Description

Technical Field

[0001] This utility model relates to the field of transportation equipment manufacturing technology, specifically to a transportation box. Background Technology

[0002] Currently, some transport containers cannot effectively balance cargo loading capacity and return utilization. For example, transport containers used for transporting automobiles are limited in the types and quantities of vehicles that can be transported, resulting in a large workload and high costs for loading and unloading operations. Due to the restrictions on the types of goods transported, it is very likely that no matching return cargo can be found, leading to empty container returns and low return utilization.

[0003] Therefore, a transport container is needed to at least partially solve the above problems. Utility Model Content

[0004] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section.

[0093] This utility model provides a transport box for transporting automobiles or other general goods.

[0094] Now, refer to the appendix Figure 1 To be continued Figure 13 Exemplary embodiments according to the present invention will be described in more detail below.

[0095] like Figure 1 and Figure 2As shown, the transport container 100 includes a lower transport frame 10 and an upper transport frame 20. The upper transport frame 20 is located above the lower transport frame 10, and both the upper and lower transport frames 10 can be used to load goods. The lower transport frame 10 includes a base frame 11 and a lower side frame 12. The base frame 11 can be used to carry goods, and the lower side frame 12 is fixedly connected to the base frame 11. The lower side frame 12 is a structure fixedly connected to the base frame 11 and surrounds the lower loading space. The upper transport frame 20 includes an upper transport platform 21 and an upper side frame 22. The upper transport platform 21 can be used to carry goods, and the upper side frame 22 is fixedly connected to the upper transport platform 21. The upper side frame 22 is a structure fixedly connected to the upper transport platform 21 and surrounds the upper loading space. The upper transport frame 20 as a whole can move up and down along the height direction D3 of the transport container 100, thereby making the overall height of the transport container 100 adjustable.

[0096] According to the transport container 100 of this utility model, the upper transport frame 20 can be lowered, thereby reducing the overall height of the transport container 100. It can be used as a single-layer half-height container or as a double-layer transport container 100, offering flexibility in application. When used as a double-layer transport container 100, the upper transport platform 21 can be used for loading and unloading goods near the ground (e.g., ...). Figure 10 As shown), after loading and unloading, the container can be adjusted to a preset height using a forklift or similar means, avoiding high-altitude loading and unloading, resulting in low risk and simple operation. Furthermore, the transport container 100 is suitable for transporting a wide range of goods; even without matching truck cargo on the return trip, it can be used to load general cargo. Alternatively, two transport containers 100 can be nested within a standard container for return transport (e.g., ...). Figure 13 (As shown). The designed transport container 100 is flexible in its application, safe in loading and unloading, and has low return transport costs.

[0097] Preferably, the upper transport frame 20 can be moved such that the height of the transport container 100 is less than 1.6m, thereby enabling the transport containers 100 to be stacked vertically on the return trip (e.g., ...). Figure 11 As shown, it can be transported by rail, complies with railway height restrictions, and reduces return transport costs. For example, the upper transport frame 20 can be moved so that the transport container 100 can be used as a 1535mm half-height container or a 3100mm double-layer container. Furthermore, the single-layer height of the transport container 100 is less than 1.6m, and the double-layer height is less than 3.2m. The total weight of double-layer transport can reach 70T (such as transporting linear steel), reaching the maximum cargo capacity of the train, resulting in high transport efficiency. Understandably, when two transport containers 100 are stacked, the upper and lower layers can be connected by corner fittings and swivel locks.

[0098] In some specific embodiments, the upper transport frame 20 can move up and down via telescopic columns. For example... Figure 3As shown, the lower side frame 12 includes a first fixed column 12A, the lower end of which is fixedly connected to the base frame 11. The upper side frame 22 includes a first movable column 22A, which is fixedly connected to the upper transport platform 21. The first movable column 22A is sleeved with the first fixed column 12A and can move relative to it along the height direction D3. For example, the first fixed column 12A and the first movable column 22A extend along the height direction D3 of the transport box 100. The first movable column 22A has a columnar hollow structure, and the first fixed column 12A at least partially penetrates the cavity of the first movable column 22A and can move relative to it along the axial direction. Alternatively, the first fixed column 12A has a columnar hollow structure, and the first movable column 22A at least partially penetrates the cavity of the first fixed column 12A and can move relative to it along the axial direction.

