Description

Technical Field

[0001] The present application relates to the technical field of railway turnout switching equipment, and in particular to a split action plate break indication structure for a switch machine. Background Art

[0002] Railway turnout switch machines are a vital component of the railway transportation system. They are responsible for switching turnouts during train operation to ensure that trains run safely and accurately on the predetermined track. With the continuous increase in railway transportation demand and technological progress, the design and performance of turnout machines are also being continuously optimized and improved to enhance their reliability and safety. At present, turnout machines are not only required to have efficient switching capabilities, but also to have safety protection mechanisms in abnormal situations, especially the safety trip indication function when the turnout is squeezed.

[0003] In the prior art, in order to realize the function of safety disconnection indication during branch squeezing, a variety of mechanical devices are usually used. One common method is to use an action rod to drive the lock block to move, thereby causing the locking iron to be displaced, triggering a series of chain reactions, such as the roller rising, the squeezing column compressing the disc spring group, the horizontal push rod pushing the vertical push rod, etc., and finally the moving contact group is separated from the static contact group, cutting off the connected contacts. Another method is to set a multi-stage linkage mechanism between the action plate group and the detection rod, and realize the function of branch squeezing disconnection indication through complex mechanical transmission. In addition, there is a method of setting an elastic element at a key position, and using its deformation to transmit the squeezing force, so as to achieve the purpose of disconnection indication.

[0004] However, the above methods have some obvious defects in practical applications. First, these methods are relatively complex in structure and involve a large number of parts, which leads to high precision requirements for manufacturing and assembly, and increases the cost of production and maintenance. Secondly, due to the long transmission path, it is easy for a failure in a certain link to affect the normal operation of the entire system, especially when the branching occurs, the branching may not be in place, and the indicating contact point cannot be effectively cut off, thus affecting driving safety. Therefore, how to simplify the structure and improve reliability has become a technical problem that needs to be solved urgently. Summary of the invention

The structure is provided with a first matching groove and a second matching groove with an inclined surface, and a first boss and a second boss matched therewith, so that when a branching occurs, the indicating rod can move rapidly when the pointed rail is subjected to an external thrust, thereby driving the first action plate group or the second action plate group to move rapidly, and then triggering the contact group to disconnect the indication circuit through the first matching part or the second matching 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 branching not being in place. 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 the passive driving force is lost, which is convenient for subsequent operation and maintenance. In addition, there are corresponding response methods for the squeezing and divergence that occurs when the two point rails are in different states, specifically: when the point rails are in a first normal state, the first point rail is in a close contact state, and the second point rail is in a repulsive state, the upper first boss is located in one of the first matching grooves, and the lower first boss is located in one of the second matching grooves; when squeezing and divergence occur, both the first point rail and the second point rail move, driving the first indicating rod and the second indicating rod to move along their respective length directions, so that the upper first boss moves outside the first matching groove under the action of the inclined surface of the first matching groove, and the lower first boss moves outside the second matching groove under the action of the inclined surface of the second matching groove, the movement of the two first bosses drives the first action frame to move, and the first action frame drives the first action rod to move, and at the same time the first matching part moves together with the first action frame to transmit the squeezing and divergence signal to the contact group; when the point rails are in a first normal state, the first point rail is in a close contact state, and the second point rail is in a repulsive state, and the upper first boss is located in one of the first matching grooves, and the lower first boss is located in one of the second matching grooves; In the second normal state, the first point rail is located in the repulsive position, and when the second point rail is in the close contact state, the upper second boss is located in another first matching groove, and the lower second boss is located in another second matching groove; when squeezing and diverging occur, the first point rail and the second point rail both move, driving the first indicating rod and the second indicating rod to move along their respective length directions, and the movement directions of the first indicating rod and the second indicating rod are opposite to the movement directions of the point rails when squeezing and diverging occur in the first normal state, so that the upper second boss moves outside the first matching groove under the action of the inclined surface of the first matching groove, and the lower second boss moves outside the second matching groove under the action of the inclined surface of the second matching groove, and the movement of the two second bosses drives the second action frame to move, and the second action frame drives the second action rod to move, and at the same time, the second matching part moves together with the second action frame to transmit the squeezing and diverging signal to the contact group.

[0008] Optionally, a first sliding groove is provided on the first base, and the first action frame and the second action frame are both slidably set in the first sliding groove, and the sliding directions are parallel to each other; a positioning plate is provided between the first action frame and the second action frame, and one side of the positioning plate is fixedly connected to the first base.

[0009] By adopting the above technical solution, the first slide groove provided on the first base enables the first action frame and the second action frame to slide stably in the first slide 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 the two 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 insufficient squeezing in the prior art.

[0010] Optionally, it also includes a second base, on which a second slide groove is provided; the first action plate group also includes a first secondary action frame; the second action plate group also includes a second secondary action frame; the first secondary action frame is fixedly connected to a side of the first action rod away from the first action frame; the second secondary action frame is fixedly connected to a side of the second action rod away from the second action frame; the first secondary action frame and the second secondary action frame are both slidably arranged in the second slide 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 secondary action frame and the second secondary action frame.

[0011] By adopting the above technical solution, the second base and the second slide groove thereon are added, so that the first sub-action frame and the second sub-action frame can slide stably in the second slide groove, further improving the movement stability of the action plate group. At the same time, the position design of the positioning plate ensures that the relative position between the first action frame and the second action frame remains unchanged, avoiding possible offset and dislocation during the action process, and enhancing the reliability and accuracy of the entire structure. In addition, the introduction of the first sub-action frame and the second sub-action frame also increases the rigidity of the system.

When the first action plate group is displaced by the indicating rod group, the first reset spring is compressed to store elastic potential energy, and when the second action plate group is displaced by the indicating rod group, the second reset spring is compressed to store elastic potential energy. Once the effect of the indicating rod group disappears, the first reset spring and the second reset spring release energy, push the first bottom plate and the second bottom plate to drive the first auxiliary action frame and the second auxiliary action frame to return 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.

[0016] Optionally, two sides of the first boss are inclined, and two sides of the second boss are also inclined.

[0017] By adopting the above technical solution, the first boss and the second boss are designed with inclined sides, so that during the squeezing process, the first boss and the first matching groove and the second matching groove are more likely to form surface contact, and the second boss and the first matching groove and the second matching groove are also more likely to form surface contact, thereby reducing the phenomenon of squeezing out of position.

[0020] Optionally, a first abutment groove is provided on a side of the first mating block close to the first push rod, and a first push wheel is provided on a side of the first push rod close to the first mating block; when the first action frame drives the first mating block to move in a direction away from the first secondary action frame, the first push wheel can abut against the side wall of the first abutment groove, driving the first push wheel and the first push rod to move in a direction away from the first mating block.

When the first action frame drives the first matching block to move in a direction away from the first secondary action frame, the first top wheel can abut against the side wall of the first abutment groove, thereby driving the first top wheel and the first top rod to move in a direction away from the first matching block.

[0024] Optionally, a second abutment groove is provided on a side of the second mating block close to the second push rod, and a second push wheel is provided on a side of the second push 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 secondary action frame, the second push wheel can abut against the side wall of the second abutment groove, driving the second top wheel and the second push rod to move in a direction away from the second mating block.

The first slide groove 41 provided on the first base 4 enables the first action frame 22 and the second action frame 32 to slide stably in the first slide groove 41, ensuring the smoothness and reliability of the action process. The positioning plate 7 between the first action frame 22 and the second action 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.

The design of the first top seat 8 and the first top groove 81 is added, so that the tops of the first action frame 22 and the second action frame 32 can slide in the first top groove 81, further improving the movement stability of the action plate group. At the same time, the first reset auxiliary spring 243 and the second reset auxiliary spring 343 are introduced, which are respectively arranged in the first top groove 81 and the first top groove 81, to enhance the reset ability, ensure that after the squeezing occurs, the first action plate group 2 and the second action plate group 3 can be quickly reset, and improve the reliability and response speed of the system.

[0042] Reference Figure 4 and Figure 5, the two sides of the first boss 23 are inclined, and the two sides of the second boss 33 are also inclined. The first boss 23 and the second boss 33 are designed to be inclined on both sides, so that during the squeezing process, the first boss 23 and the first matching groove 111 and the second matching groove 121 are more likely to form surface contact, and the second boss 33 and the first matching groove 111 and the second matching groove 121 are also more likely to form surface contact, thereby reducing the phenomenon of squeezing out of position. This design not only simplifies the structure of the squeezing response, but also improves the reliability and accuracy of the squeezing response.

[0043] Reference Figure 6 and Figure 7 The first matching portion 25 is located above the first action frame 22. The first matching portion 25 includes a first positioning rod 251 and a first matching block 252.

When the first matching block 252 moves with the first action frame 22, it can drive the first push rod 61 to move.

[0044] Reference Figure 6 and Figure 7 A first abutting groove 2521 is provided on the side of the first matching block 252 close to the first push rod 61, and a first push wheel 62 is provided on the side of the first push rod 61 close to the first matching block 252; when the first action frame 22 drives the first matching block 252 to move in the direction away from the first secondary action frame 26, the first push wheel 62 can abut against the side wall of the first abutting groove 2521, driving the first top wheel 62 and the first push rod 61 to move in the direction away from the first matching block 252.

[0045] When the point rail is in the first normal state and a branching occurs, the first action frame 22 moves due to the branching, and the first action frame 22 drives the first matching block 252 to move. The first abutment groove 2521 on the first matching block 252 cooperates with the first top wheel 62 on the first push rod 61, and the first action frame 22 drives the first matching block 252 to move in the direction away from the first secondary action frame 26. The first top wheel 62 can abut against the side wall of the first abutment groove 2521, thereby driving the first top wheel 62 and the first push rod 61 to move in the direction away from the first matching block 252, realizing the displacement of the moving contact frame, so that the moving contact group and the static contact group in the contact group 6 are separated, thereby quickly cutting off the indication circuit, ensuring that the switch can disconnect the indication in time when the switch is squeezed.

[0046] Reference Figure 6 and Figure 7The second matching portion 35 is located above the second action frame 32. The second matching portion 35 includes a second positioning rod 351 and a second matching block 352. The second positioning rod 351 is vertically arranged and fixedly arranged above the second action frame 32; the second matching block 352 is also vertically arranged and fixedly arranged above the second positioning rod 351; a second push rod 63 is provided on the contact group 6, and the second push rod 63 is horizontally arranged and located on one side of the second matching block 352; the second push rod 63 and the second matching block 352 are arranged to cooperate with each other. When the second matching block 352 moves with the second action frame 32, it can drive the second push rod 63 to move.

[0047] Reference Figure 6 and Figure 7 A second abutment groove 3521 is provided on the side of the second matching block 352 close to the second push rod 63, and a second push wheel 64 is provided on the side of the second push rod 63 close to the second matching block 352; when the second action frame 32 drives the second matching block 352 to move in the direction away from the second secondary action frame 36, the second top wheel 64 can abut against the side wall of the second abutment groove 3521, driving the second top wheel 64 and the second push rod 63 to move in the direction away from the second matching block 352.

[0048] When the point rail is in the second normal state and a divergence occurs, the second action frame 32 moves due to the divergence, and the second action frame 32 drives the second matching block 352 to move. The second abutment groove 3521 on the second matching block 352 cooperates with the second top wheel 64 on the second push rod 63, and the second action frame 32 drives the second matching block 352 to move in the direction away from the second auxiliary action frame 36. The second top wheel 64 can abut against the side wall of the second abutment groove 3521, thereby driving the second top wheel 64 and the second push rod 63 to move in the direction away from the second matching block 352, realizing the displacement of the moving contact frame, so that the moving contact group and the static contact group in the contact group 6 are separated, thereby quickly cutting off the indication circuit, ensuring that the switch can disconnect the indication in time when a divergence occurs.

[0049] The implementation principle of the split action plate break indication structure for a switch machine in the embodiment of the present application is as follows: This structure is provided with a first matching groove 111 and a second matching groove 121 with a bevel in the indicating rod group 1, and a first boss 23 and a second boss 33 matched therewith, so that when a divergence occurs, the indicating rod can move rapidly when the pointed rail is subjected to an external thrust, thereby driving the first action plate group 2 or the second action plate group 3 to move rapidly, and then triggering the contact group 6 to disconnect the indicating circuit through the first matching portion 25 or the second matching portion 35. 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 inadequate divergence. 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 action plate group 2 and the second action plate group 3 can automatically reset when the passive driving force is lost, which is convenient for subsequent operation and maintenance. In addition, there are different ways to deal with divergence that occurs when the two pointed rails are in different states.

[0050] When the point rail is in the first normal state, the first point rail is in the close contact state, and the second point rail is in the repelling state, the upper first boss 23 is located in one of the first matching grooves 111, and the lower first boss 23 is located in one of the second matching grooves 121; when the divergence occurs, the first point rail and the second point rail both move, driving 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 to the outside of the first matching groove 111 under the action of the inclined surface of the first matching groove 111, and the lower first boss 23 moves to the outside of the second matching groove 121 under the action of the inclined surface of the second matching groove 121, and the movement of the two first bosses 23 The first action frame 22 is driven to move, and the first action frame 22 drives the first matching block 252 to move. The first abutment groove 2521 on the first matching block 252 cooperates with the first top wheel 62 on the first push rod 61. The first action frame 22 drives the first matching block 252 to move in the direction away from the first secondary action frame 26. The first top wheel 62 can abut against the side wall of the first abutment groove 2521, thereby driving the first top wheel 62 and the first push rod 61 to move in the direction away from the first matching block 252, realizing the displacement of the moving contact frame, so that the moving contact group and the static contact group in the contact group 6 are separated, thereby quickly cutting off the indication circuit, ensuring that the switch can disconnect the indication in time when the switch is squeezed.

[0051] When the point rail is in the second normal state, the first point rail is in the repulsive position, and the second point rail is in the close contact state, the upper second boss 33 is located in the other first matching groove 111, and the lower second boss 33 is located in the other second matching groove 121; when squeezing and diverging occur, the first point rail and the second point rail both move, driving the first indicating rod 11 and the second indicating rod 12 to move along their respective length directions, and the movement direction of the first indicating rod 11 and the second indicating rod 12 is opposite to the movement direction when the point rail is in the first normal state and squeezing and diverging occurs, so that the upper second boss 33 moves to the outside of the first matching groove 111 under the action of the inclined surface of the first matching groove 111, and the lower second boss 33 moves to the outside of the first matching groove 111 under the action of the inclined surface of the second matching groove 121 The lever 32 is moved downward to the outside of the second mating groove 121, and the movement of the two second bosses 33 drives the second action frame 32 to move, and the second action frame 32 drives the second mating block 352 to move, and the second abutting groove 3521 on the second mating block 352 cooperates with the second top wheel 64 on the second push rod 63, and the second action frame 32 drives the second mating block 352 to move in the direction 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 push rod 63 to move in the direction away from the second mating block 352, realizing the displacement of the moving contact frame, so that the moving contact group and the static contact group in the contact group 6 are separated, thereby quickly cutting off the indication circuit, ensuring that the switch can disconnect the indication in time when the switch is squeezed.
