Description

Technical Field

[0001] The utility model relates to the technical field of logistics transportation, and particularly relates to a transportation frame for transporting loose pieces of a van vehicle. Background Art

[0002] Due to its large volume, the transportation of a van vehicle itself has many limitations. When transported by a bulk carrier, it occupies a large space, resulting in a high transportation cost. Therefore, for the compartments of van vehicles that need to be transported by sea, most of them adopt a split structure, that is, the side plates, chassis, top plates, and end frames of the compartment are separately manufactured at the production site. After multiple plate components are packaged, they are loaded into a standard container. After transporting the plate components to the place of use, the plate components are assembled to form a complete compartment.

[0003] When packaging the plate components, a special transportation frame is needed to fix multiple plate components. However, in the actual use process of the existing transportation frame, it is difficult to position the plate components well, and the plate components are prone to serious bumps during transportation, which brings a lot of inconvenience to subsequent assembly. Summary of the Utility Model

[0033] Next, with reference to the drawings and specific embodiments, the present utility model will be further described:

[0034] As shown in Figure 1 ,2 As shown in Figures 3, 4, 5, 6, 7, 8, and 9, a transport frame for loose pieces of a transport van of an embodiment of the present utility model includes a chassis 10 and two end frames 20. The two end frames 20 are respectively located above the two ends of the chassis, and the end frames 20 are fixedly engaged with the chassis 10. At both ends of the chassis 10, there is respectively provided a bottom cross beam 11. At the top of each end frame 20, there is provided a top cross beam 21. The top cross beams 21 of the two end frames 20 are respectively located above the two bottom cross beams 11 of the chassis 10. The two top cross beams 21 and the two bottom cross beams 11 all extend along the width direction of the transport frame. On the two bottom cross beams 11, there are respectively provided a plurality of fixed support members 13. On the top cross beam 21, there are provided a plurality of movable support members 23. The movable supports 23 are pivotally connected to the top cross beam 21, enabling the movable support members 23 to flip towards the inner side of the top cross beam 21. On the movable support members 23, there are provided two opposite stop portions, and a receiving groove is formed between the two stop portions. The width of the receiving groove is equivalent to the thickness of the loose pieces. When the movable support members 23 are flipped to the inner side of the top cross beam 21, the edges of the loose pieces on the transport frame can be inserted into the receiving grooves of the movable support members 23. The plurality of fixed support members 13 and the plurality of movable support members 23 at the same end of the transport frame are arranged in a one-to-one correspondence up and down. When a plurality of loose pieces are placed on the transport frame for packing, the upper parts of the edges of the loose pieces are limited in the receiving grooves of the movable support members 23, and the bottoms of the loose pieces are supported by the fixed support members 13. Specifically, the upper parts of the two edges of the loose pieces are respectively limited by two opposite movable support members 23 on the two top cross beams 21, and the bottoms of the two edges of the loose pieces are respectively supported by two opposite fixed support members 13 on the bottom cross beam 11, so that the loose pieces are relatively fixed with the transport frame after being loaded into the transport frame.

[0035] In the present utility model, fixed support members 13 are provided on the bottom cross beam 11 of the chassis 10 to support the bottoms of the loose pieces, and movable support members 23 are provided on the top cross beam 21. After the movable support members 23 are flipped inwards, they can limit the loose pieces through the receiving grooves thereon, preventing the loose pieces from shaking during transportation, thus effectively solving the problem of the loose pieces being knocked during transportation due to shaking, and ensuring that the loose pieces can meet the assembly requirements after being transported to the place of use.

