Description

Technical Field

[0001] This utility model belongs to the technical field of rotary drive equipment, and in particular relates to a multifunctional hollow rotary lifting platform. Background Technology

[0002] Currently, rotating platforms combined with lifting mechanisms are widely used in industrial production, primarily for material handling, assembly positioning, and workpiece flipping. These devices typically employ hydraulic drives to achieve lifting, such as using scissor lift mechanisms or hydraulic cylinders to adjust the platform height, combined with motor-driven gears and slewing supports to achieve horizontal rotation. Some designs also attempt to integrate wheels or mobile trolleys to enhance flexibility, but overall, they still mainly rely on a combination of a single lifting drive and a rotating mechanism, resulting in limited intelligence and weak multi-degree-of-freedom collaborative control capabilities. This makes it particularly difficult to simultaneously meet the requirements for lifting stability and rotational positioning accuracy, especially in heavy-load or high-precision scenarios.

[0003] Insufficient stability of the lifting structure is a key defect restricting the performance of rotary platforms. The lifting end of the hydraulic lifting mechanism is generally fixedly connected to the middle position of the rotary platform. When there is a deviation in the installation plane of the lifting mechanism, it will directly cause the platform to shake during the lifting process, which will affect the dynamic balance during rotation. In addition, the non-axial force during the lifting process will reduce the bearing life, further aggravating the instability during the lifting stage, making it difficult to maintain accurate positioning after the rotation movement changes height. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional hollow rotary lifting platform, which aims to solve the technical problem that the dynamic balance of the rotating mechanism is affected when it rotates during the lifting process due to the use of a single-point driven lifting structure in the existing lifting rotary platform.

[0011] Optionally, the number of lifting drive sources is four groups, and the four groups of lifting drive sources are evenly distributed at intervals along the edge of the base plate. The main drive source is located between the four groups of lifting drive sources.

[0029] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-4 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0030] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0033] In one embodiment of this utility model, such as Figures 1-4 As shown, a multifunctional hollow rotary lifting platform is provided, including a base 100, a multi-point support lifting mechanism 200, and a rotating mechanism 300. The multi-point support lifting mechanism 200 is disposed on the base 100. The multi-point support lifting mechanism 200 is drivenly connected to the rotating mechanism 300. The plane of the rotation path of the output end of the rotating mechanism 300 is parallel to the movement path of the output end of the multi-point support lifting mechanism 200. The output ends of the multi-point support lifting mechanism 200 are multiple sets, and the multiple sets of output ends of the multi-point support lifting mechanism 200 are evenly spaced around the bottom edge of the rotating mechanism 300.

[0034] By employing an innovative layout where the multi-point support lifting mechanism 200 is evenly distributed around the bottom of the rotating mechanism 300, the core defect of insufficient lifting stability leading to decreased rotational accuracy in existing technologies is effectively solved. Multiple sets of lifting output ends synchronously lift the bottom edge of the rotating mechanism 300, forming a ring-shaped uniform force support, overcoming the platform tilting and shaking problem caused by uneven force distribution in traditional single-point lifting or asymmetrical support. At the same time, the design of the rotation path plane being parallel to the lifting movement path ensures that the rotation driving force always acts on a stable horizontal support surface, maintaining the dynamic balance of the platform during lifting and providing a high-precision positioning basis for the rotation action. Compared with the weak collaborative control caused by the separation of the lifting and rotating mechanisms 300 or the discrete support points in existing technologies, the hollow rotating lifting platform provided by this utility model achieves a simultaneous improvement in lifting stability and rotational accuracy through structural integration and mechanical optimization.

[0035] like Figures 1-4As shown, in another embodiment of this utility model, the rotating mechanism 300 includes a base plate 310, a rotating drive source 320, and a vertical rotating component 330. The base plate 310 is located at the output end of the multi-point support lifting mechanism 200. The rotating drive source 320 is disposed on the base plate 310, and the vertical rotating component 330 is disposed on the base plate 310. The rotating drive source 320 is drivenly connected to the vertical rotating component 330. The base plate 310 is arranged in a horizontal direction, and the multiple output ends of the multi-point support lifting mechanism 200 are fixedly connected to the base plate 310 and are evenly spaced along the circumferential edge of the base plate 310.

[0036] The base plate 310 is synchronously lifted by the multi-point support lifting mechanism 200, always maintaining a horizontal posture; the rotary drive source 320 directly drives the load to rotate through the vertical rotating component 330, and the load gravity is evenly transmitted to each lifting output end through the base plate 310, avoiding the rotary drive force from generating an off-center load torque on the lifting mechanism, thereby eliminating platform swaying caused by torque imbalance and ensuring the independent stability of lifting and rotating actions.

[0037] like Figures 1-4 As shown, in another embodiment of this utility model, the vertical rotation assembly 330 includes a mounting base 331, a rotating gear ring 332, and a connecting ring 333. The mounting base 331 is fixedly disposed on the base plate 310, the rotating gear ring 332 is rotatably connected to the mounting base 331, and the connecting ring 333 is fixedly disposed on the rotating gear ring 332. The connecting ring 333 is used to mount the workpiece to be processed, and the rotation drive source 320 is drivenly connected to the rotating gear ring 332.

[0038] The rotary drive source 320 drives the rotary gear ring 332 to rotate within the mounting base 331, thereby causing the connecting ring 333 and the workpiece to rotate horizontally. The rigid fixation between the mounting base 331 and the base plate 310 ensures that the rotational torque is transmitted entirely by the gear ring, preventing rotational vibration from being transmitted to the lifting mechanism. This solves the problem of inaccurate composite motion caused by the lengthy transmission chain in traditional rotary platforms.

