Abstract
The utility model discloses a kind of high speed railway track strengthening rail brace, the structure of this rail brace comprises back elevation, base plane, and two side elevations arranged between described base plane both sides are respectively at back elevation, be characterized in: described base plane front end is provided with a downward boss, the other end upwards extends to form extended surface, this extended surface is connected with back elevation, and base plane central authorities are provided with a rectangular through-hole; And described back elevation central authorities are provided with a rectangular through hole, the stove bolt that its size uses with installation matches.Rail brace and rail can be fixed with stove bolt by the utility model further, make forces acted on rail reasonable, reduce the rail head of rail lateral deformation because train Lateral Force causes, train operation stability is improved, improve train by time track dynamic irregularity, and reduce track side abrasion; And the utility model structure is simple, be convenient to processing, installs and uses very convenient, can avoid producing the practical problems such as component loss, rapid wear.
Description
Technical field
The utility model relates to a kind of railway track accessory, is specially the intensifying device of high-speed railway railroad track.
Background technology
In track component, in order to anti-wheel-rail lateral force effectively, the parts installed outside rail.Rail brace is generally arranged on the outside of track with small-radius curve foreign stock rail, and during to prevent train by curve, excessive lateral force causes track lateral displacement excessive, even causes the overturning of rail.
High-speed railway, as a kind of new transportation mode of modern society, has the clear superiorities such as speed is fast, safe, energy-conservation.Speed is the main mark of high-speed rail technology level, each state is all improving constantly the speed of service of train, and the highest operation speed per hour of France, Japan, Germany, Spain and Italian bullet train reaches 300 kilometers, 300 kilometers, 280 kilometers, 270 kilometers and 250 kilometers respectively.This high speed travels, and the lateral force that rail is born at switch section and curve section is larger, and gauge and linear being difficult to keep, and side wear is serious, and maintenance workload is very large.Now, the effect of rail brace is more outstanding, and the stuctures and properties for rail brace is had higher requirement.
Summary of the invention
The purpose of this utility model is the problems referred to above existed to solve prior art, provides a kind of high speed railway track to strengthen rail brace, to promote the stability of railway track, guarantees safety, simultaneously convenient for maintaining.
Technical solution of the present utility model is: a kind of high speed railway track strengthening rail brace, the structure of this rail brace comprises back elevation, base plane, and two side elevations arranged between described base plane both sides are respectively at back elevation, be characterized in: described base plane front end is provided with a downward boss, the other end upwards extends to form extended surface, this extended surface is connected with back elevation, and base plane central authorities are provided with a rectangular through-hole; Described back elevation central authorities are provided with a rectangular through hole, and the stove bolt that its size uses with installation matches.
Further, above-mentioned high speed railway track strengthening rail brace, wherein: the contact surface of described back elevation and steel rail web matches, described base plane and the contact surface at the bottom of Rail match, and described extended surface and the connection curved surface between steel rail web and the flange of rail match.
Further, above-mentioned high speed railway track strengthening rail brace, wherein: the size of the rectangular through-hole in described base plane is greater than the cross section of erection bolt and is less than the coverage rate of the spring that installation uses.
Technique effect of the present utility model is mainly reflected in:
(1) rail brace and rail can be fixed with stove bolt by the utility model high speed railway track strengthening rail brace further, make forces acted on rail reasonable, decrease the rail head of rail lateral deformation because train Lateral Force causes, train operation stability is improved, improve train by time track dynamic irregularity, reduce track side abrasion;
(2) rail brace structure of the present utility model simple, be convenient to processing, install and use very convenient, can avoid producing the practical problems such as component loss, rapid wear.

In figure, the implication of each Reference numeral is: 1-rail brace, 2-rail, the 3-web of the rail, the 4-flange of rail, 5-spring, 6-bolt, 7-sleeper, 8-stove bolt, 11-back elevation, 12-side elevation, 13-boss, 14-base plane, the rectangular through hole of 15-, 16-rectangular through-hole, 17-extended surface.
Detailed description of the invention
The intensifying device of a kind of railroad track that the utility model proposes, is preferably applicable to high-speed railway.This high speed railway track strengthening rail brace strengthens the lateral stiffness of rail in sharp radius curve, track switch and long steep grade section, improves the overturning or slip resistance analysis performance of rail.
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, is easier to make technical solutions of the utility model understand and grasp.
With reference to figure 1, Fig. 2, Fig. 3 and Fig. 4, two side elevations 12 that the structure of rail brace 1 described in the utility model comprises back elevation 11, base plane 14 and arranges between described base plane 14 both sides are respectively at back elevation 11, wherein back elevation 11 matches with the contact surface of steel rail web 3, base plane 14 with 4 to match at the bottom of Rail; Described base plane 14 front end is provided with a downward boss 13, and its height matches with height at the bottom of Rail; Described base plane 14 other end upwards extends to form extended surface 17, and this extended surface 17 is connected with back elevation, and and connection curved surface between the flange of rail 4 of rail and the web of the rail 3 match; Described base plane 14 central authorities are provided with rectangular through-hole 16, and the size of this through hole is greater than the cross section of bolt 6, is less than the coverage rate of spring 5; Described back elevation central authorities are provided with a rectangular through hole 15, and its size and stove bolt 8 match.
As Fig. 4, this rail brace 1 is arranged between rail 2 and sleeper 7, bolt 6 runs through spring 5 and rectangular through-hole 16 is arranged in rail brace, the base plane 14 of rail brace is made to be fixed on the contact surface of at the bottom of Rail 4, run through the back elevation 11 of rail 2 and described rail brace in addition again with stove bolt 8, make rail brace back elevation 11 and steel rail web 3 close contact.Adopt this set-up mode can make to have the rail brace 1 of said structure can mate better with between rail 2 and sleeper 7, simultaneously, stove bolt 8 is adopted rail brace 1 and the further of rail 2 to be fixed, make rail 2 reasonable stress, decrease the rail head of rail lateral deformation because train Lateral Force causes, train operation stability is improved, improve train by time track dynamic irregularity, reduce track side abrasion.
Certainly, be more than representative instance of the present utility model, in addition, the utility model can also have other multiple detailed description of the invention, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the claimed scope of the utility model.
