Description

This application claims the priority of China Patent Application No. 201610389287.0, entitled WIDE BODY CONTAINER FOR CARGO TRANSPORTATION, registered in

The State Administration for the Protection of Intellectual Property of China on June 3, 2016, which is incorporated into this document by reference in its entirety.

FIELD OF THE INVENTION

The invention relates to the field of container technology, in particular to a container for transporting dry bulk cargo such as grain. This application also relates to a vehicle equipped with a container.

State of the art

Container transport is a direction for the development of logistics systems in the world. In addition, in the field of transporting grain and other dry bulk goods, the method of loading and transporting bulk products in bulk is very common, and the transportation method combining container transport in bulk, i.e. container transport for bulk materials has become economical in terms of energy costs, with low cost, with low losses, a cost-effective way of transportation.

Most conventional bulk containers are standard 20-foot (6.1 m) bulk containers (as in FIG. 1), the dimensions of which correspond to the standard external dimensions according to ISO 668. Series 1 freight containers. Classification, dimensions and ratings that is, the maximum outer dimensions of the container are limited in the range 6058 mm X 2438 mm X 2591 mm (length X width X height), limited by the outer sides of the upper corners 2 'and the lower corners 8', and the volume of nent 31.9 m ^3. This type of container is loaded from above and unloaded from below. When unloading cargo, a tipper vehicle or special-purpose unloading equipment is used to lift one end of the container and tilt the container with respect to the door with the possibility of unloading the cargo by gravity or manually.

A conventional container for dry bulk cargo can satisfy the requirements for loading and unloading in bulk dry bulk cargo and can also satisfy the requirements of container transportation, however a conventional container has some disadvantages in use.

Firstly, a conventional container has a small capacity, low carrying capacity, which leads to a loss in transporting capacity. The external dimensions of the TEU (Twenty-Foot Equivalent Unit - the twenty-foot equivalent used to characterize the capacity of a standard 20-foot container) are subject to stringent requirements, with the result that the standard width is 2438 mm. However, the maximum width of the outer dimensions of vehicles on the roads in China is 2550 mm, and the maximum width of railway rolling stock can reach 3200 mm. TEU, due to width limitations, has a low utilization ratio with respect to the limit. Therefore, TEUs with the same length and height have a small volume and low carrying capacity compared with the same type of railway and road vehicles. In addition, due to the small volume, when loading and transporting grain or other bulk cargo, the vehicle cannot be fully loaded, which leads to a loss of transport capacity.

Secondly, unloading requires a special vehicle or special-purpose unloading equipment, or is performed manually, which cannot be emptied by itself. Therefore, unloading has low efficiency and high cost.

Therefore, the technical problem that must be solved by a specialist in this field of technology is to increase the capacity of loading and unloading containers for transporting bulk cargo.

SUMMARY OF THE INVENTION

An aspect of this application is the creation of a wide-body container for transporting bulk cargo. The side walls of the container are wide-body structures such that the space within the standard was effectively used, and the volume could be increased by 5% -20%. Thus, the loading capacity of the transport container is increased, and the transporting capacity of the vehicle is fully utilized, thereby the overall efficiency is high. In addition, the transport container includes a lower frame and unloading means of the lower side doors, which can automatically unload the cargo without the need for any equipment and without residue, which not only increases efficiency, but also reduces cost.

Another aspect of this application is the creation of a vehicle equipped with a container.

Detailed Description of Embodiments

An aspect of the present invention is to increase the volume with the possibility of increasing the loading capacity of the transport container due to the expanding side walls of the container, and the use of an inclined lower frame and lower means of unloading the side walls for automatic unloading of the cargo, increasing efficiency, and reducing cost.

To enable a person skilled in the art to better understand the solutions of the present application, the present application is further described in more detail below with reference to the drawings and embodiments.

Referring to FIG. 2, 3, 4 and 5, FIG. 2 is a schematic view showing a structure according to an embodiment of a wide-body container for transporting bulk cargo in accordance with the present application; FIG. 3 is a schematic view showing the structure of the lower frame in FIG. 2; FIG. 4 is a schematic view showing the construction of a right side wall in FIG. 2; and FIG. 5 is a view according to FIG. 4 when viewed from direction A.

In a specific embodiment, the wide body container for transporting bulk cargo according to the present application is a closed container mainly comprising a front end wall 1, a rear end wall 2, a left side wall 3, a right side wall 4, a roof 5 and a lower frame 6 that is waterproof leak proof. The roof 5 of the container is provided with a cover 7 loading holes, which provides the loading of dry bulk cargo such as grain, on top of the container, and is equipped with devices such as many upper corner elements 8 and many lower corner elements 9. Many upper corner elements 8 and many lower corner elements 9 are placed in positions that define the TEU, and eight corner elements enclose a space of 6058 mm X 2438 mm X 2591 mm (length X width X height). Therefore, the container is suitable not only for conventional vehicles, but also for conventional container distribution devices.

