Description

Technical Field

[0001] This invention relates to the field of shelving technology, specifically to a vertical shelving unit. Background Technology

[0002] Vertical racking is an important tool for improving warehouse efficiency. However, in small and medium-sized warehouses, the storage and retrieval of goods using vertical racking mostly require manual handling. When storing and retrieving goods at higher levels, ladders are needed. Furthermore, the spacing between each layer cannot be adjusted according to the height of the goods, which consumes a lot of physical labor, has a low level of automation, wastes limited space, and poses safety hazards. Therefore, a vertical racking system is proposed to address the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a vertical shelving unit to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An upright rack includes a support frame and a loading mechanism. The support frame includes two front uprights and two rear uprights. A first crossbeam is fixedly connected between the front uprights and the rear uprights. The front uprights are provided with opening slots. The front uprights, the first crossbeam, and the loading mechanism are slidably connected. The loading mechanism is provided with a power lifting mechanism. The loading mechanism moves horizontally out through the opening slots and is raised or lowered to the required height.

[0006] Preferably, the opening slot extends through the front column to the left and right, the lower end face of the opening slot is on the same plane as the upper end face of the first crossbeam, and the cargo loading mechanism is slidably connected to the plane.

[0007] Preferably, the support frame further includes an inclined beam, which is fixedly connected to the front column, the rear column, and the first crossbeam, so as to better support the first crossbeam, so as to bear heavier goods and improve safety.

[0008] Preferably, the support frame further includes a second crossbeam, which is fixedly connected to the front column and the rear column to better limit the movement of the cargo-carrying mechanism and improve stability.

[0009] Preferably, the support frame has load-bearing rods fixedly connected to its left and right outer sides, the power lifting mechanism is a hydraulic lifting mechanism, the hydraulic rod is rotatably connected to the load-bearing rod, the output end of the hydraulic rod is fixedly connected to a first connecting rod, and the other end of the first connecting rod is rotatably connected to the cargo loading mechanism.

[0010] Preferably, there are four hydraulic rods, two of which are symmetrically arranged on the left and right sides.

[0011] Preferably, the cargo-carrying mechanism includes a cargo-carrying platform, a second connecting rod, and a sliding wheel. One end of the second connecting rod is fixedly connected to the side of the cargo-carrying platform, and the other end of the second connecting rod is rotatably connected to the sliding wheel. The first crossbeam and the front column are provided with sliding grooves, and the cargo-carrying platform slides horizontally along the sliding grooves through the sliding wheel, which can reduce friction and carry heavier goods.

[0012] Preferably, there are two hydraulic rods and two first connecting rods. The two first connecting rods are symmetrically and rotatably connected to the front end of the cargo-carrying platform. There are three second connecting rods and sliding wheels arranged on each side of the cargo-carrying platform. The width of the sliding wheel close to the front column is smaller than the width of the sliding wheel close to the rear column. The width of the opening groove is between the width of the sliding wheel close to the front column and the width of the sliding wheel close to the rear column. The front-end sliding wheel passes through the opening groove, and the rear-end sliding wheel cannot pass through the opening groove. A vertically communicating groove in the shape of a "convex character" is provided in the working area of the front column. The diameter of the second connecting rod close to the front column is larger than the diameter of the second connecting rod close to the rear column. The second connecting rod of the front column cannot pass through the vertically communicating groove. The middle sliding wheel has the same size as the sliding wheel close to the front column, and the middle second connecting rod has the same size as the second connecting rod close to the front column. When the middle sliding wheel passes through the opening groove, the rear-end sliding wheel enters the vertically communicating groove. The second connecting rod close to the rear column is fixedly connected with a limiting rod of the same diameter. The limiting rod, the rear-end sliding wheel, and the rear-end second connecting rod are slidably connected to the vertically communicating groove. The limiting rod prevents the cargo-carrying platform from tilting forward and backward, ensuring the stable lifting of the cargo-carrying platform. Above the through groove of the front column through which the limiting rod passes, there is a hinged flap. A switch through groove is provided on the inner side of the front column. A slider is slidably connected to the switch through groove. The side of the flap is hinged to the slider. When the slider slides from one side of the switch through groove to the other side, the flap rotates 90 degrees. A sliding switch is fixedly connected to the slider.

