[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] like Figures 1-4 As shown, this embodiment provides a turnout assembly for rail transit, including: a beam 10, a trolley 20, and a drive assembly. One end of the beam 10 is rotatably connected to the ground via a rotating shaft 11, and the other end of the beam 10 is selectively connected to one of a plurality of tracks 1. The trolleys 20 are configured to be movably disposed on the ground, and the plurality of trolleys 20 are respectively connected to the beam 10. The plurality of trolleys 20 are respectively adapted to move around the axis of the rotating shaft 11. The drive assembly is connected to the ground and has a movable drive part, which is rotatably connected to the beam 10.

[0026] In some embodiments, one end of the beam 10 is rotatably connected to the ground via a rotating shaft 11, and the beam 10 can rotate around the rotating shaft 11. The other end of the beam 10 can selectively dock with one of a plurality of tracks 1, thereby enabling the train to switch between different track 1 lines.

[0027] Multiple trolleys 20 are configured, and each trolley 20 is movably mounted on the ground. Each trolley 20 is connected to the beam 10 and can move around the axis of the rotation shaft 11. The function of the trolley 20 is to support the beam 10 and assist the beam 10 in rotating and adjusting its position under the action of the drive assembly. The drive assembly is connected to the ground and has a movable drive unit that is rotatably connected to the beam 10. The movement of the drive unit pushes the beam 10 to rotate around the rotation shaft 11, thereby realizing the switching function of the turnout.

[0028] It is understandable that the beam 10 is rotatably connected to the ground via the rotating shaft 11. When the drive unit of the drive assembly moves, it will apply a force to the beam 10. Since one end of the beam 10 is fixed on the rotating shaft 11, the beam 10 will rotate around the rotating shaft 11, thereby changing the docking state of the other end of the beam 10 with different tracks 1.

[0029] The trolley 20 moves on the ground and is connected to the beam 10. When the beam 10 rotates under the action of the drive assembly, the trolley 20 moves around the axis of the rotation shaft 11 as the beam 10 rotates. The movement of the trolley 20 provides support and guidance for the beam 10, ensuring the stability and balance of the beam 10 during rotation. At the same time, the combined action of multiple trolleys 20 disperses the weight and force borne by the beam 10, enabling the turnout assembly to withstand a large load.

[0030] The drive unit of the drive assembly is rotatably connected to the beam 10. When the drive assembly is activated, the drive unit moves in a predetermined direction and distance. The force generated by the movement of the drive unit is transmitted to the beam 10, causing the beam 10 to rotate over various resistances (such as friction and inertia). It should be noted that the drive assembly is typically powered by a power source (such as a motor or hydraulic system), which converts the power into linear motion of the drive unit through a mechanical transmission mechanism (such as a lead screw, rack and pinion), thereby driving the beam 10.

[0031] According to the present invention, a turnout assembly for rail transit drives a beam 10 to rotate around a rotating shaft 11 via a drive assembly, enabling the other end of the beam 10 to selectively connect with different tracks 1, thus realizing the switching of trains between different track 1 lines. Moreover, multiple trolleys 20 provide stable support and guidance for the beam 10, reducing the swaying and offset of the beam 10 during rotation, ensuring the accuracy and reliability of turnout switching. At the same time, the presence of multiple trolleys 20 also distributes the weight and force borne by the beam 10, reducing the risk of damage to the beam 10 and related components, improving the overall stability and service life of the turnout assembly, thereby ensuring the safety of train operation.

[0032] According to some embodiments of the present invention, the trolley 20 includes a trolley body 21, and roller assemblies 22 are respectively provided at both ends of the bottom of the trolley body 21. The roller assemblies 22 are adapted to contact the ground.

[0033] In some embodiments, the trolley body 21 serves as the main load-bearing structure of the trolley 20, providing a basic frame and support for the entire trolley 20 to bear the weight transmitted from the beam 10 and various forces encountered during movement, such as rolling friction and lateral forces.

[0034] The roller assembly 22 at both ends of the trolley body 21 can keep the trolley 20 balanced during movement, avoiding tilting or overturning due to uneven force on one side. At the same time, it helps the trolley 20 to move more stably along the predetermined arc path when moving around the axis of rotation 11, ensuring the smoothness of the rotation of the beam 10.

[0035] It should be noted that by using the rolling friction between the roller assembly 22 and the ground, the sliding friction between the trolley 20 and the ground is converted into rolling friction, which greatly reduces the moving resistance and makes the trolley 20 move more easily on the ground. This not only improves the moving efficiency of the trolley 20, but also reduces energy loss and reduces wear and tear on the ground and the trolley 20 itself.

