AI Technical Summary

Problems solved by technology

When the train is running, the vibration of the train often causes the rails and rail buckle accessories to resonate, causing the elastic bars to slowly shift due to the vibration, which brings great safety hazards to the train operation.

Abstract

The invention discloses a fastener capable of preventing longitudinal sliding and positioning a rail. The fastener comprises a rubber tie plate II positioned above a concrete short tie and a sliding prevention iron cushioning plate, wherein the sliding prevention iron cushioning plate is in thread connection with the short tie through a screw spike, a rubber tie plate I is arranged between a steel rail and the sliding prevention iron cushioning plate, one end of an elastic strip is installed in an elastic strip installation hole of the sliding prevention iron cushioning plate, the other end of the elastic strip is arranged on the steel rail, a nylon sleeve is arranged outside the screw spike, a step hole is formed in the elastic strip installation hole of the sliding prevention iron cushioning plate, the large hole end of the step hole is a threaded hole, a thread plug is screwed in the threaded hole, an ejection rod is arranged on the thread plug through a spring in a pressing mode, and the lower end of the ejection rod is arranged on the elastic strip in a pressing mode. The fastener is reasonable in structural design, and can meet basic requirements for normal high-speed running of railway and urban railway transit, prevent longitudinal sliding caused by vibration between the steel rail and the elastic strip and improve stability and safety of trains.

Description

technical field [0001] The invention relates to a rail fastener suitable for subways, light rails or high-speed rails, specifically belonging to anti-longitudinal movement and positioning rail fasteners. Background technique [0002] With the rapid development of China's economy, the construction scale and technical level of China's railways and urban rail transit have been continuously improved, and the operating speed of railways has also increased from the original 120km / h to a maximum of 350km / h. During the construction of urban rail transit, the performance requirements of railway civil infrastructure, electrical facilities, locomotives, rails, rail fasteners, etc. are getting higher and higher. During the running of the rail transit system, vibrations are generated due to the collision between the wheels and the rails. shock. The performance requirements of rails and track fasteners are getting higher and higher, and the track fasteners have been gradually upgraded fr...
