Description

Technical Field

[0001] The invention relates to the technical field of crossover design, in particular to a rail continuous turnout crossover. Background Art

[0002] Crossovers are generally composed of 4 sets of single turnouts, 1 set of diamond crossovers and connecting rails. In the design of turnouts or crossovers, it is often difficult to achieve rail continuity in the turnout frog part due to the natural harmful space of the fixed frog.

[0003] The rails in the harmful spatial position of the fixed switch are discontinuous. When the wheels pass through, the wheel-rail impact is large. The large wheel-rail impact causes damage to the wheels and the switch rails, and generates large vibration noise. Therefore, it is important to achieve the continuity of the switch rails.

[0004] In the current design, the single-turnout frog can achieve rail continuity through the design of a movable heart rail structure. However, the obtuse-angle frog and acute-angle frog in the diamond-shaped intersection part all use fixed frogs, which makes it impossible to achieve rail continuity in the entire set of crossing lines. Summary of the invention

[0005] The purpose of the present invention is to provide a rail continuous turnout crossover to improve the above problems. In order to achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] In a first aspect, the present application provides a rail continuous turnout crossover, comprising four groups of single turnouts and one group of diamond crossovers, wherein the four groups of single turnouts are connected by the diamond crossovers;

[0007] The diamond cross includes two diamond cross acute angle frogs and two diamond cross obtuse angle frogs; the two diamond cross acute angle frogs are symmetrically distributed; the two diamond cross obtuse angle frogs are symmetrically distributed;

[0008] Each of the diamond-shaped cross acute angle frogs adopts the first diamond-shaped cross acute angle frog or the second diamond-shaped cross acute angle frog;

[0009] The first rhombus cross acute angle frog comprises a first movable rail, a second movable rail, a first fixed rail, a first traction device and a first limiting device;

[0010] The second rhombus cross acute angle frog comprises a third movable rail, a fourth movable rail, a second fixed rail, a third fixed rail, a second traction device and a second limiting device;

[0011] Each of the rhombus-shaped cross obtuse-angle frogs comprises a fifth movable rail, a sixth movable rail, a fourth fixed rail, a fifth fixed rail, a third traction device and a third limiting device.

[0012] The beneficial effects of the present invention are as follows: the present invention realizes the continuity of the rails in the entire crossover area through the movable design, reducing the wheel-rail impact and vibration noise. At the same time, the movable design reduces the impact between the wheel and the rail, reduces the wheel-rail damage, and the continuous and movable rail design can also significantly reduce the vibration and noise when the train passes. In addition, the limit device is used to prevent overtravel and improve safety.
