[0134] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.
[0135] This utility model provides a wall structure for a shipping container.
[0136] Please see Figure 1 and Figure 2The container wall structure 100 includes a wall panel 110, an unloading door 120, a first locking assembly 130, and a second locking assembly 140. Specifically, the wall panel 110 has at least one unloading port 118 extending through the wall panel 110 along its thickness direction DT. The unloading port 118 is located in the lower middle portion of the wall panel 110 along its height direction DH. The unloading door 120 has a first side 121 and a second side 122 spaced along its width direction DW. The first side 121 is pivotally connected to the wall panel 110 between an open and closed position about a first axis extending in the vertical direction (or the height direction DH of the wall panel 110) to open and close the unloading port 118. The first locking assembly 130 is disposed between the wall panel 110 and the unloading door 120. The first locking assembly 130 is vertically disposed and connected to both the wall panel 110 and the unloading door 120. Both ends of the first locking assembly 130 extend vertically beyond the unloading gate 120. The second locking assembly 140 is disposed between the wall panel 110 and the second side 122. The second locking assembly 140 is connected to the wall panel 110 and the second side 122. It should be noted that when at least one of the first locking assembly 130 and the second locking assembly 140 is locked, the unloading gate 120 is confined to the closed position.
[0137] According to the container wall structure 100 of this scheme, by setting the first locking component 130 and the second locking component 140, the clamping force between the unloading door 120 and the wall panel 110 when the unloading door 120 is in the closed position can be dispersed, thereby suppressing the deformation of the unloading door 120 and facilitating the sealing between the unloading door 120 and the unloading port 118.
[0138] The following is an explanation of the aforementioned "lower middle part".
[0139] The discharge port 118 is generally located at the lower part of the wall panel 110, that is, along the height direction DH of the wall panel 110, not exceeding the position of 1 / 2 height dimension line of the wall panel 110; preferably, the discharge port 118 is located below the position of 1 / 3 height dimension line of the wall panel 110. In other words, the height of the top edge of the discharge port 118 does not exceed the position of 1 / 3 height dimension line of the wall panel 110.
[0140] Furthermore, in order to enable the unloading door 120 to pivot relative to the wall panel 110, a hinge 123 can be provided between the unloading door 120 and the wall panel 110 (see...). Figure 1 It is understood that hinge 123 generally includes a fixed part and a movable part. For example, the fixed part is connected to the wall panel 110, and the movable part is connected to the unloading door 120. The movable part can pivot relative to the fixed part about the first axis, thereby realizing the pivoting opening and closing of the unloading door 120.
[0141] Please continue reading. Figure 1 and Figure 2, the wall panel 110 includes a lower wall panel 112, and the lower wall panel 112 is located at the aforementioned "lower middle" position. The discharge opening 118 and the discharge door 120 are both provided on the lower wall panel 112.
[0142] The wall structure 100 of the container further includes a door frame assembly 150, and the door frame assembly 150 is provided around the discharge opening 118. Specifically, the door frame assembly 150 includes a discharge door lintel 151 and a threshold 152. The discharge door lintel 151 is arranged along the width direction DW of the wall panel 110. The discharge door lintel 151 is located above the discharge opening 118 and is connected to the lower wall panel 112. The threshold 152 is arranged along the width direction DW of the wall panel 110, and the threshold 152 is located below the discharge opening 118 and is connected to the lower wall panel 112. Among them, the discharge door 120 in the closed position is connected to the discharge door lintel 151 and the threshold 152. Further, the wall panel 110 further includes an upper wall panel 111, and the lower wall panel 112 is located below the upper wall panel 111. The discharge door lintel 151 is located between the upper wall panel 111 and the lower wall panel 112, and the discharge door lintel 151 is connected to the upper wall panel 111 and the lower wall panel 112, that is, the door frame assembly 150 is provided on the lower wall panel 112. Please refer to Figure 3 , in order to improve the connection strength of the components around the discharge opening 118, the wall structure 100 of the container further includes discharge opening columns 119, and the discharge opening columns 119 are arranged in the vertical direction and are located around the discharge opening 118. The discharge opening columns 119 are arranged in pairs, and the two discharge opening columns 119 in a pair are spaced along the width direction DW of the wall panel 110, and both ends of the discharge opening columns 119 are respectively connected to the discharge door lintel 151 and the threshold 152.
