Seamless combined frog
The invention relates to a seamless combined frog which comprises a frog core, a wing rail and a frog heel rail, a frog core front section L1 and a frog core rear section L2 are provided with frog core front spacing iron and frog core rear spacing iron respectively, the frog core front spacing iron and the frog core rear spacing iron match the wing rail and the frog heel rail, and fastening and installation are achieved through a bolt pair. Compared with the prior art, the seamless combined frog has the advantages that firstly, the matching length of the wing rail and the fork core is shorter and is about 1/4 of the matching length of the prior art, and middle spacing iron and inner side clamping plates are omitted, so that the seamless combined frog is simple in structure and suitable for mass production; and secondly, main body structural components in the background technology are a point rail, the wing rail and a welding section wing rail, the center rail and the welding section wing rail are made of alloy steel, the main body components are easy-to-damage components or easy-to-lose components, the main body structural component provided by the invention is the frog core, and the frog core can be made of various materials or processes, so that the material adaptability is wider; if the main body structure loses efficacy in the service process, online interchange assembly can be achieved, the manufacturing cost is low, and the maintenance cost is low.
本发明涉及一种无缝化组合辙叉，包括叉心、翼轨、叉跟轨，所述叉心前段L1段和叉心后段L2段分别有叉心前间隔铁和叉心后间隔铁，叉心前间隔铁和叉心后间隔铁部位与翼轨、叉跟轨配合，使用螺栓副实现紧固及安装。优点：与背景技术1相比，一是本发明翼轨与叉心配合长度较短，约是背景技术配合长度的1/4，无中间隔铁、内侧夹板，因此本发明结构简单，适合大批量生产；二是背景技术主体结构部件是心轨、翼轨、焊接段翼轨，其中心轨和焊接段翼轨材质是合金钢，主体部件是易伤损部件或易失效部件，而本发明主体结构部件是叉心，叉心可选用多种材质或工艺制造，材料适应性更广，在服役过程中如果主体结构失效，可在线互换组装，制造成本低，养护成本低。