[0099] To fix the height of the upper transport frame 20, the transport box 100 also includes first fasteners 30A / 30B, which are used to insert into the first fixed column 12A and the first movable column 22A. Correspondingly, both the first fixed column 12A and the first movable column 22A have at least one first insertion hole 31A for the first fasteners 30A / 30B to insert into. It is understood that when the upper transport frame 20 moves to a preset height, at least one first insertion hole 31A of the first fixed column 12A and at least one first insertion hole 31A of the first movable column 22A are aligned.

[0100] Preferably, at least one of the first fixed column 12A and the first movable column 22A is provided with at least two first insertion holes 31 at intervals along the height direction D3, so that the upper transport frame 20 can be fixed to different heights. More preferably, two first insertion holes 31 are provided at the same height, resulting in more balanced force distribution. Here, there is no limitation on the number of first insertion holes 31A at different heights or the number of first insertion holes 31A at the same height.

[0101] Optionally, such as Figure 2 and Figure 3 As shown, the first insertion hole 31A is a through hole along the width direction D2, and the first fixing member 30A passes through it along the width direction D2. Optionally, as... Figure 7 and Figure 10 As shown, the first insertion hole 31A is a through hole along the length direction D1, and the first fixing member 30B passes through it along the length direction D1. The first fixing members 30A / 30B are, for example, pluggable pins.

[0102] After the upper transport frame 20 is raised to the required height using a forklift or hoisting equipment, the first fixing member 30A secures the first movable column 22A and the first fixed column 12A, thus fixing the height of the upper transport frame 20. When lowering the height of the upper transport frame 20, the first fixing member 30A is released, and the upper transport frame 20 is lowered using a forklift or similar means, for example, to its lowest position. The first fixing member 30A then secures the first movable column 22A and the first fixed column 12A. Furthermore, the upper transport platform 21 can be equipped with a hook 28, allowing it to be lifted using non-dedicated hoisting equipment such as a gantry crane.

[0103] To ensure stable support for the upper transport frame 20, first fixed columns 12A are provided on both sides of the base frame 11 along the width direction D2 of the transport box 100, with at least two first fixed columns 12A on each side spaced apart along the length direction D1 of the transport box 100.

[0104] The upper side frame 22 also includes a second fixed column 22C and a second movable column 22D. The second fixed column 22C is fixed to the upper transport platform 21. The second movable column 22D is sleeved with the second fixed column 22C and can move relative to it along the height direction D3. The top of the second movable column 22D is provided with a corner piece 27, which has a corner hole.

[0105] The corner piece 27 at the top of the second movable column 22D facilitates the hoisting and stacking of the transport container 100, making it suitable for combined sea and land transport. Preferably, the spacing of the corner piece 27 in the length direction D1 and width direction D2 of the transport container 100 conforms to the international standard corner piece spacing for transport containers, adapting to standard hoisting tools. The second fixed column 22C and the second movable column 22D allow the height of the top of the transport container 100 to be adjustable. For example, in railway transport, when passing through tunnels, the second movable column 22D can be adjusted so that the height of the transport container 100 meets the height limit; when hoisting the transport container 100, the second movable column 22D can be raised so that its top surface is higher than the top surface of the goods, facilitating the hoisting of the transport container 100.

[0106] To fix the height of the second movable column 22D, the transport box 100 further includes second fasteners 23A / 23B for inserting into the second movable column 22D and the second fixed column 22C. Correspondingly, the second fixed column 22C and the second movable column 22D each have at least one second insertion hole 31B for inserting the second fasteners 23A / 23B. When the second movable column 22D is adjusted to a preset height, at least one second insertion hole 31B of the second fixed column 22C aligns with at least one second insertion hole 31B of the second movable column 22D, and the second fasteners 23A / 23B insert into the second insertion hole 31B to fix the second movable column 22D and the second fixed column 22C. Preferably, at least one of the second fixed column 22C and the second movable column 22D is provided with at least two second insertion holes 31B spaced apart along the height direction D3, so that the second movable column 22D can be adjusted to different heights. More preferably, two second insertion holes 31B are provided at the same height for more balanced force distribution. There is no limit to the number of second sockets 31B at different heights or at the same height.

[0107] Optionally, such as Figure 3 As shown, the second insertion hole 31B is a through hole along the width direction D2, and the second fixing member 23A passes through it along the width direction D2. Optionally, as shown... Figure 7 and Figure 10 As shown, the second insertion hole 31B is a through hole along the length direction D1, and the second fastener 23B passes through it along the length direction D1. The second fasteners 23A / 23B are, for example, pluggable pins.