[0143] Now please refer to Figures 3 to 5 , the discharge door 120 includes a door body 124 and a strengthening member 125. Specifically, the door body 124 has a first surface 124a and a second surface 124b spaced along the thickness direction DT of the discharge door 120. When the discharge door 120 is in the closed position, along the thickness direction DT of the discharge door 120, the second surface 124b is closer to the lower wall panel 112 than the first surface 124a (see Figure 4 ). The strengthening member 125 is provided on the second surface 124b. It can be understood that the door body 124 is constructed as a box shape with an opening (see Figure 4 and Figure 8 ), and when the discharge door 120 is in the closed position, the opening faces the discharge opening 118. And, Figure 5 in, the strengthening member 125 is constructed as a substantially "day" - shaped frame structure.
[0144] Now please go back and refer to Figure 1The first locking assembly 130 is preferably constructed as a common locking bar assembly commonly used in containers. Specifically, the first locking assembly 130 includes a locking bar 131 and a locking seat 133. The locking bar 131 is arranged vertically, and each end of the locking bar 131 is provided with a locking head 132. The locking seat 133 is provided on the lintel 151 and the sill 152 of the unloading door. The locking seat 133 is correspondingly provided with the locking head 132. It should be noted that the locking bar 131 is pivotally connected to the unloading door 120 around the axis of the locking bar 131, and the locking head 132 can pivot with the locking bar 131. The locking head 132 is pivotally connected to the locking seat 133 between the unlocked position and the locked position. It is understood that the lock head 132, located in the locked position, is connected to the lock seat 133 to keep the unloading door 120 in the closed position; when the second locking assembly 140 is unlocked (i.e., in the unlocked state) and the lock head 132 is in the unlocked position, the unloading door 120 can pivot from the closed position to the open position. Furthermore, the first locking assembly 130 also includes a bracket 134, a limiting ring 135, a handle 136, and a handle seat 137. The bracket 134 is disposed on the unloading door 120 and is used to mount the locking rod 131 to the unloading door 120. The limiting ring 135 is located on the outer periphery of the locking rod 131 and is adapted to the bracket 134 to limit the vertical movement of the locking rod 131 relative to the bracket 134. The handle 136 is disposed on the outer periphery of the locking rod 131 and is pivotable relative to the locking rod 131, and the handle seat 137 is disposed on the unloading door 120 and is adapted to the handle 136. Handle 136 is used for the operator to pivot the locking lever 131. When the lock head 132 is in the locked position, handle 136 can be connected to handle seat 137 to further limit the pivoting of the locking lever 131. Preferably, along the width direction DW of the wall panel 110, the distance between the locking lever 131 and the first side 121 is greater than the distance between the locking lever 131 and the second side 122. In other words, when the unloading door 120 is in the closed position, along the width direction DW of the wall panel 110, the distance between the locking lever 131 and the hinge 123 is greater than the distance between the locking lever 131 and the second locking assembly 140.
