[0003] The diamond blunt fork wing rail of this type of turnout used in the field is fixed by a base plate to the rail bottom, which plays a role in positioning the position of the rail, and prevents the rail from moving longitudinally by the friction force between the rail bottom and the base plate clamping piece; Since the train always passes through one rail in one direction, the driving wheel of the train always pushes the rail in the opposite direction of the train, and the longitudinal resistance of the fixed rail is insufficient, the rail displacement (creeping) occurs, and the position of other rail parts is dislocated, the direction change of the rail causes the train to pass through the rail, and the movable rail parts need to be moved, which causes the blockage, and the on-site maintenance cannot completely cure this disease.

[0004] The length of the turnout blunt fork wing rail currently used in the line is relatively short, and there is a large bending angle in the middle of the rail, which is a rail shared by two lines, and the movement of the rail causes the direction change of the two lines at this point, which causes the traffic to be not smooth, and the movable rail parts are blocked, and must be repaired to return to the original position, the main reason is that the displacement (creeping) of the rail caused by the insufficient longitudinal fixing force of the blunt fork wing rail.

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0023] EMBODIMENT

[0024] Referring to Figure 1 , Figure 2 A climbing blunt fork wing rail fixing structure provided by the embodiment of the present application is shown in FIG. 1, which can include: Figure 1 , Figure 2 The structure can include:

[0025] At least one set of interval iron members 1, the at least one set of interval iron members 1 are used to connect the climbing blunt fork wing rail 2 and the basic rail 3 outside, so as to increase the fixing force of the climbing blunt fork wing rail 2 and increase the longitudinal resistance of the rail;

[0026] The interval iron members 1 include two connecting rods 11 and two connecting plates 12, the two connecting rods 11 are used to connect the two connecting plates 12 to form a well-shaped member; the two connecting plates 12 are respectively used to abut the rail waist of the climbing blunt fork wing rail 2 and the basic rail 3 one by one, so as to connect the connecting plates 12 and the corresponding rails through the bolt pair 4.

[0027] Since the climbing blunt fork wing rail 2 is relatively short, the traditional way only relies on the rail bottom fixing buckle, and the fixing force is insufficient to resist the thrust caused by the train wheel passing through, so that the position of the rail moves, especially at the bending position 2 side and the movable center rail needs to be matched, when the movable center rail needs to change lanes and move, the phenomenon of blockage will appear, which causes the train to pass through not smoothly, and in serious cases, it may cause traffic accidents, therefore, the structure provided by the present application connects the climbing blunt fork wing rail 2 and the basic rail 3 outside through the interval iron, strengthens the fixing force of the blunt fork wing rail, and makes it not move.

[0028] Since the distance between the climbing blunt fork rail 2 and the basic rail 3 is not completely the same, in order to ensure that the connecting plate 12 can be in close contact with the steel rail and increase the contact area to ensure the stability of the connection, the embodiment of the present application can provide two connecting rods 11 with different lengths, so that the external contour structure formed by the two connecting plates 12 is adapted to the internal contour structure formed between the climbing blunt fork rail 2 and the basic rail 3.

[0029] In order to further improve the stability of the spacing iron member 1 after being connected with the steel rail, the embodiment of the present application can also provide that each connecting plate 12 is provided with at least two bolt through holes, so that each connecting plate 12 is connected with the corresponding steel rail by at least two sets of bolt pairs 4. The use of multiple sets of bolt pairs 4 for connection can ensure that the spacing iron will not separate from the steel rail after the railway has been in operation for a long time.

[0030] In order to further improve the close contact between the connecting plate 12 and the steel rail, the embodiment of the present application can also provide that the contour shape of the outer side surface of each connecting plate 12 is adapted to the contour shape of the rail waist of the corresponding steel rail, so that the connecting plate 12 is in close contact with the rail waist of the corresponding steel rail.

[0031] The spacing iron member 1 provided by the embodiment of the present application needs to determine the installation position on site before processing, measure the distance between the climbing blunt fork rail 2 and the basic rail 3 at the installation position, then determine the length of the connecting rod 11 and the size of the connecting plate 12 according to the actual measured size in the factory, and finally connect the connecting rod 11 and the connecting plate 12 by welding to form a cross-shaped member, and finally obtain the spacing iron member 1 by processing the bolt through hole on the connecting plate 12.

[0032] In use, the spacing iron member 1 is placed between the climbing blunt fork rail 2 and the basic rail 3 at a wider position between the climbing blunt fork rail 2 and the basic rail 3, and the spacing iron member 1 is pushed to a narrower direction until it is limited, so that the connecting plates 12 at both ends of the spacing iron member 1 are in close contact with the rail waists of the corresponding steel rails. Then, according to the position of the bolt through hole on the connecting plate 12, holes are drilled on the steel rail, and finally the installation is completed by connecting through the bolt pair 4. The entire installation process only needs to drill holes on the original railway foundation, without the need for large-scale modification of the original railway line, and the construction is simple and easy to operate.

[0033] In summary, the climbing blunt fork rail fixing structure provided by the present application increases a spacing iron between the blunt fork rail and the outer basic rail, so that the two steel rails are bound to each other, the fixing force of the wing rail is increased, the longitudinal resistance of the steel rail is increased, the blunt fork rail is no longer climbing through actual inspection, and the safe and stable operation of the train is ensured. At the same time, the structure has the advantages of low manufacturing cost, convenient installation and use, and long service life.

[0034] The embodiment of the application can also provide a compound crossing system, comprising a climbing blunt fork wing rail, a basic rail and a movable center rail; the climbing blunt fork wing rail is connected with the basic rail by using the climbing blunt fork wing rail fixing structure.
