Description

Technical Field

[0001] Embodiments of this application relate to the field of locking mechanisms for turnouts, and more specifically to a connecting rod assembly suitable for steel turnout sleepers. Background Technology

[0002] The statements herein are provided merely as background information in connection with this application and do not necessarily constitute prior art.

[0003] A railway switch machine is the actuator of a railway turnout control system, used for switching, locking, and monitoring the current position of the turnout. In a switch machine, two indicator rods (locking rods) are each connected to a switch rail via indicator connecting rods. When the switch machine's actuating rod moves the switch rail, the switch rail moves the indicator connecting rod, which in turn moves the indicator rods (locking rods), allowing the moving contact to swing and contact the stationary contact. This enables the switch machine to indicate the current state of the turnout.

[0004] Currently, the structure of the connecting rod still has limitations. Summary of the Invention

[0005] A brief overview of this application is provided below to offer a basic understanding of certain aspects thereof. It should be understood that this overview is not an exhaustive summary of the application. It is not intended to identify key or essential parts of the application, nor is it intended to limit its scope. Its purpose is merely to present certain concepts in a simplified form as a prelude to the more detailed description that follows.

[0006] To address the aforementioned problems, embodiments of this application provide a indicating connecting rod assembly suitable for steel turnout sleepers, used to connect a switch machine and a switch rail. The indicating connecting rod assembly includes a switch machine connector, a switch rail connector, and an insulating connector. The switch machine connector is used for detachable connection to the switch machine's rod joint, the switch rail connector is used for detachable connection to the switch rail, and the insulating connector is used to detachably and insulately connect the switch machine connector and the switch rail connector.

[0007] The indicator connecting rod assembly provided in the embodiments of this application detachably connects the switch machine connector and the switch rail connector via an insulating connector. This allows the indicator connecting rod assembly to have a suitable length by selecting an insulating connector of appropriate length, while maintaining the same size and shape of the switch machine connector and the switch rail connector. This allows it to connect the switch machine's indicator rod (locking rod) to the switch rail at the appropriate distance. Indicator connecting rod assemblies of different lengths can have switch machine connectors and switch rail connectors of the same size and shape, thereby improving the versatility of the indicator connecting rod assembly.

[0008] Furthermore, since the length of the connecting rod assembly is usually quite long (approximately 2m), the switch machine connector and the switch rail connector can be detachably connected by an insulating connector, which allows the switch machine connector, switch rail connector, and insulating connector to be processed separately, thus reducing the processing difficulty of the connecting rod assembly.

[0021] It should be noted that the accompanying drawings are not necessarily drawn to scale, but are shown only in a schematic manner without affecting the reader's understanding. Detailed Implementation

[0022] Exemplary embodiments of this application will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the content of this application.

[0023] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0024] The distance between the indicator rod (locking rod) and the switch rail of a switch machine is not fixed, therefore the required length of the indicator connecting rod used to connect the indicator rod (locking rod) and the switch rail varies. Since the indicator connecting rod is usually a single molded part, its versatility is limited.

[0025] To address the aforementioned issues, embodiments of this application provide a connecting rod assembly suitable for steel turnout sleepers.

[0026] See Figure 1 , Figure 1 This is a schematic diagram illustrating the structure of the connecting rod assembly 100 connected to the switch rail 200 according to an embodiment of this application. The connecting rod assembly 100 is used to connect the switch machine and the switch rail 200, and may include a switch machine connector 10, a switch rail connector 20, and an insulating connector 30. The switch machine connector 10 is detachably connected to the rod joint of the switch machine, the switch rail connector 20 is detachably connected to the switch rail 200, and the insulating connector 30 is used to detachably and insulately connect the switch machine connector 10 and the switch rail connector 20.

[0027] The indicator connecting rod assembly 100 provided in the embodiments of this application detachably connects the switch machine connector 10 and the switch rail connector 20 via an insulating connector 30. This allows the indicator connecting rod assembly 100 to have a suitable length by selecting an insulating connector 30 of appropriate length, while maintaining the same size and shape of the switch machine connector 10 and the switch rail connector 200. This allows it to connect the switch machine indicator rod (locking rod) to the switch rail 200 to fit the distance between them. Indicator connecting rod assemblies 100 of different lengths can have switch machine connectors 10 and switch rail connectors 20 of the same size and shape, thereby improving the versatility of the indicator connecting rod assembly 100.

