Damper device for double-layer steel truss girder arch combined system bridge
The invention relates to a damper device of a double-layer steel truss girder arch combined system bridge. The damper device comprises an oil cylinder, two ends of the oil cylinder are respectively connected with an end bridge body and a suspender, a piston is slidably connected in the oil cylinder, one end, facing the suspender, of the piston is rotatably connected with a pull rod, the pull rod extends out of the oil cylinder and is fixedly connected with an outer cylinder, and the outer cylinder slidably sleeves the oil cylinder; a plurality of circulation holes are formed in the piston and annularly and obliquely penetrate through the piston. The damping device has the beneficial effects that the piston is arranged in the damping device, the piston is rotationally connected with the pull rod, the kinetic energy of a damping medium is converted into friction heat by forming the inclined circulation hole, then energy brought by vibration is consumed, and the effect of buffering energy consumption is achieved; a plurality of circulation holes are formed in the piston, part of the circulation holes are provided with elastic pads, and the damper can automatically adjust the energy consumption effect by arranging metal sheets with different bending strengths and arranging the elastic pads which are correspondingly opened under different vibrations on the piston.
本发明涉及一种双层钢桁架梁拱组合体系桥梁的阻尼器装置，包括：油缸，油缸两端分别连接端桥体和吊杆，油缸内滑动连接有活塞，活塞朝向吊杆的一端转动连接有拉杆，拉杆伸出油缸外并固定连接有外筒，外筒滑动套接在油缸上；活塞上开设有多个流通孔，流通孔环向倾斜地贯穿活塞。本发明的有益效果是：阻尼装置内设置活塞，活塞和拉杆转动连接，并通过设置倾斜的流通孔使阻尼介质的动能转化为摩擦热，进而消耗震动带来的能量，起到缓冲耗能的作用；在活塞上设置数个流通孔，且部分流通孔设置弹性垫，通过设置不同抗弯强度的金属片，活塞上设有在不同振动下对应开启的弹性垫，使阻尼器可以自动调节耗能效果。
