A kind of rail fastener system of stable connection, the rail foot are provided with hollow gasbag.
A kind of rail fastener system of stable connection, the air bag include parallel portion and positioned at parallel portion two sides
Vertical component effect, for the vertical component effect perpendicular to the parallel portion, the length of the parallel portion is consistent with rail foot length；It is described vertical
It is provided with inflating port in portion, is provided with sealing cover at the inflating port.
A kind of rail fastener system of stable connection is provided with sealing ring at the sealing cover.
A kind of rail fastener system of stable connection, first plate and the second plate are integrally formed.
The utility model it is achieved the utility model has the advantages that
The fastener system of the utility model using fixing rail with the web of the rail the first plate disposed in parallel, meanwhile, pass through company
It connects block to be fixedly connected with the second plate, rail is fixed on sleeper, structure is simple, and it is i.e. mountable only need to be screwed into a screw, behaviour
Make quick.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, rail, 2, sleeper, the 3, first plate, the 4, second plate, 5, pedestal, 6, link block, the 7, first threaded hole, 8,
Second threaded hole, the 9, first screw, 10, support rod, 11, parallel portion, 12, vertical component effect, 13, inflating port, 14, sealing cover, 15, close
Seal, 16, third threaded hole, the 17, second screw.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As shown, a kind of rail fastener system of stable connection of the utility model, including rail 1, it is located under rail 1
Side sleeper 2 and fastener, the fastener include with 1 web of the rail of rail the first plate 3 disposed in parallel, first plate 3 be connected with
Vertically disposed second plate 4 of first plate 3；Further include the pedestal 5 positioned at 1 bottom of rail, be provided with link block 6 on the pedestal 5,
The first threaded hole 7 is provided on the link block 6, corresponding position is provided with the second threaded hole 8 on second plate 4, and one first
Screw 9 is screwed into the first threaded hole 7 after passing through second threaded hole 8 again.
Further, it is additionally provided with support rod 10 on the pedestal 1, is installed with third screw thread on the support rod 10
Hole 16, one second screw 17 pass through 16 hole of third screw thread against the first plate 3.First plate 13 is consolidated by the second screw 17
It is fixed, fixed effect is further increased, the second screw 17 can not also be used and the first plate 3 is carried out using other fixed links
It is fixed.
Further, the rail foot is provided with hollow gasbag.Rail 1 is subtracted by inflated airbag
Shake, good damping effect.
Specifically, the air bag includes parallel portion 11 and the vertical component effect 12 positioned at 11 two sides of parallel portion, the vertical component effect 12
Perpendicular to the parallel portion 11, the length of the parallel portion 11 is consistent with 1 bottom lengths of rail；It is provided on the vertical component effect 12
Inflating port 13 is provided with sealing cover 14 at the inflating port 13.
When in use, air bag is laid on sleeper 2 first, is inflated from inflating port 13 to air bag, vertical component effect 12 fills
After gas erects, steel rail laying 1, continuing to be inflated to the distance between vertical component effect 12 and rail 1 is within 5mm, then complete
At installation.
The horizontal and vertical movement of rail 1 is buffered respectively by vertical component effect 12 and parallel portion 11, meanwhile, vertical component effect
12 can also limit the transverse shifting of rail 1, thus stronger fixation rail 1.
Further, it is provided with sealing ring 15 at the sealing cover 14, improves the sealing performance at sealing cover 14, guarantees
Air bag is air tight.
Further, first plate 3 and the second plate 4 are integrally formed.Integrally formed first plate 3 and the second plate 4 connect
It connects more stable.
The fastener system of the utility model when in use, is screwed into again after passing through second threaded hole 8 by the first screw 9
Second plate 4 is fixed on link block 6 by the first threaded hole 7, so that rail 1 is fixed on sleeper 2.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