[0028] Furthermore, since the length of the connecting rod assembly 100 is typically quite long (approximately 2m), the switch machine connecting member 10 and the switch rail connecting member 20 are detachably connected by the insulating connector 30, which allows the switch machine connecting member 10, the switch rail connecting member 20, and the insulating connector 30 to be processed separately, thus reducing the processing difficulty of the connecting rod assembly 100.

[0029] In related technologies, when the stock rail and switch rail are fixed with steel turnout sleepers, it indicates that the connecting rod may come into contact with the steel turnout sleeper when it moves. This contact will connect the two switch rails, which in turn will connect the two stock rails, creating a red light band and generating an erroneous signal that the track is occupied, thus affecting the normal use of the track.

[0030] Therefore, the indicator connecting rod assembly 100 provided in the embodiments of this application insulates the switch machine connector 10 and the switch rail connector 20 through the insulating connector 30. When the steel turnout sleeper is used to fix the main rail and the switch rail 200, it can prevent the two switch rails 200 from being connected due to the indicator connecting rod assembly 100 accidentally touching the steel turnout sleeper, thereby preventing the two main rails from being connected and avoiding affecting the normal use of the track.

[0031] In some embodiments, the indicated connecting rod assembly 100 may include a plurality of insulating connectors 30 of different lengths, thereby facilitating the selection of insulating connectors 30 of appropriate lengths to ensure that the indicated connecting rod assembly 100 has a suitable length.

[0032] In some embodiments, the lever joint of the switch machine is connected to the indicator lever (locking lever) of the switch machine.

[0033] See Figures 2 to 4 , Figure 2 yes Figure 1 The diagram shows the assembled structure of the switch machine connectors, insulating connectors, and the switch rail connecting rod mentioned later. Figure 3 yes Figure 2 The diagram shown is a breakdown of the structure. Figure 4 yes Figure 2 The diagram shows a cross-sectional view of the structure. In some embodiments, the insulating connector 30 may include a metal connector 31 and two injection molded parts 32. Threaded connection grooves 310 are formed on both sides of the metal connector 31, and each injection molded part 32 is threadedly connected to the switch machine connector 10 or the switch rail connector 20 at the connection groove 310. When the switch rail 200 moves, it will cause the entire indicator connecting rod assembly 100 and the indicator rod (locking rod) of the switch machine to move. Therefore, the strength of the insulating connector 30 that connects the switch rail connector 20 and the switch machine connector 10 is required to be high. In this embodiment, the metal connector 31 is provided to ensure the overall mechanical strength of the insulating connector 30 after it is connected to the switch machine connector 10 or the switch rail connector 20. By providing the injection molded part 32 to thread the metal connector 31 to the switch machine connector 10 or the switch rail connector 20, insulation can be achieved, and the connection stability between the insulating connector 30 and the switch machine connector 10 or the switch rail connector 20 can be improved, thereby facilitating a stable connection between the insulating connector 30 and the switch machine connector or the switch rail connector 20.

[0034] See Figures 2 to 4In some embodiments, the metal connector 31 may include two end connecting sections 311 and a middle connecting section 312 for connecting the two end connecting sections 311. The two end connecting sections 311 each form a connecting groove 310, and the axes of the two end connecting sections 311 are parallel. The middle connecting section 312 may be a solid structure, integrally formed with the two end connecting sections 311. In the embodiments of this application, by setting the middle connecting section 312 as a solid structure and making it integrally formed with the two end connecting sections 311, the strength of the metal connector 31 can be further improved.

[0035] In some embodiments, the middle connecting section 312 is configured to form a bent section to provide clearance to the existing turnout structure and avoid interference between the middle connecting section 312 and the existing turnout structure. Since the outer diameter of the metal connector 31 is larger, forming the bent section on the metal connector 31, rather than on the switch machine connector 10 or the switch rail connector 20, is more conducive to ensuring the overall mechanical strength of the connecting rod assembly 100.

[0036] See Figure 2 and Figure 3 In some embodiments, the end connecting section 311 may form an injection hole 3110, through which the injection molded part 32 is injection molded between the connecting groove 310 and the switch machine connector 10 or the switch rail connector 20. In the embodiments of this application, the above-described configuration enhances the connection strength between the metal connector 31 and the switch machine connector 10, and between the metal connector 31 and the switch rail connector 20, making the connection between the metal connector 31 and the switch machine connector 10 or the switch rail connector more stable, which is beneficial for the switch rail 200 to drive the overall movement of the indicator connecting rod assembly 100.

