Sound deadening shock absorption rail joints of coak joint staggered joints

Abstract

The invention provides a noise-elimination damping rail joint with staggered gaps connected by tenon, which is characterized in that the rail joints of the invention are connected by tenons which have different shapes and are coincident to each other; therefore, transverse broken gap of the rail joint is staggered, and the joints of two rails are mutually coincident alternatively; the wheel can pass through the joint without gap and generates no strike vibration and noise between the wheel and the rail joint gap, thus improving the comfortableness of the passenger and eliminating the harmful effect of the vibration and noise on the environment when the train passes; the rail joint with staggered gaps connected by tenon is safer, more reasonable and more stable compared with the existing butted rail joint, creates beneficial conditions for the speed-increasing of the train and is a technical breakthrough in the rail history.

Description

technical field [0001] The invention relates to the field of railway tracks, in particular to a noise-absorbing and shock-absorbing track joint with tenon-tenon joints and staggered joints. Background technique [0002] The railway track joints in the prior art generally adopt cut-off butt joints. Because the track joints of the cut-end butt joints are under the physical climate conditions of thermal expansion and contraction of objects, a gap of 3 to 5 mm will be generated in the track joints, and a track joint will be formed. A certain transverse discontinuous seam is left at the track joint. When the wheels pass by the discontinuous seam, there will be a certain impact, vibration and noise, especially when the train is running at high speed, the vibration and noise will be greater, which will cause the train to ride Passengers lose the corresponding comfort. The way the train passes, the vibration and noise produced will also have a certain impact on the surrounding envi...
