Displacement assembly and multidirectional displacement dustproof sliding plate expansion joint
The displacement assembly comprises displacement boxes, a cross beam and an elastic pressing device, the number of the displacement boxes is two, containing grooves are formed in the displacement boxes, the two ends of the cross beam are placed in the containing grooves of the corresponding displacement boxes, and transverse gaps are formed between the two transverse end walls of the cross beam and the transverse side walls of the corresponding containing grooves; the sum of the distance between the two transverse gaps is larger than the deformation quantity of the expansion joint, longitudinal gaps are formed between the two side walls of the cross beam and the longitudinal side walls of the containing grooves, and an elastic pressing device for pressing the top face of the cross beam is installed on the displacement box. Through the displacement assembly, the rebound energy of the dustproof sliding plate can be absorbed by the compression spring, so that the rebound strength of the dustproof sliding plate is effectively reduced, the collision strength between the dustproof sliding plate and the supporting steel plate is reduced, and the sound generated when a vehicle passes through the expansion joint is effectively reduced; the cross beam is fixedly connected with the dustproof sliding plate, the connecting bolts mainly bear transverse shearing force, the connecting bolts are not prone to loosening, and the maintenance cost is reduced.
本发明公开了一种变位组件，包括变位箱、横梁和弹性紧压装置，变位箱为两个，变位箱上开设有容置槽，横梁的两端放置在对应变位箱的容置槽内，且横梁的横向两端壁与对应容置槽的横向侧壁具有横向间隙，两横向间隙的间距之和大于伸缩缝的形变量，横梁的两侧壁与容置槽的纵向侧壁具有纵向间隙，变位箱上安装有紧压横梁顶面的弹性紧压装置，还公开了一种多向变位防尘滑板伸缩缝。通过变位组件，防尘滑板反弹的能量能够被压缩弹簧吸收，进而有效的降低了防尘滑板的反弹力度，降低了防尘滑板与支撑钢板的碰撞力度，使得车辆通过伸缩缝时的声音得到了有效降低；通过横梁与防尘滑板固接，连接螺栓则主要受横向剪力，连接螺栓则不易松动，缩减了养护成本。
