[0007] Although the above two documents disclose a rotating platform for turning the shuttle bus, both documents may fail to rotate properly during operation, and no solution is given in both documents. Summary of the invention

[0008] In order to solve the problem of misalignment between the connecting track and the track that needs to be connected after the revolving platform rotates, the present application provides a revolving platform positioning device for a ferry bus, which achieves the effect of aligning the connecting track and the track that needs to be connected after the revolving platform rotates through a straightening column and a guiding mechanism on the straightening column.

[0009] The present application provides a rotary platform positioning device for a shuttle bus adopts the following technical solution:

[0010] A rotating platform positioning device for a shuttle bus comprises at least two groups of straightening components arranged below the rotating platform. The straightening components are arranged along the directions corresponding to the directions to be connected, and a guide plate is arranged at the bottom of the rotating platform. The straightening components are used to limit the guide plate so that the track on the rotating platform is aligned with the track to be connected.

[0011] By adopting the above technical solution, after the rotating platform rotates, if it does not rotate into place, the straightening component can be contacted with the guide plate to make the side of the guide plate parallel to the track to be connected, so that the track on the rotating platform is aligned with the track to be connected.

[0012] In a specific possible implementation scheme, the righting assembly includes a support frame, a righting column rotatably connected to the support frame, and a driving member that drives the righting column to support the rotating platform.

[0013] By adopting the above technical solution, the support frame is used to provide effective support for the righting column and can make the righting column rotate. The driving member is used to drive the righting column to support and remove the support of the bottom end of the rotating platform. The righting column has two functions. One is to cooperate with the righting plate to align the rotating platform when the rotating platform is not aligned. The other is to support the rotating platform when the shuttle bus leaves the rotating platform to prevent it from tipping over.

[0014] In a specific possible implementation scheme, the middle part of the righting column is rotatably connected to the support frame, and the driving member includes a hydraulic cylinder, one end of the hydraulic cylinder is hinged to the ground, and the other end of the hydraulic cylinder is hinged to the lower part of the righting column.

[0015] By adopting the above technical solution, the middle part of the righting column is rotatably connected to the support frame, which can facilitate rapid and accurate righting under the action of the hydraulic cylinder and timely support the rotating platform.

[0016] In a specific possible implementation manner, a chamfer is provided on a side of the bottom end of the righting column close to the hydraulic cylinder, and a chamfer is provided on a side of the top end of the righting column away from the hydraulic cylinder.

[0017] By adopting the above technical solution, the setting of the two chamfers can prevent the righting column from colliding with the bottom end of the rotary platform under the drive of the hydraulic cylinder, and quickly complete effective support.

[0018] In a specific feasible implementation scheme, a through groove is opened in the middle of the upper end of the righting column, and the opening direction of the through groove is parallel to the track on the rotating platform. Balls are provided on two opposite side walls of the through groove, and the distance between the two balls is adapted to the thickness of the guide plate.

[0019] By adopting the above technical solution, the setting of the through groove and the two balls in the through groove can guide the guide plate into the through groove. When the guide plate enters the through groove, the rotating platform is driven by the guide plate to align with the track to be connected. The setting of the balls can reduce the friction between the guide plate and the side of the through groove, making it easier for the guide plate to enter the through groove.

[0020] In a specific possible implementation manner, one end of the guide plate close to the righting column is arc-shaped.

[0021] By adopting the above technical solution, one end of the guide plate close to the straightening column is arc-shaped and can easily enter the through groove to help the rotary platform return to its original position.

[0022] In a specific feasible implementation scheme, the rotating platform includes a column and a turntable rotatably connected to the upper end of the column, a coaxial gear ring is arranged on the column, a drive motor is arranged at the bottom end of the turntable, a gear meshingly connected to the gear ring is arranged on the output shaft of the drive motor, and a guide plate is arranged at the bottom end of the turntable.

[0023] By adopting the above technical solution, the drive motor is configured to drive the turntable to rotate, and stops working after the turntable rotates to the right position, giving the guide plate space to return to its original position.

