Background

With the rapid development of rail transit, more and more urban rail transit lines are laid in the modes of overhead lines, ground lines and the like, and more lines penetrate residential areas and areas with dense personnel. However, when the vehicle is running, the rail vibration is increased due to the impact between the wheels and the rail, and the noise radiation generated thereby affects the normal life of people. In addition, the vibration of the steel rail is increased, so that the impact force between the wheels and the steel rail is increased, the defects of wavy abrasion of the steel rail and the like are caused, and the maintenance workload and the maintenance cost of the track line are greatly increased.

The damping vibration-damping noise-reducing device is arranged on the steel rail to reduce the vibration and noise radiation of the steel rail and relieve the corrugation of the steel rail, which is one of the currently adopted methods. The damping vibration-damping noise-reducing device arranged on the steel rail is usually adhered to the steel rail by an adhesive, and the adhesion mode needs to polish the steel rail, which is labor-consuming and time-consuming; when the adhesive is used outdoors, the aging resistance, the water resistance, the low temperature resistance and the high temperature resistance of the adhesive are tested seriously, the adhesive is easy to age and loses the bonding performance, so that the vibration-damping and noise-reducing device falls off; in addition, the bonding mode is difficult to remove and recover, and the maintenance cost is greatly increased when the track is overhauled.

The buckling ends 31 extend towards both sides (i.e. along the length direction of the steel rail 1) to form a T-shaped structure, so as to increase the buckling area of the buckling plate 3, thereby further improving the stability of buckling.

In an exemplary embodiment, as shown in fig. 2 to 4, two ends of the connecting plate 2 are provided with shoulder structures 21, the shoulder structures 21 are provided with first through holes 22, the crimping plate 3 is provided with second through holes 32, and the fastening members 4 pass through the first through holes 22 and the second through holes 32. The diameter of the second through hole 32 is larger than the diameter of the fastening member 4 to allow a displacement of the holding-down plate 3 toward the rail 1.

The buckling plate 3 is connected with the connecting plate 2 in a mode that a fastening piece 4 penetrates through the connecting plate. The fastening member 4 may be a bolt or a screw, and is fastened by a nut after passing through the first through hole 22 and the second through hole 32. The torque through control bolt can adjust the dynamics that cramp plate 3 compresses tightly connecting plate 2. Of course, the first through hole 22 may also be partially disposed on the shoulder structure 21 and partially disposed at the bottom of the connection plate 2; alternatively, the first through-hole 22 is provided entirely in the bottom of the connection plate 2 (instead of being provided on the shoulder structure 21).

In an exemplary embodiment, as shown in fig. 2 to 4, the contact surface between the shoulder structure 21 and the crimping plate 3 is an inclined surface, and when the fastening member 4 fastens the crimping plate 3 and the connecting plate 2, the crimping plate 3 approaches the rail damping vibration and noise reducer 8 along the inclined surface.

The contact surface between the shoulder structure 21 and the buckling plate 3 is an inclined surface, and the connecting plate 2 and the buckling plate 3 are fixed through the fastening piece 4, so that the relative sliding between the connecting plate 2 and the buckling plate 3 can be prevented. The fastening plate 3 can be close to or far from the steel rail 1 in a small range by adjusting the torque of the bolt, so that the pressing force of the fastening plate 3 on the steel rail damping vibration attenuation noise reducer 8 is adjusted. Moreover, the contact surface is set to be an inclined surface, so that the outward deviation of the buckling plate 3 can be effectively prevented.

In an exemplary embodiment, as shown in fig. 2 and 7, a buffer insulation layer 5 is provided between the tie plate 2 and the rail 1.

The number of the anti-rotation structures 23 is 2, and the anti-rotation structures are respectively correspondingly connected with the fasteners 4 (bolts) of the two buckling plates 3.

In an exemplary embodiment, as shown in fig. 2, an insulator 7 is disposed between the crimping end 31 and the rail damping vibration and noise reducer 8.
