Description

Technical Field

[0001] The invention relates to the technical field of cargo handling and loading and unloading, and in particular to a quick loading and unloading device for a mountain port. Background Art

[0002] In the harsh operating environment of mountain ports, manual loading and unloading is prone to fatigue, mistakes, etc., resulting in cargo damage or safety accidents. The rapid loading and unloading device can operate according to preset procedures and standards through precise control systems and mechanical structures, reducing loading and unloading errors caused by human factors, reducing the labor intensity of staff, improving cargo loading and unloading efficiency, and at the same time reducing cargo damage rates and safety risks.

[0003] A Chinese patent discloses a "port cargo rapid loading and unloading device", and its application number is "202011459719.3". This patent mainly adjusts the height of the cross plate by controlling the hydraulic rod, and keeps the cross plate horizontal through the cooperation of the limit slide groove and the guide plate. The start motor drives the transmission shaft to rotate, so that the screw rods on both sides rotate, and the lifting plate drives the fork to move up and down between the guide rail tubes. The fork transports the bagged goods to the cross plate, which is convenient for workers to load and unload. The device can adjust the conveying height, which is convenient for various loading and unloading requirements. At the same time, the spacing between the forks is adjustable, which can adapt to a variety of bagged goods, and the actual use effect is good. However, the cross plate of the loading and unloading device does not have a limiting device. If the cross plate moves left and right during the loading and unloading process of the goods, the inclination angle of the lifting assembly will change, thereby affecting the stability of the cargo transportation process. At the same time, the loading and unloading device only relies on the fork to fix the goods, and the stability is poor. The goods are very easy to fall during transportation, thereby causing damage to the goods and economic losses. Summary of the invention
