[0002] Ports are transportation hubs located along seas, rivers, lakes, and reservoirs, equipped with combined water and land transport facilities and facilities to ensure the safe entry, exit, and berthing of ships. Ports serve as hubs and junctions for both land and water transportation, serving as distribution centers for industrial and agricultural products and import and export goods. They also serve as places for ships to berth, load and unload cargo, embark and disembark passengers, and resupply supplies. Because port cargo often consists of bulky items, unloading equipment is essential for efficient loading and unloading.
[0003] After searching, the Chinese patent application number 202010213003.9 discloses a port unloading device, which relates to the field of unloading devices. The frame rod is sleeved on the cargo box, and the bottom rod is attached to the bottom of the cargo box. Under the action of the telescopic rod and the elastic rope, the entire lifting part will be connected to the outside of the cargo box, and then the cargo box will be lifted, loaded and unloaded and transferred through the lifting rod and the sling. The main body can rotate around the rotating gear disk, the base can move along the crossbeam, and the entire support frame can also move on the ground track, so that the working range of this device is expanded. Bearings are provided on the contact surface of the base and the crossbeam to reduce the resistance of the base movement. A ladder is provided on the support frame to facilitate inspection and maintenance by maintenance personnel. The base is movable and has a wider range of use. By providing a support rod, the device will not be unbalanced when lifting overweight cargo boxes. Rollers are provided at the lower end of the support rod so that the supporting effect of the support rod is not affected when the device moves.
[0004] Although the base of the above-mentioned patent can move along the crossbeam, the entire support frame can also move on the ground track, which expands the working range of the device, bearings are provided on the contact surface of the base and the crossbeam to reduce the resistance of the base movement, and a ladder is provided on the support frame to facilitate maintenance by maintenance personnel. The base is movable and has a wider range of use. By providing a support rod, the device will not be unbalanced when lifting an overweight cargo box, and a roller is provided at the lower end of the support rod so that the supporting function of the support rod is not affected when the device moves. However, in actual use, it is not convenient to accurately grab the goods. After the goods are grabbed, the goods are easily affected by air resistance and swing during the turning process, which affects the loading and unloading efficiency of the goods. At the same time, safety hazards are prone to occur, which brings inconvenience to the user.
[0005] Therefore, it is necessary to modify it to facilitate the precise grabbing of goods, avoid the swinging of goods when turning and moving, improve the efficiency of cargo loading and unloading, reduce safety hazards, and make it easier for users to use. Utility Model Content