[0036] In a preferred embodiment, a plurality of mounting seats 212 are provided on the top cross beam 21. The mounting seats 212 are fixedly welded to the upper surface 211 of the top cross beam 21. The movable support member 23 includes a support arm 231 and a connecting plate 232. One end of the support arm 231 is pivotally connected to the mounting seat 212 through a rotating shaft, and the connecting plate 232 is fixedly welded to the other end of the support arm 231. The two stop portions described above are baffles 233 formed by bending both sides of the connecting plate 232. The two baffles 233 and the connecting plate 232 form a U-shaped structure. An accommodation groove is formed by enclosing the two baffles 233. When transporting loose sheets, the two baffles 233 are respectively located on both sides of the loose sheet, and the connecting plate 232 is placed at the end of the loose sheet. In addition, the movable support member 23 is arranged on the mounting seat 212 on the upper surface 211 of the top cross beam 21, and the support arm 231 of the movable support member 23 is pivotally connected by a rotating shaft. When transporting loose sheets, the support arm 231 can be turned inward, so that the two baffles 233 on the movable support member 23 extend into the space between the two top cross beams 21 of the transport frame, so that the movable support member 23 can limit the loose sheet in this space. At the same time, when hoisting the loose sheet into the transport frame, the movable support member 23 is turned outward, so that the movable support member 23 is located above the top cross beam 21 to avoid the above space, so that the loose sheet can be placed between the two top cross beams 21 from top to bottom, avoiding interference between the movable support member 23 and the loose sheet.

[0037] The above-mentioned fixed support member 13 includes a bottom wall 131 and two side walls 132 respectively bent upward from both sides of the bottom wall 131. The two side walls 132 and the bottom wall 131 enclose a receiving groove for accommodating loose sheets. The bottom wall 131 and the two side walls 132 are both fixedly welded to the inner side surface 111 of the bottom cross beam 11. By providing a receiving groove on the fixed support member 13, while supporting the loose sheet by the fixed support member 13, it is also possible to limit the bottom of the loose sheet to swing in the width direction of the transport frame, further preventing the loose sheet from swinging. Among the multiple fixed support members 13 on the same bottom cross beam 11, the height of the bottom wall 131 of the two fixed support members 13 located at both ends of the bottom cross beam 11 is less than the height of the bottom walls of the other fixed support members 13. Thus, as Figure 8 shown, after loading a plurality of loose sheets on the transport frame, the heights of the loose sheets on both sides of the transport frame are relatively low. When the transport frame filled with loose sheets is sent into a standard container, the upper ends of the loose sheets on both sides are lower than the upper ends of the other loose sheets because they are supported by the fixed support members 13 with a lower height position. In this way, when the transport frame is sent into the cargo space of the container from the door end of the container, the loose sheets on both sides are in a lower position and can avoid the two corner fittings at the door end of the container, avoiding interference between the loose sheets and the corner fittings at the door end of the container.

[0038] At four corner parts of the chassis 10, there are upward protruding plug-in parts 15 provided. The end frame 20 includes two columns 22. The tops of the two columns 22 are respectively connected to two ends of the top cross beam 21 and extend downward. On the bottom end surface of the column 22, there is a plug-in hole 221. The two plug-in parts 15 at the same end of the chassis 10 are respectively inserted upward into the plug-in holes 221 of the two columns 22 of the end frame 20, thereby fixedly connecting the end frame 20 to the end of the chassis 10. Of course, in other embodiments, it can also be that the plug-in parts 15 are arranged at the bottom of the column 22. Correspondingly, the plug-in holes 221 are arranged at the corner parts of the chassis 10. In this way, during the return transportation process, the end frame 20 can be detached from the chassis 10 and placed flat on the chassis 10, reducing the space occupied by the transportation frame during return transportation and lowering the transportation cost.

