Description

Technical Field

[0001] The invention discloses a detachable and assembled multi-purpose and multifunctional PC component hoisting frame tool, belonging to the field of assembled building hoisting equipment. Background Art

[0002] In recent years, prefabricated buildings have been used more and more widely as a new type of green construction method, but their lifting technology and lifting tools are not perfect.

[0003] For example, when lifting traditional composite panels, some use steel wire ropes for direct lifting, while others use simple steel poles as lifting tools; the lifting tools are not only single, but can only lift one component at a time, and the entire lifting process is not only time-consuming but also inefficient; secondly, the types of PC components that can be lifted by the lifting tools are relatively single, and some are only suitable for composite panel systems and cannot meet the lifting requirements of other types of PC components.

[0004] Moreover, the current lifting tools have a simple structure, and the tension distribution of the lifting cables is uneven during the lifting process, which can easily lead to defects such as cracks in the composite plates along the length direction during the lifting process. At the same time, when there is a sudden strong wind or a sudden change in the weather, the composite plates will suddenly shake violently during the lifting process. If there is no effective limiting device, it is very easy to cause the risk of falling off. Summary of the invention

[0011] Furthermore, the first-layer hanger long beam is provided with a main lifting lug, and the third-layer hanger long beam is provided with an anti-collision baffle.

[0012] Furthermore, the telescopic sling includes a first layer sling, a second layer sling and a third layer sling, the first layer sling, the second layer sling and the third layer sling are all composed of a sling long beam and two sling adjustment beams, the two sling adjustment beams are arranged on both sides of the sling long beam, and a plurality of sling adjustment holes are arranged on both the sling long beam and the sling adjustment beam, a pulley ear is connected to the sling adjustment holes on the sling long beam and the sling adjustment beam respectively through a fixing bolt, a first guide pulley is connected to the bottom of the pulley ear on the sling long beam, a lower sling is passed between the pulley ear on the sling adjustment beam and the first guide pulley, a second guide pulley is also arranged on the lower sling, and a hook is arranged at the bottom of the second guide pulley.