[0037] For insulating connectors 30 of different lengths, the length of their end connection sections 311 can be different.

[0038] See Figures 2 to 4 ,as well as Figure 10 , Figure 10 yes Figure 1The diagram shows an assembly of the switch machine connector 10 and the switch machine rod joint 300. In some embodiments, the switch machine connector 10 may include a switch machine connecting rod 11 and a switch machine connector head 12 connected to the switch machine connecting rod 11. The switch machine connector head 12 may form a switch machine connecting hole 120 for a connecting pin 302 to pass through. The switch machine connector head 12 is configured to be inserted into the two connecting pieces 301 of the rod joint 300, so that the switch machine connector head 12 is connected to the rod joint 300 by the connecting pin 302 passing through the switch machine connecting hole 120 and the connecting holes 3010 of the two connecting pieces 301. When the switch machine's actuating rod moves the switch rail 200, the switch rail 200 moves the indicator connecting rod assembly 100, which in turn moves the switch machine's rod joint 300 and the switch machine's indicator rod (locking rod). In this embodiment, the above arrangement facilitates the transmission of force from the indicator connecting rod assembly 100 to the switch machine's rod joint 300, which in turn facilitates the indicator connecting rod assembly 100 moving the switch machine's rod joint 300.

[0039] See Figures 2 to 4 In some embodiments, the switch machine connecting rod 11 can be threaded to match the connecting groove 310 of the insulating connector 30, so that the switch machine connecting rod 11 and the insulating connector 30 can be threadedly connected, thereby making the connection between the switch machine connecting rod 11 and the insulating connector 30 more stable through the injection molded part 32.

[0040] See Figures 2 to 4 In some embodiments, the switch machine connecting rod 11 can be a straight rod. In such embodiments, by setting the switch machine connecting rod 11 as a straight rod without a bent section, it is beneficial to ensure the overall mechanical strength of the connecting rod assembly 100.

[0041] See Figure 1 and Figure 3 In some embodiments, the switch rail connector 20 may include a switch rail connecting rod 21. One end of the switch rail connecting rod 21 forms a threaded section 2101 for threaded connection with the connecting groove 310 of the insulating connector 30, thereby enabling a more stable connection between the switch rail connecting rod 21 and the insulating connector 30 through the injection-molded part 32. The other end of the switch rail connecting rod 21 forms a switch rail connecting section 2102 for connection with the switch rail 200, thereby connecting with the switch rail 200.

[0042] See Figure 1 and Figure 3 In some embodiments, the switch rail connecting rod 21 can be a straight rod. In such embodiments, by setting the switch rail connecting rod 21 as a straight rod without providing a bent section, it is beneficial to ensure the overall mechanical strength of the connecting rod assembly 100.

[0043] See Figure 1 , Figures 5 to 7 , Figure 5 This is a schematic diagram of the structure of the switch rail connector 20 and switch rail 200 after assembly according to an embodiment of this application. The switch rail connecting rod is omitted in the figure. Figure 6 yes Figure 5 The diagram shown is a breakdown of the structure. Figure 7 yes Figure 5 The diagram shows the structure after the second connector 23 and the rotating member 24 are assembled. In some embodiments, the switch rail connector 20 may further include a first connector 22, a second connector 23, a rotating member 24, and an axial adjustment member 25. The first connector 22 is used to connect with the switch rail 200; the second connector 23 is insulated from the first connector 22; the rotating member 24 is rotatably disposed on the second connector 23 in a vertical plane, and the rotating member 24 forms a channel 240 for the switch rail connecting section 2102 to pass through, and the switch rail connecting section 2102 can be rotated in the vertical plane by the rotating member 24 to pitch and swing in the vertical plane; the axial adjustment member 25 is used to connect the switch rail connecting section 2102 and the rotating member 24, and to adjust the connection position between the switch rail connecting section 2102 and the rotating member 24.

[0044] In this embodiment, by setting the first connector 22 and the second connector 23 to be insulated, it is possible to prevent the first connector 22 and the second connector 23 from accidentally connecting the two switch rails 200, thereby avoiding affecting the normal use of the track. By setting the rotating member 24, the switch rail connecting section 2102 can rotate in the vertical plane and thus pitch and swing in the vertical plane, preventing the switch rail connecting section 2102 from following the vertical movement of the second connector 23, thereby avoiding the adverse effects caused by the vertical movement of the switch rail connecting section 2102. By setting the axial adjustment member 25 to adjust the connection position between the switch rail connecting section 2102 and the rotating member 24, the axial length of the switch rail connecting rod 21 located between the insulated connector 30 and the second connector 23 can be finely adjusted, so that the turnout gap meets the standard requirements and the force transmission effect of the connecting rod assembly 100 is improved.

