Description

Technical Field

[0001] This utility model relates to the technical field of cargo lifting devices, specifically a multi-level mezzanine rack lifting device. Background Technology

[0002] Mezzanine storage racks are multi-level storage systems built with medium or heavy-duty shelving units as the supporting structure, combined with steel floor slabs. They utilize the rack uprights as load-bearing components for the floor, and improve space utilization through layered design. They are suitable for scenarios with high warehouse heights and where manual handling of small to medium-sized goods is required. The main structure uses cold-rolled steel floor slabs, checkered steel floor slabs, or steel grating floor slabs, featuring uniform load-bearing capacity and high stability.

[0003] Traditional tilting rack lifting devices have a fixed tilt angle and cannot adjust the tilt angle of goods, thus they are only suitable for lifting racks at specific angles. To address this issue, a multi-level mezzanine rack lifting device is proposed. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a multi-level mezzanine rack lifting device.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a multi-level mezzanine rack lifting device, including a U-shaped support and two crossbars, an adjustment component is fixedly installed at the center position of both sides of the top of the U-shaped support, the adjustment component includes a vertical rod fixedly installed at the top of the U-shaped support, a rotating shaft is rotatably connected to the top of the vertical rod, a first connecting frame is fixedly installed at the center position of the bottom of the crossbars, and a first adjustment frame is rotatably connected inside the first connecting frame;

[0006] The top of the U-shaped bracket is slidably connected to both sides of a second connecting frame. The second connecting frame is rotatably connected to a second adjusting frame. One side of the first adjusting frame is rotatably connected to the second adjusting frame. A threaded block is rotatably connected at the junction of the first adjusting frame and the second adjusting frame. A threaded rod is installed on the radial inner wall of the threaded block through internal and external thread engagement. One side of the rotating shaft is drively connected to the threaded rod.

[0007] Preferably, the second connecting frame slides on the surface of the U-shaped bracket through the mutual cooperation of the threaded block and the threaded rod.

[0008] Preferably, a third connecting frame is fixedly installed at the corner of the top of the U-shaped bracket, and a rotating block is rotatably connected inside the third connecting frame, with the other side of the rotating block connected to the cross frame.

[0009] Preferably, a groove is provided on one side of each of the two crossbars, and a threaded frame is slidably connected inside the groove. A lead screw is installed on the radial inner wall of the threaded frame through internal and external thread engagement, and a loading plate is fixedly installed between the two threaded frames.

[0010] Preferably, a slope plate is fixedly installed on one side of the U-shaped bracket, and a number of anti-slip strips are fixedly installed on the surface of the slope plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The threaded rod rotates under the drive of the first servo motor. The rotating threaded rod interacts with the threaded block, causing the threaded block to slide along the surface of the U-shaped bracket under the support of the second adjusting frame and the second connecting frame. This allows for adjustment of the tilt angle of the first adjusting frame, thus enabling adjustment of the tilt angle of the crossbeam. This makes it suitable for various cargo lifting scenarios with different tilt angles. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figures 1-3 As shown, this utility model provides a multi-level mezzanine rack lifting device, including a U-shaped support 1 and two horizontal frames 4. An adjustment component is fixedly installed at the center of both sides of the top of the U-shaped support 1. The adjustment component can adjust the tilt angle of the two horizontal frames 4. The adjustment component includes a vertical rod 15 fixedly installed at the top of the U-shaped support 1. A first servo motor is fixedly installed on one side of the vertical rod 15 to drive the rotating shaft 14 to rotate. However, as prior art, it is not shown in the accompanying drawings. The top of the vertical rod 15 is rotatably connected to the rotating shaft 14. The rotating shaft 14 can rotate clockwise or counterclockwise under the drive of the first servo motor. A first connecting frame 8 is fixedly installed at the center of the bottom of the horizontal frame 4. A first adjustment frame 9 is rotatably connected inside the first connecting frame 8.

[0020] Both sides of the top of the U-shaped bracket 1 are slidably connected to a second connecting frame 11. A second adjusting frame 10 is rotatably connected inside the second connecting frame 11. The second connecting frame 11 slides on the surface of the U-shaped bracket 1 through the cooperation of a threaded block 12 and a threaded rod 13. One side of the first adjusting frame 9 is rotatably connected to the second adjusting frame 10. A threaded block 12 is rotatably connected at the junction of the first adjusting frame 9 and the second adjusting frame 10. When the rotating shaft 14 rotates clockwise, the threaded block 12 slides on the surface of the threaded rod 13 towards one side of the U-shaped bracket 1 under the support of the second adjusting frame 10 and the second connecting frame 11. During the sliding process, the tilt angle of the first adjusting frame 9 increases, which in turn increases the tilt angle of the cross frame 4. Conversely, when the threaded block 12 slides in the opposite direction on the surface of the threaded rod 13, the tilt angle of the first adjusting frame 9 decreases, which in turn decreases the adjustment angle of the cross frame 4. The threaded rod 13 is installed on the radial inner wall of the threaded block 12 through internal and external thread engagement. One side of the rotating shaft 14 is connected to the threaded rod 13 for transmission. A third connecting frame 3 is fixedly installed at the corner of the top of the U-shaped bracket 1. A rotating block 16 is rotatably connected inside the third connecting frame 3. The other side of the rotating block 16 is connected to the cross frame 4.

[0021] There are grooves on one side of the two crossbars 4 facing each other. Threaded brackets 6 are slidably connected inside the grooves. A lead screw 5 is installed on the radial inner wall of the threaded bracket 6 through internal and external thread engagement. A loading plate 7 is fixedly installed between the two threaded brackets 6.

[0022] By adopting the above technical solution, the lead screw 5 rotates clockwise or counterclockwise under the drive of the second servo motor. When the lead screw 5 rotates clockwise, the threaded bracket 6 moves upward with the loading plate 7 attached inside the slide groove. Conversely, when the lead screw 5 rotates counterclockwise, the threaded bracket 6 moves downward with the loading plate 7 attached inside the slide groove.

[0023] A ramp 2 is fixedly installed on one side of the U-shaped bracket 1, and several anti-slip strips 17 are fixedly installed on the surface of the ramp 2.

[0024] By adopting the above technical solution, the ramp 2 can facilitate the loading and unloading of goods by the flatbed truck, and the anti-slip strip 17 can prevent the surface of the ramp 2 from becoming slippery.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
