Fixed type combined frog spacing iron
The invention provides a fixed type combined frog spacing iron which comprises a spacer iron body which is of a rectangular block structure in bilateral symmetry. The spacer iron body is provided with double elliptical holes which are symmetrical left and right. The peripheries of the double elliptical holes are respectively provided with a circular positioning boss; and a middle tool withdrawal groove for separating the two double-elliptical holes is formed in the middle of the spacer iron body. The technical problems that in the prior art, a spacer iron structure is complex in manufacturing process, difficult to assemble and repair and low in production efficiency are solved. The fixed type combined frog spacing iron is stable in structure, simple in manufacturing process, high in production efficiency and high in cost performance, and the popularization and application of the fixed type combined frog in the railway turnout market are facilitated.
提供一种固定型组合辙叉间隔铁，包括间隔铁本体，间隔铁本体为左右轴对称的矩形块体结构；间隔铁本体制有左右轴对称的双椭圆孔；双椭圆孔外围分别制有圆形定位凸台；间隔铁本体中部制有将两个双椭圆孔隔开的中间退刀槽。本发明解决现有技术下间隔铁结构制造工艺复杂、组装和修配困难、生产效率低的技术问题；本发明结构稳定，制造工艺简单，生产效率较高，极具性价比，有利于固定型组合辙叉在铁路道岔市场的推广普及应用。
