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 longitudinal leap preventing type railway fastener comprising a rubber backing plate II located on a concrete shorter tie and a leap preventing iron backing plate. The leap preventing iron backing plate and the shorter tie are connected through spiral rail spikes in a threaded mode. A rubber backing plate I is arranged between a steel rail and the leap preventing iron backing plate. One foot of each elastic strip is mounted in one corresponding elastic strip mounting hole of the leap preventing iron backing plate, and the other foot of each elastic strip is placed on the steel rail in a pressing mode. The spiral rail spikes are sleeved with nylon sleeves. A step hole is formed in the upper portion of each elastic strip mounting hole of the leap preventing iron backing plate. The large hole end of each step hole is a thread hole, each thread hole is screwed with a thread plug, pushing rods are placed on the thread plugs in a pressing mode through springs, and the lower ends of the pushing rods are placed on the springs in a pressing mode. The structure and design are reasonable. The essential requirements of normal railway operation and the high-speed operation of city rail transportation are met, and longitudinal sliding motion, produced by vibration, between the steel rail and the elastic strips can be prevented, and the stability and safety of train operation are improved.

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...
