[0028] Reference Figures 1 to 9 This utility model provides a container with a removable top cover. The container includes a base frame 10, a wall panel assembly 20, a top cover 40, and a door assembly 30.
[0029] The underframe 10 is the basic load-bearing structure of the container, composed of a high-strength steel frame and a wooden or steel floor 11, providing sufficient load-bearing rigidity and strength. Multiple sets of deformable supports 12 are installed within the underframe 10. Each set of supports 12 can switch between a folded position and an upright position: in the folded position, the supports 12 are fully retracted and flush with the surface of the floor 11, forming a complete flat load-bearing surface, allowing the container to transport general boxed goods, palletized goods, etc.; in the upright position, the supports 12 unfold to form a saddle-shaped support, with its supporting surface abutting against the outer contour of the rolled goods 60, effectively supporting and securing the rolled goods 60 to prevent rolling and displacement during transportation. The support 12 configuration enables the container to perform both general cargo transportation and dedicated transport of rolled goods 60, improving the equipment's versatility and efficiency.
[0030] The wall panel assembly 20 is connected to the perimeter of the underframe 10, forming the lateral enclosure structure of the container. The wall panel assembly 20 includes at least one side wall 21 and at least one end wall 22, which are typically made of corrugated sheet to enhance structural strength. The side wall 21 and end wall 22 are fixed to the underframe 10 by welding or bolting to ensure the stability of the overall structure.
[0031] The top cover 40 is operably connected to the top of the wall panel assembly 20, forming an openable and closable structure for the top of the container. When the top cover 40 is opened, a first opening 51 is formed in the top of the wall panel assembly 20, which provides a passage for loading and unloading goods from the top.
[0032] The door assembly 30 includes at least one operable door body. The door body is a side door 31 operablely connected to the side of the wall panel assembly 20 and / or an end door 32 operablely connected to the end face of the wall panel assembly 20. When the side door 31 is opened, a second opening 52 is formed, and when the end door 32 is opened, a third opening 53 is formed.
[0033] The wall panel assembly 20, door assembly 30, and top cover 40 form a closed or semi-closed container, providing reliable protection for goods and flexible loading and unloading methods.
[0034] The container provided by this utility model, when the first opening 51 formed by the opening of the top cover 40, the second opening 52 formed by the side door 31, and / or the third opening 53 formed by the end door 32 are interconnected, together constitute a large loading and unloading port. This allows large-sized goods to be easily loaded and unloaded from multiple directions, significantly improving loading and unloading efficiency. For example, when loading and unloading steel coils, the top cover 40 and the side door 31 can be opened simultaneously, and the crane can directly lift the steel coils from the top and adjust them through the lateral space, avoiding the difficulty of adjusting the position of goods through narrow doorways in traditional containers.
[0035] Generally, the wall panel assembly 20 has a top beam at the top, a bottom beam at the bottom, and corner posts on the sides. The top beam, bottom beam, and corner posts constitute the frame of the container, and the wall panels are fixed to this frame to form a closed enclosure; at the same time, the top cover 40 and the base frame 10 are also fixed to this frame. In other implementations of this scheme, the wall panel assembly 20 itself has sufficient structural strength and can be directly connected to the base frame 10 and the top cover 40 to form a stable container structure, thereby potentially achieving a simplified design that omits the top beam, as will be discussed below.
[0036] In this solution, the door assembly 30 can be a single, integral door panel. Specifically, the side door 31 and / or end door 32 do not involve openings in the existing wall panel; instead, they function as movable wall panel components, directly replacing the entire area occupied by the fixed wall panel. Taking the side door 31 as an example: the side frame of the container consists of a top beam, a bottom beam, and corner posts on the front and rear sides forming a lateral opening. The side door 31 is hinged to one edge of this opening, and its dimensions are designed to completely cover it. When the side door 31 is open, a second opening 52 is formed on the side wall 21. The size of the second opening 52 is substantially the same as the usable area of the side wall 21, thus providing unobstructed lateral passage for large cargo. In other implementations of this solution, partial openings can be made in the wall panel and doors can be installed to meet different access requirements.
[0037] Optionally, the side door 31 is hinged to the wall panel assembly 20.
[0038] In some embodiments, the upper edge of the side door 31 is hinged to the top cover 40 via a hinge, and the side door 31 can be opened upward to form a structure similar to a canopy, which facilitates loading and unloading of goods and provides a certain degree of rain protection.
