Stepping type incremental launching construction device for steel box girder
The invention provides a stepping type pushing construction device for a steel box girder, and relates to the field of steel box girder pushing, the stepping type pushing construction device comprises two parallel first distribution girders, the first distribution girders are provided with a walking type pushing device, the walking type pushing device comprises a jacking jack, the jacking jack is used for jacking the steel box girder, the output end of the jacking jack is provided with a joist, and the joist is connected with the joist. A hydraulic push rod is arranged at the end, away from the joists, of the supporting plate, a push shaft is arranged at the output end of the hydraulic push rod, and a limiting plate is arranged at the end, close to the steel box girder, of the push shaft. According to the steel box girder pushing device, before the walking type pushing device is used for pushing the steel box girder, the hydraulic push rod can control the pushing shaft to stretch out, so that the two limiting plates abut against the two side walls of the steel box girder correspondingly, under the action of the two limiting plates, the steel box girder cannot deviate in the width direction when the steel box girder moves in the length direction during pushing, the accuracy of the position of the steel box girder in the width direction is improved, and the working efficiency is improved. And the steel box girder is accurately pushed in place.
本发明提供了一种钢箱梁的步进式顶推施工装置，涉及钢箱梁顶推领域，包括两条相互平行的第一分配梁，第一分配梁上设置步履式顶推器，步履式顶推器包括顶升千斤顶，顶升千斤顶用于顶升钢箱梁，顶升千斤顶输出端设置托梁，两个托梁相互远离一侧设置支撑板，支撑板远离托梁一端设置液压推杆，液压推杆输出端设置推动轴，推动轴靠近钢箱梁一端设置限位板。本发明中，使用步履式顶推器顶推钢箱梁前，液压推杆能控制推动轴伸出，使得两个限位板分别与钢箱梁两侧壁抵接，在两个限位板的作用下，顶推时，钢箱梁沿长度方向运动时不会在宽度方向发生偏移，提高了钢箱梁宽度方向位置的准确性，使得钢箱梁精准顶推到位。
