Fig. 1 is a schematic view of the whole structure of the dislocation type double-limb elastic bendable frog of the present invention.
In the figure: 1-a first wing rail, 2-a second wing rail, 3-a long center rail, 4-a short center rail and 5-a fixed base.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the present invention provides a technical solution: the staggered double-limb elastically bendable frog comprises a first wing rail 1, a second wing rail 2, a long point rail 3 and a short point rail 4.
First wing rail 1 and second wing rail 2 are symmetrical or asymmetric setting, are provided with a long heart rail 3 and a short heart rail 4 between first wing rail 1 and the second wing rail 2, and the one end fixed connection of long heart rail 3 weak point 4's one end.
In this embodiment, the first wing rail 1 and the second wing rail 2 have a waist portion bent relatively, and the joint of the long center rail 3 and the short center rail 4 is located between the waist portions of the first wing rail 1 and the second wing rail 2, both the long center rail 3 and the short center rail 4 can be bent and moved, and the reliable operation of the double-limb elastic bendable structure is realized by the mutual dislocation of the long center rail 3 and the short center rail 4 in the conversion process. The long core rail 3 and the short core rail 4 are of a continuous structure and are not provided with inclined joints.
Furthermore, one end of the long point rail 3 and one end of the short point rail 4 form a triangular structure together.
In this embodiment, the end portions of the long point rail 3 and the short point rail 4 of the triangular structure are located in the middle between the waist portions of the first wing rail 1 and the second wing rail 2, and the long point rail 3 and the short point rail 4 are respectively parallel to the two wing rails, when a station track in a certain direction is to be opened, the frog point rail is closely attached to the wing rail in the same opening direction and is separated from the other wing rail, so that the harmful space of the common turnout does not exist. Practice proves that the turnout harmful space is eliminated, the running is more stable, and the structural vibration is reduced, so that the turnout is particularly suitable for urban rail transit with high running density and high environmental protection requirements.
Further, long rail 3 and short rail 4 are formed integrally by a coupling member.
In the present embodiment, the long rail 3 and the short rail 4 integrally formed by the coupling member are structurally stable and safe to use.
Furthermore, the first wing rail 1, the second wing rail 2, the long point rail 3 and the short point rail 4 are all made of materials the same as those of the common steel rail.
In the embodiment, the first wing rail 1, the second wing rail 2, the long point rail 3 and the short point rail 4 are made of the same material as that of a common steel rail, and the wing rails and the point rails can be welded with the front steel rail and the rear steel rail of the frog, so that the design of a turnout seamless track is realized, and the turnout seamless track is safe to use.
Further, the bottom of first wing rail 1 and second wing rail 2 is provided with a plurality of unable adjustment base 5, and unable adjustment base 5 fixed connection first wing rail 1 and second wing rail 2, and unable adjustment base 5 swing joint long heart rail 3 and short heart rail 4.
In this embodiment, the fixing base 5 is rectangular plate-shaped and is sequentially arranged in parallel at intervals, the fixing base 5 is a steel base plate, and the antifriction coatings are arranged between the long point rail 3 and the short point rail 4 and the fixing base 5, so that the friction coefficient of the rail bottom of the point rail can be reduced, and further the friction force is reduced.
The utility model discloses a theory of operation and use flow: the utility model discloses install the back, when will opening a certain direction thigh way, frog point rail just with open the wing rail of direction unanimity and closely paste, separately with another wing rail, so, the harmful space of ordinary frog has just not been survived. Because the utility model discloses not set up the scarf, the straight side of train passes through the frog homoenergetic and guarantees that the trajectory is continuous, does not have the gap. Practice proves that the railway vehicle eliminates the harmful space of the frog and the inclined joint, the travelling is more stable, and the structural vibration is reduced, so that the railway vehicle is particularly suitable for urban rail transit with high travelling density and high environmental protection requirements. The long center rail 2 and the short center rail 3 in the conversion process are staggered with each other, reliable work of a double-limb elastic bendable structure is achieved, harmful space and an inclined joint can be eliminated, meanwhile, good linear control of a turnout is achieved, the structural design is simplified, the stability of a train is improved, driving conditions are improved, vibration noise generated by wheel rail impact is reduced, and the requirement for environmental protection is met.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
