The first and second curved switch rails are equipped with a traction and displacement device at their ends corresponding to the double-track turnout. Under the control of this device, the first and second curved switch rails have two working positions: In the first position, there is a gap between the second curved switch rail and the second main rail on the side facing the curved main rail, and they are not in close contact; there is also a gap between the inner sides of the first curved switch rail and the first straight main rail, and they are not in close contact. In the second position, the second curved switch rail and the second main rail are in close contact on the side facing the curved main rail, and there is a gap between the inner sides of the first curved switch rail and the first straight main rail, and they are not in close contact. This invention achieves derailment by expanding the track gauge, resulting in a smaller impact angle, a smaller impact force, a sufficiently large derailment coefficient, and a higher derailment success rate.

Description

Technical Field

[0001] This invention relates to the field of turnout derailment equipment technology, specifically to a turnout derailment device with a smaller impact angle, a sufficiently large derailment coefficient, and a higher derailment success rate. Background Technology

[0002] A derailer is a turnout derailment device that derails locomotives and rolling stock from the track. As a bidirectional isolation device in railway protection zones, it forces locomotives and rolling stock entering the protection zone from any direction to derail, ensuring transportation safety and the personal safety of personnel. The X9801 derailer is based on the Hayes XB6 derailer used in the United States in the early 20th century. As a turnout track separation device, the X9801 derailer is a safety device used to prevent locomotives and rolling stock from accidentally or illegally entering the protected track. In actual use, it has been found that the failure scenarios of the X9801 derailer are basically the same: loaded cars often damage the derailer, while empty cars often skip it. Analysis shows that there are three main reasons why the X9801 derailer fails to derail:

[0003] 1. The derailment coefficient is too small and the cross-sectional design is unreasonable. For example, the invention patent application CN112441061A, entitled "A Derailer with Buffer Function," has a structure similar in principle to the X9801 type derailer, which achieves forced derailment by the wheel entering the guide plate. Because the angle of its guide plate is relatively harsh and the impact angle is large, the derailment coefficient of the wheel is small. Furthermore, the cross-sectional structure of its guide plate is unreasonable, making the derailer prone to failure when the derailment coefficient is small.

[0004] 2. The larger impact angle causes the derailer to withstand greater impact force, which requires higher structural strength of the derailer. When the structural strength of the derailer is insufficient, this type of derailer is easily damaged under the impact of locomotives and rolling stock when guiding a heavy car to derail.

[0005] 3. The anti-reverse and anti-jump mechanism of the X9801 derailer is poor. It often fails to function due to retraction under the impact of locomotives and rolling stock. It also has poor adaptability and cannot be used for derailment of turnouts of various track gauges. Summary of the Invention

[0006] To address the shortcomings of the aforementioned technologies, this invention provides a turnout derailer with a smaller impact angle, a sufficiently large derailment coefficient, and a higher derailment success rate.

[0007] The technical solution adopted by the present invention to achieve the above-mentioned technical effects is as follows:

[0008] A derailment device for a switchgear includes a first straight main rail, a second main rail, a first curved switch rail, a second curved switch rail, and a curved main rail. The first straight main rail corresponds to a corresponding side rail of the switchgear, the second main rail corresponds to the switchgear rail of the switchgear, and the curved main rail corresponds to the other corresponding side rail of the switchgear. The first curved switch rail and the second curved switch rail are provided with a traction displacement device at one end corresponding to the switchgear. Under the drive control of the traction displacement device, the first curved switch rail and the second curved switch rail have two positions: a first state and a second state.

[0009] In the first state, the second curved tip rail and the second basic rail are spaced apart on the side facing the curved basic rail, and are not in close contact. The first curved tip rail and the inner side of the first straight basic rail are also spaced apart, and are not in close contact.

[0010] In the second state, the second curved tip rail and the second base rail are in close contact on the side facing the curved base rail, while there is a gap between the inner sides of the first curved tip rail and the first straight base rail, and they are not in close contact.

