The invention discloses an anti-longitudinal movement type rail fastener, which comprises a rubber backing plate II and an anti-moving iron backing plate located above the concrete short sleepers. The anti-moving iron backing plate and the short sleeper are connected by screw spikes. , There is a rubber backing plate I between the rail and the anti-moving iron backing plate, and one foot of the elastic strip is installed into the installation hole of the elastic strip of the anti-moving iron backing plate, and the other foot is pressed on the rail, outside the screw spike A nylon sleeve is installed, a stepped hole is opened at the upper part of the installation hole of the anti-moving iron pad, and the end of the large hole is a threaded hole. A threaded plug is screwed in the threaded hole. The lower end of the rod is pressed against the elastic strip. The invention has a reasonable structure design, which can not only meet the basic requirements of high-speed operation of normal railways and urban rail transit, but also prevent longitudinal sliding between the rails and the elastic bars due to vibration, and improve the running stability and safety of the train.
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...
