Damping bridge expansion device
The invention discloses a damping bridge expansion device, which relates to the technical field of bridge expansion devices, and comprises a seam crossing toothed plate, a fixed toothed plate and a damper, one end of the seam crossing toothed plate is used for being connected with one end of a beam end gap of a bridge, and one end of the fixed toothed plate is used for being connected with the other end of the beam end gap of the bridge; the other end of the seam crossing toothed plate is a first toothed plate, and the other end of the fixed toothed plate is a second toothed plate; the first toothed plate is matched with the second toothed plate; a damper is arranged at one end of the seam-crossing toothed plate; a damper is arranged at one end of the fixed toothed plate; and a damper is arranged at the other end of the seam crossing toothed plate. The requirement for arbitrary displacement of the beam end can be met, and the anchoring part slowly compresses the elastic-plastic body in the cavity so that movement and rotation in all directions can be achieved. The shock absorption and noise reduction functions can be achieved, impact of a vehicle mainly acts on the cross-seam toothed plate, at the moment, the speed lock plays a role and becomes a rigid component to resist the impact effect, after impact, the toothed plate continuously vibrates, the damper becomes a flexible component, damping is increased, and vibration and noise are reduced.
本发明公开一种阻尼桥梁伸缩装置，涉及桥梁伸缩装置技术领域，包括跨缝齿板、固定齿板和阻尼器；跨缝齿板的一端用于与桥梁的梁端间隙的一端相连接，固定齿板的一端用于与桥梁的梁端间隙的另一端相连接；跨缝齿板的另一端为第一齿板，固定齿板的另一端为第二齿板；第一齿板与第二齿板相匹配；跨缝齿板的一端设有阻尼器；固定齿板的一端设有阻尼器；跨缝齿板的另一端设有阻尼器。可实现梁端任意变位要求，锚固件在腔体内缓慢压缩弹塑性体以实现各方向的移动及转动。能够实现减振降噪功能，车辆的冲击主要作用于跨缝齿板，此时速度锁定其发挥作用，变成刚性构件抵抗冲击作用，冲击后，齿板持续振动，阻尼器变成柔性构件，增加阻尼降低振动及噪音。
