Description

Technical Field

[0001] This invention belongs to the field of storage devices, and in particular relates to a method for constructing a three-dimensional storage device and a three-dimensional storage device. Background Technology

[0002] In existing technologies, automated storage and retrieval systems (AS / RS) can be built to improve space utilization when stacking specific equipment of specific dimensions. However, existing AS / RS systems are difficult to adapt to the storage needs of equipment with significant deviations from specific dimensional specifications.

[0003] For example, Chinese invention patent application CN107521891A, published on December 29, 2017, discloses an automated warehouse, including shelves with several layers of racks, elevators, and transport trolleys. Adjacent rows of shelves share a single aisle, with tracks for the transport trolleys running in the X and Y directions within the aisle. The shelves themselves also have tracks for the transport trolleys running in the Y direction. When storing goods, the elevator first transports the transport trolleys to each layer, and then the transport trolleys travel along the tracks to place the goods onto the racks.

[0004] In the aforementioned Chinese invention patent application, on the one hand, the use of transport trolleys cannot achieve the stacking of materials; on the other hand, a single rack can only store specific materials of a specific size and cannot be used to store other materials, nor can it simultaneously accommodate various materials with large size and specification deviations. Furthermore, the storage space of the aforementioned automated warehouse is already completely fixed; whether expanding or shrinking the storage space, the cost of modifying the automated warehouse is too high, making it unsuitable for modification.

[0005] The existing factory building is equipped with such Figures 1-4 The ground rail 1 shown has a converging groove 1-1, and its upper surface is flush with the ground to avoid affecting the normal movement of vehicles within the factory building. When storing materials with large dimensional deviations, such as containerized storage units, overhead cranes are often used to temporarily stack the materials on the factory floor. To prevent the materials from tipping over, the stacking height is limited, resulting in low space utilization. Due to the special nature of materials stored in the factory, when necessary, at least some materials need to be removed from the factory to convert the original storage area into other functional areas.

[0006] Therefore, there is an urgent need for a method to renovate existing factory buildings in order to improve space utilization. Summary of the Invention

[0007] The purpose of this invention is to provide a method for constructing a three-dimensional storage device to solve the technical problem of low space utilization when storing materials in a factory.

[0008] The present invention also aims to provide a three-dimensional storage device to solve the technical problem of low space utilization when storing materials in a factory.

[0009] To achieve the above objectives, the technical solution of the three-dimensional storage device construction method provided by the present invention is as follows: A method for constructing a three-dimensional storage device includes the following steps: Step 1: Erect a rack on the factory floor. The rack includes pallets and beams and uprights to support the pallets. The pallets, beams, and uprights are detachably connected and form a storage area with the pallets and the corresponding area of ​​the ground below them. In the direction of the ground rail extension, the bottom of the corresponding upright on at least one side is fixedly connected to the ground rail by bolts. The bolt head is located in the groove of the ground rail, and the bolt thread passes through the corresponding hole on the upright and is connected to the nut. The spacing between the uprights on both sides can be adjusted as needed before the nut is tightened, thereby adjusting the floor area of ​​the rack. Step 2: Install a lifting mechanism to transport materials to pallets, and equip each storage area with a crane for transferring materials.

[0010] Furthermore, in step 1, one side of the column is connected to the ground rail by bolts, and the other side of the column is fixedly connected to the ground.

[0011] Furthermore, in step 1, in the direction of the ground rail extension, the pallet is composed of multiple rows of sub-pallets, and the crossbeam is composed of multiple sub-crossbeams connected together. The number of sub-pallets and sub-crossbeams is determined according to the spacing between the two side columns.

[0012] Furthermore, the lowest end of the corresponding column has a flange, and the flange hole of the flange constitutes the aforementioned through hole. In step 1, the bolt thread passes through the flange hole and is connected to the nut.

[0013] Furthermore, the lifting mechanism includes a lifting platform, a pulley assembly, and a winch. In step 2, the winch is placed outside the shelf and a counterweight is provided for the winch so that the wire rope of the winch is connected to the lifting platform after being reversed by the pulley assembly.

[0014] Furthermore, in step 1, concrete is first used to pour and lay the ground rails on the old factory floor to form a new factory floor with a level upper surface, and the shelves are erected on the new factory floor.

[0015] The beneficial effects of the three-dimensional storage device construction method provided by the present invention are as follows: a three-dimensional shelf can be built on the factory floor, which can store materials in different storage areas in different layers and categories. At the same time, the corresponding columns are connected to the ground rails by bolts, so that the floor area of ​​the shelf can be adjusted by moving the corresponding columns along the ground rails. This improves the space utilization rate when storing materials while modifying the floor area of ​​the shelf in a low-cost manner.

