Abstract

This application discloses a container. The container includes a body pivot shaft, a container body, a top cover pivot shaft, and two top covers. The container body includes two sub-containers, the tops of the inner ends of the two sub-containers are pivotally connected via the body pivot shaft, so that the container body has a closed state with an open end and an open state with the lower parts of the inner ends of the two sub-containers spaced apart. The axial direction of the top cover pivot shaft is parallel to the axial direction of the body pivot shaft, and the top cover pivot shaft is located directly above the body pivot shaft. The two top covers and the two sub-containers correspond one-to-one, and the top cover is removably connected to the top of the corresponding sub-container to close the top opening. The ends of the two top covers that are close to each other are pivotally connected via the top cover pivot shaft. Thus, when the container body changes from a closed state to an open state to unload bulk cargo, the top cover always closes the top opening of the corresponding sub-container, which can minimize the dust generated during unloading.

Technical Field

[0001] This application relates to the field of containers, and more specifically to containers. Background Technology

[0002] Resource-based cargoes (bulk cargo, such as coal, mineral powder, etc.) are transported via bulk cargo containers. Some bulk cargo containers consist of two sub-containers. The inner ends of the sub-containers have end openings. The tops of the sub-containers have top openings. The tops of the inner ends of the two sub-containers are pivotally connected. Thus, when it is necessary to unload the bulk cargo from the container, by moving the bottoms of the inner ends of the two sub-containers away from each other, the bulk cargo can be unloaded through the end openings.

[0003] However, when unloading bulk cargo, the top opening of the sub-container generates a large amount of dust, polluting the environment.

[0004] Therefore, this application provides a container to at least partially solve the above-mentioned problems. Summary of the Invention

[0077] The preferred embodiments of this application will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0078] In this document, ordinal numbers such as “first” and “second” used in this application are merely identifiers and do not have any other meaning, such as a specific order.

[0079] To fully understand the embodiments of this application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, other embodiments may be available in addition to these detailed descriptions.

[0080] First Implementation Method

[0081] This application provides a container. The container can be used to transport bulk cargo. The bottom of the container body 120 can be opened to unload goods inside the body 120. The top of the body 120 is removably covered with a top cover 140. This reduces dust generation during unloading of bulk cargo.

[0082] Please refer to Figures 1 to 12 The container includes a body pivot 110 and a body 120. Body 120 includes two sub-body sections. Each sub-body includes a base frame 127, an end wall 125, and two side walls 126. The base frame 127 is configured as a generally rectangular structure. Along the length of the base frame 127, the end wall 125 is connected to one end of the base frame 127. Along the width of the base frame 127, the side walls 126 are connected to the sides of the base frame 127. Thus, the base frame 127, the end wall 125, and the two side walls 126 are configured as a generally cuboid structure. Along the length of the sub-body, the end wall 125 is located at one end of the sub-body (example of the outer end). Along the length of the sub-body, the inner end of the sub-body away from the outer end has an end opening 123. The top of the sub-body has a top opening 124. The end opening 123 and the top opening 124 communicate with each other.

[0083] Please refer to Figures 1 to 3 and Figure 5 The axial direction of the housing pivot 110 is parallel to the width direction of the sub-housing. Along the length of the sub-housing, a through hole is provided at the top of the end of the side wall 126 furthest from the end wall 125. The housing pivot 110 passes through this through hole. This through hole is circular. Thus, the inner ends of the two sub-housings are pivotally connected via the housing pivot 110. In this way, both sub-housings can rotate about the housing pivot 110, allowing the housing 120 to have both a closed and an open state.

[0084] like Figure 2 , Figure 8 , Figure 9 and Figure 11 As shown, when the housing 120 is in the closed state, the inner edges of the two sub-housing units are completely connected to close the end openings 123 of the two sub-housing units. At this time, the two sub-housing units form a roughly rectangular parallelepiped structure.