[0145] Please see now Figure 4 and Figure 5The second locking assembly 140 includes a pressure plate 141, a limiting rod 143, and a locking member 144. Specifically, the pressure plate 141 is disposed on the discharge gate 120 and has a bayonet 142. The limiting rod 143 is disposed on the lower wall plate 112 and is movably connected to the bayonet 142 between a first position and a second position. The limiting rod 143 in the first position is connected to the bayonet 142, and the limiting rod 143 in the second position is separated from the bayonet 142. The locking member 144 is rotatably connected to the limiting rod 143 about its axis and can move with the limiting rod 143. The locking member 144 is used to abut against the pressure plate 141 so that the limiting rod 143 is held in the first position, thereby holding the discharge gate 120 in the closed position. For example, the limiting rod 143 is configured as a hinged bolt, and the locking member 144 is configured as a nut. It is understood that the outer diameter of the nut is larger than the diameter of the hole in the bayonet 142. One end of the pressure plate 141 is connected to the discharge gate 120, and the other end of the pressure plate 141 away from the discharge gate 120 is provided with the bayonet 142, which is, for example, U-shaped. One end of the hinge bolt is pivotally connected (or hinged) to the lower wall plate 112. The nut can be adjusted by turning it with a tool, moving it along the axis of the hinge bolt. Alternatively, a wing nut or other nut with an operating part can be used. When the discharge gate 120 is closed, the locking member 144 (nut) can be pressed down, pressing the pressure plate 141 to tighten the discharge gate 120. When the unloading gate 120 is opened, the locking member 144 (nut) moves upward, disengaging from the pressure plate 141. Then, an external force is applied to the limiting rod 143 (hinged bolt), causing it to rotate away from the unloading gate 120. The limiting rod 143 disengages from the latch 142 at the pressure plate 141, at which point the unloading gate 120 can be opened. Preferably, the number of second locking components 140 is at least two, and these at least two second locking components 140 are spaced apart along the height direction DH of the wall panel 110. Alternatively, please refer to... Figure 6 and Figure 7 A second locking assembly 240 is shown. The second locking assembly 240 is configured as a latching quick-opening mechanism. Specifically, the second locking assembly 240 includes an operating member 241, a snap-fit member 242, and a fixing base 243. The operating member 241 is disposed on the unloading gate 120 and is pivotally connected to the unloading gate 120. For example, the operating member 241 is connected to the unloading gate 120 via a mounting base 244, which is pivotally connected about a second axis extending in a vertical direction. The snap-fit member 242 is disposed on the operating member 241 and is movable following the operating member 241. The fixing base 243 is disposed on the lower wall panel 112 and has a snap-fit interface adapted to the snap-fit member 242. Figure 6 and Figure 7In the middle, the fixing seat 243 is installed on the discharge port column 119 at the lower wall plate 112. It should be noted that the snap-fit member 242 is configured to be adjustablely connected to the operating member 241 along the thickness direction DT of the discharge gate 120. For example Figure 6 In this design, the locking member 242 is constructed as a U-bolt. The locking member 242 can also be pivotally adjusted relative to the operating member 241 about a third axis extending vertically, allowing for precise connection of the locking member 242 to the fixed seat 243. When the locking member 242 is connected to the fixed seat 243 (e.g., via a U-bolt to the locking interface), the discharge gate 120 is confined to the closed position. The locking member 242 is adjustable, allowing for adjustment of the locking force between the locking member 242 and the fixed seat 243 to suit different usage requirements. Pulling the operating member 241 allows for easy engagement and disengagement of the locking member 242 from the fixed seat 243. Alternatively, the second locking assembly can be constructed as other existing locking mechanisms that enable rapid opening of the discharge gate 120.
[0146] It should be noted that when closing the unloading gate 120, the first locking component 130 should be locked first, followed by the second locking component 140 (or the second locking component 240). When opening the unloading gate 120, the second locking component 140 should be unlocked first, followed by the first locking component 130. If the second locking component 140 is unlocked last, the impact force of the cargo may cause the second locking component to be passively released during the unlocking process, which could easily lead to a safety accident.
[0147] Please see now Figure 1 , Figure 2 and Figure 9 To protect the unloading door 120 from external collision damage, the container wall structure 100 also includes a crash barrier 155. Specifically, the crash barrier 155 is disposed on the unloading door lintel 151 and the sill 152, and the crash barrier 155 and the unloading door 120 are located on the same side of the lower wall panel 112. It can be understood that when the unloading door 120 is in the closed position, the crash barrier 155 protrudes from the unloading door 120 along the thickness direction DT of the wall panel 110. As mentioned above, both ends of the single locking rod 131 are provided with lock heads 132, and the lock seats 133 must be correspondingly provided with the lock heads 132; that is, the first locking assembly 130 includes at least two lock seats 133. Among them, at least one lock seat 133 is disposed on the unloading door lintel 151, and at least one lock seat 133 is disposed on the sill 152. It should be noted that, since the unloading gate 120 overlaps the unloading gate lintel 151 and threshold 152 when closed, the installation position of the lock seat 133 needs to be raised if it is to connect with the unloading gate lintel 151 and threshold 152. For details, please refer to... Figure 2 The unloading gate lintel 151 is equipped with a mounting base 154. Figure 2 and Figure 9In this structure, the threshold 152 is designed to be concave at the top and convex at the bottom. In other words, at least the threshold 152, the mounting base 154, and the anti-collision member 155 together form a receiving cavity 158 for accommodating the unloading gate 120.
