Combined loading and unloading device, and loading and unloading method for overweight or overlong objects in container

Abstract

The invention discloses a combined loading and unloading device, and a loading and unloading method for overweight or overlong objects in a container. The device is composed of a main car used for integrally loading and unloading the container, and an auxiliary car used for loading and unloading materials in the container; the main car comprises a main car body, a lifting mechanism, a combined sling and a main car control mechanism; the lifting mechanism is arranged on a frame of the main car body, and the combined sling comprises a hanging sling frame and a telescopic combined sling; the control mechanism comprises a hydraulic control assembly and an electronic control assembly; the auxiliary car comprises an auxiliary car body, a front fork mechanism, a rear fork mechanism and an auxiliary car lifting control device; and the auxiliary car lifting control device is connected to a lifting unit and used for controlling the lifting unit to move up and down or lock up. According to the combined loading and unloading device and the loading and unloading method disclosed by the invention, through independent or cooperative work of the main car and the auxiliary car which can be separated, the loading and unloading requirements of the container as well as overweight boxlike objects and overlong objects in the container can be met simultaneously, and the inconvenience of loading and unloading the overweight and overlong objects in the prior art is overcome.

Description

technical field [0001] The invention relates to a lifting loading and unloading mechanical equipment, in particular to a combined loading and unloading device and a loading and unloading method for overweight or overlong objects in a container. Background technique [0002] At present, containerized transportation at home and abroad is vigorously promoted and vigorously developed. In the existing technology, there are mature machinery and equipment for the overall loading and unloading of containers. As for how to load and unload goods into and out of containers, the following two methods are most used now: [0003] 1. Load and unload the container from the special vehicle to the ground, and then use forklifts and other equipment to load and unload small and light goods. The disadvantage of this method is that large-scale special lifting equipment is required on site, and the price is expensive; at the same time, due to the limited load of forklifts that can enter the contai...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is also that it is difficult to load and unload overweight box-shaped objects and super-long materials, and forklift equipment cannot effectively complete the loading and unloading task; Use a forklift or other tools and equipment to push the goods into the box. As a result of this operation, the bottom plate of the container will be damaged, the box-shaped object cannot enter the other end of the closure at one time, and the long material cannot be loaded again, etc. insufficient