[0039] In other embodiments, the lower edge of the side door 31 is hinged to the base frame 10, and the side door 31 can be opened downward to form a structure similar to a suspension bridge, which facilitates loading and unloading of goods directly from the side.
[0040] In some embodiments, the side edge of the side door 31 is hinged to the end wall 22, allowing the side door 31 to open to one side like a conventional door, saving space. The side door 31 is connected to the front wall 22 and the rear wall 22 by hinges, which are heavy-duty industrial hinges with sufficient load-bearing capacity and durability.
[0041] The different hinge methods described above can be selected according to actual usage requirements, improving the adaptability of the container. Specifically, heavy-duty hinges can be used to ensure the stability and durability of the door opening.
[0042] When the side door 31 is opened, the support of the container structure on that side is weakened. Optionally, the bottom frame 10 can thicken and / or increase the height of the bottom side beam on the side where the side door 31 is located, forming a reinforced bottom side beam 23. By reinforcing the bottom side beam 23, the weakness of weakened support after the side door 31 is opened is compensated for, ensuring the overall rigidity and strength of the container. The reinforced bottom side beam 23 can also better withstand the stress generated by the frequent opening and closing of the side door 31, extending its service life.
[0043] Optionally, the side door 31 is a detachable side door 31a. The detachable side door 31 is connected to the wall panel assembly 20 by multiple locking devices such as locking rods. After the locking devices are unlocked, the side door 31 can be moved away from the container as a whole, forming a fully open side opening (i.e., the second opening 52), which facilitates the loading and unloading of oversized goods or the maintenance of equipment inside the container.
[0044] In this design, the wall panel assembly 20 includes two opposing side walls 21, each optionally equipped with a side door 31. The symmetrical arrangement of the side doors 31 allows for loading and unloading of the container from both sides, improving operational flexibility and significantly increasing operational efficiency. The two side doors 31 can open independently or simultaneously, forming a larger loading and unloading space in conjunction with the opening of the top cover 40.
[0045] Optionally, the top cover 40 includes an integrally formed top beam 42, which is removed along with the top cover 40 when the top cover 40 is opened.
[0046] Optionally, the side wall 21 with the side door 31 does not have a top beam. In this embodiment, the longitudinal structural beam at the top of the side wall 21 is removed. When the top cover 40 is opened and the side door 31 is opened, the first opening 51 and the second opening 52 are fully connected, forming a continuous opening from the top to the end. Optionally, the end wall 22 with the end door 32 does not have a top beam. In this embodiment, the transverse structural beam at the top of the end wall 22 is removed. When the top cover 40 is opened and the end door 32 is opened, the first opening 51 and the third opening 53 are fully connected, forming a continuous opening from the top to the end. According to this solution, it is convenient for longitudinal loading and unloading of large-sized goods. Optionally, the beam-free design compensates for structural rigidity by strengthening the corner posts, ensuring the stability of the container.
[0047] Optionally, the top beam 42 of the top cover 40 is provided with a lock seat 44. A locking bar device 41 extending along the container height direction DH is provided on the wall panel assembly 20 and / or door assembly 30, the upper end of which can be locked with the lock seat 44. The locking bar device 41 enhances the connection strength between the wall panel assembly 20, the door assembly 30, and the top cover 40. Optionally, the locking bar device 41 includes a locking bar, which may be a telescopic bar structure. The locking bar is movably connected along the height direction DH to one of the side wall, side door 31, end wall, and end door 32. The top end of the locking bar is provided with a lock head that can cooperate with the lock seat 44 of the top cover 40.
[0048] The top cover 40 can be connected to the aforementioned wall panel assembly 20 or door assembly 30. In this solution, the opening method of the top cover 40 can be at least one of pivoting, sliding, or detachable to adapt to different usage scenarios. Specifically, the pivoting connection is achieved through a hinge on one side of the top cover 40, allowing the top cover 40 to be flipped upwards and opened. The sliding connection is achieved through a guide rail system on the top of the housing, allowing the top cover 40 to slide longitudinally along the housing; the detachable connection is achieved through a quick-locking device, allowing the top cover 40 to be completely removed from the housing. Optionally, one side of the top cover 40 is hinged to the top of one side of the wall panel assembly 20 via a hinge, and the other side of the top cover 40 is locked to the top of the other side of the wall panel assembly 20 via a locking rod device 41.
