Comb-tooth-shaped bridge expansion device
The invention discloses a comb-tooth-shaped bridge expansion device which comprises a movable toothed plate installed on one beam body and a fixed toothed plate installed on the other beam body, the movable toothed plate and the fixed toothed plate are distributed in a staggered mode, a rotating mechanism used for fixing the movable toothed plate is arranged on the bottom face of the movable toothed plate, and the rotating mechanism comprises a bottom plate, a connecting plate, a rotating shaft and a rotating shaft base. The connecting plate is connected with the bottom face of the movable toothed plate, the rotating shaft is fixed to the bottom face of the connecting plate in the length direction of the connecting plate and rotationally connected with the rotating shaft base to adapt to vertical rotation of the beam body, the rotating shaft base is fixed to the bottom plate, and an elastic body adapting to horizontal rotation of the beam body is vulcanized on the side face of the rotating shaft base. The rotating mechanism is simple in overall structure, transverse, vertical and torsional deformation generated by the beam body can be met through mutual cooperation of the rotating shaft, the rotating shaft base and the elastic body, the telescopic device is not prone to damage when the beam body deforms, and driving safety is facilitated.
本发明公开了一种梳齿形桥梁伸缩装置，包括安装在一梁体上的活动齿板和安装在另一梁体上固定齿板，活动齿板与固定齿板相互交错分布，所述活动齿板底面设有用于固定活动齿板的转动机构，转动机构包括底板、连接板、转轴及转轴座，连接板与活动齿板底面连接，转轴沿连接板长度方向固定在连接板底面，转轴与转轴座转动连接以适应梁体竖向转动，转轴座固定于底板上，转轴座侧面硫化有适应梁体水平转动的弹性体。本发明的转动机构的整体结构简单，通过转轴、转轴座及弹性体的相互配合便能满足梁体产生的横向、竖向、扭转变形，使得梁体变形时伸缩装置不容易损坏，有利于行车安全。
