[0043] The specific implementation method is as follows: the moving unit is the carrying unit 3, the front plate 31 and the rear plate 32 are respectively set on the top of the track body 11, and the front plate 31 and the rear plate 32 are rotatably connected by the guide shaft 33, which enables the carrying unit 3 to turn a certain way along the surface of the track body 11, thereby adapting to different driving needs.

[0044] The front panel 31 and the rear panel 32 are made of high-strength, lightweight materials, such as aluminum alloy or carbon fiber, to ensure sufficient strength and rigidity while reducing weight.

[0045] The guide shaft 33 connects the front plate 31 and the rear plate 32. The guide shaft 33 allows the front plate 31 and the rear plate 32 to rotate relative to each other within a certain range, enabling the front plate 31 and the rear plate 32 to rotate and giving the bearing unit 3 steering capability.

[0046] The guide shaft 33 is made of precision-machined cylindrical stainless steel to ensure smooth and accurate rotation.

[0047] The support ring 34 and the optical shaft 36 are used to support and rotate the support wheel 35. The support ring 34 is fixedly installed at the bottom of the rear plate 32, and the optical shaft 36 provides support for the support wheel 35.

[0052] The front longitudinal shaft 37 and the rear longitudinal shaft 38 are fixedly mounted on the front plate 31 and the rear plate 32, respectively, and they are connected to the front limit wheel 39 and the rear limit wheel 310. The front limit wheel 39 and the rear limit wheel 310 cooperate with the limiting groove 13 of the track body 11 to further restrict the movement path of the bearing unit 3 and ensure the stability of the bearing unit 3 moving on the track body 11.

[0053] The front longitudinal axis 37 and the rear longitudinal axis 38 are cylindrical, and the side sections of the front limiting wheel 39 and the rear limiting wheel 310 are inclined to adapt to the contour and guide of the limiting groove 13.

[0054] The guide rod 313, the support shaft 312, and the guide wheel 311 together form a guiding system to provide additional stability and guiding force before the front plate 31 and the rear plate 32 turn. The guide rod 313 is fixedly installed at the bottom end of the guide shaft 33, and the support shaft 312 is rotatably connected to the guide wheel 311. The guide wheel 311 can roll inside the limiting groove 13 of the track body 11 to guide the turning movement of the front plate 31 and the rear plate 32.

[0055] The guide rod 313, support shaft 312 and guide wheel 311 are made of high-strength, wear-resistant stainless steel to ensure stability and durability during steering.

[0056] It also includes a clamping unit 4, which includes a gear 46. The gear 46 is fixedly installed on the outside of the guide shaft 33. An angle sensor 44 is fixedly installed on the bottom of the front plate 31. The angle sensor 44 is also located on one side of the gear 46. Locking units are symmetrically arranged on the outside of the gear 46. The two locking units are respectively located at the bottom of the front plate 31 and the rear plate 32. A bidirectional translation drive 45 is arranged between the two locking units. The bidirectional translation drive 45 is used to drive the locking units to lock.

[0057] The locking unit includes a first limiting plate 41, which is fixedly installed at the bottom of the rear plate 32. A first friction plate 42 is provided on the side of the first limiting plate 41 near the gear 46. A first fixed shaft 43 is rotatably installed on one side of the first friction plate 42 and is fixedly connected to the rear plate 32. A second limiting plate 411 is fixedly installed at the bottom of the front plate 31. The second limiting plate 411 is symmetrically arranged with the first limiting plate 41.

The side of the first friction plate 42 and the second friction plate 421 away from the angle sensor 44 is rotatably connected to the output end of the bidirectional translation drive 45.

[0058] The specific implementation is as follows: When the clamping unit 4 is working normally, it locks the relative positions of the front plate 31 and the rear plate 32 to prevent them from rotating accidentally when they do not need to turn. When they need to turn, the clamping unit 4 unlocks the front plate 31 and the rear plate 32, allowing them to rotate freely relative to the guide shaft 33.

[0059] Gear 46 is fixedly installed on the outside of guide shaft 33. The teeth of gear 46 cooperate with angle sensor 44 to detect the rotation angle of guide shaft 33. Angle sensor 44 is a magnetic angle sensor. Bidirectional translation drive 45 includes, but is not limited to, bidirectional electric telescopic rod. It is electrically connected to an external power supply and controlled by an external PLC programming program. Bidirectional translation drive 45 is used to drive the locking unit to lock or unlock, thereby fixing or releasing front plate 31 and rear plate 32.

[0060] The locking unit includes a first limiting plate 41, a first friction plate 42, a first fixed shaft 43, a second limiting plate 411, a second friction plate 421, and a second fixed shaft 431. When the bidirectional translation drive 45 is working, it pushes the first friction plate 42 and the second friction plate 421 to contact the first limiting plate 41 and the second limiting plate 411, generating frictional force, thereby locking the front plate 31 and the rear plate 32. The angle of the gear 46 is adjusted by the angle sensor 44 to retract, so that the first friction plate 42 and the second friction plate 421 are separated from the first limiting plate 41 and the second limiting plate 411, allowing the front plate 31 and the rear plate 32 to rotate relative to each other, thereby turning.

[0061] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
