It asks and uses non-bolt spring, often occur the case where spring installation not in place or mistake installation in the construction process, cause fastener system
System can not work normally, this is also the reason of causing spring to be broken and reduce lifetime of system reduction.In addition, urban track traffic button
Part system needs have suitable gauge adjustment ability, and the mode of generally use roll adjustment buckle facilitates adjustment gauge, but in reality
In construction, often due to duration pressure and site operation proficiency's reason, lead to the installation dislocation of roll adjustment buckle, lose adjustment energy
Power simultaneously causes fastener can not work normally.
Utility model content
It is suitable for high-speed and common-speed city rail the technical problem to be solved by the utility model is to provide a kind of optimization
The fastener system of traffic installs not in place and installation excessively to be effectively prevented fastening elastic rod, prevents spring to be broken, and prevent roll adjustment
Buckle installation dislocation, so that it is guaranteed that high speed urban track traffic fastener system works normally.
Technical solution is as follows used by the utility model solves its technical problem：
A kind of fastener system suitable for high-speed and common-speed urban track traffic of optimization of the utility model, including be set to

Track gauge block, anchor bolt, double-layer spring washer and roll adjustment buckle, anchor bolt pass through iron chair on slotted hole with it is pre-buried in-orbit
The bolt sleeve on lower basis is threadedly coupled, and double-layer spring washer is set on anchor bolt and roll adjustment buckle is pressed on iron chair
On surface, spring one end is fixed in the spring jack for being set to iron chair iron portions position, and the other end is then by Insulation rail distance keeper pressure
Tightly on rail foot upper surface, it is characterized in that：The spring uses C4 springs, and limitation bullet is fixedly installed in the spring jack
The positioning block machine of insertion depth.
Gauge adjustment tooth in the laterally consecutive setting of roll adjustment buckle bottom surface upper edge transversely connects on the iron chair surface
The continuous corresponding lower gauge adjustment tooth of setting.
The utility model has the beneficial effects that efficiently solve the problems, such as that spring installation is not in place or crosses installation, it can
It effectively prevent spring to be broken, can avoid the problem of the installation of roll adjustment buckle misplaces under the construction period of high load capacity requires, increasing
Safety and reliability of the fastener system in operation, had not only facilitated construction, but also improve safety, before having wide popularization
Scape.
