Description

Technical Field

[0001] The present invention relates to the technical field of storage shelves, and more particularly to a three-dimensional storage system for propylene carbonate processing raw materials. Background Art

[0002] Propylene carbonate is an important chemical raw material, widely used in battery electrolytes, solvents, polymer chemicals and other fields. Generally, mobile silos / turnover silos are used to store propylene carbonate raw materials. When needed, the raw materials are pushed to the mixing production process or other processes through the mobile silos / turnover silos for discharge.

[0003] Since the storage method of warehouses has developed from flat storage to high-rise three-dimensional storage, shelves have become the main body of three-dimensional warehouses, cooperating with stackers and other conveying mechanisms to achieve rapid storage and retrieval of goods.

[0004] After searching, the patent number CN117902212B discloses an automated vertical shelf and its storage method, which controls the up and down movement of each layer of the shelf so that the height of each layer of the shelf can fit the goods as much as possible. Then, the height of each layer of the shelf higher than the height of the goods can be superimposed on each other to form a new space. In this way, when taking out the goods at a specific position, by controlling the movement of each layer of the shelf, a new space is formed above the goods at the specific position, so that the goods at the specific position can be taken out.

[0005] This invention solves the problem of existing shelves requiring aisles for placing and retrieving goods at specific locations. However, a first hydraulic rod needs to be installed at the placement plate of each layer. When a single item is taken out, multiple first hydraulic cylinders need to work together synchronously. This results in excessive power-driven mechanical structures and cumbersome operation.

[0006] In addition, the placement plate is movable up and down, and relies on the first hydraulic cylinder to support the stored objects on the placement plate. During the entire storage process, the hydraulic cylinder is in a continuously started state, which wastes energy and has a certain impact on the storage safety of the goods.

[0007] To this end, we propose a three-dimensional storage system for propylene carbonate processing raw materials to address the above problems. Summary of the Invention

[0008] The object of the present invention is to provide a three-dimensional storage system for propylene carbonate processing raw materials to solve the technical defects proposed in the background technology.

[0010] The multiple loading plates of the single layer of each longitudinally arranged single-unit bracket are fixedly connected by a crossbeam plate. The front and rear ends of the crossbeam plate pass through the outer side of the loading plate and are provided with through holes. The tops of the transversely arranged single-unit brackets on the front and rear sides are both equipped with crossbeam plates and telescopic cylinders that move horizontally based on the crossbeam plates. The telescopic ends of the telescopic cylinders are fixed with hooks that match the through holes.

[0011] The loading and unloading unit includes a movable bracket and a movable box located on the movable bracket. A clamping assembly for fixing the storage cylinder is also installed at the bottom of the movable box. Guide rails compatible with the movable box are embedded on both sides of the single-layer multiple loading plates.

[0012] Furthermore, a sliding cavity is provided on the inner side of each vertical beam, a guide rod is fixed between the upper and lower inner walls of each sliding cavity, the cross beam is fixedly installed with the guide rod, the loading plate is movably installed with the guide rod, and a through hole is provided on the loading plate that is compatible with the guide rod.

[0013] Furthermore, a fixed bottom plate is provided at the bottom end of the vertical beam, and a material discharge space is formed between the horizontal supporting beam and the lowest loading plate and between two upper and lower adjacent loading plates, and the spacing between each upper and lower material discharge space is consistent.

[0014] Furthermore, each of the four corners of the upper end of the loading plate is fixed with a top support bar corresponding to the position of the cross support beam, the height of the top support bar is greater than the height of the storage tube, and the end wall of the cross support beam is provided with a through groove corresponding to the position of the top support bar and passing through it up and down, and the four corners of the bottom end of the base plate are provided with a top support groove corresponding to the position of the top support bar.

[0015] Furthermore, a pair of guide rails are embedded in the bottom end surface of the loading plate and extend downward, a notch is provided at the bottom end of the end of the crossbeam plate, and a through hole is provided at the notch.

