Utility model content
The technical problems to be solved in the utility model is to provide and a kind ofly can improves the simple turnout of train-side to Negotiation speed, also provides a kind of train-side that can improve to No. 7 simple turnouts of Negotiation speed, No. 8 simple turnouts, No. 9 simple turnouts.
In order to solve the problems of the technologies described above, simple turnout of the present utility model, comprises one group of fixed curve railway frog; Described fixed curve railway frog comprises two radical center rails, and be straight line for the straight heart rail to passing through, the heart rail current for side direction is curve; The described heart rail radius current for side direction is identical with lead curve rail radius.
No. 7 simple turnouts of the present utility model, comprise one group of fixed curve railway frog; Described fixed curve railway frog comprises two radical center rails, and be straight line for the straight heart rail to passing through, the heart rail current for side direction is curve; The described heart rail radius current for side direction is identical with lead curve rail radius, and radius is 160-200m.
Described No. 7 simple turnout rail specifications are 43 or 50 or 60kg/m.
The heart rail radius that described No. 7 simple turnouts are used for side direction current is identical with lead curve rail radius, and radius is 180m.
No. 8 simple turnouts of the present utility model, comprise one group of fixed curve railway frog; Described fixed curve railway frog comprises two radical center rails, and be straight line for the straight heart rail to passing through, the heart rail current for side direction is curve; The described heart rail radius current for side direction is identical with lead curve rail radius, and radius is 180-220m.
Described No. 8 simple turnout rail specifications are 43 or 50 or 60kg/m.
The heart rail radius that described No. 8 simple turnouts are used for side direction current is identical with lead curve rail radius, and radius is 210m.
No. 9 simple turnouts of the present utility model, comprise one group of fixed curve railway frog; Described fixed curve railway frog comprises two radical center rails, and be straight line for the straight heart rail to passing through, the heart rail current for side direction is curve; The described heart rail radius current for side direction is identical with lead curve rail radius, and radius is 270-330m.
Described No. 9 simple turnout rail specifications are 43 or 50 or 60kg/m.
The heart rail radius that described No. 9 simple turnouts are used for side direction current is identical with lead curve rail radius, and radius is 300m.
Adopt structure of the present utility model, due to fixed curve railway frog be used for directly to current heart rail be straight line, the heart rail current for side direction is curve, the heart rail radius that side direction is current is identical with lead curve rail radius, so just be equivalent to the length extending lead curve rail, thus just can improve radius of lead curve under the condition on field wire road, existing station, to improve train-side to Negotiation speed, improve conevying efficiency.Adopt structure of the present utility model, radius of lead curve can increase 20-70%, and track switch can improve 20-50% laterally through speed, as No. 7 simple turnout radiuses can be increased to 160-200m, can bring up to more than 30km/h laterally through speed; No. 8 simple turnout radiuses can be increased to 180-220m, can bring up to more than 35km/h laterally through speed; No. 9 simple turnout radiuses can be increased to 270-330m, can bring up to more than 45km/h laterally through speed.
Adopt structure of the present utility model, fully can excavate the potential of field, existing station, circuit, do not need to expand track switch place, train-side can be improved to greatest extent to Negotiation speed, improve conevying efficiency, save a large amount of construction funds and field, station land used.The utility model structure is simple, and easily manufactured, cost is low, can be widely used in railway and be particularly useful for metro construction.
