Background
In recent years, the rapid development of rail transit brings great convenience to people, but in the field of urban rail transit, the problem of vibration noise caused by subway traffic also brings great trouble to the production and life of people. To solve such problems, various track damping measures have been developed. Particularly, in a turnout area, a vehicle transversely turns and changes lanes, the transverse impact force on the rail is large, the transverse deformation and vibration of the rail are large, and the generated rail vibration noise has great influence on surrounding buildings and residents. Particularly, as cities rapidly develop, a large number of buildings are distributed near the tracks, particularly near turnout areas, and the influence of vibration noise is more and more serious.
The improvement of shock absorption and noise reduction measures for turnout areas is imperative, and the adoption of turnout shock absorption fasteners is the mode with the fastest implementation speed and the most obvious effect according to the prior art; in the conventional damping fastener design, due to the space requirement, the overall installation height (namely the sum of the thicknesses of all parts of the fastener) of the fastener is larger and far exceeds that of the existing common turnout fastener (non-damping turnout fastener); this mismatch in mounting height will have a number of detrimental effects on the retrofit: if (1) when the installation height of the damping fastener is higher, the damping fastener needs to be excessively high compared with the existing turnout track, and because the track in the turnout area is complicated, the adjustment of a near track is also designed when one track is adjusted, so that the workload is quite large; (2) when the height adjustment amount of the track in the turnout area is large, the adjustment of a track electric power contact net is often involved, and the design has a large safety problem; (3) the great change of the installation height of the fastener is that the connection fixing mode of auxiliary facilities (such as a slide plate, a point switch, an oiler and even a snow melter) matched with a turnout area can be changed along with the change, and various devices need to be adjusted across the profession and the field, so that the difficulty is great. In order to solve the problems, the turnout damping fastener is required to be lower in installation height, can be the same as the common turnout fastener in height and has a certain damping effect.
For example, the common fastener described in publication No. CN206052470U is basically composed of an under-rail elastic cushion layer, an iron pad plate, and an under-plate elastic cushion layer, and the overall installation height of the fastener is the sum of the thicknesses of the under-rail elastic cushion layer, the iron pad plate, and the under-plate elastic cushion layer; the iron base plate and the elastic cushion layer under the plate are provided with corresponding through holes, and when the steel base plate and the elastic cushion layer under the plate are installed, the anchoring bolts sequentially penetrate through the through holes to fix the fastener on a ballast bed foundation or a sleeper. During actual operation, in order to avoid as far as possible under the board elastic cushion layer to take place obvious horizontal shear deformation under the horizontal force effect, lead to the anchor bolt to receive the shearing risk, can use very big moment of torsion to the anchor bolt usually, and then lead to under the board elastic backing plate by a large amount of compressions, make it lose most elasticity, play the elasticity cushioning effect.
