Description

Technical Field

[0001] This application relates to the field of railway turnout technology, and in particular to a snap-on structure for a double-spinning turnout. Background Technology

[0002] The switch rail is an important component of a railway switch. By moving the switch rail, the train is directed to the main line or siding. The end of the switch rail that connects to the guide rail is called the switch rail heel.

[0003] In related technologies, turnouts generally use rigid clamps to press the bottom of the curved tip rail to restrict the lateral displacement of the rail, and use blocks to restrict the position of the movable frog rail of the obtuse angle frog.

[0004] However, when the turnout gauge does not meet the requirements, these rigid buckles and blocks cannot effectively adjust the gauge, making on-site installation and use inconvenient. Furthermore, when the wheels pass through this position, they exert lateral force on the movable point rail, which can easily cause the movable point rail to shift laterally, creating a safety hazard. Summary of the Invention

[0005] This application provides a snap-on structure for a double-ended turnout, which solves the problem in related technologies that the moving point rail is easily deflected laterally when the wheel passes through the turnout.

[0007] A substrate, wherein a protruding platform is provided on the substrate;

[0008] The curved tip rail and the movable center rail are fixed on the base plate and the movable center rail is fixed on the platform.

[0019] In one possible implementation, the plate body is fixed to the K-shaped iron by through bolts, and a spring washer is sandwiched between the plate body and the K-shaped iron.

[0020] In one possible implementation, the bolt is a T-bolt.

[0037] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0039] As mentioned in the background art, in related technologies, turnouts generally use rigid clamps to press the bottom of the curved tip rail to restrict the lateral displacement of the rail, and use blocks to restrict the position of the movable frog rail of the obtuse angle frog.

[0040] However, when the turnout gauge does not meet the requirements, these rigid buckles and blocks cannot effectively adjust the gauge, making on-site installation and use inconvenient. Furthermore, when the wheels pass through this position, they exert lateral force on the movable point rail, which can easily cause the movable point rail to shift laterally, creating a safety hazard.

[0041] This application provides a snap-on structure for a double-headed turnout. By setting a platform on the base plate, a limiting gauge block is sandwiched between the curved tip rail and the platform. By replacing the limiting gauge blocks of different specifications, the position of the curved tip rail can be adjusted, thereby facilitating the adjustment of the gauge.

[0042] In addition, the fastener is configured to limit the displacement of the movable center rail in the lateral direction, thereby resisting the lateral force exerted on the movable center rail by the vehicle wheels when passing through the turnout, making the overall structure more stable.

[0043] The following description, in conjunction with the accompanying drawings, illustrates the buckle structure for a double-heading turnout in an embodiment of this application.

[0044] like Figure 1 As shown in the embodiment of this application, the snap-on structure for a double-heading turnout includes a base plate 100, on which a protruding platform 200 is provided; it also includes a curved tip rail 700 and a movable center rail 600, wherein the curved tip rail 700 is fixed on the base plate 100 and the movable center rail 600 is fixed on the platform 200; a limiting gauge block 300 is sandwiched between the curved tip rail 700 and the platform 200; a snap-on member 400 is fixed on the platform 200, the snap-on member 400 is located between the curved tip rail 700 and the movable center rail 600, and limits the displacement of the limiting gauge block 300 in the vertical direction, and the snap-on member 400 is configured to limit the displacement of the movable center rail 600 in the lateral direction.

[0045] As can be seen from the above description, since a limiting gauge block 300 is sandwiched between the curved tip rail 700 and the platform 200, the gap between the curved tip rail 700 and the platform 200 can be adjusted by replacing the limiting gauge block 300 with different sizes and specifications, thereby facilitating the adjustment of the turnout gauge; in addition, the fastener 400 is fixed on the platform 200, which can resist the lateral force on the movable center rail 600 when the vehicle wheels pass through the turnout, making the overall structure more stable.

[0046] It should be noted that in the embodiments of this application, the lateral direction refers to the width direction along the track, and the vertical direction refers to the height direction along the track, which will not be repeated below.

[0047] The base plate 100 and the platform 200 can be integrally formed, or the platform 200 can be welded and fixed to the base plate 100. It should be noted that the height of the platform 200 is higher than that of the base plate 100, but the upper surface of the movable center rail 600 and the curved tip rail 700 set on the platform 200 are at the same level, thereby ensuring the normal operation of the train.

[0048] like Figure 1As shown, the fastener 400 described in this embodiment includes a main body 401, a first limiting part 402, a second limiting part 403, and a support part 404.

[0049] The plate body 401 is fixed to the platform 200 by fasteners passing through it; the first limiting part 402 is bent relative to the plate body 401 and is used to abut against the limiting gauge block 300; the second limiting part 403 protrudes along the plate body 401 toward the movable center rail 600 and is used to abut against the rail web of the movable center rail 600; the supporting part 404 protrudes along the plate body 401 toward the platform 200 and is used to support the plate body 401.