[0085] like Figure 1 and Figure 10 As shown, when the container 120 is in the open state, there is a gap between the lower parts of the inner ends of the two sub-containers. In this way, the end openings 123 of the two sub-containers are open, and the bulk goods inside the container 120 can be unloaded through the end openings 123 of the sub-containers.

[0086] Please refer to Figure 1 , Figure 2 and Figure 6The container also includes a top cover pivot 130 and two top covers 140. The two top covers 140 are provided one-to-one with the two sub-containers. The top cover 140 is removably connected to the top of the corresponding sub-container to cover the top opening 124 of the corresponding sub-container.

[0087] The axial direction of the top cover pivot 130 is parallel to the axial direction of the housing pivot 110. The ends of the two top covers 140 that are close to each other are pivotally connected by the top cover pivot 130.

[0088] The top cover pivot 130 is located directly above the container pivot 110. Thus, during the transition between the open and closed states of the container, the top cover 140 and its corresponding sub-container rotate together. Similarly, during the unloading of bulk cargo from the closed to the open state of the container 120, the top cover 140 remains closed over the top opening 124 of the corresponding sub-container, minimizing dust generation during unloading.

[0089] For details, please continue to refer to [the website / information]. Figure 1 and Figure 2 The two top covers 140 include a first top cover 141 and a second top cover 142. The two sub-boxes include a first sub-box 121 and a second sub-box 122. The first top cover 141 and the first sub-box 121 are correspondingly disposed. The second top cover 142 and the second sub-box 122 are correspondingly disposed. The first top cover 141 is removably connected to the top of the first sub-box 121 to cover the top opening 124 of the first sub-box 121. The second top cover 142 is removably connected to the top of the second top cover 142 to cover the top opening 124 of the second sub-box 122.

[0090] When the first sub-box 121 rotates relative to the second sub-box 122 about the box pivot 110, the first sub-box 121 causes the first top cover 141 to rotate relative to the second top cover 142 about the top cover pivot 130. When the second sub-box 122 rotates relative to the first sub-box 121 about the box pivot 110, the second sub-box 122 causes the second top cover 142 to rotate relative to the first top cover 141 about the top cover pivot 130.

[0091] The top cover pivot 130 is positioned directly above the housing pivot 110, which minimizes the downward indentation at the connection point between the top cover 140 and the top cover pivot 130, thereby reducing water or material accumulation at the connection point.

[0092] It should be noted that when the two sub-boxes rotate relative to each other about the box pivot 110, the top cover, which closes to the top of the sub-box, is slidable relative to the sub-box along its length. A connecting portion (not shown) is provided at the inner end of the sub-box. The connecting portion connects to the end of the top cover corresponding to the sub-box near the box pivot, thereby preventing movement of the end of the top cover near the box pivot along the length of the sub-box. The connection between the connecting portion and the top cover is detachable. Thus, when it is necessary to remove the top cover to load or unload goods into the box, the connection between the top cover and the connecting portion can be disengaged to remove the top cover. For example, the connecting portion can be a connecting lug. The connecting lug has a through-hole. The top cover 140 is detachably provided with a connecting shaft (not shown) coaxial with the top cover pivot 130. The connecting shaft rotatably passes through the through-hole.

[0093] In this embodiment, when the container 120 is switched from the closed state to the open state, the top cover 140 keeps the top opening 124 of the corresponding sub-container closed during the unloading of bulk goods, which can minimize the dust generated during unloading.

[0094] Preferably, such as Figures 1 to 4 As shown, the container also includes a lifting assembly 150. The lifting assembly 150 is connected to the top of the sub-container. The lifting assembly 150 includes an end lifting assembly 151 and a middle lifting assembly 152. The end lifting assembly 151 is located on the side of the sub-container away from its inner end, at the center along the installation direction. The middle lifting assembly 152 is located on the side of the center near the container's pivot axis 110. The axial direction of the container's pivot axis 110 and the height direction of the sub-container are both perpendicular to the installation direction. Thus, the installation direction is parallel to the length direction of the sub-container.