[0016] To achieve the above objectives, the technical solution of the three-dimensional storage device provided by the present invention is as follows: A three-dimensional storage device includes a floor rail with a converging groove, and a rack erected on the factory floor. The rack includes a pallet and beams and uprights for supporting the pallet, forming a storage area corresponding to the pallet and the ground below the pallet. The pallet, beams, and uprights are detachably connected. In the direction of the floor rail extension, the lowest end of at least one corresponding upright is fixedly connected to the floor rail by bolts. The bolt head is located in the converging groove, and the bolt shank passes through a corresponding hole on the upright and is connected to a nut to adjust the distance between the uprights on both sides before the nut is tightened, thereby adjusting the floor area of ​​the rack. The pallet is equipped with a lifting mechanism for lifting materials to the pallet, and each storage area is also equipped with a crane for transferring materials.

[0017] Furthermore, in the direction of the ground rail extension, the pallet is composed of multiple rows of sub-pallets, and the crossbeam is composed of multiple sub-crossbeams connected together.

[0018] Furthermore, the bottom end of the column connected to the ground rail has a flange, and the flange hole of the flange forms the aforementioned through hole. The bolt thread passes through the flange hole and is connected to the nut.

[0019] Furthermore, the lifting mechanism includes a lifting platform, a pulley assembly, and a winch. The winch is located outside the rack and is equipped with a counterweight. The winch's wire rope is connected to the lifting platform after being reversed by the pulley assembly.

[0020] The beneficial effects of the three-dimensional storage device provided by the present invention are as follows: a three-dimensional shelf can be built on the factory floor, which can store materials in different storage areas in different layers and categories. At the same time, the corresponding columns are connected to the ground rails by bolts. When needed, the floor area of ​​the shelf can be adjusted by moving the corresponding columns along the ground rails. Thus, the space utilization rate of stored materials can be improved while modifying the floor area of ​​the shelf in a low-cost manner. Attached Figure Description

[0023] To address the problems in the background art, the core inventive concept of this invention is to build a shelf on the factory floor and connect the shelf uprights to the ground rail with bolts, so as to adjust the shelf's footprint by sliding the uprights along the ground rail, thereby improving the space utilization rate when storing materials while modifying the shelf footprint in a low-cost manner.

[0024] The present invention will be further described in detail below with reference to the embodiments.

[0025] An embodiment of the method for constructing a three-dimensional storage device provided by the present invention.

[0026] Reference Figures 1-10 As shown, the method for constructing a three-dimensional storage device includes the following steps: Step 1: If there is no ground track 1 on the old factory floor, first pour concrete to lay the ground track 1 on the old factory floor to form a new factory floor with a level upper surface. If the ground track 1 has already been laid on the old factory floor, this step can be omitted. In this case, this method can also be called the renovation method of the old factory.

[0027] Step 2: Erect a shelf 2 on the factory floor where the floor rail 1 is laid. The shelf 2 includes a pallet and crossbeams 6 and uprights 5 for supporting the pallet. The pallet, crossbeams 6, and uprights 5 are detachably connected, forming a storage area with the pallet and the corresponding area of ​​the ground below the pallet. In the extension direction of the floor rail 1, the lowest end of at least one corresponding upright 5 is fixedly connected to the floor rail 1 by bolts. The bolt head is located in the groove 1-1 of the floor rail 1, and the bolt thread passes through the corresponding through hole on the upright 5 and is connected to the nut. This allows the spacing between the uprights 5 on both sides to be adjusted as needed before the nut is tightened, thereby adjusting the floor area of ​​the shelf 2. Preferably, the lowest end of the corresponding upright 5 has a flange, and the flange hole of the flange forms the through hole, allowing the bolt thread to pass through the flange hole and be connected to the nut. This design is simple and easy to operate.

[0028] Step 3: Set up a lifting mechanism 3 to transport materials 21 to the pallet, and configure a crane 4 for transferring materials 21 in each storage area.

[0029] In step 2, preferably, one side of the column 5 is connected to the ground rail 1 by bolts, and the other side of the column 5 is fixedly connected to the ground. The column 5 can be fixed to the ground with concrete, or a pit can be dug in the ground and bolts can be pre-embedded. After the pit is filled with concrete, the bolt thread protrudes from the ground and passes through the corresponding hole on the column 5 and is connected to a nut.

[0030] Of course, the columns 5 on both sides can also be connected to the ground rail 1 with bolts. In this case, after the three-dimensional storage device is completely removed, the factory floor can be restored to its original state.

