Loading and unloading device and loading and unloading method for loading and unloading standard containers for large steel structural parts

Abstract

The invention discloses a loading and unloading device and loading and unloading method for loading and unloading standard containers for large steel structural parts. The loading and unloading device comprises a bearing support, a hydraulic lifting loading and unloading trolley, a packaging bracket, a hydraulic station, a control cabinet and an operation table. The bearing support is used for providing support for the hydraulic lifting loading and unloading trolley when the hydraulic lifting loading and unloading trolley loads and unloads the standard containers for the steel structural parts. The hydraulic lifting loading and unloading trolley is used for entering a standard container to load or unload the packaged steel structural parts. According to the fast, efficient, stable and reliable loading and unloading device and loading and unloading method for loading and unloading the standard containers for the large steel structural parts, the problem that existing equipment and technologies are inconvenient for loading and unloading the standard containers for the large steel structural parts is solved, and the working efficiency, safety and stability of loading and unloading the standard containers for the large steel structural parts are improved; the comprehensive cost, the labor intensity and the encasement risk are reduced, and the working environment of operators is improved.

Description

technical field [0001] The invention relates to the technical field of steel structure transportation, in particular to a loading and unloading device and method for loading and unloading standard containers of large steel structures. Background technique [0002] Usually, the transportation of steel structure components in overseas engineering projects basically chooses container transportation, mainly because most of the steel structure components are in irregular shapes. Due to damage to components caused by unknown factors such as wind and waves, it can better protect the steel structure components safely and stably. [0003] There are many types of containers. Since the steel structure components are steel products, and most of them are heavy cargo, it is most suitable to use open-top containers, which can be loaded and unloaded directly from the top by cranes. Usually, the steel structures in overseas engineering projects are tens of thousands Tons, or even hundreds o...

Problems solved by technology

Considering that steel components can be packed as much as possible, they are usually packaged according to different sizes of standard containers (the steel components are larger in size and heavier in weight). The packaged steel components are similar to the internal dimensions of standard containers, leaving a slight safety gap. Unable to complete the task of entering the interior of a standard container for loading and unloading

[0005] At present, when steel structure processing units pack steel structure components (standard containers), they usually adopt the traditional method of step-by-step lifting by crane + external push. Place a temporary horse stool at a distance (depending on the length of the component) (sometimes the estimate is not accurate, and the horse stool has to be moved back and forth), apply butter on the bottom of the container and lay wooden boards (to facilitate the later push of the steel component. The friction force is small, However, some transport units do not agree to adopt this method due to oil pollution), and then use a crane to lift 1 / 3 of the steel components into the container. To continue packing, the steel components can only be dropped (at this time, part of the steel components are in the container, and some are on the pre-placed horse stool), and the lifting point is replaced to lift the remaining steel components on the horse stool. The push method continues to push the steel member into the container

With this traditional packing method, when replacing the lifting points, it is difficult for construction workers to remove the spreader or hook, especially the pair of lifting points that enter the interior of the container, and there is a safety risk of crushing injuries; when pushing outside, It is difficult to ensure the balance of the left and right sides of the force point, which can easily cause damage to steel components or standard containers; this method is not only labor-intensive and time-consuming, but also prone to mechanical or personal accidents, and the cost and safety risks of packing are high, which is not conducive to enterprise development and competition
