Longitudinal displacement and vertical rotation comb-tooth-shaped expansion device for bridge
The invention discloses a longitudinal displacement and vertical rotation comb-tooth-shaped expansion device for a bridge. The device is characterized in that a movable comb plate and a fixed comb plate are respectively arranged between a main bridge body and an approach bridge body of the bridge, and deformation of the main bridge body generated along the longitudinal direction relative to the approach bridge body is accommodated through the longitudinal movement between the movable comb plate and the fixed comb plate; the movable comb plate swings around the horizontal roller shaft relative to the fixed comb plate to accommodate the deformation of the main bridge body in the vertical direction relative to the approach bridge body. The device has the functions of longitudinal displacement and vertical rotation, and in addition, the horizontal roll shafts and the anchored rubber supports are mutually independent, do not interfere with each other and have the function of adapting to two-way displacement. The device has the advantages of simple structure, convenience in processing and manufacturing and easiness in matching.
本发明公开了一种纵向变位和竖向转动的桥梁用梳齿形伸缩装置。特点是将活动梳齿板与固定梳齿板分别设置于桥梁的主桥体与引桥体之间，通过活动梳齿板及固定梳齿板相互之间的纵向移动容纳主桥体相对于引桥体沿纵向产生的变形；通过活动梳齿板绕水平辊轴相对于固定梳齿板的摆动容纳主桥体相对于引桥体沿垂直方向产生的变形。本发明具有纵向变位和竖向转动的功能，此外，本发明的水平辊轴与锚压的橡胶支座相互之间具有独立地、互不干扰且适应双向变位的功能。本发明具有结构简单、加工制作方便，易于配套的优点。
