Definitions
- the object of the present invention refers, as its title indicates, to an acute crossing of a movable railroad tip, constituting railroad apparatuses that can be incorporated into a continuous welded rail, consisting of a fixed and a mobile element, which has some important advantages over the means currently used for this purpose
- the first type of acute crossing of known moving tip encompasses those completely assembled crossings, in which the box or frame, that is, the fixed element, is of rails, preferably joined by brackets and screws to a set of plates, joined in turn to the crossbar, and the mobile element is made of machined carbon steel rails or forging elements of the same material. Also, in order to improve the wear properties in the rolling areas, different treatments have been proposed. thermal hardening of said areas
- the second type of acute crossing of known moving tip groups those crosses in which the fixed element, in its front part, is cast monobloc, preferably in austenitic manganese steel, and the mobile element is made entirely in machined rails.
- the crossings of the second type described constitute an improved design with respect to the crossings of the first type, by eliminating the assembled fixed element and replacing it with a molten monobloc box, preferably in manganese austenitic steel, and making the mobile element in machined rail
- a molten monobloc box preferably in manganese austenitic steel
- the bolted joints in the area of the fixed element subjected to the passage of the wheel are eliminated, with the consequent economy in maintenance
- This material consists of a moderate natural surface hardness (approximately 200 HBN) at the time of commissioning, in such a way that in the first moments it undergoes plastic deformations due to the passage of the wheels of the trains, which cause the typical lips and burrs on the edges of the treadboards. In fixed-point crossings, these phenomena cause maintenance work consisting of elimination. - narrate the burrs by grinding, when the cross has acquired its superficial hardness of work (approximately between 350 HBN and 400 HBN)
- the present invention relates to an acute crossing of a movable tip, suitable for coupling to entry rails and exit rails, consisting of a fixed and a mobile element, whose fixed element is constituted by a first part made in manganese cast steel and by a second part made of rails, preferably formed by the union of two rails to said first anterior part, suitable for acting as anchors to accessories such as stops, pads, ribbed plates and expansion joint, and whose mobile element is constituted by a part made of molten manganese steel and two rail parts joined to the previous one, one of said rails joining said part made in rails of said fixed element by means of bolted pads, and the other of said rails to the expansion joint, the latter part of the rail sliding longitudinally in the expansion joint on the side of the deviated line, capable of preventing the assembly formed by said mobile element from forming an indeformable triangle.
- the acute crossing of the moving tip object of the present invention has sliding means of the moving element. inside the fixed element, as well as coup
- Said rail parts, both of the fixed element and of the mobile element, which are attached to the respective parts made of molded steel to the manganese, as well as the union of the fixed molded part with the input rails, are carried out by a procedure welding, preferably by sputtering.
- the joint or joints of the molded part of the mobile element with the rail parts of said mobile element are preferably reinforced by safety flanges.
- Said molten parts of both the mobile and the fixed element can be made of carbon or low alloy steel, being heat treated, and joining the adjacent rails, that is, both the parts of both elements made in rail and the rails of entry, by conventional welding procedures
- said parts made of molten manganese steel are preferably hardened by explosion in the areas subject to wear and / or deformation by the wheels of the train, as well as in the areas of mutual coupling between said parts, up to a hardness of approximately 350 HBN
- the advantages provided by the acute crossing of the moving tip for railroad object of the present invention in its preferred construction are easily deduced, thus constituting an improvement of the two major types of existing moving tip crossing.
- the advantages provided by the use of high manganese austenitic steel in the rolling areas of both the fixed element and the mobile element by taking advantage of the material's own advantages, as it is an easily repairable material. welding, resistant to wear and shock in the most requested areas of the crossing, and in which the hard layer of the material is regenerated with the passage of the wheels, unlike materials hardened by heat treatment, whose hard layer It gradually disappears with wear and tear.
- the hardening by explosion of manganese steel in the coupling areas of the mobile element and of the fixed element, as well as in the rolling areas allows a greater life of said elements, by previously acquiring a high hardness that prevents wear and the initial plastic deformations present in the non-hardened manganese steel elements, a better preservation of the ideal geometric shape of the elements subjected to the contact of the wheel, tip and case, avoiding the formation of burrs that they can hinder the correct coupling between both, as well as noise and impacts in the rolling, and lower conservation costs, by avoiding grinding and burrs removal
- Figure 1 represents a plan view of the acute crossing of moving tip for railroad object of the present invention, giving way to the circulation by the direct line, considering that said crossing is integrated in a simple deviation with deviation to the right
- Figure 2 represents a plan view of the acute crossing of moving tip for rail represented in the previous figure, giving way to the circulation along the deviated line
- Figures 3, 4 and 5 represent the sections according to sections AB, CD and EF of Figure 1, respectively
- Figure 6 represents a plan view of the part made of manganese cast steel of the fixed element, of the acute crossing of the movable tip for railroad object of the present invention
- Figure 7 represents the section according to the section OP of the part represented in the previous figure
- Figure 8 represents a plan view of the part made of manganese molten steel of the mobile element, of the acute crossing of the moving tip for railroad object of the present invention
- Figures 9 and 10 represent the sections according to the QR and ST sections of the part represented in the previous figure, respectively
- the acute crossing of the movable railroad tip object of the present invention consists of a fixed element (1) and another movable element (2)
- the fixed element (1) is constituted by a first molded part (1A) made of manganese molten steel and a second part made of rail (1 B) formed by the union of two rails to said first molded part (1 A), and which serve as anchors for accessories such as stops, pillows, ribbed plates and expansion joint (3)
- the mobile element (2) is constituted by a first molded part (2A) of triangular shape made of molten manganese steel, and by two rail parts (2B, 2B ') joined to said molded part (2A) by its heel, through one or two extensions thereof.
- One of said rail parts (2B) is attached to said rail-made part (1 B) of said fixed element (1) by means of pads (4A, 4B, 4C) bolted together.
- said rail part (2B 1 ) of the movable element (2) slides longitudinally in the expansion joint (3), formed by the rail part (2B 1 ) and the continuation rail (5), in order to prevent the triangle formed by said mobile element (2) attached to the pads (4A, 4B, 4C) constitute an undeformable triangle when performing its lateral movement
