Wheel structure and steel rail grinding wagon
The invention provides a wheel structure and a steel rail grinding wagon, relates to the field of railway tracks, and solves the problem that when the steel rail grinding wagon grinds a turnout curved strand, the rim of a guide wheel collides and even damages the actual tip end (hereinafter referred to as a frog tip) of a frog point rail. The wheel structure comprises a wheel body, wherein the wheel body is provided with a tread and a rim which are connected, the top of the rim is provided with an inclined part, the inclined part is located on the outer side of the rim, and the portion, which is connected with the root of the rim, of the inclined part gradually inclines in the direction away from the tread in the radial direction of the wheel body, so that the inclined part and the middle lower part of the frog tip extrude each other when passing through the frog tip so as to provide guide force for steering of the wheel body. The inclined part is arranged on the top of the rim and arranged on the outer side of the rim, a large gap is formed between the wheel and the frog center before initial contact, the hidden danger of collision when the wheel initially makes contact with the frog center is eliminated, the inclined part of the rim and the lower middle part of the frog tip extrude each other to provide gentle guide force for steering of the small wheel, and the rim of the steel rail grinding wagon is prevented from colliding with the frog tip.
本发明提供了一种车轮结构及钢轨打磨车，涉及铁路轨道领域，解决了钢轨打磨车在打磨道岔曲股时，导向轮轮缘会撞伤甚至撞坏辙叉心轨实际尖端（以下简称叉尖）的问题。该车轮结构包括轮体，轮体具有相连接的踏面和轮缘，轮缘顶部存在有倾斜部，且倾斜部位于轮缘的外侧，且倾斜部与轮缘根部连接的部位沿轮体的径向逐渐向背离踏面的方向倾斜，以在经过叉尖时与叉尖中下部相互挤压为轮体转向提供导向力。本发明在轮缘顶部上设置倾斜部，且倾斜部设置在轮缘外侧，车轮与叉心在初始时接触前有较大的间隙，消除车轮初始接触叉心时的撞击隐患，轮缘的倾斜部与叉尖中下部相互挤压为小车轮的转向提供较为缓和的导向力，防止钢轨打磨车轮缘碰撞叉尖。
