HORIZONTALLY FEEDING AND BRIDGING METHOD OF GIRDER BEAM BLOCK, AND APPARATUS THEREOF

摘要

PURPOSE:To facilitate the bridging dy laying horizontal feed beams on non- parallel piers, and by adopting the horizontally feeding and bridging apparatus provided with a frame moving rotationally and horizontally to a truck running on said beams, and girder bearing rollers rotating in the longitudinal direction. CONSTITUTION:In the advancing direction of a girder beam block 100, at the angle of theta, horizontal feed beams 31 are laid, and on the beams, a traveling truck 20 is run. In the mean time, the traveling truck 20 is provided with a rotational frame 10, and girder bearing rollers 12 rotating in the girder beam longitudinal-direction in contact with the girder beam block 100 and having a tuning speed change gear 15. After that, when the traveling truck 20 is driven, then wheels 21 are rotated, and by this rotational force, the girder bearing rollers 12 are rotated. Then, the tuning speed change gear 15 on the way of its conducting line is regulated. As the result, the gear is tuned to a speed according to various inclined piers at different declinations, and the rotational frame 10 can be moved rotationally to the traveling truck 20.
