Light rail large-displacement telescopic device
The invention relates to a light rail large-displacement telescopic device comprising a three-dimensional space force bearing system which is supported by a supporting system and connected to the twoends of an expansion joint through a connecting beam system. The three-dimensional space force bearing system comprises N rectangular frames of the same structure, and an inner cavity of each rectangular frame is divided into an upper square frame, a middle square frame and a lower square frame; the supporting system comprises an upper supporting system and a lower supporting system which are thesame in structure. Box bodies are located at the two ends of a cross beam and connected with the two ends of the expansion joint through connecting beam systems. The two ends of the cross beam are sleeved with inner cavities of the box bodies respectively and are in sliding connection through supports fixed to the box bodies, the N rectangular frames are evenly distributed on the cross beams between the left box body and the right box body and are in sliding connection with the cross beams through pressing supports, pressure bearing supports and side supports which are fixedly connected to inner cavities of the upper square frame and the lower square frame, and limiting systems and displacement systems are arranged in the rectangular frames. The telescopic device can meet the JT/T327-2016standard and the requirements for long single connection length, large displacement and high requirement for corner capacity of river-crossing track beams.
一种轻轨大位移量伸缩装置，包括由支撑系统支承并通过连梁系统连接在伸缩缝两端的三维空间承力系统，三维空间承力系统包括N个结构相同的矩形框架，矩形框架内腔分隔成上方框、中方框和下方框；所述支撑系统包括结构相同的上、下支撑系统，其箱体位于横梁两端并通过连梁系统与伸缩缝两端连接，横梁两端分别套在箱体的内腔并通过固定在箱体的支座滑动连接，N个矩形框架均布在左右两个箱体之间的横梁上，并通过固定连接在上下方框内腔的压紧支座、承压支座和侧支座与横梁滑动连接，矩形框架内设有限位系统和位移系统。该伸缩装置能满足JT/T327‑2016标准及“跨江轨道梁单联长度长、位移量大，对转角能力要求高”的需求。