[0011] Preferably, in the above-mentioned turnout derailment device, the traction displacement device includes a horizontally placed traction rod and a first connector and a second connector disposed on the traction rod. The first connector is fixedly connected to the inner side of the first curved switch rail, and the second connector is fixedly connected to the inner side of the second curved switch rail.

[0012] Preferably, in the above-mentioned switch derailment device, the first connector and the second connector have the same structure and are detachably mounted on the pull rod.

[0013] Preferably, in the above-mentioned turnout derailment device, the first connector includes an iron base, the lower end of which is assembled on the traction rod by a screw and nut, the upper end of which is connected to an iron arm by a fixed shaft, and the outer end of the iron arm is provided with a connecting iron block, which is fixedly connected to the inner side of the first curved switch rail.

[0014] Preferably, in the above-mentioned turnout derailment device, the connecting iron block is detachably fixed to the inner side of the first curved switch rail by bolts.

[0015] Preferably, in the above-mentioned turnout derailment device, the outer side of the first curved tip rail is formed with a fitting surface that matches the curvature of the inner working surface of the first straight main rail, and the outer side of the second curved tip rail is formed with a fitting surface that matches the curvature of the working surface of the second main rail on the side facing the curved main rail.

[0016] Preferably, the above-mentioned turnout derailer further includes a pad for supporting the first straight main rail, the second main rail, the first curved switch rail, the second curved switch rail, and the curved main rail. The pad is also provided with a slide plate at the position corresponding to the traction displacement device, and the traction rod is movably mounted on the slide plate.

[0017] Preferably, in the above-mentioned switch derailment device, the first straight main rail, the second main rail, the first curved switch rail, the second curved switch rail, and the curved main rail are structural components used in ordinary switch turnouts.

[0018] Preferably, in the above-mentioned turnout derailment device, the first curved switch rail, the second curved switch rail, and the curved main rail are all structural components designed with a guide curve.

[0019] The beneficial effects of the present invention are as follows: The turnout derailer of the present invention achieves derailment of the expanded gauge by adopting the first curve switch rail, the second curve switch rail and the main curve rail designed with the guide curve. The impact angle is small and the impact force is also small. Therefore, the derailment coefficient is large enough and the derailment success rate is higher. At the same time, trains of various gauges can use the same set of derailers for derailment, which makes it more adaptable. Attached Figure Description

[0029] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] Please see Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of the present invention proposes a turnout derailment device, which includes a first straight main rail 1, a second main rail 2, a first curved switch rail 3, a second curved switch rail 4, and a curved main rail 5. The first curved switch rail 3, the second curved switch rail 4, and the curved main rail 5 are all structural components with a guide curve design. Specifically, in this invention, the first straight main rail 1 corresponds to one side rail of the turnout, the second main rail 2 corresponds to the switch rail of the turnout, and the curved main rail 5 corresponds to the other side rail of the turnout. Specifically, the first curved switch rail 3 and the second curved switch rail 4 are provided with a traction displacement device 6 at one end corresponding to the turnout. Under the drive control of the traction displacement device 6, the first curved switch rail 3 and the second curved switch rail 4 have two positions: a first state and a second state. In the first state, the second curved switch rail 4 and the second main rail 2 have a gap between them on the side facing the curved main rail 5, and they are not in close contact. Figure 6 As shown, there is a gap between the inner sides of the first curved tip rail 3 and the first straight basic rail 1; they are not in close contact. In the second state, as... Figure 7 As shown, the second curved tip rail 4 and the second basic rail 2 are closely fitted on the side facing the curved basic rail 5, while the first curved tip rail 3 and the inner side of the first straight basic rail 1 have a gap and are not closely fitted. Figure 4In the illustrated state, the train is traveling on a track with a larger gauge. When derailment is required, the first curved switch rail 3 and the second curved switch rail 4 are positioned in the first state by the traction displacement device 6. At this time, there is a gap between the second curved switch rail 4 and the second main rail 2 on the side facing the curved main rail 5; they are not in close contact. The left wheel 100 enters the second main rail 2, while the right wheel 200 has no corresponding straight main rail. Therefore, the right wheel 200 enters the curved main rail 5 and remains on it. As the wheels continue to travel, the gauge between the left wheel 100 and the right wheel 200 gradually increases until the wheels fall off and derailment is complete. Its derailment principle differs from that of the X9801 type derailer; it does not guide the wheels off the rail through guide plates, but rather derails by gradually increasing the gauge.

