[0001] This utility model relates to the field of warehouse racking technology for refrigerated container stacker cranes, and in particular to a racking structure for refrigerated container stacker crane warehouses. Background Technology

[0002] The racking structure of a refrigerated container stacker warehouse is a high-density storage system specifically designed for the automated storage and retrieval of refrigerated containers (typically the size of standard shipping containers). Existing refrigerated container stacker warehouse racking systems have the following problems:

[0003] 1) Low space utilization: The stacker crane track is designed separately from the rack, which occupies extra space, and the track level is difficult to synchronize with the rack.

[0004] 2) Unsupported container side walls: Long-term stacking may cause deformation of the container side walls, affecting sealing and insulation performance. Therefore, we propose a rack structure for refrigerated container stacker warehouses. Utility Model Content

[0005] In view of the problems of low space utilization and lack of support on the side walls of existing refrigerated container warehouse racks, this utility model is proposed.

[0008] The portal frame is constructed by welding vertical stainless steel square tubes and top horizontal stainless steel square tubes. The horizontal connector is a stainless steel angle steel that horizontally connects to the vertical stainless steel square tubes on adjacent portal frames. The cargo-bearing component is a rack beam, with both ends fixed to the vertical stainless steel square tubes on the portal frame. The track fixing components include a stacker crane ground track beam and a ceiling track beam, which are fixed to the bottom and top of the portal frame, respectively. The side wall support is an extended horizontal brace that extends horizontally to and abuts against the side wall of the refrigerated container. The bottom of the portal frame is provided with feet, which are fixedly connected to the air ducts on the top of the refrigerated container by adjusting bolts.

[0012] As a technical solution for the rack structure of a refrigerated container stacker warehouse described in this utility model, the extended cross brace is a telescopic sleeve structure with rubber buffer pads at both ends, and elastically contacts the side wall of the container.

[0013] As a technical solution for the rack structure of a refrigerated container stacker warehouse described in this utility model, the base is a rectangular steel plate with an elongated hole, and the elongated hole is fixed to the air duct by adjusting bolts to compensate for the gap.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. This utility model adopts an integrated shelf and track design to reduce space occupation. Combined with the pre-embedded positioning pin holes and adjustable feet, it can realize synchronous calibration of the track and shelf to reduce maintenance costs.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1-3 A racking structure for a refrigerated container stacker warehouse is provided. This racking structure for a refrigerated container stacker warehouse includes at least two sets of parallel portal frames, transverse connectors, cargo bearing components, rail fixing components, and side wall supports.

[0025] The portal frame is constructed by welding vertical stainless steel square tubes 1 and top horizontal stainless steel square tubes 3. Horizontal connectors are stainless steel angle bars 4, which horizontally connect to the vertical stainless steel square tubes 1 on adjacent portal frames. Cargo load-bearing components are rack beams 2, fixed at both ends to the vertical stainless steel square tubes 1 on the portal frame. Track fixing components include stacker crane ground rail beams 5 and ceiling rail beams 6, fixed to the bottom and top of the portal frame respectively. Side wall supports are extended horizontal braces 7, extending horizontally to and abutting against the side wall of the refrigerated container. The bottom of the portal frame is equipped with feet 8. Foot 8 is fixedly connected to the air duct on the top of the refrigerated container by adjusting bolts. In application, the integrated design of the portal frame and track fixing components (stacker ground rail beam 5 and ceiling rail beam 6) reduces the space occupied by the stacker crane track and the rack, improving space utilization. At the same time, the side wall support component (extended cross brace 7) abuts against the side wall of the refrigerated container, enhancing the support for the container side wall and preventing deformation caused by long-term stacking. Foot 8 is connected to the air duct by adjusting bolts to achieve stable fixation of the rack and the top of the container, preventing rack displacement.

[0026] Reference Figure 2 and Figure 3 The connection between the vertical stainless steel square tube 1 and the top horizontal stainless steel square tube 3 is reinforced by welding with reinforcing ribs. In application, the welding of reinforcing ribs to the connection between the vertical and top horizontal stainless steel square tubes 3 improves the overall rigidity of the portal frame and ensures the stability of the track installation.

[0027] Reference Figure 2 and Figure 3The surface of the rack beam 2 is covered with anti-slip corrugated steel plate, and the corrugation direction of the anti-slip corrugated steel plate is perpendicular to the length direction of the rack beam 2. In application, the anti-slip corrugated steel plate can increase the friction between the goods and the rack beam 2. Combined with the corrugation direction design, it reduces the risk of goods slipping during the operation of the stacker crane.

[0028] Reference Figure 2 and Figure 3 The top surfaces of the stacker crane's ground rail beam 5 and overhead rail beam 6 are provided with rail mounting grooves, and positioning pin holes are pre-embedded in the grooves. In application, the rail mounting grooves and pre-embedded positioning pin holes simplify the rail installation process, improve the efficiency of rail level calibration, and ensure the operating accuracy of the stacker crane.

[0029] Reference Figure 2 and Figure 3 The extended cross brace 7 is a telescopic sleeve structure with rubber buffer pads at both ends, which elastically contact the container side wall. In application, the telescopic sleeve structure of the extended cross brace 7 can be adapted to different refrigerated container sizes. The rubber buffer pads reduce the impact force of the rack contacting the side wall and protect the container's sealing.

[0030] Reference Figure 2 and Figure 3 The foot 8 is a rectangular steel plate with an elongated hole. The elongated hole is fixed to the air duct by adjusting bolts to compensate for the gap. In application, the design of the elongated hole of the foot 8 can be used to compensate for the gap by adjusting bolts, which solves the problem of installation error of the air duct on the top of the container and improves the adaptability of the rack installation.

[0031] The installation process of the shelf structure of this utility model is as follows: Basic positioning: Measure the internal dimensions of the refrigerated container, mark the position of the shelf uprights, ensure that they are aligned with the air duct, then install the feet 8, and initially fix them to the air duct through the elongated hole adjusting bolts;

[0032] Frame assembly: Welding gate frame unit: Weld vertical stainless steel square tube 1 to top horizontal stainless steel square tube 3, and weld reinforcing ribs at the connection.

[0033] Horizontal connection: Stainless steel angle steel 4 is used to horizontally weld the vertical stainless steel square tube 1 of the adjacent frame to form an integral skeleton;

[0034] Functional component installation: Shelf beam 2 fixing: Weld shelf beam 2 to the designed height of vertical stainless steel square tube 1, and lay anti-slip corrugated steel plate, with the corrugation direction perpendicular to the track;

[0035] Track installation: The pre-embedded grooves of the stacker crane ground rail beam 5 and overhead rail beam 6 are leveled by locating pin holes;

[0036] Side wall support adjustment: The telescopic adjustment extends the cross brace to fit snugly against the container side wall. The compression of the rubber buffer pad is controlled at 3-5mm to achieve elastic contact. At the same time, the verticality and horizontality of the rack are retested, and the anchor bolts are finely adjusted to eliminate deviations.

[0037] Acceptance testing: The stacker crane is run unloaded to test the track flatness, and simulated goods are loaded at the same time to check the deformation of the rack and the stability of the side wall support.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
