Low-rotation-constraint hydraulic spherical hinge axial damping support
The low-rotation-constraint hydraulic spherical hinge axial damping support comprises a spherical hinge hydraulic oil cylinder, a ball head dowel bar, an oil tank, an energy storage device and a hydraulic control system, the ball head dowel bar is connected into an oil cavity of the spherical hinge hydraulic oil cylinder in a sliding mode, and the peripheral wall of a ball head of the ball head dowel bar is rotationally connected with the inner wall face of the spherical hinge hydraulic oil cylinder; one end of the oil tank is communicated with an oil cavity of the spherical hinge hydraulic oil cylinder through an oil path; the accumulator is connected with the oil tank in parallel; the hydraulic control system is arranged on the oil way to control the flow direction of hydraulic oil. A spherical hinge hydraulic oil cylinder with small rotation constraint is used as an end support of a ball dowel bar, when an earthquake occurs, the support automatically adapts to the stress and deformation requirements of the structure within the designed deformation range through a hydraulic control system, and earthquake energy is consumed; after an earthquake is finished, a new bearing capacity characteristic can be constructed by operating a hydraulic control system, so that the structure can adapt to the stress requirement under post-earthquake displacement, and the adverse effect of earthquake displacement on the structure is reduced.
本发明公开了一种低转动约束液压球铰轴向减震支座，包括球铰液压油缸、球头传力杆、油箱、储能器及液压控制系统，球头传力杆滑动连接在球铰液压油缸的油腔内且其球头的外周壁与球铰液压油缸的内壁面转动连接；油箱的一端通过油路与球铰液压油缸的油腔连通；储能器与油箱并联；液压控制系统设在油路上以控制液压油的流向。本发明利用转动约束很小的球铰液压油缸作为球头传力杆的端部支座，发生地震时，通过液压控制系统使支座在设计的变形范围内自动适应结构的受力及变形要求，消耗地震能量；地震结束后，它可以通过对液压控制系统进行操作构建新的承载力特性，利于结构适应震后位移下的受力要求和降低地震位移对结构造成的不利影响。
