The specific embodiment
The utility model proposes a kind of heavy haul railway track intensifying device; Be preferably designed for the 75kg/m rail that is applicable to Qun Dynasty's railway and use the plain edition rail brace; This plain edition rail brace has been strengthened the lateral stiffness of rail in sharp radius curve and long steep grade highway section; Improve the overturning or slip resistance analysis performance and horizontal drag of rail, reduced rail wear speed; Further describe as follows below in conjunction with the concrete structure of accompanying drawing this plain edition rail brace:
The structure of this plain edition rail brace 1 comprises base plane 10, vertical plane 11 and in the both sides of said base plane 10 respectively and two side elevations 12 of 11 settings of vertical plane; It is characterized in that: said base plane 10 1 ends upwards are provided with a boss 13 and stretch out and form an extended surface 14; The height of the height of said boss 13 and the rail flange of rail 9 is complementary, and this extended surface 14 is complementary with the upper surface of the rail flange of rail 9; Said extended surface 14 is connected with said vertical plane 11, and said vertical plane 11 is complementary with the rail web of the rail 8, at the contact surface of said vertical plane 11 with the rail web of the rail 8; The groove 16 that the other end setting of said base plane 10 is upturned; The end of the upper surface of said groove 16 and spring 4 is complementary; And be provided with two groove catch 15 at the back side of this groove 16, be used for nylon apron block 6 is fixed between two groove catch 15; Have rectangular through hole 17 on the said base plane 10, bolt 5 runs through and is arranged in the said through hole 17.
Wherein, 75kg/m rail height is 192mm, and the rail head height is 55.3mm, and in order to make rail brace and rail coupling, the height of the vertical plane 11 of this rail brace 1 can not surpass 136mm.Consider train through the time rail 2 receive the lateral force of pointing to the rail outside flare take place; The high rim of rail head and rail brace will keep certain distance; When guaranteeing the stressed flare of rail head of rail, rail head can not run into the top edge of rail brace, thereby has guaranteed the ride comfort of circuit; The stress distribution law of the web of the rail during according to the stressed flare of rail, the vertical plane 11 suitable height of this rail brace 1 are between 90mm～120mm; Simultaneously; The width of this rail brace 1 receives the restriction of width and 4 pairs of limb width of spring of sleeper 3; Spring is withheld in the rectangular groove of the extended surface of rail brace and rail brace end; Width between two side elevation 12 inwalls of this rail brace 1 will guarantee that spring 4 can put into wherein; And make the gap between spring 4 and two side elevations 12 not excessive, prevent spring 4 install and use in significantly shift phenomenon takes place, the width range between said two side elevation 12 inwalls suits between 140mm～200mm; The thickness of said two side elevations 12 is wanted to guarantee that this rail brace 1 has enough intensity; Can the lateral force that vertical plane 11 bears be passed to the groove 16 of front end through two side elevations 12; And power is finally passed to sleeper 3 through the nylon apron block 6 under the groove, therefore the thickness of said two side elevations 12 suits between 8mm～15mm; The form of circular arc chamfering 18 need be made in the junction of said two side elevations 12 and groove 16; Produce stress when avoiding rail 2 stressed flares that lateral force is passed to this rail brace 1 concentrates and then crackle takes place herein in the junction; Thereby influence the intensity of this rail brace 1; Wherein, the radius of circular arc chamfering 18 should not be less than 5mm; In order to make the radius size and spring 4 radiuses of groove 16 mate each other, guarantee that the front end of spring 4 can be put into groove 16 simultaneously, the radius of groove 16 should be greater than the radius of spring 4, and the radius of its further groove 16 suits between 12mm～18mm.
This plain edition rail brace 1 is arranged between rail 2 and the sleeper 3; Through spring 4 and bolt 5 said rail brace 1 is fixed; Further also be provided with the nylon apron block 6 between sleeper 3 and this rail brace 1 front end; Also be provided with rubber mat plate 7 between the bottom of rail 2 and the sleeper 3, can mate well between the rail brace 1 that adopts above-mentioned set-up mode to make to have said structure and rail 2 and the sleeper 3, also further reduced the lateral displacement of rail head of rail simultaneously; The rectangular through hole 17 that has on the said base plane 10 makes bolt 5 run through and sets within it that spring 4 fixes through bolt 5 and nut and rail brace 1; Set up the groove 16 that closely contacts with nylon apron block 6 along base plane 10 front edges; Spring 4 withhold upper surface and the rectangular groove 16 that a little is positioned at boss 13; The back side of groove 16 is provided with two groove catch 15; Be used for nylon apron block 6 is fixed between two groove catch 15, prevent train through the time said nylon apron block 6 rush outside stressed.
Above-mentioned rail brace fastener is installed the back and is compared with existing II type elastic bar fastener, and when not having train to pass through, flare does not take place rail 2, and rail 2 stresses are consistent with gauge apron; When train through the time, about the equal outside flares of two strands of rail 2, the gage elastically widened amount increases, the rail web of the rail 8 contacts with rail brace 1, lateral force is born on rail brace 1 top.The rail brace 1 that use has a said structure does not change the stressed rule of fastener, has just reduced the stress of rail 2, has improved the safety stock of rail 2.Above-mentioned rail brace structure analyzed show that this rail brace 1 can significantly improve rail torsional property and horizontal limit drag, use this rail brace 1 back track structure torsional property to improve about 40%, maximum transverse force is brought up to about 15t.The use of this rail brace 1 can reduce rail stress, inboard gauge apron stress, rubber mat plate compressive stress and rail head of rail lateral displacement; Not only can adapt to the heavy haul railway track structure; And rail brace 1 has enough intensity, can play the supplemental support effect to rail 2.
At the heavy haul railway rail the described track intensifying device of the utility model is installed; Under the acting in conjunction of parts such as rail brace 1, spring 4 and bolt 5, make rail 2 and sleeper 3 tightly be fixed together, reduced the excessive lateral displacement of rail head of rail; Make gauge and line style keep good; Can effectively suppress the track structure distortion, strengthen track stability, improve the track irregularity state.
In a word; The track intensifying device that the utility model provides has been realized good track strengthening effect after installing and using, particularly rail flare amount obviously reduces; It is good that the gauge line style keeps; Track side abrasion reduces, and has greatly reduced routine servicing maintenance works amount, has certain popularization value and use value.
