Description

Technical Field

[0001] This utility model belongs to the field of hoisting engineering, and specifically relates to a lifting lug for tilting and hoisting. Background Technology

[0002] With the continuous development of the petrochemical industry, efficient construction has become a key focus of engineering projects. In the lifting and hoisting of steel structures and equipment, specific balance beams are required. However, balance beams are costly to manufacture and cannot be reused. More importantly, the presence of balance beams and rigging can lead to insufficient lifting height. Furthermore, balance beams are typically fabricated on-site, and their quality, safety, and economic efficiency can also impact the project. In addition, improper use or non-use of balance beams can cause the lifting lugs to break due to shearing forces, and the use of shackles can result in stress on dangerous areas and the possibility of shackle pins jamming. Utility Model Content

[0003] This utility model provides a lifting lug for tilting and hoisting to solve the technical problems existing in the prior art. Using this lifting lug, tilting and hoisting can be completed without the use of a balance beam, while avoiding the jamming of the shackle pin and ensuring hoisting safety.

[0004] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is: a lifting lug for flipping and hoisting, including a spoke plate fixed on the horizontal surface of the lifting part. The spoke plate is a variable amplitude spoke plate with an inclination angle and an eccentric angle. During hoisting, it is connected to the tying wire rope through a shackle. The angle θ between the tying wire rope and the center line of the shackle is between 0 and 5°. The center line of the shackle is parallel to the surface of the variable amplitude spoke plate.

[0005] Reinforcing ribs are provided on both sides of the spoke plate, and the reinforcing ribs are fixed to the horizontal surface of the lifting component.

[0006] Reinforcing plates are provided at the lifting holes on both sides of the spoke plate.

[0007] The lifting lug has a structural reinforcing rib plate within its working range, and the structural reinforcing rib plate is fixed to the lifting component.

[0008] The advantages and positive effects of this utility model are as follows: By providing tilt and deflection angles to the spokes, it avoids jamming of the shackle pins without the need for a balance beam, ensuring lifting safety and increasing the lifting height to meet on-site requirements. Engineering practice has proven its excellent performance. Furthermore, this utility model has a simple structure and is easy to use. Eliminating the need for a balance beam avoids the investment costs associated with balance beams and rigging, shortens the manufacturing period of lifting rigging, and reduces the impact of balance beams and rigging on lifting height, thereby improving the utilization efficiency of lifting machinery, avoiding the use of excessively heavy-duty, long-arm lifting machinery, and reducing construction costs.
