[0040] This invention provides a shipborne core storage facility, an automated core storage system, and its installation method. This system is being used on a ship for the first time, involving numerous new pieces of equipment. The original installation process was quite complex. By leveraging the unique characteristics of each piece of equipment, the installation process has been streamlined to 16 steps. The tools used during installation are all common and reliable, such as hoists, pulleys, laser pointers, plumb bobs, and measuring tapes. Precision control and adjustment are closely aligned with the operating routes of the stacker crane and shuttle car. Therefore, this installation process is simple, clear, easy to operate, and allows for precise precision control.

[0041] This invention, based on the structural characteristics of the core storage facility, equipment volume, equipment entry routes, and hoisting tools, designs the racking system in sections, and for large-volume equipment, designs it in separate sections, while also planning a reasonable sequence for equipment and components to enter the storage compartment. This invention adds a base assembly, which allows for adjustment of the overall racking precision by adjusting the adjustable bolts, effectively reducing the impact of poor deck precision on racking accuracy.

[0042] In this invention, the installation process of the core storage room and the automated core storage system involves fewer steps and fewer auxiliary tools. Moreover, a reliable support system is formed in the early stage of installation through the fixed connectors of the shelves and the fixed connectors of the storage panels before the installation of other parts, which makes the installation process highly reliable.

Detailed Implementation

[0058] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0059] The technical solution of the present invention provides a shipborne core storage facility, which is set in a sealed compartment between the double bottom and the lower deck of the main hull. The core storage facility is a standard cuboid warehouse, including a cold storage floor, cold storage wall panels, cold storage roof panel, cold storage panel fixing accessories, cold storage door, air cooler and pipelines.

[0060] When using the shipborne core storage facility provided by this invention, the cores are transported down from the elevator by a transfer trolley and pushed into the core storage facility. The system then enables automatic entry, exit, and positioning storage of the cores. Finally, the cores are retrieved from the storage facility via an elevator. The specific layout is as follows: Figures 1 to 2As shown. The core storage room is located in a sealed compartment between the double bottom and lower deck of the main hull, designed to maintain a temperature of +4 degrees Celsius. It contains several high-temperature air coolers and their piping, with dimensions of approximately 22m x 10m x 4m. The core storage room consists of a cold storage floor, cold storage walls, a cold storage roof, cold storage panel fixing accessories, cold storage doors, air coolers, and piping. The cold storage panels are prefabricated polyurethane foam core panels, 120mm thick, with an internal 1mm thick 304 stainless steel plate and an external 0.7mm thick galvanized steel plate or color steel plate. Reinforcing components are pre-embedded inside the cold storage floor, walls, and roof according to the shelving layout. The cold storage doors include two sets of electric sliding doors 10 and one set of hinged cold storage doors 9, all made of double-sided stainless steel plates with rigid polyurethane foam insulation. The electric sliding door 10 is installed on the cold storage wall panels on both sides of the elevator, and the hinged cold storage door 9 is installed on the cold storage wall panel opposite to the electric sliding door 10. An air curtain 11 is installed above the cold storage door; when the sliding door is opened, the air curtain 11 operates to prevent cold air from escaping from the cold storage. Figures 2 to 4 As shown, pre-embedded reinforcing components are arranged inside the cold storage floor, cold storage wall panels, and cold storage roof according to the automated core storage system.

[0061] In addition to providing a shipborne core storage facility, the present invention further provides an automated core storage system. The system is installed in the shipborne core storage facility to realize the automatic entry and exit of cores and their location storage. The system includes a core storage rack 2, a stacker crane 3, a shuttle 14, a bidirectional telescopic fork 5, an assisted picking device 7, a connecting platform 6, core pallets 15, and a server and control cabinet 16.

[0062] Among them, the core storage rack 2 is a high-density warehouse rack. Core storage rack 2 is equipped with pallet stations and a travel track for the shuttle 14, and can achieve self-locking with the core pallets 15. Core storage rack 2 is arranged around the stacker crane 3. Core storage rack 2 is made of Q355D material, and its main structure includes welded base components, uprights, tracks, beams, diagonal braces, and fixing connectors. The base components adopt a special node design, such as... Figure 5 As shown, it mainly includes shelf uprights 17, load-bearing panels 18, steel plate covers 19, steel plate bases 20, bolts 21 and adjusting nuts 22, with sleepers 23 in the middle. The steel plate covers and steel plate bases are disconnected, which can ensure load-bearing capacity while isolating cold bridges.

