[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0020] Example 1: Please refer to Figures 1 to 2 A rail axle box with a cable support structure includes a rail 1, an axle 2, a wheel 3, and a drive motor 4. The wheel 3 is mounted on the rail 1, and the axle 2 is connected to the wheel 3. The drive motor 4 is mounted on one side of the axle 2. The wheel 3 is provided with a fixing component 5, a rotating component 6, and a support component 7. The fixing component 5 is mounted on both sides of the wheel 3, the rotating component 6 is mounted on the fixing component 5, and the support component 7 is mounted on the rotating component 6.

[0021] The fixing bracket 501 in the fixing component 5 is set at both ends of the axle 2, and the fixing plate 502 is fixedly installed at the end of the fixing bracket 501.

[0022] In use, the track 1 provides the running trajectory for the wheels 3, the drive motor 4 drives the axle 2 to rotate, the fixing bracket 501 in the fixing component 5 is installed on both ends of the axle 2, and the fixing plate 502 at the end is used to connect the subsequent structure. The fixing component 5 is firmly set on both sides of the wheels 3, providing basic support for the entire cable support structure, ensuring that the subsequent rotating component 6 and bracket component 7 can work stably during the operation of the railcar, and ensuring that the cable support structure will not loosen or shift due to factors such as vibration of the vehicle, thus providing a stable foundation for the fixing of the cable.

[0023] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The fixed base 601 in the rotating assembly 6 is fixedly mounted on the fixed plate 502. A sleeve 602 is fixedly mounted inside the fixed base 601, and a fixing hole 603 is provided on the sleeve 602.

[0024] The rotating assembly 6 has a sleeve 602 with a rotating shaft 604 embedded inside it, and the rotating shaft 604 has positioning holes 605 evenly arranged on it.

[0025] In use, the fixing base 601 is fixed on the fixing plate 502. The internal sleeve 602 and the embedded rotating shaft 604 cooperate with each other. When it is necessary to adjust the angle of the cable bracket, it can be achieved by rotating the rotating shaft 604. The fixing holes 603 on the sleeve 602 and the evenly distributed positioning holes 605 on the rotating shaft 604 can be fixed by inserting positioning pins after adjusting to a suitable angle. Under different operating conditions of the railcar, the cable needs to be routed in different directions. At this time, the angle of the cable bracket can be flexibly adjusted through this structure to meet the cable layout requirements and improve the convenience of cable installation and maintenance.

[0026] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The cable bracket 701 in the bracket assembly 7 is fixedly mounted on the rotating shaft 604, and a hanging protrusion 702 is provided on one end of the cable bracket 701.

[0027] The top of the fixing strip 703 in the bracket assembly 7 is provided with a handle 704, and the bottom of the fixing strip 703 is provided with a fixing protrusion 705. A spring 706 is sleeved on the fixing protrusion 705. One end of the spring 706 is fixedly mounted on the sleeve 602, and the other end of the spring 706 is fixedly mounted on the bottom of the fixing strip 703.

[0028] In use, the cable bracket 701 is fixed on the rotating shaft 604. The suspension protrusion 702 on one end of the bracket can be used to suspend the cable. After the angle of the rotating shaft 604 is adjusted, if the current angle is to be fixed, it can be achieved by operating the fixing bar 703. Pull the handle 704 upward, and the fixing protrusion 705 at the bottom of the fixing bar 703 will move upward, stretching the spring 706. After the angle is adjusted, release the handle 704. Under the elastic force of the spring 706, the fixing protrusion 705 will be inserted into the corresponding positioning hole 605 on the rotating shaft 604, quickly locking the rotating shaft 604, so that the cable bracket 701 is kept at the required angle and stably supports the cable.
