Description

Technology Field

[0001] The present invention relates to a tongue rail rigidity reinforcing device using a top plate fastening device for a railway turnout, wherein the reinforcing device is supported on the elastic part of the tongue rail without additional processing of the tongue rail to enhance structural stability, and the invention relates to a tongue rail reinforcing device for preventing detachment in the event of tongue rail breakage due to fatigue accumulation caused by a train passing through the turnout. Background Technology

[0003] A switch is a device that allows a railway vehicle to move from one track to an adjacent track.

[0004] These switches allow the selection of the railway vehicle's movement path by the movement of the tongue rail, which moves adjacently in the direction of the main rail or in the opposite direction.

[0005] The above tongue rail plays an important role in changing the direction of railway vehicles by constantly moving along the sliding upper surface of the switch, but wear, surface defects, and chipping occur due to contact friction between the wheel and the tongue rail and lateral pressure during switching. The tip of the tongue rail is sharp, and the rear end has a structure in which an elastic part with a small cross-sectional area is formed so that the width of the rail bottom is concave by a certain length to allow for smooth switching of the tongue rail and to reduce the switching force of the switch.

[0006] In particular, horizontal bending stress acts on the elastic part of the tongue rail during switching, and vertical bending stress acts due to wheel load when the vehicle passes, so a fracture problem may occur due to stress concentration.

[0007] The biggest problem mentioned above is the occurrence of excessive displacement in the elastic part of the tongue rail, and this displacement exceeds the elastic displacement limit of the tongue rail, and in severe cases, it leads to damage and train derailment.

[0008] Korean Published Patent No. 2010-0067350 (June 21, 2010) presents a device and method for fastening a top plate of a fixed part for a railway turnout, which supports a tongue rail and a base rail at the point part of a railway turnout, and in particular, is installed at the rear end fixing part of the tongue rail to firmly fasten the tongue rail fixing part where a height difference occurs between the tongue rail and the base rail, while simultaneously improving track stability at the point part, simplifying parts, reducing maintenance costs, increasing passing speed inside the turnout due to increased train speed, and improving ride comfort by reducing noise and vibration.

[0009] In addition, Korean registered patent No. 10-1254671 (April 9, 2013) is mainly characterized by providing a roller top plate for a railway turnout that eliminates the need for lubrication by integrating a roller cover with a built-in roller in the point top plate, thereby significantly reducing the frictional force between the point top plate and the tongue rail through the rotational force of the roller when the tongue rail moves, thereby reducing the switching force, increasing the contact force between the base rail and the tongue rail, and installing a roller frame on the central side of the point top plate to reduce the frictional force when the tongue rail switches.

[0010] In addition, Korean registered patent No. 20-0348053 (April 7, 2004) discloses a point top plate fastening device for a railway turnout that supports the tongue rail and the base rail at the point section of the railway turnout, facilitates the left and right movement of the tongue rail, is environmentally friendly due to the absence of lubrication, and improves ride comfort by reducing noise and vibration, as well as improving track stability, simplifying parts, reducing maintenance costs, and increasing the speed of passing through the turnout due to increased train speed.

[0011] Finally, Korean registered patent No. 20-0432442 (November 27, 2006) discloses a point plate fastening device for a turnout that reduces friction between the point plate and the tongue rail by using a roller to move the tongue rail, thereby reducing the switching force, increases the contact force between the base rail and the tongue rail, prevents bearing damage caused by shaft friction by special surface treatment of the roller's rotation axis by carbon carburization, thereby strengthening the lifespan, and reduces friction by coating the sliding surface of the plate with a solid lubricant, thereby eliminating the need for lubrication.

[0012] However, the above-mentioned conventional technologies are focused on ensuring that the tongue rail of the turnout slides smoothly on the sliding surface of the upper plate, and there was a problem in that they did not consider methods to prevent plastic deformation or fracture caused by fatigue stress due to frequent plastic deformation when the tongue rail is excessively displaced by impact force generated between the railway vehicle passing through the turnout and the rail and exceeds the elastic limit.

[0019] In an embodiment of the present invention, the reinforcing device (300) is characterized by being composed of a first groove that accommodates the bottom of the tongue rail (200) and a side that contacts the belly of the tongue rail (200), thereby restricting the tongue rail (200) from moving toward the base rail (100) due to an impact force applied to the tongue rail (200).

[0020] In an embodiment of the present invention, a plurality of replaceable elastic bodies (310) are installed at the side end of the reinforcing device (300).

[0021] In an embodiment of the present invention, the stopper (500) is characterized by being replaceable and insertable into one of the plurality of grooves according to the amount of displacement of the tongue rail (200).

[0036] Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.

[0037] The parts necessary to understand the operation and function according to the present invention will be explained in detail, focusing on the parts necessary for understanding.

[0038] In describing the embodiments of the present invention, explanations of technical details that are well known in the technical field to which the present invention belongs and are not directly related to the present invention are omitted.

[0039] This is intended to convey the essence of the invention more clearly without obscuring it by omitting unnecessary explanations.

