[0030] See also Figure 1In an embodiment of the present application, a rail wheel set support bracket 10 is provided, and the rail wheel set support bracket 10 can be used to install an axle 11, and the axle 11 is used for installing a roller. When the roller is installed on the axle 11, and the axle 11 is installed on the rail wheel set support bracket 10, the axle 11 remains in a stable state, and the roller can rotate relative to the axle 11 to achieve the purpose of rolling. Among them, the rail wheel set support bracket 10 can be applied to a movable frequency converter, and the rail wheel set support bracket 10 and the movable frequency converter using the rail wheel set support bracket 10 can improve the technical problem of inconvenient assembly and disassembly of rollers in the rail wheel set in the prior art.

[0031] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The rail wheel group support bracket 10 includes a bracket body 100, a reinforcement structure 200 and a closure member 201. A first U-shaped groove 110 is provided at one end of the bracket body 100. It is worth noting that the opening position of the first U-shaped groove 110 is the same as the position of the mounting hole for mounting the wheel shaft 11 on the bracket in the prior art, and will not be repeated here. However, in the present embodiment, the opening direction of the first U-shaped groove 110 is perpendicular to the extension direction of the bracket body 100, and after the bracket body 100 is assembled in the movable inverter, the opening of the first U-shaped groove 110 is set downward. The reinforcement structure 200 is arranged on one side of the bracket body 100, and a second U-shaped groove 202 is provided on the reinforcement structure 200; the second U-shaped groove 202 is arranged to coincide with the inner wall contour of the first U-shaped groove 110, and together form an open groove 111 for the wheel shaft 11 to be installed. In other words, when the reinforcing structure 200 is connected to the bracket body 100, the reinforcing structure 200 and the bracket body 100 can be regarded as a whole, and the first U-shaped groove 110 and the second U-shaped groove 202 can be regarded as a complete groove, that is, the open groove 111. The closing member 201 is detachably connected to the reinforcing structure 200, and the closing member 201 closes the opening of the second U-shaped groove 202 to close the open groove 111.

[0032] As described above, when assembling the axle 11, the axle 11 is loaded into the opening of the open groove 111, that is, the axle 11 is loaded into the first U-shaped groove 110 and the second U-shaped groove 202 at the same time, and then the closing member 201 is connected to the reinforcing structure 200, so that the closing member 201 closes the second U-shaped groove 202, and the opening groove 111 can be closed, thereby realizing the assembly of the axle 11. It can be seen that when assembling the axle 11, the track wheel group support bracket 10 reduces the assembly difficulty of the axle 11 and can improve the assembly efficiency of the axle 11. In addition, when the axle 11 needs to be removed, it is only necessary to remove the closing member 201 from the reinforcing structure 200 so that the open groove 111 is opened, and the axle 11 can be directly taken out from the open groove 111, thereby reducing the disassembly difficulty of the axle 11 and improving the disassembly efficiency. Based on this, the track wheel group support bracket 10 provided in this embodiment can improve the technical problem of inconvenient disassembly and assembly of rollers in the track wheel group in the prior art.

[0033] In addition, since the reinforcement structure 200 is provided on the bracket body 100, the overall strength of the bracket body 100 can be improved by the reinforcement structure 200, thereby ensuring that the overall stability of the rail wheel set supporting bracket 10 is improved, and providing a stable support effect for the rail wheel set.

[0034] It is worth noting that when the closure member 201 is connected to the reinforcing structure 200 and the axle 11 is inserted into the opening groove 111, the axle 11 contacts the inner wall of the opening groove 111. At the same time, the axle 11 contacts the closure member 201 to enhance the assembly stability of the axle 11 and prevent the axle 11 from moving in its radial direction.

[0035] Optionally, in this embodiment, mounting holes 221 are provided on both side walls of the second U-shaped groove 202, and the mounting holes 221 penetrate the side walls of the second U-shaped groove 202; the closing member 201 is a latch, and the latch passes through the two mounting holes 221 to be detachably connected to the reinforcing structure 200. The closing member 201 is set as a latch, and the closing of the open groove 111 is achieved by inserting the latch into the mounting holes 221, thereby achieving the assembly of the wheel axle 11, which is simple to operate and easy to disassemble and assemble. At the same time, the cost of the latch is low and it is easy to replace, which is conducive to reducing the overall cost.

[0036] It should be understood that in other embodiments of the present application, the closing member 201 may also be provided in other forms. For example, the closing member 201 is a buckle structure detachably connected to the reinforcing structure 200, and is connected to the reinforcing structure 200 by a buckle connection, thereby closing the opening slot 111 and assembling the axle 11.

