[0030] This embodiment provides a rail transit bogie convenient for angle adjustment. As Figures 1-3 shown, this rail transit bogie convenient for angle adjustment includes a chassis 1, a support frame 2 is installed at the bottom of the chassis 1, and a runner 3 is movably arranged inside the support frame 2; a drive motor 4 is fixedly installed at the bottom of the chassis 1, and the output end of the drive motor 4 is fixedly connected to a rotating shaft 5; a support disk 7 is arranged at the top of the chassis 1, a connecting plate 10 is fixedly installed at the bottom of the support disk 7, and the top end of the rotating shaft 5 is fixedly connected to the bottom of the connecting plate 10; a top plate 8 for connecting with a jack is installed at the top of the support disk 7, and an installation groove 12 is opened at the bottom of the support disk 7, and a roller 13 is movably arranged inside the installation groove 12.

[0031] As an optional solution, the support frames 2 are symmetrically installed at the bottom of the chassis 1.

[0032] As an alternative solution, connection holes 9 fixedly connected to the jacks are symmetrically formed in the top plate 8.

[0033] In a specific implementation process, when using this rail transit bogie facilitating angle adjustment, after first fixedly connecting through the connection holes 9 with the jacks, when using the rail transit bogie facilitating angle adjustment to steer a vehicle, after placing the rotating wheels 3 on the track, the position of the underframe 1 can be moved through the cooperation of the rotating wheels 3. After the movement of the underframe 1 drives the top plate 8 to move to the bottom of the vehicle, the jacks will further move below the vehicle. After fixedly connecting the top of the jacks to the vehicle using connecting parts, when the drive motor 4 operates, it will drive the rotation of the rotating shaft 5. The rotation of the rotating shaft 5 will adjust the angle of the support disc 7. The rotation of the support disc 7 will drive the rotation of the top plate 8, and thus the angle of the vehicle can be adjusted for steering. When the support disc 7 rotates, at the same time, the rollers 13 rotate and support the support disc 7. When it is necessary to use the rail transit bogie to adjust the angle of the vehicle, the rail transit bogie in this embodiment facilitates the adjustment of the vehicle angle; at the same time, when maintaining the vehicle, changing the vehicle angle can facilitate the maintenance and improve the maintenance efficiency.

[0034] Embodiment 2

[0035] In order to further enhance the angle adjustment stability of this rail transit bogie facilitating angle adjustment, on the basis of Embodiment 1, in combination with Figures 1-3 , as an alternative solution, an annular groove 6 is provided at the top of the underframe 1, and a limiting ring 11 corresponding to the annular groove 6 is fixedly installed at the bottom of the support disc 7.

The purpose of the mounting grooves 12 is to accommodate the rollers 13. When arranged symmetrically, the rollers 13 can be symmetrically arranged in the mounting grooves 12, facilitating the support stability of the rollers for the support disc 7.

[0036] In a specific implementation process, when using the rail transit bogie facilitating angle adjustment, after first fixedly connecting with a jack through the connecting hole 9, when using the rail transit bogie facilitating angle adjustment to steer a vehicle, after placing the runner 3 on the track, the position of the chassis 1 can be moved through the cooperation of the runner 3. After the chassis 1 moves and drives the top plate 8 to move to the bottom of the vehicle, the jack will then move under the vehicle. After fixedly connecting the vehicle with a connecting piece at the top end of the jack, when the driving motor 4 works, it will drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 will adjust the angle of the support disc 7. The rotation of the support disc 7 will drive the top plate 8 to rotate, and thus the angle of the vehicle can be adjusted for steering. When the support disc 7 rotates, at the same time, the roller 13 rotates and supports the support disc 7. When the rail transit bogie with installation and adjustment effects adjusts the angle of the vehicle, it is convenient to adjust and maintain the angle of the vehicle.

[0037] On this basis, when the support disc 7 rotates, it will drive the limit ring 11 to rotate inside the annular groove 6. At the same time, the roller 13 will rotate inside the annular groove 6 to support the support disc 7, enabling the support disc 7 to rotate smoothly, and thus achieving the purpose of improving stability. When the rail transit bogie with installation and adjustment effects adjusts the angle of the vehicle, it can effectively avoid the vehicle from shaking, facilitating the adjustment and maintenance of the vehicle angle, and further improving the maintenance efficiency.

[0038] Embodiment 3

[0039] In order to further increase the stability of adjusting the vehicle angle, the position of the support disc 7 is positioned. On the basis of the above embodiment, in combination with Figure 4 , as an optional solution, a plurality of limit holes 14 are arranged in an array at the bottom of the support disc 7. The limit holes 14 are located on one side of the limit ring 11, and the support disc 7 provides an installation space for the limit holes 14. As an optional solution, two groups of support blocks 15 are fixedly installed inside the chassis 1. The support blocks 15 are located on one side of the annular groove 6

[0040] As an optional solution, a limit cylinder 16 is fixedly installed inside the support block 15, and a limit shaft 17 passes through the limit cylinder 16; an activity groove 18 is arranged inside the support block 15, and the limit cylinder 16 communicates with the activity groove 18; a sliding block 19 is arranged inside the activity groove 18, and the top of the sliding block 19 is fixedly connected to the bottom end of the limit shaft 17; a hydraulic cylinder 20 for fixing the support disc 7 is installed inside the chassis 1. The hydraulic cylinder 20 is fixedly arranged at the bottom of the support block 15, and the top end of the hydraulic cylinder 20 is fixedly connected to the bottom of the sliding block 19.

[0041] In a specific implementation process, when using this rail transit bogie facilitating angle adjustment, after being fixedly connected to a jack through the connection hole 9, when using the rail transit bogie facilitating angle adjustment to steer a vehicle, after placing the runner 3 on the track, the position of the underframe 1 can be moved through the cooperation of the runner 3. When the underframe 1 moves and drives the top plate 8 to move under the vehicle, the jack will then move under the vehicle. After fixedly connecting the top of the jack to the vehicle using a connecting piece, when the drive motor 4 operates, it will drive the rotation of the rotating shaft 5. The rotation of the rotating shaft 5 will adjust the angle of the support disc 7. The rotation of the support disc 7 will drive the rotation of the top plate 8, and thus the angle of the vehicle can be adjusted for steering. When the support disc 7 rotates, the roller 13 rotates simultaneously and supports the support disc 7. When the rail transit bogie with installation adjustment effect adjusts the angle of the vehicle, it is convenient to adjust and maintain the angle of the vehicle.

[0042] On this basis, after the support disc 7 rotates to adjust the vehicle angle to a predetermined position, the operation of the hydraulic cylinder 20 will push the sliding block 19 to move. The movement of the sliding block 19 will push the limit shaft 17 to move into the limit hole 14, and thus the position of the support disc 7 will be positioned, achieving the purpose of improving stability.

[0043] Regarding the above embodiments, it should be noted that the specific model specifications of the drive motor 4 in the above embodiments 1-3 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technologies in this field. The above devices that require power supply are all existing technologies, and their principles and connection methods to the power supply are clear and easy to implement for those skilled in the art. Therefore, they will not be elaborated in detail here.

[0044] The above are only the preferred embodiments of the utility model patent, and do not constitute a limitation to the utility model patent. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model patent shall be included within the protection scope of the utility model patent.