[0095] like Figures 8 to 11 As shown, the lifting equipment 170 is connected to the end lifting assembly 151 and the middle lifting assembly 152 via flexible components (ropes or chains). The flexible component connected to the end lifting assembly 151 is the end flexible component 172. The flexible component connected to the middle lifting assembly 152 is the middle flexible component 171.

[0096] Please refer to Figures 8 to 10 When the enclosure 120 is in the closed state, the hoisting equipment 170 hoists the end hoisting assembly 151 via the end flexible member 172, thus changing the enclosure 120 from the closed state to the open state, and maintaining this open state. Please refer to... Figure 10 and Figure 11 As shown, when the enclosure 120 is in the open state, the hoisting equipment 170 hoists the central hoisting assembly 152 via the central flexible member 171, which can change the enclosure 120 from the open state to the closed state and keep it in the closed state. Therefore, the operation of putting the enclosure 120 into the open or closed state is simple.

[0097] More preferably, the end lifting assembly 151 is located at the outer end of the sub-box. The middle lifting assembly 152 is located at the box pivot 110. The middle lifting assembly 152 is connected to one of the two sub-boxes. This facilitates placing the box 120 in an open or closed state.

[0098] like Figures 1 to 3 As shown, there are multiple end-lifting assemblies 151. Some end-lifting assemblies 151 are connected to the top of the end wall 125 of the sub-box. Other end-lifting assemblies 151 are connected to the top of the side wall 126 of the sub-box.

[0099] Please refer to Figure 2 and Figure 4 The lifting assembly 150 includes a hook 153 and a limiting member 154. The hook 153 is connected to the outer side of the sub-box. The limiting member 154 is pivotally connected to the hook 153. Thus, the limiting member 154 is rotatable between a closed position and an open position.

[0100] When the limiting member 154 is in the closed position, one end of the limiting member 154 abuts against the free end of the hook portion of the hook member 153, thereby closing the opening of the hook member 153. When the limiting member 154 is in the open position, the limiting member 154 moves away from the free end of the hook portion of the hook member 153, thereby opening the opening of the hook member 153.

[0101] The end of the flexible member is constructed as a circumferentially closed annular structure. When the limiting member 154 is in the open position, the annular structure of the flexible member can be fitted onto the hook portion of the hook member 153 through the opening of the hook member 153. At this time, when the limiting member 154 is in the closed position, the flexible member can be prevented from detaching from the hook member 153.

[0102] More preferably, the opening of the hook member 153 faces downward. This allows the flexible member to be more easily connected to the hook portion.

[0103] More preferably, such as Figure 4 As shown, the lifting assembly 150 also includes a hook return spring 155. The hook return spring 155 may be a torsion spring. The hook return spring 155 is connected to the hook connector 153 and the limiting member 154. The hook return spring 155 is in a deformed state. The hook return spring 155 in the deformed state can apply a force to the limiting member 154. This force can move the limiting member 154 away from the open position. Thus, the limiting member 154, which has left the closed position, can automatically move to the closed position and remain in the closed position.

[0104] More preferably, the limiting member 154 is also provided with an operating part 157. The operator can hold the operating part 157 to rotate the limiting member 154. This facilitates the operation of the limiting member 154.

[0105] Preferably, please refer to Figure 2 , Figures 8 to 11 The container also includes a locking assembly 160. The locking assembly 160 includes a locking part 161 and a lock 162 connected to the lower end of the sub-container. When the container 120 is in the closed state, the lock 162 is detachably connected to the locking part 161 to lock the closed container 120. This prevents the container 120 from transitioning from the closed state to the open state.