[0045] See Figure 3 In some embodiments, the switch rail connection section 2102 is threaded. See also Figure 5 , Figure 6 , Figure 8 as well as Figure 9 , Figure 8 yes Figure 5 The diagram shown illustrates the assembled structure of the locking and limiting component 251, the locking and limiting fitting component 252, and the rotating component 24. Figure 9 yes Figure 5The diagram shows the engagement of the locking stop 251 and the locking stop fitting 252. The axial adjusting member 25 may include the locking stop 251, at least one nut 253, and the locking stop fitting 252. The locking stop 251 is sleeved on the switch rail connecting section 2102 on one side of the rotating member 24. Each nut 253 is threadedly connected to the switch rail connecting section 2102 on the side of the locking stop 251 away from the rotating member 24 to prevent the locking stop 251 from moving along the switch rail connecting section 2102. The locking stop fitting 252 is threadedly connected to the switch rail connecting section 2102 on the other side of the rotating member 24, and the locking stop fitting 252 and the locking stop 251 engage in a locking engagement within the channel 240 of the rotating member 24 to limit the rotation of the rotating member 24.

[0046] In the embodiments of this application, the movement of the locking limit member 251 is restricted by the threaded engagement of the nut 253 with the switch rail connecting section 2102, thereby restricting the movement of the switch rail connecting section 2102 relative to the rotating member 24; at the same time, by setting the locking limit fitting member 252, the locking limit fitting member 252 and the locking limit member 251 are locked together within the rotating member 24, and the connection position between the switch rail connecting section 2102 and the rotating member 24 can be adjusted by simultaneously rotating the locking limit fitting member 252 and the locking limit member 251. When the nut 253 tightens the locking and limiting member 251, making it difficult for the locking and limiting member 251 to rotate, the locking and limiting fitting member 252 and the locking and limiting member 251 engage to prevent the locking and limiting fitting member 252 from rotating. This prevents the locking and limiting fitting member 252 from rotating relative to the switch rail connecting section 2102, and thus prevents the locking and limiting fitting member 252 from moving relative to the rotating member 24, ensuring that the axial length of the switch rail connecting rod 21 between the insulating connecting member 30 and the second connecting member 23 remains unchanged. Since the rotating member 24, when rotating in the vertical plane, causes the locking and limiting member 251 and the locking and limiting fitting member 252 to pitch and oscillate, which in turn causes the switch rail connecting section 2102 to pitch and oscillate, this helps to avoid adverse effects on the switch rail connecting section 2102.

[0047] In some embodiments, the snap-fit ​​limiting member 251 includes a first limiting body 2511 and a snap-fit ​​member 2512 connected to the first limiting body 2511, and the snap-fit ​​limiting mating member 252 includes a second limiting body 2521 and a snap-fit ​​mating member 2522 connected to the second limiting body 2521. The first limiting body 2511 and the second limiting body 2521 abut against the rotating member 24 on both sides of the rotating member 24, and the snap-fit ​​member 2512 and the snap-fit ​​mating member 2522 enter the channel 240 of the rotating member 24 and engage in a snap-fit ​​mating within the channel 240. The snap-fit ​​piece 2512 and the snap-fit ​​mating piece 2522 enter the channel 240 of the rotating piece 24 and engage within the channel 240, allowing the snap-fit ​​limiting piece 251 and the snap-fit ​​limiting mating piece 252 to rotate synchronously. The first limiting body 2511 and the second limiting body 2521 abut against the rotating piece 24 on both sides, thereby defining the connection position between the rotating piece 24 and the switch rail connecting section 2102.

[0048] In some embodiments, the snap-fit ​​member 2512 and the snap-fit ​​mating member 2522 respectively form a protrusion 2510 and a groove 2520 adapted to the shape of the protrusion 2510. The protrusion 2510 and the groove 2520 cooperate with each other to achieve snap-fit ​​engagement between the snap-fit ​​limiting member 251 and the snap-fit ​​limiting mating member 252, thereby enabling synchronous rotation of the snap-fit ​​limiting member 251 and the snap-fit ​​limiting mating member 252. The snap-fit ​​limiting member 251 has no internal threads and can rotate relative to the switch rail connecting section 2102.