[0031] The lifting mechanism 3 includes a lifting platform 15, a pulley assembly 13, and a winch. In step 3, the winch is positioned outside the shelf 2, and a counterweight 10 is provided for the winch, so that the winch's wire rope 12 is connected to the lifting platform 15 after being reversed by the pulley assembly 13. Simultaneously, the highest position that the lifting platform 15 can reach is aligned with the uppermost pallet to facilitate subsequent loading and unloading of materials 21.

[0032] Reference Figures 1-10 As shown, taking a three-dimensional storage device with two layers of pallets and three storage areas as an example, the specific process of storing materials 21 in a three-dimensional storage device constructed according to the three-dimensional storage device construction method of the present invention will be introduced.

[0033] First, the transfer vehicle 20 transfers the material 21 to the shelf 2. Then, the staff determines which storage area the material 21 should be stacked in. If the material 21 should be stacked in the bottom storage area, the bottom overhead crane directly lifts the material 21 and stacks it. If the material 21 should be stacked in other storage areas, the bottom overhead crane lifts the material 21 onto the lifting platform 15. The lifting platform 15 lifts the material 21 to the corresponding storage area, and the corresponding overhead crane lifts the material 21 from the lifting platform 15 into the corresponding storage area and stacks it, so as to store the material 21 in layers and categories.

[0034] The specific process of retrieving material 21 is the opposite of the specific process of storing material 21, and will not be described in detail here.

[0035] When you want to modify the footprint of shelf 2, you can loosen the nuts on the uprights 5 connected to the ground rail 1 and move the uprights 5 along the ground rail 1 to change the footprint of shelf 2. Of course, you will also need to make adaptive adjustments to the pallets, beams 6, and overhead crane. When one upright 5 is connected to the ground and fixed in place, you do not need to adjust that upright 5; you only need to adjust the uprights 5 on the other side. This helps reduce the difficulty of modification and save costs.

[0036] After reducing the footprint of shelf 2, the area corresponding to the reduced footprint can be restored to the factory floor, thus realizing other functional areas that the original factory floor could provide. After expanding the footprint of shelf 2, shelf 2 can store more materials 21.

[0037] To further reduce the difficulty of the renovation and save costs, preferably, in step 2, in the direction of the extension of the ground rail 1, the pallet is composed of multiple rows of sub-pallets, and the beam 6 is composed of multiple sub-beams connected together. The number of sub-pallets and sub-beams is determined according to the distance between the two uprights 5, so that the floor space of the rack 2 can be adjusted by increasing or decreasing the number of sub-pallets and sub-beams during the renovation, without having to replace the entire pallet and the entire beam 6, which helps to reduce the renovation cost. Adjacent sub-beams are preferably connected by flanges, and adjacent sub-pallets may not be connected. The sub-pallets are connected to the beam 6 and / or uprights 5 by bolts.

[0038] Embodiments of the three-dimensional storage device provided by the present invention: The three-dimensional storage device provided by the present invention can be constructed by the method in the embodiment of the three-dimensional storage device construction method of the present invention.

[0039] like Figures 1-10As shown, in a basic embodiment, the three-dimensional storage device includes a ground rail 1 with a converging groove 1-1 and a shelf 2 erected on the factory floor. The shelf 2 includes a pallet and crossbeams 6 and uprights 5 for supporting the pallet, so as to form a storage area corresponding to the pallet and the ground below the pallet. The pallet, crossbeams 6 and uprights 5 are detachably connected. In the extending direction of the ground rail 1, the lowest end of at least one corresponding upright 5 is fixedly connected to the ground rail 1 by bolts, with the bolt heads located in the converging groove 1-1. The screw passes through the corresponding hole on the upright 5 and connects to the nut, so as to adjust the distance between the two uprights 5 before the nut is tightened, thereby adjusting the floor space of the shelf 2. The pallet is equipped with a lifting mechanism 3 for lifting the materials 21 to the pallet. Each storage area is also equipped with a crane 4 for transferring the materials 21. The lifting area of ​​the crane 4 covers the storage area of ​​the layer and the lifting platform 15 of the lifting mechanism 3, so as to achieve seamless connection of horizontal and vertical transfer, and realize three-dimensional high-density storage and efficient transfer of materials 21. A staircase 8 can also be set on the side of the shelf 2 so that the staff can reach the storage area corresponding to the pallet through the staircase 8.

