Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing and installation, and more specifically to a steel beam turning hoist. Background Art

[0002] During the manufacturing and installation process of steel structure bridges, according to the manufacturing process requirements, frequent turning over is required. After the rods are assembled on the tire frame, they need to be turned over for welding or hole making. However, it is impossible to weld the lifting lugs on the rods before the rods are formed. The weight of the rods is inconsistent, resulting in different specifications of the lifting lugs, and the lifting lugs cannot be reused. During the trial assembly, pre-assembly or installation process, the steel beams need to be turned over to achieve the purpose of assembly, so the design and use of steel beam turning hoists also came into being. Therefore, it is necessary to design a movable and detachable hoist with sufficient load-bearing capacity to achieve the purpose of turning over the rods, while reducing the production, manufacturing and installation costs of the enterprise. Utility Model Content

[0003] In view of this, the utility model provides a steel beam turning hoist, which does not need to install a lifting ring on the steel beam, avoiding the damage of the welding lifting ring to the steel beam. In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0004] The utility model provides a steel beam turning hoist, comprising:

[0005] A first connecting plate and a second connecting plate, wherein the first connecting plate and the second connecting plate are detachably connected, and a shape enclosed by the inner walls of the first connecting plate and the second connecting plate is adapted to the outer surface of the steel beam to be turned over, and the first connecting plate and / or the second connecting plate are both provided with lifting rings.

[0006] Furthermore, the first connecting plate overlaps with the second connecting plate at the connection, and through holes are provided at the overlapping parts of the first connecting plate and the second connecting plate. The through holes on the first connecting plate are the same size as the through holes on the second connecting plate, and a pin is used to pass through the through holes on the first connecting plate and the through holes on the second connecting plate in sequence to achieve the connection between the first connecting plate and the second connecting plate.

[0007] Furthermore, the inner walls of the first connecting plate and the second connecting plate are both provided with stiffening rings.

[0008] Furthermore, the lifting ring is a through hole provided on the first connecting plate and / or the second connecting plate, and reinforcing plates are provided around the lifting ring.

[0009] Furthermore, the distance between the inner wall and the outer wall of the first connecting plate and the second connecting plate is greater than 250 mm.

[0010] Furthermore, a plurality of lifting rings are provided on the first connecting plate and the second connecting plate.

[0011] It can be seen from the above technical solution that compared with the prior art, the utility model discloses a steel beam turning hoist, in which lifting rings are arranged on the first connecting plate and the second connecting plate. There is no need to install lifting rings on the steel beam. The steel beam can be turned over only with the lifting device, thus avoiding damage to the steel beam. The lifting device can be reused many times, reducing the cost of manufacturing and installation. BRIEF DESCRIPTION OF THE DRAWINGS
