Detailed Description
The present invention will be described in detail with reference to fig. 1 to 5, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides an arch bridge lattice beam cable hoisting light sling through improvement, as shown in figures 1-5, which can be implemented as follows;
the lifting appliance is divided into three parts, namely a beam body 1, lifting lugs 2 and splicing plates. The beam body is an I-shaped steel beam formed by welding steel plates, and the steel beam can be designed into a variable cross-section steel beam according to the stress condition; the lifting lug is welded at the end part of the beam body; the splice plates are divided into a web splice plate 3, an upper flange splice plate 4 and a lower flange splice plate 5. According to the stress calculation, bolt holes 7 are drilled in the web plate, the upper flange plate and the lower flange plate of the connecting part of the steel beam and the lattice beam of the lifting appliance, and bolt holes are drilled in the corresponding positions of the splicing plates. All drilling work can be done in the gridwork factory.
Before hoisting, the grid beam hanger is connected with a hoisting point fork lug 6 of a cable crane through a pin shaft and stays above a hoisting position, after the grid beam is transported to the hoisting position, the grid beam is butted with a web plate, a top plate and a bottom plate of the hanger, splicing plates are installed, bolts (common bolts) are screwed, the connection between the hanger and the grid beam is completed, the transverse widening of the grid beam is realized, and the cable crane can start hoisting.
