Abstract
Alloy steel reinforcement frog, be made up of heart rail, connect with the heart rail and wing rail, heart rail one end is connected with the rail that connects with the heart, and wing rail comprises left wing's rail and right flank rail, installs and be bumped into left panelling inside left wing's rail; Install inside right flank rail and be bumped into right panelling.Alloy steel reinforcement frog of the present invention, wing rail adopts the method for bending trimming to be bumped into high-strength wearable alloy-steel plate panelling, when processing steel plate, the working edge before heart rail 40 section only does chamfered edge, does not have the R13mm circular arc of rail, also will pitch heart circular arc R 13mm to reduce simultaneously, such wheel rolls across the highest abrasion position of railway frog, and railway frog contact stress will reduce, and the strength of materials improves, decrease alloy steel frog in use wing rail conquassation phenomenon, improve the application life of railway frog.
Description
Technical field
The present invention relates to railway equipment clothing arts, particularly relate to a kind of railway frog for railroad track crotch.
Background technology
Alloy steel frog is generally all laid on running speed and is no more than on the track switch of the seamless and general circuit of 250km/h transregional overlength.In recent years along with the increase of usage quantity, increasing and namely increasing currency tonnage application life is exactly the problem that pendulum is badly in need of solving in face of us.In order to reduce railway operation cost, increase economic efficiency, intend alloy steel frog and carry out process modification, the application life of common alloy steel frog can be exceeded, as proper in used, likely reach the life-span of the full-bainite steel frog of expensive one times of cost ratio alloy steel frog.
The alloy steel frog of current use is generally no more than 200,000,000 tons application life, the forging fork heart adopts wear-resisting bainitic steel difficult to understand, comparatively wear-resisting, but what its wing rail adopted is common rail manufacture, even if carry out the hard surfacing of wing rail rail head, because rail head of rail working edge exists the circular arc of 13mm, when making wheel roll across the highest abrasion position of railway frog, the developed width of wheel contact railway frog is only 25mm(wherein to contact wing rail wide for 11mm as calculated), so alloy steel frog in use wing rail conquassation phenomenon ubiquity, shorten the application life of railway frog.
Summary of the invention
Easily there is to overcome conventional alloys steel railway frog the problem that wing rail conquassation causes application life short, the invention provides a kind of alloy steel reinforcement frog of long service life.
The technical scheme that the present invention is adopted for achieving the above object is: alloy steel reinforcement frog, be made up of combination heart rail and wing rail, combination heart rail is made up of a left side connect with the heart rail and the heart rail of rail, the right side that connect with the heart, heart rail is positioned at combination heart rail end, combination heart rail is connected with interval iron between wing rail and bolt, wing rail comprises left wing's rail and right flank rail, installs left wing's rail clamping plate, be bumped into left panelling inside left wing's rail between left wing's rail and heart rail; Fill right flank rail clamping plate between right flank rail and heart rail, inside right flank rail, be bumped into right panelling.
Described left panelling and the working edge of right panelling before heart rail section are chamfer structure.
Described left panelling and right panelling are high-strength wearable alloy-steel plate.
Described left panelling, right panelling are bonding by bonding adhesive with between left wing's rail and right flank rail.
Alloy steel reinforcement frog of the present invention, wing rail adopts the method for bending trimming to be bumped into high-strength wearable alloy steel panelling, when processing steel plate, the working edge before corresponding heart rail 40mm only does chamfered edge, does not have the R13mm circular arc of rail, also will pitch heart circular arc R 13mm to reduce simultaneously, such wheel rolls across the highest abrasion position of railway frog, and railway frog contact stress will reduce, and the intensity of material improves, reduce alloy steel frog in use wing rail conquassation phenomenon of knowing clearly, improve the application life of railway frog.

Fig. 2 is the sectional drawing that railway frog strengthened by Fig. 1 medium alloy steel.
Fig. 3 be Fig. 1 medium alloy steel strengthen railway frog in heart rail 20mm sectional drawing.
Detailed description of the invention
Alloy steel reinforcement frog structure of the present invention as shown in Figure 1, be made up of combination heart rail 1 and wing rail, combination heart rail 1 is made up of a left side connect with the heart rail and the heart rail of rail, the right side that connect with the heart, heart rail is positioned at combination heart rail end, and combination heart rail 1 is connected with wing rail interval iron 10 and bolt 12, and wing rail comprises left wing's rail 3 and right flank rail 2 as shown in Figure 3, wherein a is 20mm,, left wing's rail clamping plate 7 are installed between left wing's rail 3 and heart rail, inside left wing's rail 3, are bumped into left panelling 5; Fill right flank rail clamping plate 6 between right flank rail 2 and heart rail, be bumped into right panelling 4 inside right flank rail 2, left panelling 4, right panelling 5 are bonding by bonding adhesive with between left wing rail 3 and right flank rail 2, and left panelling 5 and right panelling 4 are high-strength wearable alloy-steel plate.Installation interval iron 10 between left wing's rail 3 and right flank rail 2 and combination heart rail, left wing's rail 3 and right flank rail 2 are installed on road surface by railway frog backing plate 8, are fixedly mounted between left wing's rail 3 and right flank rail 2 by buckle 9.The horizontal section structure of wing rail as shown in Figure 2, left wing's rail 3 and right flank rail 2 two ends are fixedly installed on base 11 by bolt 12 and nut 17, bolt 12 and wing rail are installed junction and are installed track gauge block 13, bottom left wing's rail 3 and right flank rail 2, rubber mat plate 14 is installed, the bolt 12 below nut 17 is installed plain washer 16 and II type spring 15.
In order to the defect stopping alloy steel frog occurs, this alloy steel reinforcement frog continues to use the alloy steel fork heart, the method of bending trimming is then adopted to be bumped into high-strength wearable alloy steel panelling for wing rail, as shown in Figure 3, wherein a is 20mm, high-strength wearable alloy-steel plate tensile strength can reach more than 1200Mpa, and hardness reaches 360-440HB, and elongation per unit length is more than 10%.When processing steel plate, chamfered edge is only done in the panel work limit before corresponding heart rail 40mm, does not have the R13mm circular arc of rail, and also will pitch heart circular arc R 13mm simultaneously and reduce, such wheel rolls across the highest abrasion position of railway frog.The width of wheel contact railway frog is about 50mm(and wherein contacts that wing rail is wide is about 21mm), such railway frog contact stress will reduce half, and the intensity of material improves 1/3 times, substantially increases the application life of railway frog.