[0016] Furthermore, the mobile bracket includes a mobile trolley located at the bottom, on which a plurality of support frames of the same frame structure are fixed, and a pair of left and right support frames are both equipped with support plates that can move up and down and are used to place the mobile box.

[0017] Furthermore, a top plate is fixed on the top of the support frame, and a pair of vertical screws are rotatably installed on the left and right ends of the mobile trolley. The upper ends of the pair of vertical screws respectively pass through the two support plates and are rotatably installed on the bottom end of the top plate. The vertical screws are connected with the threaded sleeves of the support plates, and a driving motor for synchronously rotating and driving the vertical screws is installed inside the mobile trolley.

[0018] Furthermore, the moving box is a rectangular structure with a width smaller than the width of the discharge space. The left and right sides of the moving box are both rotationally driven and equipped with walking wheels respectively located on two support plates and adapted to the guide rails. A braking control device for driving the walking wheels is installed inside the moving box.

[0019] Optionally, the clamping assembly includes an electric push rod slidably installed on the front and rear sides of the lower end of the moving box, a pair of electric push rod telescopic ends are fixed with clamping blocks, and sliding grooves for the sliding installation of the electric push rod are opened on both sides of the lower end of the moving box. A bidirectional screw with a thread passing through the end of the electric push rod is rotatably installed between the pair of sliding grooves, and a rotating motor for rotating the bidirectional screw is fixed to the outer end of the base plate.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) This scheme is an improvement on the traditional vertical shelves. Each layer of the loading board on each column of the vertically arranged single bracket is installed in an upward and downward movable manner as a whole, and is supported by a fixed horizontal support beam in the initial state. When loading and stacking, the mobile box in the loading and unloading unit is used to cooperate with the clamping assembly to clamp the storage tube, and then the mobile box is transported to the end of each layer of the loading board. The mobile box moves horizontally along a pair of longitudinally arranged guide rails to stack the storage tubes one by one from bottom to top and from inside to outside on the loading board. During the storage process, there is no need for a power mechanism to support the storage tube. When taking the storage tube at a specific position, it is only necessary to use a pair of telescopic cylinders and hooks to lift the two layers of the loading board at the position to be taken upward as a whole, thereby freeing up idle space for moving a storage tube. There is no need to lift all the loading boards upward, and there is no need to set a hydraulic rod at each loading board, which simplifies the structure and operation process.

[0022] (2) Top support bars corresponding to the positions of the cross beams are fixed at the four corners of the upper end of each loading board. The height of the top support bars is greater than the height of the storage tube. In the initial state, each layer of the loading board is supported on the cross beams. The fixed cross beams support the loading board. The height of the material discharge space is much greater than the height of the storage tube, and a certain height deviation is reserved between the bottom end of the previous loading board and the top end of the storage tube. On the one hand, it is convenient to place the storage tube. On the other hand, when taking materials, the loading board can be pushed upward layer by layer. After the top support bars are pushed upward, they rest in the top support groove of the loading board above it. At this time, the top of the storage tube located in the material discharge space does not contact the bottom end of the loading board, which protects the storage tube. The top support bars push the loading board above it upward to continue to move upward to a suitable height, so that only two layers of loading boards need to be pushed upward as a whole to create an extra idle space for moving a storage tube.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work shall fall within the scope of protection of the present invention.

[0036] Example 1: The present invention discloses a three-dimensional storage system for propylene carbonate processing raw materials. Figure 1-4 , including a storage unit and a loading and unloading unit. The storage unit includes a plurality of single-body brackets arranged in an array. The single-body bracket includes four vertical beams 1 forming a square structure and a plurality of groups of cross-joists 4 fixedly distributed on the vertical beams 1 at equal intervals in the vertical direction. Each group of cross-joists 4 is provided with a pair of cross-joists 4 located on the left and right sides of the single-body bracket. The pair of cross-joists 4 is respectively fixed on the left and right pairs of vertical beams 1. The upper end of each group of cross-joists 4 is provided with a loading plate 2 which is slidably mounted with the vertical beam 1 and is used to support the storage cylinder 18. The storage cylinder 18 is used to load and store propylene carbonate processing raw materials.