[0040] Preferably, in the direction of the extension of the ground rail 1, the pallet is composed of multiple rows of sub-pallets, and the beam 6 is composed of multiple sub-beams connected together. This allows the floor space of the shelf 2 to be adjusted by increasing or decreasing the number of sub-pallets and sub-beams during the renovation, without having to replace the entire pallet and the entire beam 6, which helps to reduce the renovation cost.

[0041] Among them, such as Figures 1-4 As shown, the ground rail 1 is a steel guide rail with an inverted T-shaped cross section, which is laid in the factory building in an array by pouring concrete. The upper surface of the ground rail 1 is arranged horizontally and is flush with the ground.

[0042] The shelving unit 2 consists of uprights 5, beams 6, decks 7, stairs 8, and frames 9. The lowest end of each upright 5, connected to the ground rail 1, has a flange. The flange holes form the through holes described above. Bolts pass through these holes and are connected to nuts. The uprights 5, beams 6, decks 7, stairs 8, and frames 9 are assembled into a multi-layer shelving structure using a modular approach. All components are bolted together for easy disassembly when not in use. The deck 7 includes a connecting plate at the top and a support plate below it. The connecting plate is connected to the top of the corresponding upright 5 to enhance the structural strength of the shelving unit 2.

[0043] A hoistway and mounting base for the lifting mechanism 3 are provided on one side of the rack 2. Guide rail mounting bases for the traveling trolley 4 are provided on both sides of the top of each compartment of the rack 2 (a compartment is formed between the two decks 7, and a compartment is formed between the lowest deck 7 and the ground). The lifting mechanism 3 consists of a counterweight 10, a drive unit 11, a wire rope 12, a pulley assembly 13, a vertical guide rail 14, and a lifting platform 15. The counterweight 10 is used to balance the weight of the lifting platform 15 and the transported materials 21 during operation. The counterweight 10 can be composed of a steel base and concrete blocks and can be placed directly on the ground outside the hoistway of the lifting mechanism 3. For example, the upper surface of the steel base is provided with the mounting interface of the drive unit 11, and the inner side is provided with concrete blocks. The number of concrete blocks is determined according to the maximum load transported by the lifting mechanism 3. The drive unit 11 is a winch. The wire rope 12 on the winch passes over multiple sets of pulley assemblies 13 above the drive unit 11, changes direction, and connects to a fixed interface on the lifting platform 15. The winch rotates forward and backward to wind up and unwind the wire rope 12, thereby enabling the lifting platform 15 to move up and down. The vertical guide rail 14 is laid along the vertical tunnel to guide the up and down movement of the lifting platform 15. The wire rope 12, pulley assembly 13, and vertical guide rail 14 are all located on the outside of the lifting platform 15. Their installation positions do not interfere with the installation and operation areas of the overhead crane 4 in each compartment of the rack 2. The lifting platform 15 moves along the vertical guide rail 14 through the guide wheel device, so it can only move up and down along the vertical guide rail 14.

[0044] The traveling crane 4 consists of a horizontal guide rail 16, a trolley 17, a trolley 18, and a lifting device 19. The horizontal guide rail 16 is laid on both sides of the top of each cabin, covering the outer side of the cabin storage area and the operating area of ​​the lifting platform 15, and does not interfere with the operation of the lifting platform 15. The trolley 17 can run along the horizontal guide rail 16 between the cabin storage area and above the lifting platform 15. The trolley 18 is installed inside the trolley 17 and can run along the length of the trolley 17. The lifting device 19 is installed on the trolley 18, and its hook can run in the vertical direction.

[0045] The three-dimensional storage device of this invention can be modified from the existing floor rails 1 in the factory building, or the floor rails 1 can be re-laid in the existing factory building. It can be temporarily set up when needed to achieve three-dimensional high-density storage of materials 21. When not needed, it can be easily dismantled (completely or partially dismantled) to restore the functions of other areas of the factory building. The drive device 11 of the lifting mechanism 3 is placed directly on the factory floor by means of ballast counterweight 10, without the need for a fixed ground mounting base, and does not occupy valuable floor rail area, thus maximizing the use of the valuable floor rail area in the factory building. The vertical guide rails 14, wire ropes 12, and pulley assemblies 13 of the lifting mechanism 3 are all located on the outer side of the long side, without interfering with the operating area of ​​the traveling trolleys 4 in each compartment. The horizontal guide rails 16 of the traveling trolleys 4 in each compartment are laid on the outer side of the lifting platform 15, without affecting the vertical operation of the lifting platform 15, and can make its lifting range cover the area of ​​the lifting platform, thereby seamlessly connecting horizontal and vertical transportation and realizing efficient transportation of materials 21.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features, or organically combine different embodiments to create the embodiments shown in the accompanying drawings.
