Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a vacuum suction cup lifting equipment for lifting precast concrete ring components. Background Technology

[0002] In the traditional hoisting of concrete ring components, the components are often lifted vertically using horizontal clamps. However, this method often has the following disadvantages: the lifting speed is slow, the safety factor is low during the movement after lifting, the use of gravity locking at the moment of lifting may cause the component to fall off, the labor intensity of the workers is high, the operation is cumbersome and requires the workers to have certain technical knowledge, and once the component falls off, it will cause equipment damage, or even seriously endanger the personal safety of the workers, thus affecting the production rhythm of the entire production line.

[0003] With the development of industrialized construction and the rapid advancement of production line automation, vacuum suction cup lifting equipment is increasingly widely used in the construction of precast tunnel segments and wind turbine hybrid tower segments. Vacuum suction cup lifting equipment offers advantages such as stable quality, high production efficiency, and the ability to effectively shorten on-site construction time. It is crucial for achieving overall automation of the precast tunnel segment production line and the main production line of wind turbine hybrid towers. The design and manufacturing of vacuum suction cup lifting equipment directly affect the safety of lifting precast components and the overall production efficiency of the production line.

[0040] In use, firstly, adjust the relative position of the adjustable hanger 4 to the main beam 3 of the vacuum chamber according to the size of the ring component. After confirming the position, use a pin to pass through the corresponding pin hole and positioning hole to fix the adjustable hanger 4. Then, rotate all the unit suction cups 7 to a suitable angle one by one to attach them to the surface of the ring component and turn on the independent vacuum pressure switch on the corresponding unit suction cup 7 to complete the adsorption. Finally, use a steel wire rope to connect the suction cup lifting lug 301 to the lifting device.

[0041] Compared to traditional vacuum suction cup lifting devices, this utility model has a more reasonable structure. The relative position of the adjustable lifting bracket on the main beam of the vacuum chamber is adjusted by sliding, and fixed with pins. It can be flexibly adjusted according to the actual size of the ring component, making it more adaptable. In addition, the design of double beams, several suction cup panel assemblies, and multiple sets of slide rails on each side of the main beam of the vacuum chamber can effectively improve the stability of the overall lifting process.
