Description

Technical Field

[0001] The utility model relates to the technical field of steel truss hoisting and positioning, in particular to a large-span steel truss hoisting auxiliary positioning device. Background Art

[0002] Steel trusses are trusses made of steel and are often used in roof structures of industrial and civil buildings, crane beams, bridges, etc. as the main load-bearing components. Steel trusses are large in size and generally need to be moved to the installation location by lifting equipment, and then the steel trusses are fixed and installed at the location where they need to be installed.

[0003] For example, a steel truss lifting tool provided in a Chinese patent application with publication number CN218290146U includes a first steel hanging plate and a second steel hanging plate, the first steel hanging plate and the second steel hanging plate are relatively closed to form a lifting ring with a circular cross-section, one side of the first steel hanging plate and the second steel hanging plate are rotatably connected by a rotating shaft, the other side of the first steel hanging plate is provided with two second ear plates extending downward along its side surface, the middle position of the other side of the second steel hanging plate is provided with a second first fixing plate extending upward along its side surface, the second first fixing plate is arranged between the two second ear plates, the screw passes through the through holes on the second ear plate and the second first fixing plate and is locked and positioned by a nut, and a lifting ring is arranged on the top surface of the first steel hanging plate. This technical solution forms a lifting ring with a circular cross-section through the first steel hanging plate and the second steel hanging plate, which will not cause bumps to the structure of the building during lifting, and the lifting ring is sleeved on the truss, which avoids the subsequent work of cutting off the lifting ears and repairing paint caused by welding lifting ears and bundling steel wire ropes on the pipe truss, thereby reducing costs and improving safety.

[0004] However, the following problems still exist in this technical solution: the distance between the first steel hanger plate and the second steel hanger plate in this technical solution is fixed and cannot be adjusted according to the width of the steel truss, so that steel trusses of different specifications cannot be hoisted, which has certain limitations. Utility Model Content

[0005] To this end, an embodiment of the utility model provides a steel truss lifting tool to solve the problem in the prior art that steel trusses of different specifications cannot be lifted due to the fixed distance between the first steel hanging plate and the second steel hanging plate.
