Description

Technical Field

[0001] The utility model relates to the technical field of hoisting and installing concrete tower tubes and tower pieces, in particular to a hoisting tool with an adjustable multi-hoisting point balance beam. Background Art

[0002] In current wind power concrete steel-concrete tower construction, tower segments are usually prefabricated and transported in multiple pieces. They need to be transported to the site, assembled into a cylinder, and then hoisted and installed. However, after assembly is completed, a flexible sling is used to lift the upper end of the tower ring. The disadvantage of using a flexible sling to lift the tower is that the center point of the hook is difficult to control during lifting, and the tower may swing in the air during lifting, posing a construction safety hazard. After lifting, the upper section of the tower segment will be subjected to an inward stress, and the lower section of the tower will experience an opposite outward force similar to a seesaw. The adhesive on the upper end of the tower will be squeezed, even causing slight cracks in the tower segments. The adhesive on the lower section will be subjected to tension, which not only affects the appearance of the tower, but also its quality. Later, it may cause a series of problems such as tower leakage. Therefore, we propose a multi-point balancing device suitable for segment lifting.

[0003] An adjustable multi-hanging point balance beam lifting tool is now proposed. Through the balance platform, the center position of the tower can be easily confirmed, the swing during lifting is minimized, and the lifting efficiency and safety are improved. The crane hook is first docked with the balance platform to decompose the forces in two directions, unloading the inward force of the tower so that the inward force is borne entirely by the balance platform, protecting the tower from inward destructive force during construction, and finally directly applying vertical force to the tower to achieve safe lifting.
