[0003] Statement regarding federally sponsored research and development

[0004] not applicable. Background Technology

[0005] Railcars or trains typically travel on tracks. During their journey, under certain circumstances, railcars or trains can switch from one track to another. Summary of the Invention

[0006] This disclosure provides a rail switch system and method. Specifically, it provides a system and method for using a rail switch designed to provide temporary or permanent railway switches, allowing for rapid, unrestricted switching without the need to cut into existing tracks. Moreover, because the rail switch does not require cutting into existing tracks, it is more cost-effective, does not require interruption of main track installation, and can be used in applications where conventional switching methods might be too expensive (e.g., as a mainline switch for smaller or infrequently loaded industries, as a short rail to reopen industrial tracks where switches were previously removed, or for temporary access to project sites or temporary storage of train cars). When not in use, the switch can be completely separated from the mainline. The design of the rail switch allows for assembly in various configurations to suit specific applications to connect any two tracks, for example, tracks with different vertical or horizontal geometries, longitudinal gradients, slopes, or any combination thereof.

[0007] In some aspects, this disclosure provides a railway turnout comprising a turnout section, one or more track sections joined together to form a single track, and a pair of ramp sections joined to opposite ends of the single track. One of the track sections is rotatably coupled to the turnout section to allow the ramp sections to rotate relative to the turnout section and selectively connect a first railway track to a second railway track.

[0008] The turntable section includes a ballast frame, a bearing base plate connected to a pivot pin, and a bearing plate. The ballast frame further includes two longitudinal members connected by a plurality of generally perpendicular transverse members and connected to the bearing base plate, such that the pivot pin extends upward away from the ballast frame. The bearing plate defines a central bore through which the pivot pin extends, thereby allowing the bearing plate to rotate about the central axis of the pivot pin.

[0009] Each of the one or more track segments further includes a track base, coupled to a track running longitudinally along the track base. A track base plate defines a hole configured to pass through it to receive a pivot pin, providing a rotatable connection around the pivot pin. The hole in the track base plate may be generally positioned at the center of the track base plate. Furthermore, the track base plate is configured to be fixedly coupled to a connecting plate at each end of the track base plate. A corresponding number of connecting plates are provided for connection between each track segment. The length and curvature of the one or more track segments may both differ.

[0010] Each of the two ramp sections includes a ramp base plate, an angled track, at least two guard rails, and at least two track clamps. The ramp base plate is configured to sit on top of one of the first and second railway tracks. Pairs of track stops may be attached to the underside of the ramp base plate to align the ramp section with either the first or second railway track. The ramp base plate also includes a ramp section located at a first distal end. Additionally, the ramp base plate is configured to be fixedly connected to a connecting plate at a second distal end opposite the ramp section, wherein the connection is configured to connect the ramp section and the track section.

[0011] The angled track begins at the generally pointed end of the adjacent slope section, slopes substantially upward along the length of the slope section, and terminates at the wide end of the second distal end, which is adjacent to the first distal end.

[0012] At least two protective rails extend parallel to the angled rail. The at least two protective rails can be configured such that at least two protective rails are arranged inside the angled rail, or at least two protective rails are arranged outside the angled rail.

[0013] At least two protective rail clamps are coupled to a ramp base plate at a locking pivot and configured to provide a removable connection to an existing rail. Each of the at least two rail clamps includes a pivot rod fixedly coupled to the locking pivot, a handle configured to be rotatably coupled to the pivot rod, and one or more locking plates having a channel configured to receive a first or second rail. The handle and the one or more locking plates are fixedly coupled such that the handle and the one or more locking plates are rotated together about the pivot rod between an unlocked position away from the rail and a locked position in which the channel of the one or more locking plates is coupled to the rail.

[0014] The track switch further includes one or more support frames configured between one or more track sections and the ground to provide support to the track sections. Each support frame includes two longitudinal members connected by a plurality of substantially vertical transverse members.