[0024] The present application includes at least one of the following beneficial technical effects:

[0025] 1. The present application uses a straightening assembly and a guide plate installed under the turntable to correct a turntable that has not rotated into place, so that the turntable can be in place after rotation, which is convenient for the shuttle bus to enter and leave. The setting of the straightening column can play a supporting role while guiding, avoiding damage to the turntable when the shuttle bus enters or leaves the turntable, and effectively solves the problem of misalignment between the turntable after rotation and the track to be connected.

[0026] 2. The end of the guide plate close to the straightening column is arc-shaped, which can easily enter the through groove and avoid hard contact.

[0027] 3. The upper and lower ends of the righting column are both chamfered to facilitate the conversion of the righting column between the inclined and vertical states. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] Example 1

[0036] The present application embodiment discloses a rotary platform positioning device for a shuttle bus, referring to Figure 1-Figure 4 , including at least two groups of righting assemblies installed under the rotating platform, the righting assemblies are installed under the rotating platform along the directions corresponding to the directions to be connected, for example, if there are two directions to be connected, the number of righting assemblies is two and corresponds to the two directions respectively, and a guide plate 1 is fixedly connected to the bottom end of the rotating platform; in this embodiment, there are two directions to be connected, and the number of righting assemblies is two;

[0037] The number of the guide plates 1 can be one or two. When the number of the guide plates 1 is one, the guide plate 1 is located between the two tracks on the turntable 9, and the length direction of the guide plate 1 is parallel to the tracks; when the number of the guide plates 1 is two, the two guide plates 1 are respectively located below the two tracks on the turntable 9; in this embodiment, taking one guide plate 1 as an example, the end of the guide plate 1 close to the straightening column 3 is arranged in an arc shape, which can facilitate entry into the through groove 6 to avoid hard contact;

[0038] The straightening assembly is used to limit the position of the guide plate 1 so that the track on the rotary platform is aligned with the track to be connected.

[0039] Specifically, the rotary platform includes a column 8 and a turntable 9 rotatably connected to the upper end of the column 8 through a bearing, a coaxial gear ring 11 is fixedly connected to the column 8, a drive motor 10 is installed at the bottom end of the turntable 9, two parallel tracks are installed at the upper end of the turntable 9, a gear 12 meshing with the gear ring 11 is installed on the output shaft of the drive motor 10, and a guide plate 1 is fixedly installed (welded) at the bottom end of the turntable 9;

[0040] Specifically, the righting assembly includes a support frame 2, a righting column 3 rotatably connected to the support frame 2, and a driving member 4 that drives the righting column 3 to support the turntable 9 in the rotating platform. The middle part of the righting column 3 is rotatably connected to the support frame 2. The driving member 4 includes a hydraulic cylinder, one end of the hydraulic cylinder is hinged to the ground, and the other end of the hydraulic cylinder is hinged to the lower part of the righting column 3. The crooked righting column 3 is changed to vertical through the operation of the hydraulic cylinder. After the righting column 3 is vertical, it just stands between the turntable 9 and the ground, providing support for the turntable 9, so as to facilitate the shuttle bus to leave the turntable 9;

[0041] In this embodiment, in order to facilitate the uprighting column 3 to change from tilted outward to vertical, or from vertical to tilted, a chamfer 5 is provided on the side of the bottom end of the uprighting column 3 close to the hydraulic cylinder, and a chamfer 5 is provided on the side of the upper end of the uprighting column 3 away from the hydraulic cylinder. The chamfer 5 on the uprighting column 3 facilitates the rotation of the uprighting column 3.

[0042] In this embodiment, a through groove 6 is provided in the middle part of the upper end of the straightening column 3, and the opening direction of the through groove 6 is parallel to the track on the rotating platform. Balls 7 are installed on the two opposite side walls in the through groove 6, and the distance between the two balls 7 is adapted to the thickness of the guide plate 1. When the inclined straightening column 3 is pulled vertically by the hydraulic cylinder, the guide plate 1 will gradually enter the through groove 6 and gradually enter between the two balls 7 under the action of the balls 7; if the turntable 9 is not rotated into place, the track on the turntable 9 and the track to be connected are not aligned, and when the guide plate 1 enters between the two balls 7, it will gradually drive the turntable 9 to rotate so that the tracks are aligned; if the turntable 9 is rotated into place, the guide plate 1 will also gradually enter the through groove 6 and gradually enter between the two balls 7 under the action of the balls 7, but the turntable 9 will not rotate; after the straightening column 3 is vertical, the bottom end of the turntable 9 will be supported, and at the same time, the setting of the through groove 6 can prevent the turntable 9 from rotating during the movement of the shuttle bus.

