Reinforced multi-directional displacement expansion device
The invention relates to the field of bridge expansion devices, in particular to a reinforced multi-directional displacement expansion device. The device is characterized in that two boundary beams and more than one middle beam between the two boundary beams are arranged above a gear type bridge expansion device; one side of each boundary beam is divided into an upper water stop belt clamping groove and a lower water stop belt clamping groove through a middle structure, the middle structure is of a splayed-like structure, and the splayed-like structure comprises a protrusion inclining upwardsand a protrusion inclining downwards; the edges of a water stop belt can be inserted into the water stop belt clamping grooves; splayed-like structures are also arranged on the two sides of each middle beam; and the gear type bridge expansion device comprises a supporting beam and displacement boxes on the two sides, one or more gears (409) are installed on the supporting beam (7), the two sides of the supporting beam (7) are located in the displacement boxes (404), racks (407) are fixed in the displacement boxes (404), and when the expansion device stretches out and draws back, the racks andthe gears slide in an engaged mode in the proper sliding process of the supporting beam (7), and sliding resistance can be enhanced.
本发明涉及桥梁伸缩装置领域，尤其涉及一种加强型多向变位伸缩装置，齿轮式桥梁伸缩装置上方包含两个边梁以及两个边梁之间一个以上的中梁；边梁一侧通过中部结构分为上下两个止水带卡槽，该中部结构为类八字结构，该类八字结构包含一个倾斜朝上一个倾斜朝下的凸起；止水带的边沿能够插入止水带卡槽中；中梁两侧也包含类八字结构；齿轮式桥梁伸缩装置包含支撑横梁和两侧的位移箱，支撑横梁（7）上安装着一个以上的齿轮（409），支撑横梁（7）的两侧位于位移箱（404）中，在位移箱（404）中固定有齿条（407），当伸缩装置进行伸缩的时候，支撑横梁（7）适当滑动的过程中，齿条和齿轮啮合滑动，能够增大滑动阻力。
