Description

Technical Field

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

[0002] When bulk cargo containers are used to transport bulk goods such as grain, coal, and ore, the dust from the cargo itself often pollutes the environment. During transport, there is also a possibility of leakage or falling cargo, which could endanger the lives and property of others.

[0003] To ensure the sealed transport of bulk cargo containers, the industry typically uses a top wall covering the top of the container. For ease of loading and unloading, and for accessing and exiting the container, the top wall is equipped with perforations. Bulk cargo containers also include perforation covers for opening or closing these perforations.

[0004] However, when it is necessary to operate the top cover to open or close the top hole, workers need to climb to the top of the box to operate the top cover, which is unsafe and inconvenient.

[0005] Therefore, this utility model provides a container to at least partially solve the above-mentioned problems. Utility Model Content

However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0042] The preferred embodiments of this utility model 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.

[0043] In this document, ordinal numbers such as “first” and “second” used in this invention are merely identifiers and do not have any other meaning, such as a specific order.

[0044] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0045] This utility model provides a container. The container can be a bulk cargo container used for transporting bulk goods such as grain, coal, and ore. The container's drive assembly 160 can drive the top cover 120 to move, thereby opening or closing the top opening 116.

[0046] like Figures 1 to 4 As shown, the container includes a container body 110. The container body 110 includes a top wall 111, vertical walls 112, a base frame (not shown), and end doors 115. Vertical walls 112 include end walls 113 and side walls 114. The top wall 111, end walls 113, side walls 114, end doors 115, and base frame form a generally rectangular parallelepiped structure. The top wall 111 has a top opening 116. Container body 110 can be accessed or unloaded, or bulk cargo can be loaded or unloaded, through the top opening 116.

[0047] The container also includes a top cover 120. The top cover 120 is movably connected to the top wall 111. Thus, the top cover 120 can move between a closed position and an open position. Figure 1 , Figure 2 and Figure 4 As shown, when the top hole cover 120 is in the closed position, the top hole cover 120 covers the top hole 116.

[0048] like Figure 3 As shown, when the top cover 120 is in the open position, the top cover 120 is completely separated from the top wall 111. At this time, the container 110 can be entered or exited, or bulk goods can be loaded or unloaded, through the top hole 116.

[0049] like Figure 2 and Figure 3 As shown, the container also includes a first link 130 and a second link 140. The first end 133 of the first link is rotatably connected to the lower end of the top cover 120 via a first top pivot. The second end of the first link 130 is rotatably disposed inside the container body 110 via a first pivot 150. The first pivot 150 is fixedly connected to the first link 130 to enable rotation of the first link 130.

[0050] The first end 141 of the second link is rotatably connected to the lower end of the top cover 120 via a second top pivot. The second end of the second link 140 is rotatably disposed inside the housing 110 via a second pivot 151.

[0051] The first link 130, the second link 140, the top cover 120, and the housing 110 constitute a four-bar linkage. While the first link 130 rotates about the axis of the first pivot 150, the second link 140 rotates about the axis of the second pivot 151. At this time, the action of the first link 130 and the second link 140 on the top cover 120 causes the top cover 120 to translate, thereby moving it between the open and closed positions. Thus, by rotating the first link 130 about the axis of the first pivot 150, or by rotating the second link 140 about the axis of the second pivot 151, the top cover 120 can be moved between the closed and open positions.

[0052] like Figure 4 As shown, the container also includes a transmission assembly 192. The transmission assembly 192 extends vertically. The upper end of the transmission assembly 192 is connected to a first pivot shaft 150, enabling it to rotate. Thus, the transmission assembly 192 drives a first connecting rod 130 to rotate about the axis of the first pivot shaft 150 via the first pivot shaft 150, thereby driving a second connecting rod 140 to rotate about the axis of the second pivot shaft 151, and consequently moving the top cover 120 between an open position and a closed position.

[0053] The lower end of the transmission assembly 192 extends to the lower end of the housing. The lower end of the transmission assembly 192 is used to connect to the drive assembly 160 described later.

