Connecting structure for maglev train rail

Abstract

The invention provides a connecting structure for a maglev train rail. The maglev train rail comprises primary F rails and secondary F rails, which are arranged alternately in sequence and connected in an end-to-end manner. The connecting structure for the maglev train rail is characterized by comprising comprises a secondary F rail connecting end face, an internal pole belly groove and an external pole belly groove which are arranged at an end part of a secondary F rail, and a primary F rail connecting end face, an internal pole belly convex platform and an external pole belly convex platform which are arranged at an end part of a primary F rail, wherein connecting holes are formed in the internal pole belly convex platform and the external pole belly convex platform, and connecting grooves matched with the connecting holes are formed in the upper parts of the internal pole belly groove and the external pole belly groove. With the adoption of the connecting structure, the primary F rail and the secondary F rail are connected firmly and can swell and shrink freely in accordance with temperature change; and the connecting structure for the maglev train rail is very simple, so that the manufacturing is convenient, and the production cost is reduced. The connecting structure for the maglev train rail is simple in connection type, easy to machine and low in cost, so that the engineering and industrialization of the maglev rail transportation system can be promoted.

Description

technical field [0001] The invention relates to a connecting structure of a rail row for a magnetic levitation train, and more particularly relates to a connecting structure of a rail row for a magnetic levitation train with simplified structure and easy processing. Background technique [0002] Maglev transportation is a brand-new transportation mode different from traditional railways, highways, and aviation. It has a series of characteristics such as low noise, small vibration, no pollution, strong line adaptability, and easy implementation. It is safe, reliable, and environmentally friendly. A new type of urban rail transit system, many cities in China have studied the use of low-speed maglev transportation technology to solve urban traffic problems. The maglev transportation project is a highly difficult and high-precision special project, and the technical performance of its track directly affects the comprehensive performance of the maglev train in operation. The ra...

Problems solved by technology

This structure makes the structure of the connection between the main F rail and the auxiliary F rail very complicated, and it is very difficult to process, which is not conducive to cost saving

[0007] However, in the above scheme, the structural connection method is complicated, the centering reset adjustment is difficult, the processing efficiency is low, there are many additional accessories, and the cost is high, which is not conducive to the systematic engineering of maglev transportation.
