[0051] In this embodiment, by setting a mobile frame 10 that can move relative to the straight rail 2 8, the first point rail 2 and the second point rail 4 can be driven to move synchronously, realizing the rapid conversion between the straight double-gauge track and the turning single-gauge track, greatly improving the efficiency of track conversion, reducing the time required for conversion, and meeting the rapid switching of different track operation requirements. A plurality of swing members 13 are rotatably arranged on a bracket 12 fixed relative to the straight rail 2 8, and one end of a swing member 13 is hinged to the mobile frame 10, a plurality of slide bars 14 are parallelly slidably arranged on the bracket 12 and hinged to the swing member 13, and the third point rail 5 and the fourth point rail 7 are respectively slidably hinged to a swing member 13 through a connecting member 15. By sliding and hingedly connecting a plurality of different swing members 13 at the same time, the number of driving members 24 is reduced, the installation conditions on site are reduced, the number of driving members 24 is reduced, the labor intensity is reduced, and the accident rate is reduced. During the track conversion process, the actions of each point rail can cooperate with each other and be linked at the same time, and the plurality of point rails will be performed simultaneously when they are in action, thereby improving the efficiency of track change. Different swinging members 13 are arranged on opposite sides, and different swinging directions are achieved by different installation directions of the swinging members 13, so that the fourth point rail 7 and the third point rail 5 are opened on opposite sides, ensuring that one of the third point rail 5 and the fourth point rail 7 is always close to the curved rail 2 9, ensuring the safety of driving. When switching, the various components of the conversion device cooperate with each other, and the moving frame 10, the bracket 12, the swinging member 13, the sliding rod 14 and the connecting member 15 work together to enable the track to maintain a stable structure during the conversion process. This stability helps to reduce the wear and deformation of the track, extend the service life of the track, and improve the reliability of the entire track system.

[0052] As a further technical solution, it also includes: there are several connecting rods 16, the movable frame 10 and the connecting member 15 are connected to the swing member 13 through the connecting rods 16, and the connecting rods 16 include: a threaded rod 17 is arranged on the connecting rod 16; a sleeve 18 is slidably arranged on the threaded rod 17; there are several limit bolts 19, which are rotatably arranged on the threaded rod 17, and the several limit bolts 19 are used to limit the position of the sleeve 18.

[0053] In this embodiment, the adjustable connecting rod 16 structure brings convenience to the installation and commissioning of the device. During the installation process, the staff can use the adjustability of the connecting rod 16 as a further technical solution, and the conversion device can be applied to more rail turnouts of different specifications and types. Whether it is a track with different track gauges or a track turn with special requirements, a good track conversion effect can be achieved by adjusting the length of the connecting rod 16.

[0054] As a further technical solution, the first swing member 13, the second swing member 13 and the third swing member 13 have the same structure, and also include: there are several connecting rods 16, the movable frame 10 and the connecting member 15 are connected to the swing member 13 through the connecting rod 16, and the connecting rod 16 includes: a threaded rod 17 is arranged on the connecting rod 16; a sleeve 18 is slidably arranged on the threaded rod 17, and the sleeve 18 slides close to or away from the threaded rod 17; there are several limit bolts 19, which are threaded on the threaded rod 17, and the several limit bolts 19 are used to limit the position of the sleeve 18.

[0055] In this embodiment, the cross bar 20 in the swing member 13 cooperates with the slide bar 14 to provide a stable support foundation for the entire swing structure. The intermediate rod 21 is arranged on the cross bar 20 and is not parallel to the cross bar 20. This unique design makes the mechanical transmission more reasonable and efficient. During the track conversion process, the force can be transmitted to each related component through the cross bar 20 and the intermediate rod 21 in a more optimized path to ensure that the movement of the point rail is accurate and powerful. The design of the intermediate rod 21 being hinged to the swing member 13 and the connecting member 15 increases the diversity and flexibility of the connection. This articulation method makes the movement between the various components more coordinated and can adapt to different track conversion situations.

[0056] As a further technical solution, it also includes: one end of the sliding sleeve 22 is hinged to the sleeve 18, and the other end is slidably set on the swing member 13, and the connecting member 15 and the movable frame 10 are hinged to the swing member 13 through the sliding sleeve 22.

[0057] In this embodiment, the provision of the sliding sleeve 22 enhances the stability of the connection. One end is hinged to the sleeve 18, and the other end is slidably provided on the swinging member 13, so that the connection between the connecting member 15 and the movable frame 10 and the swinging member 13 through the sliding sleeve 22 is more firm and reliable. During the track conversion process, this connection method can withstand greater forces and vibrations, and reduce the probability of failures caused by loose connections. The design of the sliding sleeve 22 makes the device more flexible during installation and use. It can adapt to different installation angles and space restrictions, and is convenient for staff to install and debug. At the same time, during track maintenance and adjustment, the state of the device can also be quickly adjusted by sliding the sliding sleeve 22, thereby improving maintenance efficiency.

[0058] As a further technical solution, it also includes: a driving member 24 is arranged on the bracket 12; two ends of a transmission rod 25 are respectively arranged on the driving member 24 and the moving frame 10, and the driving member 24 drives the moving frame 10 to move through the transmission rod 25.

[0059] In this embodiment, the arrangement of the driver 24 and the transmission rod 25 enables the conversion device to realize automatic control. The driver 24 can receive external signals and accurately control the movement of the mobile frame 10, thereby realizing fast and accurate conversion of the track. This greatly improves the efficiency of track conversion and reduces the error and labor intensity of manual operation. The driver 24 provides a stable power source for the movement of the mobile frame 10. Compared with traditional manual operation, the driver 24 can output greater force to ensure that the mobile frame 10 can move smoothly under various working conditions. At the same time, the transmission rod 25 can accurately transmit the power of the driver 24 to the mobile frame 10, reducing power loss and improving the reliability of the device. By arranging the driver 24 on the bracket 12, centralized control and management can be conveniently carried out. The driver 24 of multiple conversion devices can be connected to a central control system to realize unified scheduling and monitoring of track conversion of the entire railway network. This not only improves management efficiency, but also can timely discover and handle faults to ensure the safety and smoothness of railway transportation.

[0060] As a further technical solution, it also includes: a length adjusting member 26 is arranged on the slide rod 14, and the length adjusting member 26 is used to adjust the length of the slide rod 14.

[0061] In this embodiment, the length adjustment member 26 is arranged on the slide bar 14, so that the length of the slide bar 14 can be used as a further technical solution. The accuracy of track conversion is crucial. By accurately adjusting the length of the slide bar 14, it is possible to ensure that the movements of each pointed rail during the conversion process are coordinated, reduce errors and jamming, and improve the stability and reliability of track conversion. When installing the conversion device, the length adjustment member 26 can help the staff quickly adjust the length of the slide bar 14 to adapt it to different installation spaces and track conditions. This greatly simplifies the installation process and improves installation efficiency.

[0062] As a further technical solution, it also includes: a plurality of cleaning brushes 27, which are respectively raised and lowered between the first point rail 2 and the straight rail 6, between the second point rail 4 and the third point rail 5, and between the fourth point rail 7 and the curved rail 9. The cleaning brushes 27 are used to clean impurities and dust on the sleepers.

[0063] In this embodiment, the cleaning brush 27 disposed at a specific position can clean the impurities and dust on the sleeper in time. During the track switching process, if these impurities and dust are not cleaned in time, they may affect the coordination between the point rail and the sleeper, resulting in an unsmooth switching or even a jamming phenomenon. The presence of the cleaning brush 27 effectively avoids this situation, ensures the smooth progress of the track switching, and improves the efficiency and reliability of the track switching.

[0064] As a further technical solution, it also includes: there are several fixed seats 28, which are arranged on the straight rail three 1, the first point rail 2, the second point rail 4, the third point rail 5, the straight rail one 6, the straight rail two 8, the fourth point rail 7 and the curved rail two 9; there are several first swing rods 29, which are respectively hinged on the fixed seats 28 of the straight rail three 1, the straight rail one 6, the straight rail two 8 and the curved rail two 9; there are several second swing rods 30, which are respectively hinged on other fixed seats 28, and the adjacent first swing rods 29 and the second swing rods 30 are hinged; the lifting rod 31 is hinged on the first swing rod 29 or the second swing rod 30, the cleaning brush 27 is arranged on the lifting rod 31, and the lifting rod 31 is used to drive the cleaning brush 27 to rise and fall.

[0065] In this embodiment, the combination structure of the fixed seat 28, the first swing arm 29, the second swing arm 30 and the lifting rod 31 can achieve precise control of the lifting and lowering of the cleaning brush 27. When the sleeper needs to be cleaned, the lifting rod 31 can accurately lower the cleaning brush 27 to a suitable position for cleaning; after the cleaning is completed, the cleaning brush 27 can be reliably raised to avoid interference with the track operation. This precise control ensures the efficiency and reliability of the cleaning work, and also improves the overall performance of the track conversion device. The fixed seat 28 firmly connects each component to the track to ensure the stability of the entire device during operation. The hinged design of the first swing arm 29 and the second swing arm 30 and the cooperation with the lifting rod 31 enable the device to move more flexibly when subjected to external force and vibration, reducing the risk of damage to the components. This structural design improves the durability of the device, extends its service life, and reduces maintenance costs.

[0066] As a further technical solution, it also includes: a plurality of limit blocks 32 are arranged on the sleeper, and the limit blocks 32 are used to limit the position of the lifting rod 31.

[0067] In this embodiment, the limit block 32 can limit the position of the lifting rod 31 to prevent the lifting rod 31 from tipping over or deflecting, thereby ensuring that cleaning can be carried out normally.

[0068] As a further technical solution, the bristles of the cleaning brush 27 are elastic.

[0069] In this embodiment, the elastic bristles can clean dust from a larger area and ensure a smoother cleaning process, thereby improving the cleaning effect and quality.
