Description

Technical Field

[0001] The present application relates to the field of rail transit equipment, and in particular to an anti-dancing whip. Background Art

[0002] In the electrified railway sector, the stable operation of the catenary system is crucial for ensuring train power supply and operational safety. The catenary's catenary cables, the primary structure supporting the contact wire, maintain their position via droppers installed every 8 to 12 meters. This allows the locomotive's pantograph to smoothly contact the contact wire and draw current during operation. To ensure this smooth process, the catenary system is equipped with a tension compensation system that dynamically adjusts the tension of the cables and contact wire to maintain a constant height above the rails, thus preventing unstable current drawing or catenary failures caused by height fluctuations.

[0003] However, despite these technical safeguards, catenary galloping can still occur under adverse weather conditions, such as when the cables are covered with icing. This not only increases equipment wear but can also affect the normal flow of electricity from locomotives, and even lead to serious power outages. To address this issue, an anti-galloping whip has been introduced. Its primary function is to suppress vibration and galloping of the catenary by disrupting the galloping airflow caused by cable icing.

[0004] The anti-dancing whip design that is currently widely used usually adopts a combination of two grip sections and one anti-dancing section. This design can effectively reduce the dancing of the contact net to a certain extent. However, since there is only one anti-dancing section, the anti-dancing coverage area is limited, and the anti-dancing effect may not be ideal. Utility Model Content

[0005] In view of this, the purpose of this application is to overcome the deficiencies in the prior art and provide an anti-dancing whip.

[0006] To achieve the above objectives, the technical solutions adopted in this application are as follows:

[0007] This application provides:

[0008] An anti-dancing whip is used for spirally winding around a load-bearing cable, and the anti-dancing whip includes a first gripping section and a second gripping section;

[0009] a third gripping segment, the third gripping segment being located between the first gripping segment and the second gripping segment;

[0010] Among them, a first anti-dancing section is provided between the second gripping section and the third gripping section, and a second anti-dancing section is provided between the first gripping section and the third gripping section.

[0011] Furthermore, the anti-dancing whip is a round metal rod or a composite cable.

[0012] Furthermore, the metal rod includes a first metal layer and a second metal layer, the second metal layer is located on the outer surface of the first metal layer, and the density of the second metal layer is greater than the density of the first metal layer.

[0013] Furthermore, the first metal layer and the second metal layer are coaxial, and a distance between an outer surface of the second metal layer and an outer surface of the first metal layer is smaller than a radius of the first metal layer.

[0014] Furthermore, the composite cable is formed by twisting a plurality of the round metal bars.

[0015] Furthermore, the composite cable includes an inner core and outer wires, and the outer wires are multiple and evenly arranged about the axis of the inner core.

[0016] Furthermore, the length of the anti-dancing whip is between 4.5m and 7.5m.

[0017] Furthermore, the sum of the lengths of the first anti-dancing section and the second anti-dancing section accounts for 82% to 87% of the length of the anti-dancing whip.

[0018] Furthermore, the inner diameter of the spirally wound first gripping section, the inner diameter of the spirally wound second gripping section, and the inner diameter of the spirally wound third gripping section are all smaller than the diameter of the load-bearing cable.

[0019] Furthermore, the inner diameter of the spirally wound first anti-dancing section and the inner diameter of the spirally wound second anti-dancing section are both larger than the diameter of the catenary.

[0020] The present application provides a first anti-dancing section between the second gripping section and the third gripping section, and a second anti-dancing section between the first gripping section and the third gripping section, so that the anti-dancing whip has two anti-dancing sections, thereby improving the anti-dancing effect of the anti-dancing whip, and improving the holding force between the anti-dancing whip disclosed in the present application and the load-bearing cable through the first gripping section, the second gripping section and the third gripping section, thereby preventing the anti-dancing whip from detaching from the load-bearing cable.

[0035] The anti-dancing whip 100 disclosed in the present application is spirally wound on the load-bearing rope 400. The anti-dancing whip 100 mainly improves the anti-dancing effect by providing anti-dancing sections at both ends. Compared with the existing anti-dancing whip 100 with only one anti-dancing section, the anti-dancing effect of the anti-dancing whip 100 with two anti-dancing sections is better.

[0036] In this embodiment, the anti-dancing whip 100 includes a first gripping section 110, a second gripping section 120 and a third gripping section 130, and the third gripping section 130 is located between the first gripping section 110 and the second gripping section 120; wherein; a first anti-dancing section 140 is provided between the second gripping section 120 and the third gripping section 130, and a second anti-dancing section 150 is provided between the first gripping section 110 and the third gripping section 130.

