The invention belongs to the technical field of railway locomotive maintenance equipment, particularly relates to a wheel reversing and positioning mechanism of a rotary trolley, and solves the problem that the wheel axis of the rotary trolley cannot be correctly positioned. The device is characterized in that a driving wheel positioning device (10) and a driving fork head mounting seat (19) are mounted on a bearing seat (11), a driving wheel tail mounting seat (16) is welded on a main beam (13), one end of a driving wheel steering driving mechanism (6) is fixed on the driving wheel tail mounting seat (16), and the other end of the driving wheel steering driving mechanism (6) is fixed on the driving fork head mounting seat (19); the electric push rod (18) can drive the bearing seat (11) to rotate by a certain angle relative to the vehicle frame, and the driving wheel positioning device (10) is matched with the spring (15), so that the wheel axis position in the running process of the traverse table is kept fixed. By means of the machining method, it is guaranteed that the wheel axis of the rotary trolley reaches the needed position precision.
本发明属于铁路机车车辆检修设备的技术领域,特别涉及一种回转移车台的车轮换向定位机构,解决回转移车台车轮轴线不能正确定位的问题。其特征是主动车轮定位装置(10)和主动叉头安装座(19)安装在轴承座(11)上,主动轮尾部安装座(16)焊接在主梁(13)上,主动车轮转向驱动机构(6)的一端固定在主动轮尾部安装座(16)上,另一端固定在主动叉头安装座(19)上,电动推杆(18)可驱动轴承座(11)相对车架回转一定角度,并通过主动车轮定位装置(10)配合弹簧(15)使得移车台运行过程的车轮轴线位置保持固定。本发明通过机械加工的方法,保证回转移车台车轮轴线达到需要的位置精度。
