Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to an adjustable lifting ladder structure. Background Technology

[0002] In modern industrial production, logistics warehousing, and construction, lifting platforms are widely used as important material handling equipment for the vertical transportation of goods. Traditional lifting platforms have many limitations in practical use, especially in terms of material limiting. During lifting, materials are prone to shifting due to swaying or inaccurate positioning, leading to unstable transportation and potentially causing safety accidents. To address these issues, some lifting platforms with adjustable limit devices have emerged on the market. While these devices improve material stability to some extent, their limiting structures are generally complex and mostly fixed, making it difficult to flexibly adjust to different material sizes and shapes, thus greatly limiting their applicability.

Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0016] To solve the above technical problems, such as Figure 1-2 As shown, this utility model designs an adjustable lifting ladder structure, including an adjustable limit component, a screw lifting adjustment mechanism, and two uprights 1. The two uprights 1 are arranged symmetrically to each other. The screw lifting adjustment mechanism is located between the two uprights 1. The screw lifting adjustment mechanism includes a lifting block 2 that can move up and down. A lifting plate 3 is provided on the front side of the lifting block 2. Two symmetrical support plates 4 are provided on the front side of the lifting plate 3. The support plates 4 are used to support the material frame. The up and down movement of the lifting block drives the lifting and transfer of the material frame.

[0017] The adjustable limiting assembly includes a first horizontal bar 5, a second horizontal bar 6, a third horizontal bar 7, a first vertical bar 8, a second vertical bar 9, a limiting rod 10, and a limiting plate 11. The first horizontal bar 5, second horizontal bar 6, third horizontal bar 7, first vertical bar 8, and second vertical bar 9 are all provided with oblong holes. The oblong holes of the first horizontal bar 5 and second horizontal bar 6 are through-holes in the front-to-back direction, the oblong holes of the third horizontal bar 7 and second vertical bar 9 are through-holes in the vertical direction, and the oblong hole of the first vertical bar 8 is through-holes in the left-to-right direction. One end of the first horizontal bar 5 is connected to the outer surface of the upright 1. The second horizontal bar 6 is located below and parallel to the first horizontal bar 5. A vertical rod 8 is perpendicular to the first horizontal rod 5 and connected to the oblong hole of the first horizontal rod 5 through a bolt assembly. A second vertical rod 9 is perpendicular to the second horizontal rod 6 and connected to the oblong hole of the second horizontal rod 6 through a bolt assembly. When the bolt and nut assembly is tightened, the position of the first vertical rod 8 is fixed. When the assembly is loosened, the two vertical rods can be adjusted in the left and right directions. The limiting plate 11 is connected to the oblong hole of the first horizontal rod 5 through a bolt assembly. When the corresponding bolt assembly is loosened, the limiting plate 11 can be adjusted in the front and back directions. The distance between the two limiting plates 11 is adapted to the width of the corresponding material to achieve accurate positioning.

[0018] Each second vertical rod 9 is connected to two third horizontal rods 7, which are arranged parallel to each other. The third horizontal rods 7 are also fitted into the oblong holes of the second vertical rods 9 via bolt assemblies. When loosened, the third horizontal rods 7 can be adjusted back and forth. The bottom end of the limiting rod 10 is inserted into the oblong hole of the third horizontal rod 7, and the limiting block is located between the two limiting rods 10. Specifically, the bottom end of the limiting rod 10 is provided with a coaxial screw. The screw passes through the oblong hole of the third horizontal rod 7 and is locked by a nut. Therefore, the installation method of the limiting rod 10 is relatively simple. At the same time, the limiting rod 10... When loosening the connection, the third horizontal bar 7 can be individually adjusted left and right precisely to match the width of the material. During the lifting process, the limit bar 10 can effectively prevent the material from shaking or deviating, ensuring stable material transportation and significantly improving the safety and reliability of the lifting platform. The adjustable limit component, through the unique design of multiple horizontal bars, vertical bars and limit bar 10, combined with the cooperation of the waist-shaped hole and bolt assembly, can be quickly adjusted in multiple directions according to the size and shape of different materials, making it suitable for materials of various widths and heights, and significantly improving the applicability of the lifting platform.

[0019] The connections between components are achieved through bolt assemblies, resulting in a simple structure that is easy to assemble and disassemble. Users can quickly adjust the position of the limit components according to actual needs without requiring complex tools or professional skills, greatly improving operational convenience.

[0020] In this embodiment, it is further preferred that the lead screw lifting adjustment mechanism also includes a drive motor 12, a lead screw 13, and a support base 14. Two U-shaped seats 15 are provided between the two uprights 1, and a support base 14 is provided on the inner side of each U-shaped seat 15. The lead screw 13 is engaged with the bearing in the support base 14. The lead screw 13 is set perpendicular to the horizontal plane. The drive motor 12 is used to drive the lead screw 13 to rotate. The inner side of the lifting block 2 is connected to the lead screw 13 through a lead screw nut. The thread accuracy and fit accuracy of the lead screw 13 can ensure that the lifting block 2 can achieve very precise height adjustment during the up and down movement. The rotation of the lead screw 13 can be smoothly converted into the linear motion of the lifting block 2. This smooth lifting performance is particularly important when carrying fragile items, precision instruments, or other materials with high stability requirements, and can effectively reduce the risk of damage caused by shaking or impact.

[0021] In this embodiment, it is further preferred that the screw lifting adjustment mechanism also includes a guide rail 16 and a slider 17. The slider 17 is symmetrically arranged on the left and right sides of the rear side of the upgrading plate. The guide rail 16 is arranged on the front side of the upright 1. The guide rail 16 is arranged parallel to the screw 13. The slider 17 is slidably connected to the guide rail 16. The cooperation between the guide rail 16 and the slider 17 can further ensure the precise vertical movement of the lifting plate 3, reduce lateral swaying, thereby improving the positioning accuracy of the lifting ladder, and making the lifting plate 3 more stable and smooth during the up and down movement.

[0022] In this embodiment, a further preferred embodiment has a support rod 18 on the rear side of the upright 1, and an mounting plate 19 between the two support rods 18. The drive motor 12 is mounted on the mounting plate 19, and the output shaft of the drive motor 12 faces downward and is connected to a drive wheel 20. The bottom end of the lead screw 13 is connected to a synchronous pulley 21, and the drive wheel 20 and the synchronous pulley 21 are connected by a synchronous belt. This layout not only facilitates the installation and maintenance of the motor, but also allows for better integration with other components, improving the overall coordination of the equipment. Synchronous belt drive has advantages such as accurate transmission ratio, high transmission efficiency, and low noise, which can ensure that the elevator maintains good transmission performance during operation and reduce energy loss.
