Description

Technical Field

[0001] This application relates to the technical field of railway switch conversion equipment, and particularly to a split action plate break indication structure for a switch machine. Background Art

[0002] The railway switch machine is a crucial component in the railway transportation system, responsible for switching the railway switch during train operation to ensure that the train runs safely and accurately on the predetermined track. With the continuous increase in railway transportation demand and technological progress, the design and performance of the switch machine are constantly optimized and improved to enhance its reliability and safety. Currently, the switch machine not only needs to have efficient switching capabilities but also a safety guarantee mechanism in case of abnormalities, especially the safety break indication function during switch jamming.

[0003] In the prior art, in order to achieve the safety break indication function during switch jamming, various mechanical devices are usually adopted. One common method is to drive a locking block to move through an action rod, thereby causing the locking iron to displace and trigger a series of chain reactions, such as the roller rising, the extrusion column compressing the disc spring group, the horizontal push rod pushing the vertical push rod, etc., and finally separating the moving contact group from the static contact group to cut off the connected contacts. Another method is to set up a multi-stage linkage mechanism between the action plate group and the detection rod to achieve the function of break indication during switch jamming through complex mechanical transmission. In addition, there is also a method of setting elastic elements at key positions and using their deformation to transmit the switch jamming force to achieve the purpose of break indication.

[0004] However, the above methods have some obvious defects in practical applications. First, these methods have relatively complex structures, involving a large number of components, resulting in high precision requirements for manufacturing and assembly, and increasing the production and maintenance costs. Second, due to the long transmission path, it is easy to affect the normal operation of the entire system due to a failure in a certain link. Especially during switch jamming, the phenomenon of incomplete switch jamming may occur, and the indication contacts cannot be effectively cut off, thus affecting train operation safety. Therefore, how to simplify the structure and improve the reliability has become an urgent technical problem to be solved. Summary of the Invention

[0005] To overcome the above technical problems, this application provides a split action plate break indication structure for a switch machine.

[0006] A split action plate break indication structure for a switch machine provided by this application adopts the following technical solutions:

[0007] A split action plate break indication structure for a switch machine, which is used to receive and transmit the derailment signal of the switch rail. The switch rail includes a first switch rail and a second switch rail, and comprises an indicating rod group, a first action plate group, a second action plate group, a first base and a contact group; the indicating rod group includes a first indicating rod and a second indicating rod, the first indicating rod is connected to the first switch rail, and the second indicating rod is connected to the second switch rail; the first indicating rod and the second indicating rod are both horizontally arranged, and their length directions are parallel to each other, and the first indicating rod is arranged directly above the second indicating rod; two first fitting grooves are formed in the first indicating rod along its length direction, two second fitting grooves are formed in the second indicating rod along its length direction, and each first fitting groove is located above one of the second fitting grooves; the side walls of the two first fitting grooves on the side close to each other are both inclined, and the side walls of the two second fitting grooves on the side close to each other are also both inclined; the first action plate group includes a first action rod, a first action frame, a first convex platform, a first reset part and a first fitting part; the first action rod is horizontally arranged, and the length direction of the first action rod is perpendicular to the length direction of the first indicating rod; the first action frame is vertically arranged, the first action frame is fixedly connected to one end of the first action rod, the first action frame is slidably connected to the first base, and the sliding direction of the first action frame is the same as the length direction of the first action rod; the first convex platform is fixedly arranged on the inner wall of the first action frame, and there are two along the vertical direction. The first convex platform located above can be matched with any one of the first fitting grooves, and the first convex platform located below can be matched with any one of the second fitting grooves; the second action plate group includes a second action rod, a second action frame, a second convex platform, a second reset part and a second fitting part; the second action rod is horizontally arranged, and the length direction of the second action rod is perpendicular to the length direction of the second indicating rod; the second action frame is vertically arranged, the second action frame is fixedly connected to one end of the second action rod, the second action frame is slidably connected to the first base, and the sliding direction of the second action frame is the same as the length direction of the second action rod; the second convex platform is fixedly arranged on the inner wall of the second action frame, and there are two along the vertical direction. The second convex platform located above can be matched with any one of the first fitting grooves, and the second convex platform located below can be matched with any one of the second fitting grooves; the first reset part is used to reset the first action plate group, and the second reset part is used to reset the second action plate group; the contact group is arranged above the indicating rod group, the first fitting part is arranged on the first action frame, and is used to transmit the state signal of the first action plate group to the contact group; the second fitting part is arranged on the second action frame, and is used to transmit the state signal of the second action plate group to the contact group.

