Description
Technical field
The present invention relates to one and it is applicable to subway, light rail or high-speed railway rail fastener, specifically belong to anti-longitudinal leap and positioning track fastener.
Background technology
Along with the fast development of China's economic, Chinese Railway and Construction of Urban Rail Traffic scale and state of the art constantly improve, railway operation speed also brings up to the highest 350km/h by original 120km/h, along with improving constantly of operating requirement, high-speed railway and urban track traffic are more and more higher to the foundation of civil work facility of railway, the electrically performance requriements of facility, locomotive and rail, rail clip etc. while building, track traffic system, in the process of moving due to the shock of wheel and rail, produces vibratory impulse. The performance requriements of rail and rail clip is more and more higher, and rail clip is upgraded to III type, DT VI 2 type etc. gradually by I original type and II type elastic bar fastener. But these button accessories are owing to adopting e type non-bolt spring, and longitudinal stress is that frictionally makes it not produce displacement. During train operation, the vibration of train often makes rail and rail buckle accessory and produces resonance, makes spring vibrated and displacement slowly, brings very big potential safety hazard to train operation.
Summary of the invention
It is an object of the invention to the deficiency in order to make up prior art, provide a kind of anti-longitudinal leap and location type rail clip, this fastener be possible not only to the same with common III type fastener have well withhold, damping property and there is the performance of excellent anti-longitudinal leap, it is to increase the stability of train operation and security.
The present invention is achieved through the following technical solutions:
Anti-longitudinal leap type rail clip, include the rubber bearing II being positioned at above the short sleeper of concrete, anti-channeling moves iron chair, anti-channeling is dynamic adopts screw spike to be threaded between iron chair with short sleeper, it is provided with rubber bearing I between rail and the dynamic iron chair of anti-channeling, spring one pin is had to load in the dynamic iron chair spring open holes of anti-channeling, another pin is pressed on rail, nylon sleeve is installed outside screw spike, a step hole is opened on the top of the dynamic iron chair spring open holes of anti-channeling, big nose end is threaded hole, threaded plug it is screwed with in threaded hole, threaded plug is equipped with push rod by spring pressure, under push rod, side pressure is placed in spring.
Described spring afterbody has offered a ring groove, when the dynamic iron chair spring open holes of spring afterbody loading anti-channeling, blocks in ring groove after push rod automatic rebounding.
The dynamic iron chair upper surface middle portion of anti-channeling is equipped with rubber bearing I, making to contact from rigidity between rail and the dynamic iron chair of anti-channeling to turn into Elastic Contact, spring one pin loads dynamic iron chair another pin of spring open holes of anti-channeling and is pressed on rail (centre is separated by gauge pad).
The dynamic iron chair spring open holes top of described anti-channeling arranges an auto lock device, this kind of device arranges a step hole, big nose end is threaded hole, step hole is followed successively by push rod, spring and threaded plug from lower to upper, push rod stretches out hole wall under the action of the spring, and length is lower than spring inclined-plane smallest end.
Described spring afterbody increases a conical surface and conical surface rear end increases a ring groove, when the dynamic iron chair spring open holes of spring afterbody loading anti-channeling after end chamfer is pressed onto push rod, push rod bounces back, when reaching certain position, push rod card enters ring groove, prevent the buckling piece from vertically moving and accurately determining fastener position, it is to increase the safe application performance of rail fastener.
Its know-why is: the short sleeper of concrete is prefabricated with nylon sleeve, Deng sleeper reach certain intensity after the spacing that requires according to design paper set sleeper rubber bearing II, anti-channeling dynamic iron chair, rubber bearing I be installed successively, use special implement that anchoring bolt and spring are installed after the good rail of frame again, general rail can produce violent vibration in train high speed operation after installing in a manner described, even produce resonance, certain displacement can be produced, the safety that impact runs between button accessory and rail. So the ring groove of patent utilization spring afterbody of the present invention iron chair spring open holes push rod dynamic with anti-channeling coordinates its degree of freedom vertically moved of control, it is to increase the stability of track circuit and safety performance.
It is an advantage of the invention that:
Present configuration is reasonable in design, is possible not only to the basic demand that satisfied normal railway and urban track traffic run at a high speed, and is possible to prevent the wiping action that produces between rail and spring due to vibration, it is to increase train operation stability and security.
