The invention relates to a cantilever type rotating base which comprises a fixed base assembly fixedly connected with a davit; the fixed shaft is vertically and rotationally connected with the fixed base assembly; the top, close to the fixed shaft end face, of the double-lug base is hinged to the fixed base assembly, and an adjusting block is arranged at the bottom, close to the fixed shaft end face, of the double-lug base; a kidney-shaped hole is formed in the adjusting block; the sliding block is in threaded connection with the fixed shaft, and the end part of the sliding block is in sliding connection with the kidney-shaped hole; when the fixing shaft is rotated, the adjusting block moves upwards or downwards and moves up and down along the kidney-shaped hole, and when the included angle between the double-lug base and the fixing base assembly is increased or decreased, the angle of a busbar connected with the end of the insulator is adjusted, so that the symmetrical central axis of the cross section of the busbar is perpendicular to the rail surface connecting line where the busbar is located. The whole cantilever can achieve rotation adjustment in the horizontal direction and rotation adjustment in the vertical direction, the site construction requirement is met, the pantograph-catenary matching degree is improved, train operation safety is guaranteed, and the requirement for the high speed grade of a railway vehicle is met.

    本发明是悬臂式旋转底座,包括:固定底座组件,其与吊柱固定连接;固定轴,其竖直与固定底座组件转动连接;双耳底座,其靠近固定轴端面的顶部与固定底座组件铰接,其靠近固定轴端面的底部设置有调节块;调节块上开设有腰孔;滑动块,其与固定轴螺纹连接上,其端部与腰孔滑动连接;当转动固定轴时,调节块向上或向下移动,调节块沿腰孔向上下运动,双耳底座与固定底座组件夹角增大或减小时,调整绝缘子端部连接的汇流排角度使得汇流排横断面对称中轴线垂直于所在处的轨道面连线,整个悬臂既能实现水平方向的转动调整,又能实现竖直方向的转动调整,满足现场施工要求,提高弓网匹配度,保证列车运行安全,满足轨道车辆较高的速度等级要求。