[0008] By adopting the above technical solutions, a split action plate break indication structure for a switch machine with a simple structure and high reliability is realized. In this structure, a first mating groove and a second mating groove with inclined surfaces are arranged in the indicating rod group, as well as a first boss and a second boss that cooperate with them. When a turnout squeeze occurs, the indicating rod can move quickly when the switch rail is subjected to an external thrust, thereby driving the first action plate group or the second action plate group to move quickly, and then triggering the contact group to disconnect the indication circuit through the first mating part or the second mating part. This design not only simplifies the traditional multi-component transmission structure, improves the response speed and reliability, but also reduces the requirements for the accuracy of components and reduces the phenomenon of incomplete turnout squeeze. At the same time, through the design of the first reset part and the second reset part, it is ensured that the first action plate group and the second action plate group can automatically reset when they lose the passive driving force, which is convenient for subsequent operation and maintenance. In addition, for the turnout squeeze that occurs when the two switch rails are in different states, there are corresponding countermeasures. Specifically, when the switch rail is in the first normal state, the first switch rail is in the closed state and the second switch rail is in the separated state, the upper first boss is located in one of the first mating grooves, and the lower first boss is located in one of the second mating grooves; when a turnout squeeze occurs, both the first switch rail and the second switch rail move, driving both the first indicating rod and the second indicating rod to move along their respective length directions, so that the upper first boss moves out of the first mating groove under the action of the inclined surface of the first mating groove, and the lower first boss moves out of the second mating groove under the action of the inclined surface of the second mating groove. The movement of the two first bosses drives the first action frame to move, the first action frame drives the first action rod to move, and at the same time the first mating part moves together with the first action frame, transmitting the turnout squeeze signal to the contact group; when the switch rail is in the second normal state, the first switch rail is in the separated position and the second switch rail is in the closed state, the upper second boss is located in the other first mating groove, and the lower second boss is located in the other second mating groove; when a turnout squeeze occurs, both the first switch rail and the second switch rail move, driving both the first indicating rod and the second indicating rod to move along their respective length directions. The moving directions of the first indicating rod and the second indicating rod are opposite to the moving directions when the turnout squeeze occurs when the switch rail is in the first normal state, so that the upper second boss moves out of the first mating groove under the action of the inclined surface of the first mating groove, and the lower second boss moves out of the second mating groove under the action of the inclined surface of the second mating groove. The movement of the two second bosses drives the second action frame to move, the second action frame drives the second action rod to move, and at the same time the second mating part moves together with the second action frame, transmitting the turnout squeeze signal to the contact group.

[0009] Optionally, a first sliding groove is formed on the first base, and both the first action frame and the second action frame are slidably arranged in the first sliding groove, and the sliding directions are parallel to each other; a positioning plate is arranged between the first action frame and the second action frame, and one side of the positioning plate is fixedly connected to the first base.

[0010] By adopting the above technical solution, the first sliding groove formed on the first base enables the first action frame and the second action frame to slide stably within the first sliding groove, ensuring the smoothness and reliability of the action process. The positioning plate between the first action frame and the second action frame not only plays a limiting role to prevent dislocation during the sliding process of the two, but also enhances the stability of the entire structure. This design simplifies the structure, improves the response speed and accuracy of the action plate group, and effectively avoids the problem of incomplete switch squeezing in the prior art.

[0011] Optionally, it further includes a second base, on which a second sliding groove is formed; the first action plate group further includes a first auxiliary action frame; the second action plate group further includes a second auxiliary action frame; the first auxiliary action frame is fixedly connected to the side of the first action rod away from the first action frame; the second auxiliary action frame is fixedly connected to the side of the second action rod away from the second action frame; both the first auxiliary action frame and the second auxiliary action frame are slidably arranged within the second sliding groove, and the side of the positioning plate away from the first base is fixedly connected to the second base; the positioning plate is always located between the first action frame and the second action frame, between the first action rod and the second action rod, and between the first auxiliary action frame and the second auxiliary action frame.

[0012] By adopting the above technical solution, the added second base and the second sliding groove thereon enable the first auxiliary action frame and the second auxiliary action frame to slide stably within the second sliding groove, further improving the movement stability of the action plate group. At the same time, the position design of the positioning plate ensures the relative position between the first action frame and the second action frame remains unchanged, avoiding possible deviation and dislocation during the action process, and enhancing the reliability and accuracy of the entire structure. In addition, the introduction of the first auxiliary action frame and the second auxiliary action frame also increases the rigidity of the system.

[0013] Optionally, the first reset portion includes a first bottom plate and a first reset spring; the second reset portion includes a second bottom plate and a second reset spring; the first bottom plate is slidably arranged within the second sliding groove, and the first bottom plate is fixedly connected to the first auxiliary action frame; the second bottom plate is slidably arranged within the second sliding groove, and the second bottom plate is fixedly connected to the second auxiliary action frame; the first reset spring is arranged within the second sliding groove, with one end fixedly connected to the side wall of the second sliding groove and the other end fixedly connected to the first bottom plate, and the length direction of the first reset spring is the same as the sliding direction of the first auxiliary action frame; the second reset spring is arranged within the second sliding groove, with one end fixedly connected to the side wall of the second sliding groove and the other end fixedly connected to the second bottom plate, and the length direction of the second reset spring is the same as the sliding direction of the second auxiliary action frame.

