Description

Technical Field

[0001] The utility model relates to a sling for a suspension bridge, in particular to an assembly device for a sling anchor of a suspension bridge, and belongs to the technical field of metal product processing. Background Art

[0002] As the core load-bearing component connecting the main cables and stiffening beams on a suspension bridge, the suspender cable bears the static load of the bridge for a long time, the pulsating cyclic load stress caused by road vehicle operation and wind vibration, as well as sunlight exposure and rain erosion. Its quality and surface condition are related to the operational safety and life of the entire bridge.

[0003] During the sling production process, the assembly of the sling anchor is a key step in the production process. It is necessary to screw the external thread of the sling fork ear plate and the internal thread of the anchor cup together to achieve the designed calibrated cable length requirements.

[0004] At present, the assembly of suspension cable anchors for suspension bridges in the industry is usually carried out in traditional ways. The traditional methods mainly include vise wrenches, hinge wrenches, and overhead cranes with sling friction screw threads. Among them, vise wrenches and hinge wrenches are commonly used assembly tools. After use, the surface of the anchor is severely damaged and must be repainted; the overhead crane with sling friction screw threads is suitable for screwing cylindrical screws or nuts, and requires strict conditions such as large thread matching tolerances. During the lifting process of the overhead crane, safety hazards such as thread jamming, thread damage, slipping, and slanted lifting are prone to occur. Utility Model Content
