Anti-falling rack type telescopic device
The invention relates to the technical field of bridge expansion joints, and particularly discloses an anti-falling rack type expansion device. Comprising supporting boxes, a supporting cross beam, a middle beam and rack boxes, wherein the supporting boxes are anchored to two groups of bridges and are symmetrically arranged; two ends of the supporting cross beam are respectively pre-pressed in the two groups of supporting boxes; the supporting cross beam is in rotary sliding fit with the supporting boxes; one end of each rack is installed in the rack box, the other end of each rack is used in cooperation with the top of the middle beam, the racks are arranged in parallel, and the anti-falling assemblies are located between every two adjacent racks on the same side and are in sliding fit with the two racks. The racks are arranged in a staggered mode. A tooth seam used for installing the anti-falling assembly is formed between every two adjacent racks on the same side, and one end of the anti-falling assembly is connected with the rack corresponding to the tooth seam. According to the invention, the driving is stable and comfortable, the impact load is small, and the three-dimensional deformability is good; meanwhile, safe passing of the narrow-wheel vehicle is ensured.
本发明涉及桥梁伸缩缝技术领域，具体公开了一种防陷落的齿条式伸缩装置，包括锚固于两组桥梁且对称设置的支承箱、两端分别预压在两组支承箱内且与支承箱转动滑动配合的支承横梁、套装在支承横梁外侧且滑动配合的中梁、分别安装在两组支承箱上方的齿条箱、一端安装在齿条箱内且另外一端与中梁顶部配合使用且平行设置的齿条、以及位于同侧相邻两条齿条之间且与该两条齿条滑动配合的防陷落组件；多组齿条呈交错设置；同侧相邻的两组齿条之间形成用于防陷落组件安装的齿缝，防陷落组件的一端与该齿缝对应设置的齿条连接。本发明能够使得行车平稳舒适，受冲击荷载小，具有良好的三维变形能力；同时保证窄轮车安全通行。
