The invention is suitable for the technical field of rail transit, and provides a rail transit ultralow clearance contact net supporting device which comprises a supporting beam assembly, one end of the supporting beam assembly is installed on a lifting base through a supporting mechanism, and the lifting base is fixedly installed on a stand column; the other end of the supporting beam assembly is provided with a guide wheel used for supporting the overhead line system. When the supporting mechanism does not need to be adjusted, a limiting pin abuts against the interior of a limiting clamping groove, the effect of limiting rotation of a supporting gear is achieved, meanwhile, a limiting toothed rod abuts against the interior of a limiting toothed ring, the effect of limiting rotation of a lead screw is achieved, and the stability of the whole structure of the supporting mechanism when the supporting mechanism is not used is guaranteed; by adjusting the position of the movable tooth holder, the elevation angle of the supporting beam assembly is changed, and the requirement for multi-angle installation of the rigid suspension type contact net is met.
本发明适用于轨道交通技术领域,提供了一种轨道交通超低净空接触网支撑装置,包括支撑梁组件,所述支撑梁组件的一端通过支撑机构安装在升降座上,所述升降座固定安装在立柱上;所述支撑梁组件的另一端设置有用于对接触网进行支撑的导向轮。本发明的支撑机构在不需要进行调节操作时,限位销抵在限位卡槽内,起到限制支撑齿轮旋转的效果,且与此同时,限位齿杆抵在限位齿环内,起到限制丝杆旋转的效果,保证了支撑机构整体结构在不使用时的稳定性;本发明通过调整移动齿座的位置,进而使得支撑梁组件的仰角发生变化,满足刚性悬挂式接触网的多角度安装。
