Bridge limiting device used during jacking and lifting of bridge
The invention discloses a bridge limiting device used during bridge jacking and lifting, and relates to the technical field of bridge construction. The device comprises a bridge pier and a bridge deck, two sets of jacking jacks are installed on the top face of the bridge pier, jacking blocks are fixedly installed at the top ends of the jacking jacks, the jacking jacks and the jacking blocks are used for vertically jacking the bridge deck, and a first fixing mechanism is arranged on the top face of the bridge pier. After the limiting rod moves to the position above the overturned limiting wedge block, the inclined surface of the stopping block is in contact with the stopping block under the elastic force action of the spring, so that the limiting wedge block is limited through the stopping block, and the situation that the bridge deck and the limiting rod vertically move downwards due to errors when the bridge deck is lifted is prevented; when the bridge deck and the limiting rod vertically fall down, the top face of the limiting wedge makes contact with the surface of the limiting rod, the limiting wedge is attached to the stopping block, then the limiting rod is stopped, and then safety is improved.
本发明公开了一种桥梁顶升抬高时的桥梁限位装置，涉及桥梁建筑技术领域。本发明，包括桥墩和桥梁桥面，所述桥墩的顶面安装有两组顶升千斤顶，所述顶升千斤顶的顶端固定安装有顶块，且顶升千斤顶和顶块用于对桥梁桥面竖向顶升，所述桥墩的顶面设置有第一固定机构。本发明通过限位杆移动至被翻转后的限位楔块上方后，通过弹簧的弹力作用下使得阻挡块的斜面和阻挡块接触，进而使得通过阻挡块对限位楔块进行限位，防止桥梁桥面抬升时出现失误导致桥梁桥面和限位杆竖直向下移动，当桥梁桥面和限位杆竖直向下坠落时，通过限位楔块的顶面对限位杆的表面接触，通过限位楔块和阻挡块贴合进而使得对限位杆进行阻挡，进而提高安全性。
