A method for assembling multiple suspension beams

technical field

The invention relates to the technical field of hangers, in particular to an assembly method of multiple hanging beams.

Background technique

Spreaders are widely used in various industrial sectors such as industrial and mining enterprises, ports, station warehouses, construction sites, ocean development, space navigation, etc., and play an important role in modern production, manufacturing and transportation. In large industries, whether it is ships or other large industries Products often use hanging beams to lift and shift heavy objects. Due to the relatively large volume of heavy objects and the distribution of lifting points far away, hanging beams must be used for hoisting. Due to the variety of segments and blocks in large-scale industries, The volume is relatively large, and in order to facilitate hoisting, large-span and long hanging beams are usually used to meet the hoisting requirements. For example, the Chinese patent application number is 201922150188.9, and the announcement date is 2020.08.28. It discloses an assembly method for a combined hanging beam, including at least One support beam and at least two suspension ring assemblies; the two ends of each support beam are detachably connected to the suspension ring assembly; the suspension ring assembly includes a suspension plate, and the suspension plate is provided with upper and lower suspension holes; the middle part of the suspension plate Two connecting plates distributed up and down are vertically fixed, and the left and right ends of the connecting plates are provided with two threaded connection holes; the supporting beam is in a square tube structure, and the two ends of the supporting beam are provided with threaded matching holes passing through the upper and lower walls of the supporting beam; The end of the plate is embedded between the upper and lower inner walls of the corresponding end of the support beam, and the upper and lower matching threaded holes are designed in a non-integrated manner, which is composed of multiple replaceable support beams and suspension ring components. Various load-bearing specifications are assembled according to hoisting needs, and multiple sets of support beams are connected in series according to the number of different lifting points to enhance versatility. At the same time, various length specifications can be set according to the size of different hanging objects, and can be replaced at any time. However, during the assembly process of this structure, it is necessary to connect the connecting plates at both ends of a long suspension beam to form a long suspension beam of another length, and then fix the long suspension beam through lifting lugs, and finally hang it through another length of long suspension beam. To pick up the goods, the long hanging beam after connecting multiple connecting plates needs to have a certain length, which makes it inconvenient to install the long hanging beam on the lifting equipment. In addition, the structure can only be used in the length direction for multiple For hoisting of goods, when large-scale goods need to be hoisted from four directions, only one long lifting beam is used to lift the goods. If the goods are not hoisted at the center of gravity of the goods, it is easy to cause the goods to shake during the hoisting process. , thus affecting the lifting effect.