[0037] See also Figure 4 Each vertical beam 1 has a sliding cavity on its inner side, and a guide rod 101 is fixed between the upper and lower inner walls of each sliding cavity. The cross joist 4 is fixedly installed with the guide rod 101, and the loading plate 2 is movably installed through the guide rod 101. A through hole is opened on the loading plate 2 to match the guide rod 101, and the cross joist 4 supports the loading plate 2.

[0038] The bottom end of the vertical beam 1 is also provided with a fixed bottom plate 3. A discharge space is formed between the horizontal supporting beam 4 and the lowest loading plate 2, as well as between the upper and lower adjacent loading plates 2. The spacing between each upper and lower discharge space is consistent. The loading plate 2 can move upward along the guide rod 101. When the loading plate 2 is lifted upward, the height of a single discharge space can be expanded.

[0039] See also Figure 3 、 4The multiple loading plates 2 of a single layer of the vertically arranged single-unit racks in each row are fixedly connected by a crossbeam 6. Both the front and rear ends of the crossbeam 6 pass through the outer side of the loading plates 2 and are provided with through-holes 601. The bottom end of the crossbeam 6 is provided with a notch, and the through-holes 601 are provided at the notch. The multiple loading plates 2 of the same layer on each vertically arranged single-unit rack can move up and down synchronously as a whole.

[0040] The four corners of the upper end of each loading plate 2 are fixed with top support bars 201 corresponding to the position of the cross support beam 4. The height of the top support bar 201 is greater than the height of the storage cylinder 18, and the end wall of the cross support beam 4 is provided with a through groove corresponding to the position of the top support bar 201 and passing through up and down. The four corners of the bottom end of the bottom plate 3 are provided with top support grooves corresponding to the position of the top support bar 201. In the initial state, each layer of loading plate 2 is supported above the cross support beam 4, and the fixedly installed cross support beam 4 supports the loading plate 2. The discharge space between the upper and lower adjacent loading plates 2 is used to place the storage cylinder 18. The height of the discharge space is much greater than the height of the storage cylinder 18, and a certain deviation height is reserved between the bottom end of the upper loading plate 2 and the top end of the storage cylinder 18 to facilitate the placement of the storage cylinder 18.

[0041] See also Figure 1 、 2 , the tops of the single supports arranged transversely on the front and rear sides are both equipped with crossbeams and telescopic cylinders 7 that move horizontally based on the crossbeams, and the telescopic ends of the telescopic cylinders 7 are fixed with hooks 8 that match the through holes 601;

[0042] See also Figure 7 、 Figure 8 When taking materials, first use the cross beams on both sides to move the telescopic cylinder 7 to the horizontal position, then lower the hook 8 through the telescopic cylinder 7. After the hook 8 approaches the end of the cross beam 6, lift the hook 8 upward until the hook 8 passes through the through hole 601 to complete the fixation between the two, and then lift the loading plate 2 upward;

[0043] At this time, the top support bar 201 on the loading plate 2 moves upward synchronously. After the top support bar 201 is pushed upward, it rests in the top support groove of the loading plate 2. The top of the hook 8 located in the discharge space does not contact the bottom end of the bottom plate 3, which protects the hook 8 and continues to push up another loading plate 2. During the whole process, it is only necessary to use a pair of telescopic cylinders 7 and hooks 8 to lift the two layers of loading plates 2 at the material-taking position to a certain height as a whole. There is no need to lift all the loading plates 2 upward, and there is no need to set a hydraulic rod at each loading plate 2, which saves power output and simplifies the structure and operation process.

