Point rail fork and rail-following matching assembly for combined frog and combined frog with point rail fork and rail-following matching assembly
The invention relates to a point rail fork and rail following matching assembly for a combined frog and the combined frog with the point rail fork and rail following matching assembly. Comprising a point rail, the point rail is provided with a central section enabling the point rail to be bilaterally symmetrical, and two grooves which are mutually symmetrical along the central section are formed in the rear section of the point rail; the two fork heel rails are symmetrically placed on the two sides of the rear section part of the point rail along the central section, and bosses attached to the grooves are arranged on the fork heel rails; the height of the upper surface of the fork heel rail is consistent with that of the upper surface of the point rail, and the edge of the upper surface of the fork heel rail extends backwards in the direction of the edge of the upper surface of the front section part of the point rail; an abutting structure is arranged between the point rail and the fork heel rail and used for preventing the point rail and the fork heel rail from being pulled open in the direction of the center section. Through the mutual abutting structure between the slopes, balance force can be formed under the influence of temperature force, so that displacement of the fork heel rail and the point rail is prevented, and the problem of bolt breakage caused by the displacement is solved.
本发明涉及一种用于组合辙叉的心轨叉跟轨配合组件及其组合辙叉。包括：心轨，心轨设置有使心轨左右对称的中心截面，在心轨的后段部设置有两条沿中心截面相互对称的凹槽；两个叉跟轨，两个叉跟轨沿中心截面相互对称地放置于心轨的后段部的两侧，叉跟轨设置有与凹槽相贴合的凸台；且叉跟轨的上表面与心轨的上表面的高度一致，叉跟轨的上表面的边缘沿着心轨的前段部的上表面的边缘的方向向后延伸；其中，心轨和叉跟轨之间设置有互抵结构，用于阻止心轨和叉跟轨沿中心截面的方向被拉开。本发明通过坡面和斜面之间的互抵结构，在受到温度力的影响的时候能够形成平衡力，从而防止叉跟轨与心轨发生位移，进而解决了由此原因发生的螺栓断裂的问题。
