[0003] The bonding method of the basic rail and the switch rail of the point switch in the prior art is the hidden tip type, and the actual tip of the switch rail is hidden within the working edge of the basic rail. The hidden tip type rail structure is suitable for the design of No. 12 and above For large-numbered turnouts on high-speed railways, for small-numbered turnouts such as No. 6 and No. 3 in urban rail transit, if a hidden-point turnout structure is used, since the basic rail and the point rail are bonded to form a bulge, the rail train will During the driving process, it is easy to cause the wheel to climb the track through the protrusion, resulting in a derailment accident

Embodiment 1
[0025] see figure 1 , the present invention provides a turnout rail structure, the turnout rail structure includes a basic rail 101 and a switch rail 102 . Specifically, the top of the base rail 101 is provided with a rail end 103 . like figure 2 As shown, the basic rail 101 also includes a rail waist 104 and a base 105, the rail end 103, the rail waist 104 and the base 105 are sequentially connected, and the rail end 103, the rail waist 104 and the base 105 are integrally formed.
[0026] One of the sides of the rail end 103 is cut to form the first cutting surface 106, and one of the sides of the rail end 103 is cut in a way that can be but not limited to planing, for example, one of the sides of the basic rail 101 is cut (The side that is about to rail end 103 needs to be bonded with point rail 102 carries out vertical slicing), certainly, in the present embodiment, the direction of slicing to rail end 103 not only can be vertical slicing, can be Slicing at any angle is...

The invention provides a turnout rail structure, which relates to the field of rail transportation. The turnout rail structure includes a basic rail and a switch rail. One side of the rail end of the basic rail is cut to form a first cutting surface, and the non-working side of the working tip of the switch rail is cut to form a second cutting surface. The surface closely fits the first cutting surface, and the size and shape of the working tip match the size and shape of the cut away portion of the end of the rail. The turnout rail structure eliminates the protruding part formed by the hidden-point turnout structure, avoids the wheel climbing caused by the protruding part of the track, and greatly reduces the probability of derailment accidents. Cutting the volume of the point rail and the point rail usually saves steel materials and production costs for mass production of basic rails and point rails.
Description
technical field [0001] The invention relates to the field of rail transportation, in particular to a turnout rail structure. Background technique [0002] Turnout is a line connection device that enables rolling stock to transfer from one track to another. It is also one of the weak links of the track and is usually laid in large numbers at stations and marshalling yards. With the turnout, the passing capacity of the line can be fully utilized. Even if it is a single-track railway, the train can be separated by laying a turnout and building a section of fork that is greater than the length of the train. Each group of turnouts is composed of a railroad switch, a switch center, two guard rails and a switch sleeper. The two movable rails are moved by the long handle with the principle of leverage, so that the wheel rim of the vehicle drives into the predetermined route according to the opening direction. . A switch is a line device that guides rolling stock to travel along t...