[0106] like Figure 2 As shown, the end lifting assembly 151 includes an end slider 156. A hook 153 of the end lifting assembly 151 is connected to the end slider 156. The end slider 156 is connected to the top end of the side wall 126 of the sub-box. Along the height direction of the sub-box, the end slider 156 is movably disposed between an end sliding unhooked position and an end sliding hooked position. It can be understood that the end slider 156 can be connected to the side wall 126 of the sub-box via an elongated hole. The long axis of the elongated hole is parallel to the height direction of the sub-box to which the end slider 156 is connected. The end slider 156 can also be connected to the side wall 126 of the sub-box via a slide rail. The length direction of the slide rail is parallel to the height direction of the sub-box to which the end slider 156 is connected.

[0107] Please continue to refer to this. Figure 2 The end slider 156 is connected to the lock 162. Thus, as the end slider 156 moves along the height direction of the sub-box, it can drive the lock 162 to move. As the end slider 156 moves from the end sliding hook position to the end sliding unhooked position, the end slider 156 drives the lock 162 away from the locking part 161, thereby releasing the lock on the box 120 which is in the closed state.

[0108] like Figure 8 and Figure 11 As shown, after the end flexible member 172 is connected to the hook member 153 connected to the end sliding member 156, the hook member 153 is lifted upwards, causing the end sliding member 156, which is in the end sliding hook position, to move upwards to the end sliding unhooked position. At this time, the lock 162 disengages from the locking part 161, thereby releasing the lock on the closed box 120. In this way, the two sub-boxes can rotate relative to each other about the box pivot axis 110. The hook member 153 is lifted upwards again. At this time, the hook member 153 lifts the outer end of the sub-boxes through the end sliding member 156, causing the two sub-boxes to rotate relative to each other, thereby changing the box 120 from the closed state to the open state. Thus, the end sliding member 156 and the lock 162 are linked, and the operation of changing the box 120 from the closed state to the open state can simultaneously release the lock on the closed box 120, making the operation simple.

[0109] The end slider 156 is movably connected to the sub-box body along the height direction of the sub-box body between the end sliding unhooking position and the end sliding hooking position. Therefore, there is no need to set up a corresponding structure to change the direction of force, and the structure of the box body 120 is simple.

[0110] like Figure 2 As shown, the locking part 161 is constructed as a locking pin. The locking pin is connected to the side wall 126 of the first sub-box 121 and protrudes to the outside of the side wall 126 of the first sub-box 121. The end slider 156 is connected to the second sub-box 122. The lock 162 includes a hook 163. The hook 163 is located on the outside of the second sub-box 122 away from the center of the second sub-box 122. The head end of the hook 163 is provided with a hook head 164. The opening of the hook head 164 faces upward. The hook head 164 is constructed in an arc shape. The hook head 164 is used to hook the locking pin from bottom to top. The tail end 166 of the hook 163 away from the hook head 164 is pivotally connected to the end slider 156. In this way, the end slider 156, which moves along the height direction of the second sub-box 122, can drive the tail end 166 of the hook 163 to move along the height direction of the second sub-box 122. The hook rod 163 is provided with a pivot part 165. The pivot part 165 is located between the tail end 166 and the hook head 164. The hook rod 163 is rotatably connected to the side wall 126 of the second sub-box 122 via the pivot part 165.

[0111] Please continue to refer to this. Figure 2 The lock 162 also includes an elastic element 167. The elastic element 167 may be a cylindrical spring. The elastic element 167 is located on the side of the hook 163 away from the lower end of the second sub-box 122. One end of the elastic element 167 is connected to the portion of the hook 163 located between the pivot 165 and the hook head 164. The other end of the elastic element 167 is connected to the second sub-box 122. The elastic element 167 is in a stretched state, enabling it to apply a force (tension) to the hook 163 to engage the hook head 164 with the locking pin. Thus, when the hook head 164 disengages from the locking pin, the elastic element 167 enables the hook 163 to rotate to engage with the locking pin.