[0040] In addition, when describing the components of the present invention, different reference numerals may be assigned to components with the same name depending on the drawing, and the same reference numeral may be assigned even to different drawings.

[0041] However, even in such cases, it does not mean that the component has different functions depending on the embodiment or has the same function in different embodiments, and the function of each component should be determined based on the description of each component in the respective embodiment.

[0042] Furthermore, technical terms used in this specification shall be interpreted in the sense generally understood by those skilled in the art to which the present invention pertains, unless specifically defined otherwise in this specification, and shall not be interpreted in an overly broad or overly narrow sense.

[0043] Additionally, singular expressions used in this specification include plural expressions unless the context otherwise indicates.

[0044] In this application, terms such as "composed" or "comprising" should not be interpreted as necessarily including all of the various components or steps described in the specification, and should be interpreted as potentially excluding some of the components or steps, or including additional components or steps.

[0045] As shown in FIG. 1, the existing turnout point section generally has a form in which the tongue rail moves along the upper plate sliding surface in accordance with the operation of the turnout, but a problem has occurred in which the tongue rail moves beyond the allowable amount of movement due to the impact of the railway vehicle running on the tongue rail or the base rail.

[0046] FIG. 2 illustrates a system diagram of a branch point section according to a first embodiment of the present invention.

[0047] First, the lower plate (920) in contact with the sleeper is fixed at both ends by a first fastener (810) that penetrates the lower plate and the sleeper.

[0048] The first fasteners mentioned above may be arranged in multiple numbers on the side of the lower plate (920).

[0049] One side of the base rail (100) is fixed to a first clip (600) that is installed by passing through a first clip fixing member (700) fixed to one side of the lower plate (920).

[0050] The lower plate (920) is fixedly coupled to the upper plate (910) at the top, and one end of an elastic clip penetrating the lower part of the upper plate (910) comes into contact with the other lower part of the base rail (100) to fix the base rail (100) to the lower plate.

[0051] A tongue rail (200) is positioned on the upper plate (910), and a reinforcing device (300) that restricts further movement toward the base rail (100) beyond the allowable displacement for the tongue rail (200) to move for the branching operation of the turnout is positioned on one side of the upper plate (910) and is fixed by a second fastening member (820).

[0052] The first groove formed in the lower part of the reinforcing device (300) accommodates the lower part of the tongue rail (200) to restrict the tongue rail (200) from vibrating or moving up and down or left and right according to the impact force of the railway vehicle applied to the turnout, and the side of the reinforcing device (300) supports the abdomen of the tongue rail (200) to restrict lateral movement of the tongue rail (200) beyond the allowable displacement.

[0053] At this time, a detachable elastic body (310) is installed on the side of the reinforcing device (300) to prevent damage caused by displacement due to collision of the tongue rail (200), and also to significantly reduce noise caused by collision between the reinforcing device (300) and the tongue rail (200).

[0054] On the other side of the tongue rail (200), a stopper (500) is inserted into and fixed in a groove formed in the upper plate (910), and the groove may be formed in multiple places in the upper plate (910).

[0055] The stopper (500) can be inserted into the plurality of groove positions by adjusting it, taking into account the operating range of the tongue rail (200), which can be changed according to the specifications of the turnout.

[0056] The primary function of the stopper (500) is to restrict the movement of the tongue rail (200) so that it does not move away from the upper plate (910) due to the impact force of the railway vehicle applied to the turnout.

[0057] In addition, a secondary function is to create a barrier that can prevent abnormal lateral displacement of the tongue rail (200) by inserting and fixing a plurality of the stoppers into the plurality of grooves, thereby preventing it first and, if necessary, secondarily.

[0058] Figure 3 illustrates the appearance of the top plate (900).

[0059] The elastic clip is inserted through the elastic clip groove (400), and a plurality of first fastening holes, through which the first fastening member (810) passes to be combined with the sleeper, may be located at the end of the top plate.

[0060] In addition, the first fastening member (810) is fastened by penetrating the lower plate (920), and measures are taken to increase the fastening force by placing a spring, nut, etc., in the middle.

[0061] At both ends of the upper plate (910), a second fastening hole is formed as a crescent shape at one end of the second fastening hole, where a second fastening member (820) for fixing the reinforcing device (300) to the upper plate (900) is located, so that maintenance can be performed without completely releasing the second fastening member (820) to move the reinforcing device (300) in the longitudinal direction in case of emergency.

[0062] The above stopper (500) can be fixed by welding, adhesive, or a separate dedicated fastener, etc., depending on the situation after being inserted into the groove.

[0063] The above fixing method can be selected by the track maintenance manager as needed, depending on the track operation conditions.

[0064] FIG. 4 shows a perspective view of the reinforcing device (300) above.

[0065] Since the above reinforcing device (300) is configured to receive strong external forces due to frequent collisions or friction with the tongue rail, a rib is provided on one side to maintain the necessary rigidity.

[0066] FIG. 5 illustrates a layout system for branch point sections according to the first embodiment of the present invention.

