Description

Hydraulic lifting loading and unloading trolley for loading and unloading standard container of large steel structural part

Technical Field

The utility model relates to the technical field of logistics transportation of large steel structures, in particular to a hydraulic lifting loading and unloading trolley for loading and unloading standard containers of large steel structures.

Background

When loading and unloading the cargoes, small and light cargoes are mostly loaded and unloaded by adopting equipment or machines such as a forklift and the like, and the cargoes enter the inside of the standard container after the door is opened from one side of the standard container. Considering that the steel members can be packaged as many as possible, the steel members are generally packaged according to different sizes of the standard container (the steel members are large in size and heavy in weight), the packaged steel members are similar to the standard container in internal size, a safety gap is left slightly, and the forklift cannot complete entering the standard container to carry out loading and unloading tasks.

At present, when a steel structure processing unit is used for boxing steel structure components (standard containers), a traditional mode of step-by-step lifting and external pushing of a crane is generally adopted, a standard container transport vehicle is driven to a loading position, temporary split heads (sometimes, when estimation is not performed, the split heads are also required to be moved back and forth) are placed at a certain distance (depending on the length of the components) behind a box door, butter is smeared at the bottom of the container, a wood board is paved (friction force which is convenient for later pushing the steel components is small, but some transportation units do not agree with the adoption of the method due to greasy dirt), then 1/3 of the steel components are firstly lifted into the container by the crane, at the moment, slings of the crane basically touch the top of the container, the steel components cannot be continuously boxed any more, only the steel components can be dropped down (at the moment, one part of the steel components is in the container, and the other part of the steel components are on the split heads placed in advance), lifting points are replaced, the rest of the split heads are lifted, and the steel components on the split heads are continuously pushed into the container by the mode of matching with external pushing.

In the traditional boxing method, when the hanging points are replaced, the lifting devices or hooks of constructors are difficult to remove, particularly the pair of hanging points entering the container, and the safety risk of extrusion injury exists; when the outside is pushed, the stress points are difficult to ensure the balance of the left side and the right side, and the damage of the steel member or the standard container is easily caused; the method is labor-and time-consuming, easy to cause mechanical or personal accidents, high in boxing cost risk and safety risk, and unfavorable for enterprise development and competition.