[0108] With this design, the first fixed column 12A and the first movable column 22A can achieve multiple height adjustments for the lower transport space, and the second fixed column 22C and the second movable column 22D can achieve multiple height adjustments for the upper transport space. Through the adjustment of the two sets of columns, multiple height distributions can be achieved for the upper and lower spaces of the container, while the overall height of the container meets the railway transport clearance requirements.

[0109] like Figure 7 As shown, the transport box 100 also includes a rope 40, which is used to control the up-and-down movement of the second movable column 22D. Specifically, the second fixed column 22C is provided with a fixed rope loop 41, and the second movable column 22D is provided with a movable rope loop 42. The fixed rope loop 41 is located above the movable rope loop 42. One end of the rope 40 is connected to the movable rope loop 42, and the other end of the rope 40 passes through the fixed rope loop 41. Therefore, pulling the rope 40 can pull the second movable column 22D upward, and releasing the rope 40 can control the second movable column 22D to move downward under its own weight. Personnel can control the up-and-down movement of the second movable column 22D from a lower position using the rope 40, which is convenient, time-saving, and labor-saving.

[0110] Specifically, one of the outer layers of the second fixed column 22C and the second movable column 22D has a groove 43 to facilitate the connection of the rope 40 to the rope ring and the pulling of the rope ring. For example, when the second fixed column 22C is sleeved on the outer layer of the second movable column 22D, the second fixed column 22C has a groove 43 along the height direction D3, the fixed rope ring 41 is located above the groove 43, and the movable rope ring 42 moves within the groove 43. Alternatively, when the second movable column 22D is sleeved on the outer layer of the second fixed column 22C, the second movable column 22D has a groove 43 along the height direction D3, the movable rope ring 42 is located below the groove 43, and the fixed rope ring 41 moves relative to the movable rope ring 42 within the groove 43.

[0111] The transport container 100 is also equipped with a guide rope loop 44 for guiding the extension direction of the rope 40. The extension direction of the rope 40 can be changed after passing through the guide rope loop 44. The other end of the rope 40 is connected to the lower transport frame 10 or the upper transport platform 21 via a rope tightening device, which pulls and releases the rope 40. The rope tightening device is, for example, a ratchet tightener.

[0112] In some specific embodiments, the spacing of the corner brackets 27 along the length direction D1 and width direction D2 of the transport container 100 conforms to the international standard corner bracket spacing for transport containers. Simultaneously, the first movable upright 22A is fixedly connected to the second fixed upright 22C. For example... Figure 1 As shown, two first movable columns 22A are located on both sides of a second fixed column 22C along the length direction D1 and are fixedly connected to the second fixed column 22C. Therefore, the support points of the lower transport frame 10 on the upper transport frame 20 are reasonably distributed, resulting in stable support.

[0113] In some specific embodiments, the lower side frame 12 further includes a third fixed column 12B, the lower end of which is fixedly connected to the base frame 11. The upper side frame 22 includes a third movable column 22B, which is fixedly connected to the upper transport platform 21. The third movable column 22B is sleeved with the third fixed column 12B and can move relative to it along the height direction D3. When the third movable column 22B moves relative to the third fixed column 12B to a predetermined position, the third movable column 22B exerts an upward pulling force on the third fixed column 12B. The position of the third movable column 22B relative to the third fixed column 12B is determined by the first fixing member 30A when the first fixed member 30A fixes the first movable column 22A to the first fixed column 12A at the predetermined position.

[0114] It should be noted that the connection between the third movable column 22B and the third fixed column 12B includes both connections where the third movable column 22B is located on the outer layer and the third fixed column 12B is located on the inner layer, and connections where the third fixed column 12B is located on the outer layer and the third movable column 22B is located on the inner layer. For example... Figure 4 As shown, the third movable column 22B has a hollow structure and is fitted onto the outside of the third fixed column 12B.

[0115] Specifically, to achieve the pulling force of the third movable column 22B on the third fixed column 12B at a predetermined position, such as... Figures 4 to 6 As shown, one of the third fixed column 12B and the third movable column 22B located in the inner layer has an outwardly protruding part 32 on its outer periphery, and the one of the third fixed column 12B and the third movable column 22B located in the outer layer is provided with a third fixing member. At a predetermined position of the third movable column 22B relative to the third fixed column 12B, the third fixing member abuts against the protruding part 32 to prevent the third fixed column 12B from moving downward relative to the third movable column 22B.