[0063] The stacker crane 3 is equipped with a stacker crane track 4 and a shuttle car 14. The shuttle car 14 can move up and down along the height direction on the stacker crane 3. The stacker crane track 4 is adapted to the track of the core storage rack 2. The shuttle car 14 can move on the track of each rack by adjusting the height of the shuttle car 14.

[0064] The shuttle 14 is equipped with a core tray 15.

[0065] The bidirectional telescopic fork 5 is located near the stacker crane 3 and the elevator. The frame of the bidirectional telescopic fork 5 is equipped with a picking fork that can extend and retract left and right, which can realize the transfer of the core pallet 15 from the warehouse to a fixed position in the elevator.

[0066] The assisted picking device 7 is installed above the core storage shelf 2 on the side of the elevator inside the cold storage.

[0067] The connecting platform 6 is located between the elevator pit and the core storage.

[0068] The server and control cabinet 16 are installed in the core storage room and are connected to each device via wired or wireless means to control the operation of each device.

[0069] like Figure 6 As shown, in one embodiment of the present invention, the stacker crane 3 is an aisle type, including a stacker crane body 24, a ceiling rail 25, a ground rail 26, and an electrical control cabinet assembly. The ceiling rail 25 and the ground rail 26 are fixedly connected to the cold storage floor and the cold storage roof, respectively. A slide rail is provided on the stacker crane body 24, and a shuttle car 14 can be mounted on the stacker crane body 24. The shuttle car 14 can carry a core tray 15, achieving displacement along the rack track direction, and can park on the stacker crane 3. Displacement in height and along the stacker crane track direction is achieved through the stacker crane 3, and the core tray is transferred to the elevator via the bidirectional telescopic forks 5. In this embodiment, the structure of the shuttle car 14 is as follows: Figure 7 As shown, the structure of the bidirectional telescopic fork 5 is as follows: Figure 8 As shown.

[0070] like Figure 9 As shown, in one embodiment of the present invention, a structure for a connecting platform 6 is provided, the height of which is equal to the height difference between the elevator floor and the core storage floor caused by the elevator pit.

[0071] like Figure 10 As shown, in one embodiment of the present invention, the assisted picking device 7 includes a track frame and an electric hoist. With the assisted picking device 7, the core box can be easily and conveniently moved by man.

[0072] The present invention also provides an installation method for the above-mentioned core repository and automated core storage system, the specific steps of which are as follows:

[0073] Step 1: Pre-installation of core equipment in the factory before entering the cabin:

[0074] To ensure a smooth installation process and shorten the installation cycle, core equipment with large volume and complex structure, such as stacker cranes and shelves, needs to be pre-installed before leaving the factory to check the assemblability and integrity of the equipment. Where welding is required, spot welding can be used for fixation.

[0075] Step 2, Construction Condition Inspection:

[0076] (1) The construction of the ship's hull structure around the cold storage has been completed and passed inspection;

[0077] (2) Check whether the structural dimensions of the area where the core storage is located meet the requirements and whether the deck accuracy requirements meet the requirements. The allowable deviations should meet the following requirements: allowable deviation in length and width of the core storage body: ±15mm, allowable deviation in deck flatness: ±15mm; and within the load-bearing area of ​​the rack, considering the dynamics of the hull, the uneven settlement deformation of the deck under full load should be less than 5mm.

[0078] (3) Check whether the relevant water and electricity interfaces, fire protection, lighting and other facilities in the area have been equipped;

[0079] (4) Check whether the relevant drawings and tools are ready and whether the personnel who have been trained and qualified in professional knowledge and safety production knowledge have been on duty.

[0080] Step 3, Marking and Positioning:

[0081] Because the stacker crane is an aisle-type system, and the entire racking system is arranged around it, the positions of all equipment are determined using the center line of the stacker crane's track as a reference point. Then, each piece of equipment is positioned according to the installation drawings, including the locations of equipment feet and fixed connections on the deck, bulkheads, and ceiling. Figure 11 As shown.

[0082] Step 4: Pre-assembled parts are installed and welded in the compartment.

[0083] The pre-assembled components mainly include slots, fixing brackets, and supports for the core storage cold storage panels that are fixed to the hull, as well as connecting parts and supports for the racks that are also fixed to the hull. To facilitate the later fixing of the cold storage panels and racks, they need to be pre-welded and fixed to the hull structure in advance, forming a complete installation frame for the cold storage panels and a support system for the overall rack structure.

[0084] Step 5: Welding of the equipment's foundation feet assembly into the compartment.

