Description

Railway turnout switching device

Technical field

The utility model relates to the technical field of railway turnouts, more specifically to a railway turnout switching device.

Background technique

Railway transportation is a land transportation method that uses locomotives to pull trains and vehicles on two parallel rails. The traditional method is steel wheel travel, but in a broad sense, railway transportation still includes non-steel wheel travel methods such as maglev trains, cable cars, and cableways, or rail transportation. Railroad tracks can provide an extremely smooth and hard medium for train wheels to roll on them with minimal friction, making people on them feel more comfortable, and it can also save energy. If configured properly, railway transportation can save 50% to 70% energy compared to road transportation when carrying the same weight. Moreover, the rails can evenly distribute the weight of the train, which greatly improves the load capacity of the train.

The railway grades in the era of high-speed rail are very complicated, with different angles such as road network grade, speed grade, passenger and cargo grade. The high-speed rail is higher than the National Railway Class I. Some of the National Railway Class I are express railways and some are ordinary railways. The standard track is relative to the meter gauge and the wide gauge. In the rule of thirds of the speed rating, ordinary railways are compared to express railways and high-speed railways, and in the rule of thirds, ordinary railways are compared to MRT railways.

At present, when the train is running, foreign objects often fall between the switch rail and the basic rail, which will prevent the switch from being switched and affect the normal operation of the train. At present, when the train is cleaned, it is usually manually cleaned with a broom. trouble.
