[0002] In the fine sealing chamber of the painting workshop, when applying sealant to the weld seams of parts such as the roof, hood, tailgate, and side panels, workers need to stand at a high position to perform the sealant application. Moreover, the height and width of different vehicle models vary greatly, and even for the same vehicle model, the location of the weld seams to be sealed also varies. Therefore, in order to meet the sealant application needs of different vehicle models with large size differences and to facilitate the sealant application operation for employees, the position where the operator stands needs to have flexible and movable characteristics, that is, a lifting platform that can simultaneously achieve Z-axis lifting and Y-axis translation.

[0003] However, existing technologies generally only provide vertical movement. When workers are working on the lifting platform, they cannot adjust the angle of their working position through the platform. In this case, workers need to turn their bodies to perform the subsequent glue application, which is quite troublesome. Moreover, the lifting platform needs to be manually pushed to move, making the movement of the lifting platform quite laborious. Therefore, the flexibility of existing lifting platforms needs to be improved.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0021] The following reference Figures 1 to 8 This application describes a flexible lifting platform provided according to some embodiments.

[0022] In some embodiments, a flexible lifting platform includes: a platform body 1; a bottom frame 2 disposed below the platform body 1; two sets of first scissor bars 3 and second scissor bars 4 arranged left and right, wherein one end of the first scissor bar 3 is hinged to the lower end of the platform body 1, and one end of the second scissor bar 4 is hinged to the bottom of the bottom frame 2, wherein the first scissor bar 3 and the adjacent second scissor bar 4 are cross-hinged; and two sets of lifting drive components arranged left and right between the platform body 1 and the bottom frame 2, used to adjust the support height of the platform body 1; each lifting drive component includes: a hydraulic cylinder 5 disposed between the first scissor bar 3 and the bottom frame 2. The upper cam 501 is hinged at one end to the power end of the hydraulic cylinder 5, and the other end of the upper cam 501 is hinged to the middle of the front end of the first scissor bar 3; the lower cam 502 is hinged at one end to the bottom of the hydraulic cylinder 5, and the other end of the lower cam 502 is hinged to the lower part of the front end of the second scissor bar 4; the left and right sides of the lower end of the platform body 1 and the left and right sides of the bottom of the bottom of the bottom frame 2 are all fixed with first guide rails 6, the other end of the first scissor bar 3 is hinged to an upper guide block 301, and the other end of the second scissor bar 4 is hinged to a lower guide block 401, and the upper guide block 301 and the lower guide block 401 are both slidably connected to the adjacent first guide rails 6.

[0023] In this embodiment, the lifting drive is accomplished by two sets of hydraulic cylinders 5. When the hydraulic cylinders extend, they push the corresponding first scissor bar 3 and second scissor bar 4 through the upper cam 501 and lower cam 502, causing the scissor mechanism to extend. At the same time, the upper guide block 301 and lower guide block 401 slide along the corresponding first guide rod 6, and the platform body 1 rises. Conversely, when the hydraulic cylinders 5 retract, the scissor mechanism retracts, that is, the first scissor bar 3 and the second scissor bar 4 retract in a cross manner, and the platform body 1 descends. In summary, this driving method provides direct force transmission, a stable structure, and convenient and stable lifting operation.

[0024] In some embodiments, a rotating platform 7 is disposed above the platform body 1, and a movable groove 701 is opened at the upper end of the rotating platform 7; the rotating support assembly includes: an annular rail 702, which is fixed to the bottom of the movable groove 701; and a plurality of balls 703, which are arranged in a ring and rotatably connected to the bottom of the rotating platform 7, and the balls 703 are all rolledly connected to the annular rail 702.

[0025] In this embodiment, since the ball bearing 703 and the annular rail 702 form a rolling contact, the rotational friction is greatly reduced, and the stability of the support for the rotating platform 7 is improved. Therefore, by setting the rotational support component, the rotational drive component and the rotating platform 7 in cooperation, the rotating platform 7 adopts the support method of the ball bearing 703 and the annular rail 702, so that the rotating platform 7 rotates flexibly and smoothly.

[0026] In some embodiments, both the rotary support assembly and the rotary drive assembly are located below the rotary platform 7, for stable support and adjustment of the rotary support angle of the rotary platform 7; the rotary drive assembly includes: a brake motor 704, fixed to the lower end of the platform body 1; a drive shaft 705, fixed to the power end of the brake motor 704, and the drive shaft 705 rotatably extends through the upper part of the platform body 1; a main gear 706, fixed to the upper end of the drive shaft 705; the rotary drive assembly also includes: a support shaft 707, one end of which is fixed to the lower middle part of the rotary platform 7, and the other end of the support shaft 707 is rotatably connected to the bottom of the movable groove 701; a secondary gear 708, fixedly sleeved around the support shaft 707, and the secondary gear 708 meshes with the main gear 706.

[0027] In this embodiment, the rotary drive assembly is used to drive the rotary platform 7 to rotate precisely. Since the brake motor 704 is fixed below the platform body 1, when the brake motor 704 is activated, power is transmitted to the main gear 706 through the drive shaft 705, driving the meshing secondary gear 708 to rotate, thereby driving the entire rotary platform 7 to rotate around the center line of the support shaft 707. When positioning is required, the brake motor 704 can brake immediately, locking the rotary platform 7 at the required angle, which facilitates convenient adjustment of the operator's working angle position.

[0028] In some embodiments, the sliding drive assembly is provided in two sets, distributed left and right on both sides of the lower end of the bottom frame 2, for convenient and labor-saving sliding adjustment of the support position of the lifting platform; each sliding drive assembly includes: a concave frame 8, fixed to the lower end of the bottom frame 2; a roller 801, rotatably connected to the concave frame 8; a drive motor 802, fixed to the outside of the concave frame 8, the power end of the drive motor 802 is fixed with a rotating shaft, the rotating shaft rotatably passes through the concave frame 8, and one side of the roller 801 is fixed to the end of the rotating shaft; a second guide rail 9 is provided below each roller 801, and the roller 801 is rotatably connected to the second guide rail 9.

[0029] In this embodiment, the drive motor 802 is started, and the drive motor 802 drives the roller 801 to rotate through the rotating shaft, which in turn drives the roller 801 to roll on the second guide rail 9, thereby realizing the linear movement of the entire lifting platform, which facilitates easy and labor-saving movement and adjustment of the working position of the lifting platform.

[0030] In summary, the lifting, rotating and translating functions of a single device are realized in sequence, which significantly improves the adaptability and operating range of the equipment. Moreover, the layout of each component is reasonable, which ensures the compactness of the overall structure while realizing complex functions and saving space. It is particularly suitable for flexible production scenarios such as automated production lines, assembly stations and logistics transfer that require multi-degree-of-freedom position adjustment, and is especially suitable for meeting the glue application needs of different models of vehicles with large size differences.