[0014] By adopting the above technical solution, the first reset part realizes the automatic reset function of the first action plate group through the first bottom plate and the first reset spring, and the second reset part realizes the automatic reset function of the second action plate group through the second bottom plate and the second reset spring. When the first action plate group is displaced under the action of the indicating rod group, the first reset spring is compressed to store elastic potential energy. When the second action plate group is displaced under the action of the indicating rod group, the second reset spring is compressed to store elastic potential energy. Once the action of the indicating rod group disappears, the first reset spring and the second reset spring release energy, pushing the first bottom plate and the second bottom plate to drive the first auxiliary action frame and the second auxiliary action frame back to the initial position respectively, so that the first action plate group and the second action plate group are quickly reset, ensuring the normal working state of the switch machine. This design simplifies the reset mechanism and improves the reliability and response speed of the system.

[0015] Optionally, a first top seat is fixedly arranged above the first base, a first top groove is formed on one side of the first top seat close to the second base, and the tops of the first action frame and the second action frame are slidably arranged in the first top groove; the first reset part further includes a first reset auxiliary spring, and the second reset part further includes a second reset auxiliary spring; the first reset auxiliary spring is arranged in the first top groove, one end of the first reset auxiliary spring is fixedly connected to the side wall of the first top groove, and the other end is fixedly connected to the first action frame. The length direction of the first reset auxiliary spring is the same as the sliding direction of the first action frame; the second reset auxiliary spring is arranged in the second top groove, one end of the second reset auxiliary spring is fixedly connected to the side wall of the second top groove, and the other end is fixedly connected to the second action frame. The length direction of the second reset auxiliary spring is the same as the sliding direction of the second action frame.

[0016] By adopting the above technical solution, the design of the first top seat and the first top groove is added, so that the tops of the first action frame and the second action frame can slide in the first top groove, further improving the movement stability of the action plate group. At the same time, the first reset auxiliary spring and the second reset auxiliary spring are introduced and arranged in the first top groove and the second top groove respectively, enhancing the reset ability, ensuring that after a turnout squeeze occurs, the first action plate group and the second action plate group can be quickly reset, and improving the reliability and response speed of the system.

[0017] Optionally, both sides of the first boss are inclined, and both sides of the second boss are also inclined.

[0018] By adopting the above technical solution, the two sides of the first boss and the second boss are designed to be inclined, so that during the derailment process, it is easier for the first boss to form surface contact with the first mating groove and the second mating groove, and it is also easier for the second boss to form surface contact with the first mating groove and the second mating groove, thereby reducing the phenomenon of incomplete derailment. This design not only simplifies the structure of the derailment indication cut-off, but also improves the reliability and accuracy of the derailment response.

[0019] Optionally, the first mating part is located above the first action frame. The first mating part includes a first positioning rod and a first mating block. The first positioning rod is vertically arranged and fixedly arranged above the first action frame; the first mating block is also vertically arranged and fixedly arranged above the first positioning rod; a first ejector rod is provided on the contact group. The first ejector rod is horizontally arranged and located on one side of the first mating block; the first ejector rod and the first mating block are arranged in cooperation with each other. When the first mating block moves together with the first action frame, it can drive the first ejector rod to move.

[0020] By adopting the above technical solution, when derailment occurs when the switch rail is in the first normal state, the first action frame moves due to derailment, and the first mating block also moves accordingly, thereby driving the first ejector rod to move, realizing the displacement of the moving contact frame, so that the moving contact group in the contact group is separated from the static contact group, thus quickly cutting off the indication circuit, ensuring that the switch machine can timely cut off the indication during derailment, and improving the safety and reliability of the system.

[0021] Optionally, a first abutting groove is formed on one side of the first mating block close to the first ejector rod, and a first top wheel is provided on one side of the first ejector rod close to the first mating block; when the first action frame drives the first mating block to move away from the first auxiliary action frame, the first top wheel can abut against the side wall of the first abutting groove, driving the first top wheel and the first ejector rod to move away from the first mating block.

[0022] By adopting the above technical solution, when the first action frame is acted on by a derailment force, it can drive the first mating block to move. The first abutting groove on the first mating block cooperates with the first top wheel on the first ejector rod. When the first action frame drives the first mating block to move away from the first auxiliary action frame, the first top wheel can abut against the side wall of the first abutting groove, thereby driving the first top wheel and the first ejector rod to move away from the first mating block. This design enables the contacts to be quickly and reliably disconnected during derailment, ensuring the timely activation of the safe indication cut-off function.

