Description

Technical Field

[0001] This utility model belongs to the technical field of rail transit, specifically a single-opening turnout alloy steel composite frog. Background Technology

[0002] The combined frog of a single turnout is a hybrid structure that integrates the advantages of fixed frogs and movable frogs. The wing rails and frogs of the fixed frog ensure lateral stability during passage, while the movable frog in the straight track area eliminates harmful space and improves the smoothness of high-speed train passage. Its design balances economy and performance, reducing the high cost of fully movable frogs while minimizing the impact and vibration of fixed frogs. It is suitable for lines with mixed passenger and freight traffic or low siding traffic.

[0003] Patent document CN114000381B describes a single-opening turnout with embedded wing rail type alloy steel combined frog, including a stabilizing system, a first deflecting part, a second deflecting part, and a converging part. The first deflecting part and the second deflecting part are located at both ends of the converging part. The first deflecting part, the second deflecting part, and the converging part are coaxial. The cross center lines of the first deflecting part and the cross center lines of the second deflecting part are deflected radially relative to the converging part. The converging part is a track structure that converges towards the center. The stabilizing system fixes the first deflecting part, the second deflecting part, and the converging part to the ground. The deflection direction of the first deflecting part and the second deflecting part is both towards the frog axis.

[0004] Existing combination forks have certain shortcomings in use. Combination forks mainly consist of wing rails, frog rails, and guard rails. When passing laterally, the wheels are guided by the wing rails and frog rails that are fixed to the fork. The end of the frog rail is a pointed structure, and the wheel first contacts the tip of the frog rail when changing rails. The end structure of the frog rail cannot be replaced, and wear will occur after long-term use, affecting the safety of vehicle operation. Secondly, the sides of the wing rails, frog rails, and guard rails have a certain angle. During installation, the fixing device needs to be adjusted according to the installation angle of the wing rails, frog rails, and guard rails, which makes it impossible to complete the installation operation quickly. Utility Model Content

[0005] This utility model provides a single-opening alloy steel composite frog, which can solve the problem in the prior art where the end of the frog rail is a pointed structure. When the wheel changes rails, it first comes into contact with the pointed end of the frog rail. The end structure of the frog rail cannot be replaced, and wear will occur after long-term use, affecting the safety of vehicle operation.

[0006] A single-opening turnout alloy steel combined frog includes a first wing rail, a second wing rail, and a fork retraction rail. The first wing rail is located on one side of the fork retraction rail, and the second wing rail is located on the other side of the fork retraction rail. The bottoms of the first wing rail, the second wing rail, and the fork retraction rail are all fixed together by fasteners. A combined tip is spliced ​​and installed on the outer surface of one end of the fork retraction rail. The end of the combined tip is a pointed structure, and a groove is provided on the inner side of the combined tip. The fasteners include a fixed base plate and two sets of sliding fasteners. Both sets of sliding fasteners are movably installed on the upper outer surface of the fixed base plate.

[0007] As a further technical solution of this utility model, the fork-removing guide rail includes a long guide rail and a short guide rail. The long guide rail is disposed on one side of the short guide rail, and one end of the long guide rail and the short guide rail are joined at an acute angle. The long guide rail and the short guide rail constitute the fork-removing guide rail, which plays a role in changing the track of the wheel.

[0008] As a further technical solution of this utility model, both the long and short core rails have beveled ends, and both the long and short core rails have I-shaped cross-sections. The beveled ends can reduce the resistance when the assembled pointed ends are connected.

[0009] As a further technical solution of this utility model, a sloping top block is fixedly installed at the inner middle position of the combined tip to cooperate with the sloping part. The bottom of the sloping top block is a sloping structure. By using the sloping top block to connect with the sloping part, the combined tip can maintain the same height as the surfaces of the long and short core rails after installation.

[0010] As a further technical solution of this utility model, the inner surface of the combined tip is fixedly installed with a second connecting plate on both sides of the inclined top block, and the two sets of second connecting plates are symmetrically arranged.

[0011] As a further technical solution of this utility model, each of the long and short core rails is provided with a first connecting plate for use with the second connecting plate. Since both the long and short core rails adopt an I-shaped structure design, when the combined tip is connected to the fork core rail, the second connecting plate and the first connecting plate overlap. The second connecting plate and the first connecting plate can be fixed from the side with bolts to complete the fixing operation of the combined tip.

