[0002] The lifting platform is a widely used lifting mechanism. It plays an important role in the current automated production lines, warehousing and logistics, construction, aerospace and other industries. The lifting platform converts the rotary motion of the drive motor into the vertical lifting motion of the platform through transmission.

[0003] At present, mechanical transmission lifting platforms are mainly based on worm gear transmission and servo electric cylinder. During the transmission process of the worm gear, there is serious friction between the tooth surfaces and severe heat generation, which leads to a shortened life of the worm gear and reduced transmission efficiency. In addition, the worm gear needs to be made of expensive wear-resistant materials, which increases the manufacturing cost. At the same time, due to the limitation of slip speed during worm gear transmission, the worm gear speed is difficult to increase, so the vertical movement speed of the lifting platform is low.

[0004] The servo electric cylinder lifting platform uses multiple servo electric cylinders to lift the lifting platform. Since the components of the servo electric cylinder are relatively expensive, the overall manufacturing cost of the lifting platform is high; the control system of the servo electric cylinder is relatively complex and requires a special controller and programming to achieve closed-loop control, which increases the complexity and cost of the system; due to the characteristics of the servo system, it has high requirements for environmental conditions, such as temperature, humidity and other factors, which will have a serious impact on the stability of the system during use.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0029] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] The lifting platform is a widely used lifting mechanism. It plays an important role in the current automated production lines, warehousing and logistics, construction, aerospace and other industries. The lifting platform converts the rotary motion of the drive motor into the vertical lifting motion of the platform through transmission.

[0032] At present, mechanical transmission lifting platforms are mainly based on worm gear transmission and servo electric cylinder. During the transmission process of the worm gear, there is serious friction between the tooth surfaces and severe heat generation, which leads to a shortened life of the worm gear and reduced transmission efficiency. In addition, the worm gear needs to be made of expensive wear-resistant materials, which increases the manufacturing cost. At the same time, due to the limitation of slip speed during worm gear transmission, the worm gear speed is difficult to increase, so the vertical movement speed of the lifting platform is low.

[0033] The servo electric cylinder lifting platform uses multiple servo electric cylinders to lift the lifting platform. Since the components of the servo electric cylinder are relatively expensive, the overall manufacturing cost of the lifting platform is high; the control system of the servo electric cylinder is relatively complex and requires a special controller and programming to achieve closed-loop control, which increases the complexity and cost of the system; due to the characteristics of the servo system, it has high requirements for environmental conditions, such as temperature, humidity and other factors, which will have a serious impact on the stability of the system during use.

[0034] In order to solve the above technical defects, the inventor provides a lifting mechanism and a working platform based on face gear transmission.

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figure 1-Figure 5 As shown, in the first aspect, an embodiment of the present invention provides a lifting mechanism based on face gear transmission, including a base plate 4, on which a support frame 5 and a longitudinal lifting device are provided; a driving device 8 and a face gear shaft system 10 are installed on the support frame 5, and the driving device 8 is connected to the longitudinal lifting device through the face gear shaft system 10; wherein the driving device 8 and the face gear shaft system 10 are axially perpendicular; and the face gear shaft system 10 and the longitudinal lifting device are axially parallel; when used, the driving device 8 is preferably a motor, and under the drive of the driving device 8, the face gear shaft system 10 drives the longitudinal lifting device to move, thereby realizing the function of up and down lifting. During the entire lifting process, by adopting the face gear shaft system 10, the mechanism realizes efficient transmission between the driving device 8 and the longitudinal lifting device. Since the face gear 101 transmission has the characteristics of large transmission ratio, strong load-bearing capacity and compact structure, the mechanism can still maintain a small volume and weight when transmitting a large torque. Secondly, the use of the face gear shaft system 10 to drive the longitudinal lifting device to lift and lower not only improves the moving speed of the upper platform 1, but also reduces the manufacturing cost and improves the stability of lifting and lowering. As shown in FIG. Figure 2 As shown, the support frame 5 is arranged in the middle of the bottom plate 4, and the longitudinal lifting device is arranged around the bottom plate 4; wherein, the longitudinal lifting device includes a lifting assembly and a transmission assembly, and the face gear shaft system 10 is rotatably connected to the top of the support frame 5; one end of the transmission assembly is connected to the face gear shaft system 10, and the other end is connected to the lifting assembly. In this structure, the support frame 5 is located in the middle of the bottom plate 4, providing a stable support point for the entire mechanism, which helps to disperse and withstand various forces and vibrations during the operation of the mechanism, and improve the stability and rigidity of the overall structure. The longitudinal lifting device is distributed around the bottom plate 4, which helps to balance the torque during the lifting process, reduce the deformation and vibration caused by the eccentric load, and further improve the stability of the mechanism. The face gear shaft system 10 is rotatably connected to the top of the support frame 5, so that the driving force of the driving device 8 can be transmitted to the lifting assembly more directly and efficiently, reducing the energy loss and friction loss in the transmission process; at the same time, the transmission assembly, as a key component connecting the face gear shaft system 10 and the lifting assembly, optimizes the transmission path, ensures the smooth transmission of force, and improves the transmission efficiency and response speed. Finally, the layout of the support frame 5 and the longitudinal lifting device fully utilizes the space of the base plate 4, which not only avoids space waste, enables the mechanism to perform its maximum function within a limited space, but also facilitates maintenance and overhaul of the mechanism.