[0031] When a train is traveling on a track with a narrow gauge, and derailment needs to be controlled, the first curved switch rail 3 and the second curved switch rail 4 are positioned in a second state by the traction displacement device 6. At this time, the second curved switch rail 4 is in close contact with the second base rail 2 on the side facing the curved base rail 5, while the first curved switch rail 3 has a gap between its inner side and the inner side of the first straight base rail 1, meaning they are not in close contact. Because the second curved switch rail 4 is in close contact with the second base rail 2, the right wheel traveling on the narrow gauge track enters the second curved switch rail 4. Since the first curved switch rail 3 has a gap between its inner side and the inner side of the first straight base rail 1, the left wheel enters the first straight base rail 1. As the wheels continue to travel, the track gauge traveled by the left and right wheels gradually increases until the wheels fall off, completing the derailment. By controlling the changes in the positions of the first and second states, derailment of trains traveling on large-gauge tracks and trains traveling on narrow-gauge tracks can be controlled respectively, thus improving the applicability of the derailment device of this invention.

[0032] Furthermore, in a preferred embodiment of the present invention, such as Figure 2 As shown, the traction and displacement device 6 includes a horizontally placed traction rod 61 and a first connector 62 and a second connector 63 disposed on the traction rod 61. The first connector 62 is fixedly connected to the inner side of the first curved tip rail 3, and the second connector 63 is fixedly connected to the inner side of the second curved tip rail 4. The positional changes of the first curved tip rail 3 and the second curved tip rail 4 can be controlled by the traction guidance of the traction rod 61. For ease of replacement and maintenance, in an embodiment of the present invention, the first connector 62 and the second connector 63 have identical structures and are detachably disposed on the traction rod 61. As a preferred embodiment of the present invention, as shown... Figure 5As shown, the first connector 62 includes an iron base 621. The lower end of the iron base 621 is mounted on the pull rod 61 via a screw and nut. The upper end of the iron base 621 is connected to an iron arm 622 via a fixed shaft 624. The outer end of the iron arm 622 is provided with a connecting iron block 623, which is fixedly connected to the inner side of the first curved tip rail 3. To prevent the iron base 621 from rotating, the iron base 621 adopts a square column structure. The pull rod 61 is provided with a recessed square groove 611. The square column structure of the iron base 621 is partially embedded in the recessed square groove 611, which can improve stability and prevent rotation due to force during use. In some embodiments, the connecting iron block 623 is detachably fixed to the inner side of the first curved tip rail 3 by bolts. The bolt connection facilitates the replacement of the connecting iron block 623.

[0033] Furthermore, in a preferred embodiment of the present invention, such as Figure 5 As shown, the outer side of the first curved tip rail 3 is formed with a fitting surface 31 that matches the curvature of the inner working surface of the first straight base rail 1, and the outer side of the second curved tip rail 4 is formed with a fitting surface that matches the curvature of the working surface of the second base rail 2 on the side facing the curved base rail 5.

[0034] In some embodiments, such as Figure 6 As shown, it also includes a pad 7 for supporting the first straight main rail 1, the second main rail 2, the first curved switch rail 3, the second curved switch rail 4, and the curved main rail 5. The pad 7 is further provided with a slide plate 8 at the position corresponding to the traction displacement device 6, and the traction rod 61 is laterally movable on the slide plate 8. In a preferred embodiment of the invention, the first straight main rail 1, the second main rail 2, the first curved switch rail 3, the second curved switch rail 4, and the curved main rail 5 are structural components used in ordinary turnouts. Therefore, they can be maintained together during routine maintenance, and ordinary lines can also be converted into this type of derailer by replacing parts.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