[0043] Working principle: In the initial state, the track on the turntable 9 is aligned with the track that needs to be connected in one direction. At this time, the righting column 3 in this direction is in a vertical state, and the righting column 3 in the other direction is in an inclined state. The righting column 3 is located between the ground and the turntable 9 to abut the turntable 9, and the guide plate 1 is located in the through groove 6 on the righting column 3. When the shuttle bus moves to the track on the turntable 9, the hydraulic cylinder operates the righting column 3 in the vertical state to become inclined, and the drive motor 10 drives the gear 12 to move around the ring gear 11, and the turntable 9 moves accordingly. When the track on the turntable 9 rotates toward the track in the other direction, the hydraulic cylinder works to drive the righting column 3 corresponding to the other direction to become a vertical state. After the righting column 3 becomes a vertical state, the guide plate 1 is located in the groove on the righting column 3, and the track on the turntable 9 is aligned with the track in the other direction, and the ferry bus leaves the turntable 9.

[0044] In combination with the above, the present application corrects a rotating platform that has not rotated into place through a straightening assembly and a guide plate 1 installed under the rotating platform, so that the rotating platform is in place after rotation, which is convenient for the entry and exit of the shuttle bus. The setting of the straightening column 3 can play a supporting role while guiding, avoiding damage to the rotating platform when the shuttle bus enters or leaves the rotating platform, and effectively solving the problem of misalignment between the rotating platform and the track that needs to be connected after rotation.

[0045] Example 2

[0046] The present application embodiment requests to disclose a rotary platform positioning device for a ferry vehicle, referring to Figure 5 Compared with Example 1, the difference is that: in this embodiment, a groove is provided on the end of the guide plate 1 facing the direction to be connected, and a protrusion adapted to the groove is provided on the side of the upper end of the straightening column 3 close to the guide plate 1, and symmetrical balls 7 are provided on both sides of the protrusion. When the protrusion is located in the groove, the ball 7 contacts with the groove.

[0047] The implementation principle of Example 2 is as follows: in the initial state, the track on the turntable 9 is aligned with the track that needs to be connected in one direction. At this time, the righting column 3 in this direction is in a vertical state, and the righting column 3 in the other direction is in an inclined state. The righting column 3 is located between the ground and the turntable 9 to abut the turntable 9, and the protrusion on the righting column 3 is located in the groove of the guide plate 1. When the shuttle bus moves to the track on the turntable 9, the hydraulic cylinder operates the righting column 3 in the vertical state to become inclined, and the drive motor 10 drives the gear 12 to move around the ring gear 11, and the turntable 9 moves accordingly. When the track on the turntable 9 rotates toward the track in the other direction, the hydraulic cylinder works to drive the righting column 3 corresponding to the other direction to become a vertical state. After the righting column 3 becomes a vertical state, the protrusion on the righting column 3 is located in the groove on the guide plate 1, and the track on the turntable 9 is aligned with the track in the other direction, and the shuttle bus leaves the turntable 9.

[0048] Example 3

[0049] The present application embodiment requests to disclose a rotary platform positioning device for a ferry vehicle, referring to Figure 1 and Figure 2 Compared with Example 1, the difference is that: in order to make the operation of the rotating platform more stable, four abutment columns 13 are arranged under the turntable 9, and the four abutment columns 13 are evenly distributed around the column 8 as the axis. Balls 7 are installed on the upper ends of the four abutment columns 13. The abutment columns 13 are used to provide support for the turntable 9 during the rotation process, thereby increasing the stability of the rotating platform.

[0050] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
