[0023] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Embodiment 1

[0025] See also Figures 1 to 3 A large rotating device comprises a bracket 1, a rotating mechanism 2, an axial limiting mechanism 3 and a radial limiting mechanism 4, wherein the rotating mechanism 2 can be rotatably arranged on the bracket 1. The bracket 1 is used to support the entire rotating device and serve as a fixed part of the rotating device. The axial limiting mechanism 3 is used to limit the axial position of the rotating mechanism 2 when it rotates on the bracket 1 to prevent the rotating mechanism 2 from moving axially. The radial limiting mechanism 4 is used to limit the radial position of the rotating mechanism 2 when it rotates on the bracket 1 to prevent the rotating mechanism 2 from moving radially. The axial limiting mechanism 3 and the radial limiting mechanism 4 ensure that the rotating mechanism 2 can only perform rotational motion on the bracket 1, and is more stable when rotating. The bracket 1 can adopt a hollow box structure or a frame structure. The rotating mechanism 2 is arranged inside the bracket 1, and the axial ends pass through the bracket 1. The rotating mechanism 2 can be made according to needs, and can be made into a structure with multiple connecting plates in the middle and cylindrical at both ends, and functional components can be accommodated between the connecting plates in the middle.

[0026] See also Figure 2The axial limiting mechanism 3 includes a first roller 31 and a second roller 32. The first roller 31 and the second roller 32 are both arranged on the bracket 1, and can be arranged on the inner side or the outer side of the bracket 1. In this embodiment, the first roller 31 and the second roller 32 are arranged on the inner side of the bracket 1. The rotating shafts of the first roller 31 and the second roller 32 are perpendicular to the rotating shaft of the rotating mechanism 2. For example, when the rotating shaft of the rotating mechanism 2 is in a vertical direction, the rotating shafts of the first roller 31 and the second roller 32 are in a horizontal direction. The first roller 31 and the second roller 32 can both be arranged in the form of a small bearing outside the rotating shaft. An annular limiting plate 35 is arranged on the periphery of the rotating mechanism 2, and the annular limiting plate 35 is perpendicular to the rotating shaft of the rotating mechanism 2. When the bracket 1 is installed with the rotating mechanism, the first roller 31 and the second roller 32 form a roller group, and the annular limit plate 35 is clamped between the first roller 31 and the second roller 32, so that when the rotating mechanism 2 rotates, the annular limit plate 35 is clamped by the first roller 31 and the second roller 32 on both sides, ensuring that the rotating mechanism 2 can rotate while making the rotating mechanism 2 axially immovable when rotating, thereby ensuring the axial stability during rotation.

[0027] See also Figure 2 , a circular surface 43 is arranged on the periphery of the rotating mechanism 2, generally a partial cylindrical surface is arranged, and it can be arranged at both ends. The radial limiting mechanism 4 includes a plurality of third rollers 41, generally at least three are arranged, and the third rollers 41 can also be in the form of bearings arranged outside the rotating shaft. Each of the third rollers 41 is arranged on the bracket 1 close to the circular surface 43, and the rotating axis of the third roller 41 is parallel to the rotating axis of the rotating mechanism 2. Therefore, the three rollers 41 can clamp the rotating mechanism 2 from the periphery of the circular surface 43, and the circular surface 43 and the three rollers 41 can be rotated, thereby limiting the radial movement of the rotating mechanism 2 and ensuring the radial stability of the rotating mechanism 2 when the rotating mechanism 2 rotates. The aforementioned axial limiting mechanism 3 and radial limiting mechanism 4 use multiple rollers to connect the bracket 1 and the rotating mechanism 2, and the parts are easy to obtain, and the installation and maintenance are convenient and flexible.