[0023] Optionally, the second mating part is located above the second action frame. The second mating part includes a second positioning rod and a second mating block. The second positioning rod is vertically arranged and fixedly arranged above the second action frame. The second mating block is also vertically arranged and fixedly arranged above the second positioning rod. A second ejector rod is provided on the contact group. The second ejector rod is horizontally arranged and located on one side of the second mating block. The second ejector rod and the second mating block are arranged in cooperation with each other. When the second mating block moves together with the second action frame, the second ejector rod can be driven to move.

[0024] By adopting the above technical solution, when the switch rail is squeezed during the second normal state, the second action frame moves due to the squeezing, and the second mating block also moves accordingly, thereby driving the second ejector rod to move, realizing the displacement of the moving contact frame, separating the moving contact group and the static contact group in the contact group, and thus quickly cutting off the indication circuit, ensuring that the switch machine can timely disconnect the indication when squeezed, and improving the safety and reliability of the system.

[0025] Optionally, a second abutting groove is formed on one side of the second mating block close to the second ejector rod, and a second ejector wheel is provided on one side of the second ejector rod close to the second mating block. When the second action frame drives the second mating block to move in a direction away from the second sub-action frame, the second ejector wheel can abut against the side wall of the second abutting groove, driving the second ejector wheel and the second ejector rod to move in a direction away from the second mating block.

[0026] By adopting the above technical solution, the second action frame can drive the second mating block to move when subjected to the squeezing force, and the second abutting groove on the second mating block cooperates with the second ejector wheel on the second ejector rod. When the second action frame drives the second mating block to move in a direction away from the second sub-action frame, the second ejector wheel can abut against the side wall of the second abutting groove, and then drive the second ejector wheel and the second ejector rod to move in a direction away from the second mating block. This design enables the contacts to be quickly and reliably disconnected when squeezing occurs, ensuring the timely activation of the safety indication disconnection function.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up the indicating rod group, the first action plate group, the second action plate group, the first base, and the contact point group, a split action plate indication structure for a switch machine with a simple structure and high reliability is achieved. In this structure, by arranging a first mating groove and a second mating groove with inclined surfaces in the indicating rod group, as well as the first boss and the second boss that cooperate with them, when a turnout squeezing occurs, the indicating rod can move quickly when the switch rail is subjected to an external thrust, and then drive the first action plate group or the second action plate group to move quickly. Furthermore, the indicating circuit is triggered to disconnect through the first mating part or the second mating part. This design not only simplifies the traditional multi-component transmission structure, improves the response speed and reliability, but also reduces the requirement for the precision of components and reduces the phenomenon of incomplete turnout squeezing. At the same time, through the design of the first reset part and the second reset part, it is ensured that the first action plate group and the second action plate group can automatically reset when losing the passive driving force, which is convenient for subsequent operation and maintenance;

[0029] 2. The position design of the positioning plate ensures the relative position between the first action frame and the second action frame remains unchanged, avoiding possible offsets and misalignments during the action process, enhancing the reliability and accuracy of the entire structure. Through the design of the second base, it not only plays a limiting role to prevent the first action plate group and the second action plate group from being misaligned during the sliding process, but also enhances the stability of the entire structure. This design simplifies the structure, improves the response speed and accuracy of the action plate group, and effectively avoids the problem of incomplete turnout squeezing existing in the prior art;

[0030] 3. Through the design of the first return spring and the second return spring, when the first action plate group is displaced under the action of the indicating rod group, the first return spring is compressed and stores elastic potential energy. When the second action plate group is displaced under the action of the indicating rod group, the second return spring is compressed and stores elastic potential energy. Once the action of the indicating rod group disappears, the first return spring and the second return spring release energy, pushing the first bottom plate and the second bottom plate to drive the first auxiliary action frame and the second auxiliary action frame back to the initial position respectively, so that the first action plate group and the second action plate group can quickly reset, ensuring the normal working state of the switch machine. This design simplifies the reset mechanism and improves the reliability and response speed of the system;

[0031] 4. Through the design of the first mating block, the first top wheel, and the first top rod, when the first action frame is subjected to a turnout squeezing force, it can drive the first mating block to move. The first abutting groove on the first mating block cooperates with the first top wheel on the first top rod. When the first action frame drives the first mating block to move away from the first auxiliary action frame, the first top wheel can abut against the side wall of the first abutting groove, and then drive the first top wheel and the first top rod to move away from the first mating block. This design enables the contact points to be quickly and reliably disconnected when a turnout squeezing occurs, ensuring the timely activation of the safe indication disconnection function.

[0041] An embodiment of the present application discloses a split action plate break indication structure for a switch machine, which is used to receive and transmit the squeezing signal of the switch rail.