[0036] Further, the lifting assembly includes a guide member 3 and a sliding member, the guide member 3 is vertically installed on the top of the bottom plate 4, the sliding member is slidably connected to the outside of the guide member 3, and a rack 2 is provided on the outside of the sliding member; the transmission assembly includes a transmission shaft 6, the transmission shaft 6 is rotatably connected to the top of the support frame 5, and one end of the transmission shaft 6 close to the face gear shaft system 10 is provided with a second cylindrical gear 11, and the second cylindrical gear 11 is meshed and connected with the face gear shaft system 10; A third cylindrical gear 12 is provided at one end of the transmission shaft 6 close to the sliding member, and the third cylindrical gear 12 is meshed with the rack 2. The guide member 3 is vertically installed on the top of the base plate 4, providing a stable guide for the sliding member, ensuring the straightness and accuracy during the lifting process. At the same time, the sliding connection between the sliding member and the guide member 3, and the meshing connection between the third cylindrical gear 12 and the rack 2, together constitute a precise transmission chain, so that the lifting movement can be carried out according to a predetermined trajectory and speed, and accurate lifting control is achieved. In addition, the meshing connection between the second cylindrical gear 11 and the face gear shaft system 10 can convert the rotational movement of the drive device 8 into the rotational movement of the transmission shaft 6, thereby achieving effective power transmission; the meshing connection between the third cylindrical gear 12 and the rack 2 converts the rotational movement of the transmission shaft 6 into the linear lifting movement of the sliding member. This conversion method is simple, direct and efficient. Furthermore, the transmission shaft 6 is rotatably connected to the top of the support frame 5, and is meshed with the face gear shaft system 10 and the rack 2 through cylindrical gears, respectively, so that the entire transmission system has a compact structure and a reasonable layout; during use, by adjusting the length of the rack 2 and the position of the transmission shaft 6, the lifting stroke and lifting speed can be easily changed to meet the needs of different application scenarios. In addition, the lifting mechanism also has good scalability and can be easily integrated with other mechanical systems or control systems.

[0037] like Figure 1 As shown, the longitudinal lifting device also includes an upper platform 1, which is installed on the top of the lifting assembly. The upper platform 1 provides a stable bearing surface for the lifting mechanism, on which various objects or equipment that need to be lifted can be placed or fixed, so that the application scope of the lifting mechanism has been greatly expanded, and it can meet the lifting needs in different fields and scenarios. At the same time, the close connection between the upper platform 1 and the lifting assembly ensures the stability and safety of the object during the lifting process. Even at high altitudes or in complex environments, the object can be lifted and lowered smoothly, avoiding safety hazards caused by shaking or deviation. Through the upper platform 1, whether in industrial production, construction, logistics and transportation or other fields, the lifting operation of the object can be realized by installing the upper platform 1, meeting diverse needs.

[0038] like Figure 2As shown, the sliding member is a sliding column. The columnar structure of the sliding column has high rigidity and stability, and can withstand large loads without being easily deformed or damaged, thereby ensuring the stability and safety of the object during the lifting process and improving the carrying capacity of the lifting mechanism. At the same time, the sliding column and the guide member 3 are slidably connected to reduce friction and wear, improve the smoothness and accuracy of the lifting, help reduce energy loss and noise, and enhance the overall performance of the lifting mechanism.