[0050] Figure 1 In the middle, the function of the first limiting part 402 is to press against the fixed limiting gauge block 300 and prevent the limiting gauge block 300 from shifting in the vertical direction. The second limiting part 403 presses against the web of the movable center rail 600 and provides support for the movable center rail 600 in the lateral direction to counteract the lateral force on the movable center rail 600 when the vehicle wheels pass through the turnout.

[0051] Furthermore, the fastener 400 is engaged with the bottom of the movable center rail 600. For example, the fastener 400 is engaged with the step 101 surface where the bottom of the movable center rail 600 is located. This setting can enhance the lateral limiting effect of the fastener 400 on the platform 200 on the one hand, and can also limit and prevent the movable center rail 600 from shifting in the vertical direction on the other hand.

[0052] In addition, as an alternative implementation, the platform 200 is provided with a K-shaped iron 500, and the main body 401 of the plate is fixed on the K-shaped iron 500; the platform 200 is provided with a slot 201, the support part 404 is provided in the slot 201, and a compensation block 202 is sandwiched between the side of the support part 404 away from the movable center rail 600 and the slot 201.

[0053] Here, the function of the aforementioned compensation block 202 is to ensure that the fastener 400 can be tightly pressed against the movable center rail 600. When an error occurs in the actual assembly, compensation blocks 202 of different specifications can be replaced, as long as the fastener 400 can be tightly pressed against the movable center rail 600.

[0054] In this embodiment, the K-type iron 500 can be a K-type iron seat related to railway tracks. The K-type iron 500 has a threaded hole and a through hole on the fastener plate 400. The plate body 401 is fixed to the K-type iron 500 by a bolt 405. A spring washer 406 is sandwiched between the plate body 401 and the K-type iron 500.

[0055] Preferably, the bolt 405 is a T-bolt, and a nut is threaded onto the bolt 405, with an anti-rotation plate on the nut. Here, the use of a nut and spring washer 406 to fasten the bolt prevents the bolt from extending deep into the safety flange groove, thus ensuring a stable installation while avoiding damage to the turnout.

[0056] As can be seen from the above description, the first limiting part 402 of the fastener 400 clamps and fixes the curved tip rail 700, and the second limiting part 403 abuts against the movable center rail 600, thereby ensuring the lateral support of the fastener 400 for the movable center rail 600.

[0057] In some embodiments, a step 101 is provided between the substrate 100 and the platform 200, one side of the limiting gauge block 300 is engaged with the step 101, and the other side is engaged with the bottom of the curved tip rail 700 to limit the vertical displacement of the curved tip rail 700.

[0058] The curved tip rail 700, as described above, is fixed to the base plate 100 on the side opposite to the movable center rail 600 by a spring clip 301. A gauge block 302 is also provided between the spring clip 301 and the bottom of the curved tip rail 700. Therefore, by replacing the gauge blocks 300 of different specifications, the position of the curved tip rail 700 in the lateral direction can be adjusted, thereby achieving gauge adjustment.

[0059] In the embodiments of this application, the substrate 100 and the platform 200 may be made of metal plates, such as iron plates or copper plates, and there is no absolute limitation on this.

[0060] like Figure 1 and Figure 2 As shown in the embodiment of this application, the snap-on structure for a double-spinning turnout includes a curved tip rail 700 fixed to a base plate 100, with a spring clip 301 securing the side of the curved tip rail 700 away from the movable center rail 600. The movable center rail 600 of the obtuse-angle frog is placed on a platform 200, which is welded to or integrally formed with the base plate 100. A limiting gauge is placed between the bottom of the curved tip rail 700 and the platform 200, and the position of the curved tip rail 700 can be adjusted by replacing the limiting gauge blocks 300 and fixed gauge blocks 302 of different specifications.

[0061] One side of the fastening plate 400 is fastened to the limiting gauge block 300 to restrict its vertical displacement, while the other side supports the web of the movable center rail 600. When a vehicle passes, it resists lateral loads. The fastening plate 400 is connected to the K-shaped iron 500 welded to the platform 200 by bolts, nuts and spring washers 406. The position of the fastening plate 400 can be adjusted by the compensation block 202 to make it abut against the web of the movable center rail 600, so as to give full play to its supporting role.

[0062] The limiting gauge block 300 restricts its lateral and longitudinal displacement by the rail and the platform 200, and its vertical position is restricted by the fastening plate 400 to ensure its safety and stability. The position of the fastening plate 400 can be adjusted by replacing the compensation block 202 of different specifications. The adjusting plate needs to fit tightly with the slot 201 of the platform 200 to prevent it from moving out longitudinally.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
