Description
Technical field
The utility model is related to a kind of fixing device of railroad track, is specifically a kind of anti-creep folder of track concrete pillow
Tool.
Background technology
Humping track is the principal character of marshaling yard, and it is build on the ground small just as camel peak antiform shape
Massif, is designed to the gradient adapted to, places an iron railway above, auxiliary using the potential energy produced by the gravity of vehicle and the gradient of hump
Carry out a kind of marshalling facilities of spliting up a train with locomotive thrust, be also marshalling yard's spliting up a train and the main method organized into groups again.When
Train is in running on ramp, and it has the effect of a longitudinal force with rail, mainly frictional force, and rail can be made to produce longitudinal direction and moved
Position, even drives rail to move together, this phenomenon is called " creeprail " sometimes.The humping track designed in vehicle marshalling station
For continuous grade, ruling grade is up to 44 ‰, and smallest curve radius is 180m, continuously across S-curve during humping of cars, to circuit
Impact is very big, easily causes rail from being creeped under slope on slope.When rail creeping amount reaches 20mm, to ensure the row of equipment
Car safety, must just carry out drawing the even seam corrective maintenance processing of rail, not only influence the scheduling of marshalling yard's train, but also expend a large amount of
Manpower and materials.
The content of the invention
The purpose of this utility model is just to provide a kind of track concrete pillow anti-creep fixture, is organized into groups with the sacurity dispatching for solving train
With the crawling problemses for preventing track from occurring again.
Scheme of the present utility model includes rail, concrete pillow, anti-creep fixture, vertical spacing adjusting screw and crosswise joint spacing
Screw rod, it, which is structurally characterized in that on the downside of rail, is sequentially provided with front and rear concrete pillow, before and after the left and right sides of rail is respectively equipped with successively
Two anti-creep fixtures, the upper end of anti-creep fixture is provided with neck, and the front and rear sides of anti-creep fixture are provided with vertical screw, vertical screw
Equipped with vertical spacing adjusting screw, the left and right sides of anti-creep fixture, which is provided with horizontal screw, horizontal screw, to be provided between crosswise joint
Away from screw rod, the bottom of rail is provided with base, and anti-creep fixture is installed on the base of rail by neck, vertical spacing adjusting screw
Rear and front end is attached separately in the vertical screw of former and later two anti-creep fixtures, and the inboard leading screw of anti-creep fixture is provided with fixed spiral shell
Mother, the outside of anti-creep fixture is provided with cushion pad, and cushion pad is provided with positioning convex groove, and anti-creep fixture is recessed provided with positioning accordingly
Groove, the left and right ends of crosswise joint spacing screw rod are separately mounted in the horizontal screw of anti-creep fixture, crosswise joint spacing screw rod
Outer end be provided with clamp nut.In the two ends of described vertical spacing adjusting screw, wherein one end is set to anti-silk, when rotation adjustment
During leading screw, the anti-creep fixture at leading screw two ends can outwardly or inwardly stretch simultaneously.During installation, correction position is by before and after anti-creep fixture
Two ends are rested the head on respectively against in former and later two concretes, and have padded cushion pad, rotate adjusting screw, anti-creep fixture is held out against and rested the head in concrete
On, locked with fixing nut, then the clamp nut of crosswise joint spacing screw rod outer end is locked, i.e., rail is fixed as with concrete pillow
One.
The utility model is simple in construction, reasonable in design, after anti-creep fixture is installed, and can be integrated rail with concrete pillow locking,
The frictional resistance for making the longitudinal direction of rail creep all passes to concrete pillow, and concrete is rested the head on keeps stable under the lateral resistance effect of railway roadbed,
Be effectively controlled telescopic moving of the rail caused by under the change driven a vehicle and expanded with heat and contract with cold, it is ensured that rail joint rail gap it is steady
It is fixed, the workload of routine servicing is reduced, equipment safety risk is reduced, the utilization rate of track circuit is improved.
It is described in further detail below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is left anti-creep fixture scheme of installation；
Fig. 2 is anti-creep fixture front view；
Fig. 3 is the utility model structural representation.