[0039] like Figures 1-4As shown, in another embodiment of this utility model, the mounting base 331 includes a support plate 334 and a mounting plate 335. The mounting plate 335 is vertically mounted on the base plate 310. There are two sets of support plates 334, which are distributed at both ends of the mounting plate 335. One end of each support plate 334 is fixedly connected to the base plate 310, and the other end of each support plate 334 is fixedly connected to the mounting plate 335. The output end of the rotary drive source 320 extends to the mounting plate 335. The rotary gear ring 332 is rotatably connected to the mounting plate 335. The output end of the rotary drive source 320 is provided with a drive gear that meshes with the rotary gear ring 332.

[0040] The support plate 334 forms a triangular support structure on both sides of the mounting plate 335, which significantly enhances the torsional stiffness; the meshing position of the drive gear and the rotating gear ring 332 is close to the mounting plate 335, which shortens the lever arm and suppresses gear meshing vibration, prevents the rotating mechanism 300 from deforming under high load, and ensures the flatness of the rotation trajectory.

[0041] like Figures 1-4 As shown, in another embodiment of the present invention, the rotation drive source 320 and the vertical rotation component 330 are located at the center of the base plate 310.

[0042] The centrally located rotary drive assembly ensures that the rotational torque is symmetrically transmitted to the support points around the base plate 310, eliminating the additional bending moment caused by eccentric drive, ensuring the axial consistency of the rotational motion during lifting, and avoiding slight swaying of the platform due to uneven torque distribution.

[0043] like Figures 1-4 As shown, in another embodiment of this utility model, the multi-point support lifting mechanism 200 includes a main drive source 210, a transmission assembly 220, and a lifting drive source 230. The number of lifting drive sources 230 is multiple, and the multiple sets of lifting drive sources 230 are evenly distributed at the top of the base 100. The output end of the lifting drive source 230 is fixedly connected to the end face of the base plate 310. The main drive source 210 is disposed at the top of the base 100, and the main drive source 210 drives the output end of the lifting drive source 230 to move up and down synchronously through the transmission assembly 220.

[0044] A single main drive source 210 synchronously drives all lifting drive sources 230 through a transmission component 220, forcing multiple lifting output ends to move at the same speed, eliminating support height deviation caused by multi-motor control errors from the power source, and achieving absolute synchronization in the lifting process.

[0045] like Figures 1-4As shown, in another embodiment of this utility model, the number of lifting drive sources 230 is four groups, and the four groups of lifting drive sources 230 are evenly distributed at intervals along the edge of the base plate 310. The main drive source 210 is located between the four groups of lifting drive sources 230. The main drive source 210 is driven and connected to two adjacent groups of lifting drive sources 230 through the transmission assembly 220. The other two adjacent groups of lifting drive sources 230 are synchronously driven and connected through the transmission assembly 220.

[0046] The four sets of lifting drive sources 230 are arranged in a rectangular array, with the main drive source 210 in the center, which is linked to the four corner lifting units through a transmission chain. The short-distance symmetrical transmission design greatly reduces the cumulative transmission error, making the four support points form a rigid plane, and completely solving the platform tilting problem caused by transmission delay in traditional distributed drives.

[0047] In another embodiment of this utility model, the lifting drive source 230 is a worm gear screw jack; the main drive source 210 is a servo motor.

[0048] The worm gear's self-locking characteristic automatically locks the position when lifting stops, while the servo motor provides precise speed control. The combination of these two features satisfies micron-level lifting and positioning requirements while avoiding the slow descent phenomenon caused by oil pressure fluctuations common in hydraulic systems, thus improving static stability. For example, in this embodiment, the lifting drive source 230 is an SWL screw jack.

[0049] like Figures 1-4 As shown, in another embodiment of this utility model, the transmission assembly 220 includes a reversing seat 221 and a coupling 222. The reversing seat 221 is disposed on the base 100. The input end of the reversing seat 221 is connected to the output end of the main drive source 210. The reversing seat 221 is provided with two sets of output ends. The output ends of the reversing seat 221 are respectively driven connected to the corresponding lifting drive source 230 through the coupling 222. The lifting drive source 230 away from the reversing seat 221 is synchronously driven connected to its adjacent lifting drive source 230 through the coupling 222.

[0050] The reversing seat 221 distributes the power from the main drive source 210 to the two side lifts, and then transmits it to the remote lift through the coupling 222. The rigid coupling transmission eliminates the elastic deformation error of the belt / chain, ensures that the four sets of screw lifts move in strict synchronization, and eliminates the support height difference caused by the transmission flexibility.

[0051] like Figures 1-4As shown, in another embodiment of this utility model, the multi-point support lifting mechanism 200 further includes a guide assembly 240. There are two sets of guide assemblies 240, which are distributed at both ends of the main drive source 210. The output end of the guide assembly 240 is fixedly connected to the base plate 310. The guide assembly 240 includes a bushing 241 and a guide shaft 242. The bushing 241 is fixedly mounted on the base 100, and the guide shaft 242 is slidably connected to the bushing 241 and the base 100. The end of the guide shaft 242 is fixedly connected to the base plate 310.

[0052] The guide shaft 242 slides vertically within the bushing 241, constraining the base plate 310 to move only along the axial direction; the symmetrical layout of the dual guide components 240 resists lateral force interference, prevents horizontal displacement of the platform caused by off-center load during lifting, and ensures the spatial position accuracy of the rotation center shaft.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