[0044] Example 2: Based on Example 1, this example optimizes the structure of the loading and unloading unit to facilitate the stacking and taking of the storage cylinder 18, as follows:

[0045] See also Figure 5 、 6 The loading and unloading unit includes a mobile bracket and a mobile box 13 located on the mobile bracket. A clamping assembly for fixing the storage cylinder 18 is also installed at the bottom end of the mobile box 13. Guide rails 5 adapted to the mobile box 13 are embedded on both sides of each carrier 2. The front and rear adjacent guide rails 5 are connected to each other. A pair of guide rails 5 are embedded in the bottom end surface of the carrier 2 and extend downward.

[0046] The mobile bracket includes a mobile trolley 9 at the bottom, and a plurality of support frames 10 of the same frame structure are fixed on the mobile trolley 9. A pair of left and right support frames 10 are installed with support plates 12 that can move up and down and are used to place a mobile box 13. A top plate is fixed on the top of the support frame 10. A pair of vertical screws 11 are rotatably installed on both ends of the mobile trolley 9. The upper ends of the pair of vertical screws 11 respectively pass through the two support plates 12 and are rotatably installed on the bottom end of the top plate. The vertical screws 11 are threadedly connected with the support plates 12, and a drive motor for synchronously rotating and driving the vertical screws 11 is installed inside the mobile trolley 9.

[0047] The moving box 13 is a rectangular structure with a width smaller than the width of the discharge space. The left and right sides of the moving box 13 are rotatably driven and installed with walking wheels 131 respectively located on the two support plates 12 and adapted to the guide rails 5. A braking control device for driving the walking wheels 131 is installed inside the moving box 13. This is a prior art to enable the moving box 13 to move independently. The clamping assembly includes an electric push rod 15 slidably installed on the front and rear sides of the lower end of the moving box 13. A pair of electric push rods 15 are fixed with clamping blocks 17 at the telescopic ends. Sliding grooves for the sliding installation of the electric push rod 15 are provided on both sides of the lower end of the moving box 13. A bidirectional screw 14 with a threaded end of the electric push rod 15 is rotatably installed between the pair of sliding grooves, and a rotating motor 16 for rotating the bidirectional screw 14 is fixed to the outer end of the base plate 3.

[0048] When stacking, the storage cylinder 18 is placed on the mobile trolley 9, and the storage cylinder 18 can body is fixed by the clamping assembly at the bottom of the mobile box 13. A pair of clamping blocks 17 can move left and right and up and down to facilitate the positioning and clamping of the storage cylinder 18. The total height of the mobile box 13 and the storage cylinder 18 after positioning is less than the height of the discharge space. The mobile box 13 moves to the single bracket to be placed in the storage unit through the mobile bracket, and the mobile box 13 is lifted to the appropriate position by relying on the support plate 12. The mobile box 13 is transported to the guide rail 5 of the loading plate 2, and the electric push rod 15 moves horizontally along the guide rail 5 above each layer of the discharge space to realize stacking of the storage cylinder 18 from the inside to the outside and from the bottom to the top;

[0049] See also Figure 7-10When taking out the storage cylinder 18 at a certain position, first use the cross beam plates 6 on the front and rear sides to move the telescopic cylinder 7 to the horizontal position at that position, and then lower the hook 8 through the telescopic cylinder 7. After the hook 8 is close to the end of the cross beam plate 6, the hook 8 is lifted upward until the hook 8 passes through the through hole 601 to complete the fixation between the two. Then, the loading plate 2 on the longitudinally arranged single bracket is lifted upward. At this time, the top support bar 201 on the loading plate 2 moves upward synchronously. After the top support bar 201 is pushed upward, it rests in the top support groove of the loading plate 2. The top of the storage cylinder 18 in the material discharge space does not contact the bottom of the loading plate 2, which protects the storage cylinder 18. The top support bar 201 rests on the top support groove in the loading plate 2 above it to continue to support it until it approaches the next loading plate 2 above. The entire lifting process only requires lifting two layers of loading plates 2 upward to create an extra idle space for moving a storage cylinder 18.

[0050] Then, the mobile bracket is used to transport the mobile box 13 to the outside of the port of the idle space. The mobile box 13 moves inward along the pair of electric push rods 15 until it moves to the top of the storage cylinder 18 to be taken. The pair of clamping blocks 17 are lowered, and then the pair of clamping blocks 17 are brought close to each other to clamp the can body of the storage cylinder 18. After clamping, the storage cylinder 18 is lifted upward to the idle space, and the storage cylinder 18 is moved horizontally outward to move the storage cylinder 18 to the mobile bracket. The storage cylinder 18 is lowered to the mobile trolley 9 to complete the taking and placing of the specific position of the storage cylinder 18. Finally, it is only necessary to lower the pair of telescopic cylinders 7 downward so that the upwardly lifted loading plate 2 can be returned to its initial position, and the positioning between the hook 8 and the crossbeam plate 6 is released;

[0051] When replenishing a specific position, the same operation is performed, that is, first lifting the two layers of the loading plate 2 upward to make an idle space, transferring the storage cylinders 18 to be stacked into the idle space using the moving box 13, and then lowering them to the specific position.

[0052] In summary, this solution improves the traditional vertical racking. The entire three-dimensional storage system consists of a storage unit and a loading and unloading unit. The storage unit is composed of multiple single-unit brackets arranged in an array. Each single-unit bracket is vertically mounted with multiple vertically movable loading plates 2. Under normal conditions, the loading plates 2 are supported on a pair of fixed cross beams 4.

[0053] During loading and stacking, the storage cylinder 18 is clamped by the clamping assembly on the loading and unloading unit, and the mobile box 13 and the storage cylinder 18 are transported to the single bracket to be placed in the storage unit by the mobile bracket. The mobile box 13 is lifted to a suitable position by relying on the support plate 12, and the mobile box 13 is transported to the guide rail 5 of the loading plate 2, and moves horizontally along the guide rail 5 above each layer of the discharge space to achieve stacking of multiple storage cylinders 18 from the inside to the outside and from the bottom to the top;

[0054] When it is necessary to take out the storage cylinder 18 at a certain position, the electric guide rails on the front and rear sides are first used to move the telescopic cylinder 7 to the horizontal position at that position, and then the hook 8 is lowered by the telescopic cylinder 7. After the hook 8 is close to the end of the crossbeam 6, the hook 8 is lifted upward until the hook 8 passes through the through hole 601 to complete the fixation between the two. Then, the single-layer multiple loading board 2 is lifted upward. At this time, the top support bar 201 on the loading board 2 moves upward synchronously, and the top support bar 201 pushes up and rests on the top of the loading board 2 above it. In the supporting groove, at this time, the top of the storage cylinder 18 located in the material discharge space does not contact the bottom of the loading plate 2, which protects the storage cylinder 18. By continuing to push up one more loading plate 2 to a suitable position, there is an extra idle space for moving one storage cylinder 18. In this process, it is only necessary to use a pair of telescopic cylinders 7 to lift the two layers of loading plates 2 at the material removal position as a whole upward, without lifting all the loading plates 2 upward, and without setting a hydraulic rod at each loading plate 2, which simplifies the structure and operation process.

[0055] After freeing up idle space for moving a storage cylinder 18, the mobile bracket is used to transport the mobile box 13 to the exit at the end of the idle space. The mobile box 13 moves horizontally to the material-removing position by relying on the guide rail 5 at the bottom end of the loading plate 2, and drives the electric push rod 15 downward to clamp the storage cylinder 18 by relying on a pair of clamping blocks 17. Then, it moves along the idle space to the exit, and the storage cylinder 18 located on the inside of the shelf can be taken out.

[0056] The above are only preferred specific implementation methods of the present invention; however, the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved conception of the present invention shall be covered within the protection scope of the present invention.
