Detailed description of the invention
Below according to drawings and Examples, this utility model is described in further detail.
With reference to Fig. 1, Fig. 2, this utility model, there is pillow shouderless elastic regardless of open type modern tram fastener, cut waiting
Being embedded with nylon sleeve 14 in the short sleeper 15 in face, double end railway spike 8 is screwed in nylon sleeve 14, the tapered section of double end railway spike 8 and
The pre-buried mutual closely connected cooperation of nylon sleeve 14 tapered section, the installing hole of nylon substrate 1 passes double end railway spike 8, is placed in short sleeper
On 15, resilient sleeper-bearing 5 under laid rail on nylon substrate 1, grooved rail 17 installs and descends on resilient sleeper-bearing 5 in-orbit, grooved rail 17 and Buddhist nun
Installing track gauge block 7 between dragon substrate 1, spring 9 is placed on nylon substrate 1, withholds track gauge block 7 by double end railway spike 8 and nut 3 solid
Determine grooved rail 17, double end railway spike 8 is installed hexagon thin nut 4, two double end railway spikes 8 are installed and is provided with plain washer 2 and is positioned at
Between nut 3 and spring 9, it is used to locking.Being bonded with flexible vibration-absorbing material at the web of the rail of grooved rail 17, fastener is overall by fastener
Cover 11 cladding, it is ensured that isolate with earth when fastener is buried.
When fastener system needs vertically to heighten, lower by descending to be encased inside between resilient sleeper-bearing 5 and nylon substrate 1 rail in-orbit
High backing plate 6, and between nylon substrate 1 and short sleeper 15, be encased inside height adjusting cushion plate 13 under plate jointly realize, when a large amount lowered by rail
During more than 20mm, spring to be configured at spring 9 and heighten seat 10, it is ensured that the using effect of spring 9, simultaneously need on fastener cover 11 times
Pad 12 heightened by configuration fastener cover, it is ensured that the installation site of fastener cover.
When fastener system needs horizontal adjustment right position, realize by changing the track gauge block of different-thickness.
Have employed the self-locking of double-deck nut, it is ensured that the spring of installation will not in use loosen, and improves fastener
Reliability.
With reference to Fig. 3, Fig. 4, fastener employs the double end railway spike of tapered section of Intermediate Gray, in use, the cone of double end railway spike
Degree section and the mutual closely connected cooperation of pre-buried nylon sleeve tapered section, strengthen the transverse strength of double end railway spike.
With reference to Fig. 5, Fig. 6, fastener can realize the 40mm amount of heightening greatly that general elastic nonseparated rail fastening is difficult to.Tool
Body method is: can be encased inside height adjusting cushion plate under the plate of the thickest 20mm under nylon substrate, descends resilient sleeper-bearing and nylon in-orbit simultaneously
It is encased inside height adjusting cushion plate under the rail of the thickest 20mm between substrate to realize.Carry out vertical direction under at rail and reach the big tune of 20mm
During high operation, descend resilient sleeper-bearing underlay to enter the orbit while lower height adjusting cushion plate in-orbit, heighten seat with the use of spring, spring is heightened
Seat, by tenon and spring mounting seat groove fit, is fixed in spring mounting seat, it is ensured that the using effect of spring.Existing
General elastic nonseparated rail fastening is owing to when rail downward a large amount reaches 10mm, having reached spring normal level and having used position
The limit, so the maximum amount of heightening is less than 10mm under its rail, the system maximum amount of heightening is less than 30mm, and this fastener overcomes this
Defect so that it is provided with wider adaptability.
