Description
Technical Field
The utility model relates to a wide rail cross switch belongs to railway switch technical field.
Background
At present, the standard rail gauge of the railway in China is 1435mm, the standard rail gauge of the Russian railway is 1520mm, and wheel sets of rolling stock are manufactured according to the standard rail gauge of China. I have the Russian locomotive vehicle to pass to Russian port station, when different gauge lines cross, need set up wide standard gauge crossing switch. Due to the fact that the track gauges of the two lines are different, a certain deviation exists between the middle axis of the rhombic intersection and the center position of the obtuse frog, and therefore harmful space is increased.
Disclosure of Invention
In order to overcome the above-mentioned not enough, the utility model provides a wide rail cross switch, this wide rail cross switch can realize spacing to the wheel pair through the mode of extension obtuse frog wing rail, guarantees that the wheel pair can be through "harmful space" safely and steadily.
The utility model provides a technical scheme that its technical problem adopted is: the structure of the wide standard rail crossing turnout is as follows: the line track gauge of the upper left corner and the lower right corner is 1435mm, and the line track gauge of the lower left corner and the upper right corner is 1520 mm; the track gauge structure is widened by 5mm in the range of the obtuse frog, namely the track gauge is 1440mm, and the track gauge is 1525 mm; the two groups of acute frog are positioned on the same central line, and the theoretical tips are 13380mm apart; the two groups of obtuse frog are offset 192mm relative to the longitudinal central axis; the acute frog and the obtuse frog are connected by adopting a short steel rail; the other side of the acute frog is provided with a corresponding part with a split guard rail; rubber base plates with the thickness of 5mm are arranged between the obtuse frog and the steel rail piece and the base plates, and rubber base plates with the thickness of 10mm are arranged between the base plates and the concrete switch tie; the frog is connected with the fixed joint clamping plates on two sides of the rail web of the steel rail piece through a high-strength bolt pair; the elastic strip pressing plate is provided with a T-shaped bolt pair for buckling and pressing the steel rail on the base plate.
The utility model has the advantages that: when the wide standard gauge line is crossed, the two lines can normally drive, the structure is simple, and the maintenance is convenient.

Detailed Description
As shown in fig. 1-4, the wide rail crossing switch has the following structure:
the line track gauge of the upper left corner and the lower right corner is 1435mm, and the line track gauge of the lower left corner and the upper right corner is 1520 mm; the track gauge structure is widened by 5mm in the range of the obtuse frog, namely the track gauge is 1440mm, and the track gauge is 1525 mm; the two groups of acute frog 2 are positioned on the same central line, and the theoretical tips are 13380mm apart; the two groups of obtuse frog 1 are offset 192mm relative to the longitudinal central axis; the acute frog 2 and the obtuse frog 1 are connected by a short steel rail 3; a split guard rail 4 is arranged at the corresponding part at the other side of the acute frog 2;
a rubber base plate 8 with the thickness of 5mm is arranged between the obtuse frog 1 and the steel rail piece and the base plate 5, and a rubber base plate 9 with the thickness of 10mm is arranged between the base plate 5 and the concrete switch tie; the frog is connected with fixed joint clamping plates 10 on two sides of the rail web of the steel rail piece through high-strength bolt pairs 11; and a T-shaped bolt pair 6 is arranged on the elastic strip pressing plate 7 to buckle the steel rail on the base plate 5.
The obtuse frog 1 is a high manganese steel integral casting type fixed frog, and the acute frog 2 is correspondingly provided with a split type guard rail structure, so that the distance between the inspection interval and the back guard can be conveniently adjusted.
