Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, specifically to a multi-machine universal general cargo lifting equipment with limiting and anti-detachment features, and its lifting method. Background Technology

[0002] The most notable characteristics of general cargo (such as ton bags, steel structures, large equipment, geotextile rolls, etc.) are their diverse types, specifications, and shapes. This non-standardized nature of cargo presents significant challenges to loading and unloading operations at ports, docks, and logistics yards. General cargo logistics is undergoing a phase of simultaneous expansion in scale and upgrading of cargo structure. Emerging cargo sources, represented by wind turbine blades, large construction machinery, and complete sets of industrial equipment, are growing rapidly, with cargo shapes shifting from relatively regular traditional goods to longer, heavier, and more irregular large equipment. This change places demands on the load-bearing capacity, versatility, and multi-machine collaboration capabilities of lifting equipment far exceeding those of traditional operations. Furthermore, the specifications of traditional cargo types such as steel are becoming increasingly diversified, and existing lifting equipment is no longer adequate in terms of design capacity and adaptability to match the dimensions of new cargoes. Frequent changes in lifting equipment lead to accumulated downtime, becoming a prominent bottleneck restricting production efficiency. C-shaped lifting equipment is often used when lifting steel coils or tubular general cargo.

[0003] Chinese patent CN103950825A discloses a steel strip coil lifting device, including hooks, a boom, and a crossbar. The boom includes a crossbar and two downward-facing left and right longitudinal arms at both ends of the crossbar. Hooks are respectively installed at the lower ends of the left and right longitudinal arms. The two ends of the crossbar are hooked by the left and right hooks. The crossbar is provided with lifting lugs. The distance between the left and right longitudinal arms is greater than the thickness of the steel strip coil, the length of the crossbar is greater than the distance between the left and right longitudinal arms, and the distance from the hook to the crossbar is greater than the radius of the steel strip coil. Baffles are provided at both ends of the crossbar to prevent the hooks from falling off. Using this invention can greatly reduce material deformation, correspondingly reduce material loss, and improve the safety factor. However, when lifting steel coils or tubular miscellaneous goods, the boom position is fixed, making it impossible to lift goods of different widths. Furthermore, tubular miscellaneous goods are prone to swaying and falling off during lifting and transportation, and the stability of goods transportation needs to be improved. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides: a multi-machine universal cargo lifting device with limiting and anti-detachment mechanism and a lifting method thereof, comprising: A fixing block having a rectangular block structure and a positioning block disposed on the top of the fixing block, wherein a lifting lug is fixedly connected to the top of the positioning block; An extension frame having a rectangular frame structure and a support plate disposed on the inner wall of the extension frame, wherein a suspension device is sleeved and slidably connected to the outer side of the support plate. The suspension device includes: The movable board is provided in two sets. A first electric telescopic rod is fixedly connected to one side of the movable board, and a movable frame is fixedly connected to the bottom of the movable board. The boom has a C-shaped structure and a suspension frame at the top of the boom. A limit device is fixedly connected to one side of the boom. The moving frame drives the suspension frame and the boom to move, so that the boom can be inserted into the center of the tubular goods. By inserting two sets of booms from both ends of the tubular goods, the tubular goods can be clamped and lifted. It can lift goods of different widths and specifications, and the adjustment method is quick and simple.

[0005] Preferably, the limiting device includes: The limiting post has a circular column structure and a second electric telescopic rod disposed at one end of the limiting post. A fixing sleeve is sleeved and fixedly connected to the outside of the fixed end of the second electric telescopic rod, and a connecting frame is fixedly connected to the top of the fixing sleeve. The curved top clamping plate has a semi-circular plate structure and an anti-slip strip on its outer side. A third electric telescopic rod is fixedly connected to one side of the curved top clamping plate. A reinforcing frame is sleeved and fixedly connected to the fixed end of the third electric telescopic rod. The movable end of the third electric telescopic rod pushes the curved top clamping plate closer and closer to the inner wall of the tubular goods until the curved top clamping plate is pressed against the inner wall of the tubular goods. Since there are multiple sets of curved top clamping plates, the center of the tubular goods can be supported and clamped by multiple sets of curved top clamping plates, which prevents the tubular goods from shaking and falling off during lifting and transportation, thus improving the stability of cargo transportation. Since there are multiple sets of curved top clamping plates and each set of curved top clamping plates corresponds to a different set of third electric telescopic rods, the extension length of each set of third electric telescopic rods can be adjusted independently. This allows for the support of tubular goods of different diameters, as well as the center support of irregularly shaped tubular goods, effectively improving adaptability.

[0006] Preferably, one side of the extension frame is fixedly connected to the side of the fixing block, and two sets of extension frames are provided, with the two sets of extension frames symmetrically distributed on both sides of the fixing block.

[0007] Preferably, both sides of the support plate are fixedly connected to the inner wall of the extension frame, and the bottom of the positioning block is fixedly connected to the top of the fixing block.

[0008] Preferably, the fixed end of the first electric telescopic rod is fixedly connected to the side of the positioning block, and the movable frame is sleeved on the outside of the support plate and slidably connected to the outer wall of the support plate.

[0009] Preferably, the boom passes through the suspension frame and is fixedly connected to the inner side of the suspension frame, and the top of the suspension frame is fixedly connected to the bottom of the movable frame.

[0010] Preferably, the movable end of the second electric telescopic rod is fixedly connected to one end of the limiting post, and the end of the connecting frame away from the fixed sleeve is fixedly connected to the outer side of the boom.

[0011] Preferably, the anti-slip strips are provided in multiple sets, and the multiple sets of anti-slip strips are evenly distributed on the outer side of the arc-shaped top clamping plate, and one side of the reinforcing frame is fixedly connected to the outer wall of the limiting column.