[0116] The protrusion 32 is a protrusion that extends outward from the side wall of the third fixed column 12B or the third movable column 22B. It may surround the side wall or be partially provided. The protrusion 32 may be an integral component with the third fixed column 12B or the third movable column 22B, or it may be a component fixedly connected to the outer periphery of the third fixed column 12B or the third movable column 22B.

[0117] Optionally, such as Figure 4 and Figure 5 As shown, the third fixing member is a spring pin 33A. At a first predetermined position relative to the third fixed column 12B, the spring pin 33A passes through one of the outermost columns of the third fixed column 12B and the third movable column 22B, and abuts against the protrusion 32. The first predetermined position is not limited to one. In other words, the protrusion 32 can be provided at intervals of one, two, or more along the height direction D3. The spring pin 33A can also be provided at intervals of one, two, or more along the height direction D3.

[0118] For example, the outer side of the third fixed column 12B has a protrusion 32, and the third movable column 22B is sleeved on the outer side of the protrusion 32 of the third fixed column 12B. The third movable column 22B is provided with a spring pin 33A. When the spring pin 33A is in the retracted position, the third movable column 22B can move up and down. When the third movable column 22B moves relative to the third fixed column 12B to a first predetermined position, the spring pin 33A pops out and abuts against the lower surface of the protrusion 32. Therefore, the spring pin 33A can exert an upward force on the protrusion 32, that is, the third movable column 22B can exert an upward force on the third fixed column 12B.

[0119] Optionally, such as Figure 4 and Figure 6 As shown, the third fixing member is an end plate 33B with an opening. The end plate 33B is fixedly connected to the end of one of the third fixed column 12B and the third movable column 22B located on the outer layer. At the second predetermined position of the third movable column 22B relative to the third fixed column 12B, the end plate 33B abuts against the protrusion 32.

[0120] Understandably, the third fixed column 12B or the third movable column 22B located on the outer layer is constructed as a hollow column, and the protrusion 32 can be accommodated in the hollow part. The size of the opening of the end plate 33B is set so that the part of the third fixed column 12B or the third movable column 22B without the protrusion 32 can pass through, but the protrusion 32 cannot pass through.

[0121] For example, the outer side of the third fixed column 12B has a protrusion 32, and the third movable column 22B is sleeved on the outer side of the protrusion 32 of the third fixed column 12B. An end plate 33B is fixedly connected to the lower end of the third movable column 22B. When the third movable column 22B moves upward to the second predetermined position, the upper surface of the end plate 33B abuts against the lower surface of the protrusion 32. Therefore, the end plate 33B can exert an upward force on the protrusion 32, that is, the third movable column 22B can exert an upward force on the third fixed column 12B.

[0122] In some specific embodiments, the end plate 33B and the spring pin 33A can be provided simultaneously, and the first predetermined position is different from the second predetermined position. In the first predetermined position, the third movable column 22B has not moved to the point where the end plate 33B abuts against the protrusion 32.

[0123] Along the length direction D1, the third fixed column 12B can be located between the two first fixed columns 12A to prevent the middle of the base frame 11 from sinking and bending due to excessive load. Furthermore, the third fixed column 12B can also be located at both ends of the transport box 100 along the length direction D1, such as at the four corners of the base frame 11. The arrangement of the third fixed column 12B and the third movable column 22B also prevents the upper transport frame 20 from detaching from the lower transport frame 10 during upward movement.

[0124] It should be noted that there is no limit to the number of third fixed posts 12B installed between the two first fixed posts 12A; there can be one, two, or more. For example... Figure 1 As shown, three third fixed columns 12B are provided between two first fixed columns 12A on the same side of the middle of the transport box 100 along the length direction D1.

