Horizontal turning device and horizontal turning method of bridge girder erection machine
The invention discloses a horizontal rotating device of a bridge girder erection machine. The horizontal rotating device comprises a main beam, two groups of middle supporting legs and two groups of auxiliary devices, the main beam comprises two beam bodies and a main beam transverse linkage hinged to the two beam bodies. Each group of middle supporting legs comprises two middle supporting leg units, a supporting leg cross beam and an adjusting mechanism, the two middle supporting leg units are respectively hinged with the two beam bodies, the two middle supporting leg units are arranged on the supporting leg cross beam in a sliding manner, and the adjusting mechanism is used for adjusting the distance between the two middle supporting leg units. Each auxiliary device comprises two auxiliary supporting legs, the two auxiliary supporting legs are installed on the two beam bodies respectively, and the two auxiliary devices and the two middle supporting legs are used for being alternately supported on the bridge deck to jack the main beam. The invention further provides a horizontal turning method of the bridge girder erection machine. According to the horizontal turning device and method for the bridge girder erection machine, the main beam and the middle supporting leg alternately and horizontally rotate, horizontal turning of the bridge girder erection machine is achieved, transition can be facilitated, and meanwhile the horizontal turning device and method can be suitable for the working condition that a precast beam and a cover beam are obliquely crossed.
本发明公开了一种架桥机水平转体装置，包括主梁、两组中支腿及两组辅助装置。主梁包括两个梁体以及与两个梁体铰接的主梁横联。每组中支腿包括两个中支腿单元、支腿横梁及调节机构，两个中支腿单元分别与两个梁体铰接，且两个中支腿单元滑动设置于支腿横梁上，调节机构用于调节两个中支腿单元之间的间距。每组辅助装置包括两个辅助支腿，两个辅助支腿分别安装于两个梁体上，两组辅助装置与两组中支腿用于交替支撑在桥面上以顶升主梁。本发明还提供了一种架桥机水平转体方法。述架桥机水平转体装置及水平转体方法，主梁和中支腿交替水平旋转，实现架桥机水平转体，因此可以便于转场，同时可以适用预制梁和盖梁斜交的工况。