[0028] See also Figure 1 and 3 , the axial sides of the rotating mechanism 2 on the bracket 1 are provided with axial limiting mechanisms 3 and radial limiting mechanisms 4. For example, when the rotating device is vertically arranged, the rotating mechanism 2 rotates in the horizontal plane, and the axial sides of the rotating mechanism 2 are the upper and lower sides. At this time, the axial limiting mechanisms 3 and radial limiting mechanisms 4 are provided on the upper and lower sides of the outside or inside of the bracket 1. The axial limiting mechanisms 3 and radial limiting mechanisms 4 are provided on both sides of the bracket 1. When the rotating mechanism 2 rotates, the axial limiting mechanisms 3 and radial limiting mechanisms 4 have a better limiting effect on the rotating mechanism 2, and the rotating mechanism 2 is more stable when rotating.

[0029] See also Figure 2, the axial limiting mechanism 3 can adopt the following specific structure: the first roller 31 is arranged on the first roller seat 33, and the second roller 32 is arranged on the second roller seat 34. The first roller seat 33 and the second roller seat 34 are both arranged on the bracket 1, and the positions of the first roller seat 33 and the second roller seat 34 are adjustable in the direction parallel to the axial direction of the rotating mechanism 2. For example, a mounting block can be arranged on the lower side of the bracket 1, and the first roller seat 33 and the second roller seat 34 are sequentially arranged on the mounting block up and down through the slide rail mechanism in the up and down directions. The first roller seat 33 and the second roller seat 34 are also connected to the mounting block by screws, and the height of the first roller seat 33 and the second roller seat 34 is adjusted by screwing. The use of an adjustable axial limiting mechanism 3 is convenient for moving the equipment, and the rotating mechanism 2 can be clamped axially by adjustment when it is worn for a long time to make it axially stable. It can also be used to replace different rotating mechanisms 2. At least two sets of first rollers 31 and second rollers 32 are arranged on each axial side of the rotating mechanism 2. For example, two sets of first rollers 31 and second rollers 32 can be arranged on the upper and lower sides of the bracket 1 according to the position shown in the figure, which can better limit the rotating mechanism 2 and ensure its axial stability during rotation.

[0030] See also Figure 1 and Figure 3 In this embodiment, three groups of third rollers 41 are arranged on each axial side of the rotating mechanism 2 on the bracket 1, and each of the third rollers 41 is arranged on each third roller seat 42, and each of the third roller seats 42 is arranged on the bracket 1. At least one of the three groups of third roller seats 42 is adjustable in the radial direction of the rotating mechanism 2. The third roller seat 42 can also be adjusted in the manner of the first roller seat 33 and the second roller seat 34. Providing one or more groups of adjustable third roller seats 42, that is, the third roller 41 is adjustable, can facilitate the movement of the equipment, adjust the equipment when it is worn over time, and can also make the same bracket 1 match the rotating mechanism 2 of different diameters.

[0031] The large rotating device of this embodiment is used for large equipment, and other functional components can be installed inside and at both ends of the rotating mechanism 2. A gear structure can be arranged on the periphery of the rotating mechanism 2, and a small gear driven by a motor is arranged on the bracket 1 to mesh with the gear arranged on the periphery of the rotating mechanism 2, so as to drive the rotating mechanism 2 to rotate on the bracket 1. During the rotation, the axial limiting mechanism 3 and the radial limiting mechanism 4 provide axial and radial limiting respectively to ensure that the rotating mechanism 2 can only rotate.

[0032] Embodiment 2

[0033] See also Figures 1 to 4 Based on the first embodiment, the rotating device in this embodiment further includes a supporting mechanism 5, which is used to support the rotating device and can adjust the three-dimensional position of the bracket 1 to facilitate the alignment of the rotating device when it cooperates with other equipment.

[0034] See also Figures 1 to 4 The support mechanism 5 includes a support 51, the bracket 1 is arranged on the support 51, and the position of the bracket 1 on the support 51 is adjustable. In addition, a separate mounting plate can be provided, the mounting plate is adjustably arranged on the support 51, and the bracket 1 is fixedly arranged on the mounting plate. The bracket 1 is movably arranged on the support 51, and the position of the bracket 1 on the support 51 can be adjusted by a first adjustment mechanism 53 and a second adjustment mechanism 54.

