Description

Technical Field

[0001] This utility model belongs to the field of shelving, specifically, it relates to a shelving device for loading and unloading goods. Background Technology

[0002] In warehousing, logistics, and manufacturing, loading, unloading, and placement of goods are crucial aspects of material management. To improve efficiency, shelving structures are often used to store containers in layers. However, most existing shelving systems use fixed planar structures, requiring manual lifting or simple sliding rails to place containers, making it difficult to adapt to the requirements of automated guidance at different angles.

[0003] On the other hand, when the cargo box slides into the shelf along the inclined track, if it is not leveled in time, its bottom will remain tilted, which is not conducive to the stable placement of goods and can easily cause safety hazards such as tipping and jamming during subsequent retrieval and placement. At the same time, although some devices are equipped with guide wheels to reduce friction, they lack a leveling mechanism and an automatic reset structure, which means that the cargo box pushing process still requires manual intervention, resulting in a low degree of automation.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cargo loading and unloading rack device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A cargo loading and unloading racking device includes: a support frame, a back panel being provided on the back of the support frame, and the interior of the support frame being divided into four spaces;

[0008] Two guide structures are installed at the bottom of each space. The guide structures are inclined downward from front to back in the space to guide the cargo box to slide and make the cargo box contact the back panel.

[0009] Each space is equipped with a sliding push mechanism for flattening the tilted cargo box. The push mechanism includes two connecting frame groups located in the space, and a U-shaped frame is fixedly connected between each two adjacent connecting frame groups.

[0010] The connecting frame group includes two connecting frames, with several rollers rotatably connected inside the connecting frames, and a connecting rod connecting two adjacent connecting frames.

[0011] Optionally, the guide structure includes a mounting frame, with several guide wheels rotatably connected inside the mounting frame, and L-shaped plates fixedly connected to both ends of the mounting frame, with the L-shaped plates resting on top of the bracket.

[0012] Optionally, a straight groove is provided through the vertical direction of the bracket, a guide rod is installed inside the straight groove, and a guide hole adapted to the guide rod is provided through the opposite side of the U-shaped frame.

[0013] A servo motor is fixedly connected to the top of the bracket, and a screw is fixedly connected to the output end of the servo motor. A threaded hole adapted to the screw is opened through the opposite side of the U-shaped frame. The servo motor drives the screw to rotate, thereby driving the U-shaped frame to achieve linear reciprocating motion along the guide rod, so as to push the cargo box from an inclined state to a horizontal state.

[0014] Optionally, a number of buffer blocks are fixedly connected to the top of the U-shaped frame, with the buffer blocks facing downwards from the support. The buffer blocks are made of rubber or elastomer material and are used to absorb impact force when the U-shaped frame moves to the end.

[0015] Optionally, casters are fixedly connected to the four corners below the bracket.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0017] By incorporating a front-to-back inclined guide structure within the rack, and arranging several rotating guide wheels within the guide structure's mounting frame, the cargo box can automatically and smoothly slide into the preset space under gravity during loading, gradually approaching the back panel for precise positioning. This eliminates the need for manual support and adjustment, significantly reducing operational labor intensity. Furthermore, a supporting pushing mechanism automatically and smoothly pushes the tilted cargo box to a horizontal position after it slides in, ensuring the bottom of the cargo box fully contacts the rack platform, forming stable support and reducing slippage, tilting, or tipping caused by the bottom inclination. This enhances the safety of goods storage and the overall structural reliability.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-3 As shown, this embodiment provides a cargo loading and unloading rack device, including a support 1. A back plate 2 is provided on the back of the support 1 to form a limiting support when a cargo box is pushed in. The interior of the support 1 is divided into four independent spaces, each space is used to place a single cargo box to achieve simultaneous loading and unloading of multiple boxes.

[0028] Two guide structures are installed at the bottom of each space. These guide structures are arranged downwards from front to back, forming a slide at a certain angle. The cargo box can slide into the space along the slide of the guide structure and automatically approach the back panel 2 under the action of gravity, achieving automatic positioning and arrangement. This structural design can effectively reduce the offset or jamming problems caused by tilted stacking of cargo boxes, and improve loading and unloading efficiency and neatness.

[0029] Furthermore, the guide structure includes a mounting frame 7, with several guide wheels 8 rotatably connected inside the mounting frame 7 to reduce frictional resistance and ensure smooth sliding when the cargo box slides in. L-shaped plates 9 are fixedly connected to both ends of the mounting frame 7, supporting the bracket 1 above them to enhance the stability of the mounting frame 7 and prevent displacement after prolonged use.

[0030] Each compartment has an internal sliding mechanism for leveling tilted containers. The mechanism comprises two connecting frame groups arranged along the length of the compartment, with a U-shaped frame 4 fixedly connected between each pair of adjacent connecting frame groups. Each connecting frame group includes two parallel connecting frames 3, with several rollers 5 rotatably mounted inside to provide support and guidance during the pushing process. Two adjacent connecting frames 3 are fixedly connected by a connecting rod 6, creating a stable, linked structure that ensures synchronized movement as the U-shaped frame 4 moves.

[0031] In this embodiment, a vertical groove is formed through the support 1, and a guide rod 10 is slidably installed inside the groove. Guide holes adapted to the guide rod 10 are formed through the opposite sides of the U-shaped frame 4, ensuring smooth movement of the U-shaped frame 4 along a fixed direction through the guide engagement. A servo motor 11 is fixedly connected to the top of the support 1, and a screw 12 is fixedly connected to the output end of the servo motor 11. Threaded holes adapted to the screw 12 are formed through the opposite sides of the U-shaped frame 4.

[0032] When the servo motor 11 starts, it drives the screw 12 to rotate, and the U-shaped frame 4 achieves linear reciprocating motion along the guide rod 10 through threaded transmission. During the pushing process, the U-shaped frame 4 drives the connecting frame group to move forward step by step, pushing the cargo box, which was originally placed at an incline along the guide structure, forward until the bottom of the cargo box completely leaves the incline section and transitions to the horizontal section, thus completing the leveling operation.

[0033] In this embodiment, to prevent the U-shaped frame 4 from impacting the support 1 structure due to inertia when it moves to the end, several buffer blocks 13 are fixedly connected above the U-shaped frame 4, with the buffer blocks 13 facing downwards from the support 1. The buffer blocks 13 are made of rubber or elastomer material, which can effectively absorb the impact force when the U-shaped frame 4 reaches its limit position, achieve flexible limiting, reduce structural damage, and improve operational stability.

[0034] In addition, to improve the mobility and layout flexibility of the device, casters 14 are fixedly connected to the four corners of the support frame 1. The casters 14 can roll in all directions and are equipped with a self-locking device, which makes it convenient for operators to move the device between different work positions and fix it in place during use, ensuring operational safety.

[0035] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