[0012] As a further technical solution of this utility model, the sliding fastener and the fixed base plate are movably connected by a sliding groove. One side of the sliding fastener is provided with a docking slot, which can be used to clamp and fix the lower part of the first wing rail, the second wing rail and the fork center rail.

[0013] As a further technical solution of this utility model, both ends of the fixed base plate are fixed by connecting and fixing through fixed brackets. The fixed brackets have a groove in the middle, and a side-rotating baffle is movably installed on the inner side of the connecting groove. The fixed brackets can fix the installation of the fixed base plate by using bolts.

[0014] As a further technical solution of this utility model, the upper surfaces of both ends of the fixed base plate are provided with limiting grooves, and the slot of the fixed card seat is provided with protrusions that cooperate with the limiting grooves.

[0015] As a further technical solution of this utility model, the sliding fastener and the fixed base plate are locked together by a fastening bolt. One end of the fastening bolt is provided with a threaded pad. When the sliding fastener moves to the corresponding position, the fastening bolt is rotated to cooperate with the threaded pad to lock and fix the sliding fastener.

[0016] The beneficial effects of this utility model are as follows: By setting a combined tip, this utility model provides a combined installation structure at the end of the fork-removing rail when the single-opening turnout alloy steel combined frog is used, reducing damage to the fork-removing rail, enabling quick replacement of the fork-removing rail tip, and improving the stability of the fork-removing rail. During operation, one end of the combined tip is sleeved onto the ends of the long and short rails. The beveled portion reduces the resistance when the combined tip is connected. At the same time, the use of the beveled top block to connect the beveled portion ensures that the combined tip is at the same height as the surfaces of the long and short rails after installation. Since both the long and short rails adopt an I-shaped structure design, when the combined tip is connected to the fork-removing rail, the second connecting plate overlaps with the first connecting plate. The second connecting plate and the first connecting plate can be fixed from the side with bolts to complete the fixing operation of the combined tip, keeping the combined tip and the surface of the fork-removing rail flat and improving its stability in use.

[0017] By setting up fixing components, the fixing effect on the first wing rail, second wing rail, and forklift center rail is improved when this single-opening turnout alloy steel combination frog is used, allowing it to be adjusted arbitrarily according to the track structure, thus improving the flexibility of its assembly and installation. During operation, the sliding fastener's docking slot can be used to clamp and fix the lower part of the first wing rail, second wing rail, and forklift center rail. When the sliding fastener moves to the corresponding position, the fastening bolt is rotated in conjunction with the threaded pad to lock and fix the sliding fastener. Secondly, the side rotating baffle can be adjusted arbitrarily according to the side angle of the first wing rail, second wing rail, and forklift center rail, raising the sliding fastener to fit tightly against the side of the track. When the sliding fastener moves to the corresponding position, the fastening bolt is rotated in conjunction with the threaded pad to lock and fix the sliding fastener. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1-4 As shown, a single-opening turnout alloy steel combined frog includes a first wing rail 2, a second wing rail 3, and a fork retraction rail 6. The first wing rail 2 is located on one side of the fork retraction rail 6, and the second wing rail 3 is located on the other side of the fork retraction rail 6. The bottoms of the first wing rail 2, the second wing rail 3, and the fork retraction rail 6 are all fixed together by fasteners 1. A combined tip 7 is spliced ​​and installed on the outer surface of one end of the fork retraction rail 6. The end of the combined tip 7 is a pointed structure, and a groove is provided on the inner side of the combined tip 7. The fasteners 1 include a fixed base plate 11 and two sets of sliding fasteners 9. Both sets of sliding fasteners 9 are movably installed on the upper outer surface of the fixed base plate 11.

[0026] The fork-removing guide rail 6 includes a long guide rail 4 and a short guide rail 5. The long guide rail 4 is located on one side of the short guide rail 5. One end of the long guide rail 4 and the short guide rail 5 are joined at an acute angle. The long guide rail 4 and the short guide rail 5 are used to form the fork-removing guide rail 6, which plays a role in changing the track of the wheel.

[0027] Both the long core rail 4 and the short core rail 5 have beveled sections 13 at their ends. The cross-sections of the long core rail 4 and the short core rail 5 are I-shaped structures. The beveled sections 13 can reduce the resistance when the combined pointed ends 7 are connected.

