Description

Technical Field

[0001] The utility model relates to the technical field of port bulk cargo ship loading, in particular to a bulk cargo container. Background Art

[0002] In the traditional port bulk cargo ship loading process flow, the cargo is transported and loaded and unloaded by an iron dustpan hopper. In actual production operations, the use of the iron dustpan hopper has relatively limitations. Its loading volume is small, the loading and unloading efficiency is low, and the sealing performance is poor. During the loading and unloading and transportation process, it is easy to spill the cargo, causing dust pollution to the environment, and there are potential safety risks for the cargo and personnel during loading and unloading. It can no longer meet the actual bulk cargo ship loading operations of the port with increasing high efficiency, low energy consumption, pollution suppression, and strong safety. Based on the above considerations, through innovation, a bulk cargo loading and unloading container tool is developed, which has a large loading volume, high loading and unloading efficiency, is durable, has a tight seal, is easy to operate, is practical and universal, energy-saving and environmental-friendly, and is scientifically safe for use in port bulk cargo ship loading operations.

[0003] The existing iron dustpan hopper will generate a large area of dust during unloading; the loading volume of the existing iron dustpan hopper is relatively small, which cannot meet the needs of loading and transporting large-capacity goods, the loading and transporting efficiency is low, and the existing iron dustpan hopper is prone to cargo overflow during loading, resulting in high manual cleaning and mechanical use costs. It is easy to spill the cargo during transportation due to bumps, and there are risks of cargo damage and safety; the lifting points of the existing technology are set at the four top edges of the iron dustpan hopper, which is not conducive to the crane to lift the hopper unilaterally.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following further describes the present utility model in detail with reference to specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] Embodiment 1

[0032] A bulk container, see Figures 1-5 , including a main body support 1 and multiple box body plates 2.

[0033] The main body support 1 includes multiple cross beams 1-1 and multiple longitudinal beams 1-2. The multiple cross beams 1-1 and the multiple longitudinal beams 1-2 are welded and assembled into a cuboid main body support. A box body plate 2 is welded to each side of the main body support 1 except the top surface to form a box body. The cross beam 1-1 includes a long cross beam and a short cross beam. A long reinforcing cross rib 1-3 is welded inside each long cross beam, and a short reinforcing cross rib 1-4 is welded inside each short cross beam. A reinforcing vertical rib 1-5 is welded inside each longitudinal beam 1-2 to strengthen the support for the main body support 1. Multiple pairs of reinforcing vertical ribs 1-5 are welded between the upper and lower two long reinforcing cross ribs 1-3 on both sides. A tension rib 1-6 is welded at the middle position of each pair of reinforcing vertical ribs 1-5 to further strengthen the support for the main body support 1, so as to realize the support for the box body and balance the weight of the goods in the box body. Among them, the preferred number of welded reinforcing vertical ribs 1-5 between the upper and lower two long reinforcing cross ribs 1-3 in this embodiment is 2 pairs. The top of the box body is fully open, which can improve the loading efficiency.

[0034] The box body plate 2 in this embodiment is a heightened box body plate, and the height of the box body plate 2 is 2500mm - 2600mm. Therefore, the inner wall of the box body is higher than that of the traditional iron dustpan hopper, and it is not easy to cause material overflow during loading, effectively reducing the manual cleaning and mechanical use costs of the overflowed materials. Moreover, the loading volume of the box body is large, and it can load more goods, which can reduce the number of transports, improve the transport efficiency, and thus save costs such as labor, vehicles, and fuel.

[0035] An unloading port is opened at the bottom end of the front box body plate 2, and an automatic unloading door 3 is installed at the top of the unloading port. The automatic unloading door 3 includes a door panel 3-1, a short pin shaft 3-2, a long pin shaft 3-3, and a counterweight 3-4. The top of the door panel 3-1 is hinged to the unloading port through a connecting piece 3-1-1. When the door panel 3-1 is opened, the unloading port is in an open state for unloading. When the door panel 3-1 is closed, the unloading port is in a closed state, and the goods are loaded in the box body.

