Friction type damping device giving consideration to energy consumption and limiting
The invention discloses a friction type damping shock absorption device considering energy consumption and limiting. The friction type damping shock absorption device comprises a bottom plate, a fixed energy consumption plate, a movable energy consumption plate, a horizontal sliding block, an elastic element, a pin shaft and a plurality of fasteners. The bottom plate is used for being fixed to a pier, the fixed energy consumption plates are fixed to the bottom plate, and the two energy consumption plates and the horizontal sliding blocks are fixedly pressed together through the elastic elements and the pin shafts. A first friction groove is formed in the face, making contact with the horizontal sliding block, of the fixed energy consumption plate, and similarly, a second friction groove is correspondingly formed in the movable energy consumption plate. The bottom face of the first friction groove is a wedge-shaped surface composed of a first inclined face, an arc face and a second inclined face, and the first inclined face and the second inclined face are both tangent to the arc face. The second friction groove and the first friction groove have the same structure; the horizontal sliding block is provided with wedge-shaped protrusions matched with the first friction groove and the second friction groove. A good earthquake energy dissipation effect can be achieved, the main beam can be rapidly recovered to the initial position after an earthquake, and meanwhile the beam falling phenomenon can be effectively prevented through the limiting stoppers.
本发明公开一种兼顾耗能和限位的摩擦型阻尼减震装置，其包括底板、固定耗能板、活动耗能板、水平滑块、弹性元件、销轴和若干紧固件。底板用于固定在桥墩上，固定耗能板固定在底板上，两个耗能板和水平滑块通过弹性元件和销轴固定压紧在一起；固定耗能板与水平滑块相接触的面上设置第一摩擦槽，同样地，活动耗能板上对应设置第二摩擦槽；第一摩擦槽的底面为由第一斜面、圆弧面、第二斜面组成的楔形表面，且第一斜面和第二斜面均与圆弧面相切；第二摩擦槽与第一摩擦槽结构相同；水平滑块设置有与第一摩擦槽和第二摩擦槽配合的楔形突起。本发明可实现较好的地震耗能效果，并使主梁在震后快速恢复到初始位置，同时限位器也可有效防止掉梁现象产生。