[0028] An inclined top block 16 is fixedly installed on the inner middle of the combined pointed head 7 to cooperate with the inclined part 13. The bottom of the inclined top block 16 is an inclined structure. By using the inclined top block 16 to connect with the inclined part 13, the combined pointed head 7 can maintain the same height as the surfaces of the long core rail 4 and the short core rail 5 after installation.

[0029] The inner surface of the combined pointed head 7 is fixedly installed with second connecting plates 15 on both sides of the inclined top block 16, and the two sets of second connecting plates 15 are symmetrically arranged.

[0030] Both the long guide rail 4 and the short guide rail 5 have a first connecting plate 14 on one side for use with the second connecting plate 15. Since both the long guide rail 4 and the short guide rail 5 adopt an I-shaped structure design, when the combined tip 7 is connected to the fork guide rail 6, the second connecting plate 15 and the first connecting plate 14 overlap. The second connecting plate 15 and the first connecting plate 14 can be fixed from the side with bolts to complete the fixing operation of the combined tip 7.

[0031] The sliding fastener 9 and the fixed base plate 11 are connected by a sliding groove. The sliding fastener 9 has a docking slot 12 on one side. The docking slot 12 of the sliding fastener 9 can be used to clamp and fix the lower part of the first wing rail 2, the second wing rail 3 and the fork center rail 6.

[0032] Both ends of the fixed base plate 11 are fixed by connecting and fixing the fixed brackets 8. The fixed brackets 8 have a groove in the middle. A side-rotating baffle 18 is movably installed on the inner side of the connecting groove 12. The fixed brackets 8 can fix the installation of the fixed base plate 11 by using bolts.

[0033] The upper surfaces of both ends of the fixed base plate 11 are provided with limiting grooves 10, and the slots of the fixed card seat 8 are provided with protrusions that cooperate with the limiting grooves 10.

[0034] The sliding fastener 9 and the fixed base plate 11 are locked together by a fastening bolt 17. One end of the fastening bolt 17 is provided with a threaded pad. When the sliding fastener 9 moves to the corresponding position, the fastening bolt 17 is rotated to cooperate with the threaded pad to lock and fix the sliding fastener 9.

[0035] A single-opening turnout alloy steel combined frog, when in use, features a combined tip 7. This design provides a combined mounting structure at the end of the fork release rail 6, reducing damage to the fork release rail 6 and allowing for quick tip replacement, thus improving the stability of the fork release rail 6. During operation, one end of the combined tip 7 is fitted onto the ends of the long rail 4 and the short rail 5. The inclined surface 13 reduces resistance during the connection of the combined tip 7, while also utilizing the inclined surface... The top block 16 connects to the inclined surface 13, which allows the combined tip 7 to maintain the same height as the surfaces of the long and short center rails 4 and 5 after installation. Since both the long and short center rails 4 and 5 adopt an I-shaped structure design, when the combined tip 7 connects to the fork-removing center rail 6, the second connecting plate 15 overlaps with the first connecting plate 14. The second connecting plate 15 and the first connecting plate 14 can be fixed from the side with bolts to complete the fixing operation of the combined tip 7, so that the surfaces of the combined tip 7 and the fork-removing center rail 6 remain flat, thus improving its stability in use.

[0036] By setting the fixing component 1, the fixing effect on the first wing rail 2, the second wing rail 3, and the fork retraction rail 6 is improved when the single-opening turnout alloy steel combination frog is used, allowing it to be adjusted arbitrarily according to the track structure, thus improving the flexibility of its assembly and installation. During operation, the lower part of the first wing rail 2, the second wing rail 3, and the fork retraction rail 6 can be clamped and fixed by the docking slot 12 of the sliding fastener 9. When the sliding fastener 9 moves to the corresponding position, the sliding fastener 9 is locked and fixed by rotating the fastening bolt 17 in conjunction with the threaded pad. Secondly, the side rotating baffle 18 can be adjusted arbitrarily according to the side angle of the first wing rail 2, the second wing rail 3, and the fork retraction rail 6, so that the sliding fastener 9 is close to the side of the track. When the sliding fastener 9 moves to the corresponding position, the sliding fastener 9 is locked and fixed by rotating the fastening bolt 17 in conjunction with the threaded pad.

[0037] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