[0039] Between the two sides of the two end frames 20, there is a side frame 30 provided respectively. Two ends of the side frame 30 are respectively connected to the two end frames 20, and the bottom is connected to the side of the chassis 10. By providing the side frame 30, the whole transportation frame has better strength. The side frame 30 includes a top side beam 31 and two inclined support rods 32. On the column 22 of the end frame 20, there is a socket 222 provided. On the socket 222, there is a slot 223 with an open top. At two ends of the top side beam 31, there is a downward extending pin 312 provided respectively. The top side beam 31 is located between the two columns 22 on the same side at the two ends of the transportation frame. The pin 312 is inserted downward into the slot 223 of the socket 22. The tops of the two inclined support rods 32 are detachably connected to the middle of the top side beam 31, and the bottoms are respectively pivotally connected to the two ends of the chassis 10. By fitting the end of the top side beam 31 with the column 22 in a plug-in manner, and at the same time, the top of the inclined support rod 32 is detachably fitted with the top side beam 31. During the return transportation process, the side frame 30 can be detached from the two end frames 20 and the chassis 10. The two inclined support rods 32 are turned downward and placed flat on the chassis. The removed top side beam 31 can also be placed flat on the chassis 10, reducing the space occupied by the transportation frame during return transportation. There is a connecting plate 311 welded to the middle of the top side beam 31. The tops of the two inclined support rods 32 are connected to the middle of the top side beam 31 through a first connecting bolt, that is, the first connecting bolt passes through the tops of the two inclined support rods 32 and the connecting plate 311, connecting the tops of the two inclined support rods 32 to the middle of the top side beam 31. The bottoms of the two inclined support rods 32 are respectively connected to the two ends of the chassis 10 through a second connecting bolt, pivotally connecting the two inclined support rods 32 to the chassis 10. After removing the first connecting bolt, the two inclined support rods 32 can be turned downward to be placed flat on the chassis 10.

[0040] On both sides of the above-mentioned chassis 10, a bottom side beam 12 is respectively provided. The two ends of the bottom side beam 12 are respectively connected to the bottom cross beams 11 at both ends of the chassis 10. The bottom side beam 12 includes an outer side wall and a support wall formed by bending outward from the bottom of the outer side wall. The support wall and the outer side wall together enclose a receiving space. After the two inclined support rods 32 are turned downward, the two inclined support rods 32 are located in the receiving space, ensuring that the inclined support rods 32 will not extend beyond the side of the chassis 10 when the transport frame is in the state of being returned and folded. Of course, the removed top side beam 31 can also be received in this receiving space. A stop block 16 is also welded on the bottom side beam 12. The stop block 16 is arranged at a certain distance from the outer side wall of the bottom side beam 12. After the two inclined support rods 32 are placed in the receiving space, the stop block 16 is used to stop the outer sides of the two inclined support rods 32 after being folded downward, preventing the inclined support rods 32 from swinging outward during return transportation, so that the inclined support rods 32 can be stably received in the receiving space on the bottom side beam 12.

[0041] In the above structure, both the slot 223 and the pin 312 are tapered with a wider upper part and a narrower lower part. When the pin 312 is inserted into the slot 223 from top to bottom, due to their tapered structures, the pin 312 is tightened and positioned, so that the top side beam 31 can be more firmly engaged with the column 22, ensuring that the top side beam 31 can provide better support for the two end frames 20 along the longitudinal direction of the transport frame.

[0042] To facilitate the movement of the transport frame and enable the transport frame filled with loose sheets to be conveniently moved into the interior of the container, two longitudinal beams 14 extending along the length direction of the chassis are provided on the chassis 10. The cross-section of the longitudinal beam 14 is set as an Ω shape. By using this cross-sectional shape of the longitudinal beam 14, a fork slot 141 is formed below the longitudinal beam 14. Thus, the transport frame can be moved by a forklift.

[0043] As Figure 10 、 11 shown, the present invention provides a transport frame for transporting loose sheets of a van in another embodiment. Different from the way of plugging and fixing the end frame and the chassis in the above embodiment, in this embodiment, the end frame includes two columns respectively extending downward from both ends of the top cross beam. The bottom of the column is pivotally connected to the chassis through a pivot shaft. Thus, the column can be folded inward and placed above the chassis, and then the entire end frame is placed flat on the chassis.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
