Problems solved by technology
According to many years of operation, in order to ensure that the fasteners are not easy to loosen, the elevated rails currently used use a large nut torque to tighten the anchor bolts, resulting in the inability to provide elasticity for the height adjustment plate under the plate, which makes the overall elasticity of the fasteners poor and weakened to a certain extent. Improved vibration and noise reduction capabilities of fasteners

Embodiment Construction
[0011] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0012] Depend on figure 1 It can be seen that the present invention includes: a rail bearing plate 1; also includes: a frame base 3, a rubber bearing structure 2; 2 surround together;
[0013] The rubber bearing structure 2, the rail bearing plate 1 and the frame base 3 are vulcanized and bonded as a whole.
[0014] Depend on figure 2 It can be seen that the material of the rail bearing plate 1 and the frame base 3 in the present invention is ductile iron, which has good toughness and large bearing capacity; the rubber bearing structure 2 is rectangular, and the rubber bearing structure 2 is vulcanized and bonded to the rail bearing plate 1 and the frame base 3 as As a whole, the load is borne by the rubber bearing structure 2 under the rail bearing plate 1, the force is uniform, and the service life can be prolonged. The rubber layer 2 und...

The invention relates to a plate type damping steel rail fastener which includes a rail bearing plate (1) and also includes a framework base (3) and a rubber bearing structure (2); the rubber bearing structure (2) is arranged below the rail bearing plate (1); the framework base (3) surrounds the rail bearing plate (1) and the rubber bearing structure (2) together. The invention has the beneficial effects of being able to provide higher elasticity under the rail and the plate, being able to not only improve the working condition of the fastener, reduce the mutual actions of a wheel rail, but also prolong the service life of the fastener, improve the running stability and safety of a train, reduce the maintenance and repairing of a rail structure and have broad application prospect.
Description
technical field [0001] The invention relates to a track in the technical field of transportation, in particular to a rail fastener in the track. Background technique [0002] The rail fastener is an important part connecting the rail and the foundation under the rail. In order to maintain the good technical performance of the track structure, the rail fastener should have sufficient strength, certain buckle pressure, necessary elasticity and corresponding adjustability. For example, for PC sleepers and ballastless tracks and other rigid subrail foundations, the subrail backing plate is required to have high elasticity; for large ramp areas, fasteners are required to provide greater longitudinal resistance to prevent rails from crawling; and viaducts have no Due to the laying of seamless lines on ballast tracks, it is required that the fastening pressure should not be too large, so as to control the interaction force between the bridge deck and the rails, and prevent excessi...
