Stepless-adjustment telescopic hoisting distribution beam device

Abstract

The invention provides a stepless adjustment telescopic hoisting distribution beam device which comprises a hoisting main beam, two box-type secondary beams are symmetrically installed in the hoisting main beam, and the two box-type secondary beams are fixed through pin shafts and can horizontally stretch out and draw back in the hoisting main beam, so that the stepless adjustment telescopic hoisting distribution beam device can be suitable for hoisting operation of components with different lengths, the application range is wider, and the hoisting efficiency is improved. And meanwhile, due to the telescopic structure, the transportation and storage space can be saved. The upper part of the hoisting main beam is connected with a plurality of hoisting steel wire ropes, the lower part of the hoisting main beam and the lower part of the box type secondary beam are connected with rigging, the rigging is connected with a lifting lug, and the lifting lug is connected with a hoisting object lifting lug on a to-be-hoisted hoisting object; by means of the lifting sling, horizontal rotation of a lifted object in the lifting process can be avoided, reasonable stress of a component in the lifting process can be guaranteed, and the mounting position of the lifting sling can be reasonably selected according to the gravity center of the irregular super-long component and the position of a lifting lug of the lifted object.

Description

technical field [0001] The invention belongs to the technical field of hoisting construction, and in particular relates to a stepless adjustable telescopic hoisting distribution beam device. Background technique [0002] During the construction of steel structure buildings, the overall hoisting of super long components is often involved. Conventional components can be hoisted directly by connecting with steel wire ropes. It is prone to deformation and even the risk of slipping, which not only affects the quality of the component itself, but more importantly, there is a greater safety hazard. Therefore, it is necessary to design an auxiliary hoisting tool suitable for hoisting operations of super-long components. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a stepless adjustable telescopic hoisting distribution beam device, in which two box-shaped secondary beams are installed through pin shafts in the hoisti...