[0036] A short pin shaft jack 3-1-2 is provided on the door panel 3-1, and a first jack 3-4-1 is provided at the upper end of the counterweight 3-4. When the short pin shaft 3-2 is sequentially inserted into the short pin shaft jack 3-1-2 and the first jack 3-4-1, the counterweight 3-4 is fixed on the door panel 3-1. The short pin shaft 3-2 fixes the counterweight 3-4 to prevent the counterweight 3-4 from falling abnormally during transportation, causing the door panel 3-1 to open abnormally and the goods to spill.

[0037] A plurality of long pin shafts insertion holes 3-1-3 are further provided on the door panel 3-1. A second insertion hole 3-3-1 is formed on the front side of the main body bracket 1. When the long pin shaft 3-3 is inserted into the long pin shaft insertion holes 3-1-3 and the second insertion hole 3-3-1, the door panel 3-1 is fixed on the main body bracket 1, which is used to enhance the tightness of the automatic discharge door 3 during gravity-free horizontal transportation, so as to avoid the abnormal opening of the door panel 3-1 caused by the dropping of the counterweight 3-4 during transportation due to factors such as jolting, and prevent the leakage of the cargo material.

[0038] The counterweight 3-4 includes a counterweight plate and two connecting arms. The two connecting arms are symmetrically arranged on the counterweight plate. A through hole is provided at the bottom of each connecting arm. The connecting arm is rotationally connected to the middle part of the long pin shaft 3-3 through the through hole; the upper end of the counterweight plate is inclined outward relative to the door panel. When the box body is hoisted at a preset angle, the through hole of the connecting arm rotates around the long pin shaft 3-3, so that the counterweight 3-4 drops, thereby driving the door panel 3-1 to open, and the discharge port is in an open state for discharging; the top of the counterweight 3-4 is connected to the door panel 3-1 through a safety chain 3-4-2, which is used to limit the dropping angle of the counterweight 3-4 and prevent the dropping angle of the counterweight 3-4 from being too large and affecting the opening of the door panel 3-1. Affected by the self-weight of the counterweight 3-4, the door panel 3-1 will not close after being opened by gravity, ensuring smooth discharge of the cargo material and efficient shipment. Among them, sealing strips are provided on both sides and the bottom of the door panel 3-1 to prevent the leakage of the cargo material in the box body.

[0039] Furthermore, an iron plate is additionally installed at the bottom layer of the box body to enhance the overall strength of the box body.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, lifting points 1-7 are provided around the bottom of the main body bracket 1 for connecting with a crane and lifting the box body unilaterally by the crane for unloading. The lifting points 1-7 are in an arc shape.

[0042] Embodiment 3

[0043] On the basis of Embodiments 1-2, a plurality of shovel tooth holes 1-1-1 adapted to the forklift shovel teeth are formed on the cross beams 1-1 on both sides of the bottom of the main body bracket 1, which are used to horizontally move the box body by a forklift.

[0044] Embodiment 4

[0045] On the basis of Embodiments 1-3, a working method for a bulk cargo container includes the following steps:

[0046] Step 1: Insert the short pin shaft 3-2 into the short pin shaft jack 3-1-2 and the first jack 3-4-1 in sequence to fix the counterweight 3-4 on the door panel 3-1. Then insert the long pin shaft 3-3 into the long pin shaft jack 3-1-3 and the second jack 3-3-1 to fix the door panel 3-1 on the main body bracket 1;

[0047] Step 2: Load the bulk goods from the top opening of the box body. Insert the forklift teeth into the forklift tooth hole 1-1-1, and move the box body to the designated position by the forklift;

[0048] Step 3: Open the short pin shaft 3-2 and the long pin shaft 3-3, connect the crane with the lifting point 1-7, lift the box body by the crane. When the box body tilts downward to a preset angle, the counterweight 3-4 drops, thereby driving the door panel 3-1 to open for discharging.

[0049] When the counterweight 3-4 drops, use the safety chain 3-4-2 to limit the dropping angle of the counterweight 3-4 to prevent the dropping angle of the counterweight 3-4 from being too large and affecting the damage to the door panel 3-1.

[0050] For ease of explanation, in the embodiments, spatial relative terms such as "upper", "lower", "left", "right", etc. are used to describe the relationship between one element or feature shown in the figure and another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0051] Moreover, relative relationship terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0052] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
