Adjustable jacking for main beam of arch bridge
The adjustable jacking comprises a lead screw and a tray, the tray is arranged at the top of the lead screw, the lead screw is hinged to the tray, the tray is an arc block with the top face protruding, the top face of the arc block of the tray is provided with a through arc-shaped groove which is concaved inwards, threaded sleeves are arranged on the two sides of the upper portion of the lead screw, and the threaded sleeves are arranged in the through arc-shaped groove. Vertically upward adjusting screw rods are respectively arranged in the screw sleeves, and the threaded end parts of the adjusting screw rods are in contact with the bottom surfaces of the arc blocks of the tray. The supporting device has the beneficial effects that the supporting device can adapt to the radian change of an arch ring of the main beam, the contact area of the tray and the main beam is increased, the tray can better support the main beam at different angles, the safety and stability of supporting the main beam are improved, the loading and unloading efficiency of the jacking is improved, and potential safety hazards are reduced.
本发明提供一种用于拱桥主梁的可调顶托，包括丝杆和托盘，所述丝杆顶部设有托盘，所述丝杆与托盘铰接，所述托盘外形为顶面凸起的圆弧块，所述托盘的圆弧块顶面为设有内凹的贯通弧形凹槽，所述丝杆上部的两侧设有螺套，螺套中分别设有竖直向上的调节螺杆，所述调节螺杆的螺纹端部与托盘的圆弧块底面接触。采用本发明的有益效果是：能够适应主梁的拱圈弧度变化，增大托盘与主梁的接触面积，能在不同的角度下更好的实现托盘对主梁的支撑，提高了对主梁支撑的安全性和稳定性，提高了顶托的装卸效率，减少了安全隐患。