[0148] Please continue reading. Figure 1 , Figure 2 and Figure 9 Furthermore, the anti-collision member 155 includes a first anti-collision member 156 and / or a second anti-collision member 157. Preferably, the anti-collision member 155 includes a first anti-collision member 156 and a second anti-collision member 157. Specifically, the first anti-collision member 156 is disposed along the width direction DW of the wall panel 110, and is disposed on the lintel 151 of the unloading door. The first anti-collision members 156 are disposed in pairs, with the two pairs of first anti-collision members 156 spaced apart along the width direction of the wall panel 110. The second anti-collision member 157 is disposed along the width direction DW of the wall panel 110, and is disposed on the threshold 152. The second anti-collision members 157 are disposed in pairs, with the two pairs of second anti-collision members 157 spaced apart along the width direction DW of the wall panel 110. Figure 1 In this design, two pairs of first anti-collision members 155 are located on either side of the lock seat 133 on the lintel 151 of the unloading door (specifically, the mounting base 154 on the lintel 151 of the unloading door), and two pairs of second anti-collision members 157 are located on either side of the lock seat 133 on the sill 152. The anti-collision members 155 can be constructed as square tubing; that is, to avoid the installation position of the lock seat 133, both the first anti-collision members 156 and the second anti-collision members 157 are constructed as segmented designs. The second anti-collision members 157 protect the container wall structure 100 from impacts on the lock head 132 and lock seat 133 when the container is on the ground.
[0149] Please see now Figure 1 and Figure 2 As described above, the unloading door lintel 151 is located above the threshold 152. The container wall structure 100 also includes an unloading port surround 127 and a first seal 126. The unloading port surround 127 is disposed on the door frame assembly 150 and located around the unloading port 118. The first seal 126 is disposed on one of the unloading port surround 127 and the unloading door 120; when the unloading door 120 is in the closed position, the first seal 126 abuts against the other of the unloading port surround 127 and the unloading door 120. For example Figure 2 , Figure 4 and Figure 8In this configuration, a first seal 126 is disposed on the unloading gate 120, specifically on the second surface 124b of the unloading gate 120. A reinforcing member 125 and the gate body 124 enclose an installation area 129, where the first seal 126 is located. When the unloading gate 120 is in the closed position, the first seal 126 abuts against the unloading port surround 127. Further details can be found in the following section. Figure 10 and Figure 11 The container wall structure 200 also includes a second seal 128. The second seal 128 is disposed on one of the reinforcing member 125 and the door frame assembly 150; when the unloading door 120 is in the closed position, the first seal 126 abuts against the door frame assembly 150, and the second seal 128 abuts against the other of the reinforcing member 125 and the door frame assembly 150. For example, the second seal 128 is disposed on the door frame assembly 150, and when the unloading door 120 is in the closed position, the first seal 126 abuts against the unloading port surround 127 at the door frame assembly 150, and the second seal 128 abuts against the reinforcing member 125. Both the first seal 126 and the second seal 128 can be constructed as rubber strips.
[0150] It should be noted that by setting the first locking assembly 130 and the second locking assembly 140 at the unloading gate 120, a dual clamping force can be formed. When the container wall structure 100 (or container wall structure 200) is applied to a container, the impact of the container's internal pressure on the unloading gate 120 can be dispersed, significantly improving the reliability of the seal. Furthermore, by setting the first locking assembly 130 and the second locking assembly 140, the traditional single-point locking method is broken through, which can disperse the sealing clamping force, suppress the deformation of the unloading gate 120, significantly improve the reliability of the seal, and also reduce the wear of sealing components (such as rubber strips), extend their service life, and reduce maintenance costs.
