The invention belongs to the technical field of special equipment repair, and relates to a repair method for an operation gnawing rail of a bridge crane cart. The repair method comprises the followingsteps: a first step of determining a gnawing rail wheel; a second step: 2.1 of allowing an overhead crane driver to start crane cart operation while a distance between the inner side surface of a wheel edge of the rail-gnawed wheel and the side surface of the rail is 8-12 millimeters; 2.2 of stopping the crane by the overhead crane driver, making another mark by a chalk on the rail while the inner side surface of the wheel edge is in contact with the side surface of the rail; a third step of jacking an end beam through a lifting jack, enabling the tread of the rail-gnawed wheel to separate from the rail, and enabling the wheel to horizontally tilt rightwards while an included angle between a center line of a wheel rolling surface and a center line of the rail is alpha in the horizontal direction, wherein the wheel and the rail horizontally tilt by an angle sigma =R*alpha. The invention provides a method for measuring a horizontal tilting angle of a large wheel. The repair method is lower in repair cost, does not need a large truck crane, and does not need a large car for transportation. The repair time is short.

    本发明属于特钟设备修理技术领域,涉及一种桥式起重机大车运行啃轨的修理方法。方法步骤如下:第一步:确定啃轨车轮。第二步:2.1让天车司机开动起重机大车运行,当发现啃轨的那只车轮的轮缘内侧面与轨道侧面间距8~12毫米时。2.2当轮缘内侧面与轨道侧面接触时,天车司机停下起重机,在轨道上用粉笔做好另一个标记。第三步:用千斤顶顶起端梁,使啃轨的那只车轮的踏面脱离轨道,当车轮滚动面中心线与轨道中心线在水平方向的夹角为α时,车轮向右水平偏斜,车轮和轨道的水平偏斜δ=R×α。本发明提供了测量计算大车轮水平偏斜角度的方法。修理费用少,不需要大型汽车吊车,不需要大型汽车运输。修理时间短。
