Description

Technical Field

[0001] The utility model relates to the technical field of material lifting devices, in particular to a material lifting device for steel structure building construction. Background Art

[0002] Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which have higher strength and better earthquake resistance. In addition, since the components can be manufactured in factories and installed on site, the construction period is greatly reduced. Since steel is reusable, it can greatly reduce construction waste and is more environmentally friendly. Therefore, it is widely used in industrial and civil buildings. The material lifting device for steel structure construction is a hoisting device for lifting steel structure hooks during steel structure construction.

[0003] For example, the patent with the authorization announcement number CN206752808U, entitled "A Modular Spreader," includes a support rod with a pair of lifting rings symmetrically arranged above the support rod. The lifting rings are connected to the top of the building, and the support rod is suspended in the air through the lifting rings. The support rod is equipped with two hooks, the hook openings of which are arranged opposite to each other. A sliding groove is provided below the support rod, and the hook slides along the support rod through the sliding groove. The sliding groove is provided on the lower surface of the support rod, and the hook can slide along the support rod in the sliding groove. In actual construction, the two relatively arranged hooks can adjust the distance between each other according to the equipment or plates to be hoisted to meet the hoisting requirements.

[0004] Similar to the above-mentioned application, in the prior art, when a material lifting device for steel structure construction is used to suspend and lift long steel strips, two movable hooks are often provided for use together. Although the movable hooks can be slid and adjusted to their positions at will, in actual use, the positions of the two hooks are often not symmetrical with respect to the center of the suspension and lifting position, affecting the stability and safety of the lifting. Utility Model Content

[0005] The purpose of the present invention is to overcome the problem in the prior art that when long strips of steel are suspended and lifted, two movable hooks are often set for use together. Although the movable hooks can slide and adjust their positions at will, in actual use, the positions of the two hooks are easily not symmetrical with respect to the center of the suspension and lifting position, affecting the stability and safety of the lifting. A material lifting device for steel structure building construction is provided. By setting an interlocking adjustment mechanism, when the staff adjusts the position of the adjustment sleeve according to profiles of different lengths, when the staff adjusts any adjustment sleeve, the interlocking adjustment mechanism passively and automatically adjusts the other adjustment sleeve synchronously, so that the two adjustment sleeves always remain symmetrical with each other about the center hanger, preventing the positions of the two adjustment sleeves from deviating, affecting the stability and safety during suspension and lifting.
