[0021] In order to help those skilled in the art better understand the technical solutions of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
[0022] Reference Figure 1 and Figure 2In this embodiment, a rotary support device for a controllable pitch propeller and a shafting device includes a base 1, a support plate 2 and a support roller assembly. The support plate 2 is located between the top surface of the base 1 and the support roller assembly. In this embodiment, two groups of support roller assemblies are provided on the top surface of the support plate 2. Both groups of support roller assemblies are used to place and support the controllable pitch propeller.
[0023] Furthermore, in this embodiment, multiple first adjustment rods 4 are disposed between the base 1 and the support plate 2. One first adjustment rod 4 is disposed at the center of the support plate 2, and the remaining first adjustment rods 4 are disposed along the periphery of the support plate 2. The first adjustment rods 4 in this embodiment are preferably screws. One end of the first adjustment rod 4 is pivotally connected to the top of the base 1, and the other end of the first adjustment rod 4 is pivotally connected to the support plate 2. The first adjustment rods 4 extend through the height of the support plate 2. By rotating the first adjustment rod 4, the height between the support plate 2 and the roller support assembly located on the support plate 2 and the ground can be adjusted, thereby facilitating better contact between the roller support assembly and the adjustable pitch propeller.
[0024] Furthermore, the centers of the two support roller assemblies of this embodiment are both located on the same horizontal line parallel to the length of the controllable pitch propeller shaft. Specifically, each support roller assembly includes two symmetrically arranged roller modules 3, each of which includes a roller support 32, a second adjustment rod 33, and a roller 31, wherein the second adjustment rod 33 is perpendicular to the first adjustment rod 4. During use, the axial direction of the controllable pitch propeller shaft is parallel to the axial direction of each roller 31 and is placed between the two rollers 31 of a support roller assembly; the rollers 31 are made of nylon or copper, and the specific material can be selected according to the different support conditions of the controllable pitch propeller shaft to better protect the propeller shaft and reduce friction between the rollers 31 and the propeller shaft.
[0025] Furthermore, each roller support 32 includes a base plate 321 and vertical plates 322 fixedly disposed at both ends of the top surface of the base plate 321. The two ends of a roller 31 are rotatably connected to the two vertical plates 322. A fixing block 35 is provided on the support plate 2 corresponding to each base plate 321. The fixing block 35 is fixedly disposed on the side of the support plate 2. One end of the second adjustment rod 33 is rotatably connected to the fixing block 35, and the other end of the second adjustment rod 33 is rotatably connected to the base plate 321. The second adjustment rod 33 extends across the width of the base plate 321. In this embodiment, the second adjustment rod 33 is preferably a screw.
[0026] Two slots 21, parallel to the second adjustment rod 33, are defined on both ends of each base plate 321 of the support plate 2. The length of the slots 21 is perpendicular to the axial direction of the roller 31. Furthermore, the lengths of the two slots 21 located on the same side of the two base plates 321 in a support roller assembly overlap, ensuring the height consistency of the two roller modules 3 in a set of support roller assemblies. Furthermore, each slot 21 includes a first slot portion 211 and a second slot portion 212 located above the first slot portion 211. The centers of the first slot portion 211 and the second slot portion 212 are aligned in the same vertical direction, and the width of the first slot portion 211 is greater than the width of the second slot portion 212.
[0027] Each base plate 321 is provided with a limit rod 34 at both ends. Each limit rod 34 includes a base 341 and a rod body 342 located above the base 341. The base 341 and the rod body 342 are fixedly connected. The first groove portion 211 of the chute 21 is used to accommodate the base 341, and the second groove portion 212 of the chute 21 is used to accommodate a portion of the rod body 342. The length of the rod body 342 is greater than the height of the second groove portion 212. The outer diameter of the base 341 is greater than the width of the second groove portion 212 and less than the width of the first groove portion 211. The arrangement of the chute 21 and the limit rod 34 allows the corresponding roller support 32 to be driven by rotating the second adjustment rod 33, driving the limit rod 34 to move within the chute 21, thereby facilitating adjustment of the distance between the two roller modules 3 in a support roller assembly. This allows the slewing support device of the present invention to accommodate controllable pitch propellers with different shaft diameters. The arrangement of the first groove portion 211 , the second groove portion 212 , the base 341 and the rod body 342 can guide the movement of the roller module 3 along the slide groove 21 and ensure that the roller module 3 is stably arranged on the top surface of the support plate 2 without shaking.
[0028] The two groups of supporting roller assemblies in the present invention can be adjusted simultaneously or individually according to the specific structure of the adjustable pitch propeller and the shaft system device to be supported. The distance between the two roller modules 3 in the two groups of supporting roller assemblies can also be adjusted to be the same or different according to the outer diameter of the propeller shaft to be supported, so as to make adaptive adjustments to ensure close contact between the roller 31 and the propeller shaft, thereby playing an effective slewing support role.
[0029] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
