Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure hoisting, in particular to a hoisting device for steel structure installation. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure is widely used in large factories, venues, super high-rise buildings and other fields because of its light weight and simple construction. Among them, I-shaped steel is a common type of steel structure. Traditionally, I-shaped steel is usually hoisted by tying I-shaped steel with steel ropes. This hoisting method is inefficient and prone to the risk of steel structure falling.

[0003] After searching, it was found that in order to solve this problem, the utility model patent with the authorization announcement number CN217808338U provides a lifting device for steel structure profile installation. In this device, the clamping clamp is embedded in the inner groove of the I-shaped steel structure, so as to meet the requirements of efficient and stable lifting of I-shaped steel structures of different widths.

[0004] However, in this solution, the structure of the clamping and fixing pliers is a simple L-shaped structure. When hoisting the I-shaped steel, there is still a certain distance between the upper surface of the I-shaped steel and the lower surface of the fixed shell. The clamping stability of the I-shaped steel between the two sets of clamping and fixing pliers is only achieved by the lateral force applied by the two sets of clamping and fixing pliers. During the hoisting process, if the I-shaped steel shakes due to the influence of the external environment, there is still a risk that the I-shaped steel will be separated from the two sets of clamping and fixing pliers, thus posing a safety hazard to the hoisting.