[0067] When the tongue rail (200) moves in the direction of the base rail (100) for railway vehicle branching, as described above, the lower part of the tongue rail (200) engages with the first groove at the bottom of the reinforcing device (300), thereby limiting vertical displacement along with lateral displacement.

[0068] The above function also functions when the tongue rail (200) is laterally displaced in the opposite direction.

[0069] That is, even if the tongue rail (200) moves toward the stopper (500), the lower part of the tongue rail (200) is still located in the lower groove of the reinforcing device (300), so that even if the stopper (500) limits lateral displacement exceeding the limiting displacement, the lower groove of the reinforcing device (300) can still limit vertical displacement.

[0070] Therefore, if the width of the lateral displacement of the tongue rail (200) increases according to the specifications of the turnout, the lower groove of the reinforcing device (300) can also be positioned accordingly.

[0071] Additionally, the illustrated stopper (500) is configured to simply limit the lateral displacement of the tongue rail (200), but a second groove may be formed to accommodate the tongue rail elastic part (210), such as the first groove at the bottom of the reinforcing device (300).

[0072] FIG. 6 illustrates a layout system for branch point sections according to a second embodiment of the present invention.

[0073] The reinforcing device (300) is fixed by a second clip (620) penetrating a second clip fixing member (720) fixed to one side of the upper plate (910), and the second clip is fixed to the upper plate (900) in a double manner by a second fastening member (820).

[0074] Since the above reinforcing device (500) may be displaced from its position due to lateral displacement of the tongue rail (200) as well as irregular and repetitive impact forces caused by railway vehicles passing through the turnout, the second fastening member and the second clip are used simultaneously to maximize the fastening force.

[0075] In this case, even if the second clip and second fastener used in Fig. 6 are not used, various fasteners and fixing devices may be used depending on the track conditions.

[0076] FIG. 7 illustrates an elastic body (310) that is detachably attached to a side end of a reinforcing device (310).

[0077] The above elastic body (310) is used to prevent the tongue rail (200) from vibrating due to kinetic energy transmitted from a train passing through the turnout at high speed, thereby preventing the accumulation of impact force in the reinforcing device (300).

[0078] The reinforcing device (300) serves to limit the tongue rail (200) from moving excessively toward the base rail (100), but if the impact force continues to accumulate, it may cause rupture, wear, or the generation of unnecessary dust and noise.

[0079] In addition, as shown in FIGS. 5 to 7, the reinforcing device (300) is cross-fastened to the lower plate (920) by means of fastening devices (clips, fixing devices, fasteners, etc.). Therefore, it is obvious that if the reinforcing device (300) is damaged, it will take a long time to dismantle the multiple fastening devices, install the reinforcing device (300) with weight, and then re-fasten it.

[0080] Since the disassembly and assembly of the aforementioned fastening device involves multiple components and a complex fastening mechanism, making maintenance automation difficult, track managers must perform maintenance manually one by one, so it is necessary to extend the maintenance cycle as much as possible.

[0081] The above elastic body (310) is installed for the purpose of cushioning the impact force between the reinforcing device (300) and the tongue rail (200) to limit damage to the tongue rail (200) and the reinforcing device (300), while also preventing anti-environmental elements such as dust and noise caused by collision between the two components.

[0082] The elastic body (310) can be fixed to the side end of the reinforcing device (300) with adhesive. This is because if the elastic body (310) is fixed with a separate fastener such as a bolt, the fastener may cause direct damage to the tongue rail (200), and it is difficult to check the extent of damage to the elastic body (310) from the outside.

[0083] Maintenance is made easier because the track manager only needs to perform maintenance when visually confirming that the elastic body (310) has detached from the reinforcing device (300). In particular, maintenance time can also be reduced because the elastic body (310) can be attached to the reinforcing device (300) simply with adhesive without a separate fastening tool.

[0084] As an embodiment of the present invention, the elastic body (310) may be composed of a coating surface (320) on which an adhesive is applied and a cover surface (330) that prevents the coating surface (320) from being exposed to external foreign substances.

[0085] After the track manager checks whether the elastic body (310) attached to the reinforcing device (300) has fallen off through visual inspection, if there is a damaged elastic body (310), the cover surface (330) sealing the coating surface (320) of the elastic body (310) at that location is removed, and the elastic body (310) is attached to the side end of the reinforcing device (300), thereby completing the maintenance work.

[0086] Since the purpose of the above elastic body (310) is to mitigate the impact force between the reinforcing device (300) and the tongue rail (200), there are no restrictions on its shape. However, if it has a shape that is symmetrical in the length and height directions relative to the base rail (100), such as a circle or a square as shown in FIG. 8, the track manager can reduce the time required to align the elastic body (310) when attaching it to the reinforcing device (300).

[0087] In addition, the width of the bottom portion can be made narrower than the width of the entrance of the groove formed in the upper plate (910) so that the stopper (500) is not easily separated when attached to the groove.

[0088] The stopper (500) fitted into the above groove may be fixed by the elastic force of the upper plate (910) and the stopper (500) as in the above embodiment, or it may be fixed by a commercial method such as a bolt / nut or a fastener, although not specified in the drawing.
