Description

Technical Field

[0001] This invention belongs to the field of container transportation technology, and specifically relates to a coiled steel support for containers. Background Technology

[0002] Currently, the floor strength of standard container is tested at 7260 kg. The floor bears a uniformly distributed load, and the weight of a single coil of steel is typically below 7 tons. Coils weighing over 7 tons cannot be transported in standard containers. While most existing containerized steel coil transport racks can solve the load-bearing problem, they primarily use wooden frames or triangular blocks for support and positioning. These reinforcement methods are not robust or stable, cannot meet impact testing requirements, and pose significant safety hazards. The steel coils can easily roll or slip out of the container, causing serious safety risks during cargo transport, potentially leading to accidents and economic losses. Furthermore, to save costs, steel coil racks are often loaded into containers with other goods when transported separately, sometimes resulting in damage to the steel coils or other types of cargo. Summary of the Invention

[0003] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a coil steel support for containers. This invention can meet the needs of transporting coil steel and steel strips of different outer diameters and widths in standard containers. At the same time, the flipping and positioning structure of this transport frame can effectively prevent safety hazards caused by impacts. It can also meet the needs of transporting multiple coil steel transport frames in a single 20GP / HC standard container.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

Detailed Implementation

[0033] Referring to the accompanying drawings, this embodiment provides a coiled steel support for containers, including a pallet frame 1, as shown in the attached figures. Figure 3 As shown, the pallet frame 1 includes a chassis 6, uprights 7, and an upper frame 8. The upper frame 8 is mounted on the chassis 6 via the uprights 7. The chassis 6 includes side beams 13 on the front and rear sides, multiple slotted channel steels 14 in the middle for forklifts to insert and transport, and a crossbeam 15 connecting the side beams 13 and the slotted channel steels 14.

[0034] Multiple positioning brackets 2 are detachably inserted into the top of the pallet frame 1, such as... Figure 4 As shown, the positioning frame 2 includes two round steel bars 34 and multiple support beams 35 connected between the two round steel bars 34.

[0035] The upper frame 8 has multiple pairs of through holes 9 on its left and right sides for passing round steel bars 34 through the positioning frame 2. On the base plate 6, a positioning sleeve 10 is provided for each through hole 9 for inserting the round steel bars 34 of the positioning frame 2. According to the requirements of coiled steel bars 11 with different outer diameters and widths, the number of positioning frames 2 is adjusted, and the coiled steel bars 11 are inserted between two adjacent positioning frames 2. The coiled steel bars 11 are positioned by the support beam 35 of the positioning frame 2.

[0036] The inner end faces on the left and right sides of the upper frame 8 are respectively provided with pallets 12 for supporting the coiled steel 11. The lower edge of the pallets 12 rests on the chassis 6. Placing the coiled steel 11 on the pallets 12 can make it more stable during transportation. At the same time, multiple reinforcing ribs 16 are connected between the bottom surface of the pallet 12 and the chassis 6 to enhance the support strength.

[0037] Corrugated side positioning components 3, which correspond to and fit with the corrugations of the container side panels 36, are respectively connected to the front and rear side beams 13 of the pallet frame 1. The corrugated side positioning components 3 are rotatably connected to multiple ear plates 25 provided on the pallet frame 1.

[0038] like Figure 5 As shown, the corrugated side positioning assembly 3 includes a side support plate 26, a corrugated positioning strip 27 and multiple rotating ears 28. The corrugated positioning strip 27 is connected to the outside of the side support plate 26 by bolts and washers. The corrugated shape meshes with the container side plate 36, enabling displacement positioning along the length of the container. The rotating ears 28 are connected to the inside of the side support plate 26 and hinged to the ear plate 25.

