Description

Technical Field

[0001] The invention relates to a container dry bulk cargo weighing device and a weighing method, belonging to the technical field of containers. Background Art

[0002] A container is a large cargo container with certain strength, rigidity and specifications for turnover. When using containers to transport goods, the goods can be loaded directly at the shipper's warehouse and unloaded at the consignee's warehouse. When changing vehicles or ships in the middle of the journey, there is no need to take the goods out of the container for reloading. It is very convenient and efficient to use. Therefore, the container is a great invention. As a standard transportation unit, containers have been extended into various types of special transportation containers according to the goods they transport and the restrictions of the conditions, including dry cargo containers, open-top containers, platform and platform containers, ventilated containers, refrigerated containers, bulk containers, tank containers, and special containers.

[0003] Dry cargo containers are used to load dry bulk cargo, which is often unevenly distributed in the container, with some locations being heavier and some locations being lighter. Unevenly weighted containers pose certain safety risks when being lifted, transferred, or transported using transportation vehicles, and may damage lifting equipment and transportation vehicles.

[0004] In order to prevent uneven weight of dry bulk cargo in the container, special attention should be paid when loading dry bulk cargo, and try to load the dry bulk cargo evenly in the container; once uneven weight of dry bulk cargo in the container occurs, equipment and tools can be used to enter the container to perform an even weight operation on the dry bulk cargo. The above two weighing methods are time-consuming and labor-intensive, and have low efficiency. Summary of the invention

[0005] The purpose of the present invention is to solve the technical problem that the weighing operation of dry bulk cargo in a container is time-consuming and labor-intensive in the prior art, and to provide a container dry bulk cargo weighing device and weighing method.

[0006] The present invention is achieved through the following technical solutions: That is, a container dry bulk cargo weighing device, comprising a bottom plate, four corners of the bottom plate are respectively fixed with a hydraulic platform, the hydraulic platform is a box structure, at least one hydraulic oil cylinder is fixedly arranged in the hydraulic platform, the piston rod of the hydraulic oil cylinder is fixedly connected to the top plate of the hydraulic platform, a weighing meter is arranged in the hydraulic platform, and has an independent weighing function, a small vibration platform is arranged on the inner side of each hydraulic platform, a large vibration platform is arranged between the two hydraulic platforms on the same side, and two pairs of support platforms are arranged between the two large vibration platforms; The heights of the small vibration table, the large vibration table and the supporting table are equal, the lowest height of the liftable hydraulic table is lower than the height of the small vibration table, and the highest height of the liftable hydraulic table is higher than the height of the small vibration table.

[0007] The container is transferred to the weighing device of the present invention. The hydraulic table can drive the container to rise and fall. The small vibration table and the large vibration table play a vibrating role, and the dry bulk cargo in the container can be weighed evenly. A weighing scale is provided in the hydraulic table. The degree of weighing evenness of the dry bulk cargo in the container can be known according to the numerical display of the four weighing scales. Whether the weighing is qualified or not is displayed by the indicator light. If it is unqualified, the hydraulic table drives the container to descend, and the container falls on the small vibration table and the large vibration table for vibration. After the vibration, the hydraulic table drives the container to rise, and weighs again until the indicator light shows that the weighing is qualified. Using the weighing device of the present invention to weigh the container is time-saving, labor-saving and efficient.

[0008] More preferably, the bottom plate is in a rectangular shape.

[0009] Further preferably, the small vibration table and the large vibration table are box structures, and vibration elements are arranged inside the small vibration table and the large vibration table.

The vibration required in the length direction of the container is more intense, and the vibration required in the width direction of the container is not as intense as in the length direction. The arrangement of the vibration elements as described above is very reasonable, and the weight balancing efficiency is higher.

[0011] The present invention also provides a method for weighing dry bulk cargo in a container, comprising the following steps: S1: Use lifting equipment to lift the container loaded with dry bulk cargo onto the weighing device; S2: The hydraulic platform weighs the container. If the weight of the container is evenly distributed, the indicator light turns green and the container is lifted and transferred using the lifting equipment; S3: If the weight of the container is unevenly distributed, the indicator light turns red, and the hydraulic platform descends until the container is placed on the small vibration platform and the large vibration platform. The small vibration platform and the large vibration platform start the small vibration platform and the large vibration platform around the heaviest part according to the weight measured by the hydraulic platform at different parts and the weight display of the weighing scale in the hydraulic platform; S4: After the vibration weighing, the hydraulic platform rises again for weighing. After the weighing passes, the indicator light turns green, and the container weighing is completed; S5: Use lifting equipment to lift and transfer the container.

[0012] Further preferably, the weighing scales in the four hydraulic platforms respectively display a weight value, and when the difference between the four weighing scales is greater than a preset value, the indicator light turns red, and when the difference between the four weighing scales is less than or equal to the preset value, the indicator light turns green.