[0112] like Figures 8 to 11 As shown, the hoisting equipment 170 is connected to the end hoisting assembly 151 via the end flexible member 172. The hoisting equipment 170 is connected to the middle hoisting assembly 152 via the middle flexible member 171.

[0113] like Figure 8 and Figure 9As shown, when the housing 120 is in the closed state, the lifting equipment 170 applies an upward force to the end flexible member 172 to keep it taut. Thus, the lifting equipment 170 connects the end flexible member 172 to the hook 153 that lifts upwards and the end sliding member 156, thereby moving the end sliding member 156 from the end sliding hook position to the end sliding unhooked position. During this process, the hook rod 163 rotates counterclockwise around the pivot 165 to disengage the hook head 164 from the locking pin, thereby releasing the lock on the closed housing 120. During this process, the lifting equipment 170 exerts no force on the middle flexible member 171, leaving it in a loose state.

[0114] like Figure 10 As shown, as the hook 153 continues to be lifted upwards, the hook 153 lifts the outer end of the sub-box via the end sliding member 156, causing the two sub-boxes to rotate relative to each other, thereby changing the box 120 from a closed state to an open state. At this time, the lifting equipment 170 can lift other end lifting components 151. During this process, the end flexible member 172 is in a taut state, and the lifting equipment 170 exerts no force on the middle flexible member 171, leaving the middle flexible member 171 in a loose state.

[0115] like Figure 10 and Figure 11 As shown, when the housing 120 is in the open state, if it is necessary to close the housing 120, the lifting equipment 170 applies an upward force to the central flexible member 171 to flex it. In this way, the lifting equipment 170 lifts the central lifting assembly 152 upwards via the central flexible member 171. The lifting equipment 170 then releases the force on the end flexible members 172, allowing them to relax.

[0116] When the lifting equipment 170 releases the force on the end flexible member 172, the end sliding member 156 moves downward under its own weight, causing the hook rod 163 to rotate clockwise around the pivot 165, thereby rotating the hook head 164 to a position where it can engage the locking pin. During this process, the tension of the elastic member 167 also causes the hook rod 163 to rotate clockwise around the pivot 165, thereby rotating the hook head 164 to a position where it can engage the locking pin.

[0117] The hoisting equipment 170 lifts the middle part of the housing 120 via the central flexible component 171, thereby changing the housing 120 from an open state to a closed state. When the housing 120 is about to be switched to the closed state, the outer arc surface of the hook head 164 of the hook rod 163, away from the tail end 166 of the hook rod 163, contacts the locking pin. At this time, under the action of the locking pin on the hook head 164, the hook rod 163 rotates counterclockwise around the pivot 165, causing the locking pin to slide relative to the hook head 164 along the outer arc surface of the hook head 164 into the opening of the hook head 164. Thus, the hook head 164 can engage the locking pin.

[0118] Preferably, such as Figure 12 As shown, the free end of the arc-shaped part is provided with a guide surface 168. When the housing 120 is about to be switched to the closed state, the locking pin slides along the guide surface 168. At this time, under the action of the guide surface 168, the locking pin slides along the guide surface 168 into the opening of the hook head 164. This facilitates operation.

[0119] The elastic element 167 is provided so that the hook 164 can hook onto the locking pin and remain hooked onto the locking pin.

[0120] It is understandable that the timing of applying an upward force to the middle flexible component and releasing the force to the end flexible component can be controlled so that when the box is in the closed position, the hook rod rotates so that the hook head engages with the locking pin, thus preventing the locking pin and the hook head from colliding.

[0121] Preferably, the container also includes a body seal (not shown). The body seal is connected to one of the two sub-body compartments. When the container 120 is in the closed state, one sub-body compartment presses the body seal against the other sub-body compartment to seal the gap between the two sub-body compartments. This prevents leakage.