[0151] Please return to the reference section. Figure 1 The container wall structure 100 (or container wall structure 200) also includes corner posts 113 and a top lintel 116. Specifically, the corner posts 113 are arranged vertically and located on the periphery of the wall panel 110. Each end of the corner post 113 has a top corner piece 114 and a bottom corner piece 115. The corner posts 113 are arranged in pairs, with the two pairs spaced apart along the width direction DW of the wall panel 110 and connected to the wall panel 110 respectively. The top lintel 116 is arranged along the width direction of the wall panel 110 and connected to the top corner piece 114 at both ends, connecting to the top of the wall panel 110. It can be understood that the sill 152 is arranged along the width direction DW of the wall panel 110 and connected to the bottom corner piece 115 at both ends, connecting to the bottom of the wall panel 110. The sill 152 has at least two downward-facing anti-collision grooves 153. Figure 1In the middle, the threshold 152 has two anti-collision grooves 153 respectively located near the bottom corner piece 115.
[0152] This utility model also provides a container (not shown).
[0153] The container includes a container body and the aforementioned container wall structure 100 (or container wall structure 200), the container wall structure being connected to the container body. Preferably, there is one unloading port 118, which communicates with the outside and the interior of the container body. The unloading port 118 is centered or substantially centered along the width direction DW of the wall panel 110. Furthermore, the container wall structure is located at the end of the container, and the thickness direction DT of the wall panel 110 is configured to correspond to the length direction DL of the container. There is one unloading door 120. Alternatively, there may be multiple unloading ports 118, and the container wall structure may also be located on the side of the container, with the thickness direction DT of the wall panel 110 corresponding to the width direction DW of the container.
[0154] Preferably, the container is constructed as a bulk cargo container. The container also has at least one entrance / exit communicating with the outside and the interior of the container, the entrance / exit being located on the top of the container. The container also includes at least one top cover located on the top of the container, the top cover being detachably connected to the container to open and close the entrance / exit.
[0155] Please see now Figure 1 and Figure 3 To facilitate the loading and unloading of bulk cargo, the container also includes a flow guide member 117, which is disposed inside the container body. The flow guide member 117 is connected to the container body and the container wall structure, and serves at least to guide material located inside the container body to the discharge port 118. Preferably, the flow guide members 117 are arranged in pairs, with the two pairs spaced apart and opposite each other along the width direction DW of the wall panel 110, and the discharge port 118 located between the two pairs of flow guide members 117. Preferably, the flow guide member 117 is constructed as a plate-like member, with its edges connected to the end wall, side wall, and floor of the container (i.e., the container body has a floor). The flow guide member 117, together with the end wall, side wall, and floor, forms an upward-pointing pyramidal structure to guide the material inside the container body. It is understood that the flow guide member 117 has an inclined flow guide surface.
[0156] Those skilled in the art will understand that the concept of the angle of repose is commonly found in the field of bulk container shipping. The angle of repose, also known as the angle of repose or angle of stacking, refers to the maximum angle between the free surface of a loose granular material pile and the horizontal plane (or the placement surface) in its natural stacking state. It is an important physical parameter for measuring the flowability of granular materials, reflecting the frictional characteristics and interactions between the material particles. Therefore, the angle between the aforementioned guiding surface and the placement surface generally differs for different types of materials. In this invention, when the plane containing the floor is tilted at a 45° angle relative to the placement surface (generally, the container is tilted at 45° for unloading), the angle between the guiding surface and the placement surface ranges from 35° to 45°. For example, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, and 45°. Preferably, the angle between the guiding surface and the placement surface ranges from 39° to 40°. It is understandable that the bottom edge of the aforementioned discharge port 118 is generally flush with the upper surface of the floor.
[0157] According to this utility model, the unloading door of the container, in addition to its ability to unlock quickly, is equipped with a first locking rod assembly to ensure sealing and operational safety. A reinforcing member is added to the unloading door to reduce deformation of the door body, and a second sealing element can be installed between the reinforcing member and the door frame assembly to further improve sealing performance. For a single unloading door, by optimizing the flow guiding member inside the container, unloading without residue can be achieved, and the angle of the flow guiding member can be customized and adjusted according to the characteristics of the cargo. For example, in the case of container transporting alumina, when the inclination angle of the plane where the ground is located relative to the placement surface is 45°, the angle between the flow guiding surface and the placement surface ranges from 30° to 35° (inclusive).