[0037] See Figure 1 As shown, the entire anti-dancing whip 100 is wound around the load-bearing rope 400 by the first gripping section 110 and the second gripping section 120, and the anti-dancing whip 100 is fixed by the gripping force between the first gripping section 110, the second gripping section 120 and the load-bearing rope 400; in order to further improve the gripping connection force between the anti-dancing whip 100 and the load-bearing rope 400, a third gripping section 130 is provided between the first gripping section 110 and the second gripping section 120 to be wrapped around and fixed to the load-bearing rope 400.

[0038] The anti-dancing effect of the load-bearing cable 400 is improved by providing two anti-dancing sections, namely a first anti-dancing section 140 provided between the second grip section 120 and the third grip section 130 , and a second anti-dancing section 150 provided between the first grip section 110 and the third grip section 130 .

[0039] The anti-dancing whip 100 is a round metal rod or a composite cable, and the composite cable is formed by twisting a plurality of the round metal rods.

[0040] Existing anti-dancing whips are generally made of plastic. In order to increase the service life of the anti-dancing whip 100, the entire anti-dancing whip 100 is made of metal. Compared with plastic, metal is more durable, thereby increasing the maintenance cycle and reducing the maintenance frequency.

[0041] See Figure 2 and Figure 3 As shown, specifically, the anti-dancing whip 100 can be made of a single metal rod, or can be made by twisting multiple metal rods. In actual use, the choice can be made according to actual conditions.

[0042] The metal rod includes a first metal layer 210 and a second metal layer 220 . The second metal layer 220 is located on the outer surface of the first metal layer 210 , and the density of the second metal layer 220 is greater than that of the first metal layer 210 .

[0043] See Figure 3As shown, in order to reduce the overall weight of the metal rod, two materials with different densities are used to make it. The second metal layer 220 is located on the outer surface of the first metal layer 210, wherein the density of the first metal layer 210 is less than the density of the second metal layer 220. In this embodiment, in order to make the metal rod more durable and prevent the outer surface from rusting, the first metal layer 210 can be selected from aluminum and the second metal layer 220 can be selected from copper.

[0044] The first metal layer 210 and the second metal layer 220 are coaxial, and a distance between an outer surface of the second metal layer 220 and an outer surface of the first metal layer 210 is smaller than a radius of the first metal layer 210 .

[0045] Continue reading Figure 3 In order to further reduce the quality of the metal rod, the thickness of the first metal layer 210 is greater than the thickness of the second metal layer 220, that is, the radius of the first metal layer 210 is greater than the distance between the outer surface of the second metal layer 220 and the outer surface of the first metal layer 210. For example, the radius of the first metal layer 210 is R, and the distance between the outer surface of the second metal layer 220 and the outer surface of the first metal layer 210 is L, which can meet the following conditions: R>L.

[0046] In this embodiment, the purpose of making the radius of the first metal layer 210 larger than that of the second metal layer 220 is to reduce the weight of the second metal layer 220. That is, when the radius of the first metal layer 210 is larger than that of the second metal layer 220, the volume proportion of the second metal layer 220 becomes smaller accordingly, and the corresponding weight proportion also becomes smaller.

[0047] Specifically, in practice, the radius of the first metal layer 210 is much larger than the distance between the outer surface of the second metal layer 220 and the outer surface of the first metal layer 210 , and only a thinner second metal layer 220 needs to be set on the outer surface of the first metal layer 210 .

[0048] For example, the radius of the first metal layer 210 and the thickness of the second metal layer 220 are limited based on the thickness relationship, so that the first metal layer 210 accounts for a larger proportion, thereby making the anti-dancing whip 100 lighter overall.

[0049] The composite cable includes an inner core 200 and outer wires 300 . There are multiple outer wires 300 , and the multiple outer wires 300 are evenly arranged about the axis of the inner core 200 .

[0050] See Figure 2 As shown, the anti-dancing whip 100 is formed by twisting a plurality of metal bars, that is, a plurality of outer wires 300 are provided on the outer surface of the inner core 200 , and the plurality of outer wires 300 are twisted around the inner core 200 , thereby fixing the plurality of outer wires 300 .

[0051] In this embodiment, the inner core 200 and the outer wire 300 are both round metal rods.

[0052] In one embodiment, the length of the anti-dancing whip 100 is between 4.5m and 7.5m.

[0053] Since the distance between two adjacent hanging strings 500 is usually 8m to 12m, in order to prevent the two ends of the anti-dancing whip 100 from contacting the hanging strings 500, the length of the anti-dancing whip 100 is selected within a safe range. The length of the anti-dancing whip 100 can be selected between 4.5m and 7.5m. In this embodiment, the length of the anti-dancing whip 100 is selected to be 5.5m. Of course, other lengths can also be selected in practice, which is not limited here. For example, if the length of the anti-dancing whip 100 is shorter, two anti-dancing whips 100 can be installed while ensuring that they do not contact the hanging strings 500.

