Alloy steel frog
The invention belongs to the field of rail transit, and relates to an alloy steel frog. The alloy steel frog comprises wing rails, a point rail, a fork heel and spacer irons, the wing rails are arranged on the two sides of the point rail, the fork heel is arranged on the rear portion of the point rail, the spacer irons are arranged between the wing rails and the point rail, clamping grooves are formed in the rear portion of the fork heel, and the fork heel spacer irons are installed in the clamping grooves. The alloy steel frog is simple in structure; the fork heel is connected with the pointrail through welding, during casting, and the point rail and the fork heel are directly cast together, so the manufacturing cost is low, and the improvement difficulty is small; the overall frog adopts alloy steel as a raw material, so the frog has high strength, good toughness, long service life and low wear rate; the fork heel is obtained through special design, so the tolerance intensity duringpassing of heavy vehicles is ensured, the service life is prolonged, and the reliability is improved; and the wing rails are 5-7 mm higher than the point rail, so that the stability of running vehicles is improved, the vehicles can pass through the frog at a high speed, the requirement for railway acceleration is met, the running efficiency is improved, and the running cost is reduced.
本发明属于轨道交通领域，涉及一种合金钢辙叉。包括翼轨、心轨、叉跟和间隔铁，翼轨设置在心轨两侧，心轨后部设置有叉跟，翼轨与心轨之间设置有若干间隔铁，叉跟后部设置有若干卡槽，卡槽内安装有若干叉跟间隔铁。本发明结构简单，叉跟与心轨通过焊接连接，在铸造时直接将心轨和叉跟铸造在一起，制造成本低，改进难度低，整体采用合金钢作为原材料，强度高，韧性好，使用寿命长，磨损率低，叉跟通过特殊设计，保证了重型机车通过时的耐受强度，提高了使用寿命，提高了可靠性，将翼轨的高度高于心轨的高度5mm‑7mm，提高了运行车辆的稳定性，可以以一个较高的速度通过辙叉，达到了铁路提速的要求，提高了运行效率，降低运行成本。