The left side wall 3 and the right side wall 4 form a wide-body structure with a width exceeding the outer sides of the upper corner elements 8 and the lower corner elements 9, and the width between the left side wall 3 and the right side wall 4 is greater than the width of 2438 mm TEU, but less than the maximum width in accordance with regulatory road restrictions. If the container is intended for a road vehicle, the width of the container should be less than the maximum width of 2550 mm in external dimensions, and if the container is intended for railway rolling stock, the width of the container should be less than the maximum width of 3200 mm.

Specifically, the left side wall 3 and the right side wall 4 are symmetrical from left to right. Using the right side wall 4 as an example, it includes an upper inclined section 4-1 attached to the roof 5, a lower inclined section 4-2 connected to the lower frame 6, a vertical side section 4-3, the front sealing section 4- 4,

- 3 034192 attached to the front end wall 1, and the rear sealing portion 4-5, attached to the rear end wall 2.

Of course, the left side wall 3 and the right side wall 4 can be expanded by a variety of structures. The upper part of the expanded section may not be inclined, but be on the same level with the roof 5, and only the lower part of the expanded section is made with the possibility of placement at an angle. Alternatively, the lower part of the expanded section may not be inclined, but be on the same level with the lower frame b, and only the upper part of the expanded section is arranged to be placed at an angle; alternatively, the upper part and the lower part of the enlarged section are placed at the same level with the roof 5 and the lower frame 6, respectively; alternatively, the upper part and the lower part of the expanded portion are in the form of an arch, and the like.

The bottom of the lower frame 6 has an inverted V'-shaped section, which is inclined downward in two directions from the middle, respectively. The left side wall 3 and the right side wall 4, respectively, are provided with a lower side door for unloading cargo at their lower inclined sections. During the unloading process, the bottom plays the role of directing the cargo flow, and under the influence of its own gravity, the load will naturally pass into the lower side doors 10 on two sides.

It should be understood that the greater the angle of the ridge of the bottom of the lower frame 6, the lower the height of the bottom, and the volume of the container occupied by the bottom due to the ridge of the bottom will be less in accordance with the formula for calculating the volume, which helps to increase the capacity of the container and increase the transport cargo capacity, in another aspect, due to the small height of the bottom, the bevel angle on each of the two sides will be small, and the material flow rate during unloading will be relatively low, which, to a certain extent, will affect the efficiency of manual ultrasonic inspection. On the other hand, the smaller the angle of the ridge of the bottom of the lower frame 6, the greater the height of the bottom, and the volume of the container occupied by the bottom due to the ridge of the bottom is larger, which does not increase the capacity of the container and increase the transport cargo capacity, in another aspect, due to greater height of the bottom, the bevel angle on each of the two sides will be steeper, and the material flow rate during unloading will be relatively high, which ensures an increase in unloading efficiency.

To balance the capacity of the container and the efficiency of unloading, it is advisable to make the ridge angle, for example, 130 degrees-165 degrees, in particular, in the case when the ridge angle is 120 degrees, it is impossible to provide only a higher container capacity, but also provide higher efficiency unloading, thereby satisfying the requirements of practical use.

The number of lower side doors 10 on each side is two, and the two lower side doors 10 are placed side by side in the longitudinal direction of the container, and each are pivotally connected to the lower inclined portion at the upper edge of the corresponding door opening, and each additionally equipped with a locking mechanism, which must be closed or opened from the lower edge of the corresponding door opening. Thus, when the lower door 10 is not fixed, it will naturally be in a lowered vertical state under the action of gravity so that the door can be opened without the help of external force, and can be further deployed outward by the buoyancy force from the material flow side, and the door opening is enlarged so that the material exits the container with a higher velocity and volumetric flow rate, and unloading is carried out for the shortest possible time interval.

It should be understood that depending on the length of the container or the specific structures of the lower side doors, the number of lower side doors 10 may also be one or three, four or even more, which can be determined in accordance with practical requirements.

Reference is made to FIG. 6, which is a schematic view showing a wide-body container for transporting bulk cargo in FIG. 2, unloading on a vehicle without being removed from the vehicle.

As shown in the drawing, this wide-body container for transporting bulk cargo takes the same position of the corner elements as the corner elements of a standard container, and can be used with conventional container vehicles and conventional container dispensers. Each of the side walls is made in the form of an ultra-wide design, but does not exceed the requirements for the width established by regulatory road restrictions, and their width can be adjusted in accordance with regulatory road restrictions, to maximize the container volume in the range allowed in accordance with regulatory restrictions. In addition, this wide-body container for transporting bulk cargo accepts a lower frame structure with an inclined bottom and a structure with lower side doors, which can be unloaded without removing from the vehicle, and by simply opening the door, the cargo can be immediately unloaded automatically without a trace, and not special unloading equipment is required, which significantly increases the efficiency of unloading and reduces operating costs.

The above embodiments are only preferred solutions of the present application, and the present application is not limited thereto. Based on this, special refinements may be made in accordance with practical requirements to obtain other embodiments. For example, the upper corner elements 8 and the lower corner elements 9 are placed in positions identical with other types of standard angles, or the lower side door 10 is opened by turning down, etc. Since there are many ways in which we can do this, these methods will not be illustrated here individually.

In addition to the above-described wide-body container for transporting bulk cargoes, a vehicle is further provided according to the present application, which may be a railway vehicle or a freight vehicle, including: a base with a warhead; and a container placed on the base.