[0013] Preferably, the number of the first crossbeams is more than the number of the cargo-carrying platforms, and the distances between the multiple first crossbeams are different. Suitable first crossbeams can be selected according to the heights of different goods, further saving space.

[0014] Preferably, both the sliding switch and the front-end second connecting rod are fixedly connected with magnets. The two magnets attract each other. When the front-end sliding wheel moves out of the support frame, the flap is opened to facilitate the passage of the rear-end sliding wheel. When the front-end sliding wheel enters the support frame, the flap is closed, realizing the automatic opening and closing of the flap without manual operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, by setting a power lifting mechanism and an opening slot in the front column, the cargo loading mechanism is slidably connected to the front column and the first crossbeam. It moves horizontally out through the opening slot and is raised and lowered to the required height, eliminating the need for a ladder to access high-rise goods, thus ensuring safety and improving space utilization.

[0017] 2. In this invention, by setting up an inclined beam, a second crossbeam, a sliding wheel, and a sliding groove, friction can be reduced, the first crossbeam can be better supported so as to bear heavier goods, the loading mechanism can be better limited, and safety and stability can be improved.

[0018] 3. In this invention, by setting up hydraulic rods, vertical connecting grooves, limit rods, baffles, switch grooves, sliders, sliding switches, magnets, and multiple first crossbeams with different spacings, the position of the loading platform can be adjusted according to different cargo heights, further saving space, improving the level of automation, reducing the overall weight, and saving costs.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-4 The present invention provides a first technical solution:

[0034] An upright rack includes a support frame 1 and a loading mechanism 2. The support frame 1 includes two front uprights 3 and two rear uprights 4. A first crossbeam 5 is fixedly connected between the front uprights 3 and the rear uprights 4. The front uprights 3 are provided with a through opening 6. The lower end face of the opening 6 is on the same plane as the upper end face of the first crossbeam 5. The loading mechanism 2 is slidably connected to the plane. The loading mechanism 2 is provided with a power lifting mechanism. The loading mechanism 2 moves horizontally out through the opening 6 and is raised or lowered to the required height.

[0035] The support frame 1 also includes a diagonal beam 7, which is fixedly connected to the front column 3, the rear column 4, and the first crossbeam 5. This diagonal beam 7 can provide better support for the first crossbeam 5, so as to bear heavier goods and improve safety.

[0036] The support frame 1 also includes a second crossbeam 8, which is fixedly connected to the front column 3 and the rear column 4 to better limit the loading mechanism 2 and improve its stability.

[0037] The power lifting mechanism is a hydraulic lifting mechanism, with two hydraulic rods 10 symmetrically arranged on the left and right sides. The support frame 1 has load-bearing rods 9 fixedly connected to the left and right outer sides. The hydraulic rods 10 are rotatably connected to the load-bearing rods 9. The output end of the hydraulic rods 10 is fixedly connected to the first connecting rod 11. The other end of the first connecting rod 11 is rotatably connected to the loading mechanism 2.

[0038] For lighter loads, an electric hydraulic rod can be selected; for heavier loads, a miniature hydraulic station can be selected.

[0039] The cargo-carrying mechanism 2 includes a cargo platform 12, a second connecting rod 13, and a sliding wheel 14. The side of the cargo platform 12 is fixedly connected to one end of the second connecting rod 13, and the other end of the second connecting rod 13 is rotatably connected to the sliding wheel 14. The first crossbeam 5 and the front column 3 are provided with sliding grooves 15. The cargo platform 12 slides horizontally along the sliding grooves 15 through the sliding wheel 14, which can reduce friction and carry heavier goods.

