Self-resetting damper and anti-beam-falling damping device
The invention discloses a self-resetting damper and an anti-falling beam damping device, and relates to the technical field of bridge seismic resistance, the self-resetting damper is characterized in that a first containing cavity is formed in a fixedly arranged first cylinder barrel, and the first containing cavity is filled with a damping medium; the piston rod penetrates through the first cylinder barrel, limiting parts are arranged at the two ends of the piston rod, a damping piston is arranged on the piston rod and can be driven to move in the first containing cavity and shear the damping medium, and one end of the piston rod is connected with a to-be-damped structure; the first push rod set and the second push rod set are arranged at the two ends of the first cylinder barrel, one end extends out of the first cylinder barrel, and when the end extending out of the first cylinder barrel bears the pressure of the limiting part, the first push rod set and the second push rod set move into the first cylinder barrel. When the first push rod set and the second push rod set move into the first cylinder barrel, the pressure in the first cylinder barrel is increased, when the force applied to the first push rod set or the second push rod set is smaller than the pressure in the first cylinder barrel, the first push rod set or the second push rod set is reset, the structure is simple, and durability is high.
本发明公开了一种自复位阻尼器及防落梁阻尼装置，涉及桥梁抗震技术领域，包括固定设置的第一缸筒内设有第一容纳腔，第一容纳腔充满阻尼介质；活塞杆穿过第一缸筒，两端均设有限位部，活塞杆上设有阻尼活塞，可带动阻尼活塞在第一容纳腔中移动，剪切阻尼介质，活塞杆一端与待减震结构连接；第一顶推杆组和第二顶推杆组设置在第一缸筒的两端，且一端伸出第一缸筒外，伸出第一缸筒一端承受限位部的压力时，第一顶推杆组和第二顶推杆组向第一缸筒内移动。第一顶推杆组和第二顶推杆组向第一缸筒内移动时增大了第一缸筒内的压力，当对第一顶推杆组或第二顶推杆组的力小于第一缸筒内的压力时，第一顶推杆组或第二顶推杆组复位，结构简单，耐用性强。