[0015] The rail turnout may further include an actuator system for rotating the turnout, such as a hydraulic actuator. The rail turnout may include at least one first actuator connecting bracket coupled to one of the track sections. Additionally, one or more corresponding second actuator connecting brackets may be provided at the turntable section to connect the actuator system between the track section and the turntable section. Alternatively, one or more corresponding second actuator connecting brackets may be disposed on a support frame to connect the actuator system between the track section and the support frame.

[0016] In some aspects, this disclosure provides a method for selectively connecting a track turnout to a railway track, the method comprising connecting a plurality of track sections together to form a single track, connecting a ramp section to each end of the single track, connecting a turntable section to one of the plurality of track sections to rotate the ramp section relative to the turntable section, and rotating the single track from a closed position where the ramp section is misaligned with the existing track to an open position where the ramp section is aligned with the existing track.

[0046] The invention will now be described in more detail with reference to the following non-limiting examples. It should be noted that the following embodiments are presented herein for illustrative purposes only and are not intended to be exhaustive or limited to the specific forms disclosed.

[0047] It should be understood that the wording and terminology used herein are for descriptive purposes and should not be considered limiting. The terms “comprising,” “including,” and “having,” and their variations, as used herein, mean that they cover the items listed thereafter, their equivalents, and any additional items. Unless explicitly stated or otherwise defined, the terms “installation,” “connection,” “support,” and “linkage,” and their variations, are used broadly to cover direct and indirect installation, connection, support, and linking. Furthermore, “connection” and “linkage” are not limited to physical or mechanical connections or links.

[0048] Track switches are typically used to allow train cars to change tracks, for example, to bypass a section of a main railway line undergoing maintenance, to store cars on short rails, or as a branch line to transport goods away from the main line. However, existing track switches have many drawbacks. For example, installing existing switches requires cutting into the main rail, resulting in long installation times, disruption of main rail availability, increased maintenance, and high costs. Due to these disadvantages, traditional switching methods are often permanent and generally not cost-effective for smaller industries or infrequently used tracks.

[0049] Figure 1A non-limiting example of a track turnout 10 according to various aspects of this disclosure is shown. The track turnout 10 includes a turntable section 12, one or more track sections 14 with different lengths and curvatures, and a pair of ramp sections 16. Each ramp section 16 may include a pair of laterally opposed track clamps 17, which allow the track turnout 10 to be selectively coupled to existing railway tracks.

[0050] Track section 14 and ramp section 16 are connected to each other to form and serve as a single track line, thereby allowing, for example, a railcar or locomotive to travel across the track switch 10. Turntable section 12 is configured to connect with one of the track sections 14, forming a rotatable connection. This connection allows track section 14 and ramp section 16 to rotate relative to turntable section 12 between a closed position and an open position.

[0051] In addition, multiple support frames 18 may be positioned substantially adjacent to and / or below the track turnout 10. The support frames 18 can provide vertical support and a stable base for the track section 14. The number and location of the support frames 18 may vary depending on specific installation requirements, including but not limited to soil conditions and type, drainage requirements, the length and shape of the track section 14 in use, and the distance between the railway sections that the track turnout 10 is intended to connect to.

[0052] Figure 2 Another non-limiting example of a rail switch 10 according to various aspects of the present disclosure is shown. In the illustrated non-limiting example, the rail switch 10 includes an actuator bracket 22 attached to the side of a turntable section 12. An actuator 24 (e.g., a hydraulic actuator) may be connected between the actuator bracket 22 and one of the track sections 14. Specifically, the actuator 24 may be connected between the turntable section 12 and the track section 14 connected to the turntable section 12. In this way, for example, the actuator 24 is configured to selectively rotate the rail switch 10 between an open position and a closed position. In the illustrated non-limiting example, the actuator 24 is arranged on a common side of the turntable section 12. In other non-limiting examples, the actuator 24 may be arranged on laterally opposite sides of the turntable section 12 (see [link to relevant documentation]). Figure 4 In the non-limiting example illustrated, one of the actuators 24 may push (e.g., extend) the track segment 14 connected to it, and another actuator 24 may pull (e.g., retract) the track segment 14 during rotation of the track switch 10.