[0049] Optionally, the enclosure also includes a securing device 43, which is a retractable strap or chain, one end of which is fixed to the wall panel assembly 20 or the base frame 10. When the top cover 40 is closed, the free end of the securing device 43 hooks onto the top beam 42 of the top cover 40, securing it in the closed position. This provides auxiliary fixation for the top cover 40 in addition to the main locking mechanism, further enhancing the stability and safety of the top cover during transport. The strap or chain can be retracted onto a dedicated reel for easy storage and use. The top beam 42 provides a reliable anchor point for securing the device.
[0050] The following is combined with Figure 1 , Figures 7 to 9The support frame 12 of this solution is described in detail below. The support frame 12 includes a support plate 13 and a column 14. The support plate 13 is hinged to the base frame 10 via a first pivot 15, allowing the support plate 13 to rotate around the hinge axis. The column 14 is hinged to the central area of the support plate 13 via a second pivot 16, allowing the column 14 to fold relative to the support plate 13. When the support frame 12 is in the upright position, the column 14 unfolds relative to the support plate 13, with its free end engaging with the base frame 10. At this time, the support plate 13 forms an inclined support surface that matches the outer contour of the rolled goods 60. When the support frame 12 is in the folded position, the column 14 and the support plate 13 overlap, and the entire structure is folded up to be flush with the floor 11. This hinged design enables the rapid conversion of the support frame 12 and ensures structural stability and reliability.
[0051] Optionally, the width of the column 14 is smaller than the width of the support plate 13. When the bracket 12 is in the folded position, the column 14 overlaps and folds with the support plate 13, and the column 14 can be stored inside the support plate 13.
[0052] Optionally, the base frame 10 is provided with a recess 17, in which the support plate 13 and the column 14 are at least partially accommodated when the support 12 is in the folded position. The recess 17 is a groove structure on the floor 11 of the base frame 10, the depth of which matches the thickness of the folded support 12, ensuring that the folded support 12 is flush with the surface of the floor 11, forming a truly flat bearing surface. The recess 17 also serves to position and protect the folded support 12, preventing it from moving during transportation.
[0053] Optionally, a limiting block 18 is provided within the recess 17. When the support 12 is in the upright position, the free end of the column 14 abuts against the limiting block 18. The limiting block 18 is a stop structure fixed within the recess 17, which can effectively restrict the column 14 from sliding along the plane of the floor 11, ensuring the stability of the support 12 in the upright position and preventing displacement under the weight of the goods. The limiting block 18 can be made of rubber or metal, serving both a limiting function and a shock-absorbing function.
[0054] Based on the above embodiment, the supports 12 are arranged in pairs, with two supports 12 in each pair arranged symmetrically opposite each other on the base frame 10, jointly supporting a roll of cargo 60. This paired symmetrical arrangement ensures that the weight of the roll of cargo 60 is evenly distributed on the base frame 10, maintaining cargo balance and preventing uneven loading. The number of pairs of supports 12 can be set according to the container length and cargo size to transport multiple rolls of cargo 60 simultaneously.
[0055] Optionally, the support frame 12 is arranged along the length direction (DL) or the width direction (DW) to adapt to the loading direction of the rolled cargo 60. When the axis of the rolled cargo 60 is parallel to the length direction of the container, the support frame 12 is arranged along the width direction of the container; when the axis of the rolled cargo 60 is parallel to the width direction of the container, the support frame 12 is arranged along the length direction of the container. This flexibility allows the container to accommodate rolled cargo 60 of different sizes and orientations, improving its applicability. The arrangement direction of the support frame 12 can be achieved by adjusting the connection method between the support frame 12 and the underframe 10.
[0056] In this solution, when transporting rolled goods 60, the support 12 is first moved from the folded position to the upright position. Specifically, the support plate 13 is rotated around the pivot to an inclined position, and then the column 14 is unfolded so that its free end engages with the base frame 10. The rolled goods 60 are then hoisted onto the saddle-shaped support. The top cover 40 and door assembly 30 are closed for transport. When loading and unloading goods, the top cover 40 and the corresponding side door 31 / end door 32 are opened according to the size of the goods and the loading and unloading requirements, forming a large, interconnected loading and unloading port, and loading and unloading equipment is used for operation. When transporting ordinary goods, the support 12 is moved to the folded position, and the support plate 13 and column 14 are stored in the recess 17, forming a flat bearing surface.
[0057] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings and several specific embodiments.
[0058] Example 1 refer to Figure 1 , Figure 2 and Figure 3 The container base frame 10 is equipped with multiple sets of supports 12, each set of supports 12 is arranged at intervals, and the spacing is designed according to the standard coil steel size. The supports 12 can be erected to form saddle-shaped supports along the width of the container to support rolled goods 60; or they can be folded into a flat state to load general cargo.