[0036] According to some embodiments of the present invention, the roller assembly 22 includes a connecting plate 221, which is connected to the trolley body 21. A bracket is connected to the side of the connecting plate 221 away from the trolley body 21. The bracket is rotatably connected to the roller body 225. The line connecting the center of the roller body 225 and the axis of the rotating shaft 11 is perpendicular to the diameter of the roller body 225.

[0037] In some embodiments, the connecting plate 221 serves as a connecting component between the roller assembly 22 and the trolley body 21, transmitting force and fixing the position of the roller assembly 22. By reliably connecting the connecting plate 221 to the trolley body 21, it is ensured that the roller assembly 22 can move together with the trolley body 21 and can withstand the weight and various forces transmitted from the trolley body 21, thus ensuring the stability of the roller assembly 22 during operation.

[0038] The bracket provides a mounting base for the roller body 225, allowing the roller body 225 to rotate relative to the bracket, thereby achieving rolling friction between the roller body 225 and the ground and reducing the moving resistance of the trolley 20.

[0039] The line connecting the center of the roller body 225 to the axis of rotation 11 is perpendicular to the diameter, ensuring that the movement trajectory of the roller body 225 conforms to expectations when the trolley 20 moves around the axis of rotation 11. Specifically, when the line connecting the center of the roller body 225 to the axis of rotation 11 is perpendicular to the diameter of the roller body 225, the roller body 225 can better adapt to the arc path during movement, reducing lateral forces and unnecessary wear caused by angular deviations, making the trolley 20 move more smoothly and improving the overall performance of the turnout assembly.

[0040] According to some embodiments of the present invention, the bracket includes a horizontal plate 222, which is connected to a connecting plate 221. Vertical plates 223 extending away from the connecting plate 221 are respectively provided at both ends of the horizontal plate 222. A connecting rod 224 is provided between the two vertical plates 223, and a roller body 225 is rotatably sleeved on the connecting rod 224.

[0041] In some embodiments, the horizontal plate 222 is connected to the connecting plate 221, fixing the entire bracket in the roller assembly 22, thereby forming a stable connection structure with the trolley body 21. Vertical plates 223 extending away from the connecting plate 221 are respectively provided at both ends of the horizontal plate 222. The main function of the two vertical plates 223 is to provide an installation position for the connecting rod 224 and to enhance the overall structural strength of the bracket. The connecting rod 224 between the two vertical plates 223 is the basis for the rotation of the roller body 225. The roller body 225 is rotatably fitted onto the connecting rod 224, forming a rotational connection with the bracket through the connecting rod 224. Therefore, when the trolley 20 moves, the roller body 225 rotates around the connecting rod 224 under the action of ground friction, achieving rolling friction and reducing the moving resistance of the trolley 20.

[0042] According to some embodiments of the present invention, the horizontal plate 222 is provided with two first mating holes that penetrate in the thickness direction, and the connecting plate 221 is provided with two second mating holes that are directly opposite to the two first mating holes. The bolt 226 passes through the first mating holes and the corresponding second mating holes and is connected to the nut to connect the horizontal plate 222 and the connecting plate 221.

[0043] In some embodiments, two first mating holes penetrating the thickness of the horizontal plate 222 are provided on the horizontal plate 222, and two second mating holes opposite to it are provided on the connecting plate 221. After the two bolts 226 are respectively mated with the corresponding first mating holes and second mating holes, the connection accuracy and stability of the horizontal plate 222 and the connecting plate 221 can be guaranteed, avoiding the horizontal plate 222 from rotating relative to the connecting plate 221 and causing the position of the roller body 225 to shift, thereby ensuring the position accuracy of the roller body 225, and thus ensuring that the trolley 20 can move stably along the axis of the rotating shaft 11 with the axis as the center.

[0044] According to some embodiments of the present invention, the roller assembly 22 further includes a surrounding plate 227, the top of which is connected to the trolley body 21, the bottom of which is open, a connecting plate 221 which is disposed inside the surrounding plate 227 and welded to the surrounding plate 227, and at least a portion of the roller body 225 which is located outside the surrounding plate 227.

[0045] In some embodiments, the top of the enclosure 227 is connected to the trolley body 21, and the connecting plate 221 is disposed inside the enclosure 227 and welded to the enclosure 227. On the one hand, this enhances the integrity and stability of the internal structure of the roller assembly 22 (welding is a high-strength connection method that enables the connecting plate 221 and the enclosure 227 to be tightly combined and jointly withstand various forces and vibrations generated during the movement of the trolley). On the other hand, the enclosure 227 provides a certain degree of protection for the connecting plate 221, the bracket, and the roller body 225, thereby reducing the erosion and damage to the connecting plate 221, the bracket, the bolts 226, and the roller body 225 by the external environment, and extending the service life of the connecting plate 221, the bracket, the bolts 226, and the roller body 225.