[0122] The hook 153 extends to the upper side of the sub-box. A portion of the top cover 140 at the end furthest from the box pivot 110 is recessed toward the box pivot 110 to form a clearance notch 144. Along the width direction of the sub-box, the clearance notch 144 is located at the lifting assembly 150 connected to the end wall 125 of the sub-box. Thus, when the box changes from an open state to a closed state, the clearance notch 144 can avoid the lifting assembly 150 connected to the end wall 125 of the sub-box.

[0123] like Figure 7 As shown, the top cover 140 is also provided with a top cover seal 180. When the top cover 140 closes to the corresponding sub-box, the top cover 140 presses the top cover seal 180 against the top of the corresponding sub-box to seal the gap between the top cover 140 and the corresponding sub-box.

[0124] like Figure 1As shown, the top cover 140 is provided with a top cover fork groove 143. The bottom end of the sub-box is provided with a box fork groove 128. This facilitates the movement of the sub-box and the top cover 140.

[0125] Second Implementation Method

[0126] In the second implementation method, please refer to Figure 13 The elastic element 267 is located on the side of the hook rod 163 near the bottom end of the second sub-box. One end of the elastic element 267 is connected to the portion of the hook rod 163 located between the pivot portion 265 and the tail end 266. The other end of the elastic element 267 is connected to the sub-box. The elastic element 267 is in a stretched state to apply tension to the hook rod 163.

[0127] The other settings of the second embodiment are largely the same as those of the first embodiment, and will not be described again here.

[0128] Third Implementation Method

[0129] like Figure 14 As shown, in the third embodiment, along the width direction of the sub-box, the box pivot 310 protrudes to the outer side of the side wall of the sub-box, away from the center of the sub-box, to form a central lifting assembly. Therefore, the structure of the central lifting assembly is simple.

[0130] The end lifting assembly 351 is constructed as a lifting shaft. The axial direction of the lifting shaft is perpendicular to the height direction of the sub-box to which it is connected. Along the axial direction of the lifting shaft, the lifting shaft protrudes to the outside of the sub-box to which it is connected. Thus, the structure of the end lifting assembly is simple.

[0131] The other settings of the third embodiment are largely the same as those of the first embodiment, and will not be described again here.

[0132] Fourth Implementation Method

[0133] like Figure 15 As shown, in the fourth embodiment, both sub-boxes are provided with locking parts 461. The locking part 461 is a locking plate. The locking plate is connected to the lower end of the side wall of the sub-box and is located on the outer side of the side wall. The locking part 461 is provided with a locking hole 462. The axial direction of the locking hole 462 of the locking part 461 is parallel to the height direction of the sub-box to which it is connected.

[0134] The lock includes a pin 464 and a flexible connector 468. When the housing is closed, two locking plates are arranged sequentially along the height of the housing. When the housing is closed, the locking holes 462 of the two locking plates are approximately coaxial. At this time, the pin 464 can be disengaged and passed through the two locking holes 462 to lock the housing in the closed state. The flexible connector 468 can be a rope or chain. A guide wheel (not shown) is provided on the second sub-housing to change the extension direction of the flexible connector 468. The guide wheel can be provided as needed. One end of the flexible connector 468 is connected to the pin 464. The other end of the flexible connector 468 is connected to an end slider 463. Thus, during the movement of the end slider 463 from the end sliding hook position to the end sliding unhooked position, the movement of the end slider 463 can drive the pin 464 to move via the flexible connector 468, causing the pin 464 to disengage from the locking hole 462, thereby releasing the lock on the closed housing. Therefore, the lock assembly has a simple structure.

[0135] The other settings of the fourth embodiment are largely the same as those of the first embodiment, and will not be described again here.

[0136] Fifth Implementation Method

[0137] like Figure 16 As shown, the locking assembly includes a James coupler 561. The James coupler 561 is a prior art James coupler for trains. The James coupler 561 includes a pin 564. The pin 564 is connected to an end slide member 563 via a flexible connector 568. Thus, the end slide member 563 can move the pin 564 upward via the flexible connector 568 to unlock the James coupler 561.