[0053] Figure 3Another non-limiting example of a track switch 10 according to various aspects of this disclosure is shown. In the illustrated non-limiting example, the track switch 10 includes track connecting brackets 26 at each intersection between track segments 14 and between track segments 14 and ramp segments 16. The track connecting brackets 26 may be configured to securely connect the track segments 14 and ramp segments 16 together to form a single track. In other non-limiting examples, the track segments 14 and ramp segments 16 may be connected to each other via interlocking features present on these segments themselves.

[0054] In the illustrated non-limiting example, actuator bracket 27 is coupled to one of the support frames 18. Actuator bracket 27 houses actuator 25, which can be coupled to one of the track sections 14. The track switch 10 arranged in this way can rotate around turntable section 12, between a closed position and an open position, by extending or retracting the actuator 25.

[0055] Generally, various components of the turnout 10 can be customized to suit specific railway applications. For example, the arrangement of the turnout section 12 can vary along the turnout 10 to change the location of the pivot point defined by the turnout. For example, in some non-limiting examples, the turnout section 12 can be arranged substantially adjacent to the longitudinal center of the turnout (e.g., see...). Figure 1 , 2 (4, 5). Alternatively, the turntable section 12 can be arranged approximately at one end of the track turnout (e.g., see...). Figure 3 , 6 7) Proximity (e.g., proximity to one of the ramp sections 16). One or more actuators may be coupled to a corresponding number of track sections such that the switch 10 can rotate as long as the actuators are arranged at a certain distance from the pivot point. It should be understood that in some non-limiting examples, the switch 10 can be rotated by external components not directly coupled to the switch. That is, the switch 10 may not include actuators coupled to the track sections (e.g., see...). Figure 1 Furthermore, the track switch 10 can be selectively rotated by an external device (e.g., off-highway vehicle or forklift).

[0056] Figure 4 Another non-limiting example of a track switch 10 in the open position according to several aspects of this disclosure is shown. In the illustrated non-limiting example, the turntable section 12 includes two actuators 24 coupled to its laterally opposite sides. In this non-limiting example, both actuators 24 can extend to move the track switch 10 from the closed position (see [link to diagram]). Figure 5 Rotate to the open position. Figure 4 Either the actuator 24 or the actuator 24 can retract to move the track switch 10 from the open position. Figure 4Rotate to the closed position. Figure 5 ).

[0057] In the open position, the switch 10 rotates such that ramp section 16 aligns with the first existing track 28 and the second existing track 29, providing a path between them. That is, ramp section 16 can be rotated to the open position, where ramp section 16 is aligned with the first existing track 28 and the second existing track 29. When one ramp section 16 is aligned with the first existing track 28 and the other ramp section 16 is aligned with the second existing track 29, a railcar or locomotive can travel along the first existing track 28, cross the switch 10, and proceed onto the second existing track 29, or vice versa. In this way, the railcar or train will travel onto ramp section 16, cross each track section 14, and finally exit the other ramp section 16. Additionally, when in the open position, each rail clamp 17 is engaged with the corresponding first existing track 28 and second existing track 29, thereby preventing the switch 10 from rotating out of the open position.

[0058] Figure 5 Showing the closed position Figure 4 The track switch 10. In the closed position, each track clamp 17 is disengaged from the first existing track 28 and the second existing track 29. With the track clamps 17 disengaged, the track switch 10 and the ramp section 16 can rotate away from both the first existing track 28 and the second existing track 29, so that the ramp section 16 is not aligned with or overlaps with the first existing track 28 and the second existing track 29. Due to the misaligned and non-overlapping arrangement between the ramp section 16 and the first existing track 28 and the second existing track 29, railcars or locomotives or other objects traveling on the railway will not be able to cross the track switch 10. That is, the track switch 10 does not change its travel along the first existing track 28 and the second existing track 29 in the closed position. Therefore, railcars or locomotives traveling on the first existing track 28 or the second existing track 29 will be able to continue traveling unimpeded along the corresponding track.

[0059] about Figure 4 and Figure 5 Ideally, a sufficient number of support frames 18 should be used, arranged to ensure that all track sections 14 and ramp sections 16 are supported. For example, one or more support frames 18 may be arranged between the first track section 28 and the second track section 29 to provide support for the track section 14 that is not supported by the turntable section 12, and for the ramp section 16 when the track switch is in the closed position.

[0060] Figure 6Another rail switch 10 according to several aspects of this disclosure is shown in the open position. In the open position, the rail switch 10 and ramp section 16 are rotated so that ramp section 16 is aligned with and rests on the first existing track 28 and the second existing track 29. When one of the ramp sections 16 is aligned with the first existing track 28 and the other ramp section 16 is aligned with the second existing track 29, a railcar or locomotive can travel along the first existing track 28, cross the rail switch 10, and proceed parallel to the second existing track 29, or vice versa. In this way, the railcar or train will travel onto the ramp section 16, cross the respective track sections 14, and finally leave the other ramp section 16. Furthermore, when in the open position, each rail clamp 17 is engaged with the corresponding track 28, thereby preventing the rail switch 10 from rotating out of the open position.

[0061] In the non-limiting example illustrated, the pivot point is defined as one of the adjacent ramp sections 16 at the location of the turnout section 12 along the track switch 10 (e.g., from...). Figure 6 and 7 From the perspective of the angle, it is arranged as the right ramp section 16. The track turnout 10 and the ramp section 16 can be rotated between the open and closed positions by an external device. Figure 7 The external device is configured to provide force on one of the track sections 14 and rotate the ramp section 16 about a pivot point in the turntable section 16. Alternatively or additionally, the track switch may include one or more actuators as described herein to selectively rotate the ramp section 16 between an open position and a closed position.

[0062] Figure 7 Showing the closed position Figure 6 An example of a track switch 10. In the closed position, each track clamp 17 is disengaged from the first existing track 28 and the second existing track 29. With the track clamps 17 disengaged, the track switch 10 and the ramp section 16 can rotate away from one or more of the first existing track 28 and the second existing track 29, such that the ramp section 16 is not aligned with or overlaps with the first existing track 28 and / or the second existing track 29. Due to the misaligned and non-overlapping arrangement between the ramp section 16 and the first existing track 28 and / or the second existing track 29, railcars or locomotives or other objects traveling on the railway will not be able to cross over the track switch 10.

[0063] In this specific, non-limiting example, the track switch 10 is completely separated from the second existing track 29, while one of the ramp sections 16 remains in an overlapping but misaligned arrangement with the first existing track 28. Therefore, when the track switch is in the closed position, a railcar or locomotive will be able to travel on the second existing track 29.

[0064] Figure 8 and Figure 9 A turntable section 12 is shown as an example of several aspects of this disclosure. The turntable section 12 includes a ballast frame (ballast rack) 30, a bearing base plate 36, a pivot pin 38, and a bearing plate 40. The ballast frame 30 has at least two longitudinal members 32 connected by a plurality of transverse members 34. Depending on the desired configuration, the bearing base plate 36 may include one or more separate plates.

[0065] The ballast frame 30 defines a bottom portion 42 configured to rest on the ground and a top portion 44 configured to connect to and support the bearing base plate 36. In addition, the ballast frame 30 may include various attachment points or lifting points 46 for moving, transporting or installing the turntable section 12.

[0066] The pivot pin 38 is connected to the bearing base plate 36 and extends upward. The bearing plate 40 defines a hole 46 for receiving the pivot pin 38, thereby forming a rotatable connection (part) that allows the bearing plate 40 to rotate relative to the bearing base plate 36 and the ballast frame 30. The bearing plate 40 can have various shapes, but is preferably circular, and may include recesses 48 on its outer periphery. The recesses 48 can be used to assist in positioning the track switch 10 in the open or closed position. The bearing plate 40 is supported by the bearing base plate 36.

[0067] The turntable section also includes actuator brackets 22 attached to the ballast frame 30. Here, two actuator brackets 22 are connected to the same longitudinal member 32 on one side of the frame 30. However, the number and position of the actuator brackets 22 can vary depending on the construction of the turnout 10 used. For example, in some cases, there may be no actuator brackets 22, or there may be only one. Furthermore, when using multiple brackets 22, the brackets 22 do not need to be located on the same side of the ballast frame 30, but can be located on different longitudinal members 32, such that the brackets 22 are arranged on opposite sides of the ballast frame 30.

[0068] Figure 10 and 11 An example bearing plate 40 according to several aspects of this disclosure is shown. The bearing plate 40 is generally circular in shape and includes a central hole 46 configured to receive a pivot pin 38 of a turntable segment 12. A rotatable connection is formed by inserting the pivot pin 38 into the hole 46, which allows the bearing plate 40 to rotate about the pivot pin 38. When the pivot pin 38 is received by the hole 46, the bearing plate 40 is positioned adjacent to the bearing base plate 36. It should be noted that oil, grease, or other lubricants may be placed between the bearing plate 40 and the bearing base plate 36 to reduce friction during rotation of the bearing plate 40.

[0069] The bearing plate 40 may also include various recesses 48 disposed around the outer periphery of the bearing plate 40. In this case, there are four recesses 48, however, there may be more or fewer. Furthermore, although the recesses 48 shown herein are semi-circular in shape, the recesses 48 may take various shapes depending on the application requirements.

[0070] It should be understood and recognized that, as will become apparent in this disclosure, track segments 14 do not need to be of a single length or shape. Rather, some track segments 14 may be considered long, while others may be relatively short. Furthermore, some track segments 14 may be straight, while others may be curved. The number, length, and curvature of the track segments 14 used will be determined by the specific application of the track switch 10 and the existing track segments selectively connected by the track switch 10.

[0071] Reference Figure 12 and Figure 13 An example of a track segment 14 according to several aspects of the present disclosure is shown. The track segment 14 includes a track substrate 50 and a track 52. The track substrate 50 defines a bottom surface 54, a top surface 56, two sides 58 and 59, and a first distal end 60 and a second distal end 61. The track substrate 50 is a generally longitudinally oriented plate having a hole 62 extending through the track substrate 50.

[0072] Hole 62 is configured to receive the pivot pin 38 of turntable segment 12, establishing a rotatable connection between track segment 14 and turntable segment 12 around pivot pin 38. When hole 62 of track base plate 50 receives pivot pin 38, bottom surface 54 of track base plate 50 is configured adjacent to bearing plate 40 of turntable segment 12. While multiple track segments 14 capable of receiving pivot pin 38 can be used, only one of track segments 14 receives pivot pin 38. Therefore, track segments 14 in a given assembly of turnout 10 can be assembled in a modular manner, and the pivot point can be determined by the position of turntable segment 12 and the specific track segment 14 receiving pivot pin 38. In some non-limiting examples, some track segments 14 may include hole 62, while others may not, provided that one of the track segments 14 is capable of receiving pivot pin 38.

[0073] Although the hole 62 shown here is generally positioned at the center of the track base plate 50, the hole 62 can be placed anywhere on the track base plate 50. By positioning the hole 62, for example, closer to the distal end 60, the rotation center of the track switch 10 can be adjusted to suit the specific application of the track switch 10.

[0074] The track 52 is configured to allow, for example, a railcar or locomotive to travel along the track 52. The track 52 is fixedly connected to the top surface 56 of the track base plate 50 and extends along the length of the track base plate 50 from one distal end 60 to the second distal end 61 of the track base plate 50.

[0075] The distal ends 60 and 61 of the track base plate 50 are each configured to connect and align with the distal end 60 or 61 of another track base plate 50 or ramp segment 16. As shown, threaded holes 64 are disposed in the track base plate 50, adjacent to each distal end 60 and 61 of the track base plate 50. The threaded holes 64 may be configured to align with corresponding holes 65 in the track connection bracket 26 (see Figure 1). Figure 17 When hole 64 is aligned with hole 65 of track connecting bracket 26, track segment 14 can be connected to another track segment 14 via track connecting bracket 26 and a plurality of fasteners. However, other methods can also be used to connect track segments 14, such as by fasteners alone, by welding adjacent track segments 14 together, or by using an interlocking connector configured to connect the tracks without the use of additional hardware.

[0076] Additionally, track segment 50 may include offset alignment rods 66 configured to aid in aligning adjacent track segments 50 such that corresponding tracks 52 are linearly aligned with each other. In some non-limiting examples, track segment 14 may include multiple attachment or lifting points 68 for moving, transporting, or installing track segment 14.

[0077] Reference Figure 14 and Figure 15 The following diagram illustrates other examples of track section 14 according to several aspects of this disclosure. In this embodiment, track section 14 is a curved longitudinal member. The track 52 is configured to have a curvature corresponding to the curvature of the track base plate 50. The curvature of track section 14 can be varied as needed to allow the track switch 10 to be connected to various existing railway tracks 28.

[0078] Generally, the lengths and curvatures of the multiple track segments 14 can vary, as shown herein, to provide a single track extending between the ramp segments 16. Therefore, the track segments 14 can be customized to fit a specific existing track layout and / or a specific distance between existing tracks.

[0079] Figure 16An example track section 14 connected to the turntable section 12 is shown. In the illustrated non-limiting example, a pivot pin 38 is received by a hole 62 in the track section 14. An actuator 24 is connected to both the actuator bracket 22 and the track section 14. The track section 14 is connected to the actuator 24 at the bracket 70. In this arrangement, the actuator 24 is configured to extend and retract to allow the track section 14 to rotate, thereby allowing the ramp section 16 to rotate between an open position and a closed position.

[0080] Figure 17 An example track connection bracket 26 is shown according to several aspects of this disclosure. The track connection bracket 26 defines holes 65 corresponding to holes 64 in the track segments 14. When the holes 65 are aligned with the holes 64 in the track segments 14, fasteners can be inserted into the corresponding holes 64 and 65 to connect the track connection bracket 26 to two track segments 14, or to connect the track segments 14 to the ramp segments 16 (see...). Figure 3 ).

[0081] Figure 18-25 An example ramp section 16 according to several aspects of this disclosure is shown. The ramp section 16 includes a ramp base plate 74, an inclined track 75, a guard track 76, and a pair of track clamps 17. The ramp base plate 74 includes a bottom surface 77 and a top surface 78 configured to rest on top of the rail 28, a first distal end 79 and a second distal end 80 each configured to connect to the track section 14, and two sides 81 and 82 (see...). Figure 21-22 The bottom surface 77 of the ramp base plate 74 may also include a ramp stop 83 attached to the bottom surface 77 to assist in aligning the ramp section 16 on the railway track 28.

[0082] For details, please refer to the following: Figure 21-23 The ramp base plate 74 further defines a ramp portion 84 at the first distal end 79, which extends from a generally pointed region 85 closest to the first distal end 79 and the bottom surface 77. The ramp portion 84 is angled upwards with respect to the top surface 78 in the direction of the second distal end 80. The top surface 78 of the ramp base plate 74 can be connected to a lifting point 86 to facilitate movement of the ramp section 16 during transport or installation.

[0083] The ramp track 75 comprises two parallel ramp tracks, each defining a bottom surface 87 and an inclined top surface 88, forming a generally pointed end 89 and a wide end 90 (see...). Figure 24 and 25 The angle of the inclined top surface 88 corresponds to the angle of the ramp portion 84 of the ramp base plate 74. The ramp track 75 is connected to the ramp base plate 74 such that the bottom surface 87 of the ramp track 75 contacts the top surface 78 of the ramp base plate 74.

[0084] The ramp track 75 is oriented such that its pointed end 89 is disposed adjacent to the ramp portion 84 of the ramp base plate 74. The ramp track 75 extends along the length of the ramp base plate 74 toward the second distal end 80 of the ramp base plate 74. Oriented in this way, the ramp portion 84 of the ramp base plate 74 and the inclined top surface 88 of the ramp track 75 form a generally continuous upward slope that begins at the first distal end 79 of the ramp base plate 74 and terminates at the second distal end 80.

[0085] The protective rail 76 extends parallel to the ramp rail 75. In this case, there are four protective rails 75, two of which are arranged inside the rail 75 and two of which are arranged outside the rail 75, adjacent to the sides 81 and 82. However, fewer than four protective rails 75 can be used; for example, there can be only two protective rails 75, both of which are arranged inside the rail 75.

[0086] Each protective rail 76 includes a bottom surface 91 that engages with the top surface 78 of the ramp base plate 74, and an inclined top surface 92 that corresponds to the inclined top surface 88 of the ramp rail 75, such that the top surface 88 of the ramp rail 75 and the top surface 92 of the protective rail 76 are substantially aligned. In some embodiments, the top surface 92 of the protective rail 76 may be higher or lower than the inclined top surface 88 of the ramp rail 75. The protective rail 76 may also include braces, struts, or other support structures to provide additional strength and stiffness. Each of the pair of rail clamps 17 is attached to a corresponding side 81 and 82 of the ramp base plate 74 at a pivot locking bracket 93 engaged with the ramp base plate 74.

[0087] Figure 26 An example track clamp 17 according to several aspects of this disclosure is shown. The track clamp 17 includes a pivot rod 94, a handle 95, and one or more locking plates 96. The pivot rod 94 is a cylindrical rod configured to be fixedly coupled to a pivot locking bracket 93 and extends parallel to both sides of a ramp base plate 74. The handle 95 is configured to receive the pivot rod 95, thereby allowing the handle 95 to rotate about the pivot rod 94.

[0088] Each locking plate 96 is fixedly connected to a handle 95 and defines a hole 97 through which a pivot rod 94 extends. Each locking plate 96 defines a channel 98 configured to receive and connect to the railway track 28. The handle 95 and one or more locking plates 96, as a single unit, rotate about the pivot rod 94 between an unlocked position and a locked position. In the unlocked position, the track clamp 17 is not in contact with the existing track, while in the locked position, the channel 97 of one or more locking plates 96 engages with the existing track, thereby securely connecting the ramp section 16 to the railway track 28.

[0089] Figure 27An example support frame 18 is shown according to several aspects of this disclosure. The support frame 18 has two longitudinal members 98 connected by a plurality of transverse members 99. The support frame 18 defines a bottom portion 100 near the longitudinal members 98, configured to provide a stable connection to the ground. The support frame 18 further defines a top portion 101 adjacent to the transverse members 99, configured to provide support to the bottom surface 54 of the track base plate 50 or the bottom surface 77 of the ramp base plate 74, thereby providing vertical support to the track section 14 and the ramp section 16. Furthermore, depending on the configuration of the track turnout 10, the support frame 18 may also include attachment brackets 22 and / or lifting points 102 for the actuator system 24 (e.g., a hydraulic actuator) to facilitate movement of the support frame 18 during transport and installation.

[0090] It should be understood and recognized that any number or configuration of support frames 18 may be used depending on the requirements of the specific application. Any support frame 18 is preferably arranged to provide support to the various track sections 14 and ramp sections 16 of the turnout 10, such that the turnout 10 is fully supported anywhere between the open and closed positions.