[0042] Refer to Figure 2 and Figure 3 , two first mating grooves 111 are formed along the length direction of the first indicating rod 11, two second mating grooves 121 are formed along the length direction of the second indicating rod 12, and each first mating groove 111 is located above a second mating groove 121; the side walls of the two first mating grooves 111 on the side close to each other are both inclined, and the side walls of the two second mating grooves 121 on the side close to each other are also both inclined; the contact group 6 is arranged above the indicating rod group 1; the positioning plate 7 is arranged between the first action plate group 2 and the second action plate group 3.

[0043] A split action plate break indication structure for a switch machine with a simple structure and high reliability is realized. Among them, the indicating rod group 1 is used to transmit the squeezing signal. When the switch rail is squeezed, the first indicating rod 11 can be driven to move by the first switch rail, and the second indicating rod 12 can be driven to move by the second switch rail. The first action plate group 2 and the second action plate group 3 are respectively used to transmit the squeezing signals when the switch rail is in different states. Specifically, when the switch rail is in the first normal state, the first switch rail is in the closed state and the second switch rail is in the separated state, at this time the first action plate group 2 is used to receive the squeezing signal transmitted by the indicating rod group 1; when the switch rail is in the second normal state, the first switch rail is in the separated position and the second switch rail is in the closed state, at this time the second action plate group 3 is used to receive the squeezing signal transmitted by the indicating rod group 1; the contact group 6 is used to receive the squeezing signals transmitted by the first action plate group 2 and the second action plate group 3, and separate the moving contact group in the contact group 6 from the static contact group, so as to quickly cut off the indication circuit and ensure that the switch machine can timely disconnect the indication when squeezed.

The upper first boss 23 can cooperate with any one of the first mating grooves 111, and the lower first boss 23 can cooperate with any one of the second mating grooves 121; the first reset portion 24 is used to reset the first actuating plate group 2; the first mating portion 25 is arranged on the first actuating frame 22 and is used to transmit the state signal of the first actuating plate group 2 to the contact group 6.

[0045] When the switch rail is in the first normal state, the first switch rail is in the closed state and the second switch rail is in the separated state, the upper first boss 23 is located in one of the first mating grooves 111, and the lower first boss 23 is located in one of the second mating grooves 121; when a derailment occurs, both the first switch rail and the second switch rail move, driving both the first indicating rod 11 and the second indicating rod 12 to move along their respective length directions, so that the upper first boss 23 moves out of the first mating groove 111 under the action of the inclined surface of the first mating groove 111, and the lower first boss 23 moves out of the second mating groove 121 under the action of the inclined surface of the second mating groove 121. The movement of the two first bosses 23 drives the first actuating frame 22 to move, the first actuating frame 22 drives the first actuating rod 21 to move, and at the same time, the first mating portion 25 moves together with the first actuating frame 22 to transmit the derailment signal to the contact group 6.

[0046] Refer to Figure 3 and Figure 5, the second moving plate group 3 includes a second moving rod 31, a second moving frame 32, a second boss 33, a second reset portion 34 and a second engaging portion 35; the second moving rod 31 is horizontally arranged, and the length direction of the second moving rod 31 is perpendicular to the length direction of the second indicating rod 12; the second moving frame 32 is vertically arranged, the second moving frame 32 is fixedly connected to one end of the second moving rod 31, the second moving frame 32 is slidably connected to the first base 4, and the sliding direction of the second moving frame 32 is the same as the length direction of the second moving rod 31; the second boss 33 is fixedly arranged on the inner wall of the second moving frame 32, and there are two along the vertical direction. The second boss 33 located above can cooperate with any one of the first engaging grooves 111, and the second boss 33 located below can cooperate with any one of the second engaging grooves 121; the second reset portion 34 is used to reset the second moving plate group 3; the second engaging portion 35 is arranged on the second moving frame 32 and is used to transmit the state signal of the second moving plate group 3 to the contact group 6.

[0047] When the switch rail is in the second normal state, the first switch rail is in the separated position and the second switch rail is in the closed state, the second boss 33 above is located in another first engaging groove 111, and the second boss 33 below is located in another second engaging groove 121; when a turnout jam occurs, both the first switch rail and the second switch rail move, driving both the first indicating rod 11 and the second indicating rod 12 to move along their respective length directions. The moving directions of the first indicating rod 11 and the second indicating rod 12 are opposite to the moving directions when a turnout jam occurs when the switch rail is in the first normal state, so that the second boss 33 above moves out of the first engaging groove 111 under the action of the inclined surface of the first engaging groove 111, and the second boss 33 below moves out of the second engaging groove 121 under the action of the inclined surface of the second engaging groove 121. The movement of the two second bosses 33 drives the second moving frame 32 to move, the second moving frame 32 drives the second moving rod 31 to move, and at the same time the second engaging portion 35 moves together with the second moving frame 32 to transmit the turnout jam signal to the contact group 6.

