The specific embodiment
Embodiment 1: with reference to accompanying drawing 1-5.A kind of level is hidden wear-resisting type tongue and stock rail structure deeply, it comprises tongue and stock rail, it is characterized in that: the closely connected section horizontal slicing degree of depth of working edge of described stock rail 6mm, described tongue is with respect to the tongue of not taking this technology, and in the same position of the distance point of switch, tongue rail head width has increased 6mm, the tongue working edge is the 1:5 gradient, the inoperative limit is 1:3, reducing lateral force, thereby reaches reinforcement intensity and tongue supporting capacity.Directly in tongue rail head slicing scope, finish point of switch gauge to straight transition to standard gauge.In stock rail front end scope, finish of the transition of point of switch gauge to stock rail front tab standard gauge.Tongue adopts two shape for hat processing, and the rail height is 151mm.
Described stock rail is straight stock rail 1 or bent stock rail 3 or is straight stock rail 1 and bent stock rail 3.Described tongue is curved switch 2 or straight switch 4 or curved switch 2 and straight switch 4.
Operating principle: tongue switch relies on pulling of tongue, and train is introduced main track or lateral, and rotates flexibly, Stability Analysis of Structures, the defective that does not exist gauge to interrupt.Tongue switch mainly is made up of straight bent stock rail and straight bent tongue and union piece etc.
Rail abrasion generally can be divided into the running-in stage, stablize wear stage and the three phases that sharply weares and teares.Through after the running-in stage, profile is comparatively identical between wheel track, and the two has set up favourable relatively contact conditions, and running surface of wheeltrack is long-pending to be increased, and wheel Rail Contact Stresses descends, and rail abrasion is in the stabilization sub stage of relative mitigation.In order to improve the application life of heavy haul railway point tongue, should to prolong rail and stablize wear stage, postpone the arrival of rapid wear stage.
Causing the serious basic reason of tongue side grinding is that excessive wheel-rail force (particularly wheel-rail lateral force) causes the contact stress of tongue bigger than normal, even surpassed YIELD STRENGTH, thereby tongue friction metal covering generation plastic flow, and rolling repeatedly down at wheel load, wearing and tearing occur, peel off and fall the piece phenomenon, this is the major reason that causes rail abrasion.The wear extent of tongue all is directly proportional with load, rail stress, freight volume, is inversely proportional to the material yield limit.To effectively slow down the wearing and tearing of rail, must take engineering measure to reduce to act on load on the rail as far as possible, reduce wheel Rail Contact Stresses.Along with the increase of rail lateral force, the wheel track contact pressure on the tongue increases; Under identical load action, the tongue top width is big more, and its wheel Rail Contact Stresses is more little.Plane connection pattern to tongue and stock rail is optimized, and increases the sturdy degree of tongue in the slicing part, improves the supporting capacity of tongue.
With the shortening of tongue variable cross-section segment length, reduce apart from the maximum stress of tongue front end same distance section thereupon, particularly at the maximum stress in nearer each cross section (Yi Michu) of distance tongue front end, stress reduces particularly evident; Length of switch rail is constant, and HOMOGENEOUS BROADENING is carried out in the tongue cross section, and stressed to each cross section of tongue is favourable, and is particularly stressed for the nearer plane of weakness of distance tongue front end, and bigger help is arranged.Is that the tongue section of 40mm is widened at the tongue front end to the tread width, and the maximum stress in this section tongue cross section has significantly and reduces.
(song) stock rail directly: the processing process of stock rail: (Qu Jiben tread offset distance) → mill and hide point → assembling is transferred on blanking → sawing → number hole → boring → top.The milling depth that stock rail Tibetan apical segment 1:3 is oblique is bigger, and the rail head width will be noted the selection of survey mark, and it is smooth-going that the Tibetan apical segment mills out cutter point.Bent stock rail bending baseline is hidden on the apical segment milling face at the rail head decline 16mm 1:3 of place, and when therefore rail bent before milling, each point bending offset distance should increase 6mm.
(song) tongue directly: tongue processing process: rail head inoperative limit (1:3) → mill rail head working edge (1:5) → mill tread reduction value → planes heel end shape for hat → die mould section flaw detection → quenching → strong accent quenching distortion → timeliness → assembling is processed → milled to blanking → heel end forging and pressing → secondary stuff-assignment → sawing → mill die mould section flange of rail face → die mould section flange of rail face flaw detection → number hole → rail limb of holing → mill → mill two shape for hats of web of the rail bolt slot → tread.
Gauge is measured: because of closely connected section working edge of stock rail adopts horizontal slicing degree of depth 6mm, railway switch switch point housing section gauge is measured (comprising the point of switch) and is controlled at rail reduction value 7mm place, be convenient to on-the-spot actual measurement inspection, drawing also will mark by this measuring position.
What need understand is: though the foregoing description is to the mentality of designing of the present invention detailed text description of contrasting; but these text descriptions; just the simple text of mentality of designing of the present invention is described; rather than to the restriction of this exposed installation meter thinking; any combination, increase or modification that does not exceed mentality of designing of the present invention all falls within the scope of protection of the present invention.