[0054] The sum of the lengths of the first anti-dancing section 140 and the second anti-dancing section 150 accounts for 82% to 87% of the length of the anti-dancing whip 100 .

[0055] In order to ensure that the anti-dancing whip 100 has sufficient anti-dancing sections, the first anti-dancing section 140 and the second anti-dancing section 150 constitute a total anti-dancing section. The length of the total anti-dancing section composed of the first anti-dancing section 140 and the second anti-dancing section 150 accounts for a certain proportion of the anti-dancing whip 100. Specifically, the length of the total anti-dancing section accounts for 82% of the length of the anti-dancing whip 100. The anti-dancing section of the existing anti-dancing whip 100 generally accounts for 75%, which results in the anti-dancing section being unable to achieve a better anti-dancing effect. For this reason, the total anti-dancing section is set to account for 82% of the length of the anti-dancing whip 100, thereby greatly improving the anti-dancing effect.

[0056] Furthermore, the total anti-dancing section length accounts for 87% of the length of the anti-dancing whip 100, thereby further improving the anti-dancing effect. If this proportion is exceeded, the first holding section 110, the second holding section 120 and the third holding section 130 may fall off and separate due to insufficient holding distance with the load-bearing rope 400. Preferably, the sum of the lengths of the first anti-dancing section 140 and the second anti-dancing section 150 accounts for 85% of the length of the anti-dancing whip 100. Therefore, under the premise of meeting the anti-dancing effect, the first holding section 110, the second holding section 120 and the third holding section 130 can also be fully held with the load-bearing rope 400 to prevent separation. In practice, other proportions can be selected according to actual conditions, and the specific ratio is not limited here.

[0057] The inner diameter of the spirally wound first gripping section 110 , the inner diameter of the spirally wound second gripping section 120 , and the inner diameter of the spirally wound third gripping section 130 are all smaller than the diameter of the catenary cable 400 .

[0058] By having the spirally wound inner diameter of the first gripping section 110, the second gripping section 120 and the third gripping section 130 of the anti-dancing whip 100 smaller than the diameter of the load-bearing cable 400, the anti-dancing whip 100 can be tightly fixed on the load-bearing cable 400 by increasing the gripping force wrapped around the load-bearing cable 400, thereby preventing the anti-dancing whip 100 from falling off the load-bearing cable 400 due to excessive wind or other external forces.

[0059] The inner diameter of the spirally wound first anti-dancing section 140 and the inner diameter of the spirally wound second anti-dancing section 150 are both larger than the diameter of the catenary cable 400 .

[0060] The first anti-dancing section 140 and the second anti-dancing section 150 are wound around the catenegro 400, thereby changing the diameter of the catenegro 400 at the positions of the first anti-dancing section 140 and the second anti-dancing section 150, and along the axial direction of the catenegro 400, as the first anti-dancing section 140 and the second anti-dancing section 150 are wound, the outer surface shape thereof is constantly changing, thereby destroying the conditions for the catenegro 400 to produce dancing.

[0061] See Figure 1 and Figure 4 As shown, the first gripping segment 110 and the second gripping segment 120 are both wrapped around the load-bearing cable 400 three times, and the third gripping segment 130 is wrapped around twice. The distance between two adjacent circles when the first gripping segment 110, the second gripping segment 120 and the third gripping segment 130 are wrapped is not limited here, and the distance between two adjacent circles can be increased or decreased in practice.

[0062] Continue reading Figure 1 and Figure 4 As shown, the first anti-dancing section 140 and the second anti-dancing section 150 are both wrapped around two sections of the load-bearing rope 400. Similarly, when the first anti-dancing section 140 and the second anti-dancing section 150 are wrapped around, the spacing between adjacent wrapped circles can be adjusted according to actual installation conditions, provided that the sum of the first anti-dancing section 140 and the second anti-dancing section 150 accounts for 82% to 87% of the anti-dancing whip 100, and is not limited here.

[0063] See Figure 5As shown, the additional wire 700 is arranged and installed between two mounting posts. In addition to being installed on the load-bearing cable 400, the anti-dancing whip 100 can also be installed on the additional wire 700 to suppress the vibration and dancing of the additional wire 700. When the anti-dancing whip 100 is installed on the additional wire 700, the structure does not have a suspension string 500 and a contact wire 600, so it can be evenly installed in multiple locations. In this example, the anti-dancing whip 100 is installed on the additional wire 700 at two locations. The installation spacing between the two anti-dancing whips 100 can be adjusted according to actual conditions, and the distance between the anti-dancing whip 100 and the mounting post where the additional wire 700 is installed can be adjusted according to actual conditions, and this is not limited here. In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any suitable manner in any one or more embodiments or examples. In addition, those skilled in the art can combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without conflicting with each other.

Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