[0048] Refer to Figure 1 , a first sliding groove 41 is formed on the first base 4, and both the first moving frame 22 and the second moving frame 32 are slidably arranged in the first sliding groove 41, and their sliding directions are parallel to each other; a positioning plate 7 is arranged between the first moving frame 22 and the second moving frame 32, and one side of the positioning plate 7 is fixedly connected to the first base 4. The first sliding groove 41 formed on the first base 4 enables the first moving frame 22 and the second moving frame 32 to slide stably in the first sliding groove 41, ensuring the smoothness and reliability of the movement process. The positioning plate 7 between the first moving frame 22 and the second moving frame 32 not only plays a limiting role to prevent the two from being misaligned during the sliding process, but also enhances the stability of the entire structure.

[0049] Refer to Figure 1 andFigure 6 On the second base 5, a second sliding groove 51 is provided; the first action plate group 2 further includes a first auxiliary action frame 26; the second action plate group 3 further includes a second auxiliary action frame 36; the first auxiliary action frame 26 is fixedly connected to the side of the first action rod 21 away from the first action frame 22; the second auxiliary action frame 36 is fixedly connected to the side of the second action rod 31 away from the second action frame 32; both the first auxiliary action frame 26 and the second auxiliary action frame 36 are slidably arranged in the second sliding groove 51, and the side of the positioning plate 7 away from the first base 4 is fixedly connected to the second base 5; the positioning plate 7 is always located between the first action frame 22 and the second action frame 32, between the first action rod 21 and the second action rod 31, and between the first auxiliary action frame 26 and the second auxiliary action frame 36.

[0050] Refer to Figure 4 and Figure 5 As shown in FIGS. and, two third bosses 27 are fixedly arranged on the first auxiliary action frame 26 in the vertical direction, and two fourth bosses 37 are fixedly arranged on the second auxiliary action frame 36 in the vertical direction. The indicating rod group 1 can not only cooperate with the first boss 23 and the second boss 33, but also pass through the first auxiliary action frame 26 and the second auxiliary action frame 36 and cooperate with the third boss 27 and the fourth boss 37.

[0051] Refer to Figure 1 and Figure 6 As shown in FIGS. and, the first reset part 24 includes a first bottom plate 241 and a first reset spring 242; the second reset part 34 includes a second bottom plate 341 and a second reset spring 342; the first bottom plate 241 is slidably arranged in the second sliding groove 51 and is located on the side of the first auxiliary action frame 26 away from the positioning plate 7, and the first bottom plate 241 is fixedly connected to the first auxiliary action frame 26; the second bottom plate 341 is slidably arranged in the second sliding groove 51 and is located on the side of the second auxiliary action frame 36 away from the positioning plate 7, and the second bottom plate 341 is fixedly connected to the second auxiliary action frame 36; the first reset spring 242 is arranged in the second sliding groove 51, one end is fixedly connected to the side wall of the second sliding groove 51, and the other end is fixedly connected to the first bottom plate 241. The length direction of the first reset spring 242 is the same as the sliding direction of the first auxiliary action frame 26; the second reset spring 342 is arranged in the second sliding groove 51, one end is fixedly connected to the side wall of the second sliding groove 51, and the other end is fixedly connected to the second bottom plate 341. The length direction of the second reset spring 342 is the same as the sliding direction of the second auxiliary action frame 36.

[0052] The first reset part 24 realizes the automatic reset function of the first moving plate group 2 through the first bottom plate 241 and the first reset spring 242, and the second reset part 34 realizes the automatic reset function of the second moving plate group 3 through the second bottom plate 341 and the second reset spring 342. When the first moving plate group 2 is displaced under the action of the indicating rod group 1, the first reset spring 242 is compressed to store elastic potential energy. When the second moving plate group 3 is displaced under the action of the indicating rod group 1, the second reset spring 342 is compressed to store elastic potential energy. Once the action of the indicating rod group 1 disappears, the first reset spring 242 and the second reset spring 342 release energy, pushing the first bottom plate 241 and the second bottom plate 341 to drive the first auxiliary moving frame 26 and the second auxiliary moving frame 36 back to the initial position respectively, so that the first moving plate group 2 and the second moving plate group 3 are quickly reset, ensuring the normal working state of the switch machine.

