Description

Technical Field

[0001] This invention relates to a container overload detection and adjustment device, belonging to the field of container technology. Background Technology

[0002] A shipping container is a large cargo container with a certain strength, rigidity, and specifications, specifically designed for repeated use. Using containers for cargo transshipment allows for direct loading at the shipper's warehouse and unloading at the consignee's warehouse. When changing vehicles or ships en route, there is no need to remove the goods from the container for repacking, making it extremely convenient and efficient. Therefore, the shipping container is a great invention. As a standard transport unit, the shipping container has evolved into various types of specialized transport containers based on the goods it transports and the limitations of the conditions, including dry cargo containers, open-top containers, platform and rack containers, ventilated containers, refrigerated containers, bulk cargo containers, tank containers, and other special-purpose containers.

[0003] Various powdered materials and dry goods are also stored and transported using containers. During the loading of these materials into containers, uneven material distribution occurs, with some areas piled high and others low. This uneven distribution poses significant safety hazards during lifting, moving, and transportation. Existing technologies include various container off-center loading detection devices. Containers containing powdered materials or dry goods are placed on a platform equipped with multiple vibrating elements. The vibration of these elements supposedly homogenizes the materials inside the container. However, this homogenization method is sometimes ineffective and inefficient. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of limited overload adjustment effect and low efficiency in the prior art, and to provide a container overload detection and adjustment device.

[0005] This invention is achieved through the following technical solution: The present invention relates to a container overload detection and adjustment device, comprising a detection and adjustment platform, which has two width-direction receiving slots and two length-direction receiving slots. A width-direction ramp is provided at the outer edge of the width-direction receiving slot, and a length-direction ramp is provided at the outer edge of the length-direction receiving slot. A width-direction adjustment mechanism is provided in the width-direction receiving slot, and a length-direction adjustment mechanism is provided in the length-direction receiving slot. A weighing unit is provided at each of the four corners of the upper end of the detection and adjustment platform. Four vibration units are also provided at the upper end of the detection and adjustment platform, and the vibration units are located inside the weighing units. The width adjustment mechanism includes a hydraulic cylinder 1 installed on the width receiving groove, with two rollers 1 mounted on the end of the hydraulic rod of the hydraulic cylinder 1. The length adjustment mechanism includes a hydraulic cylinder 2 installed on the length receiving groove, with two rollers 2 mounted on the end of the hydraulic rod of the hydraulic cylinder 2.

[0006] Containers containing powdered materials and dry goods are placed on the inspection and adjustment platform. Weighing units at the four corners detect overload and off-center loading of the containers. Based on the inspection results, it is determined whether the containers are overloaded and in which locations. Based on the specific locations of overload, hydraulic cylinders one and two drive rollers one and two to move along the ramps in the width and length directions to lift the containers. Then, the vibration unit is activated to vibrate and homogenize the containers. This method provides better and more efficient adjustment for overload and off-center loading of the containers.

[0007] Further preferred, the top of the vibration unit is flush with the top of the detection and adjustment platform, and the vibration unit includes a vibration element.

[0008] Further optimization involves a box-shaped structure with a movable upper plate. The vibration element is a vibration motor located inside the box structure and connected to the movable upper plate. A lifting cylinder is located at the bottom of the box structure, with its piston rod connected to the vibration motor. The lifting cylinder raises the vibration motor, causing the movable plate to contact the bottom of the container, resulting in good vibration homogenization and high efficiency.

[0009] Further optimization includes the weighing unit incorporating a pressure sensor.

[0010] Further preferred, a hinge seat 1 is fixedly provided in the accommodating groove in the width direction, the cylinder body of hydraulic cylinder 1 is hingedly connected to hinge seat 1, a U-shaped frame 1 is installed on roller 1, the two U-shaped frames 1 are connected by a connecting plate 1, a hinge seat 2 is fixedly provided on the connecting plate 1, and the hinge seat 2 is hingedly connected to the hydraulic rod of hydraulic cylinder 1. A hinge seat three is fixedly installed within the longitudinal accommodating groove. The cylinder body of hydraulic cylinder two is hingedly connected to hinge seat three. A U-shaped frame two is mounted on roller two, and the two U-shaped frames two are connected by a connecting plate two. A hinge seat four is fixedly installed on the connecting plate two, and hinge seat four is hingedly connected to the hydraulic rod of hydraulic cylinder two. Hydraulic cylinder one and hydraulic cylinder two drive roller one and roller two to move through the above structure, which is simple and reliable.

[0011] Further optimization involves ensuring that, when hydraulic cylinders one and two are in their longest extended state, the vertical center planes of rollers one and two are flush with the outer facade of the container. This facilitates the lifting operation of the container; the retraction of the hydraulic cylinders from their longest extended state constitutes the lifting operation.

[0012] Further optimization involves the tops of roller one and roller two contacting the bottom surface of the container, and the bottoms of roller one and roller two contacting the ramps in the width direction and the ramps in the length direction.

[0013] Further optimization involves a design where the distance between the two rollers (secondary) in the length adjustment mechanism is greater than the distance between the two rollers (primary) in the width adjustment mechanism. Since the container's length is greater than its width, this design improves the stability of the container lifting process.

[0014] Compared with the prior art, the beneficial effects of this invention are: Containers containing powdered materials and dry goods are placed on the inspection and adjustment platform. Weighing units at the four corners detect overload and off-center loading of the containers. Based on the inspection results, it is determined whether the containers are overloaded and in which locations. Based on the specific locations of overload, hydraulic cylinders one and two drive rollers one and two to move along the ramps in the width and length directions to lift the containers. Then, the vibration unit is activated to vibrate and homogenize the containers. This method provides better and more efficient adjustment for overload and off-center loading of the containers.
