接有托板，任一支撑架上的托板远离该支撑架的一端均向另一支撑架端延伸，托板上均固定有一对竖直向上放置的伸缩气缸，且任一托板上的两伸缩气缸中心轴线所在平面均与两第一螺杆对称平面呈平行放置状态，伸缩气缸上端均固定有放置槽，支撑架内均设有同轴线放置的第一螺杆；解决了现有技术中安装支架存在着稳定性较差的问题，通过第一连接板将两固定座连接形成一个整体，提高两侧支撑架的稳定性，且举升拱梁上移时，使钻杆同步插入土层中，提高举升拱梁过程中安装支架的稳定性。
