Description

U-shaped fastening split pin for railway

Technical Field

The utility model relates to a split pin technical field, specific railway is with U type fastening split pin that says so.

Background

Railways are track lines on which vehicles such as trains run. The explanation of the term "thesaurus" for railways is: locomotive traction vehicles are used for forming a train (or a vehicle with a power device of the locomotive) and a traffic line running on a regular basis. Railway transportation is a type of land transportation in which a locomotive pulls a train vehicle over two parallel rails. The traditional mode is steel wheel traveling, but the generalized railway transportation still includes non-steel wheel traveling modes such as magnetic suspension trains, cable cars, cableways and the like, or rail transportation. The rails provide an extremely smooth and hard medium on which the train wheels roll with minimal friction, making the upper person more comfortable, and it also saves energy. If properly configured, rail transport can save five to seven costs of energy over road transport when carrying the same weight. Moreover, the rails can evenly disperse the weight of the train, so that the loading capacity of the train is greatly improved.

Because the existing fastening split pin for the railway has the advantages of single structure, poor stability, low installation flexibility and inconvenience for use. Therefore, we propose a U-shaped fastening cotter pin for railways to overcome the above problems.