[0040] For ease of connection and processing, this design selects a through-hole slot 6. Alternatively, the slot 6 can be non-through-hole, with the first connecting rod 11 rotatably connected to the cargo loading mechanism 2. The first crossbeam 5 can also be internally slotted, with the front column 3, the first crossbeam 5, and the cargo loading mechanism 2 slidably connected.

[0041] Workflow: Connect the first connecting rod 11 to the cargo loading mechanism 2 of the storage and retrieval layer. Start the motor or micro hydraulic pump, extend the hydraulic rod 10, and drive the cargo loading mechanism 2 to slide horizontally outward through the opening slot 6 and descend to the required height. After storing or retrieving goods, reverse the motor or use the reversing valve of the micro hydraulic station to compress the hydraulic rod 10, and drive the cargo loading mechanism 2 to rise to the storage and retrieval layer. Then, slide horizontally inward through the opening slot 6 into the support frame 1 to realize the storage and retrieval of high-level goods. Since the hydraulic rod 10 is rotatably connected to the support frame 1, the hydraulic rod 10 will rotate parallel to the side of the support frame 1 while extending and retracting during operation. Therefore, only the operating space of the width of the cargo loading mechanism 2 is required, which improves the space utilization rate.

[0042] Please see Figure 3-12 The present invention provides another technical solution:

[0043] A vertical shelf, comprising a support frame 1, a loading platform 12, and a power lifting mechanism. The support frame 1 includes two front columns 3 and two rear columns 4. A first cross beam 5 is fixedly connected between the front column 3 and the rear column 4. A sliding groove 15 is provided on the first cross beam 5 and the front column 3. Three second connecting rods 13 and sliding wheels 14 are provided on each side of the loading platform 12. One end of the second connecting rod 13 is fixedly connected to the side of the loading platform 12, and the other end is rotatably connected to the sliding wheel 14. The sliding wheel 14 is slidably connected to the first cross beam 5 and the front column 3. The width of the sliding wheel 14 close to the front column 3 is smaller than the width of the sliding wheel 14 close to the rear column 4. An opening groove 6 is provided on the front column 3. The width of the opening groove 6 is between the width of the sliding wheel 14 close to the front column 3 and the width of the sliding wheel 14 close to the rear column 4. The front end sliding wheel 14 passes through the opening groove 6, and the rear end sliding wheel 14 cannot pass through the opening groove 6. A vertically communicating groove 16 in the shape of a "convex character" is provided in the working area of the front column 3. The diameter of the second connecting rod 13 of the front column 3 close to the front column 3 is larger than the diameter of the second connecting rod 13 of the front column 3 close to the rear column 4. The second connecting rod 13 of the front column 3 cannot pass through the vertically communicating groove 16. The middle sliding wheel (14) has the same size as the sliding wheel (14) close to the front column (3). The middle second connecting rod (13) has the same size as the second connecting rod (13) close to the front column (3). When the middle sliding wheel 14 passes through the opening groove 6, the rear end sliding wheel 14 enters the vertically communicating groove 16. The second connecting rod 13 close to the rear column 4 is fixedly connected with a limiting rod 17 of the same diameter. The limiting rod 17, the rear end sliding wheel 14, and the rear end second connecting rod 13 are slidably connected to the vertically communicating groove 16. The limiting rod 17 prevents the loading platform 12 from tilting forward and backward, ensuring the stable lifting of the loading platform 12. Above the through groove of the front column 3 through which the limiting rod 17 passes, a retaining piece 18 is hinged. A switch through groove 19 is provided on the inner side of the front column 3. A slider 20 is slidably connected to the switch through groove 19. The side of the retaining piece 18 is hinged to the slider 20. When the slider 20 slides from one side of the switch through groove 19 to the other side, the retaining piece 18 rotates 90 degrees. A sliding switch 21 is fixedly connected to the slider 20.

