Abstract
The utility model discloses an elastic vibration reduction rail junction. The elastic vibration reduction rail junction comprises a steel rail, a concrete sleeper and a base plate. The base plate is fixed on the concrete sleeper through spike bolts, the steel rail is fixed on the base plate through elastic strips and bolt structures, an elastic base plate is arranged between the base plate and the concrete sleeper, and disc-shaped gaskets are arranged between the heads of the spike bolts and the base plate. Due to the vibration reduction system which is composed of the elastic base plate and the disc-shaped gaskets, vibration noise of a rail system can be lowered to be more than 8dBv, the damping effect is excellent, train traveling noise is small, train running is more stable, and thus the riding comfort of passengers is improved.
Description
Technical field
The utility model relates to track technical field, especially relates to a kind of elastic damping track switch.
Background technology
Mostly current railroad track is by iron chair, rail to be fixed on concrete sleeper, cause the train effectiveness in vibration suppression of travelling in orbit poor, noise is large, and train speed is had to certain restriction, be unfavorable for building the requirement of energy saving and environment friendly society, affect the comfortableness that passenger takes.
Utility model content
For prior art deficiency, technical problem to be solved in the utility model is to provide a kind of elastic damping track switch, to reach the object that improves track vibration-reducing effect.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of elastic damping track switch, comprise rail and concrete sleeper and backing plate, described backing plate is bolted on concrete sleeper by railway spike, described rail is fixed on backing plate by spring and bolt arrangement, between described backing plate and concrete sleeper, be provided with resilient sleeper-bearing, between the head of described railway spike bolt and backing plate, be provided with butterfly pad.
Further, described resilient sleeper-bearing is rubber mat plate.
Described backing plate is provided with the hole of passing for railway spike bolt, is provided with insulating bushing in hole, is provided with the insulation sleeve suitable with railway spike bolt in described concrete sleeper.
Described insulation sleeve is nylon sleeve.
Between described resilient sleeper-bearing and concrete sleeper, be provided with insulating pad.
The top of described insulating bushing is radially protruding.
The utility model compared with prior art, have the following advantages: more than the vibration insulating system of resilient sleeper-bearing and butterfly pad composition can make the vibration noise reduction 8dBv of track system, effectiveness in vibration suppression is good, and train vibration influence noise is little, train running is more steady, has improved the comfortableness that passenger takes.
Brief description of the drawings
Below the mark in the each width accompanying drawing of this manual expressed content and figure is briefly described:
Fig. 1 is the utility model elastic damping switch structure schematic diagram.
In figure: 1. rail, 2. track gauge block, 3. railway rail pad, 4. spring, 5. set bolt, 6. nut, 7. plain cushion, 8. railway spike bolt, 9. nylon sleeve, 10. butterfly pad, 11. insulating bushings, 12. backing plates, 13. resilient sleeper-bearings, 14. insulating pads.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, this elastic damping track switch, comprise rail 1 and concrete sleeper and backing plate 12, wherein, backing plate 12 is billet, the two ends of backing plate 12 are equipped with the hole that railway spike bolt 8 passes, and are provided with nylon sleeve 9 in concrete sleeper, matched backing plate 12 is fixed on concrete sleeper with nylon sleeve 9 by railway spike bolt 8.
Between backing plate 12 and concrete sleeper, be provided with resilient sleeper-bearing 13 and insulating pad 14, the optional rubber mat plate of resilient sleeper-bearing 13.In the hole of backing plate 12, be provided with insulating bushing 11, the top of insulating bushing 11 radially protruding formation dead ring pad, the optional rubber bushing of insulating bushing 11.
Between the head of railway spike bolt 8 and backing plate 12, be provided with butterfly pad 10, improve effectiveness in vibration suppression, and can prevent screw-down torque loose, the fastening effect of strengthening railway spike bolt 8 to backing plate.
Rail 1 is fixed on backing plate 12 by spring 4 and bolt arrangement, be specially, on backing plate 12, be fixed with two set bolts 5, rail 1 bottom is located between two set bolts 5, between rail 1 lower edge and set bolt 5, gap location is provided with track gauge block 2, and spring 4 is enclosed within on set bolt 5, by plain cushion 7 and nut 6, spring 4 is fixed up, spring adopts FOX sieve spring, improves effectiveness in vibration suppression.Between rail 1 bottom and backing plate 12, be provided with railway rail pad 3.
The vibration insulating system that resilient sleeper-bearing 13 and butterfly pad 10 form has improved the comfortableness that passenger takes more than can making the vibration noise reduction 8dBv of track system.
Form track and concrete crosstie wooden insulation shielding system by insulating bushing 11 and insulating pad 14 and nylon sleeve 9, concrete sleeper and the earth combine, thereby the insulation shielding system that forms track and the earth, prevents from affecting the signal of telecommunication in track, ensure train safe stable operation.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
