Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary hoisting, in particular to a hoisting device for prefabricated components of assembled buildings. Background Art

[0002] Prefabricated components are made of reinforced concrete, such as prefabricated wall panels, prefabricated floor slabs, prefabricated bridge T-beams, etc. They are widely used in actual engineering construction and can greatly save the construction period of the project. In the process of hoisting prefabricated components, steel wire ropes are usually used to fix the prefabricated components on the hook of the crane, and then hoisted by the crane. During the hoisting process, if the length of the steel wire rope is inconsistent or the position of the steel wire rope is not appropriate, the hoisted prefabricated components may be tilted, which is not conducive to the lifting and installation of the prefabricated components.

[0003] Patent authorization announcement number CN 217808330 U discloses a lifting device for intelligently adjusting assembled prefabricated building components. The lifting device for intelligently adjusting assembled prefabricated building components includes: a horizontal plate; a shell, the shell is fixedly mounted on the top of the horizontal plate, and the top of the shell is provided with an opening; two movable plates, both of which are arranged below the horizontal plate; a rotating shaft, the rotating shaft is fixedly mounted on the top of the horizontal plate; and a connecting plate, the connecting plate is rotatably mounted on the top of the rotating shaft. The lifting device for intelligently adjusting assembled prefabricated building components provided by the utility model has the advantages of being easy to adjust the horizontal angle, being relatively convenient to operate, saving time and effort, and having a good use effect.

[0004] However, the above technical solution has the following shortcomings: although the clamping mechanism formed by the cooperation of the horizontal plate and the movable plate with the motor and the screw can clamp the prefabricated components, the space at the installation position of the prefabricated components is generally limited. In actual use, the horizontal plate is easy to collide with other objects around the installation position, which not only affects the lifting of the prefabricated components, but also affects the installation of the prefabricated components.