[0085] The anchors for fixing the equipment to the deck in this system employ a special node design, consisting of a steel plate base, steel plate cover, intermediate sleepers, bolts, adjusting nuts, lower flanges of the rack uprights, and load-bearing panels. During installation, the steel plate base is first spot-welded in place, then the sleepers are placed. Next, the lower flanges of the rack uprights, equipped with bolts and adjusting nuts, are welded to the steel plate cover. These components are then installed on the sleepers, and finally, the load-bearing panels are spot-welded to their corresponding positions. Since the load-bearing panels and bolts share the weight of the rack, final welding is completed after precision adjustments. Finally, after all anchors are pre-installed and their overall precision is verified, welding between the anchors and the deck is performed. Figure 11 As shown.

[0086] Step 6: Installation of core storage tank floor and wall panels:

[0087] After the cold storage panels and shelving fixing connectors and equipment feet are installed, the cold storage floor and side panels can be installed. The cold storage floor needs to have holes drilled according to the location and size of the feet. Then, the cold storage floor is fitted onto the equipment feet, and the gaps between the feet and the holes in the cold storage floor are filled with polyurethane foam. The cold storage floor is assembled sequentially from the doorway inwards. If deviations or unevenness are found during the installation of the panels, adjustments should be made promptly. After the cold storage floor is installed, the stainless steel surface layer is installed. The installation of the cold storage wall panels is similar to that of the cold storage floor. Holes for the shelving connectors are drilled in the cold storage panels beforehand, and the connectors are fitted onto the panels before installation. Figure 12 As shown.

[0088] Step 7: Stacker crane installation in the cabin and track accuracy adjustment:

[0089] (1) The stacker crane includes the stacker crane body, ground rails and overhead rails. The specific precision requirements for the ground rails and overhead rails are as follows:

[0090] 1) The straightness tolerance of the ground track is:

[0091] When the measured length equals the total length of the track, the deviation is ±3.0 mm.

[0092] Measurement length = wheelbase deviation of the stacker crane in the tunnel: ±1.5mm;

[0093] The contact area of ​​the track head of different sizes should be ground flat, and the flatness of the joint should be less than or equal to 0.5mm in the range of measurement lengths of 200mm or more.

[0094] 2) The flatness tolerance of the ground track is:

[0095] Deviation when measuring length < 100mm: ±2.0mm

[0096] Deviation when measuring length ≥ 100mm: ±3.0mm

[0097] When measuring length = wheelbase deviation of the stacker crane in the aisle: ±0.5mm

[0098] The contact area of ​​the track head of different sizes must be ground flat; the flatness of the track and its joints must be less than or equal to 0.1mm in the range of measured dimensions exceeding 100mm in length.

[0099] 3) The tolerance of the average value of the longitudinal axis of the overhead rail relative to the centerline of the rack uprights along the aisle is ±5mm when the measurement length exceeds 50m.

[0100] 4) The maximum deviation of the vertical distance between the upper and lower tracks is ±10mm;

[0101] 5) Horizontal misalignment (overlap) of the vertical and horizontal tracks ≤ 5mm;

[0102] (2) Ground rail installation: First, arrange the ground rails in sequence on the pre-installed anchor assemblies. Each ground rail should be aligned with the ground rail edge line and pre-tightened with the ground rail clamping plate. Adjust the side and top surfaces of the ground rails according to the accuracy requirements. When adjusting the side surfaces of the ground rails, use a sledgehammer or jacks to tap the ground rails at intervals to straighten and align them. The ground rail clamping plate must be tightened after alignment. During the straightening process, the side surfaces of the ground rails should be parallel to the marking line. Use a steel ruler or laser theodolite to check the straightness of the ground rails. Use a level to re-measure the levelness and flatness of the top surface of the ground rails every 500mm along the entire length of the ground rails. For any test points that do not meet the requirements, the ground rails should be readjusted. Finally, weld the ground rails to the anchor assemblies.

[0103] (3) Installation of overhead rails: Arrange the overhead rails of the stacker crane in sequence in the roadway; hoist the single overhead rail to the overhead rail connector seat, adjust the overhead rail and connect it with bolts; use a theodolite or plumb bob to align the center lines of the overhead rail and the ground rail to be coplanar, and ensure the symmetry of the overhead rail and the roadway; measure and align the straightness and parallelism of the ground rail and the overhead rail, and adjust if they are not parallel. After adjustment and alignment, tighten with bolts and ensure the distance between the overhead rail and the ground rail.

[0104] (4) Stacker crane body installation: The stacker crane body is large and needs to be installed in sections. The installation method is to use a split hoisting method. Use a hand hoist or other lifting tools to connect to the ground rail and overhead rail in sequence, and then assemble the stacker crane control box and other electrical equipment to complete the installation.