[0125] like Figure 1 and Figure 10As shown, to ensure the stability of the upper transport frame 20, the transport box 100 also includes a connecting column 50 and a fixing device 51. The connecting column 50 is located on at least one side of the width direction D2 of the transport box 100. Both ends of the connecting column 50 are pivotally connected to the upper transport frame 20 and the base frame 11, respectively, and the lower end of the connecting column 50 can slide along the length direction D1 of the transport box 100. That is, the connection position between the upper end of the connecting column 50 and the upper transport frame 20 remains unchanged, while the connecting column 50 pivots during the up-and-down movement of the upper transport frame 20, and its lower end slides along the length direction D1 of the transport box 100. After the upper transport frame 20 is in place, the lower end of the connecting column 50 is fixed to the base frame 11 by the fixing device 51. The connecting column 50 makes the up-and-down movement of the upper transport frame 20 more stable and also provides support after the movement is completed. The fixing device 51 is, for example, a pin and a hinge plate fixed to the base frame 11. The connecting column 50 is fixed to the base frame 11 by inserting the pin into the hinge plate and the hole at the lower end of the connecting column 50. In some specific embodiments, at the lowest position of the upper transport frame 20, the third movable column 22B abuts against the base frame 11. At the same time, the third movable column 22B or the third fixed column 12B is provided with a limiting member 34, which restricts (prevents) the third movable column 22B from moving upward relative to the third fixed column 12B. The first fixing member 30A / 30B fixes the first movable column 22A, and the fixing device 51 fixes the connecting column 50. For example, the third movable column 22B is sleeved on the outside of the third fixed column 12B. The third movable column 22B is provided with a spring pin. The position of the spring pin on the third movable column 22B is set so that when the upper transport frame 20 is in the lowest position, it abuts against the lower surface of the protrusion 32 of the third fixed column to prevent the third movable column 22B from moving upward relative to the third fixed column 12B.

[0126] With this design, when the upper transport frame 20 is in its lowest position, the transport box 100 forms an integral load-bearing structure with a double-layered base frame (upper transport platform and base frame) through the fixing of the first fixed column 12A to the first movable column 22A, the fixing of the third movable column 22B to the third fixed column 12B, and the fixing of the connecting column 50. That is, when the upper transport frame 20 is in its lowest position, the base frame 11 is unloaded, and the connection between the base frame 11 and the upper transport platform 21 connects the base frame 11 and the upper transport platform 21 into an integral steel structure, thereby increasing the load-bearing capacity of the upper transport platform 21.

[0127] like Figure 1 and Figure 8As shown, the lower transport frame 10 includes corner brackets 13, which are disposed on both sides of the base frame 11 along the width direction D2 of the transport container 100. Preferably, multiple corner brackets 13 are spaced apart along the length direction D1 of the transport container 100. The base frame 11 is provided with multiple sets of corner brackets 13, making the transport container 100 suitable for connection with locking devices on railway trains and road trailers.

[0128] Furthermore, such as Figure 9 As shown, the length of the corner hole of the top corner piece 27 and / or bottom corner piece 13 is taken as the upper limit tolerance dimension of the standard corner hole, which increases the mobility of the transport box 100 when the two transport boxes 100 are stacked and transported, and buffers the impact load on the box and the vehicle.

[0129] like Figure 3 and Figure 7 As shown, the upper side frame 22 also includes an upper side beam 24, a lower side beam 25, and a connecting beam 26. Both the lower side beam 25 and the upper side beam 24 are arranged along the length direction D1 of the transport box 100 and are fixedly connected to the first movable column 22A. The two lower side beams 25 are respectively fixedly connected to both sides of the upper transport platform 21. The upper side beam 24 is located above the lower side beam 25, and the two ends of the connecting beam 26 are respectively connected to the upper side beam 24 and the lower side beam 25, with the connecting beam 26 forming an angle with the height direction D3. Preferably, the two ends of the connecting beam 26 are fixedly connected to the upper side beam 24 and the lower side beam 25, respectively. In some other embodiments, the connecting beam 26 is configured as a corrugated plate (see reference). Figure 12 This facilitates the transportation of liquid-filled goods. The upper side frame 22 is a structure assembled from the upper side beam 24, the lower side beam 25, the connecting beam 26, and the first movable column 22A. Therefore, the upper side frame 22 has a stable structure and a firm connection with the upper transport platform 21.

[0130] According to this utility model, the transport box, through the connection of a first fixed column and a first movable column, and the connection of a second fixed column and a second movable column, combined with multiple insertion holes of different heights, allows for adjustment of the height of the upper and lower transport spaces and the overall height of the box. By combining the heights of the two sets of columns, various height distributions between the upper and lower layers can be achieved to adapt to the loading requirements of different types of goods, while the overall height of the box meets railway boundary dimensional requirements. The transport box has a double-layer base frame structure, with the columns fixed by fasteners. The double-layer base frame can be combined into a whole, resulting in high structural strength and strong load-bearing capacity.