[0037] Optionally, in this embodiment, the reinforcement structure 200 is welded to the bracket body 100, or the reinforcement structure 200 is integrally formed with the bracket body 100. The reinforcement structure 200 is fixedly connected to the bracket body 100 by welding, which is simple to operate and easy to perform. Alternatively, in other embodiments, the reinforcement structure 200 is integrated into the bracket body 100 by integral molding, and the step of connecting the reinforcement structure 200 to the bracket body 100 can be omitted, reducing the steps of assembling the track wheel support bracket 10 to the movable inverter, thereby improving assembly efficiency.

[0038] In addition, in this embodiment, the thickness of the bracket body 100 is the same as the thickness of the reinforcement structure 200. It is worth noting that the bracket body 100 and the reinforcement structure 200 are both in the shape of a plate, and the thickness of the bracket body 100 and the thickness of the reinforcement structure 200 are set to be the same, which is conducive to the simultaneous production of the bracket body 100 and the reinforcement structure 200, thereby improving the production efficiency.

[0039] Of course, in order to enhance the reinforcing effect on the bracket body 100 , the thickness of the reinforcing structure 200 may be set to be greater than the thickness of the bracket body 100 ; or, a plurality of reinforcing structures 200 may be provided on the bracket body 100 .

[0040] Optionally, in this embodiment, the reinforcement structure 200 includes a main body 210 and two legs 220, the two legs 220 are arranged on the main body 210 at intervals, and a second U-shaped groove 202 is formed between the two legs 220; the closing piece 201 is connected to the two legs 220 to close the second U-shaped groove 202. Among them, the mounting holes 221 are opened on the legs 220, and the closing piece 201 is connected to the legs 220 by passing through the mounting holes 221. Further, the outer contour of the main body 210 is located outside the outer contour of the bracket body 100, which can improve the overall strength of the reinforcement structure 200, thereby improving the reinforcement effect on the bracket body 100; in addition, the outer contour of the legs 220 is located inside the outer contour of the bracket body 100, which can prevent the legs 220 from being affected by other components, ensure the overall safety of the legs 220, ensure the stability of the closing piece 201, and then ensure the installation stability of the axle 11.

[0041] In this embodiment, the rail wheel set support bracket 10 further includes a limiting structure 300, which is arranged on a side of the bracket body 100 away from the reinforcement structure 200, and the limiting structure 300 is arranged around the first U-shaped groove 110. The limiting structure 300 is arranged on the side of the bracket body 100 away from the reinforcement structure 200 to prevent the rail wheel set from axial movement during operation. The limiting structure 300 is fixed to the bracket body 100 by welding. In addition, the limiting structure 300 is arranged around the first U-shaped groove 110 to avoid the limiting structure 300 from affecting the installation of the wheel axle 11.

[0042] Furthermore, the limiting structure 300 is bent into an arc shape that matches the arc segment of the first U-shaped groove 110. In other words, the inner side wall of the limiting structure 300 and the inner side wall of the first U-shaped groove 110 can be regarded as an integral arc surface.

[0043] Based on the above-mentioned track wheel set support bracket 10, a movable frequency converter (not shown) is also provided in this embodiment, and the movable frequency converter adopts the above-mentioned track wheel set support bracket 10. It is worth noting that the movable frequency converter has a wheel axle 11 and a roller, and the wheel axle 11 is connected to the track wheel set support bracket 10, that is, the wheel axle 11 is installed in the open groove 111, and the closing member 201 closes the open groove 111 to achieve the cooperation with the track wheel set support bracket 10; the roller is assembled on the wheel axle 11.

[0044] In summary, when assembling the track wheel set in the movable frequency converter, the wheel axle 11 is installed along the opening of the opening groove 111, so that the wheel axle 11 is installed in the first U-shaped groove 110 and the second U-shaped groove 202 at the same time. However, the closure 201 is connected to the reinforcing structure 200, so that the installation of the wheel axle 11 can be achieved, which reduces the difficulty of assembly. When it is necessary to disassemble the roller, the closure 201 is removed from the reinforcing structure 200, and the opening groove 111 is opened, so that the wheel axle 11 can be easily taken out from the opening groove 111, which reduces the difficulty of disassembly. Based on this, the technical problem of inconvenient assembly and disassembly of the roller in the track wheel set in the prior art can be improved. In addition, since the reinforcing structure 200 is provided on the bracket body 100, the overall strength of the bracket body 100 can be improved by the reinforcing structure 200, thereby ensuring that the overall stability of the track wheel set supporting the bracket 10 is improved, and a stable support effect can be provided to the track wheel set.
