Adjustable wedge for arch bridge girder jacking
The invention provides an adjustable wedge for jacking an arch bridge girder, which comprises a bent plate, a wedge plate, a top plate, a pin shaft and an adjusting screw rod, and the wedge plate, the top plate and the adjusting screw rod are placed on the bent plate; the bent plate, the wedge plate and the top plate are connected through pin shafts, the adjusting screw penetrates through a screw hole seat on the bent plate and then makes contact with a vertical top block on the lower portion of the top plate, and limiting check blocks are arranged on the two sides of the upper portion of the wedge plate. The jacking device has the beneficial effects that the jacking device can adapt to the radian change of an arch ring of the main beam, the contact area with the main beam is increased, the main beam can be better supported under different radians, the safety and stability of the jacking device for supporting the main beam are improved, the working efficiency is improved, and potential safety hazards are reduced.
本发明提供一种用于拱桥主梁顶托的可调楔子，包括弯板、楔板、顶板、销轴和调节螺杆，所述弯板上放置有楔板、顶板和调节螺杆；所述弯板、楔板、顶板之间通过销轴连接，调节螺杆穿过弯板上的螺孔座后与顶板下部的垂直顶块相接触，所述楔板的上部两侧设有限位挡块。采用本发明的有益效果是：能够适应主梁的拱圈弧度变化，增大与主梁的接触面积，能在不同的弧度下更好的实现对主梁的支撑，提高了顶托对主梁支撑的安全性和稳定性，提高了工作效率，减少了安全隐患。