[0039] like Figure 2-Figure 5 As shown, two groups of bases are symmetrically arranged on the outer side of the support frame 5, and the number of bases in each group is two. A first bearing seat 7 is arranged on the top of the base, and the transmission shaft 6 is rotatably connected to the first bearing seat 7; in this structure, the two groups of symmetrically arranged bases provide stable support for the transmission shaft 6, ensure the stability and rigidity of the transmission shaft 6 during operation, help to disperse and withstand the force and vibration generated by the transmission shaft 6, and improve the stability and supporting force of the entire longitudinal lifting device; and the transmission shaft 6 is rotatably connected to the first bearing seat 7, which reduces friction and wear during transmission and improves the smoothness and efficiency of transmission. The symmetrically arranged base and the first bearing seat 7 make the installation and disassembly of the transmission shaft 6 more convenient. When the transmission shaft 6 needs to be repaired or replaced, the relevant components can be easily disassembled, reducing the difficulty and cost of maintenance.

[0040] Furthermore, the guide member 3 is a guide column, which is usually made of high-strength, wear-resistant material, has high load-bearing capacity and durability, and can withstand the pressure and friction generated by the sliding member during the lifting process without being easily deformed or damaged, thereby extending the service life of the longitudinal lifting device. In addition, the contact area between the guide column and the sliding member is relatively small, and the contact surface is usually precision-machined and lubricated, so the friction and wear between them are small, which can reduce energy loss and noise, and improve the smoothness and efficiency of lifting. During application, the guide column is an independent component that is easy to install and adjust. During the installation of the lifting device, the position and number of the guide column can be adjusted according to actual needs to meet the guidance requirements in different scenarios; in addition, the disassembly and replacement of the guide column is also relatively convenient, which reduces the difficulty and cost of maintenance.

[0041] like Figure 3As shown, the face gear shaft system 10 includes a face gear 101, a bearing cover 102, a bearing 103 and a second bearing seat 104. The second bearing seat 104 is arranged on the top of the support frame 5, and the bearing 103 is arranged in the second bearing seat 104; the bearing cover 102 is arranged on the second bearing seat 104, and the face gear 101 is arranged in the hole of the bearing 103. The face gear 101 meshes with the second cylindrical gear 11 on the transmission shaft 6 to form a stable transmission relationship; and because the meshing area of ​​the face gear 101 is large and the contact stress is evenly distributed, it can transmit greater torque and improve the transmission efficiency. In the above structure, the setting of the bearing 103 ensures the stability and accuracy of the face gear 101 during operation, and reduces the energy loss and noise caused by vibration and deviation. The second bearing seat 104 provides a solid support for the bearing 103 and the face gear 101, and can withstand large radial and axial loads, thereby enhancing the load-bearing capacity and durability of the entire face gear shaft system 10. The use of the bearing gland 102 further fixes the bearing 103 to prevent it from loosening or displacement during operation, thereby ensuring the stability and reliability of the face gear shaft system 10. In terms of installation, the second bearing seat 104 is directly set on the top of the support frame 5, which simplifies the installation process and reduces the difficulty of installation. In addition, the bearing 103 and the face gear 101 are independent components, which are easy to disassemble and replace, reducing maintenance costs and time. The entire lifting mechanism is controlled by a control system during operation. First, the driving device 8 is controlled to rotate so that the driving device 8 drives the first cylindrical gear 9 to rotate. When the first cylindrical gear 9 rotates, the face gear 101 is driven to rotate. The face gear 101 rotates to drive the second cylindrical gear 11 on the inner side of the four transmission shafts 6 to rotate, and the rotational motion is transferred to the third cylindrical gear 2 12 on the outer side of the transmission shaft 6 through the transmission shaft 6. When the third cylindrical gear 2 12 rotates, it meshes with the rack 2, driving the rack 2 to move vertically up and down, driving the sliding column to move, and finally the sliding column drives the upper platform 1 to move up and down, thereby achieving the purpose of lifting.

[0042] In a second aspect, this embodiment provides a work platform, including a platform body, wherein the platform body adopts the lifting mechanism based on face gear transmission as described above to perform lifting operations.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit its protection scope. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
