Description

Technical Field

[0001] The utility model relates to the technical field of railway turnouts, and more specifically, to a linear structure of a crossover turnout. Background Art

[0002] At present, the lateral passing speed of the 12 - point movable - point frog crossover is not high. To improve the maintenance conditions of the diamond part, the prior art has made improvements to the single - turnout frog part. Widening the single - turnout frog part will move the turnout center forward. If the turnout center remains unchanged, problems such as inconsistent main dimensions between the single - turnout and the supporting crossover and non - universal rail components will occur, causing inconvenience to the yard layout and spare parts. Therefore, a new linear structure of the crossover turnout is needed to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a linear structure of a crossover turnout to improve the above problems. To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0004] The present application provides a linear structure of a crossover turnout, including: a switch and four single - turnout frogs. The four switches are arranged in parallel; the four single - turnout frogs intersect to form a diamond cross - structure. The straight - lateral gauge of all the switches and single - turnout frogs is 1435 mm.

[0005] Optionally, the diamond cross - structure includes two acute - angle frogs and two obtuse - angle frogs, and the center - point distance between the two obtuse - angle frogs is 1445 mm.

[0006] Optionally, the straight - lateral gauge from the single - turnout frog to the center - point of the obtuse - angle frog is 1435 mm to 1445 mm.

[0007] Optionally, the obtuse - angle frog is connected to the heel end of the single - turnout frog.

[0008] Optionally, the gauge of the single - turnout frog and the gauge of the obtuse - angle frog are transitioned within the obtuse - angle frog.

[0020] Embodiment 1

[0021] As Figure 1 shown, this embodiment provides a cross-over turnout linear structure, including: a switch 1 and a single-opening frog 2. There are four groups of the switches 1, and the four groups of the switches 1 are arranged in parallel; there are four groups of the single-opening frogs 2, and the four groups of the single-opening frogs 2 intersect to form a diamond crossing structure. The straight and lateral gauge of all the switches 1 and the single-opening frogs 2 is 1435 mm.

[0022] The main dimensions of the structural cross-over turnout of the present utility model, components such as the switch 1 and the movable-point frog are all consistent with the supporting single-opening turnout 2, which is convenient for yard design and subsequent maintenance, spare parts. And in this structure, the obtuse frog 3 and the single-opening part do not need to be connected by a matching rail 5, and the gauge and twist transition are directly completed inside the obtuse frog 3. This design structure makes the single-opening frog 2 and the cross-over turnout have consistency and unity, simplifies the procedures of production manufacturing and maintenance, reduces the possibility of on-site design and assembly errors, and indirectly reduces the construction labor cost.

[0023] Among them, the diamond crossing structure includes two acute frogs 4 and two obtuse frogs 3, and the center point distance between the two obtuse frogs 3 is 1445 mm.

[0024] It can be understood that through the design of this diamond crossing structure, the problem of railway line crossing can be effectively solved, ensuring that trains can safely and smoothly switch lines and converge at the crossing point. By reasonably designing the crossing structure, the transportation capacity and safety of railway lines can be improved, the running obstacles and delays of trains can be reduced, and the main dimensions and lengths of the single-opening frog 2 and the supporting cross-over turnout are the same in such a design, which is convenient for yard design.

[0025] Among them, the straight and lateral gauge from the single-opening frog 2 to the center point of the obtuse frog 3 is 1435 mm to 1445 mm.

[0026] It can be understood that through the design of this gauge range, it can be ensured that trains have sufficient space and a smooth transition when switching from the single-opening frog 2 to the obtuse frog 3. By reasonably controlling the gauge range, the vibration and running noise of trains can be effectively reduced, ensuring the safety and comfort of railway transportation. At the same time, the design of this range is also beneficial to the maintenance and management of track facilities, reducing the operation cost and maintenance difficulty.

[0027] Among them, the obtuse frog 3 is directly connected to the heel end of the single turnout 2.

[0028] It can be understood that the design of directly connecting the obtuse frog 3 to the heel end of the single turnout 2 can ensure the stability and reliability of the crossover structure, providing good support and guidance when the train passes. Through appropriate connecting components and technical measures, the firmness and durability of the connection can be guaranteed, thereby improving the operation safety and reliability of the railway line. At the same time, this connection method is also conducive to the maintenance and management of track facilities, reducing the operation cost and maintenance difficulty, making the single turnout 2 and the crossover consistent and unified, simplifying the production manufacturing and maintenance procedures, reducing the possibility of on-site design and assembly errors, and indirectly reducing the construction labor cost.

[0029] Among them, the gauge of the single turnout 2 is transitioned within the obtuse frog 3.

[0030] It can be understood that the design of the gauge transition between the single turnout 2 and the obtuse frog 3 can ensure that the train smoothly adjusts the track in the transition area, avoiding uneven or unstable conditions. By appropriately adjusting the gauge, the running smoothness of the train can be improved, reducing vibrations and noises during operation, while ensuring the transportation safety and smoothness of the railway line. This transition design is also conducive to the maintenance and management of track facilities, reducing the operation cost and maintenance difficulty.

[0031] Among them, the gauge transition length of the obtuse frog 3 is 1.3 m.

[0032] It can be understood that the design of the gauge transition length of the obtuse frog 3 can ensure that the train smoothly adjusts the track in the transition area, avoiding uneven or unstable conditions. By appropriately adjusting the transition length, the running smoothness of the train can be improved, reducing vibrations and noises during operation, while ensuring the transportation safety and smoothness of the railway line. This design of the transition length is also conducive to the maintenance and management of track facilities, reducing the operation cost and maintenance difficulty.

[0033] Among them, a matching rail 5 is provided between the obtuse frog 3 and the acute frog 4 for gauge transition.

[0034] It can be understood that by providing the matching rail 5 for gauge transition in the present utility model, it can effectively ensure the smooth operation of the train in the transition area between the obtuse frog 3 and the acute frog 4. The design of the matching rail 5 is seamlessly connected to the surrounding track structure, following relevant railway standards and specifications, ensuring the safety and stability of the transition area. This transition design helps to improve the transportation efficiency and safety of the railway line, while reducing the running obstacles and delays of the train.

[0035] Among them, the length of the matching rail 5 is 3.5 m.

[0036] It can be understood that the design with the length of the matching rail 5 being 3.5 m can effectively complete the gauge transition between the obtuse frog 3 and the acute frog 4, and ensure the smooth operation of the train in the transition area. The selection of this length takes into account factors such as the running speed of the train, the geometric characteristics of the track, and the layout of the crossover structure, ensuring the safety and stability of the transition area. Through the appropriate design of the matching rail 5, the transportation efficiency and safety of the railway line can be improved, and the running obstacles and delays of the train can be reduced.
