Description
Technical field
The utility model is related 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, can lay Ballast track and non-fragment orbit.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 passes through at a high speed, vehicle adds with the mutual dynamic action of circuit
Play, causes the serious irregularity of rail level, accelerates the deterioration of line status, increases the maintenance cost of circuit, when serious even
Threaten traffic safety.
For reduce circuit rigidity between different line constructions mutation, 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 the interior adjustment length of sleeper of segment limit and spacing to improve orbit rigidity, by using the overlength sleeper and reduction rail that progressively increase
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 and improves track structure frame stiffness, auxiliary rail is made up of four rail being attached on sleeper, two in operation
Between rail, two on the outside of operation rail.
The above method for reducing different line constructions between stiffness variation rate there is good effect, but can not solve by
The rail level bending problem that differential settlement causes between different structure, therefore with certain limitation, it is impossible to it is fully solved changeover portion
Irregularity problem.
The content of the invention
The purpose of this utility model is just to provide a kind of simple structure, reliable operation, can realize automatic stepless regulation across
A seating screw thread self-locking track compensates backing plate automatically, and it is used for the Ballast track railway roadbed of rail track structure, solves circuit uneven
It is even to settle the irregularity problem for causing.
Straddle-type screw thread self-locking track of the present utility model compensates backing plate, including cover plate, pedestal automatically, it is characterised in that
Positioning convex is set on pedestal, the groove being engaged with positioning convex is provided with cover plate, pedestal and cover plate are by positioning convex, recessed
Groove negative and positive coordinate, and cover plate vertical can only be moved up and down；Driving gear, driving gear lower section and pedestal are installed in pedestal inner chamber
Between be provided with plane scroll spring, the two ends of plane scroll spring are separately fixed on the bottom and pedestal of driving gear；Actively
Pad is placed on gear, equally distributed mounting hole is provided with pad, driven gear lower end is located in mounting hole, driven gear with
Driving 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 nothing
Level regulation；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.
Straddle-type screw thread self-locking track of the present utility model compensates backing plate automatically, and pedestal is consolidated by pre-embedded bolt hole with sleeper
Fixed, on railway ballast, cover plate is fixed on rail sleeper laying by pre-embedded bolt hole, and cover plate is inserted in base projection, its work
It is using the characteristic of screw thread self-locking, by the trigger action of steel rail spring restoring force, automatic controlled height, compensating sleeper as principle
Settling amount.Concrete principle is as follows：When train wheel passes through, wheel passes through cover plate, driven gear, active to the active force of rail
Gear, pedestal, sleeper are passed on railway roadbed, if sedimentation occurs in railway roadbed, rail will downwards produce elastic bending deflection, when train car
When wheel leaves, the elastic deformation of rail is recovered, and produces very big upward elastic force, and rail drives cover plate and driven gear together
Motion upwards, makes driven gear bottom produce space with driving gear, and now plane scroll spring drives driving gear to rotate, main
Moving gear drives multiple driven gears to rotate, and screws out driven gear top screw thread, when driven gear bottom again with driving tooth
Stopped operating during wheel contact, sedimentation is compensated with this.If now railway roadbed is without sedimentation, the internal gear of device is motionless；If
Now there is sedimentation in railway roadbed, then repeat above-mentioned regulation process.
Straddle-type screw thread self-locking track of the present utility model compensates backing plate automatically, the spy with simple structure, reliable operation
Point, it can realize that automatic stepless is adjusted, for the Ballast track railway roadbed of rail track structure, it is possible to resolve circuit differential settlement
The irregularity problem for causing.