[0039] The rotating ear 28 is provided with a rotating hole 29 and a positioning hole 30, such as Figure 6 As shown, the ear plate 25 has a double sector plate structure, and the rotating ear 28 is inserted between the double sector plates. A pin 31 is fixed on the inner side of the ear plate 25. The pin 31 passes through the rotating hole 29 of the rotating ear 28. A locking elbow bolt 32 and an unlocking elbow bolt 33 are respectively provided on the outer side of the ear plate 25 corresponding to the positioning hole 30 of the rotating ear 28.

[0040] like Figure 7 As shown, when the coiled steel 11 needs to be used for transportation, rotate the corrugated side positioning component 3 to insert the locking elbow bolt 32 into the positioning hole 30. The corrugated positioning strip 27 is horizontal and matches the container side plate 36 to realize the displacement positioning of the coiled steel 11 support.

[0041] like Figure 8 As shown, when it is necessary to pick up and transport the coiled steel 11 bracket, rotate the corrugated side positioning component 3, insert the unlocking elbow bolt 33 into the positioning hole 30, and the corrugated positioning strip 27 is in the vertical direction to release the positioning, so that the coiled steel 11 bracket can be picked up and transported by forklift.

[0042] like Figure 9 , 10 As shown in Figures 11 and 12, retractable pin assemblies 4 are respectively provided on the side beams 13 on both the front and rear sides of the pallet frame 1. The pin assemblies 4 correspond to the rope rings 5 ​​on both sides of the container and can be inserted into the corresponding rope rings 5 ​​for locking.

[0043] The pin assembly 4 includes a sleeve 17, a spring 18, and a connecting rod 19. The sleeve 17 is fixed on the tray frame 1. A U-shaped groove 20 is provided on the side surface of the sleeve 17. The connecting rod 19 is rotatably inserted into the sleeve 17 and can move along the axial direction of the sleeve 17. A semi-circular locking block 21 for locking with the rope ring 5 is provided at the outer end of the connecting rod 19. A locking rod 22 extending into the U-shaped groove 20 is provided on the inner end of the connecting rod 19. The two sides of the U-shaped groove 20 are a long groove 23 for sliding the locking rod 22 and a short groove 24 for positioning the locking rod 22, respectively. The spring 18 is sleeved on the connecting rod 19 and its two ends are respectively connected to the inner end face of the connecting rod 19 and the inner end face of the sleeve 17.

[0044] When in use, by pulling the locking rod 22 outward to extend the connecting rod 19, the semi-circular locking block 21 is locked onto the rope ring 5, and the locking rod 22 is rotated to lock the connecting rod 19 axially within the short groove 24 of the U-shaped groove 20, thereby achieving displacement positioning of the container in the height direction.

[0045] The usage method is as follows: like Figure 13 and 14 As shown, the number of positioning frames 2 is selected according to the requirements of coiled steel 11 and steel strip with different outer diameters and widths. Figure 13 The demonstration shows the state of multiple positioning frames 2 when transporting multiple narrow steel coils 11. Figure 14 The demonstration shows the state when only two positioning frames are selected when transporting a wide coil of steel 11.

[0046] Using a forklift, the pallet, coiled steel 11, and positioning bracket are transported into the container for positioning. Before positioning, the corrugated side positioning component 3 is in a vertical position and connected to the rotating lug 28 through the unlocking elbow bolt 33. During positioning, the unlocking elbow bolt 33 is removed, the side positioning block component is rotated to a horizontal position, and after matching with the corrugated shape of the container side plate 36, the locking elbow bolt 32 is inserted to achieve displacement positioning along the length of the container. Then, the pin assembly 4 is matched with the container rope ring 5 to achieve displacement positioning along the height of the container.

[0047] In addition, if there are a large number of coiled steel 11, multiple coiled steel 11 supports can be placed side by side to achieve a series configuration.

[0048] When transferring and transporting the coiled steel support separately, it can be done as follows: Figure 15 As shown, multiple coiled steel supports are transported side by side and stacked, meeting the need to transport multiple coiled steel supports at once within a 20GP / HC standard container, thus reducing transportation costs.

[0049] It is understood that the above specific description of the present invention is only for illustrating the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of the present invention.