[0049] See Figure 5 and Figure 6 In some embodiments, the first connector 22 extends in a horizontal direction and the second connector 23 extends in a vertical direction; the side of the second connector 23 away from the first connector 22 forms a through groove 230 that extends axially along the switch rail connecting section 2102; the rotating member 24 is rotatably disposed in the through groove 230 in a vertical plane. Since the height of the switch rail 200 is usually higher than the height of the switch rail connecting section 2102, the embodiments of this application, through the above-described arrangement, enable the switch rail 200 to drive the first connecting member 22 to translate when it moves, the first connecting member 22 to drive the second connecting member 23 to translate, and the second connecting member 23 to drive the switch rail connecting section 2102 to translate, thus achieving a better mechanical transmission effect. At the same time, by rotatably setting the rotating member 24 in the through groove 230 formed by the second connecting member 23 in the vertical plane, the rotating member 24 can rotate in the vertical plane. Therefore, when the second connecting member 23 moves vertically, the rotation of the rotating member 24 can drive the switch rail connecting section 2102 to pitch and swing in the vertical plane, thereby avoiding adverse effects on the switch rail connecting section 2102.

[0050] In some embodiments, see Figure 7 and Figure 8The rotating component 24 may include two rotating elements 241, which are rotatably disposed opposite each other in the through groove 230. Each rotating element 241 is configured to form a groove, and the grooves of the two rotating elements 241 together constitute a channel 240 for the tip rail connecting section 2102 to pass through.

[0051] In some embodiments, each rotating element 241 includes a rotating body 2411 and a rotating shaft 2412 connected to the rotating body 2411. The rotating body 2411 is configured to form a groove and is disposed within a through groove 230. The second connecting body 231 is configured to form a rotating hole 2310 communicating with the through groove 230. The rotating shaft 2412 is rotatably disposed within the rotating hole 2310. When the second connecting member 23 moves in the vertical direction, the rotating body 2411 rotates accordingly within the through groove 230.

[0052] In some embodiments, the first connector 22 may include a first connector body 221 and a first connector portion 222. The first connector body 221 extends along the extension direction of the switch rail 200, and the first connector portion 222 extends along the extension direction perpendicular to the extension direction of the switch rail 200. The first connector body 221 is connected to the switch rail 200 by bolts, and the first connector portion 222 is used to connect with the second connector 23. The first connector body 221 and the first connector portion 222 are integrally formed to improve the connection strength.

[0053] In some embodiments, the first connecting portion 222 is configured to form a first connecting hole 2220, and the second connecting portion 232 is configured to be inserted into the first connecting hole 2220 so as to connect the first connecting member 22 and the second connecting member 23 by means of a locking nut 262 threadedly connected to the second connecting portion 232.

[0054] In some embodiments, the second connector 23 may include a second connector body 231 and a second connector portion 232, the second connector body 231 and the second connector portion 232 being fixedly connected, the second connector body 231 being configured to form a through groove 230, and the second connector portion 232 being used to connect with the first connector portion 222.

[0055] In some embodiments, the second connecting body 231 is hollowed out to reduce the weight of the second connecting body 231.

[0056] In some embodiments, the switch rail connector 20 may further include a switch rail insulator 26 and an anti-movement member 27, wherein the switch rail insulator 26 is used to insulate between the first connection portion 222 and the second connection portion 232, and the anti-movement member 27 is used to prevent the switch rail insulator 26 from moving axially relative to the second connection portion 232.

[0057] In some embodiments, the switch rail insulator 26 may include two insulating pads 261. The two insulating pads 261 are disposed opposite to each other and configured to enter the first connection hole 2220, and the second connection portion 232 is configured to pass through the two insulating pads 261 so as to provide insulation between the two insulating pads 261 and the first connection portion 222 and the second connection portion 232.

[0058] In some embodiments, the switch rail insulation 26 may further include a gasket 263 disposed between the lock nut 262 and the insulation pad 261.

[0059] In some embodiments, the anti-moving member 27 may be a pin. The portion of the second connecting portion 232 above the locking nut 262 is configured to form a fixing hole 2320 for the anti-moving member 27 to pass through, so as to prevent the locking nut 262 from moving axially relative to the second connecting portion 232 and to prevent the locking nut 262 from disengaging.

[0060] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0061] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
