Replaceable graded sliding energy dissipation self-limiting reset bridge stop block protection device
The invention provides a replaceable graded sliding energy dissipation self-limiting reset bridge stop block protection device which comprises a mounting plate, the mounting plate is detachably connected with a stop block, the stop block is arranged opposite to a main beam, a bottom plate is arranged at the bottom of the mounting plate and used for being arranged on a cover beam, and a sealing shell is arranged on the bottom plate and used for sealing the cover beam. A cushion block is arranged on the side, close to the check block, in the sealing shell, and first friction plates are arranged on the lower surface of the sealing shell and the upper surface of the bottom plate correspondingly. A second metal damper, a second connecting plate, a second viscous damper, a first connecting plate, a first viscous damper and a first metal damper are sequentially arranged between the two first friction plates and located on one side of the cushion block. According to the invention, the damage of the main beam to the stop block can be effectively prevented, the beam falling phenomenon is effectively avoided, and excellent rigidity and damping self-adaptive adjustment capability are achieved.
本发明提供的一种可更换分级滑移耗能自限位复位桥梁挡块保护装置，包括安装板，安装板与挡块可拆卸连接，挡块与主梁相对设置，安装板的底部设置有底板，底板用于设置在盖梁上，底板上设置有封壳，在封壳内靠近挡块的一侧设置有垫块，封壳的下表面和底板的上表面处均设置有第一摩擦板，在两个第一摩擦板之间且位于垫块的一侧依次设置有第二金属阻尼器、第二连接板、第二粘滞阻尼器、第一连接板、第一粘滞阻尼器和第一金属阻尼器。本发明可以有效防止主梁对挡块的破坏，有效避免落梁现象发生，具有优秀的刚度和阻尼自适应调节能力。