[0053] Refer to Figure 1 and Figure 6 As shown in FIGS. and, a first top seat 8 is fixedly arranged above the first base 4. A first top groove 81 is formed on one side of the first top seat 8 close to the second base 5. The tops of the first moving frame 22 and the second moving frame 32 are slidably arranged in the first top groove 81. The first reset part 24 further includes a first auxiliary reset spring 243, and the second reset part 34 further includes a second auxiliary reset spring 343. The first auxiliary reset spring 243 is arranged in the first top groove 81. One end of the first auxiliary reset spring 243 is fixedly connected to the side wall of the first top groove 81, and the other end is fixedly connected to the first moving frame 22. The length direction of the first auxiliary reset spring 243 is the same as the sliding direction of the first moving frame 22. The second auxiliary reset spring 343 is arranged in the first top groove 81. One end of the second auxiliary reset spring 343 is fixedly connected to the side wall of the first top groove 81, and the other end is fixedly connected to the second moving frame 32. The length direction of the second auxiliary reset spring 343 is the same as the sliding direction of the second moving frame 32. The design of the first top seat 8 and the first top groove 81 is added, so that the tops of the first moving frame 22 and the second moving frame 32 can slide in the first top groove 81, further improving the movement stability of the moving plate group. At the same time, the first auxiliary reset spring 243 and the second auxiliary reset spring 343 are introduced and arranged in the first top groove 81 and the first top groove 81 respectively, enhancing the reset ability and ensuring that after a derailment occurs, the first moving plate group 2 and the second moving plate group 3 can be quickly reset, improving the reliability and response speed of the system.

[0054] Refer to Figure 4 and Figure 5, both sides of the first boss 23 are inclined, and both sides of the second boss 33 are also inclined. The inclined design of both sides of the first boss 23 and the second boss 33 enables the first boss 23 to more easily form surface contact with the first mating groove 111 and the second mating groove 121 during the switch squeezing process, and the second boss 33 can also more easily form surface contact with the first mating groove 111 and the second mating groove 121, thereby reducing the phenomenon of incomplete switch squeezing. This design not only simplifies the structure of the switch squeezing indication breaking, but also improves the reliability and accuracy of the switch squeezing response.

[0055] Refer to Figure 6 and Figure 7 , the first mating part 25 is located above the first action frame 22. The first mating part 25 includes a first positioning rod 251 and a first mating block 252. The first positioning rod 251 is vertically arranged and fixedly installed above the first action frame 22; the first mating block 252 is also vertically arranged and fixedly installed above the first positioning rod 251; a first ejector rod 61 is provided on the contact set 6. The first ejector rod 61 is horizontally arranged and located on one side of the first mating block 252; the first ejector rod 61 and the first mating block 252 are arranged in cooperation with each other. When the first mating block 252 moves together with the first action frame 22, it can drive the first ejector rod 61 to move.

[0056] Refer to Figure 6 and Figure 7 , a first abutting groove 2521 is formed on one side of the first mating block 252 close to the first ejector rod 61, and a first top wheel 62 is provided on one side of the first ejector rod 61 close to the first mating block 252; when the first action frame 22 drives the first mating block 252 to move away from the first sub-action frame 26, the first top wheel 62 can abut against the side wall of the first abutting groove 2521, driving the first top wheel 62 and the first ejector rod 61 to move away from the first mating block 252.

[0057] When a switch squeeze occurs when the switch rail is in the first normal state, the first action frame 22 moves due to the switch squeeze. The first action frame 22 drives the first mating block 252 to move. The first abutting groove 2521 on the first mating block 252 cooperates with the first top wheel 62 on the first ejector rod 61. The first action frame 22 drives the first mating block 252 to move away from the first sub-action frame 26. The first top wheel 62 can abut against the side wall of the first abutting groove 2521, thereby driving the first top wheel 62 and the first ejector rod 61 to move away from the first mating block 252, realizing the displacement of the moving contact frame, separating the moving contact set and the static contact set in the contact set 6, and thus quickly cutting off the indication circuit to ensure that the switch machine can timely break the indication during the switch squeeze.

[0058] Refer to Figure 6 and Figure 7, the second engaging portion 35 is located above the second moving frame 32. The second engaging portion 35 includes a second positioning rod 351 and a second engaging block 352. The second positioning rod 351 is vertically arranged and fixedly disposed above the second moving frame 32; the second engaging block 352 is also vertically arranged and fixedly disposed above the second positioning rod 351; a second ejector rod 63 is provided on the contact group 6. The second ejector rod 63 is horizontally arranged and located on one side of the second engaging block 352; the second ejector rod 63 and the second engaging block 352 are arranged in mutual cooperation. When the second engaging block 352 moves together with the second moving frame 32, it can drive the second ejector rod 63 to move.

[0059] Refer to Figure 6 and Figure 7 , a second abutting groove 3521 is formed on one side of the second engaging block 352 close to the second ejector rod 63, and a second ejector wheel 64 is provided on one side of the second ejector rod 63 close to the second engaging block 352; when the second moving frame 32 drives the second engaging block 352 to move in a direction away from the second auxiliary moving frame 36, the second ejector wheel 64 can abut against the side wall of the second abutting groove 3521, driving the second ejector wheel 64 and the second ejector rod 63 to move in a direction away from the second engaging block 352.

