Abstract
The utility model relates to a bidirection aluminum copper alloy rerailing device for a heavy load locomotive, comprising a body of a protruding arc surface structure, wherein, the body is provided with a guide edge and an iron pedal; the rerailing device is molded by the aluminum copper alloy, the guide edge of the rerailing device is designed as a circular arc guide edge which has no fixed included angle and which takes R as the radius, the R is 2700 to 2800mm; under the condition of ensuring effective intensity, the rerailing device improves the overall abrasion resistance, guarantees the safety and reliability of using the rerailing device, prolongs the service life of the rerailing device and meets the needs of modern rail locomotives.
Description
Technical field
The utility model relates to the two-way aluminum copper alloy rerailer of a kind of heavy loading locomotive.
Background technology
Two-way rerailer is a motorcycle track assisted class device, and its effect is when wheel hub that locomotive de-orbits is rolled to two-way rerailer, and the guiding rib by rerailer arcuate surface higher level guides to wheel on the rail.His principle of work is: when train wheel is rolled on the rerailer, along with the increase wheel of arcuate surface radian is elevated gradually, close to rail gradually along leading the rib direction of tilt simultaneously, when wheel rolling to the arch face vertex promptly lead rib when not holding wheel just in time be returned on the rail, finish the rerail of wheel by so simple theory of machines.Though existing two-way rerailer can satisfy the function of rail locomotive rerail on performance, but also there is defective on the structure, mainly show: former rerailer guiding rib is extended to bilateral symmetry by cambered surface summit line of centers, angle is 137 °, because the guiding rib does not have radian, in use wheel can become bigger impact to the guiding prismatic, the wearing and tearing of guiding rib have been accelerated, shortened the service life of rerailer, particularly two guide rib angles wearing and tearing especially severes, cause the guiding rib not hold and leave the right or normal track more and more far, influence the rerail effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, intensity height, the wearing and tearing that can slow down the guiding rib, the two-way aluminum copper alloy rerailer of the heavy loading locomotive that increases the service life.
The technical solution of the utility model: the two-way aluminum copper alloy rerailer of heavy loading locomotive is to transform to form on the basis of former two-way rerailer, and its inner structure and principle of work do not become, and only the guiding rib is improved; That is to say, former rerailer guiding rib is extended to bilateral symmetry by cambered surface summit line of centers that two guiding ribs that angle is 137 ° change the circular arc guiding rib that no fixed angle is radius with R into, adopt aluminum copper alloy to make rerailer, slow down the wearing and tearing life-saving.Concrete scheme: the two-way aluminum copper alloy rerailer of a kind of heavy loading locomotive, it comprises the body of arch to globoidal structure, one guiding rib is arranged on its body and step on iron, it is characterized in that described rerailer is the rerailer of aluminum copper alloy casting, the guiding rib is designed to not have fixed angle, is the circular arc guiding rib of radius with R that by two guiding branches that cambered surface summit line of centers extends to bilateral symmetry its R is 2700～2800mm on the rerailer.Design guiding rib is a circular arc guiding rib, be to consider that the actual conditions wheel in a certain moment of locomotive is to the positive pressure of the be decomposed into arc surface normal direction of guiding rib effect and the pressure of circle tangential direction, because being the angle of arc surface so horizontal applied force and cambered surface tangential direction, the guiding rib reduces gradually, therefore the object positive pressure reduces gradually, skin friction force also reduces gradually
And the former rerailer of comparing is the plane owing to the guiding rib, and its wheel does not change to the angle of guide surface application force and edge surface normal direction.Therefore wheel positive pressure size is constant, and friction force is also constant; Hence one can see that the more former two-way rerailer of the two-way aluminum copper alloy rerailer of heavy loading locomotive can effectively reduce wheel particularly guides the wearing and tearing of rib angle to the guiding rib, and wheel reduces greatly to the impact that the guiding rib causes, thereby has slowed down the wearing and tearing to the guiding rib; This shows that adopting circular arc guiding rib, this rerailer to improve the single-piece resistance to abrasion under the condition that guarantees active strength has guaranteed the safe and reliable of rerailer use, prolonged the service life of rerailer, satisfy the demand of modern rail locomotive.
Description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 is the utility model work scheme drawing.
Among the figure 1-step on the body of iron, 2-guiding rib, 3-arcuate surface.
The specific embodiment
Referring to Fig. 1, Fig. 2, the two-way aluminum copper alloy rerailer of a kind of heavy loading locomotive is constant to its overall structure of improvement and the physical dimension of original two-way rerailer, only rerailer guiding rib is improved, being about to former rerailer guiding rib 2 angles and being two guiding branches that 137 ° guiding rib extends to bilateral symmetry by cambered surface summit line of centers, to change no fixed angle into be that the circular arc of radius guides rib with R=2758mm, in order to the impact that the buffering wheel causes the guiding rib, the wearing and tearing that slow down the guiding rib.The two-way aluminum copper alloy rerailer of heavy loading locomotive is to adopt ZL205A (T5) aluminum copper alloy casting, because ZL205A (T5) aluminum copper alloy is high-ductility, high tenacity material, its high-intensity performance in the desirable strength, has also improved the periodic of rerailer in ensureing the rerailer use.Two-way rerailer after improving has improved the single-piece resistance to abrasion under the condition that guarantees active strength, improved the service life of product, has satisfied the needs of modern rail locomotive.
