The invention provides a jacking device for supporting a bridge, comprising: a base, the top of which is provided with a spherical end protruding upward; the adjusting piece is rotationally connected with the spherical end and is adjustable in height; the sleeve is sleeved on the adjusting piece; the connecting piece is fixedly connected to the top end of the sleeve and is adjustable in position, the top face, far away from the sleeve, of the connecting piece forms a connecting face used for being fixedly connected with the bridge, the base is arranged on the ground, and then the height of the adjusting piece is adjusted so that the connecting face can correspond to the bottom face of the bridge. The adjusting piece is rotated and adjusted, and the position of the connecting piece is adjusted, so that the connecting face is attached to the bottom face of the bridge and fixedly connected with the bottom face of the bridge, and the bridge is supported. By arranging the connecting piece with the position capable of being adjusted, offset of the bridge can be counteracted, by arranging the adjusting piece capable of being rotationally adjusted, the included angle between the jacking device and the bridge supporting part is counteracted, uniform stress of the bridge is kept, and the stability of the bridge is improved.
本发明提供了一种供支撑桥梁的顶升装置,包括:底座,该底座的顶部形成有向上凸起的球状端;与该球状端转动连接且高度可调的调节件;套设于该调节件的套筒;以及固定连接于该套筒的顶端且位置可调的连接件,该连接件远离该套筒的顶面形成供与该桥梁固定连接的连接面,通过该底座置于地面,进而调节该调节件的高度,以使得该连接面对应于该桥梁的底面,进而转动调节该调节件并调节该连接件的位置,以使得该连接面贴合于该桥梁的底面并固定连接,以顶撑该桥梁。本发明通过设置能够位置调节的连接件,能够抵消桥梁的偏移,通过设置能够转动调节的调节件,从而抵消顶升装置和桥梁支撑部位的夹角,保持桥梁受力均匀,提高了桥梁的稳定性。
