Description
Technical field
The present invention relates to a kind of straddle-type screw thread self-locking track to compensate backing plate automatically.
Background technology
Rail track structure is by line（Roadbed circuit）, bridge, tunnel, station composition, the track structure of circuit is according to railway
The difference of grade and technical standard, Ballast track and non-fragment orbit can be laid.The stiffness difference of different line constructions is notable,
Train by when cause the dynamic respond of rail level inconsistent, meanwhile, the foundation settlement of different structure thing is also uneven, in transition point
Nearby easily it is deformed and causes rail level to bend.When train at a high speed by when, vehicle adds with the mutual dynamic action of circuit
Play, the serious irregularity of rail level is caused, accelerates the deterioration of line status, increases the maintenance cost of circuit, when serious even
Threaten traffic safety.
For reduce the mutation of circuit rigidity between different line constructions, it is necessary to non-fragment orbit and Ballast track, roadbed with
The junction of bridges and culverts, roadbed and tunnel and embankment and cutting sets changeover portion, to realize that circuit rigidity is gradually in the range of changeover portion
Become transition.The conventional processing method of changeover portion has：1st, in the softer side increase track vertical rigidity of changeover portion, such as using in mistake
Cross in segment limit and adjust length of sleeper and spacing to improve orbit rigidity, by using the overlength sleeper progressively increased and reduce rail
Pillow spacing can realize the progressively transition of orbit rigidity.2nd, track vertical rigidity is reduced in the harder side of changeover portion, it is general to use
The softer rubber cushion of the rail underlay of track；In the pillow big rubber cushion of underlay high resiliency；Increase railway ballast thickness on bridge, overlay railway ballast pad etc..3、
Auxiliary rail is set to improve track structure frame stiffness, auxiliary rail is made up of four rail being attached on sleeper, and two are being run
Between rail, two on the outside of operation rail.
The above method has good effect for the stiffness variation rate between reducing different line constructions, but can not solve by
Rail level caused by differential settlement bends problem between different structure, therefore has certain limitation, it is impossible to is fully solved changeover portion
Irregularity problem.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, reliable operation, can realize the straddle-type that automatic stepless is adjusted
Screw thread self-locking track compensates backing plate automatically, and it is used for the Ballast track railway roadbed of rail track structure, and it is uneven heavy to solve circuit
Irregularity problem caused by drop.
The straddle-type screw thread self-locking track of the present invention compensates backing plate, including cover plate, pedestal automatically, it is characterised in that pedestal
Upper setting positioning convex, is provided with the groove being engaged with positioning convex on cover plate, and it is cloudy that pedestal with cover plate passes through positioning convex, groove
Sun coordinates, and cover plate vertical can only be moved up and down；Driving gear is installed, between driving gear lower section and pedestal in pedestal inner chamber
Provided with plane scroll spring, the both ends of plane scroll spring are separately fixed on the bottom and pedestal of driving gear；Driving gear
Upper placement pad, be provided with equally distributed mounting hole on pad, driven gear lower end is located in mounting hole, driven gear with actively
Gear internal tooth is meshed, and the top of driven gear is connected by screw thread with cover plate, and the rotation of screw thread enables cover plate stepless-adjustment
Section；The pedestal of the outer flank of tooth of driving gear is provided with reseting gear, and reseting gear is meshed with driving gear external tooth.
The straddle-type screw thread self-locking track of the present invention compensates backing plate automatically, and pedestal is fixed by pre-embedded bolt hole and sleeper,
On railway ballast, cover plate is fixed on rail sleeper laying by pre-embedded bolt hole, and cover plate is inserted in base projection, and its work is former
Reason is the characteristic using screw thread self-locking, and by the trigger action of steel rail spring restoring force, automatic controlled height, compensating sleeper sinks
Drop amount.Concrete principle is as follows：When train wheel passes through, wheel passes through cover plate, driven gear, driving tooth to the active force of rail
Wheel, pedestal, sleeper are passed on railway roadbed, if railway roadbed settles, rail will produce elastic bending deflection downwards, work as train wheel
When leaving, the elastic deformation of rail is recovered, and produces very big upward elastic force, rail drive cover plate and driven gear together to
Upper motion, driven gear bottom is set to produce space with driving gear, now plane scroll spring drives driving gear to rotate, actively
Gear drives multiple driven gears to rotate, and screws out driven gear top screw thread, when driven gear bottom again with driving gear
Stop operating during contact, settled with this to compensate.If now railway roadbed is motionless without sedimentation, the internal gear of device；If this
When railway roadbed settle, then repeat above-mentioned regulation process.
The straddle-type screw thread self-locking track of the present invention compensates backing plate automatically, has the characteristics of simple in construction, reliable operation, it
It can realize that automatic stepless is adjusted, for the Ballast track railway roadbed of rail track structure, can solve circuit differential settlement and cause
Irregularity problem.