[0060] When a turnout squeeze occurs when the switch rail is in the second normal state, the second moving frame 32 moves due to the turnout squeeze. The second moving frame 32 drives the second engaging block 352 to move. The second abutting groove 3521 on the second engaging block 352 cooperates with the second ejector wheel 64 on the second ejector rod 63. The second moving frame 32 drives the second engaging block 352 to move in a direction away from the second auxiliary moving frame 36. The second ejector wheel 64 can abut against the side wall of the second abutting groove 3521, thereby driving the second ejector wheel 64 and the second ejector rod 63 to move in a direction away from the second engaging block 352, realizing the displacement of the moving contact frame, separating the moving contact group in the contact group 6 from the static contact group, and thus quickly cutting off the indication circuit to ensure that the switch machine can timely disconnect the indication when a turnout squeeze occurs.

[0061] The implementation principle of a split action plate indication cut-off structure for a switch machine in an embodiment of the present application is as follows:

[0062] This structure is designed by setting a first mating groove 111 with an inclined surface and a second mating groove 121 within the indicating rod group 1, along with the first boss 23 and the second boss 33 that mate with them. When a derailment occurs, the indicating rod can move quickly when the switch rail is subjected to an external thrust, thereby driving the first actuator plate group 2 or the second actuator plate group 3 to move rapidly. Subsequently, the first mating portion 25 or the second mating portion 35 is triggered to disconnect the contact group 6 from the indicating circuit. This design not only simplifies the traditional multi-component transmission structure, improves the response speed and reliability, but also reduces the requirements for the precision of components and minimizes the phenomenon of incomplete derailment. At the same time, through the design of the first reset portion 24 and the second reset portion 34, it is ensured that the first actuator plate group 2 and the second actuator plate group 3 can automatically reset when they lose the passive driving force, facilitating subsequent operation and maintenance. In addition, different coping methods are adopted for derailments occurring when the two switch rails are in different states.

[0063] When the switch rail is in the first normal state, with the first switch rail in the closed state and the second switch rail in the separated state, the upper first boss 23 is located within one of the first mating grooves 111, and the lower first boss 23 is located within one of the second mating grooves 121. During a derailment, both the first switch rail and the second switch rail move, driving the first indicating rod 11 and the second indicating rod 12 to move along their respective lengths. As a result, the upper first boss 23 moves out of the first mating groove 111 under the action of the inclined surface of the first mating groove 111, and the lower first boss 23 moves out of the second mating groove 121 under the action of the inclined surface of the second mating groove 121. The movement of the two first bosses 23 drives the first actuator frame 22 to move, and the first actuator frame 22 drives the first mating block 252 to move. The first abutting groove 2521 on the first mating block 252 cooperates with the first top wheel 62 on the first ejector rod 61. The first actuator frame 22 drives the first mating block 252 to move away from the first auxiliary actuator frame 26. The first top wheel 62 can abut against the side wall of the first abutting groove 2521, thereby driving the first top wheel 62 and the first ejector rod 61 to move away from the first mating block 252, achieving the displacement of the moving contact frame and separating the moving contact group from the static contact group within the contact group 6, thus quickly cutting off the indicating circuit and ensuring that the switch machine can promptly disconnect the indication during a derailment.

[0064] When the switch rail is in the second normal state, the first switch rail is in the separated position and the second switch rail is in the closed state, the upper second boss 33 is located in the other first fitting groove 111, and the lower second boss 33 is located in the other second fitting groove 121; when a derailment occurs, both the first switch rail and the second switch rail move, driving both the first indicating rod 11 and the second indicating rod 12 to move along their respective length directions. The moving directions of the first indicating rod 11 and the second indicating rod 12 are opposite to the moving directions when a derailment occurs when the switch rail is in the first normal state, causing the upper second boss 33 to move out of the first fitting groove 111 under the action of the inclined surface of the first fitting groove 111, and the lower second boss 33 to move out of the second fitting groove 121 under the action of the inclined surface of the second fitting groove 121. The movement of the two second bosses 33 drives the second action frame 32 to move, the second action frame 32 drives the second fitting block 352 to move, the second abutting groove 3521 on the second fitting block 352 cooperates with the second top wheel 64 on the second ejector rod 63, the second action frame 32 drives the second fitting block 352 to move away from the second auxiliary action frame 36, and the second top wheel 64 can abut against the side wall of the second abutting groove 3521, thereby driving the second top wheel 64 and the second ejector rod 63 to move away from the second fitting block 352, realizing the displacement of the moving contact frame, separating the moving contact group from the static contact group in the contact group 6, so as to quickly cut off the indication circuit and ensure that the switch machine can timely disconnect the indication when a derailment occurs.

[0065] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
