Embodiment Construction
[0021] Figure 1~Figure 6 Among them, there is an integral rectangular sleeper plate 1 in the vertically intersecting four-corner track of the track, and vertically intersecting rails 2 and 3 are connected to the top of the sleeper plate. At the vertically intersecting rails, the inner side of the rail in one direction 4 is adjacent to the other square rail. Between the ends 5 there is a narrow slit 6 that matches the thickness of the convex rim of the track wheel, and a shuttle-shaped pad is embedded in the slit, and the shuttle-shaped pads in the two directions perpendicular to each other have an overall shuttle-shaped Spacer 7 and the combined shuttle-shaped spacer 8 formed by two pieces, the shuttle-shaped spacer has a trapezoidal top 9, the distance b from the upper plane on the trapezoid to the top of the rail head, the radius of the track wheel rim and the track wheel The difference between the radii of the wheel faces is equal.

A perpendicularly crossing four-angle rail assembly comprises an integrated rectangular sleeper slab. Perpendicularly crossing rails are connected to the upper surface of the sleeper slab. Slits matched with thicknesses of convex-shaped rims of rail wheels are reserved between inner sides of the rails in one direction and adjacent ends of the rails in the other direction. Fusiform blocks are embedded in the narrow slits within trapezoid upper surface sections. The distance between an upper plane of each fusiform block and an upper surface of a head of each steel rail head equals to a difference between the radius of the rim of each rail wheel and the radius of a wheel surface of the rail wheel. Load of a rail car passing through the perpendicularly crossing rails can be evenly and effectively dispersed by the integrated rectangular sleeper slab. When the rail wheels pass through the slits, outer circumference of the rim of each rail wheel can be guided to roll on the upper plane of each fusiform block by the fusiform blocks, so that in a transient period of the rail wheel passing through the slits, subsidence and vibration are avoided, and the rail wheel cannot be stuck in the slits and can run normally.
Description
technical field [0001] The invention relates to a rail at the vertical crossing of the rails, in particular to a rail at the vertical crossing of the rails and a spacer on the rail crossing slit. Background technique [0002] The track has two parallel steel rails. There are sleepers under the rails. The sleepers and the track are vertically and evenly arranged under the rails. The sleepers are used to maintain the gauge and direction of the rails. The rail is a long profile with an I-shaped section. The upper part of the rail has a rail head, and the lower part of the rail has a rail bottom. There is a rail waist between the rail head and the rail bottom. Provide a continuous, smooth surface and guide the wheels to run. The rail bears the load of the rail car. The outer circumference of the rail wheel has a cylindrical wheel surface that matches the top of the rail head. In order to prevent the rail wheel from derailing, especially when turning , There is a convex rim on t...