[0054] like Figure 4 As shown, the container also includes a drive assembly 160. The drive assembly 160 is connected to the lower end of the transmission assembly 192 to drive the transmission assembly 192 to rotate, thereby causing the first link 130 to rotate about the axis of the first pivot shaft 150.

[0055] In this embodiment, the operator can operate the drive assembly 160 at the bottom of the box to drive the first connecting rod 130 to rotate around the axis of the first pivot shaft 150 via the transmission assembly 192, thereby moving the top hole cover 120 between the open and closed positions. This eliminates the need for the operator to climb to the top of the box 110 to move the top hole cover 120. Moving the top hole cover 120 is safe, convenient, requires less work intensity, and is highly efficient.

[0056] Alternatively, please refer to Figure 2 and Figure 3 The second connecting rod 140 is a straight rod. Therefore, the structure of the second connecting rod 140 is simple. The first connecting rod 130 is formed by bending a straight rod. The first connecting rod 130 includes a first rod segment 131 and a second rod segment 132. The length direction of the first rod segment 131 and the length direction of the second rod segment 132 form an angle. One end of the first rod segment 131 is rotatably connected to the lower end of the top hole cover 120 via a first top pivot. The other end of the first rod segment 131 is connected to one end of the second rod segment 132. The other end of the second rod segment 132 is rotatably disposed within the housing 110 via a first pivot 150. Therefore, the top hole cover 120 in the open position allows for a greater degree of opening of the top hole 116.

[0057] It is understood that, in the embodiment not shown, the first link may also be a straight rod. The second link includes a first segment and a second segment.

[0058] Optionally, along the height direction of the container body 110, a first pivot shaft 150 and a second pivot shaft 151 are spaced apart. The height of the second pivot shaft 151 is higher than the height of the first pivot shaft 150. Thus, the container structure is simple.

[0059] Please refer to Figures 1 to 4The axial directions of the first pivot shaft 150, the first top pivot shaft, the second pivot shaft 151, and the second top pivot shaft are all parallel to the length direction of the housing 110. Along the width direction of the housing 110, the first end 133 of the first connecting rod and the first end 141 of the second connecting rod are spaced apart. Along the width direction of the housing 110, the minimum distance between the first end 133 of the first connecting rod and the first end 141 of the second connecting rod is greater than half the size of the top cover 120. This allows for more stable translation of the top cover 120.

[0060] Please refer to Figures 2 to 4 Each top cover 120 can be connected to two sets of linkage assemblies. Each set of linkage assemblies includes a first link 130 and a second link 140. The two sets of linkage assemblies are spaced apart along the length of the housing 110. This provides more stable support for the top cover 120.

[0061] Optionally, such as Figure 4 As shown, the first pivot 150 extends to the end wall 113. The first pivot 150 is rotatably inserted through the end wall 113. Thus, the vertical wall 112 can support the first pivot 150. The container has a simple structure.

[0062] Both the drive assembly 160 and the transmission assembly 192 are connected to the end wall 113. Both the drive assembly 160 and the transmission assembly 192 are located outside the housing 110. This increases the internal space of the housing 110. Furthermore, it facilitates the operation or maintenance of the drive assembly 160.

[0063] The second pivot 151 extends to the end wall 113. The second pivot 151 is rotatably inserted through the end wall 113. The second pivot 151 is fixedly connected to the second link 140 so as to rotate together with the second link 140. Thus, the end wall 113 can support the second pivot 151, simplifying the structure of the container.

[0064] It is understood that, in embodiments not shown, the second pivot axis may also rotate relative to the second link.

[0065] For further information, please continue to refer to [link / reference]. Figure 4 The container also includes bearings 191. A first pivot shaft 150 is connected to an end wall 113 via a bearing 191. A second pivot shaft 151 is connected to an end wall 113 via another bearing 191. Thus, the first pivot shaft 150 and the second pivot shaft 151 can rotate freely.

[0066] like Figure 4As shown, the transmission assembly 192 also includes a torque-increasing gear train 170. The torque-increasing gear train 170 includes a gear set, an input end, and an output end. Thus, when torque is applied at the input end, a larger torque can be output at the output end. The torque-increasing gear train 170 is located outside the housing 110. The torque-increasing gear train 170 is connected to the end wall 113. The output end of the torque-increasing gear train 170 is connected to the first pivot shaft 150. The input end of the torque-increasing gear train 170 is connected to the drive assembly 160. Therefore, the drive assembly 160 can drive the first pivot shaft 150 to rotate with a relatively small torque output.

[0067] Please continue to refer to this. Figure 4 The first pivot shaft 150 is located at the top of the housing 110. The torque-increasing gear train 170 is located at the top of the housing. The drive assembly 160 is located at the bottom of the housing 110. The transmission assembly 192 also includes a transmission flexible element 180, a first wheel, and a second wheel. The transmission flexible element 180, the first wheel, and the second wheel are all located outside the housing. The transmission flexible element 180 extends vertically. The first wheel is connected to the input end of the torque-increasing gear train 170, and then connected to the first pivot shaft 150 through the torque-increasing gear train 170. The second wheel is connected to the drive assembly 160. The transmission flexible element 180 connects the first wheel and the second wheel. Thus, by operating the drive assembly 160 at the bottom of the housing 110, the second wheel can be rotated, thereby driving the first wheel to rotate through the transmission flexible element 180, which in turn drives the first pivot shaft 150 to rotate through the torque-increasing gear train 170, facilitating operation.

[0068] Furthermore, the flexible transmission component 180 can be a synchronous belt, V-belt, flat belt, rope, or chain. This facilitates the selection of the flexible transmission component 180.

[0069] Optionally, the drive assembly 160 may include a rotatable operating handle (not shown). The operating handle is detachably connected to the second wheel to drive the second wheel to rotate. Thus, manually turning the operating handle can drive the first pivot shaft 150 to rotate, making operation convenient.

[0070] The drive assembly 160 is provided with a locking component. The locking component may be a locking pin. When the top cover 120 is in the open or closed position, the locking pin passes through the operating handle and the housing 110 to lock the operating handle, thereby preventing the first pivot shaft 150 from rotating.

[0071] It is understood that, in embodiments not shown, the drive component is a drive motor or an internal combustion engine.

[0072] It is understood that, in embodiments not shown, the axial directions of the first pivot shaft, the first top pivot shaft, the second pivot shaft, and the second top pivot shaft are all parallel to the width direction of the housing. Along the length direction of the housing, the minimum distance between the first end of the first link and the first end of the second link is greater than half the size of the top cover. The first pivot shaft passes through the side wall. The drive assembly and torque amplification assembly are disposed on the side wall.

[0073] Please continue to refer to this. Figure 4 The container also includes a seal 190. The seal 190 can be a sealing strip. The seal 190 is connected to a top cover 120. When the top cover 120 is in the closed position, it presses the seal 190 against the top wall 111. At this time, the seal 190 is located between the top cover 120 and the top wall 111 to seal the gap between them.

[0074] In one embodiment (not shown), the top wall may have multiple top openings, and the container may include top opening covers corresponding to each of the multiple top openings. The top opening covers are used to cover the corresponding top openings. The container may include a first pivot shaft and a second pivot shaft. Each top opening cover is connected to two first links and two second links, respectively. All the first links are connected to a first pivot shaft, and all the second links are connected to a second pivot shaft.

[0075] It is understood that, in another embodiment (not shown), the container also includes a plurality of first pivot shafts corresponding one-to-one with the plurality of top cover. The container also includes a plurality of second pivot shafts corresponding one-to-one with the plurality of top cover. Each top cover is connected to its corresponding first pivot shaft via two first links. Each top cover is connected to its corresponding second pivot shaft via two second links.
