The invention belongs to the technical field of seat platforms, and discloses a rotary platform for a railway vehicle. The rotary platform comprises a rotary motor, a pinion, a gearwheel, a translation motor and a platform bottom plate, the gearwheel and the pinion are meshed with each other, the rotary motor drives the pinion to move, the pinion drives the outside of the gearwheel to rotate, andthe translation motor is connected with the right side of a rotary driving plate. Driving gears are symmetrically installed on the front side and the rear side of the rotary driving plate, and drivingsliding blocks are installed below the rotary driving plate. Outer racks and inner racks are symmetrically installed on the front side and the rear side of the platform bottom plate, the outer racksare fixed to the partition sliding rails, sliding blocks on the front side and the rear side of the platform bottom plate are installed in the partition sliding rails in a sliding mode, the inner racks are fixed to the platform bottom plate, and the driving gear is meshed between the outer racks and the inner racks. The moving distance of the partition sliding rail is twice that of the rotary driving plate. Automatic reversing of the seat is achieved, when the control system breaks down, seat reversing can be conducted manually, and good application prospects are achieved.

    本发明属于座椅地台技术领域,公开了一种轨道车辆用旋转地台,包括旋转电机、小齿轮、大齿轮、平移电机、地台底板,大齿轮和小齿轮互相啮合,旋转电机带动小齿轮运动,小齿轮带动大齿轮外部旋转,平移电机和旋转驱动板右侧相连,旋转驱动板前后两侧对称安装有驱动齿轮,旋转驱动板下方安装有驱动滑块;地台底板前后两侧对称安装有外齿条和内齿条,外齿条固定在隔断滑轨上,地台底板前后两侧的滑块滑动安装在隔断滑轨中,内齿条固定在地台底板上,驱动齿轮啮合在外齿条和内齿条之间,隔断滑轨移动的距离是旋转驱动板移动距离的两倍。本发明实现了座椅的自动换向,控制系统出现故障时,可人工进行座椅换向,有着很好的应用前景。