[0046] Of course, the roller body 225 is located at least partially outside the enclosure 227 in order to ensure that the roller body 225 can directly contact the ground and realize the rolling friction function.

[0047] According to some embodiments of the present invention, a plurality of adjusting shims 228 are provided between the horizontal plate 222 and the connecting plate 221.

[0048] In some embodiments, the main function of the adjusting shims 228 is to adjust the distance and relative position between the horizontal plate 222 and the connecting plate 221. Specifically, due to possible errors during manufacturing and installation, the actual distance and position between the horizontal plate 222 and the connecting plate 221 may deviate from the design requirements. Therefore, by increasing or decreasing the number of adjusting shims 228, this application can precisely adjust the distance between the horizontal plate 222 and the connecting plate 221, so that the roller assembly 22 achieves an ideal installation state, thereby enabling the trolley 20 to stably support the beam 10 so that the position of the beam 10 conforms to the preset standard.

[0049] It should be noted that the adjusting shim 228 also serves as a buffer and shock absorber. Specifically, during the movement of the trolley 20, various vibrations and impacts will be generated. The adjusting shim 228 can absorb and disperse these forces, reduce the direct impact on the horizontal plate 222 and the connecting plate 221, protect the connecting parts, and extend the service life of the horizontal plate 222 and the connecting plate 221.

[0050] Understandably, using multiple adjusting shims 228 allows for more flexible adjustments based on actual needs. Specifically, different thicknesses and combinations of adjusting shims 228 can achieve different adjustment effects, meeting installation requirements under different working conditions. For example, when a larger adjustment is required, the number of adjusting shims 228 can be increased or thicker shims can be used; when only fine adjustments are needed, thinner adjusting shims 228 can be used or the number of adjusting shims 228 can be reduced.

[0051] According to some embodiments of the present invention, a rotary bearing 229 is provided between the roller body 225 and the connecting rod 224. In some embodiments, the inner ring of the rotary bearing 229 is sleeved on the outer circumference of the connecting rod 224, and the outer ring of the rotary bearing 229 is adapted to connect with the roller body 225. The provision of the rotary bearing 229 significantly reduces the frictional resistance between the roller body 225 and the connecting rod 224, making the trolley 20 move more easily, reducing energy consumption, and improving moving efficiency. At the same time, the lower frictional resistance also helps to reduce the wear of the roller body 225 and the connecting rod 224, extending the service life of the roller body 225 and the connecting rod 224.

[0052] According to some embodiments of the present invention, multiple mounting plates 40 are provided on the ground, each corresponding to one of the multiple trolleys 20, and the trolleys 20 are movably mounted on the corresponding mounting plates 40.

[0053] In some embodiments, the ground conditions in the turnout area of ​​track 1 are complex, and there may be problems such as unevenness and debris. Directly moving the trolley on the ground can lead to problems such as unstable operation and accelerated wear. Therefore, setting up the mounting plate 40 on the ground can provide the trolley 20 with a stable and flat moving base (the mounting plate 40 can be specially treated to ensure the flatness and hardness of the surface of the mounting plate 40, providing a good moving environment for the trolley).

[0054] According to some embodiments of the present invention, the drive assembly includes a fixed base 31, which is connected to the ground. A movable push rod 32 is provided on the fixed base 31. The free end of the push rod 32 is rotatably connected to the beam 10. The push rod 32 is configured as a drive unit.

[0055] In some embodiments, a power unit is also provided on the fixed base 31. The power unit can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder, etc., and there is no limitation here. The operation of the power unit can drive the push rod 32 to move. Through the movement of the push rod 32 and the rotational connection between the push rod 32 and the beam 10, the moving distance and direction of the beam 10 can be precisely controlled, thereby realizing the precise switching of the turnout.

[0056] In some embodiments, the trolley body 21 is integrally welded from Q460qENH sheet metal. The thickness of the two main web plates of the trolley body 21 is 25mm, and the thickness of the intermediate web plate is 20mm. The web plates are connected by vertical plates and reinforcing ribs. While meeting strength requirements, the upper part between the two main web plates is not covered with a steel plate. Drainage holes are provided on the vertical plates and web plates to solve problems such as rainwater drainage, saving materials and reducing the weight of the trolley body 21. Oval holes are provided at appropriate positions on some of the main web plates of the trolley body 21 to allow for quick application of bearing lubricating grease to the roller assemblies 22 at different angles without disassembling the roller assemblies 22.
