Multi-directional displacement combined type bridge expansion device
The invention relates to the field of bridge expansion devices, in particular to a multidirectional displacement combined type bridge expansion device. The telescopic device comprises a comb plate (1) and a telescopic mechanism fixed below the comb plate (1), the telescopic mechanism is fixedly connected with an embedded structure in the bridge end, the telescopic mechanism comprises two symmetrically-arranged displacement boxes (5), and the displacement boxes are connected with the two ends of a supporting cross beam (9) in an overlapped mode. The device further comprises a shaft type displacement body (2), the shaft type displacement body (2) comprises a rotating shaft in the middle and an elastic rubber body arranged around the rotating shaft, the shaft type displacement body (2) penetrates through the supporting cross beam (9), the upper end and the lower end of the shaft type displacement body (2) are both located in the sliding clamping groove and can slide in the sliding clamping groove, and the sliding clamping groove is a groove in the inner wall of the displacement box (5). Connecting plates (6) are arranged on the outer sides of the two displacement boxes (5), and limiting springs (7) connected through the connecting plates (6) are further included.
本发明涉及桥梁伸缩装置领域，尤其涉及一种多向变位组合式桥梁伸缩装置。该伸缩装置包含包括梳齿板（1）及固定在其下方的伸缩机构，伸缩机构与桥梁梁端中的预埋结构固定连接，伸缩机构包含两个对称布置的位移箱（5），位移箱搭接着支撑横梁（9）的两端；还包含轴型变位体（2），轴型变位体（2）包含中部的转动轴以及围绕转动轴布置的弹性胶体，该轴型变位体（2）穿过支撑横梁（9），轴型变位体（2）的上端和下端均位于滑动卡槽中并能够在滑动卡槽中滑动，滑动卡槽为位移箱（5）内壁上的槽。在两个位移箱（5）的外侧上布置有连接板（6），还包含通过连接板（6）连接起来的限位弹簧（7）。