[0059] One side of the container is a standard side wall 21, used to enhance the container's strength; the other side is a side door 31, which is connected to the front wall 22 and the rear wall 22 via hinges, and the side door 31 can pivot around the hinges. Optionally, the side door 31 is a folding door to accommodate the longer length of the container and to achieve more flexible opening.
[0060] The top of the enclosure is an openable top cover 40, which is fixed to the enclosure by a locking device. The side wall 21 is provided with a locking rod device 41, which is movably connected to the side wall 21 along the height direction DH, and the lock head at the top of the locking rod is engaged with the lock seat 44 of the top cover 40.
[0061] After the side door 31 and the top cover 40 are opened, the first opening 51 and the second opening 52 are connected, providing ample space for the lateral loading and hoisting of the rolled goods 60.
[0062] The base frame 10 has several downward recesses and supports 12 on the floor 11 along the length of the container. The recesses are equipped with the pivots of the supports 12 and the limiting blocks 18.
[0063] The support 12 is in the shape of an "A" and includes a support plate 13 and a column 14. The end of the support plate 13 can pivot around the first pivot 15, the middle of the support plate 13 is connected to the second pivot 16, and one end of the column 14 can pivot around the second pivot 16.
[0064] When the support 12 needs to be erected, the operator first rotates the support plate 13 upward around the pivot of the support 12 to an inclined position, and then rotates the column 14 around the second pivot 16 to unfold it, so that the free end of the column 14 is placed in the recess. The other end of the column 14 is restricted to sliding in the recess by a limiting block 18, which is a stop welded in the recess and can effectively prevent the column 14 from shifting under the pressure of the cargo.
[0065] When the bracket 12 needs to be stored, first rotate the column 14 to fit against the support plate 13, and then rotate the support plate 13 downward to a horizontal position. After storage, the bracket 12 is flush with the upper surface of the floor 11, ensuring that the bottom surface is completely flat when loading ordinary goods.
[0066] Example 2 refer to Figure 4 The main difference between this embodiment and Embodiment 1 lies in the connection method of the side door 31.
[0067] The container has one or more detachable side doors 31, which are detachably connected to the container by means of pins, screws, clamps, locking rods, etc. The detachable side doors 31 are designed to fold up or down, or can be directly removed. When it is necessary to fully open the side, the side door 31 can be completely removed, which facilitates the loading and unloading of oversized or specially shaped goods.
[0068] Example 3 refer to Figure 5 This embodiment provides an implementation method with doors opening on both sides.
[0069] The container is equipped with openable side doors 31 on both sides. The two side doors 31 can be opened independently or simultaneously. After the side doors 31 and the top cover 40 are opened or removed, there are no other structures on the top and sides of the container. This fully open design provides great operational flexibility, allowing goods to be hoisted from either side of the container, making it particularly suitable for complex working conditions that require loading and unloading operations from multiple directions.
[0070] Compared with traditional frame containers, this embodiment provides the same convenient loading and unloading functions while avoiding the cumbersome operation of tarpaulin covering, and has better cargo protection performance and operational safety.
[0071] Example 4 refer to Figure 6 This embodiment provides an implementation method for end-opening doors.
[0072] The supports 12 of the container base frame 10 are arranged along the length of the container. This arrangement is suitable for loading rolled cargo 60 with its axial direction parallel to the width direction DW of the container. Rolled cargo 60 can be loaded along the length direction DL. The sides are fixed sidewalls 21, and the top is an openable top cover 40.
[0073] The rear end of the container is not equipped with a transverse top beam, forming a completely open upper edge. The end wall 22 without a top beam is equipped with an openable door. After the door and the top cover 40 are opened, the first opening 51 at the top connects with the third opening 53 at the end, which facilitates the entry and exit of heavy goods or rolled goods 60 from the end.
[0074] The box is equipped with a binding device 43 for securing the top cover 40 to the top of the box. The binding device 43 is a retractable nylon strap or chain, with one end fixed to the inside of the box and the free end having a hook-like component that can connect to the connecting member on the top beam 43 of the top cover 40, thereby reliably securing the top cover 40 to the box and ensuring that it remains tightly closed during transportation.
[0075] The top cover 40 is equipped with a top beam 42. In addition to providing structural reinforcement, the top beam 42 can also serve as a guide and protection device for hoisting operations, preventing the hoisting equipment from directly contacting the edge of the box.
