Multi-directional moving comb plate expansion device and application thereof in bridge construction
The invention belongs to a telescopic device and application thereof, and particularly relates to application of a multidirectional moving comb plate telescopic device in bridge construction. The multidirectional moving comb plate telescopic device comprises a main toothed plate and an auxiliary toothed plate, the rear portions of the main toothed plate and the auxiliary toothed plate are arranged at beam ends or bridge abutments on the two sides of the expansion joint, working platforms located on the same horizontal plane are arranged at the beam ends or the bridge abutments below the rear portions of the main toothed plate and the auxiliary toothed plate, and a waterproof device is arranged in the expansion joint. The main toothed plate and the auxiliary toothed plate are assembled with a beam end or a bridge abutment in a sliding mode through a sliding block guide rail mechanism arranged in the transverse bridge direction, elastic media are arranged between the sliding blocks and the adjacent sliding faces of the tops of the guide rails, and elastic pads are arranged on the adjacent faces of the guide rails and the working platform. And the main toothed plate lower guide rail comprises a fixed part and a movable part which is rotationally matched above the fixed part by taking the transverse bridge direction as the axial direction. The problems that in the prior art, multi-direction movement cannot be achieved, and driving comfort is poor are solved, and the multi-direction moving device has the advantages of being capable of adapting to multi-direction movement and rotating with the transverse bridge direction as the axial direction, rapid to install and maintain, easy to achieve standardization and the like.
本发明属于伸缩装置及其应用，尤其涉及一种多向移动梳齿板伸缩装置在桥梁施工中的应用。多向移动梳齿板伸缩装置包括后部设于伸缩缝两侧的梁端或桥台上的主、副齿板，主、副齿板后部下方的梁端或桥台上设有位于同一水平面的工作平台，伸缩缝内设有防水装置；主、副齿板分别通过沿横桥向设置的滑块导轨机构与梁端或桥台滑动装配，滑块与导轨顶部相邻的滑动面之间设有弹性介质，导轨与工作平台邻接面设有弹性垫，主齿板下部导轨包括固定部以及以横桥向为轴向转动配合于固定部上方的活动部。本发明解决了现有技术存在的不能实现多向移动以及行车舒适性差等问题，具有可适应多向移动以及以横桥向为轴向转动，安装维护快捷且易于实现标准化等优点。