[0044] The power lifting mechanism selects a hydraulic lifting mechanism. One hydraulic rod 10 is symmetrically arranged on each side. The left and right outer sides of the support frame 1 are fixedly connected with a bearing rod 9. The hydraulic rod 10 is rotatably connected to the bearing rod 9. The output end of the hydraulic rod 10 is fixedly connected with a first connecting rod 11. The other end of the first connecting rod 11 is rotatably connected to the front end of the loading platform 12, saving cost and reducing the overall weight.

[0045] The number of the first cross beams 5 is more than the number of the loading platforms 12. The distances between multiple first cross beams 5 are different. The suitable first cross beam 5 can be selected according to the height of different goods, saving space.

[0046] Both the sliding switch 21 and the front second connecting rod 13 are fixedly connected to magnets 22. The two magnets 22 attract each other. When the front sliding wheel 14 moves out of the support frame 1, the attraction of the magnets 22 will open the baffle 18 to allow the rear sliding wheel 14 to pass through. After the front sliding wheel 14 enters the support frame 1, it will close the baffle 18, thus realizing the automatic opening and closing of the baffle 18 without manual operation.

[0047] Workflow: Connect the first connecting rod 11 to the loading platform 12 of the storage and retrieval layer. Start the motor or micro hydraulic pump, and the hydraulic rod 10 will extend, causing the loading platform 12 to slide horizontally outward. Because the two magnets 22 of the sliding switch 21 and the front second connecting rod 13 attract each other, the slider 20 slides from the inside of the switch slot 19 to the outside when the loading platform 12 slides outward. The baffle 18 rotates 90 degrees from the closed state to the open state, which facilitates the horizontal sliding of the limit rod 17 and the rear sliding wheel 14, and the second connecting rod 13 near the front column 3. The diameter of connecting rod 13 is larger than the diameter of the second connecting rod 13 near the rear column 4. Therefore, the second connecting rod 13 of the front column 3 prevents the front sliding wheel 14 from entering the vertical connecting slot 16. Since the width of the opening slot 6 is between the width of the sliding wheel 14 near the front column 3 and the width of the sliding wheel 14 near the rear column 4, the front sliding wheel 14 passes through the opening slot 6. The middle sliding wheel 14 and the rear sliding wheel 14 are in the sliding slot 15, preventing the loading platform 12 from tilting back and forth and keeping it horizontal. 4. When passing through the opening slot 6, the rear sliding wheel 14 enters the vertical connecting slot 16. The hydraulic rod 10 drives the loading platform 12 to descend to the required height. The rear sliding wheel 14, the rear second connecting rod 13, and the limiting rod 17 remain in the front column 3 and slide up and down along the vertical connecting slot 16. Because the limiting rod 17 is slidably connected to the vertical connecting slot 16, the rear second connecting rod 13 will not rotate, thus keeping the loading platform 12 horizontal, preventing it from tilting forward or backward, and ensuring that the loading platform 12 rises and falls smoothly. After storing or retrieving goods, the motor reverses the movement. The rotary or micro hydraulic station reversing valve compresses the hydraulic rod 10, driving the loading platform 12 to rise to the storage and retrieval layer. It slides horizontally into the support frame 1 through the opening slot 6. When the front second connecting rod 13 passes inward, the slider 20 slides from the outside to the inside of the switch slot 19, and the baffle 18 rotates 90 degrees from the open state to the closed state, preparing for the storage and retrieval of goods on other loading platforms 12. This realizes the automatic opening and closing of the baffle 18 without manual operation, saving two hydraulic rods, reducing the overall weight, saving costs, and improving stability.

[0048] When replacing the first crossbeam 5 according to different cargo heights, after storing or retrieving the cargo, toggle the sliding switch 21 to close the original storage / retrieval layer baffle 18 and open the new storage / retrieval layer baffle 18.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
