Abstract

The invention relates to the technical field of crane rigging, in particular to a crane rigging for hoisting large tubular weights, including a steering mechanism, a positioning mechanism, an auxiliary fixing mechanism, and a fixing mechanism; The two ends of the steering mechanism, the auxiliary fixing mechanism and the fixing mechanism are fixedly installed at the bottom of the connecting plate, and the steering mechanism can adjust the installation angle of the tubular weight, which is more practical; the auxiliary gear cooperates with the rack to adjust the installation angle of the tubular weight The installation angle provides auxiliary power, which makes the installation angle more accurate and reduces the labor force; the position adjustment mechanism can adjust the center position of the tubular weight, and can also adjust its own length according to the length of the tubular weight, which provides a safety guarantee for the fixing of the tubular weight; The auxiliary fixing mechanism and the fixing mechanism cooperate with each other to fix the middle of the tubular weight, which improves the safety performance and has high practicability.

Description

technical field [0001] The invention relates to the technical field of crane slings, in particular to a crane sling used for hoisting large tubular weights. Background technique [0002] With the continuous development of industry, the quality of objects that people need to lift in industrial production and construction industries is also increasing. Traditional ropes can no longer fully bear the weight of people hanging objects. Later, people made steel wire ropes by twisting steel wire bundles that meet the requirements of mechanical properties and geometric dimensions according to certain rules. It is first twisted into strands by multi-layer steel wire. Then take the core as the center. It is twisted into a helical shape by a certain number of strands. It consists of steel wire, rope core and grease. After further processing, a convenient-to-use wire rope sling was made. Now it is widely used in steel and chemical industry. Transportation, port and other industries...