[0105] Step 8: Pre-installation and forming of the rack structure in the storage compartment:

[0106] In addition to the foundation assemblies installed in step 2.5, the rack structure also includes rack uprights, rack longitudinal and transverse beams, rack diagonal braces, rack rails, and fixing connectors. To reduce the amount of welding and installation work on board, welding is carried out in the factory as much as possible. Several rack panels are formed according to the cabin access process and lifting tools, with each panel containing two rack uprights and diagonal braces and transverse beams between them. During installation, the rack panels are first pre-installed by spot welding to the corresponding foundation assemblies in sequence. The rack panels are then erected manually (using pulleys, hoists, etc.) according to their height and weight. Then, using the installed rack panels as a reference, the rear racks are installed, and the transverse beams, rack rails, and fixing connectors between the panels are connected to form a stable structure, thus initially forming the overall rack.

[0107] Step 9: Adjust the shelf precision.

[0108] The precision requirements for shelving mainly involve controlling the overall precision of the shelving and the precision of the shelving tracks. This is crucial for ensuring that shuttle vehicles can smoothly enter and exit the shelving, so the precision requirements for shelving are relatively high. The specific precision requirements are as follows:

[0109] (1) The maximum deviation of the column height (along the ship's width) in each row of shelves is ±5mm;

[0110] (2) The limit deviation of the spacing between the uprights in the same rack aisle is ±5mm;

[0111] (3) The center-to-center distance between the bottom of adjacent shelf uprights deviates by ±3mm;

[0112] (4) The verticality tolerance of each row of racks on both sides of the stacker crane track is ≤15mm;

[0113] (5) The positional deviation of the racks in the same row on both sides of the stacker crane track is ≤5mm;

[0114] (6) Height deviation of beams on the same floor ±5mm;

[0115] (7) For crossbeams on the same shelf and in the same layer, the height of the crossbeam closest to the stacker crane should not be lower than that of other crossbeams, and the height difference should be ≤3mm; (to minimize the stacker crane's climbing position).

[0116] (8) The bending deviation of each row of racks (along the width of the ship) is ≤15mm;

[0117] (9) The bending deviation of each row of shelves (along the length of the ship) is ≤15mm;

[0118] (10) The dimensional deviation from the center line of the stacker crane track to the shelves on both sides is ±2mm;

[0119] During precision adjustment, the overall dimensions of the shelving are remeasured according to the above precision requirements. Preliminary adjustments to the shelving's height, verticality, and level are made using the shelving's anchor bolts and connecting bolts. Any other accessories are installed one by one to ensure all data meets the standards. The testing instruments used include a laser pointer, plumb bob, and measuring tape. During shelving installation, the overall horizontal and vertical adjustments are simultaneously performed until the shelving meets the standards.

[0120] After the accuracy is adjusted and accepted, the welding of the load-bearing panels of the shelving base is completed as required, and all shelving connecting bolts are finally tightened.

[0121] Step 10: Installation of the core storage top plate into the chamber:

[0122] At this point, the shelving is fully formed and the relevant precision has been adjusted, allowing for the sealing of the core storage top panel. The installation of the cold storage top panel is similar to that of the cold storage wall panels and floor. Holes for the shelving top connectors are pre-drilled in the cold storage panels. After inserting the connectors, the top of the shelving is connected to the connectors welded to the ceiling using bolts. This process is repeated to complete the installation of the cold storage top panel, resulting in the overall formation of the cold storage unit. Figure 12 As shown.

[0123] Step 11: Installation of equipment such as bi-directional telescopic forks:

[0124] Install the bi-directional telescopic forks, cold storage external connection platform, assisted picking device, air cooler, and piping according to the drawings. Since the bi-directional telescopic forks and cold storage external connection platform are located outside the cold storage, the cold bridge effect is not considered; they can be directly welded and installed after establishing the reference points. The assisted picking device should be fixed to the top of the rack as per the drawings, ensuring the electric hoist track is level.

[0125] Step 12, Server rack installation:

[0126] Server racks, control cabinets, etc. are installed on the connection platform. The control cabinet is installed and wired according to the drawings. If conditions permit, preliminary debugging and testing can be carried out.

[0127] Step 13: Installation of cold storage doors and air curtains:

[0128] At this point, the equipment inside the cold storage was mostly installed, with door openings and frames left. After a double-check, the three cold storage doors were installed, and the door gaps were filled with polyurethane foam before stainless steel finishing. Wiring was required after the two electric sliding doors were installed. The air curtain was installed and wired according to the drawings, 200mm from the top edge of the door.

[0129] Step 14, Control System Installation and Wiring:
