Description

Technical Field

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

[0002] Propylene carbonate is an important chemical raw material, which is widely used in battery electrolyte, solvent, 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 a storage method thereof, 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 closely as possible. Then, the height of each layer of the shelf above 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, a new space is formed above the goods at the specific position by controlling the movement of each layer of the shelf, so that the goods at the specific position can be taken out.

[0005] This invention solves the problem that the original shelves need to design aisles when picking and placing goods at specific positions. However, a first hydraulic rod needs to be set at the placement plate of each layer. When taking out a single item, multiple first hydraulic cylinders need to work synchronously. There are too many power-driven mechanical structures and the operation is relatively cumbersome.

[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 warehousing 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] Therefore, we propose a three-dimensional storage system for propylene carbonate processing raw materials to address the above problems. Summary of the invention

The tops of the transversely arranged single-body brackets on the front and rear sides are both equipped with cross beam plates and telescopic cylinders based on the transverse horizontal movement of the cross beam plates, and the telescopic ends of the telescopic cylinders are fixed with hooks adapted to the through holes;

[0011] The loading and unloading unit includes a mobile bracket and a mobile box located on the mobile bracket. A clamping assembly for fixing the storage cylinder is also installed at the bottom of the mobile box. Guide rails compatible with the mobile box are embedded and installed on the left and right 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 on the guide rod, the loading plate is movably installed on the guide rod, and a through hole matching the guide rod is provided on the loading plate.

[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 support 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 loading plates is fixed with top support bars corresponding to the position of the cross support beam at the four upper corners, the height of the top support bars is greater than the height of the storage tube, and a through groove corresponding to the position of the top support bar and passing through the end wall of the cross support beam is provided, and top support grooves corresponding to the position of the top support bar are provided at the four lower corners of the bottom plate.

[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 that also form a square frame structure are fixed, and a left and right pair of 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 both ends of the left and right ends of the mobile trolley. The upper ends of the pair of vertical screws respectively penetrate 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 rotatably driven to install moving boxes respectively located on two support plates and adapted to the guide rails. A braking control device for driving the moving box 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, both sides of the lower end of the moving box are provided with sliding grooves for the sliding installation of the electric push rod, a bidirectional screw rod which is threaded through the end of the electric push rod is rotatably installed between the pair of sliding grooves, and a rotating motor for rotationally driving the bidirectional screw rod 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 shelf. Each layer of the loading board on each column of the single bracket arranged longitudinally is installed in an integral manner and is supported by a fixedly installed cross beam in the initial state. When loading and stacking, the mobile box in the loading and unloading unit cooperates with the clamping assembly to clamp the storage cylinder, 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 guide rails arranged longitudinally to stack the storage cylinders one by one on the loading board from bottom to top and from inside to outside. During the storage process, there is no need for a power mechanism to support the storage cylinder. When taking the storage cylinder 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 cylinder. 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, thereby simplifying the structure and operation procedures.

[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, and 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 top of the cross beam, and the fixed cross beam supports the loading board. The height of the material discharge space is much greater than the height of the storage tube, and a certain deviation height 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 an appropriate height, so that only two layers of loading boards need to be pushed upward as a whole to create idle space for moving an extra storage tube.

[0035] The following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 without creative work based on the embodiments of the present invention belong to 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, see 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 frame structure and a plurality of groups of horizontal joists 4 fixedly distributed on the vertical beams 1 at equal intervals in the vertical direction, each group of horizontal joists 4 is provided with a pair of vertical beams 1 located on the left and right sides of the single-body bracket, and each pair of horizontal joists 4 is respectively fixed on the left and right pairs of vertical beams 1, and each group of horizontal joists 4 is provided with a loading plate 2 slidably mounted with the vertical beams 1 and used to support the storage cylinder 18 at the upper end, and the storage cylinder 18 is used to load and store the propylene carbonate processing raw materials;

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

[0038] A fixed bottom plate 3 is also provided at the bottom end of the vertical beam 1. A material discharge space is formed between the horizontal support beam 4 and the lowest loading plate 2 and between two adjacent loading plates 2. The spacing between each upper and lower material 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 material discharge space can be expanded.

[0039] See also Figure 3 , 4The single-layer multiple loading plates 2 of each column of the vertically arranged single-body brackets are fixedly connected by a crossbeam plate 6. Both the front and rear ends of the crossbeam plate 6 penetrate the outer side of the loading plate 2 and are provided with a through hole 601. The bottom end of the crossbeam plate 6 is provided with a notch, and the through hole 601 is provided at the notch. The multiple loading plates 2 of the same layer on each column of the vertically arranged single-body brackets can move up and down synchronously as a whole;

[0040] Top support bars 201 corresponding to the position of the cross support beam 4 are fixed to the four upper corners of each loading plate 2, the height of the top support bar 201 is greater than the height of the storage cylinder 18, and a through groove corresponding to the position of the top support bar 201 and penetrating up and down is opened on the end wall of the cross support beam 4, and top support grooves corresponding to the position of the top support bar 201 are opened at the four bottom corners of the bottom end of the bottom plate 3. In the initial state, the loading plate 2 of each layer is supported on the top of 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 brackets arranged transversely on the front and rear sides are both installed with cross beams and telescopic cylinders 7 based on the transverse horizontal movement of the cross beams, and the telescopic ends of the telescopic cylinders 7 are fixed with hooks 8 adapted to the through holes 601;

[0042] See also Figure 7 , Figure 8 When taking materials, first use the cross beam plates on both sides to move the telescopic cylinder 7 to the horizontal position there, then lower the hook 8 through the telescopic cylinder 7, and after the hook 8 is close to the end of the cross beam plate 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 being pushed upward, the top support bar 201 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 of the bottom plate 3, which protects the hook 8 and continues to push up another loading plate 2. During the whole process, only a pair of telescopic cylinders 7 and hooks 8 need to be used to lift the two layers of loading plates 2 at the material-taking position upward 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 procedures.

[0044] Embodiment 2: Based on Embodiment 1, this embodiment optimizes the structure of the loading and unloading unit to facilitate the stacking and taking of the storage tube 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 tube 18 is also installed at the bottom of the mobile box 13. Guide rails 5 adapted to the mobile box 13 are embedded on the left and right sides of each carrier 2. The guide rails 5 adjacent to each other 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 located at the bottom, and a plurality of support frames 10 that also constitute a square frame structure are fixed on the mobile trolley 9. A pair of left and right support frames 10 are each installed with a support plate 12 that can move up and down and is used to place a mobile box 13. A top plate is fixed to the top of the support frame 10. A pair of vertical screws 11 are rotatably installed at both ends of the mobile trolley 9. The upper ends of the pair of vertical screws 11 respectively penetrate the two support plates 12 and are rotatably installed at the bottom end of the top plate. The vertical screw 11 is threadedly connected with the support plate 12, and a driving motor for synchronously rotating and driving the vertical screw 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 moving box 13 is rotatably driven on both sides thereof, and moving boxes 131 are respectively located on two support plates 12 and matched with the guide rails 5. A brake control device for driving the moving box 131 is installed inside the moving box 13. This is a prior art, so as to realize that the moving box 13 can move autonomously. 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 clamping blocks 17 are fixed at the telescopic ends of the electric push rods 15. Sliding grooves for the sliding installation of the electric push rods 15 are provided on both sides of the lower end of the moving box 13. A bidirectional screw 14 threadedly penetrated through the end of the electric push rod 15 is rotatably installed between the pair of sliding grooves, and a rotating motor 16 for rotationally driving the bidirectional screw 14 is fixed at the outer end of the bottom 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 a suitable position by 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 the 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 a 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 location, 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, 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 board 2 on the longitudinally arranged single bracket upward. At this time, the top support bar 201 on the loading board 2 moves upward synchronously, and the top support bar 201 pushes upward and rests in the top support groove of the loading board 2. The top of the storage cylinder 18 located in the discharge space does not contact the bottom of the loading board 2, which protects the storage cylinder 18. The top support bar 201 rests on the top support groove in the loading board 2 above it to continue to support it until it approaches the next loading board 2. The entire lifting process only requires lifting two layers of loading boards 2 upward to create an extra idle space for moving a storage cylinder 18.

[0050] Then, the mobile box 13 is transported to the outside of the port of the idle space by using the mobile bracket, and the mobile box 13 moves inward along the pair of electric push rods 15 until it moves to the top of the storage tube 18 to be taken, and a pair of clamping blocks 17 are lowered, and then the pair of clamping blocks 17 are brought close to each other to clamp the body of the storage tube 18, and after clamping, the storage tube 18 is lifted upward to the idle space, and the storage tube 18 is moved horizontally outward to move the storage tube 18 to the mobile bracket, and the storage tube 18 is lowered to the mobile trolley 9 to complete the taking and placing of the specific position of the storage tube 18, and finally, only a pair of telescopic cylinders 7 need to be lowered downward to make the upwardly lifted loading plate 2 return to the 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, firstly lifting the two layers of the carrier plate 2 upward to vacate an idle space, transferring the storage cylinders 18 to be stacked into the idle space by the moving box 13, and then lowering them to the specific position.

[0052] In summary, this solution improves the traditional vertical shelves. The entire three-dimensional storage system consists of a storage unit and a loading and unloading unit. The storage unit is composed of a plurality of single brackets arranged in an array. Each single bracket is vertically mounted with a plurality of loading boards 2 that can move up and down. The loading boards 2 are supported on a pair of fixed cross beams 4 in a normal state.

[0053] When 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, and the mobile box 13 is lifted to a suitable position by the support plate 12, and the mobile box 13 is transported to the guide rail 5 of the loading plate 2, and horizontally moved along the guide rail 5 above each layer of the material discharge space, so that multiple storage cylinders 18 can be stacked 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 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, and 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 upward and then abuts against 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 carrier plate 2, which protects the storage cylinder 18, and continues to support one more carrier plate 2 upward to a suitable position, so that 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 oil cylinders 7 to lift the two layers of carrier plates 2 at the material-taking position upward as a whole, without lifting all the carrier plates 2 upward, and without setting a hydraulic rod at each carrier plate 2, which simplifies the structure and operation process;

[0055] After an idle space for moving a storage cylinder 18 is vacated, the mobile box 13 is transported to the exit at the end of the idle space by using a mobile bracket. 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 the electric push rod 15 is driven downward to clamp the storage cylinder 18 by relying on a pair of clamping blocks 17. Then, the mobile box 13 moves along the idle space to the exit, and the storage cylinder 18 located on the inner side of the shelf can be taken out.

[0056] The above are only preferred specific implementation modes 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 concept of the present invention shall be covered within the protection scope of the present invention.
