Description

Container, especially container for transporting goods

Technical Field

The invention relates to the field of containers, in particular to a container.

Background

The container transportation in the logistics system becomes an important form of transportation modernization by virtue of the characteristics of high efficiency, convenience and safety, and is paid very extensive attention.

Conventional standard containers basically employ an end-opening door structure. The container with the end-opening door structure is inconvenient for unloading bulk cargos such as particles, powder and blocks (such as coal, ore, chemical fertilizer, bulk sugar, bean pulp, cement, alumina, stone and grain) which need to be directly boxed and transported.

In order to solve the problem of inconvenient loading and unloading of bulk cargo, in some existing containers for transporting the bulk cargo, the unloading door structure is a combination of a turnover door, a common pull door or a hinged door leaf and a lock rod, so that the unloading door is opened to occupy the space outside the container when the bulk cargo in the container is unloaded.

In addition, when bulk cargo is discharged from the container, the container needs to be turned or tilted, and thus the height of free fall of the bulk cargo is large, causing a large dust emission. And before discharging the bulk cargo in the container, the worker is required to operate the discharge door, so that the worker may be damaged by opening the discharge door.

To this end, the present invention provides a container to at least partially solve the above problems.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The following detailed description of preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

First embodiment

The invention provides a container. The container may be used for transporting bulk cargo. The container can discharge the bulk cargo from the lower part of the container.

As shown in fig. 1 to 5, the container includes a case 110. The case 110 includes a wall 111 and a top wall at an upper end of the case 110. Wall 111 includes side walls 112 and end walls 113. The wall 111 and the ceiling wall are configured into a substantially rectangular parallelepiped structure. The top wall has a top side beam 117 and a top end beam 118. The wall 111 and the ceiling wall are integrally formed at an upper portion of the case 110.

The lower portion of the case 110 forms a W-shaped structure. Thus, the W-shaped structure may increase the strength of the lower portion of the case 110.

The W-shaped structure has a first sloped wall 114. The first sloped wall 114 is connected to the side wall 112 by a later second sloped wall 116. The first inclined wall 114 is located on an inner side of the side wall 112 (a side of the side wall 112 close to the center of the case 110) in the first horizontal direction X. The first inclined wall 114 is inclined to the first horizontal direction X. The first inclined wall 114 is parallel to the second horizontal direction Y.

In the present embodiment, the first horizontal direction X is parallel to the width direction of the case 110. The second horizontal direction Y is parallel to the lengthwise direction of the case 110. It will be appreciated that in embodiments not shown, the first horizontal direction X may also be parallel to the length direction of the box. The second horizontal direction Y may also be parallel to the width direction of the cabinet.

The first inclined wall 114 has a discharge opening 115. The container also includes a discharge door 120. The upper end of the discharge door 120 is pivotally connected to the upper end of the first sloped wall 114. In this manner, the discharge door 120 is able to rotate between an open position and a closed position.

With the discharge door 120 in the closed position, as shown in fig. 1 and 5, the discharge door 120 closes the discharge opening 115. The plane of the discharge gate 120 is now substantially flush with the plane of the first sloped wall 114, and the discharge gate 120 does not project outside the first sloped wall 114 (the side of the first sloped wall 114 that is away from the interior space of the bin 110).

With the discharge door 120 in the open position, as shown in FIG. 2, the discharge door 120 opens the discharge opening 115. At this time, the cargo in the box body 110 can be discharged out of the box body 110 through the discharge opening 115 by its own weight.

The discharge opening 115 is provided to the first inclined wall 114, and the discharge opening 115 may be located as close to the center of the case 110 as possible. Thus, the bulk discharged through the discharge opening 115 can be brought close to the center of the box body 110 as much as possible, and the discharged bulk can be concentrated as much as possible. In addition, a discharge door 120 is connected to the first sloped wall 114. Thus, in the process that the discharge door 120 rotates from the closed position to the open position, the lower end of the discharge door 120 moves toward the center of the box body 110, so that the discharge door 120 is prevented from swinging to the outer side of the wall body 111, and the possibility that the discharge door 120 collides with a worker is reduced.

Preferably, the upper end of the first inclined wall 114 and the later second inclined wall 116 are substantially flush in the vertical direction. Thus, it is possible to increase the inner space of the case 110 as much as possible while reducing the clearance as much as possible, and to improve the structure of the case 110 as much as possible, thereby increasing the strength of the case 110 as much as possible.

Referring to fig. 3-5, the container further includes a discharge door drive assembly 130. The discharge gate drive assembly 130 is connected to the discharge gate 120 and the tank 110. In this manner, the discharge door drive assembly 130 is capable of driving the discharge door 120 to rotate between the open and closed positions.

Preferably, the discharge door driving assembly 130 is located at an outer side of the first inclined wall 114 (a side of the first inclined wall 114 away from the inner space of the box body 110). The discharge door driving assembly 130 is located at the outer side of the discharge door 120 (the side of the discharge door 120 away from the inner space of the case 110). This can increase the accommodation space in the case 110. The discharge door driving assembly 130 does not protrude from the outer contour of the case 110. Thus, the transportation of the container is convenient.

As shown in fig. 3 to 5, the discharge door driving assembly 130 includes a movable beam 131, a guide rail 132, a slider 133, and a link 134.

The movable beam 131 is movable in the height direction Z of the cabinet 110. The movable beam 131 is located below the upper end of the first inclined wall 114. The longitudinal direction of the guide rail 132 extends in the height direction Z of the case 110. One end of the guide rail 132 is fixedly connected to a later reinforcing frame 140. The other end of the guide rail 132 is fixedly connected to the first inclined wall 114. The guide rails 132 are located at the sides of the discharge gate 120 in the second horizontal direction Y. The movable beam 131 and the guide rail 132 are located at the outer side of the discharge door 120 in the first horizontal direction X.

The slider 133 is fixedly connected to the movable beam 131. The slider 133 is slidably connected to the guide rail 132 in the vertical direction. Thus, the guide rail 132 and the slider 133 cooperate to guide the movement of the movable beam 131 in the height direction Z of the case 110.

One end of the link 134 is pivotally connected to the lower end of the discharge door 120. The other end of the link 134 is pivotally connected to the movable beam 131, and further, to the slider 133 through the movable beam 131. In this way, when the movable beam 131 moves in the height direction Z of the container body 110, the discharge door 120 is rotated between the open position and the closed position by the link 134, and thus the opening and closing operation of the discharge opening can be performed only by the slider lifting operation of the operation end portion. Thus, the operation of opening or closing the discharge opening 115 is simple.

The longitudinal direction of the movable beam 131 extends in the second horizontal direction Y. The movable beam 131 extends from one end of the discharge gate 120 to the other end in the second horizontal direction Y. At least two links 134 are uniformly arranged along the second horizontal direction Y. Thereby, the discharge door 120 can be driven to move between the open position and the closed position more evenly.

Both sides of the movable beam 131 in the first horizontal direction X are provided with a discharge door 120 and a link 134. Both of the discharge doors 120 located at the side portions of the movable beam 131 in the first horizontal direction X are connected to the movable beam 131 by a link 134. Thereby, the two discharge doors 120 can be moved by one movable beam 131.

The partial discharge door drive assembly 130 is disposed within the central recess of the W-shaped structure (the downwardly opening central recess defined by the two first sloped walls 114). Thereby, the space outside the case 110 occupied by the discharge door driving assembly 130 is reduced as much as possible. In addition, the arrangement of the partial discharge door drive assembly 130 in the middle groove of the W-shaped structure, the stress of the discharge door drive assembly 130 and the structure for bearing the discharge door drive assembly 130 is small, parts with small strength can be adopted, the cost is low, and the operation is simple.

As shown in fig. 4 and 5, the discharge door drive assembly 130 further includes a gear 135, a rack 136, a drive shaft 139 (shown in phantom in fig. 5), a motor 138, and a speed reducer 137.

The rack 136 has a longitudinal direction extending in the height direction Z of the case 110. One end of the rack 136 is fixedly connected to a later reinforcing frame 140. The other end of the rack 136 is fixedly connected to the first inclined wall 114. The rack 136 is located at the side of the discharge gate 120 in the second horizontal direction Y. The rack 136 is located outside the discharge door 120 in the first horizontal direction X. The rack 136 is located at the guide rail 132.

The decelerator 137 is fixedly connected to the movable beam 131. The output shaft of the speed reducer 137 is connected to a drive shaft 139. The motor 138 is fixedly connected to the reducer 137. An output shaft of the motor 138 is connected to an input shaft of the speed reducer 137 to power the speed reducer 137.

The movable beam 131 is a hollow structure. The axis of the drive shaft 139 is substantially parallel to the length direction of the movable beam 131. The transmission shaft 139 is disposed through the movable beam 131. The drive shaft 139 is rotatably connected to the movable beam 131 by a bearing. The axis of the output shaft of the speed reducer 137 is substantially parallel to the second horizontal direction Y. The output shaft of the decelerator 137 is inserted into the movable beam 131 to be connected to one end of the driving shaft 139. The other end of the drive shaft 139 is located outside the movable beam 131 and is connected to the gear 135. The gear 135 is engaged with the rack 136.

Motor 138 may drive rotation of gear 135 via speed reducer 137 and drive shaft 139. The rotating gear 135 is engaged with the rack gear 136 to move the movable beam 131 in the height direction Z of the container body 110, thereby rotating the discharge door 120 between the open position and the closed position by the link 134. There is no need for a manual direct operation of the opening and closing mechanism for opening or closing the discharge door 120 to open the discharge door 120. The operation of opening the discharge door 120 is simple and safe. Nor is there any need to tilt the container in order to discharge the bulk.

As shown in fig. 1-5, the W-shaped structure also has a second sloped wall 116. The second inclined wall 116 is inclined to the first horizontal direction X. The second sloped wall 116 is sloped with respect to the first sloped wall 114. The second inclined wall 116 and the first inclined wall 114 are arranged in this order along the first horizontal direction X. The second inclined wall 116 is located inside the side wall 112 in the first horizontal direction X. Thus, along the first horizontal direction X, neither the first inclined wall 114 nor the second inclined wall 116 protrudes from the outer contour of the side wall 112, which facilitates the transportation of the container.

The upper end of the second inclined wall 116 is connected to the lower end of the side wall 112. The lower end of the second inclined wall 116 is connected to the lower end of the first inclined wall 114. The lower end of the first inclined wall 114 and the lower end of the second inclined wall 116 are located at the lower end of the case 110.

The second inclined wall 116 and the first inclined wall 114 connected thereto form a V-shaped structure with an upward opening. Thereby, the strength of the lower end of the case 110 can be increased. Along the first horizontal direction X, the lower portion of the case 110 is provided with two V-shaped structures. The upper ends of the first inclined walls 114 of the two V-shaped structures are connected to form a W-shaped structure. This can further increase the strength of the lower portion of the case 110. In addition, the bulk cargo discharged through the discharge port 115 may be further brought close to the center of the case 110.

It will be appreciated that in embodiments not shown, the lower end of the first inclined wall may also be directly connected to the lower end of the side wall. The upper ends of the two first inclined walls are connected. Thus, the two first inclined walls and the two side walls form a W-shaped structure.

In this embodiment, the first inclined wall 114 is inclined to the first horizontal direction X, the discharge opening 115 is disposed on the first inclined wall 114, and the upper end of the discharge door 120 is pivotally connected to the first inclined wall 114, so that the discharge door 120 does not occupy too much lower space of the box body when the discharge door 120 is in the open position, and thus, the clearance between the bottom end of the box body 110 and the receiving bin for receiving bulk cargo (the minimum distance between the bottom end of the box body 110 and the receiving bin along the vertical direction) can be as small as possible, and when bulk cargo in the box body 110 is discharged through the discharge opening 115, the height of the free falling body of bulk cargo can be reduced, and thus the dust generated during discharging can be reduced as much as possible; the lower portion of the case 110 is constructed in a W-shaped structure, which can increase the strength of the lower portion of the case 110 and can make the bulk cargo discharged through the discharge port 115 close to the center of the case 110; in addition, the discharge door 120 can be automatically driven to rotate between the opening position and the closing position by the discharge door driving assembly 130, manual operation is not needed, and the operation of rotating the discharge door 120 is simple and safe.

Further preferably, the first inclined wall 114 is located on the inner side of the second inclined wall 116 in the first horizontal direction X (a side of the second inclined wall 116 in the first horizontal direction X close to the center of the case 110). Thereby, the bulk cargo discharged through the discharge opening 115 can be brought closer to the center of the case 110.

Preferably, the discharge opening 115 extends to the lower end of the first inclined wall 114 in the height direction Z of the case 110. Thus, the lower end of the second inclined wall 116 and a portion of the first inclined wall 114 constitute the discharge opening 115. Therefore, the first inclined wall 114 and the second inclined wall 116 can be prevented from forming an angle structure with an upward opening, and bulk cargo can be prevented from being accumulated.

With the discharge door 120 in the open position, the discharge door 120 may not protrude or may protrude at least partially beyond the outer contour of the bin 110, minimizing the amount of space outside the bin 110 that is occupied by the discharge door 120 in the open position.

Preferably, as shown in FIG. 5, the discharge door 120 is provided with a discharge door reinforcement beam 156. The discharge door reinforcement beam 156 extends from the upper end to the lower end of the discharge door 120. Thereby, the strength of the discharge door 120 can be increased.

Preferably, as shown in fig. 5, the second inclined wall 116 is provided with an inclined wall reinforcement beam 157. The length direction of the slant wall reinforcement beam 157 extends in the height direction Z of the box body and is inclined to the first horizontal direction X. The inclined wall reinforcing beam 157 extends from one end of the second inclined wall 116 to the other end in the height direction Z of the tank. Thereby, the strength of the second inclined wall 116 can be increased.

Preferably, the tank also has a baffle 158. The baffle 158 is connected to the first sloped wall 114. A baffle 158 is located at the upper end of the discharge opening 115. The barrier 158 covers the door slot at the upper end of the discharge door 120. The baffles 158 are located on the inside of the discharge door 120 (the side of the discharge door 120 adjacent the bin 110). In this way, the shield plate 158 may shield the door seam at the upper end of the discharge door 120. Thus, in the process of the discharge door 120 being in the open position to discharge the bulk cargo, the barrier 158 may block the door opening at the upper end of the discharge door 120, preventing the bulk cargo from remaining in the door opening at the upper end of the discharge door 120, and thus preventing the bulk cargo from obstructing the discharge door 120 from moving to the closed position.

Referring to fig. 5, the case 110 further includes a reinforcing frame 140. The reinforcing frame 140 is located at the first inclined wall 114 in the height direction Z of the cabinet 110, and is connected to the first inclined wall 114. This can increase the strength of the lower portion of the case 110.

Preferably, the reinforcing frame 140, the wall 111, and the ceiling wall are configured in a substantially rectangular parallelepiped structure. Thus, the transportation of the container is convenient.

Specifically, four corners of the case 110 are each provided with a corner post 153. The end of the corner post 153 is provided with a corner fitting. Thereby, the box can be fixed or transported by the corner fitting.

The wall 111 is provided with a wall pillar. The longitudinal direction of the wall column extends in the height direction Z of the case 110. Specifically, an end wall pillar 155 is disposed at the end wall 113. A sidewall pillar 154 is disposed at the sidewall 112. The upper ends of the end wall columns 155 are connected to the top end beams 118. The upper ends of the side wall pillars 154 are connected to the roof side rail 117. This can increase the strength of the wall 111.

The reinforcing frame 140 further comprises a bottom end beam 141 and a bottom side beam 142. Bottom end beam 141 is located directly below top end beam 118. The bottom side members 142 are located directly below the top side members 117. The longitudinal direction of the bottom side members 142 extends in the second horizontal direction Y. The length direction of the bottom end beam 141 extends along the first horizontal direction X. The bottom end beam 141 is located at an end of the case 110 in the second horizontal direction Y. The bottom side members 142 are located at the sides of the case 110 in the first horizontal direction X. The bottom end beam 141 and the bottom side beam 142 constitute a substantially rectangular frame. The rectangular frame is located at the lower end of the case 110. The corners of the rectangular frame are connected to corner posts 153. This can further increase the strength of the lower portion of the case 110.

The reinforcing frame 140 further includes a bottom cross member 143 at a lower end of the case 110. The length direction of the bottom cross beam 143 is substantially parallel to the length direction of the bottom end beam 141.