[0035] See also Figure 4 The support mechanism 5 also includes a plurality of first adjustment mechanisms 53, which are generally arranged in a circle outside the support mechanism 5. Each of the first adjustment mechanisms 53 includes a first screw 531 and a second screw 532. The first screw 531 passes through the bracket 1 and is screwed on the support 51, that is, the first screw 531 is movable but not connected to the bracket 1, and is connected to the support 51 through a threaded structure. The first screw 531 can be a screw with a nut. The second screw 532 abuts against the support 51 and is screwed on the bracket 1, that is, it is only supported on the support 51 but not connected, and is connected to the bracket 1 through a threaded structure. In this way, the distance between the bracket 1 and the support 51 can be adjusted by rotating the second screw 532, which plays a role in adjusting the bracket 1 in one dimension. After adjusting the bracket 1 to a suitable position, locking the first screw 531 can fix the position of the bracket 1.

[0036] See also Figure 4 , the first screw 531 and the second screw 532 can be arranged adjacently and spaced apart, but it is better to adopt a coaxial arrangement to avoid the bracket 1 from easily shifting when adjusting relative to the support 51. This embodiment adopts a coaxial arrangement, specifically: the second screw 532 adopts a hollow screw, the length of the first screw 531 is longer than the second screw 532, and the first screw 531 passes through the second screw 532. In addition, a fixing nut 533 is provided on the second screw 532, and the fixing nut can be rotated on the second screw 532 to a position abutting against the bracket 1, so as to fix the bracket 1 and the second screw 532. It is better to set the fixing nut 533 on the outside of the bracket 1, so as to facilitate adjustment. After the second screw 532 is rotated to adjust the bracket 1 to a suitable position, the fixing nut 533 is rotated to abut against the bracket 1, which can play a role in making the bracket 1 more stable when fixed.

[0037] See also Figure 1 and 3, and further includes a second adjustment mechanism 54, the second adjustment mechanism 54 includes a third screw 541, the third screw 541 is screwed on the support 51, and presses against the surroundings of the bracket 1. Specifically, a mounting block relative to the surroundings of the bracket 1 can be arranged around the support 51, and the third screw 541 is screwed on the mounting block, and one end abuts against the surroundings of the bracket 1. In addition, the inner wall diameter of the second screw 532 is larger than the outer diameter of the first screw 531, that is, the first screw 531 has a movable space in the second screw 532, and the first screw 531 is connected to the support 51, and the second screw 532 is connected to the bracket 1, so there is a relative movement space between the support 51 and the bracket 1, and the position of the bracket 1 on the support 51 can be adjusted by the third screw 541.

[0038] When the rotating device of this embodiment needs to be aligned with other equipment when assembled together, the first screw 531 and the fixing nut 533 can be loosened first, and the position of the bracket 1 on the support 51 can be adjusted by the third screw 541, including adjustment in two dimensions; after adjustment, the second screw 532 is adjusted to adjust the distance between the bracket 1 and the support 51, thereby realizing adjustment in the third dimension. After adjustment, the first screw 531 and the fixing nut 533 can be tightened.

[0039] In both the first and second embodiments, the annular stop plate 35 and the circular surface 43 are arranged on the rotating mechanism 2, and the roller set and the third roller 41 are arranged on the bracket 1. Alternatively, the annular stop plate 35 and the circular surface 43 are arranged on the bracket 1, and the roller set and the third roller 41 are arranged on the rotating mechanism 2, and other auxiliary mechanisms can be changed accordingly. In the first and second embodiments, each roller is arranged on a fixed bracket, which is more conducive to the stability of the rotating mechanism 2 during rotation.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
